Problem solving as an active ingredient in indicated prevention and treatment of youth depression and anxiety: A critical review and synthesis of trial outcomes, qualitative evidence and lived experience insights
Background: Problem solving is a key developmental capacity and a common focus of psychological interventions for young people. Despite widespread use of problem solving in practice, existing evidence syntheses of this therapeutic approach are relatively limited in their scope and conclusions. Method: We examined the role of problem solving as an active ingredient for the indicated prevention and treatment of depression and anxiety in 14-24-year-olds. Three information sources were integrated: (i) a systematic review of randomised controlled trials of problem solving; (ii) a meta-synthesis of qualitative evidence on the therapeutic experience of problem solving; and (iii) consultation with a youth advisory group. Results: Problem solving appeared to be effective as a sole intervention for depression but not anxiety. Multi-component interventions with a problem-solving element achieved moderate effect sizes for both conditions. There was no clear evidence that effectiveness varied by population characteristics, intervention formats or contextual factors. Evidence about why problem solving works was generally consistent with Lazarus & Folkman’s “stress-coping” theory.Discussion: Problem solving is a widely applicable therapeutic approach that can help young people with emotional problems to resolve specific stressors and lead to a more hopeful mindset about managing future challenges. Implications for practice are discussed.
