Background: Poor treatment adherence among patients with bipolar disorder (BD) is a common clinical problem. However, whether adherence is mostly determined by patient characteristics or attitudes, type of treatment or treatment side effects remains poorly known. Methods: The Jorvi Bipolar Study (JoBS) is a naturalistic prospective 18 month study representing psychiatric in and outpatients with DSM-lV BD I and II in three Finnish cities. During the 18-month follow-up we investigated the continuity of, attitudes towards and adherence to various types of psychopharmacological and psychosocial treatments among 168 psychiatric in and outpatients with BD I or II. Results: One-quarter of the patients using mood stabilizers or atypical antipsychotics discontinued medication during at least one treatment phase of the follow-up autonomously, mostly during depression. When pharmacotherapy continued, adherence was compromised in one-third. Rates of non-adherence to mood stabilizers or antipsychotics did not differ, but the predictors did. One-quarter of the patients receiving psychosocial treatments were non-adherent to them. Limitations: Serum concentrations were not estimated. Conclusions: More than one-half of BD patients either discontinue pharmacotherapy or use it irregularly. Autonomous discontinuation takes place mostly in depression. Although rates of non-adherence do not necessarily differ between mood-stabilizing medications, the predictors for nonadherence do. Moreover, adherence to one medication does not guarantee adherence to another, nor does adherence at one time-point ensure later adherence. Attitudes towards treatments affect adherence to medications as well as to psychosocial treatments and should be repeatedly monitored. Non-adherence to psychosocial treatment should be given more attention. (C) 2013 Elsevier B.V. All rights reserved.
