Abstract
This study examines the social determinants of psychosomatic complaints
in young adolescents. Using data from the Health Behaviour in School-aged
Children (HBSC) study, psychosomatic complaints are studied in 98,773
adolescents (11- and 13-year-olds; 48% 11-year-olds, 52% 13-year-olds; 52%
females, 48% males) from 34 European countries. Individual-level determinants, including family-, peer- and school-related factors as well as countrylevel determinants (Human Development Index [HDI]) are considered. In
line with existing evidence, results revealed more psychosomatic complaints
in young adolescents experiencing stress inducing familial-, peer- and schoolrelated factors. Negative effects of poor friendships, negative class climate,
school pressure, and high media use were more pronounced for girls. After
controlling for these factors, a higher HDI was related to a lower risk for
psychosomatic complaints. Gender-specific intervention programs should
aim at improving the quality of relationships, especially among peers, to prevent psychosomatic complaints among young adolescents.

Background
Psychosomatic complaints are important indicators of psychosocial health
(Piko, 2007) and well-being (Berntsson, Köhler, & Gustafsson, 2001). By
definition, they are “subjective physical complaints (headache, stomach
ache, back ache, and dizziness) as well as psychological complaints (feeling
low, irritability, nervousness, and difficulty in getting to sleep)” that are not
caused by an underlying physical disease (Natvig, Albrektsen, Anderssen, &
Qvarntstrøm, 1999, p. 362). Findings from studies with children and adolescents provide support for the relationship between psychosomatic complaints
and poor life satisfaction, depression (Piko, 2006), negative moods (Jellesma,
Rieffe, Terwogt, & Kneepkens, 2006), unhappiness (Natvig, Albrektsen, &
Qvarnstrom, 2003), and a lower health perception (Piko, 2007). The period
of adolescence is a vulnerable time of developmental changes which are
highly susceptible to psychosomatic complaints.
Early adolescence is an important developmental period as it marks the
transition between childhood and adolescence. It is characterized by increased
desire for “autonomy from adult control [. . .], peer orientation, self-focus,
self-consciousness, salience-of-identity issues; concern over sexual

relationships; and capacity for abstract cognitive activity” (Eccles, Lord, &
Midgley, 1991, p. 534). Eccles and Midgley (1990) have suggested various
reasons for the negative changes which begin during early adolescence,
including “intrapsychic upheaval” which leads to motivational and behavioral problems, the simultaneous timing of school transition and major developmental changes, and the quality of school environments (p. 135). The last
20 years has seen an increase in the number of cross-cultural studies on child
and adolescent development across cultures (Gielen & Roopnarine, 2004).
Most frequently, these have been prevalence studies comparing age and gender differences; however, more recently, studies have taken account of
important social contexts, such as the family, peers, and school.
Psychosomatic complaints are thought to be stress related. Frequent or
sustained stress leads to emotional and physiological responses, which have
a clear effect on the development of frequent complaints (Brosschot, 2002).
Both individual-level and country-level factors, such as the nation’s wealth
(gross national product) or its distribution (Gini coefficient), play a role in
children’s well-being (Holstein et al., 2009). The present article extends this
knowledge by examining the relative importance of the social determinants
on health complaints in young adolescents. The robustness of the Health
Behaviour in School-aged Children (HBSC) study (large sample size, multinational data) provides an opportunity to investigate the impact of both
individual- and country-level factors on psychosomatic complaints across
Europe and North America.
Psychosomatic Complaints in Young Adolescents
Research has demonstrated an increased risk for psychosomatic complaints
in the presence of psychosocial stressors, such as parental conflicts
(Hurrelmann, Engel, Holler, & Nordlohne, 1988), bullying, lack of acceptance by peers, lack of support from parents and teachers (Gerber & Pühse,
2008; Natvig et al., 1999). Given the increase in psychosomatic complaints
(Berntsson & Köhler, 2001; Hagquist, 2009; Karvonen, Vikat, & Rimpelä,
2005), it is important to gain a better understanding of the distribution and
origin of this association. The most common symptoms reported by young
adolescents are back pain, neck pain, and headache (Bandell-Hoekstra et al.,
2001; Hakala, Rimpelä, Salminen, Virtanen, & Rimpelä, 2002; Haugland,
Wold, Stevenson, Aaroe, & Woynarowska, 2001; Jellesma et al., 2006).
Other complaints frequently reported are stomach complaints and loss of
appetite (Berntsson et al., 2001; Jellesma et al., 2006).

Ottova et al.
Evidence suggests age and gender to be important factors in reported complaints. Studies show that older adolescents have higher rates of complaints
(Cavallo et al., 2006; Ghandour, Overpeck, Huang, Kogan, & Scheidt, 2004;
Haugland et al., 2001; Karademas, Peppa, Fotiou, & Kokkevi, 2008; Tanaka,
Tamai, Terashima, Takenaka, & Tanaka, 2000) and that gender differences
increase with age. The highest rates of psychosomatic complaints are generally reported by 15-year-old girls (Haugland et al., 2001; West & Sweeting,
2003). However, while older girls report more complaints than their younger
peers, older boys tend to report fewer complaints than younger ones (Marschall,
1989). There is clear evidence that boys and girls differ in the types of psychosomatic complaints they commonly report (Natvig et al., 1999). The frequency
and intensity of complaints is higher in girls and they generally are more likely
to report having had more than two complaints at least once a week (Cavallo
et al., 2006).
Evidence on the relationship between stress and health complaints has been
confirmed by a number of studies; however, less frequent are the studies of
young people (Sundblad, Jansson, Saartok, Renström, & Engström, 2008).
Research also suggests that psychosocial complaints may be a stress reaction
to psychosocial tension (Holler-Nowitzki, 1994). Studies among adults have
pointed to an association between workplace psychosocial factors and stress
(Haukka et al., 2010). Likewise, increasing demands, academic pressure at
school, and fear of failure may result in the experience of stress among young
people (Eriksson & Sellström, 2010; Hurrelmann et al., 1988). Stress increases
with age, and girls are more affected than boys (Sundblad et al., 2008). Such
risk factors can of course be offset by the presence of protective factors.
Torsheim and Wold (2001) showed an inverse relationship between stress and
sense of coherence, suggesting that protective factors (or assets) have a role to
play in health and well-being during adolescence.
Clearly, psychosomatic complaints are determined by a number of factors
operating through social stress at a micro (individual) level, such as family
problems, peer pressure, unsuccessful coping strategies (Brill, Patel, &
MacDonald, 2001), as well as factors at the macro (societal or national) level
(e.g., Holstein et al., 2009; Torsheim, Currie, Boyce, & Samdal, 2006). The
complexity of these determinants and the rationale for their inclusion in the
present study are described below.
Individual-Level Factors Related
to Psychosomatic Complaints
Familial context. Studies confirm an association between adolescents’
health and well-being and family and school factors (Gaspar, Matos, Ribeiro,
Downloaded from jea.sagepub.com at NUI, Galway on June 12, 2012
130
Journal of Early Adolescence 32(1)
Leal, & Ferreira, 2009; Karademas et al., 2008), including good family climate and high social support (Wille, Bettge, Ravens-Sieberer, & the BELLA
Study Group, 2008), positive family, and school climate (Karademas et al.,
2008). In contrast, family conflicts and stress were found to be associated
with more health problems (Karvonen et al., 2005). Poor communication
with parents emerged as more strongly associated with psychological health
complaints in adolescents than poor peer communication (Moreno et al.,
2009). Family structure (in particular, single-parent families) and low educational level of the parents have an additional negative impact on children’s
health (Berntsson & Köhler, 2001; Brolin Laftman & Östberg, 2006; Östberg,
Alfven, & Hjern, 2006).
Peer relations. Research into peer relations has identified an association
between harassment and recurrent pain (Hjern, Alfven, & Östberg, 2008),
and studies have shown that higher rates of health complaints are experienced
by victims as well as by perpetrators of bullying (Gini, 2008; Richter, Bowles,
Melzer, & Hurrelmann, 2007). Girls who experience bullying report headaches, back aches, and morning fatigue more frequently than those with no
such negative experiences (Ghandour et al., 2004). Moreno et al. (2009) also
showed that good peer communication with same-sex friends is associated
with lower number of complaints.
School environment. School and extracurricular activities, such as homework, clubs, friendships, and other social activities, are some of the key factors for children’s psychosocial development (Samdal, Nutbeam, Wold, &
Kannas, 1998; Ravens-Sieberer, Freeman, Kokonyei, Thomas, & Erhart,
2009). Poor perception of the school environment can be a major stressor
during the school years in young adolescents (Hjern et al., 2008). Eccles &
Midgley (1990) showed a marked decrease in self-confidence in school
achievement and mastery of school work in the transition from childhood
into adolescence. Other studies have confirmed an association between
school-related stress, such as feeling pressured by school work, and psychosomatic complaints (Gerber & Pühse, 2008; Karademas et al., 2008; Natvig
et al., 1999). Older adolescents experience increased school pressure (Cavallo
et al., 2006). Poor academic achievement has been shown to be associated
with nearly a threefold greater chance of poor or fair self-perceived health
(Piko, 2007). Karvonen et al. (2005) found that both—the absence of as well
as academic demands—are associated with psychosomatic health complaints.
Other authors found that factors such as teacher support or resources at school
play an even greater role (Eriksson & Sellström, 2010). In fact, several studies have confirmed a protective effect of social support from peers (Natvig et al.,
1999; Santinello, Vieno, & De Vogli, 2009).

Ottova et al.
Physical activity and sedentary behaviors. Studies show that children who
engage in sedentary behaviors, such as playing TV games (Tanaka et al.,
2000), computer-related activities (Hakala, Rimpelä, Saarni, & Salminen,
2006), and screen-based activities in general (Torsheim et al., 2010), have a
higher rate of somatic complaints (Bakoula, Kapi, Veltsista, Kavadias, &
Kolaitis, 2006), and the risk for complaints increases with the number of
hours spent sedentary (Tanaka et al., 2000). One possible mechanism is that
sedentary behaviors sustained over a period of time cause muscle tension
which may then lead to pain (Straker et al., 2008; Torsheim et al., 2010). A
side effect of many hours spent on screen-based activities is that it potentially
reduces the number of hours for parent-child interaction and, in this way,
negatively affects child health (Tanaka et al., 2000). A distinct protective
effect of physical activity could not be confirmed (Gerber & Pühse, 2008;
Ghandour et al., 2004), but it may moderate the relationship between stress
and psychosomatic complaints (Haugland, Wold, & Torsheim, 2003). Sundblad
et al. (2008) found a correlation between physical activity and positive perceived health.
Socioeconomic indicators. Studies have pointed at associations between psychosomatic complaints and sociodemographic risk factors, such as low socioeconomic status (SES), a large family, or single motherhood (Egle, Hoffmann,
& Steffens, 1997), and low parental education (Karvonen et al., 2005; Piko &
Fitzpatrick, 2007; Sleskova et al., 2006). Unemployment of either mother or
father has also been identified as a risk factor for child health (Sleskova et al.,
2006), whereby economic stress, rather than social class, was a significant
determinant of psychosomatic complaints (Östberg et al., 2006). Still, Torsheim
and colleagues (2004) found a uniform pattern between health and social
inequalities across 22 countries, suggesting that previous inconsistent findings may in part be an artifact of methodological variance.
National Indicators
Research on children and adolescents which included national indicators has
found that both low household income and high material inequalities are
associated with poorer subjective health (Torsheim et al., 2006). Holstein
and colleagues (2009) found a relationship between material inequality
(measured by the Gini coefficient) and psychosomatic complaints, but not
for gross national product (GNP). In contrast, Olsen and Dahl (2007) did not
find a significant relationship between the Gini coefficient and health but
found one for gross domestic product (GDP). Another study comparing psy-

chosomatic complaints in children in five Scandinavian countries revealed
largest country differences at the macro level, that is, economic factors, SES,
and economic resources of family (Berntsson et al., 2001). Interestingly,
despite variations in unemployment rates between the countries, there were
no notable country differences in the associations between psychosomatic
complaints, SES, family economy, and family type, indicating multidimensional risk factors for psychosomatic complaints and a complex relationship
between macro-level factors and individual health. A useful alternative to
traditional measures of development, such as GDP which only reflects one
dimension, is the Human Development Index (HDI) which covers the following dimensions: knowledge, healthy life, and standard of living (Sagar &
Najam, 1998). While a vast majority of research papers on child health have
used GDP (or GNP) and/or the Gini coefficient as indicators, none of them
has used the Human Development Index (HDI).
Research Aims
The purpose of this article was to extend previous research on psychosomatic
complaints from a stress perspective by investigating social stress factors at
an individual and a national (societal) level using a large international sample of young adolescents. The individual-level stress factors included familial factors (family structure, communication with parents), peer relations
(bullying, number of close friends), and school context (class climate, academic achievement). Physical activity and sedentary behaviors (media use)
were also included in the analyses to control for the effect of health behaviors. In addition, country-level effects were taken into account to further
understand the potential relationship between national factors and psychosomatic complaints. Based on previous research outlined above, we chose to
use HDI to analyze country-level effects as this multidimensional index
covers three relevant dimensions (healthy life, education, and economic
aspects) which are measured via life expectancy, adult literacy, and GDP. It
is a broad measure of national well-being (Moon, Welch, & Wong, 2005).
Currently, a majority of the studies on psychosomatic complaints and
stress come from Scandinavian countries (Eriksson & Sellström, 2010; Hjern
et al., 2008; Sundblad et al., 2008; Torsheim & Wold, 2001). Relatively little
is known about cross-national differences, in particular, on the combined
effects of individual- and country-level factors on psychosomatic complaints.
On this background, the following hypotheses were formulated and tested.

Ottova et al.
Hypothesis 1: Stable family structure and easy communication with
parents is associated with lower rates of psychosomatic complaints
(i.e., better health).
Hypothesis 2: Good peer relationships (high number of close friends,
no or low occurrence of bullying) are associated with lower rates of
psychosomatic complaints (i.e., better health).
Hypothesis 3: A positive class climate and low pressure at school are
associated with lower rates of psychosomatic complaints (i.e., better
health).
Hypothesis 4: A high HDI is associated with a higher average level of
psychosomatic health in a country.
Method
Participants
The sample used in this study was obtained from the 2005/2006 HBSC
study. The HBSC study is an international survey conducted every 4 years in
a growing number of countries. Data were collected through a school-based
survey using classroom-administered self-completion questionnaires in each
participating country and region. Data collection and questionnaires were
based on a standardized research protocol. Participation in the survey was
voluntary, and assurance was provided in relation to confidentiality and anonymity. Each country was required to respect the ethical and legal requirements in their country for this type of survey. The target populations for the
study were 11-, 13- and 15-year-old children (Grades 5, 7, and 9). Participating
countries were required to include a minimum of 95% of the eligible target
population within their sample frame. The samples were drawn using the
cluster sampling procedure, whereby the primary sampling unit was school
class. The final international file contained 204,534 pupils across 41 countries or regions, consisting of 100,233 (49%) boys and 104,301 (51%) girls,
and 66,707 (33%) 11-year-olds, 69,954 (34%) 13-year-olds, and 67,873
(33%) 15-year-olds. The sampling response rates for all the countries in the
2005/2006 HBSC study ranged from 47% to 100% for school/class level and
from 34% to 97% at the pupil level. In most countries, school/class- and
pupil-level response rates were above 70% (Roberts et al., 2009). Full details
on the study and the participants can be found elsewhere (Currie et al., 2008a;
Roberts et al., 2007, 2009).
The present study included data from 98,773 11- and 13-year-olds from 34
countries. Due to lack of data on some covariates, Israel, Malta, Slovakia, and

the United States were excluded from the analyses. In addition, we excluded
Greenland, Scotland, and Wales due to lack of information on HDI. We
focused on 11- and 13-year-olds to capture the transition from childhood to
adolescence, when youth are most likely to be susceptible to social stressors.
Hence, analyses for the present study were based on 98,773 adolescents.
Instruments
Psychosomatic complaints. In the HBSC study, the HBSC symptom checklist
(HBSC-SCL) was used to assess the occurrence of psychosomatic health complaints (Haugland et al., 2001). The HBSC-SCL is a reliable and valid instrument (Ravens-Sieberer et al., 2008) which measures eight symptoms (headache,
stomach ache, back ache, feeling low, irritability or bad temper, feeling nervous, difficulties in falling asleep, and feeling dizzy) during the past 6 months.
Answers were rated on a 5-point scale ranging from about every day to rarely
or never. Although previous research has suggested a two-factor solution, the
scale can also be thought to measure a unidimensional latent trait of psychosomatic complaints (Ravens-Sieberer et al., 2008). Multiple recurrent psychosomatic complaints were defined as at least two symptoms occurring more than
once weekly (Cronbach’s α = .80).
Physical activity and sedentary behaviors. Measures of physical activity and
sedentary behavior were included in the analysis. “Moderate to vigorous”
physical activity was assessed using the measure developed by Prochaska,
Sallis, & Long (2001). The valid and reliable measure asks the question: “Over
the past 7 days, on how many days were you physically active for a total of at
least 60 minutes per day?” with answer options ranging from 0 days to 7 days.
Information on sedentary behavior was assessed by asking how often respondents watched TV (including DVDs and videos), used the computer (for chatting online, Internet, emailing, homework, etc.), and played computer games
on weekdays and on weekends. The answer options were “not at all,” “about
half an hour a day,” “about 1 hour a day,” [. . .], “about 7 or more hours a day.”
Although results from a validation study on the HBSC items are not available,
a study by Schmitz et al. (2004) found high reliability and validity for similar
type of items with similar age groups. For this analysis, an index was calculated by averaging the responses for all three areas (TV watching, computer
use, and computer games) for weekdays and for weekend. This will be referred
to as the Media Use Index (Cronbach’s α = .59).
Familial context. The family context was assessed by two measures: communication with parents and family structure. The first asked “How easy is it
for you to talk to the following persons about things that really bother you?”
Downloaded from jea.sagepub.com at NUI, Galway on June 12, 2012
135
Ottova et al.
with option responses of “very easy,” “easy,” “difficult,” “very difficult,” or
“don’t have or see this person.” Separate questions were used for mother and
father. The item responses were dichotomized into “very easy/easy/don’t
have or see this person” and “difficult/very difficult.” Family structure was
assessed by asking adolescents to indicate who else usually lives with them
at home, also including whether they had siblings living with them and, if
yes, how many. In the analysis, we differentiated between families with “both
parents,” “single parent,” “step family,” or “other.” The number of female
and male siblings was combined for analysis. Both parental communication
and family structure are measures which were developed within HBSC.
Peer relations. Peer relations were assessed through two measures: number
of close friends and experience of bullying. The first was assessed by “At present, how many close male and female friends do you have?” with response
options of “none,” “one,” “two,” and “three or more.” Respondents answered
the question for each gender separately. Answers were later combined and the
average number of male and female friends calculated. Negative peer relations
were measured by asking “How often have you been bullied at school in the
past couple of months?” The answer options were “I have not been bullied at
school in the past couple of months,” “it has only happened once or twice,” “2
or 3 times a month,” “about once a week,” or “several times a week.” The
answer categories were dichotomized into “2 or 3 times a month/about once a
week/several times a week” versus “it has only happened once or twice/I have
not been bullied at school in the past couple of months.” The measure is based
on an adapted version developed by Olweus (1996).
School environment. School-related factors included class climate and
potential stressors at school (academic achievement and workload), all of
which have been developed within the HBSC study. Student relations were
measured by three items and a validation study has shown that these three
items function well as a subscale of a valid measurement model on support
(Osen, Torsheim, & Wold, 2000; Torsheim, Wold, & Samdal, 2000). The
items ask the participants to rate how much they agreed or disagreed with
each of three statements about students in their classes. The statements were
“students like being together,” “students are kind and helpful,” and “students
accept me.” Answers were rated on a 5-point scale ranging from strongly
agree to strongly disagree. The Class Climate Index used in the analyses was
calculated as the mean of the three items (Cronbach’s α = .70). Academic
achievement was assessed by the question “In your opinion, what does your
class teacher(s) think about your school performance compared to your classmates?” The response categories were “very good,” “good,” “average,” or
“below average.” Workload pressure was assessed by the question “How
Downloaded from jea.sagepub.com at NUI, Galway on June 12, 2012
136
Journal of Early Adolescence 32(1)
pressured do you feel by the schoolwork you have to do?” The answer options
were “not at all,” “a little,” “some,” or “a lot.” The School Pressure Index was
calculated in the same manner as the Class Climate Index.
Socioeconomic factors. The SES of the family was measured by the Family
Affluence Scale (FAS) which was based on four items: “Does your family
own a car, van, or truck?” (0 = no, 1 = yes, one, 2 = yes, two or more), “Do
you have your own bedroom for yourself?” (0 = no, 1 = yes), “During the past
12 months, how many times did you travel away on holiday [vacation] with
your family?” (0 = not at all, 1 = once, 2 = twice, 2 = more than twice), and
“How many computers does your family own?” (0 = none, 1 = one, 2 = two,
2 = more than two). The scores of the answers were summed (range 0-7), and
individuals were categorized into high (6-7), medium (4-5), and low (0-3) FAS
groups (Currie et al., 2008b). The FAS has been validated and can be used as
“an indicator of child material affluence” (Currie et al., 2008b, p. 1433).
Country-level indicators. The HDI was developed by the United Nations
Development Program (UNDP) and is a composite index formed by three
components: longevity, education, and income. Despite criticism of the construct (Neumayer, 2001; Sagar & Najam, 1998), it has proven to be a valid
index (Noorbakhsh, 1998). Information on the HDI was obtained from the
UNDP website at http://hdrstats.undp.org/en/indicators/.
Statistical Analyses
Linear multilevel regression analyses were performed using HLM 5.05 software. Multilevel analyses account for the fact that responders within a certain context (e.g., country) may be more similar to each other than to
individuals from a different context (i.e., intracontext correlation). As the
variability of effects across different contexts was estimated, the role of contextual factors for this variability could be studied.
To account for the hierarchical and clustered structure of the data, a hierarchical two-level model including separate variances at the individual level
and at the country level (second level) was specified with random variation
of the intercepts and slopes across countries. The reliability of the crosscountry variation was examined first, and an intraclass correlation coefficient
greater than .10 indicates that 10% of the observed variation in the coefficients between countries represents a “true” difference (Cheung & Keeves,
1990). Such coefficients (intercepts and slopes) were specified as “random”
and the coefficients and their distributions of variation across countries were
estimated. The variance partitioning coefficient denotes the proportion of
“reliable” variance in the outcome that is attributable to country differences.

Consistent with Cohen’s recommendations, a proportion of .14 or greater
was classified as a large effect (Cohen, 1988).
Ravens-Sieberer et al. (2008) developed a unidimensional scoring algorithm based on seven of the eight items of the HBSC-SCL which enables
valid cross-cultural comparisons and interval-scaled assessment of subjective
health complaints. In this study, sociodemographic, socioeconomic, and
familial-, school- and peer-related covariates were regressed on the psychosomatic sum score (see Appendix A for details on the formulae). The random
variation of the intercept was regressed on HDI. The analyses were repeated
for multiple recurrent health complaints using multilevel logistic regression
analysis. Odds ratios (OR) were computed and are presented.
Where possible, we tested the assumptions for hierarchical linear modelling empirically (linear relationship, distribution of residuals, equal variances, and covariances; Ditton, 1998). The other assumptions were considered
from theoretical considerations of the model specifications. To the best of our
knowledge, these assumptions were not violated.
Results
Table 1 presents descriptive results of the total sample for the dependent
variable (psychosomatic complaints) as well as for some of the independent
variables (gender, family structure, communication with parents, FAS, being
bullied) including the HDI. The results for the remaining variables are presented in Appendix B. Girls comprised 52% of the total sample analyzed and
there were slightly fewer 11-year-olds (48%) than 13-year-olds (52%). The
mean age of the sample was 12.64 (SD = 1.05).
The intercept and slopes were estimated as random effects across the
countries. The intercept for the country-level indicator, age, and media use
were regressed on the HDI. The variance partitioning coefficient of the
dependent variable in the null model was .771.
A mean psychosomatic complaint value of 4.09 was observed in our sample. Statistically significant differences were seen in the average number of
psychosomatic complaints reported between different countries. The unconditional model with random intercept across country explained 4.33% of the
overall variance. Cross-country variation in the intercept accounted for
6.14% of the overall variance in psychosomatic complaints. It was estimated
that for 95% of the comparable countries, the mean number of psychosomatic
complaints is within the range of 3.74 to 4.44. The full final model explained
23.67% of the overall variance. The prevalence of young adolescents reporting multiple recurrent psychosomatic complaints (two or more complaints
more than once a week) varied between 17% (Austria) and 64% (Turkey).

Table 2 shows that a higher age, being a girl, not living with two original
parents (i.e., living with a single parent, step parent, or other parent), lack of
easy communication with one’s father or mother, low FAS, and high media
use were each associated with more psychosomatic complaints. Regarding
the school domain, a negative class climate, higher school pressure, and having been bullied two to three times or more in the past couple of months were
associated with more psychosomatic complaints.
Statistically significant interactions with gender were observed for the
Close Friends Index, the Class Climate Index, the School Pressure Index, and
the Media Use Index. Without consideration of interactions, girls have a
fixed effect coefficient of -.129, t(33) = 4.41, p < .001. When interaction
terms are entered into the model, the decreasing effects of poor close friends
relationships (-.012 [t(33) = -2.23, p = .033]), a negative class climate (-.031
[t(33) = -5.34, p < .001]), high school pressure (-.087 [t(33) = -11.25, p <
.001]), and a high media use (-.019 [t(33) = -4.99, p < .001]) on psychosomatic health were more pronounced for girls (indicated by negative interaction coefficients) which add to the decreasing effects of these predictors.
The results further show an association between cross-country variation and
HDI, wherein an increase of 0.1 HDI points was associated with an increase of
0.12 points on the Psychosomatic Complaints Index (indicating better health).
Moreover, we tested if the individual-level predictors contribute to individual psychosomatic health in the same way for countries with different
HDI. Within the multilevel regression model, it was tested if the cross-country
variability in individual-level predictors could be explained by HDI. Results
showed a significant covariation of individual-level coefficients with HDI
only for age and media use. The decreasing effect of higher age (-.017
[t(32) = -4.80, p < .01]) was less pronounced in countries with high HDI (age
on HDI: 0.131 [t(32) = 2.64, p < .05]). The decreasing effect of media use
(-.037 [t(32) = -16.41, p < .01]) on the other hand was more pronounced in
countries with high HDI (media use on HDI: -.163 [t(32) = -6.07, p < .001]).
Table 3 shows the results of the multilevel logistic regression of the effect
of the covariates shown in Table 2 on multiple recurrent psychosomatic complaints (at least two symptoms more than once a week).
Being a girl, not living with two original parents (i.e., living with a single
parent, step parent, or other parents), communication with father or mother
not being easy, low FAS, and high media use were all associated with an
increased risk (OR) of multiple recurrent health complaints. In the school
context, negative class climate, school pressure, and having been bullied 2 to
3 times or more in the past couple of months were also associated with an
increased risk of multiple recurrent health complaints. Frequent physical

activity was associated with a lower risk for multiple recurrent health complaints (OR = 0.98, p < .001).
The risk for multiple recurrent health complaints associated with a poor
Close Friends Index (OR = 1.02, p = .331), negative class climate (OR = 1.05,
p < .01), high school pressure (OR = 1.12, p < .001), and high media use (OR =
1.02, p = .066) was more pronounced for girls as indicated by the additional
OR for the interaction terms.
A statistically significant cross-national variability was observed in the
percentage of young adolescents suffering from multiple recurrent health
complaints. This cross-national variability was associated with the HDI, and
a higher HDI was associated with a lower risk for multiple recurrent health
complaints.
Finally, we also tested if the inclusion of the control variables (physical
activity and Media Use Index) affected the estimation of the other coefficients, but we only found marginal differences.
Discussion
The purpose of this study was to investigate the relationship between both
individual-level (family, peers, school) and country-level factors with psychosomatic complaints in a large international sample of young adolescents. We
found that not living with both original parents, having difficulty talking with
either parent, being bullied 2 to 3 times or more in the past couple of months,
and experiencing high academic pressure at school was associated with poorer
psychosomatic health and a higher chance for multiple recurrent psychosomatic complaints. The next section will begin by addressing the hypotheses
formulated in the introduction and connecting these to the results found in this
study. Following a discussion of the main findings in light of past research in
this field, strengths and limitations of this study will be pointed out. The discussion concludes with implications for policy and practice.
As hypothesized, a stable family structure, good communication with
one’s parents, good peer relationships, absence of negative social interactions
(bullying), and a positive school environment (good class climate, low
schoolwork pressure) were all associated with better psychosomatic health.
At the country level, a positive relationship between HDI and young people’s psychosomatic health emerged as well as significant covariation
between the HDI and age, and between HDI and media use. Specifically,
decreasing effects of higher age were less pronounced in countries with
high HDI, while, for media use, the opposite was true. Our results

confirmed the fourth hypothesis showing that countries with a high HDI
score had generally lower rates of psychosomatic complaints. By testing a
multidimensional country-level indicator—HDI—in a multinational data
set, our study makes an important contribution to research on young adolescents’ psychosomatic health.
From the stress perspective, psychosomatic complaints are heightened by
experiences that induce stress and are possibly relieved by protective factors.
In general, our results showed that most of the variance in psychosomatic
complaints was due to individual-level stressors found in all investigated
domains (family, peers, school) as well as the larger socioeconomic context.
These findings are consistent with other studies that also stressed the importance of family structure and child-parental relationships during adolescence
(Brolin Laftman & Östberg, 2006; Due, Lynch, Holstein, & Modvig, 2003).
Surprisingly, positive social relations did not have a significant effect in this
study, although previous research has shown that the quality of friendships
and supportive relationships are important for adolescent well-being (Rubin
et al., 2004). Negative peer relationships however did have an impact: adolescents who were frequently bullied were more likely to report multiple
recurrent psychosomatic complaints than those who were not bullied. This
negative effect of bullying on individual well-being is consistent with other
studies on this subject (Alfven, Őstberg, & Hjern, 2008; Ghandour et al.,
2004; Richter et al., 2007).
Consistent with previous studies, negative class climate and school pressure were both significantly associated with psychosomatic complaints
(Torsheim & Wold, 2001). Too much pressure from schoolwork can have a
negative effect, especially if there is too little free time to relax and participate in activities that benefit well-being (Gaspar, 2010). Consistent with previous research, being a girl was associated with a higher risk for psychosomatic
complaints (Cavallo et al., 2006). Different socialization strategies, as well as
higher attentiveness to their body (Verbruggev, 1982), may explain some of
the gender differences in complaint or symptom reporting. In fact, in many
cultures, the expression of physical and emotional states is more acceptable
for girls than for boys (Gijbers van Wijk, van Vilet, Kolk, & Everaerd, 1991).
In this study, age did not have significant effects, but this could be due to the
narrow age span under investigation (11- and 13-year-olds only).
After controlling for individual-level factors, an effect of national characteristics (HDI) still remained. This demonstrates that individual psychosomatic complaints are also predicted by the social state of one’s country.

complaints even after controlling for other stressors. Previous research on
this subject has shown the effect of certain country-level indicators, such as
the Gini and GDP (Holstein et al., 2009; Olsen & Dahl, 2007; Torsheim et
al., 2006). In this study, we looked at the effect of the HDI to see whether it
would explain more of the variance in the cross-national differences in psychosomatic complaints. Indeed, an effect of HDI was identified, and our
results further show that the decreasing effect of higher age on psychosomatic complaints was lower in countries with a high HDI, whereas high
media use had a greater decreasing effect on psychosomatic complaints in
countries with a high HDI. Thus, as adolescents get older, they tend to
experience more psychosomatic complaints, but this effect is most pronounced in countries with low HDI. We may only speculate why this is the
case. Perhaps, the effect of living in a low-HDI country is felt most by older
adolescents as they tend to be more aware of the social and socioeconomic
context in which they live. With regard to media use, the effect we found
may be due to another third variable which is related to HDI and psychosomatic complaints.
The prevalence of psychosomatic complaints varied greatly between
countries, whereby it was lowest in Austria (17%) and highest in Turkey
(64%). The reason for these differences is not clear but it can be assumed that
cultural issues play a part—an aspect that could be clarified by further qualitative research. Although psychosomatic complaints occur in all cultures, not
all cultures may be accepting of psychological symptoms and mental illness
(Araya, Rojas, Fritsch, Acuna, & Lewis, 2001). Cultural factors may influence the way a somatic complaint is described, expressed, and categorized.
The key difference is the nature of the social adversities and the types of illness models that might predispose individuals to or precipitate these complaints (Patel & Sumathipala, 2006). The HBSC-SCL is sensitive to cross-cultural
comparisons, and previous analyses have identified cross-cultural variations in psychosomatic complaints among 35 countries (Ravens-Sieberer
et al., 2008).
Strengths and Limitations
This study has several strengths that deserve attention. First, we used data
from a large international survey (HBSC) that is carried out every 4 years
and provides valuable information on health status and health behavior in a
large sample of children. Second, obtaining data from children themselves
through self report is advantageous when exploring subjective constructs
Downloaded from jea.sagepub.com at NUI, Galway on June 12, 2012
146
Journal of Early Adolescence 32(1)
such as well-being. Third, country-level indicators such as HDI have been
rarely used in cross-sectional analyses and can be useful in further explaining
cross-country patterns. We consider the use of the HDI a strength of this
study as it introduces an innovative aspect in research on child health. Even
though it has been criticized (McGillivray, 1991), it adds a different perspective in the interpretation of country differences as it measures human development along three dimensions (knowledge, healthy life, standard of living;
Sagar & Najam, 1998). In this way, it broadens the discussion and contributes to research.
At the same time, there are also some limitations that need to be stressed.
The use of single-item scales for capturing various health behaviors (e.g.,
physical activity, sedentary behavior), as well as for the other contexts (family, school, peers), posed some challenges. Generally, multiple item measures are preferred as they are more reliable and this is important in statistical
analyses when errors of variance need to be minimized (Loo, 2002). However,
most of the single-item measures have long-standing use in HBSC and many
have been subjected to validation studies (Prochaska et al., 2001). The crosssectional nature of HBSC prohibits any conclusions about causal relationships. Last, we did not control for chronic diseases or for emotional disturbances
(such as anxiety, depressive mood). Although most of the complaints during
adolescence have no organic cause (Taylor, Szatmari, Boyle, & Offord,
1996), lack of information on chronic diseases and emotional disturbances,
both of which have somatic and emotional correlates, may be considered a
weakness. Chronic disease may be a stressor in itself (Compas & Boyer,
2001) and thus could have an indirect effect on complaints.
Implications of the Findings and Future Directions
Given the fact that psychosomatic complaints are higher in girls and are
associated with the HDI of a country, one implication of this study is that
gender-specific health promotion programs should be adapted to the cultural
context within each country. The availability and use of media should be
taken into greater consideration in programs targeting health behavior modifications as media use emerged as an important factor associated with health
complaints—particularly in girls—and moreover had a more negative effect
in countries with high HDI. Thus, programs in countries with higher HDI
should take media use into greater account.
