Brief Summary

The purpose of this randomized controlled clinical trial is to evaluate the effectiveness of an Acceptance and Commitment Therapy (ACT)-oriented psychoeducation program based on the Tidal Model in patients diagnosed with depression who are receiving transcranial magnetic stimulation (TMS) treatment at a university hospital psychiatry clinic. The primary objective of this study is to determine whether participation in the psychoeducation program improves meaning in life and conscious self-care compared to usual treatment alone. The main questions this study aims to answer are:

• Does the ACT-oriented psychoeducation program increase participants' level of meaning in life?
• Does the program improve conscious self-care behaviors in individuals with depression? Participants will be randomly assigned to either an intervention group or a control group. The intervention group will receive an 8-week structured psychoeducation program in addition to standard TMS treatment. The control group will continue to receive standard treatment without additional psychoeducation. Participants in the intervention group will attend weekly psychoeducation sessions focusing on psychological flexibility, values clarification, coping strategies, and self-care practices. Outcome measures will be collected at baseline, immediately after the intervention, and one month after completion of the program.

Outcome Measures

Primary Outcomes (1)

• Meaning in Life

  Measured using the Meaning in Life Questionnaire (MLQ) to assess changes in participants' perceived meaning and purpose in life.

  Baseline (pre-intervention) to immediately post-intervention (8 weeks), and 1-month follow-up

Study Arms (2)

Control group receiving standard treatment (n=23)

NO INTERVENTION

Participants receive standard Transcranial Magnetic Stimulation (TMS) treatment only, without additional psychoeducation or behavioral intervention.

Experimental group receiving ACT based on Tidal Model (n=23)

EXPERIMENTAL

Participants in the experimental group receive 8-session Acceptance and Commitment Therapy (ACT)-based psychoeducation, structured within the Tidal Model, in addition to standard Transcranial Magnetic Stimulation (TMS) treatment. The program is designed to enhance meaning in life and conscious self-care. Total participants: 23.

Behavioral: Tidal Model-based ACT

Interventions

Tidal Model-based ACT BEHAVIORAL

This intervention combines standard Transcranial Magnetic Stimulation (TMS) treatment with an 8-session Acceptance and Commitment Therapy (ACT)-based psychoeducation program structured specifically within the Tidal Model framework. Unlike standard ACT or TMS interventions alone, this program integrates mindfulness, value-based actions, and experiential exercises tailored for patients with depression receiving TMS, aiming to enhance meaning in life and conscious self-care.
