Predictive value of symptoms for quality of life in first-episode schizophrenia

摘要

Background: Management of the disease symptomatology impacts the long-term functioning and quality of life (QOL) in psychotic patients. Aim: The aim of this research was to study the association between psychiatric symptoms (positive, negative and general psychopathology symptoms) and QOL in first-episode schizophrenia patients. Methods: Fifty-five first-episode drug-naive schizophrenia outpatients were recruited from a tertiary care hospital in New Delhi, India. WHOQOL-Bref (World Health Organization Quality of Life) Scale was used to assess multi-dimensional domains of QOL (physical, psychological, social and environmental health). The patients were evaluated clinically using PANSS and followed up for 6 months. Multivariate analyses were carried out to outline the symptoms which are predictive of QOL in these patients. Results: Physical well-being as assessed with WHOQOL-Bref is significantly impacted by the positive, negative and general psychopathology symptoms of the disease. General psychopathology symptoms demonstrated a strong relationship with different facets of QOL. These symptoms are predictive of physical (P = 0.025) and psychological health (P = 0.026), social relationships (P = 0.009) and environmental QOL (P = 0.022). Conclusions: The general psychopathology symptoms significantly impact QOL in a diverse manner. Negative symptoms have a greater influence than positive symptoms on subjective QOL. Clinical implications: The antipsychotics focus on primary positive and negative disease symptoms. There is a need to develop a holistic approach (target non-psychotic symptoms intensively) in the disease management to prevent further long-term impairment of QOL.
