Schizophrenia Disorders, Cognitive Impairment, Acceptance and Commitment Therapy
Conditions
Brief summary
ACT combined with stratified intervention improved cognitive function and quality of life in elderly schizophrenia patients by enhancing psychological flexibility and family support.
Detailed description
This study analyzes factors influencing cognitive impairment and evaluates the efficacy of a stratified intervention combining Acceptance and Commitment Therapy (ACT) with these factors to improve cognitive function and quality of life. A total of 149 elderly patients with schizophrenia were enrolled, split into cognitive impairment (n = 86) and non-cognitive impairment (n = 63) groups. A combined case-control and randomized controlled trial design was employed. Logistic regression was used to identify independent risk factors. Cognitive impairment patients were randomly assigned to either the conventional treatment group (n = 39) or the ACT group (n = 39) for a 6-week intervention. Evaluation instruments included the AAQ-II (psychological flexibility), GSES (self-efficacy), FACES II-CV (family functioning), SSMI-C (internalized stigma), and SQLS (quality of life).
Interventions
Patients received conventional mental health education once weekly for 6 weeks, covering schizophrenia symptoms, treatment, and prognosis. Standard nursing care and antipsychotic medications (e.g., olanzapine, quetiapine) were maintained without additional psychological interventions.
Patients received ACT-based nursing interventions tailored to risk factors (e.g., age ≥70, long disease duration), including: ACT modules: Acceptance, cognitive defusion, mindfulness, values clarification, and committed action. Adjunct strategies: Family therapy, Tai Chi, and crisis planning. Frequency: Daily practice + 1-2 group sessions/week for 6 weeks. Goal: Enhance psychological flexibility, reduce stigma, and improve cognitive function.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Cognitive Function | Baseline to 6 weeks post-intervention | Improvement in global cognitive function assessed via the Montreal Cognitive Assessment (MoCA), focusing on memory, attention, and executive function. Higher scores indicate better cognition (range: 0-30). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Psychological Flexibility (AAQ-II) | Baseline to 6 weeks. | Scores on the Acceptance and Action Questionnaire-II (7 items, Likert scale 1-7). Lower scores indicate greater flexibility. |
| Self-Efficacy (GSES) | Baseline to 6 weeks. | General Self-Efficacy Scale (10 items, scores 10-40). Higher scores reflect stronger self-efficacy. |
| Family Functioning (FACES II-CV) | Baseline to 6 weeks. | Family Adaptability and Cohesion Evaluation Scale (cohesion + adaptability subscales). Higher scores indicate healthier family dynamics. |
| Stigma Reduction (SSMI-C) | Baseline to 6 weeks. | Stigma Scale for Mental Illness (28 items). Lower scores on Discrimination/Illness Concealment subscales indicate reduced stigma. |
| Quality of Life (SQLS) | Baseline to 6 weeks. | Schizophrenia Quality of Life Scale (30 items). Lower scores indicate better QoL in psychosocial, motivation, and symptom domains. |
