Longitudinal data assessing self-concept clarity, dissociation, self-criticism, anxiety and psychological distress

Description

Undergraduate students filled online questionnaires at base line (N=200) and 3 months later (N=157) assessing dissociative experiences, self-concept clarity, self-criticism, anxiety, COVID-19 anxiety, psychological distress, childhood trauma and demographic information. Dissociation variables (total score and subscales) and the BAI score were skewed at both Time 1 and Time 2, and therefore were transformed using squared root (total DES and BAI score at both Time 1 and Time 2) or log10 (ABS, DEP/DER and AMN at both Time 1 and Time 2) transformations. Univariate outliers were substituted by one unit of measurement above the next highest value.
