The Common Elements of treatment engagement for clinically high‐risk youth and youth with first‐episode psychosis

Aim Without treatment, clinically high-risk (CHR) youth or youth with first-episode psychosis (FEP) have increased risk for significant complications from their illness; yet, treatment engagement among these youth is critically low. The purpose of this study was to examine engagement efforts with CHR/FEP youth to stimulate new ideas that might facilitate participation in services for this population. Methods A literature review using distillation methods identified engagement practices reported in two bodies of literature. The first body of literature (i.e. ‘CHR/FEP engagement’) included 13 studies employing qualitative designs to explore consumer perspectives about treatment engagement practices in samples of CHR/FEP youth and their families. The second body of research (i.e. ‘CHR/FEP RCTs’) included 18 randomized controlled trials (RCTs) testing treatments for CHR/FEP youth and their families. Engagement practice frequencies were compared with the frequency of these practices within effective engagement interventions, as tested in 40 RCTs within the broader child and adolescent mental health literature (i.e. ‘CAMH engagement’). Results Treatment attrition and attendance were the most frequent engagement outcomes measured in the CHR/FEP RCTs. There were notable efforts described in the CHR/FEP RCTs towards engaging youth and families, yet CHR/FEP RCTs reportedly included only a small proportion of engagement practices described in either the CHR/FEP or CAMH engagement literatures. Conclusion Results suggest there might be practices available to complement current efforts at engaging CHR/FEP youth in treatment, and that increased attention to the measurement of engagement outcomes could provide important information regarding engagement in a population with low treatment engagement rates.
