Non-compliance problems may rise to 50% among patients undergoing neuroleptic treatment. There are no direct measures available to predict compliance, if previous non-compliance is not taken into account. Attitudes towards neuroleptic treatment and insight into psychotic symptoms may vary during the course of the treatment process. It would be relevant to evaluate these items before taking any clinical action and later reassess the degree of change. The instrument thus far available has been the Drug Attitude Inventory. It has limitations for use with first-episode-patients and their follow-up. Its statements are dichotomous, which makes it difficult to determine the variation of attitudes e.g. during maintenance treatment, and most of the items concentrate on the subjective state of the patient, leaving attitudes as a minority in the scale. In this study, we report the new Attitudes towards Neuroleptic Treatment (ANT) questionnaire for the quantitative assessment of attitudes. We developed 10 statements for attitudes and two items for insight in the Visual Analogue Scale form (0-100 points). These were compared with the Drug Attitude Inventory 10 Questionnaire (DAI-10) (Hogan, T. P., Awad, A.G., Eastwood, R., 1983. A self-report scale predictive of drug compliance in schizophrenics: reliability and discriminative validity. Psychol. Med. 13, 177-183.) among 106 subjects receiving neuroleptic medication. The 12 Visual Analogue Scales showed a high inter-item consistency and fair test-retest validity. The results were in accordance with the DAI-10. The scales comprised three factors: general attitudes, subjective feeling and expectations and insight. Attitudes towards neuroleptic treatment and insight into psychotic symptoms are different dimensions and can be measured quantitatively. The Attitudes towards Neuroleptic Treatment scale is useful in assessing the state of attitudes before starting medication and for follow-up among patients receiving neuroleptic medication.
