In addition, sex differences in the approach and avoidance goals were examined as well as goal contrast scores (i.e., approach minus avoidance) as secondary purposes. Design: The research was cross-sectional in design. Method: Participants were 804 university students who completed a questionnaire assessing their stage of physical activity, 2 2 achievement goals, and demographics. Results: MANOVA results revealed hypothesized and significant (p < .001) physical activity stage differences in the mastery and performance approach goals as well as significant (p’s < .05) gender differences in both performance goals. A significant (p < .01) gender by physical activity stage interaction emerged for the performance goals and surprisingly, was found mainly in the advanced exercise stages (i.e., action, maintenance, and long-term maintenance). Last, significant (p < .001) gender and physical activity stage main effects emerged for the achievement goal contrasts. Males endorsed both the mastery and performance contrasts more than females. Collapsed for both sexes, the contrast scores were greater in the physically active than the non-active stages. Conclusions: Findings suggested that interventions targeting physical activity in university students should emphasize approach goals relative to the avoidance goals. Particular attention should be paid to the performance goals in the maintenance and long-term maintenance stages as they appeared theoretically inconsistent for the female participants. Last, the split in the preparation stage (active, nonactive) should be incorporated into future stage based investigations as the split demonstrated two meaningfully different subgroups.

Keywords: Physical activity stages Physical activity Achievement goals Gender Goal contrasts Increasing leisure time physical activity is a U.S. national priority as approximately 25% of adults report engaging in no form of leisure-time physical activity (Centers for Disease Control and Prevention, 2010). Consequences of this lack of leisure-time physical activity range from increased risk of cancers, depression, cardiovascular disease, and overweight to obesity (Warburton, Nicol, & Bredin, 2006). Consequently, an understanding of leisure time physical activity determinants is of great importance. Several * Corresponding author. Tel.: þ1 806 742 3371; fax: þ1 806 742 1688.

For example, social cognitive approaches, self-determination theory, and stage models have had some success; and likewise, physical activity interventions following these approaches have shown some promise (Bauman, Sallis, Dzewaltowski, & Owen, 2002). Yet, given the continual high rates of physical inactivity and related consequences such as the obesity epidemic, more research is needed. The achievement goal approach (e.g., Dweck & Leggett, 1988; Elliot, 1999; Nicholls, 1989) has demonstrated efficacy in predicting salient sport and exercise outcomes such as emotions, intrinsic motivation, and self-regulation of behaviors (see Roberts, Treasure, & Conroy, 2007 for a review). Research utilizing achievement goal theory has shown promise in understanding physical activity, but is relatively understudied with respect to Author's personal copy 162 M. Lochbaum et al. / Psychology of Sport and Exercise 14 (2013) 161e168 Elliot’s (1999) contemporary 2 2 framework. Hence, the main purpose of the present investigation was to examine the relationship of the contemporary 2 2 achievement goal framework to stages of physical activity participation in a large sample of university students. Achievement goal frameworks Historically, the dichotomous achievement goal approach has been concerned with an individual’s subjective interpretation of success corresponding to the task (mastery) and ego (performance) oriented achievement goals (e.g., Dweck & Leggett, 1988; Nicholls, 1989). A task oriented individual’s action is primarily motivated by personal mastery or improvement, and as such, reflects a selfreferenced standard of personal achievement. Conversely, an egooriented person strives to win and is motivated to attain high normative standards of ability. Ego-oriented individuals judge success and failure on other-referenced standards and are motivationally “fragile” when they doubt their own competence (Roberts et al., 2007). Adding to the task/ego distinction, Elliot et al. (Elliot, 1997; Elliot, 1999; Elliot & Church, 1997; Elliot & Harackiewicz, 1996) proposed that an approach-avoidance goal dimension should be included in the dichotomous goal framework. While the task/ego distinction relates to how competence is defined, the approach-avoidance dimension relates to how competence is valenced. An approach valence indicates a behavior that is initiated by a positive or desirable event or possibility. In contrast, an avoidance valence indicates a behavior which is initiated by a negative or undesirable event or possibility (Elliot, 1999; Elliot & Church, 1997). Thus, approach goals focus on attaining competence, whereas avoidance goals focus on avoiding incompetence. Based on the valence and definition of achievement goals, (Conroy & Elliot, 2004; Elliot, 1999; Elliot & Thrash, 2001, 2002) established the following 2 2 achievement goal framework: the mastery-approach, masteryavoidance, performance-approach, and performance-avoidance goals. The mastery-approach goal is defined by a focus on taskbased attainment. The behavior of going to work-out would be initiated by seeing the work-out as a desirable event. The masteryavoidance goal is defined by a focus on avoiding a worsening of task-based attainment. The behavior of missing a work-out would be initiated by the perception that going to work-out was an undesirable event, given the likelihood of performing less vigorous exercise than usual as a result of fatigue or other personal factors. Research has demonstrated that the mastery-approach goal is strongly and positively related to intrinsically motivating thoughts and or self-determined exercise motivation (Moreno, GonzalesCutre, Sicilia, & Spray, 2010; Nien & Duda, 2008; Wang, Liu, Lochbaum, & Stevenson, 2009), whereas the mastery-avoidance is related to physical activity amotivation (i.e., antipathy; Nien & Duda, 2008). From the performance goal perspective, the performanceapproach goal defines competence based on normative achievements. Thus, engaging in a regimen of upper body strength training over a given time period to achieve a desired normative based fitness standard such as the “good” standard for maximal push-ups is an example of a performance-approach initiated behavior (the upper body strength training regimen). In contrast, the performance-avoidance goal defines competence based on avoiding displays of normative incompetence. An individual with a strong performance-avoidance goal might simply avoid performing normative based fitness tests as a competence protective mechanism. It is also theoretically possible that a strong performance-avoidance goal endorsement could lead one to engage in non-normative forms of exercise (e.g., going for a walk by oneself) if the outcome in question was not getting worse on a normative standard in front of others. Thus, if someone knew in advance of a public fitness display such as group fitness testing, that individual might engage in upper body strength training to avoid being in a less than desirable normative category. Research has demonstrated however, that the performance-avoidance goal is inversely related to self-determined motivation (Moreno et al., 2010) and positively related to amotivation for physical activity (Nien & Duda, 2008). Achievement goals and leisure time exercise The 2 2 achievement goal and leisure time physical activity research base is relatively small. Nonetheless, existing studies provide a base for the present investigation (Lochbaum, Stevenson, & Hilario, 2009; Skjesol & Halvari, 2005; Wang, Biddle, & Elliot, 2007). For instance, Lochbaum et al. (2009) reported correlations between the 2 2 achievement goals and self-reported strenuous exercise involvement in a university sample. For the males (n ¼ 155), significant correlations for the mastery (r ¼ .27) and performanceapproach goals (r ¼ .24) emerged. For the females, only the relationship between mastery-approach goals and strenuous exercise was significant, albeit relatively small in magnitude (r ¼ .17). Skjesol and Halvari (2005) in a sample of 188 Norwegian secondary students reported marked differences in Spearman’s point-biseral coefficients between performance goals and physical activity involvement (.35 for approach compared to .07 for avoidance). Last, Wang et al. (2007) in a younger adolescent sample from Singapore reported stronger correlations with a self-reported measure of physical activity outside of school physical education for approach goals (r’s ¼ .30 and .22, for mastery and performance) compared to avoidance goals (r’s ¼ .10 and .09, for mastery and performance). Thus, overall with measures of physical activity in three different aged samples of different nationalities, findings appear to suggest that both mastery-approach and performance-approach goals are positively related to self-reported physical activity. With the appetitive nature inherent in both approach goals, these relationships with physical activity, a motivated behavior, appear theoretically correct. Further research is clearly needed however, to examine whether avoidance goals are related to physical activity behaviors as the literature base to date is relatively small though promising. Stages of behavior change The present study sought to explore patterns of Elliot’s approach-avoidance achievement goals across a number of stages of physical activity. The various stages of physical activity participation were based on the transtheoretical model stage of change approach (Prochaska & DiClemente, 1983) and the Centers for Disease Control and Prevention (CDC) recommendations for what constitutes acceptable physical activity participation (Centers for Disease Control and Prevention, 2010). The stage approach was chosen because of the possible advantages of the stage continuum that separates decisional, implementation, and behavioral actions from one another (Prochaska & DiClemente, 1983; Prochaska & Velicer, 1997; Weinstein, Lyon, Sandman, & Cuite, 1988). The stage model describes the different phases involved in the adoption and eventual maintenance of a behavior, in the case of the present study, exercise behavior. The six phases of the stage model are precontemplation, contemplation, preparation, action, maintenance, and termination. In the pre-contemplation stage, there is no intention to change a behavior. In the contemplation stage, the individual recognizes that their current behavior is problematic and assesses the pros and cons of their continued actions or inaction. The other stages are preparation, whereby the behavior has not Author's personal copy M. Lochbaum et al. / Psychology of Sport and Exercise 14 (2013) 161e168 been sustained but is hoped to begin in consistency in a month; action, whereby the behavior has been sustained for up to six months; maintenance, whereby the behavior has been sustained from six months to five years; and finally, termination where the behavior has been sustained for at least five years. Based on data in the literature (Nishida, Suzuki, Wang, & Kira, 2004) and anecdotal evidence from the first author’s experiences with college aged students, the preparation stage was split into two distinct phases (see Methods section) as it seemed that meaningful differences in the achievement goals could exist between “less active” and “more active” preparation stage participants. It is reasonable to assume that even within the preparation stage, a number of participants could be very close to meeting recommended guidelines (i.e., play a variety of intramural sports during the week, lift weights with friends from time to time) for physical activity, while others are merely thinking about initiating exercise. In addition to this modification given the stage approach was initially concerned with the elimination of undesirable health behaviors such as drug use, termination was the appropriate label, but for engagement in a desired behavior such as physical activity it seemed inappropriate. Hence, the “termination” stage was labeled “longterm maintenance” in the present investigation. Investigations have demonstrated the efficacy of the stage of change model in understanding how important thought patterns (e.g., Prochaska & Velicer, 1997) or personalities (e.g., Lochbaum et al., 2010) may differ depending upon one’s stage of physical activity or exercise behavior. Study purposes and hypotheses Based on Elliot’s work and the reviewed research with approachavoidance achievement goals and physical activity, four hypotheses were tested. First, it was hypothesized (HO1) that both approach goals e mastery and performance e would be more characteristic of the advanced exercise stages (i.e., action, maintenance, long-term maintenance) compared to the lower stages. Given the appetitive nature of both approach goals it seemed logical that they would be associated with more sustained, personally endorsed exercise behaviors, characteristic of the advanced stages. Our second hypothesis (HO2) was that the avoidance based goals would be more characteristic of the lower stages (i.e., non-exercising). Given the aversive nature of avoidance goals (i.e., individuals display an antipathy toward demonstrations of incompetence), it seemed reasonable that they would be associated with the tendency toward no or infrequent intentional physical activity. Two further purposes were also explored. The third hypothesis (HO3) was related to Elliot’s (1999) hypothesis that gender is an antecedent of achievement goal adoption. Specifically, he posited, based on past avoidance motivation research, that females (e.g., Markus, Kitayama, & Heimen, 1996; Stein & Bailey, 1973) would be more likely to endorse a performance-avoidance goal orientation. Given that Elliot’s mastery-avoidance constructs were advanced after his 1999 publication, no hypotheses have been forwarded concerning potential gender differences with regard to the mastery-avoidance goal. To date, few investigations have reported intentional tests of Elliot’s hypothesis in the sport and exercise psychology literature. A few studies with comparable samples do exist (e.g., university students). Using 230 university athletes, Morris and Kavussanu (2008) investigated several antecedents to the approach-avoidance achievement goals and reported that gender was a significant predictor of the mastery-avoidance goal with females being higher in this goal. Nien and Duda (2008) investigated antecedents and consequences to the approachavoidance achievement goals in 450 university and club sport athletes. An examination of their reported approach-avoidance achievement goals by gender indicated that females endorsed the 163 mastery-avoidance goal more so than males though no differences existed for the performance-avoidance goal. Thus, Elliot’s hypothesized gender differences in the performance-avoidance goal seem to have little support, but evidence exists concerning females being higher in the mastery-avoidance goal. In summary, it was tentatively hypothesized that females would score higher on both avoidance goals compared to their male counterparts collapsed across all physical activity stages. The final hypothesis (HO4a and HO4b), examined goal contrast scores. In sport research, the performance goal contrast (i.e., standardized performance-approach score minus standardized performance-avoidance score) has demonstrated efficacy in predicting youth basketball dribbling performance (Elliot, Cury, Fryer, & Huguet, 2006), triathlon performance (Stoeber, Uphill, & Hothman, 2009), and track and field performance (Stoeber & Crombie, 2010). In these investigations, the contrast score has been more predictive of performances when compared to either performance goals. Similarly, in the present investigation such scores provided the opportunity to gain further insight into whether participants in the lower exercise stages would have on average higher avoidance than approach scores or whether those in the latter exercise stages would have on average higher approach than avoidance goals. It was hypothesized (HO4a) that the contrast score would increase (performance-approach > performanceavoidance) across the physical activity stages. In addition, given the consistent relationship between the mastery-approach goal and leisure time physical activity, it may as well be that a mastery contrast score is more characteristic of the advanced exercise stages (HO4b). This relationship appears logical as personal improvement is certainly an aspect of consistent, long term physical activity involvement. Therefore, the mastery contrast/physical activity stage pattern was also examined. Method Participants Participants were 804 college age students from a large southwestern university enrolled in a variety of 1-h fitness and wellness classes (377 women and 391 men). Enrollment in the courses is a partial requirement for graduation from one of the colleges within the southwestern university, though the courses may be taken by all students. Mean ages of the participants were 20.88 2.67 and 21.51 2.12 for women and men, respectively. Participation was voluntary. Participants identified themselves as Caucasian, 71.51%, Hispanic, 19.02%, African-American, 5.34%, Asian American, 2.36%, and American Indian, 1.36%. Concerning physical activity stage, participants identified themselves across the contemplation to long-term maintenance stages (see Table 1). No participant identified him or herself in the pre-contemplation stage. Given the sample was college aged students, the lack of participants identifying themselves in the pre-contemplation stage (i.e., no intention of becoming an exerciser) was encouraging. Instruments Participants were provided a packet assessing demographic information (i.e., age, gender, and ethnicity), exercise stage, and achievement goals. Exercise stage The exercise stage measure was comprised of seven sentences that described an individual’s current situation in regard to exercise participation and was adapted from several past investigations (e.g., Courneya, 1995; Lochbaum et al., 2010; Nishida et al., 2004) all Author's personal copy 164 M.

In these past investigations, the participants were queried concerning regular exercise participation, defined as activity completed at least three times per week, for at least 20e30 min in duration. In the present investigation, participants were queried with the more contemporary Center for Disease Control and Prevention’s “Physical Activity for Everyone” definition of sufficient leisure time exercise for health benefits: 150 min of moderate aerobic activity per week and two days of muscle-strengthening activities or 75 min of strenuous aerobic activity per week and two days of muscle-strengthening or an equivalent combination of strenuous and moderate aerobic activity and two days of muscle-strengthening activities. The moderate and vigorous intensity definitions include a wide variety of physical activities including sports. Participants were asked to circle one of seven choices based on the following question, “Do you regularly meet the following criteria set by the CDC? The seven sentences that the participants chose from were as follows: Yes, I meet the definition and have for MORE than 5 years (termination stage); Yes, I meet the definition and have for MORE than 6 months (maintenance stage); Yes, I meet the definition and have for between 0 and 6 months (action stage); No, but I intend to start meeting the definition regularly in the next 30 days and I currently am active (active preparation stage); No, but I intend to start meeting the definition regularly in the next 30 days though I am currently inactive besides daily walking (non-active preparation stage); No, but I intend to start meeting the definition regularly in the next 6 months (contemplation stage); No, and I do NOT intend to start meeting the definition regularly in the next 6 months (pre-contemplation stage). Achievement goals Achievement goals were assessed with a modification of Stevenson and Lochbaum’s (2008) exercise specific 2 2 achievement goal measure that was adapted from Elliot and McGregor’s (2001) measure. This instrument was designed to assess the four achievement goal orientations in relation to intentional physical activity. The instructions were “Please think about your thoughts and feelings when engaging in, or thinking about engaging in intentional physical activity.” Example questions were “it is important to me to perform as well as I possibly can” (masteryapproach); “it is important for me to do well as compared to others” (performance-approach); “I worry that I may not perform as well as I possibly can” (mastery-avoidance); “I just want to avoid performing worse than others” (performance-avoidance). Each goal was represented using 3 statements per subscale for a total of 12 items. The questionnaire required participants to rate their agreement with each statement on a scale from 1 (not at all true of me) to 7 (very true of me). A higher score on any of the achievement goal subscales indicated a stronger orientation toward that achievement goal. Past research has displayed strong psychometric properties (e.g., Stevenson & Lochbaum, 2008) with this measure. For the current study, Cronbach alphas were .74 (masteryapproach), .86 (mastery-avoidance), .86 (performance-approach), and .82 (performance-avoidance). Procedure After receiving institutional review board approval to conduct the study, permission was granted from instructors of a variety of academically based 1-h fitness courses to approach potential participants. Participants were approached for study involvement in the second week of classes so that the point at which the data were collected would not influence participants’ exercise stage of change assessment. Additionally, while it is highly unlikely that any participant had not been “physically active” in his or her life prior to the study, commencing the study in week two of the semester, would enable all students to have at least some physical activity experience in order to answer the 2 2 achievement goal exercise questionnaire worded for the physical activity context. The primary author or a research assistant informed potential participants of the study’s purpose, that extra credit was not being offered for participation, and that no punishment would occur for refusing to participate. Those who agreed to participate were handed the exercise packet. There were very few exceptions for participation. Data analysis To test our first three hypotheses, several 2 (Sex: male, female) by 6 (Stage: contemplation, non-active preparation, active preparation, action, maintenance, long term maintenance) multivariate analysis of variances (MANOVA) with the 2 2 achievement goals as the dependent variables were conducted. Follow-up tests were conducted with either univariate F-tests or the Ryane GabrieleWelsch Range post hoc tests when appropriate. To test HO4a/4b, identical MANOVA procedures were followed with a computed difference score that measured the contrast between Author's personal copy M. Lochbaum et al. / Psychology of Sport and Exercise 14 (2013) 161e168 165 Table 2 Effect sizes for mastery-approach, mastery contrast, performance-approach, and performance contrast for significant post hoc tests for stage of physical activity main effects.

Effect sizes denote that the stage in the row was greater in the achievement goal variable compared to the other stages (see column headings) in the corresponding row. the approach and avoidance goals (i.e., performance approachavoidance contrast and mastery approach-avoidance contrast). Following past research recommendations (e.g., Elliot et al., 2006; Stoeber & Crombie, 2010; Stoeber et al., 2009), all goals were first standardized prior to the contrast calculation (performance contrast ¼ zperformance-approach zperformance-avoidance; mastery contrast ¼ zmastery-approach zmastery-avoidance). Using standardized scores gives all goals equal weight in the contrast calculation. Last, effect sizes (Hedges, 1981) were calculated to determine the meaningfulness of statistically (p < .05) significant follow-up test differences. Cohen’s (1988) interpretation guidelines for effect sizes were followed such that an effect of .2 was consider small, .5 medium, and .8 large. These significant main effects were superseded by the significant (p < .01) sex by physical activity stage interaction, Wilks’ Lambda ¼ .94, F(20, 2617.76) ¼ 2.23. The follow-up univariate F-tests for the significant interaction revealed that the interaction occurred for the performance-approach, F(5, 7921) ¼ 6.99, p < .01, and performance-avoidance goals, F(5, 7921) ¼ 9.69, p < .01. Follow-up tests and visual inspection of the mean scores (see Fig. 1) suggested that the significant interaction was a result of female performance-approach scores declining from the action to the maintenance stage and then increasing to the long-term maintenance stage while the male performance-approach scores differed only from the non-active preparation stage to the rest of the stages. Results MANOVA results for HO1-3 The MANOVA results revealed significant (p < .001) main effects for sex, Wilks’ Lambda ¼ .85, F(20, 2617.76) ¼ 6.65, and physical activity stage, Wilks’ Lambda ¼ .96, F(4, 789) ¼ 8.19, on the achievement goals. Across stages, females were significantly (p .02) lower in the mastery-approach goal, F(1, 792) ¼ 5.37, ES ¼ .27, and higher in the mastery, F(1, 792) ¼ 7.17, ES ¼ .17, and performance-avoidance goals F(1, 792) ¼ 7.67, ES ¼ .18, compared to their male counterparts. Concerning the main effect for physical activity stage on achievement goals, univariate F-tests (p < .001) revealed that the differences potentially existed for both performance goals. The RyaneGabrieleWelsch Range post hoc tests (effect sizes found in Table 2) for the performance-approach goals revealed that the long-term maintenance group endorsed this goal significantly and meaningfully more than all of other groups except the action group. Moreover, the action group endorsed the performance-approach goal more than the non-active preparation group. For the mastery-approach goal the RyaneGabrieleWelsch Range post hoc tests (effect sizes found in Table 2) revealed that the long-term maintenance group significantly and meaningfully endorsed this goal more than the active preparation, non-active preparation and contemplation groups. The maintenance, action, and active preparation groups significantly endorsed the masteryapproach goal more than the non-active preparation and the contemplation group. Fig. 1.

Author's personal copy 166 M. Lochbaum et al. / Psychology of Sport and Exercise 14 (2013) 161e168 The performance-avoidance goal interaction (see Fig. 2) was a result of female scores being significantly higher in the long-term maintenance stage compared to those of the males as well as the male performance-avoidance scores gradual decline across all of the physical activity stages. preparation and contemplation groups; and (4) the two preparation groups differed with the active preparation group scoring higher in the performance contrast. MANOVA results for HO4a, 4b The main purpose governing the present investigation was to examine whether approach-avoidance achievement goals differed across a number of physical activity stages based on the transtheoretical model of behavior change (Prochaska & DiClemente, 1983). It was hypothesized that differences would exist among the non-exercising stages to the long-term maintenance stage in that participants would endorse both approach goals more (HO1) and both avoidance goals less (HO2). Two secondary purposes were also closely examined. The first secondary purpose was to test whether females endorsed both avoidance goals more than their male counterparts (HO3). We also explored the possibility of the performance (HO4a) and mastery (HO4b) goal contrasts being useful in understanding exercise stage, as the performance goal contrast has been valuable in better understanding sport performance (Elliot et al., 2006; Stoeber & Crombie, 2010; Stoeber et al., 2009). Given the importance of the mastery-approach goal to self-reported physical activity research (Lochbaum et al., 2009; Skjesol & Halvari, 2005; Wang et al., 2007), it was logical to examine this contrast as well. By and large, the results supported our four hypotheses. In addition, unique findings emerged such as the significant gender by stage interactions for both performance goals as well as meaningful differences between the two preparation stages, active and non-active, as well as differences amongst the other physical activity stages and the two preparation stages. Historically, the dichotomous goal approach has been conceptually identical to the performance- and mastery-approach goals as both the task and ego goals have always been positively valenced (Elliot, 1997, 1999). In the sport, exercise, and physical activity literature however, a premium has always been placed on the benefits of the task or mastery goal while casting doubt on the motivationally adaptive benefits of the ego or performance referenced goal (Roberts et al., 2007). The present research strongly supports the importance of the bifurcation of the performance goal into a positively valenced approach dimension and a negatively valenced avoidance dimension. Though some researchers have called the split unnecessary (Midgley, Kaplan, & Middleton, 2001), Elliot and Moller (2003) and Linnenbrink (2005) have contended that this division is necessary as the performance-approach goal has theoretically positive and motivationally beneficial effects, while the performance-avoidance goal has negative and motivationally detrimental effects. We assert that given the social nature of physical activity pursuits (e.g., health clubs, recreation centers, team sports) that it is very likely that both types of performance goals naturally exist in these public settings. Consistent with Elliot and Moller (2003) and Linnenbrink’s (2005) reasoning, we found that the performance-approach goal was beneficial to long term exercise as reported by participants in the present investigation. The motives for exercise and physical activity literature provide an explanation for the importance of the performance-approach goal results and possibly the performance-avoidance results. Quindry, Yount, O’Bryant, and Rudisill (2011) examined exercise motives across adolescence to old age (age range 13e84) with the Exercise Motivation Inventory-2 (EMI-2) questionnaire (Markland & Ingledew, 1997). Their results clearly pointed to adolescents (defined as <19 years of age in the study) and young adults (defined as between 20 and 34 years of age) endorsing interpersonal motives of social recognition, affiliation, and competition for physical activity pursuits compared to middle, young, and old adults. These interpersonal motives are clearly in the domain of The MANOVA results revealed significant (p < .001) main effects for sex, Wilks’ Lambda ¼ .96, F(2, 791) ¼ 15.95, and physical activity stage, Wilks’ Lambda ¼ .87, F(10, 1582) ¼ 10.81. Females were significantly (p < .001) lower in the performance contrast, F(1, 792) ¼ 27.74, ES ¼ .33, and the mastery contrast, F(1, 792) ¼ 14.87, ES ¼ .45, compared to their male counterparts. Concerning the stage of physical activity main effect, univariate F-tests (p < .001) revealed that the differences potentially existed for both contrasts [mastery contrast, F(5, 792) ¼ 15.51; performance contrast, F(5, 792) ¼ 14.02]. The RyaneGabrieleWelsch Range post hoc tests for the mastery contrast revealed the following (see Table 2 for effect size values): (1) the long-term maintenance group endorsed this goal significantly more than all of the other groups, except the maintenance group; (2) the maintenance group endorsed the mastery contrast more than the preparation and the contemplation groups; (3) the action group endorsed the mastery contrast more than the non-active preparation and contemplation groups; (4) and the two preparation groups differed with the active-preparation group scoring higher in the mastery contrast more so than the nonactive preparation group. For the performance contrast the RyaneGabrieleWelsch Range post hoc tests revealed the following (again the effect sizes for these significant results are found in Table 2): (1) the long-term maintenance group endorsed this goal significantly more than all of other groups except the maintenance group; (2) the maintenance group endorsed the performance contrast goal more than the nonactive preparation and contemplation groups; (3) the action group endorsed the performance contrast more than the non-active Fig. 2.

Note that * indicates (p < .01) difference between males and females at the longterm maintenance stage with an ES difference of 1.16 between males and females; the ES difference between B and A is .65 and p < .01. Similar letters indicate significant differences were not present (i.e., A to AB or AB to B). Discussion Author's personal copy M. Lochbaum et al. / Psychology of Sport and Exercise 14 (2013) 161e168 performance goals reported among participants in the latter exercise stages in this investigation. These findings are consistent with those of Kilpatrick, Herbert, and Bartholomew (2005) who using the EMI-2 reported that male undergraduate students endorsed competition and social recognition (i.e., performance goals) more so than their female counterparts. Of further interest, the male pattern of performance-approach goal endorsement, as seen in Fig. 1, demonstrated significant differences from the non-active to the active preparation stage. Though purely speculative, the active preparation stage could represent competitive males that play intramural sports or other such competitive contests typically found on university campuses. For the sampled females, the performance-approach goal was characteristic of the long-term maintenance stage more so than any of the other stages. The appetitive nature of the approach goals appear conducive to selfinitiated physical activity. This appetitive nature process allows for personal comparisons to others whether publically at a recreation center or to the instructors and participants found in targeted home based activity programs via DVD’s and web sites. We also found an interaction between sex and stage on the performance-avoidance goal as well as a small and significant difference in the avoidance goal between females and males. The interaction finding, as was the performance-approach interaction, was unique to the physical activity literature. Historically (see Stein & Bailey, 1973), sex differences in avoidance motivation have been hypothesized to be the result of societal sex role definitions that impact parental socialization and rearing patterns. In particular, females have traditionally been encouraged to pursue noncompetitive, mastery based experiences rather than male-oriented competitive endeavors. Differences in exercise motives such as appearance could also explain the sex difference in the performanceavoidance goal. This possible explanation is consistent with findings reported by Kilpatrick et al. (2005). The authors reported that female college students reported ill-health avoidance significantly and very meaningfully (ES ¼ .91) more than their male college counterparts. Lochbaum, Stevenson, Hilario, Surles, and Havenar (2008) have the only published data with the approach goals (task and ego) and exercise stages. Although these data were with female participants only, they support the current results in that the ego goal was not a meaningful discriminating variable in the measured stages. The stages measured by Lochbaum et al. (2008) were pre-contemplation, contemplation, preparation, action and maintenance. The sex by physical activity stage interactions of the present investigation highlights the importance of measuring the long-term maintenance stage as these females endorsed the performance-avoidance goal significantly and very meaningfully more so when compared to the other physical activity stages. Up to this point, the discussion has focused on the performance goal findings. With regard to the mastery goals, the overall pattern of findings was supportive of hypotheses for the mastery-approach goal, the mastery goal contrast, and the sex difference found for the mastery-avoidance goal. Consistent with the mastery-approach relationship with self-reported leisure time physical activity (Lochbaum et al., 2009; Skjesol & Halvari, 2005; Wang et al., 2007), this goal was characteristics of the more advanced exercise stages of action, maintenance, and long-term maintenance. College students in Kilpatrick et al. (2005) investigation rated positive health, enjoyment, and challenge as important motives. These motives clearly define aspects of a mastery-approach mindset. Surprisingly, in the present study, the mastery-avoidance goal was nearly consistent across all exercise stages for both sexes; overall the females significantly endorsed this goal as hypothesized, although the effect was small. In regards to hypothesis four, we predicted that the contrast score would increase (performance-approach > performance-avoidance) 167 across the physical activity stages (HO4a), and that a mastery contrast score would be more characteristic of the advanced exercise stages (HO4b). As stated previously, the use of goal contrasts has been limited to the performance contrast in the sport psychology literature (Elliot et al., 2006; Stoeber & Crombie, 2010; Stoeber et al., 2009). The present results strongly supported our hypotheses suggesting that both the performance and mastery goal contrast could be valuable in understanding adult exercise patterns more so than examining each goal independently. Specifically, for both the mastery and performance goal contrasts, differences were found with the participants in the long-term maintenance and maintenance groups endorsing both contrasts the most. The contrast mean differences demonstrated an important change across the stages from negative (avoidance goal > approach goal) in the nonexercising stages to positive (approach goal > avoidance goal) in the exercising stages. The gender differences were meaningful in that the contrast score was greater in the males. Though the gender by stage interactions were not significant, an examination of the mean performance contrast scores suggest that females in the action and maintenance stages were lower in the performance contrast score compared to males in the same stages and contributed to the overall differences more so than the other stages. Limitations and future directions Taken together, the findings support the importance of approach-avoidance achievement goals in the leisure time physical activity context. The unique findings in the present study and the large sample notwithstanding, there are limitations that warrant mention. A cross-sectional design governed the present investigation, and therefore does not allow for causal claims that involvement in physical activity changes achievement goals or that achievement goals are the reason for differing levels and commitment to physical activity. In addition, the cross-sectional design does not allow for an understanding of within-person behavioral change processes. Thus, future investigations that determine the stability of the achievement goal profiles and gender interactions with regards to leisure time physical activity would be beneficial in substantiating the importance of the reported findings. Though the sample of college students was appropriate to answer the questions posed, samples across the lifespan would add to a better understanding of achievement goal profiles. For instance, motives for exercise have been found to change over the lifespan from interpersonal motives (e.g., social affiliation) to intrapersonal ones (e.g., personal improvement; Quindry et al., 2011). Thus, it could be that the mastery goals and goal contrasts are more important for consistent planned physical activity in middle to old age, a suggestion warranting further empirical examination. Last, selfreported stage of physical activity may suffer from bias. It is possible that participants might have overestimated their current exercise stage. These potential limitations aside, findings suggest the benefit of promoting both performance and mastery approach goals in encouraging exercise involvement. Findings also highlight the need to consider gender when promoting particular goal orientations for increasing physical involvement. Last, strong support for the use of goal contrasts as well as re-examining the traditional preparation stage into two distinct sub stages are warranted in future research. References Bauman, A.
