Adult outcomes included the Patient Health Questionnaire (PHQ-4), DSM-5 Cross-Cutting Symptom Measure (DSM-5 CC), and Personality Inventory for DSM-5 (PID-5).

Gender differences were observed in the well-being and health dimensions, while all dimensions except support showed significant differences based on age group. The care unit location also revealed significant differences across all dimensions.
