Patients' subjective experiences of antipsychotics - Clinical relevance

The subjective experience of patients with schizophrenia who are receiving antipsychotic medication has been a neglected research area, as has the satisfaction of patients with their drug treatments. This is unfortunate, as satisfaction with treatment appears to be related strongly to the readiness of patients to take their medication as prescribed, and thereby to outcome. Patients' perceptions of their treatment do not appear to be related strongly to severity of illness or symptom ratings, although there are associations between perceptions of treatment and adverse effects. Surveys of patient experience with typical antipsychotics have tended to indicate high levels of dissatisfaction and perceived adverse effects. There have been a number of surveys of patients' perceptions of treatment with the atypical antipsychotics. These tend to accord with the expectation that a relative freedom from adverse effects with the atypical antipsychotics will be reflected in enhanced levels of satisfaction and perceived well-being. In general, these studies share a number of weaknesses, including small sample sizes, bias in selection of respondents, open treatment and lack of suitable comparator groups. In addition, many have adopted a cross-sectional, rather than longitudinal, approach and have relied on nonvalidated and perhaps idiosyncratic rating measures. Recently, there have been studies of better methodological quality. These, too, have indicated that patients regard the newer treatments more positively than the older regimens. In addition, there is now evidence that the various new-generation antipsychotics may be evaluated differently by patients.
