app based treatment of Misophonia and implications of a lack of mediation effects

In a 2025 RCT, Podoly et al. tested a 15-day mHealth intervention (GGanger) targeting anger-related cognitions in 85 adults with misophonia, comparing immediate vs delayed app use across baseline, post, and 1-month follow-up. The intervention reduced anger rumination, metacognitions, and one misophonia measure relative to control, with broader within-group improvements maintained after app use. Mediation was not supported, suggesting symptom reduction may reflect mechanisms beyond the targeted cognitive processes. From this the authors claim the GGanger shows promise as a scalable, low-cost intervention for misophonia symptoms and anger-related cognitions, but that the mechanisms underlying symptom reduction remain unclear and may involve cognitive processes beyond those specifically measured in this study.
