Exposure to Violence in Young Inner-City Adolescents: Relationships With Suicidal Ideation, Depression, and PTSD Symptomatology

This study examined the relationship of exposure to violence to suicidal ideation, depression, and post-traumatic stress disorder (PTSD) symptomatology in 94 young adolescents from an inner-city school. Participants completed self-report measures of the Reynolds Adolescent Depression Scale, the Suicidal Ideation Questionnaire—Junior, Adolescent Psychopathology Scale—Posttraumatic Stress Disorder Subscale, and the Exposure to Violence Questionnaire. Using a hierarchical multiple regression design, exposure to violence demonstrated a unique relationship with PTSD symptomatology. Specifically, the relationship between violence exposure and PTSD symptomatology remained significant after controlling for depression and suicidal ideation severity. Controlling for PTSD symptomatology resulted in nonsignificant relationships between violence exposure and depression and suicidal ideation in adolescents. Additional analyses suggest that PTSD functions as a mediating variable between exposure to violence and depression and suicidal ideation. The implication of these results and suggestions for future research are discussed.     

The problem-solving diathesis in depression,hopelessness, and suicide ideation: A longitudinal analysis

The problem-solving deficit (PSD) diathesis-stress model of suicide behavior proposed by Clum, Patsiokas, and Luscomb (1979) and expanded by Schotte and Clum (1982, 1987) was examined in a short-term longitudinal test. The present study assessed the relationship between problem-solving deficits at Time 1—prior to the stressor (a D or F on a midterm examination)—and adjustment at Time 2—after the Stressor. Evidence was found for an additive predictive relationship for stress and problem-solving deficits to Time 2 measures of depressive symptoms, hopelessness, and suicide ideation. Evidence was also found that PSD × Stress interactions uniquely predicted the three criteria. The results of this study were taken as evidence of problem-solving deficits functioning as a diathesis for depression, hopelessness, and suicide ideation.     

Epidemiology,Risk Factors,and Prevention of Suicidal Thoughts and Behaviour in Prisons: A Literature Review

Suicide is a global public health concern that affects all echelons of society, albeit not equally so. Compared with adults in the general population, incarcerated offenders are at increased risk to consider, attempt, and die by suicide, which represents a substantial burden of morbidity and mortality in prisons worldwide. This review synthesises recent literature pertaining to the epidemiology, risk factors, and prevention of suicidal thoughts and behaviour among prisoners, and outlines a framework which emphasises the interplay between individuals (importation) and their surroundings (deprivation). The available evidence suggests that prison-specific stressors may exacerbate risk of suicide in an already vulnerable population characterised by complex health and social care needs. Emerging data point to differential mechanisms through which prisoners come to think about suicide and subsequently progress to suicidal behaviour. As risk of suicide is determined by a complex web of synergistically interacting factors, its management and prevention demands a cross-sectoral policy and service response that includes targeted interventions aimed at high-risk prisoners in combination with population strategies that promote the health and wellbeing of all people in prison.     

The Relative Contribution of Diagnostic and Psychosocial Variables to Severity of Suicidal Ideation

The present study examined the relative contribution of diagnostic and psychosocial factors to the prediction of severity of suicidal ideation in a sample of 78 college students. Using hierarchical regression analyses to control for each set of factors, psychosocial variables were found to consistently predict level of suicidal ideation. In contrast, diagnostic variables including diagnosis of substance abuse and composite scores for depression and anxiety were unrelated to level of suicidality. An examination of individual diagnoses revealed no predictable relationships with severity of suicidality in this population. The results were discussed from several methodological viewpoints.     

父母忽视对青少年自杀意念的影响:自尊和希望的中介作用

为考察父母忽视对青少年自杀意念的影响及其作用机制,采用父母忽视量表、自尊量表、希望量表和自杀意念量表,对全国七个省份八所中学共845名初二学生进行调查。结果表明：（1）父母忽视、自尊、希望和自杀意念两两之间存在显著的相关,且父母忽视对自杀意念具有显著的正向预测作用;（2）自尊和希望在父母忽视与自杀意念的关系中起部分中介作用。具体而言,父母忽视通过三条路径影响自杀意念：一是自尊的单独中介作用;二是希望的单独中介作用;三是自尊-希望的链式中介作用。本研究揭示了父母忽视与青少年自杀意念的关系及其作用机制,对预防以及减少青少年自杀行为具有一定的现实意义。     

Low self-esteem and hopelessness in childhood and suicidal ideation in early adulthood

This study examined the longitudinal relationship between family characteristics in early childhood, self-esteem, hopelessness and thoughts of self-harm in the midchildhood years, and suicidal ideation at ages 18 and 21. Path analysis was used to establish separate models for boys and girls. The results suggested different pathways to later suicidal ideation for boys and girls. For boys, suicidal ideation seemed to have stronger roots in childhood, with significant paths from low self-esteem and hopelessness to early thoughts of self-harm and thence to later ideation. For girls, self-esteem had a small but significant direct effect on later suicidal ideation. The findings provide support for the idea that individual characteristics such as feelings of hopelessness and low self-esteem act as generative mechanisms, linking early childhood family characteristics to suicidal ideation in early adulthood.     

Loose but normal: a semantic association study

An abnormal facilitation of the spreading activation within semantic networks is thought to under-lie schizophrenics' remote associations and referential ideas. In normal subjects, elevated magical ideation (MI) has also been associated with a style of thinking similar to that of schizotypal subjects. We thus wondered whether normal subjects with a higher MI score would judge "loose associations" as being more closely related than do subjects with a lower MI score. In two experiments, we investigated whether judgments of the semantic distance between stimulus words varied as a function of MI. In the first experiment, random word pairs of two word classes, animals and fruits, were presented. Subjects had to judge the semantic distance between word pairs. In the second experiment, sets of three words were presented, consisting of a pair of indirectly related, or unrelated nouns plus a third noun. Subjects had to judge the semantic distance of the third noun to the word pair The results of both experiments showed that higher MI subjects considered unrelated words as more closely associated than did lower MI subjects. We conjecture that for normal subjects high on MI "loose associations" may not be loose after all. We also note that the tendency to link uncommon, nonobvious, percepts may not only be the basis of paranormal and paranoid ideas of reference, but also a prerequisite of creative thinking.     

Multidimensional Suicide Inventory-28 (MSI-28) Within a Sample of Military Basic Trainees: An Examination of Psychometric Properties

Suicide and suicidal ideation are serious public health concerns. Accurate detection and assessment are critical first steps in addressing this challenging issue. The present study examined self-reported suicidal ideation in a sample of United States Air Force enlisted active duty basic trainees (N = 470) using the Multidimensional Suicide Inventory (MSI-28). Exploratory factor analyses revealed a 4-factor structure for the MSI-28 in this sample. Together, these 4 factors explained approximately 72% of the variance in the MSI-28. The MSI-28 evidenced moderate to strong associations with measures of resilience (Dispositional Resilience Scale-15; DRS-15) and psychological distress (Outcome Questionnaire; OQ-30.2). These findings demonstrate that the MSI-28 is a promising tool for clinical measurement of self-reported suicidality. Future directions for further validation of the MSI-28 are discussed.
