Randomization was performed using a computer-generated random number table. Each participant was assigned a unique identification code, and allocation to the study groups was carried out according to the predetermined random sequence. To ensure balanced group sizes, participant allocation continued until 26 individuals were assigned to each group. The allocation list was maintained by the principal investigator, and all outcome assessments were conducted at baseline (pretest), post-intervention (posttest), and the three-month follow-up according to the assigned group, Blinding description: Allocation and sessions were conducted under blinding by a clinical supervisor.

The sessions covered the six core ACT processes, including acceptance, cognitive defusion, present-moment awareness, self-as-context, values clarification, and committed action. Homework assignments and experiential exercises were provided at the end of each session to facilitate the application of therapeutic skills in daily life. The total duration of the intervention was 8 weeks. No medications or medical devices were used during the intervention. Intervention 2: Control group: Participants in the control group did not receive Acceptance and Commitment Therapy during the study period and continued to receive routine care, if needed.
