Additional results pertaining to secondary outcome measure and the relation between PHQ-9 and daily mood changes.
| Secondary outcome measure (N = 137) | Estimate | SE | p-value | 95% CI |
|---|---|---|---|---|
| PHQ-9 post score | −0.20 | 1.12 | 0.86 | (−2.41, 2.01) |
| ∆PHQ-9 score | 0.12 | 1.17 | 0.91 | (−2.18, 2.44) |
| PHQ-9 and daily mood changes (N = 55) | Estimate | SE | p-value | 95% CI |
| Happy vs Neutral | −0.17 | 0.22 | 0.43 | (−0.61, 0.26) |
| Sad vs Neutral | 0.83 | 0.23 | 0.001 | (0.38, 1.29) |
| Sad vs Happy | 1.04 | 0.2 | ⩽ 0.01 | (0.63, 1.45) |
PHQ: Patient Health Questionnaire; CI: confidence interval.
Regressions control for age and nationality. For PHQ-9 post score as the outcome variable, we also control for PHQ-9 pre score. A lower PHQ-9 post score points to a decrease in depressive symptoms.
