Medication Adherence and Compliance

The purpose of this study was to develop and test a brief scale (Brief Evaluation of Medication Influences and Beliefs [BEMIB]) designed to identify patients who are more likely to be nonadherent to their antipsychotic medication.Sixty-three outpatients with schizophrenia and related psychotic disorders were enrolled and given an assessment battery including the BEMIB, a previously published adherence scale, extrapyramidal symptom rating scales, and an adherence assessment with patient self-report and prescription refill records. The BEMIB consisted of 8 statements derived from the health belief model with a 5-point Likert-type scale for each statement. Subjects chose a single answer for each item depending on their level of agreement or disagreement.According to refill records, subjects meeting BEMIB-based criteria for nonadherence had significantly larger gaps in antipsychotic therapy (greater nonadherence) compared with those of participants not meeting criteria for nonadherence. For the 1-week test-retest reliability, the BEMIB total score and 5 of 8 single items correlated significantly. BEMIB total scores correlated significantly with an established assessment of adherence (Drug Attitude Inventory), demonstrating adequate construct validity.The BEMIB represents a promising scale for identifying patients more likely to be nonadherent to their medications.
