Escala de Adesão à Medicação Anti-PsicóticaGeneral Description
The Antipsychotic Medication Adherence Scale (AMAS) was designed to measure medication adherence in individuals with psychotic spectrum disorders. The final version of the scale ended up with 13 statements tapping into clinical (e.g., “When I take this medication, I can think in a clearer manner”), psychosocial (e.g., “I’m ashamed of taking this medication”) and practical factors (e.g., “I find it difficult to take the medication as recommended by the doctor”) recognized as key predictors of medication adherence. Participants are invited to rate the extent to which they agree with each statement using a 5-point Likert scale from 0 (completely disagree) to 4 (completely agree). This scale is designed for higher results to reflect greater adherence to antipsychotic medication. Results indicated a two-factor solution: “Barriers to adherence” and “Positive beliefs about medication”.
