^aTime-lagged predictors of engagement in social company in the whole sample, controls, moderate depression, and high depression groups. Time-lagged logistic regressions, n = number of assessments. Social versus nonsocial activity outcomes were coded as 1 and 0, respectively. Controlled for assessment time and mood (negative affect and positive affect). When age and assessment period were added as extra covariates, results remained the same.

^bC: controls.

^cMD: moderate.

^dHD: high.
