^aTime-lagged predictors of enjoyment of activities in the whole sample, controls, moderate depression, and high depression groups. Time-lagged linear regressions, n = number of assessments. 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.
