Psychological Interventions for Negative Symptoms of Schizophrenia
摘要
Negative symptoms are among the most disabling aspects of schizophreniaoften persisting despite pharmacological treatment and contributing significantly to poor functional outcomes. In recent years, psychological interventions have emerged as essential tools for targeting these symptoms. Cognitive behavioural therapy (CBT) is the most widely studied approach, showing modest but consistent benefits in improving motivation and social functioning. More targeted interventions, such as the cognitive behavioural social skills training (CBSST) and the motivation and enhancement training (MOVE), have demonstrated promise in addressing low functioning . Cognitive Remediation Therapy (CRT) has been effective in improving cognitive domains associated with negative symptoms, particularly when combined with functional skills training. Emerging strategies, including behavioural activation, mindfulness-based approaches, and motivational interviewing, are gaining traction as adjunctive therapies. Despite encouraging evidence, the heterogeneity of negative symptoms and overlap with cognitive and depressive features pose challenges in treatment design and outcome measurement. Personalized, multi-component interventions that integrate psychological therapies with functional and vocational support show the greatest potential for sustained improvement. Continued research is needed to refine these approaches and identify predictors of treatment response to optimize care for individuals with schizophrenia.
