Rates and Predictors of Adherence with Atypical Antipsychotic Medication: AFollow-Up Study of Adolescent Inpatients

Failure to continue recommended treatment with atypical antipsychotics was most common in cases who did not comply with other aspects of the discharge plan. Efficacy of the medication did not predict nonadherence, as half of the noncompliant subjects stated that the medication had been helpful. Rapid weight gain also predicted nonadherence, but subjective impression of long-term weight gain was not different across adherence or treatment status. These data tentatively suggest that in adolescent patients, tendencies toward general uncooperativeness and substance abuse may be at least as important as the occurrence of common side effects in the determination of medication adherence.
