| Experimental: Activities.<br>Increasing activity level included a brief description of how activities affect mood. Participants were then asked to choose the activities they could use to improve their mood from an available list of helpful activities; users were also able to generate their own helpful activities. Participants were also presented with examples of unhelpful activities such as staying in bed and being isolated. | Behavioral: Activities.<br>* Increasing activity level included a brief description of how activities affect mood.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Patient Health Questionnaire (PHQ-9; Kroenke & Spitzer, 2002) scores | Which is a widely used 10-item measure that screens for a presence of a major depressive episode as well as assesses the severity of depressive symptomatology over a 2-week period. | Baseline - 1 week follow-up | 

Secondary Outcome Measures
