The longitudinal relationship of psychological and social-environmental factors with adolescent suicidal ideation over a 1-year-period was examined in a sample of 374 high school students. Students were assessed twice over a 1-year period with measures of depression, hopelessness, major negative life events, daily hassles, social support, and suicidal ideation. At the initial assessment, daily hassles and negative life events for males and social support and depression for females were significant factors related to suicidal ideation levels 1 year later. Changes in depression and hopelessness were significantly related to changes in suicidal ideation over the 1 year interval for males and females. Differences found between males and females in the relationship of psychological and social-environmental variables with suicidal ideation supports the need to examine gender specific relationships when conducting research on suicidal behavior in adolescents.

"Research has indicated that history of SI is a robust predictor of eventual suicide attempts (Brown et al., 2000; Mazza and Reynolds, 1998), and that PB and TB (Joiner et al., 2009) are proximal risk factors of SI. With these established relationships, it is important to identify predispositional risk factors of these variables. "
[Show abstract][Hide abstract] ABSTRACT: Research has demonstrated an inconsistent relationship between suicide ideation and personality traits. This is the first study to empirically examine the relationship of the Five Factor Model of personality with current, past and no suicide ideation, and with the two interpersonal risk factors of suicide: thwarted belongingness and perceived burdensomeness (Joiner, 2005). Results indicate that high neuroticism was associated with both current ideation and a history of suicide ideation and extraversion was associated with current ideation. Neuroticism was positively related to thwarted belongingness and perceived burdensomeness, while extraversion was negatively related to these interpersonal predictors of suicide. Agreeableness was negatively related to thwarted belongingness but not perceived burdensomeness, indicating differentiated patterns of relationships between this personality domain and the two suicide constructs. Furthermore, these personality domains predicted 23.82% of variance for thwarted belongingness and 15.07% of the variance for perceived burdensomeness, above and beyond demographic variables associated with suicide ideation. This study, which was conducted with a college sample, demonstrates the potential benefit of identifying predispositional risk factors for suicide ideation and interpersonal predictors of suicide. This may have implications for the development of upstream preventative measures against suicide.

"Regarding reliability, the results indicate that the SIQ has a high level of internal consistency and satisfactory test-retest reliability over a 2-week period, in line with the findings of Reynolds (1991), Pinto et al. (1997) and Mazza and Reynolds (1998). Although the results are powerful and little difference has been found between paper and on-line measures for psychological research (Riva et al., 2003), it should be emphasized that the sample of study 3 (testretest ) was small, thereby limiting statistical power and increasing the likelihood of a Type II error.

[Show abstract][Hide abstract] ABSTRACT: Teenage suicide is a major public health issue in Western societies, especially in France. An instrument to measure suicidal thoughts in French adolescents and thus identify the teenagers at risk is urgently required. The aim of this study was to validate a French version of the Suicidal Ideation Questionnaire (SIQ) for use with teenagers. Respondents (n=956, age range 14-18.0) completed the SIQ and other convergent measures (self-esteem, psychic morbidity, anxiety, and personality) for three validation steps (general and clinical samples). A confirmatory factor analysis was performed on the SIQ. The study supported a 30-item one-factor model, similar to the original questionnaire, with moderate model fit indices (χ(2)/ddl=3.21; RMSEA=0.05; CFI=0.87; GFI=0.92). Significant correlations (-0.22 to 0.74) were found with convergent measures among general (n=871) and psychiatric samples (n=38). A high internal consistency was found with a reliability coefficient of 0.91. The results confirm the psychometric qualities of the questionnaire for French adolescents.

"For example, hopelessness, considered to be a strong indicator of suicide risk (Mazza and Reynolds 1998), may help to explain the relationship between loneliness and suicidality in youth. Loneliness is associated with feelings of hopelessness in adolescents (Page 1991), and a domain-specific form of social hopelessness has been linked to suicidal ideation in young adults (Heisel et al. 2011). "
[Show abstract][Hide abstract] ABSTRACT: Recent research has shown that social anxiety may be related to increased risk for suicidal ideation in teens, although this research largely has been cross-sectional and has not examined potential mediators of this relationship. A clinical sample of 144 early adolescents (72 % female; 12-15 years old) was assessed during psychiatric inpatient hospitalization and followed up at 9 and 18 months post-baseline. Symptoms of social anxiety, depression, suicidal ideation, loneliness, and perceived social support were assessed via structured interviews and self-report instruments. Structural equation modeling revealed a significant direct relationship between social anxiety symptoms at baseline and suicidal ideation at 18 months post-baseline, even after controlling for baseline depressive symptoms and ideation. A second multiple mediation model revealed that baseline social anxiety had a significant indirect effect on suicidal ideation at 18 months post-baseline through loneliness at 9 months post-baseline. Social anxiety did not have a significant indirect effect on suicidal ideation through perceived social support from either parents or close friends. Findings suggest that loneliness may be particularly implicated in the relationship between social anxiety and suicidality in teens. Clinicians should assess and address feelings of loneliness when treating socially anxious adolescents.
