2005 Massachusetts Youth Risk Behavior Survey 6 CHAPTER 6 SUICIDALITY AND SELF-INFLICTED INJURY INTRODUCTION Nationally, youth suicide rates tripled in the second half of the 20 th century (6a). In 2003, suicide was the third leading cause of death among young people aged 15 to 24 in Massachusetts and in the United States as a whole (6b). One risk factor for suicide is untreated depression, yet only a small percentage of Americans who suffer from depression are accurately diagnosed and treated (6c). Other risk factors include bullying, other physical or sexual abuse, interpersonal losses, and school or work problems (6d). National Health Objectives for the Year 2010 include reducing the incidence of suicide attempts and completed suicides among adolescents. The 2005 MYRBS asked students several questions about suicidal thoughts and behaviors during the previous year, including questions concerning (1) feeling sad or hopeless, (2) serious considerations of suicide, (3) plans to commit suicide, (4) actual suicide attempts, and (5) medical treatment required as the result of a suicide attempt. In addition, the MYRBS asked about intentional self-injury including cutting, burning, or bruising. KEY FINDINGS FROM THE 2005 MYRBS Significantly fewer students in 2005 than in previous years seriously considered suicide (13%), made a suicide plan (12%), or actually attempted suicide in the past year (6%). Two percent (2%) of all students received medical attention for a suicide attempt. Slightly less than one-fifth of all students (19%) reported hurting themselves on purpose. Female students were more likely than male students to report suicidal thinking, feeling sad or hopeless for two weeks or more, or to have injured themselves on purpose. Small gender differences in actual suicide attempts were not statistically significant. Students receiving special education services, homeless students, sexual minority youth, students who engaged in binge drinking or illegal drug use, and students who have experienced violence were more likely than their peers to report a suicide attempt. RESULTS In the past decade, suicidality has decreased significantly among Massachusetts high school students. Feeling sad and hopeless for an extended period of time has declined, as have considering suicide, making a suicide plan, or making an actual suicide attempt. (Figure 6a) Female adolescents were more likely than males to have hurt themselves on purpose, to have felt sad or depressed for two weeks or more, to have considered suicide, or to have made a suicide plan. Gender differences in actual suicide attempts in the past year were not statistically significant.

Suicidality & Self-Inflicted Injury 49 2005 Massachusetts Youth Risk Behavior Survey Female adolescents were more likely than males to have hurt themselves on purpose, to have felt sad or depressed for two weeks or more, to have considered suicide, or to have made a suicide plan. Gender differences in actual suicide attempts in the past year were not statistically significant. (Figure 6b) Nearly one in five students (19%) indicated that they had hurt themselves on purpose at least once in the past year, for example by cutting, burning, or bruising themselves. This represents a slight, non-significant, increase over the 18% reported in 2003, the first year the question was included on the survey. ADDITIONAL GROUP DIFFERENCES IN SUICIDALITY Community differences in suicidality varied by question asked. Rural youth were more likely than their urban or suburban counterparts to indicate that they had cut, burned or hurt themselves on purpose in the past year (23% vs. 16% and 19%). On the other hand, rural adolescents were less likely than urban and suburban peers to report that they had made a past-year suicide attempt that resulted in an injury (1.3% vs. 3.3% and 2.2%). Other community differences were not significant. Special education students were more likely than general education students to report considering suicide (17% vs. 12%), making a suicide plan (15% vs. 11%), and making a suicide attempt resulting in injury (5% vs. 2%). Sexual minority adolescents – those who self-identified as gay, lesbian, or bisexual or who reported any samesex sexual contact – had suicidality rates nearly double those of their peers. For example, they were more likely to have hurt themselves on purpose (44% vs. 17%), to have seriously considered suicide (34% vs. 11%), and to have made a suicide attempt in the past year (21% vs. 5%). Immigrant and US-born adolescents were similar in terms of suicidal thinking and behavior. Every measure of suicidality was over twice as high among homeless youth as among adolescents living at home with their families. For example, homeless students were significantly more likely than their peers to have hurt themselves on purpose (38% vs. 17%), to have seriously considered suicide (28% vs. 12%), and to have made a suicide attempt in the past year (19% vs. 6%). RISK AND PROTECTIVE FACTORS FOR SUICIDALITY As has been found in numerous other studies, substance abuse was significantly associated with suidicality. For example, past-year suicide attempts were significantly more frequent among youth who reported binge drinking than among those who did not (11% vs. 5%) and among those who had ever used cocaine than among those who had not (24% vs. 5%). Suicidal thinking and behavior were more common among youth who had been victimized. For example, pastyear suicide attempts were significantly more common among students who had been bullied at school than among their peers (12% vs. 5%) and among adolescents who had experienced dating violence than among their peers (23% vs. 5%). Suicide attempts were reported significantly more frequently by overweight adolescents than by their peers (9% vs. 6%). Perceived social support appeared to exert a protective effect against suicidality. Suicide attempts were less common among students who believed there was a teacher or other school staff member they could talk to if they Suicidality & Self-Inflicted Injury 50 2005 Massachusetts Youth Risk Behavior Survey had a problem (5% vs. 11%) and among youth who reported that they could talk with family adults about things that were important to them (5% vs. 13%). Students who were earning passing grades – A’s, B’s, and C’s – were significantly less likely to have made a suicide attempt in the past year than those who were not (5% vs. 12%) CONCLUSIONS AND RECOMMENDATIONS Massachusetts can be encouraged by the significant declines in suicidal thinking and behavior among youth over the past decade. Even so, over one-eighth of Massachusetts high school students report having felt so much distress and despair over the past year that they seriously consider killing themselves; many actually make suicide attempts. All schools and communities need to address the seriousness of adolescent suicide. The National Strategy for Suicide Prevention includes an objective to increase the proportion of school districts and private school associations with evidence-based programs designed to address serious childhood distress and prevent suicide (6e). Researchers have begun to identify successful school-based approaches to youth suicide prevention (6f, 6g). Schools can address the problem of youth suicide directly using effective prevention programs that help students learn to recognize and manage the feelings of stress and depression that may lead to suicidal thinking and behavior. However, research has shown that suicidal adolescents are not likely to seek help on their own (6e). Therefore, it is important that school staff be trained to recognize early signs of depression and serious emotional disturbances among young people (particularly among high-risk subgroups such as sexual minority youth, and students who have been victims of violence), and be able to direct at-risk students to appropriate mental health services. One early sign of depression and suicidality may be self-inflicted injury. Students who reported hurting themselves on purpose (for example, by cutting, burning, or bruising themselves) were far more likely than their peers to have felt sad or hopeless, or to have considered, planned, or attempted suicide. Many influences may contribute to an adolescent’s intention to commit suicide, but some promising protective factors have also been identified. Recent research from the National Longitudinal Study on Adolescent Health found suicidality to be significantly lower among high school students who felt emotionally connected to their parents and/or family (6h). The 2005 MYRBS results support that view. Massachusetts students who felt there was a parent or other adult in their family they could talk to about things that were important were less likely than their peers to have attempted suicide. Conversely, adolescents who were threatened, bullied, or intimidated at school or who felt so unsafe that they sometimes skipped school altogether had far higher rates than their peers of suicidal thinking and behavior. Schools should work to foster an environment in which all students feel safe, accepted, and supported, and where all have the opportunity for social recognition and for responsible involvement in school activities.
