Modification of an Intervention to Improve Adherence in Adolescents and Young Adults With Bipolar Disorder.

Objective: Managing bipolar disorder (BD) is particularly challenging for adolescents and young adults (AYAs) ages 16 to 21. Few interventions exist that address self-management in AYAs with BD. Thus, this study aimed to modify the customized adherence enhancement behavioral intervention for AYAs through an iterative, patient-centered process. Method: The Obesity-Related Behavioral Intervention Trials (ORBIT) model was used for intervention development. In phase 1a, adherence barriers and facilitators were identified to refine intervention content. Phase 1b occurred following curriculum modification to ensure that the modified intervention was relevant and usable by the target population. Data were collected via focus groups and interviews with AYAs with BD, parents, and providers. Transcripts were analyzed using directed content analysis. Results: Phase 1a included focus groups/interviews with AYAs (n = 10), parents (n = 4), and providers (n = 9) who described the difficulties and successes in managing BD symptoms, improving adherence, and transitioning care from caregivers. Phase 1b included an advisory board composed of 8 phase 1a participants who provided feedback on modified session activities, module delivery, and curriculum. Phase 1b involved usability testing with new participants (n = 8), revealing the need for modifiable language based on developmental level, more engaging visual images, and confirmation that topics were salient to AYAs with BD. Conclusion: Though sample sizes were small and not representative of the population of AYAs with BD, the ORBIT methodology informed the adaptation of the customized adherence enhancement intervention to improve adherence in AYAs with BD. Important next steps are to conduct a pilot randomized clinical trial of customized adherence enhancement for AYAs.

Association Between Symptom Severity and Medication Adherence in Adolescents with Bipolar Disorder Demonstrating Suboptimal Adherence.

Objective: While medication non-adherence is common in bipolar disorder (BD), few studies have specifically assessed non-adherent BD adolescents and young adults (AYAs). This analysis, using screening and baseline data from an ongoing randomized controlled trial, examined the relationship between BD symptoms and adherence in poorly adherent AYAs. Methods: AYAs ages 13-21 had sub-optimal adherence defined as missing ⩾ 20% of prescribed BD medication. Mean sample (N = 36) age was 19.1 years (SD = 2.0), 66.7 % (N = 24) female, 25.0 % (n = 9) non-white. Adherence was measured via: 1) self-reported Tablets Routine Questionnaire (TRQ) and 2) electronic monitoring (SimpleMed pillbox). Symptoms were measured with the Hamilton Depression Rating Scale (HAM-D), the Young Mania Rating Scale (YMRS), and the Clinical Global Impression Scale (CGI). Results: Mean percentage of missed BD medications using TRQ was 34.9 (SD = 28.9) at screening and 30.6 (SD = 33.0) at baseline. Mean percentage of missed medication using SimpleMed at baseline was 42.1 (SD = 37.0). The correlation between TRQ and SimpleMed was r = 0.36 (p = 0. 13). Neither CGI nor age were correlated with adherence. Neither TRQ nor SimpleMed were significantly related to HAM-D. YMRS was positively associated with worse adherence for TRQ (r = 0.36, p = 0.03), but not significantly associated with SimpleMed. Adherence did not differ by other demographic attributes. Conclusion: Adherence levels varied widely in AYA with BD. Adherence monitoring increased adherence by approximately 4.5%, and use of electronic pill monitoring identified a greater proportion of missed medication vs. self-report. BD symptoms may not consistently identify AYA with adherence challenges.

A customized adherence enhancement program for adolescents and young adults with suboptimal adherence and bipolar disorder: Trial design and methodological report.

BACKGROUND: The onset of bipolar disorder (BD) is common during late adolescence and young adulthood (AYA). Suboptimal medication adherence is a critical yet modifiable risk factor for negative outcomes among AYAs with BD. METHODS: This research used an iterative process (e.g., focus groups, advisory board, cognitive interviews) to modify an existing adherence intervention to address suboptimal adherence in AYAs with BD. The modified version of Customized Adherence Enhancement for Adolescents and Young Adults (CAE-AYA) will be compared to an Enhanced Treatment as Usual condition (ETAU) in 40 AYAs intervention using a 6-month prospective, randomized controlled trial (RCT) in a high-risk group of 16-21 year old AYAs with BD with demonstrated non-adherence to their prescribed BD medications. CONCLUSIONS: This report describes the methodology and design of the ImprovinG adhereNce In adolescenTs with bipolar disordEr (IGNITE) study. If successful, the CAE-AYA approach has the potential to advance care for vulnerable youth with BD.
