Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Behavioral activation | Change through study completion, an average of 31 days. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline vs posttreatment) | In a scale from 0 (not at all) to 6 (completely), to what extent were you satisfied with what you did today? |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Mood | Change through study completion, an average of 31 days. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | In a scale from 0 (completely sad) to 100 (completely happy), how did you feel today? |
| Change in Depression | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | In a scale from 0 (not at all) to 3 (completely), how was your level of depression today? |
| Change in Positive affect | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | In a scale from 1 (not at all) to 5 (completely), how was your positive affect today? |
| Change in Negative affect | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | In a scale from 1 (not at all) to 5 (completely), how was your negative affect today? |
| Change in Activity level | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | In a scale from 0 (minimum) to 100 (maximum), what was your activity level today? |
