Note. Cronbach's alpha for month‐level variables are averaged over measurement occasions. Gender: 0 = female, 1 = male; Children: 0 = living without children, 1 = living with children; Group: 0 = control group, 1 = intervention group. Correlations below the diagonal are person‐level correlations (N = 348–516) with correlations r ≥ .10 being significant at p < .05 and r ≥ .12 being significant at p < .01. Correlations above the diagonal are month‐level correlations (N = 1382–1721) with correlations r ≥ 09 being significant at p < .01.
