There is growing interest in a prevention based approach to mental disorders [Our results suggest that a two-stage screening and referral system can be effective at reducing the point prevalence and incidence of PEs at 12-months. Our results expand the findings from the university setting [The reason for the efficacy of the universal screener and selective intervention in this study then may be better explained by the act of being contacted by a health professional, rather than the meeting with the professional. Previous RCTs have observed an improved effect of intervention driven by more frequent follow-up contact [An alternative explanation may be a down-stream effect of interventions. The primary goal of the SEYLE study was to examine the effectiveness of interventions for suicidal behaviour, rather than PEs. PEs are associated with suicidal thoughts and behaviour [Neither the teacher training (QPR) or universal psychoeducational (YAM) intervention showed significant evidence of preventing PEs. The universal psychoeducational intervention did reduce depression scores in young people with PEs at 12-months. In the full SEYLE sample, this intervention also significantly reduced the incidence of suicidal ideation & attempts at 12-month follow-up [Our secondary aim found those who reported PEs at baseline showed a greater improvement in anxiety and depression scores, relative to those without PEs, following the ProfScreen intervention. Previous research has observed differences in outcomes for PEs with and without co-occurring mental disorders [
