RESUMEN
Background : Depressive symptoms in middle-aged and older age bipolar disorder (BD) are associated with decreased quality of life and premature mortality. Yet, currently available pharmacological treatments are limited in efficacy. Mind-body interventions have been shown to improve mood, quality of life, and cognition in other adult populations, and may thus provide a promising therapeutic alternative. Here we conduct the first randomized controlled trial (RCT) examining the efficacy of a group Qigong/Tai Chi intervention (QT-BD) for reducing depressive symptoms in middle-aged and older adults with BD. As a further innovation during the COVID pandemic, we used Zoom to deliver the group intervention and active control. Methods : We conducted a virtually-delivered 12-week pilot RCT with 23 patients with BD aged >= 40 comparing a QT-BD intervention versus an active control (light exercise). We assessed depressive symptoms (primary outcome), verbal fluency (secondary outcome), and functioning/quality of life (exploratory outcomes) at baseline and 12-weeks. Results : No statistically significant differences were observed between groups for all outcomes (all p's>0.05). However, non-significant decreases in depressive symptoms were found in the subgroup of participants with baseline MADRS scores ≥10 in the QT-BD intervention only (p=0.07). Limitations : Our sample size was limited and the virtually-delivered format may have limited the positive benefits of face-to-face interventions. Conclusions : This novel pilot study suggests that QT-BD may be a feasible and efficacious intervention for reducing depressive symptoms in middle- and older-aged BD, particularly when baseline MADRS is ≥10, warranting further investigation in larger-scale trials.
RESUMEN
Digital surveys, such as mobile phone ecological momentary assessment (EMA), bear the potential to assess and target individual wellbeing in a personalized, real-time approach and allow for interaction in situations when in-person contact is not possible, such as during the coronavirus pandemic. While the use of digital technology might especially benefit research in older adults who find themselves in circumstances of reduced mobility, little is known about their barriers to adherence. We investigated baseline and structural factors that predict study withdrawal and adherence from daily smartphone EMA self-report surveys in the StayWELL Study. The StayWELL study is a longitudinal, observational study on the relationship between social restrictions during the coronavirus pandemic and mental well-being in 95 community-dwelling older aged adults (67-87 years) who were participants in a randomized clinical trial using EMA. Withdrawal was associated with less research staff changes and less likely in participants that reached the study mid-point. No baseline characteristics predicted withdrawal. Main reasons for withdrawal were communication issues, i.e. staff not being able to contact participants. We found an adherence rate of 82% and no fatigue effects. Adherence was predicted by education status, study participation duration, reaching the study midpoint and time between study start and enrollment. COVID infections or supporting people in the household was not related to adherence. To conclude, it is feasible to conduct an EMA study in older people without impacting engagement during a pandemic. Furthermore, personal characteristics and smartphone operating system (Android vs. iOS) used did not relate to engagement, allowing for a broad distribution of digital health technologies. Our study adds information on single predictive variables relevant for adherence and withdrawal from EMA smartphone surveys in older people that can inform the design of future digital EMA research to maximize engagement and reliability of study results.
