The authors adapted an imagery-based intervention to specifically target anhedonia by strengthening positive future imagery, self-compassion, and positive emotional experiences. The intervention was found to be feasible and acceptable for adolescents and was associated with substantial reductions in depressive symptoms that were maintained at follow-up. Improvements in anhedonia emerged more gradually, with larger gains observed three months after the intervention. Overall, the study provides promising preliminary evidence that positive mental imagery may be a useful early intervention target for adolescent depression and anhedonia.
