Abstract: Introduction: Atypical antipsychotic drugs, with superior tolerability and possibly superior efficacy, were expected to give schizophrenia patients better quality of life (QOL) than conventional treatment. Research findings are equivocal. Method: We evaluated QOL using three subjective measures – Drug Attitude Inventory (DAI); Sickness Impact Profile (SIP); Schizophrenia Quality of Life Scale (SQLS) – in 126 routinely seen patients whose treatment was stable for six months, regardless of co-morbidity, current clinical status and concomitant medications. Severity of disorder was assessed with the Global Assessment Schedule (GAS). Results: Fifty patients were on conventional treatment and 76 on atypical treatment. Atypical patients were more likely to be abusing substances ( p = 0.02) and living independently ( p = 0.00). Conventionally treated patients were older than atypically treated patients. Conventionally treated patients suffered schizophrenia almost twice as long as atypically treated patients. Atypically treated patients enjoyed substantially better quality of life than conventionally treated patients on all measures. The effects of confounding variables, i.e. age, duration, accommodation, co-morbid substance misuse and time spent in hospital, were evaluated with the General Linear Model. This confirmed the status of drug treatment as the primary predictor of all aspects of QOL. Conclusion: We conclude that quality of life is genuinely superior on atypical treatment even allowing for the confounding effects of differential prescribing habits: atypical treatment tends to be reserved for younger, less seriously ill patients. There is no scientific or clinical rationale to support this practice.
