Positive-affect treatment is useful inspiration, not app validation

Population and setting: 98 non-perinatal adults with low positive affect and depression/anxiety; fifteen therapy sessions.
What was found: Composite clinical improvement favored positive-affect treatment, with a small between-group advantage. Separate positive-affect and interviewer-anhedonia outcomes did not establish superiority.
Limits and applicability: Non-perinatal therapist-delivered intervention. No claim that a one-minute exercise duplicates it.
How directly does this apply?: non-perinatal; therapist-delivered
Gap between the study and our product: Design and measure anticipation, enjoyment and later recollection separately from depressive symptoms.
