Objective: A three-month prospective trial of a psychosocial intervention--customized adherence enhancement (CAE)--was conducted with 43 medication-nonadherent individuals with bipolar disorder.
Methods: CAE modules were administered as indicated by a screen that identifies reasons for nonadherence. The primary outcome was change in adherence to mood-stabilizing medications as measured by the Tablet Routines Questionnaire and pill counts. Secondary outcomes included change in symptoms, measured by the Hamilton Rating Scale for Depression (HAM-D), Young Mania Rating Scale (YMRS), and Brief Psychiatric Rating Scale (BPRS).
Results: Participants completed 76% of sessions. Dropout at three months was 13 (30%). Adherence improved from a baseline mean±SD of 34%±27% of tablets missed in the past month to only 10%±15% (p<.001). BPRS, HAM-D, andYMRS scores all indicated significant improvement at three-month follow-up (p<.05).
Conclusions: Although conclusions must be tempered by the uncontrolled design, CAE appeared to be well accepted and was associated with improvements in adherence, symptoms, and functioning.
