NCT07661225

Brief Summary

This randomized controlled trial aims to evaluate the effect of Acceptance and Commitment Therapy (ACT)-based nursing interventions on social cognition, emotion regulation, and psychological flexibility in individuals diagnosed with schizophrenia. The study will be conducted at Erzincan Community Mental Health Center (TRSM) between October 2026 and January 2027. A total of 64 participants (32 experimental, 32 control) will be recruited from schizophrenia patients registered at the center. The experimental group will receive 8 structured group sessions based on ACT principles integrated into nursing practice (45-60 minutes per session, once weekly), while the control group will receive routine care only. Pre-test and post-test measurements will be obtained using the Observable Social Cognition Rating Scale (OSCARS), the Difficulties in Emotion Regulation Scale-Brief Form (DERS-16), and the Acceptance and Action Questionnaire-II (AAQ-II).

Outcome Measures

Primary Outcomes (3)

  • Social Cognition

    Change in social cognition as measured by the Observable Social Cognition-A Rating Scale (OSCARS). OSCARS is an 8-item interviewer-rated scale assessing social cognitive impairments in schizophrenia on a 7-point Likert scale (1 = None, 7 = Extreme). Higher scores indicate greater impairment. Total scores range from 8 to 56.

    Baseline (before Session 1, Week 0) and immediately following Session 8 (Week 8)

  • Emotion Regulation

    Change in emotion regulation difficulties as measured by the Difficulties in Emotion Regulation Scale-Brief Form (DERS-16). DERS-16 is a 16-item self-report scale scored on a 5-point Likert scale (1 = Almost never, 5 = Almost always). Total scores range from 16 to 80; higher scores indicate greater difficulty in emotion regulation. There is no established cut-off score.

    Baseline (before Session 1, Week 0) and immediately following Session 8 (Week 8)

  • Psychological Flexibility

    Change in psychological flexibility/experiential avoidance as measured by the Acceptance and Action Questionnaire-II (AAQ-II). AAQ-II is a 7-item self-report scale scored on a 7-point Likert scale (1 = Never true, 7 = Always true). Total scores range from 7 to 49; higher scores indicate greater experiential avoidance and psychological inflexibility.

    Baseline (before Session 1, Week 0) and immediately following Session 8 (Week 8)

Study Arms (2)

Acceptance and Commitment Therapy (ACT)-Based Nursing Intervention

EXPERIMENTAL

32 individuals diagnosed with schizophrenia and registered at Erzincan TRSM who meet inclusion criteria and provide written informed consent, assigned through computer-based simple randomization. The experimental group will receive 8 structured weekly group sessions (45-60 min) based on Acceptance and Commitment Therapy (ACT) principles integrated into nursing practice. Sessions are organized around the six core ACT processes: present-moment contact, acceptance, cognitive defusion, self-as-context, values clarification, and committed action. Each session follows a standard flow: review of previous session and homework, mindfulness exercise, ACT-based content and experiential exercises, homework assignment, and feedback. Participants will be divided into 3 subgroups (11/11/10 persons). Content validity of the program will be established by expert review (≥5 experts in psychiatric nursing, psychology, and psychiatry) prior to implementation.

Behavioral: Acceptance and Commitment Therapy (ACT)-Based Nursing Intervention

Routine Care Control Group

NO INTERVENTION

32 individuals diagnosed with schizophrenia and registered at Erzincan TRSM who meet inclusion criteria and provide written informed consent, assigned through computer-based simple randomization. The control group will receive routine care only during the study period. After post-test data collection is completed, participants in the control group will receive a condensed 2-session ACT-based nursing intervention as an ethical courtesy to ensure equitable benefit.

Interventions

This intervention consists of an 8-session, structured, Acceptance and Commitment Therapy (ACT)-based psychosocial nursing program. The sessions will be conducted by a trained researcher in a group format. Each session will last approximately 60 to 90 minutes and will be held on a weekly basis. The program is specifically tailored for individuals diagnosed with schizophrenia and focuses on the core processes of the ACT hexaflex model, including mindfulness, cognitive defusion, acceptance, and values-based actions to improve social cognition, emotion regulation, and psychological flexibility.
