Disability in clinically stable patients of schizophrenia

Disability associated with schizophrenia affects every aspect of life. In India, persons with schizophrenia are eligible for disability benefits. Only a handful of patients are aware and able to avail the benefits. We intended to assess disability in clinically stable patients of schizophrenia as even though they are stable but are disabled and may benefit from disability benefits and rehabilitation.

Sixty-two clinically stable patients of schizophrenia were assessed on the Mini-International Neuropsychiatric Interview, Positive and Negative Syndrome Scale (PANSS), and Schizophrenia Cognition Rating Scale. Disability was assessed on the Indian Disability Evaluation and Assessment Scale (IDEAS).

Nearly one-fourth of the "stable patients" had moderate-to-severe disability (22.6% - moderate and 1.6% - severe), i.e., certifiable disability as per IDEAS. Disability had a significant correlation with all three domains of PANSS as well as total PANSS score. The correlation was stronger with negative than with positive symptom scores. Disability also strongly correlated with cognitive impairment. "Work," "communication and understanding," and "interpersonal relationship" domains of IDEAS had a strong correlation with cognitive impairment.

Nearly 25% of the stable patients had certifiable disability. The "work" domain of IDEAS was most affected. It demonstrates that the rehabilitation of this population may contribute to reducing disability.
