Abstract

This study aimed to evaluate direct and indirect effects of behavioral inhibition system (BIS) and behavioral activation system (BAS) on depression and current suicidal ideation through rumination and self-reflection in a sample of suicide attempters. Three hundred suicide attempters completed the Rumination/Reflection Questionnaire (RRQ), the Carver and White BIS/BAS scales, the Beck Scale for Suicide Ideation (BSSI), and the Beck Depression Inventory-II (BDI-II).

RESULTS revealed that BAS and BIS had direct effect on suicidal ideation, but not depression. Low BAS had indirect effect on depression through decreased self-reflection. High BIS had indirect effect on depression via increased rumination. Low BAS and high BIS had indirect effects on suicidal ideation through decreased self-reflection. The findings suggest that low BAS and high BIS may be associated with depression and suicidal ideation in suicide attempters who have decreased self-reflection and increased rumination. Also, increasing self-reflection and reducing rumination as respectively adaptive and maladaptive self-focused attention strategies may prohibit depression and suicidal ideation.
