A nurse-led psychoeducational program BalancingMySwing improves medication adherence among Taiwanese Han-Chinese with bipolar II disorderAuthor(s): Esther Ching-Lan Lin, Michael Berk, Pei-Chen Hsu and Ru-Band Lu
The beneficial effects of combined psychosocial and pharmacological treatments for bipolar disorder have been widely documented. However, little research has specifically looked at bipolar II disorder (BP-II), despite it being the most common variant.
This study used a matched-pairs two-group pretest–posttest design to compare the effectiveness of the 10-session weekly “BalancingMySwing” (BMS) program with treatment as usual in a Han Chinese cohort with bipolar II disorder. Twenty-four participants from a medical center in southern Taiwan with a DSM-IV diagnosis of BP-II were purposively recruited and divided into two matched-pair groups for treatment feasibility. Primary outcome indicators were medication adherence and mood symptoms, which were assessed at baseline and posttreatment. Medication adherence was assessed using the self-reported Medication Adherence Rating Scale (MARS). Mood symptoms were assessed by a blinded rater using the 11-item Young Mania Rating Scale (YMRS) and 17-item Hamilton Depression Rating Scale (HDRS).
After 10 weeks, a significant group × time interactions for the MARS scores indicated that improvements in medication adherence were greater in the BMS group than in the Treatmentas- Usual (TAU) group. However, there were no significant time effects or group differences for the HDRS or the YMRS scores in either group.
Our data support the potential beneficial effects of the nurse-led psychoeducational program on medication adherence in Taiwanese Han Chinese with BP-II. Several limitations and barriers to implementation that might confound results are discussed. Future studies with larger samples and longer follow-ups are needed.
