Non-adherence is a problem throughout medicine and there are many strategies that are used to improve antipsychotic adherence. A review of the literature identified 33 commonly cited strategies for enhancing consumer adherence. Three core themes were identified: Information/Education; Behavioural strategies; and Cognitive/Motivational strategies.

To develop the Portuguese version of the DIAS.

The DIAS was translated and adapted for Portuguese language. The translation was done by the first author (AC). The accuracy of this translation was discussed in a two focus group of experts, providing opinion on face and content validity. The participants were asked to rate how often they had difficulties using each of the 33 strategies with consumers who were non-adherent. A four point Likert scale was used (1 = never; 4 = always) such that higher scores indicated more frequent difficulty using the strategy.

A convenience sample of 65 mental health professionals working in a variety of settings is being collected. The average score in DIAS was 85.0 (SD14.6). The value of internal reliability coefficient α was 0.93. The intraclass correlation coefficient of total MABQ score was 0.45. The t-test showed that there were no statistically significant differences between the mean values of the measurement scale at two different times (84.5 vs.90.5; P = 0.04).

Interventions to improve antipsychotic adherence would benefit from further research. However, it is important always to bear in mind that none of these strategies can be a substitute a positive therapeutic alliance. The Portuguese version of DIAS will provide professionals with a new tool to evaluate the frequency how strategies are implemented and the impact of each strategy in treatment adherence.
