Protective Effects of Reasons for Living Against Suicidal Ideation in Daily Life
How do individuals resist suicidal urges in a suicidal crisis? Deterrents for suicide can be conceptualized as reasons for living (RFL), but our understanding of their protective effects is predominantly informed by cross-sectional research. We examined the protective effects of RFL on suicidal ideation (SI) in daily life in a high-risk sample. We also tested whether personality traits moderated the strength of the dynamic RFL-SI link. Adults with a borderline personality disorder diagnosis (n=153, 105 suicide attempters) completed a 21-day ambulatory assessment protocol. Daily endorsements of RFL were negatively linked to SI at the within-person but not the between-person level. Whereas suicide attempters endorsed RFL less frequently than non-attempters, their protective effect was undiminished in this group. While people high on openness and extraversion endorsed RFL more often, this increase was not protective against SI, indicating that RFL reflect heterogeneous underlying psychological processes, only some of which are protective against SI.
