The impact of interventions for depression on self-perceptions in young people: A systematic review & meta-analysis

Negative self-perceptions are implicated in the development and maintenance of depression in young people, but little is known about their receptiveness to change in response to treatment. This paper reports on a preregistered meta-analysis examining the extent to which treatments for depression in young people aged 11-24 result in changes to self-perceptions. Controlled treatment trials examining outcomes related to self-perceptions were synthesised (k = 20, N = 2041), finding small reductions in both symptoms of depression (g =-0.30; 95 % CI:-0.52,-0.08) and self-perception outcomes (g = 0.33; 95 % CI: 0.16, 0.49) for interventions compared with control groups. Meta-regression analyses found no significant association between reductions in depressive symptoms and improvements in self-perception following treatment, suggesting that despite interventions generally improving both outcomes these changes may be unrelated to each other. Our results indicate that young people's self-perceptions are sensitive to change following treatment for depression, however effect sizes are small and treatments could be more effective in targeting and changing negative self-perceptions. Given the importance that young people place on integrating work on their sense of self into treatments for depression, future interventions could aim to support young people with depression to develop a positive sense of self.
