RESUMEN
The school-based mental health promotion and suicide prevention universal program Youth Aware of Mental Health (YAM) significantly reduces incident suicide attempts and severe suicidal ideation. This paper aims at elucidating psychological mechanisms underlying YAM's efficacy. Our hypothesis is that YAM operates through interactions with coping strategies (CS) on the reduction of suicidal ideation (SI). In the Saving and Empowering Young Lives in Europe (SEYLE) study, five coping strategies were assessed at baseline (T0) and 12-month follow-up (T12): "learning", "help-seeking", "arts", "sports" and "fight". We analyzed interactions between the YAM intervention, coping strategies and SI in the YAM group (N = 1693) and the minimal intervention group (N = 1909), after excluding prevalent cases with SI and previous suicide attempts from our total sample (N = 5654). General Linear Mixed Model regressions were performed. The present study confirms that coping strategies play an influential role on suicidal ideation. Our results showed that YAM acts whatever the prevailing coping strategies used. It is particularly efficient for pupils insufficiently using adaptive coping strategies such as LEARN and HELP-SEEKING or using maladaptive coping strategies, such as ARTS and FIGHT. The socialization induced by the YAM intervention seems to be a strong component of its efficiency.
