Note. All ESM predictors were person-mean-centered. Models with time-varying predictors include random slopes of those predictors (incl. quadratic variables). Models with lagged predictors include the lagged outcome as a predictor. Abbreviations: L=left, R=right, NAcc=Nuccleus Accumbens, MADRS= Montgomery-Asberg Depression Scale, IDS-SR=Inventory of Depressive Symptomatology - Self-Report, se=standard error, p=p-value, seML= standard error estimated using standard log likelihood procedure, serob=standard error estimated using the robust Huber-White sandwich estimation procedure, pML=p-value of effect based on the log-likelihood standard error estimation, prob=p-value of effect based on robust Huber-White sandwich estimation, qua=quadratic (referring to time-lagged quadratic effect of reward anticipation on activity pleasantness, lin=linear (referring to time-lagged linear effect of reward anticipation on activity pleasantness).
