Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Patient Health Questionnaire-9 (PHQ-9) | Depression questionnaire. Scores range from 0 to 27. Lower scores indicate less depression. | Up to 8 weeks post-intervention | 
| Change in Generalized Anxiety Disorder Screener-7 (GAD-7) | Anxiety questionnaire. Total scores range from 0-21. Lower scores indicate less anxiety. | Up to 8 weeks post-intervention | 
| Change in the Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS) | Well-being questionnaire. Total scores range from 7 to 35. Higher values indicate higher well-being scores. | Up to 8 weeks post-intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ratings on the Acceptability of Intervention Measure (AIM) | Questionnaire measuring the acceptability of an intervention. Acceptability refers to the perception that a given treatment is agreeable or satisfactory. The total score ranges from 4 to 20. Higher scores indicate higher acceptability ratings. | Immediately after the intervention | 
| Ratings on the Intervention Appropriateness Measure (IAM) | Questionnaire measuring the appropriateness of an intervention. Appropriateness refers to the perceived fit or relevance of an intervention. The total score ranges from 4 to 20. Higher scores indicate higher appropriateness. | Immediately after the intervention | 
| Mechanisms of Change | Participants answered questions relating to each module's mechanism of change on a 7-point Likert Scale, from strongly disagree to strongly agree. Specifically, we asked participants: How capable they feel about managing negative thoughts; If they will intentionally spend time doing activities they enjoy; If they will notice and appreciate good things; If they will | Up to 8 weeks post-intervention | 
| Secondary Control | We asked participants three items to assess secondary control (Weisz et al., 2010). The items are scored on a 4-point Likert scale, ranging from 0 (Very false) to 3 (Very true). The three items are: When something bad happens, I can find a way to think about it that makes me feel better. After a really hard day, I can make myself feel better by remembering some good things that happened. When bad things happen to me that I can't control, there are lots of things I can do to feel better. Higher scores indicate greater secondary control. | Up to 8 weeks post-intervention | 
| Positive and Negative Affect Schedule | Questionnaire measuring positive affect and negative affect. Scores on the positive affect subscale range from 10-50, with higher scores representing higher levels of positive affect. Scores on the negative affect subscale range from 10-50, with lower scores representing lower levels of negative affect. | Up to 8 weeks post-intervention | 
| Perceived Stress Scale-4 | Questionnaire measuring perceived stress. Scores range from 0-16, with higher scores indicating greater stress. | Up to 8 weeks post-intervention |
