CTQ, Childhood Trauma Questionnaire; SLE, Stressful Life Events; ICC, Intraclass Correlation Coefficient; SD_B-S, Between-subject standard deviation; SD_W-S, Within-subject standard deviation. Between-subject correlations are presented above the diagonal; within-subject correlations among momentary measures are presented below the diagonal. Given that CTQ and SLE represent single time-point scores as cross-sectional data, no within-subject correlations between trait and state measures could be computed. Means and between-subject standard deviations were calculated based on aggregated person-mean scores.

^aCortisol data were log-transformed and winsorized to three standard deviations of the sample mean.
