[Subjective response to neuroleptic medication: a validation study of the Italian version of the Drug Attitude Inventory (DAI)].
OBJECTIVE
Aim of the study was to investigate the psychometric properties of the Italian version of the Drug Attitude Inventory (DAI) by exploring its construct validity.


METHODS
90 voluntary admitted patients with DSM III-R Schizophrenic (n.72) and Schizoaffective (n.18) disorders, age range between 18 and 50 years, treated with typical antipsychotics, able to participate in the study, were selected.


METHODS
Exploratory factor analyses with alpha factoring and maximum-likelihood methods with Varimax Rotation were used to analyse DAI scores.


RESULTS
Extraction methods found 7 factors which explained 62.5% of the total variance. The first 2 factors could be labelled as "subjective response to treatment" construct and factors 3 to 7 as "attitude to medication" construct.


CONCLUSIONS
Although preliminarily, the Italian version of the DAI seems to maintain the original psychometric properties and it can be used easily to get a valid measurement of the patients' attitude to neuroleptic medication.
