Participants will be assessed using standard clinical rating scales to evaluate depressive symptoms, anxiety, substance use, and quality of life. There is no additional financial burden or risk to the participants. All information collected will be kept confidential. Participation in the study is voluntary, and participants may withdraw at any time without affecting their ongoing treatment.
