0833 Acceptability of the Transdiagnostic Behavioral Sleep and Circadian Intervention to Individuals in Cardiac Rehabilitation

Abstract

Introduction Sleep health is often compromised among individuals undergoing cardiac rehabilitation and does not consistently improve over the course of treatment. Behavioral sleep and circadian interventions may improve the sleep health of cardiac rehabilitation patients but have not been widely tested in this context. We conducted a preliminary test of an adapted version of the Transdiagnostic Sleep and Circadian Intervention (TranS-C) with Veterans in cardiac rehabilitation to evaluate its acceptability with these unique patients. Methods Eight Veterans with sleep disturbance and/or sleep-related impairment who were participating in outpatient cardiac rehabilitation completed the adapted TranS-C intervention and post-intervention acceptability measures. Intervention acceptability was assessed quantitatively with subscales from the Multidimensional Treatment Satisfaction Measure (subscale scores range from 0-4; higher scores indicate greater satisfaction) and qualitatively via semi-structured interviews. We calculated descriptive statistics for quantitative measures and analyzed semi-structured interviews using a rapid qualitative analysis approach. Results Participants felt the intervention was suitable to their needs (M=3.00, SD=.94) and useful for increasing their knowledge and understanding of sleep problems and how to manage them (M=3.50, SD=.69). Participants endorsed positive attitudes toward the intervention (M=3.63, SD=.58) and high likelihood of recommending the intervention to others similarly experiencing sleep problems (M=3.63, SD =.58). Following the intervention, 62.5% of participants indicated that their sleep disturbance and sleep-impairment were ‘much better’ than at the first study visit and 37.5% indicated their sleep disturbance and sleep-related impairment were ‘somewhat better’. Qualitative findings converged with the noted quantitative findings. Conclusion Veteran cardiac rehabilitation patients expressed satisfaction and positive attitudes toward the adapted TranS-C intervention. All participants reported subjective post-intervention improvements in sleep disturbance and sleep-related impairment. These findings provide preliminary support for further large-scale testing of adapted TranS-C in cardiac rehabilitation.
