Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in positive emotional response as measured by ecological momentary assessment | Baseline, up to 6 months | Emotional response will be measured by computing a total mean score of "happy", "excited", "content", "attentive", "relaxed". The total mean score ranges from 0 to 100, with higher scores indicating greater positive emotional response. |
