Perceived Peer and Family Relationships,Hopelessness and Locus of Control as Factors in Adolescent Suicide Attempts

ABSTRACT: Thirty hospitalized suicidal adolescents were compared with thirty-four hospitalized nonsuicidal teenagers and thirty-five nonhospitalized coping youngsters (controls) on the extent of their problems, their perceptions of peer and family relationships, degree of hopelessness, and locus of control. Suicidals were found to experience the greatest total number of problems, nonsuicidals the next most, and controls the fewest. Significantly more peer problems differentiated the suicidals from the other two groups, while serious family problems discriminated the three groups from each other. The controls viewed their families as the most well-adjusted, followed by the nonsuicidals, while the suicidals felt their families were the most maladjusted. Suicide attempters experienced a significantly greater degree of hopelessness than all the nonattempters, and significantly more external locus of control than the controls. Some sex differences emerged in the study.     

Selective attention modulates implicit learning

The effect of selective attention on implicit learning was tested in four experiments using the "contextual cueing" paradigm (Chun & Jiang, 1998, 1999). Observers performed visual search through items presented in an attended colour (e.g., red) and an ignored colour (e.g., green). When the spatial configuration of items in the attended colour was invariant and was consistently paired with a target location, visual search was facilitated, showing contextual cueing (Experiments 1, 3, and 4). In contrast, repeating and pairing the configuration of the ignored items with the target location resulted in no contextual cueing (Experiments 2 and 4). We conclude that implicit learning is robust only when relevant, predictive information is selectively attended.     

Helping Callers to the National Suicide Prevention Lifeline Who Are at Imminent Risk of Suicide: Evaluation of Caller Risk Profiles and Interventions Implemented

Crisis lines are settings where identifying individuals at imminent risk of suicidal behavior and intervening to keep them safe are critical activities. We examined clinical characteristics of crisis callers assessed by telephone crisis helpers as being at imminent risk of suicide, and the interventions implemented with these callers. Data were derived from 491 call reports completed by 132 helpers at eight crisis centers in the National Suicide Prevention Lifeline network. Helpers actively engaged the callers in collaborating to keep themselves safe on 76.4% of calls and sent emergency services without the callers' collaboration on 24.6% of calls. Four different profiles of imminent risk calls emerged. Caller profiles and some helper characteristics were associated with intervention type. Our findings provide a first step toward an empirical formulation of imminent risk warning signs and recommended interventions.
