Assessing adult adjustment to relationship separation: The Psychological Adjustment to Separation Test (PAST)

Relationship separation is associated with substantial adult adjustment problems. The Psychological Adjustment to Separation Test (PAST) was developed as a self-report measure of 3 key dimensions of separation adjustment problems: lonely negativity, ex-partner attachment and coparenting conflict. Two independent samples (n = 219 and n = 169, respectively) of recently separated adults, 60% of whom had children, completed the PAST and other measures of general adjustment. Exploratory and confirmatory factor analyses demonstrated a replicable 3-factor structure, with each factor showing satisfactory test–retest and internal reliability and good convergent and discriminant validity. The PAST meets initial criteria for a potentially useful new measure of adult separation adjustment
