ACT combined with stratified intervention improved cognitive function and quality of life in elderly schizophrenia patients by enhancing psychological flexibility and family support.
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).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| the conventional treatment group | Other | 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. |
|
| the ACT group | Other | 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. |
