Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 21-item positive subscale from the extended Positive and Negative Affect Schedules | Post-intervention (2 weeks post-baseline) | The Joviality, Self-Assurance, Attentiveness, and Serenity subscales of the extended PANAS (PANAS-X; Watson & Clark, 1994) will be administered, following previous experimental research examining the effect of positive mental imagery on state mood (e.g. Holmes, Lang, & Shah, 2009). Participants will be asked to rate the items according to how they have been feeling 'in the past week, that is, during the past seven days, including today'. |

| Dimensional Anhedonia Rating Scale | Baseline, Post-intervention (2 weeks post-baseline), Follow-up (2 weeks after the post-intervention assessment) | An extended 26-item version of the Dimensional Anhedonia Rating Scale (DARS; Rizvi et al., 2015) will be administered. |
| GAD-7 | Baseline, Post-intervention (2 weeks post-baseline), Follow-up (2 weeks after the post-intervention assessment) | — |
Other
| Measure | Time frame | Description |
|---|---|---|
| Credibility/Expectancy Questionnaire | Baseline | — |
| Feedback Questionnaire | Follow-up (2 weeks after the post-intervention assessment) | — |
| Self-report mood/cognitions over the previous day (Likert scales) | Baseline, up to 2 weeks post-baseline | Ratings will be made up to 8 times over the two-week intervention period (between baseline and post-intervention) |
| State mood pre and post each training session (Likert scales) | Baseline, up to 2 weeks post-baseline | Ratings of state mood will be made pre and post each session of PMIT or CCT by participants in the Positive Mental Imagery Training and Cognitive Control Training arms. |
