The RB-DSME shows feasibility and promise for enhancing health; a full-scale randomized trial is warranted.

Study Objectives Polysomnography (PSG) is considered the “gold standard” for assessing sleep, but cost and burden limit its use. Although wrist actigraphy and self-report diaries are feasible alternatives to PSG, few studies have compared all three modalities concurrently across multiple nights in the home to assess their relative validity across multiple sleep outcomes. This study compared sleep duration and continuity measured by PSG, actigraphy, and sleep diaries and examined moderation by race/ethnicity. Methods Participants from the Study of Women’s Health Across the Nation Sleep Study included 323 White (n = 147), African American (n = 120), and Chinese (n = 56) middle-aged community-dwelling women (mean age: 51 years, range: 48–57). PSG, wrist actigraphy (AW-64; Philips Respironics, McMurray, USA), and sleep diaries were collected concurrently in participants’ homes over three consecutive nights. Multivariable repeated-measures linear models compared time in bed (TIB), total sleep time (TST), sleep efficiency (SE), sleep latency (SL), and wake after sleep onset (WASO) across modalities. Results Actigraphy and PSG produced similar estimates of sleep duration and efficiency. Diaries yielded higher estimates of TIB, TST, and SE vs. PSG and actigraphy, and lower estimates of SL and WASO vs. PSG. Diary SL was shorter than PSG SL only among White women, and diary WASO was lower than PSG and actigraphy WASO among African American vs. White women. Conclusions Given concordance with PSG, Actigraphy may be preferred as an alternative to PSG for measuring sleep in the home. Future research should consider racial/ethnic differences in diary-reported sleep continuity.

Purpose The purpose of this qualitative, focus group study was to further refine the Resilience-based Diabetes Self-management Education (RB-DSME) recruitment process and intervention, build greater trust in the community, and identify strategies to enhance its sustainability as a community-based intervention in African American church settings. Methods Six 2-hour focus groups (N = 55; 10 men and 45 women) were led by a trained moderator with a written guide to facilitate discussion. Two sessions were conducted with individuals diagnosed with type 2 diabetes mellitus (T2DM) who participated in previous RB-DSME pilot interventions and their family members, two sessions with local church leaders, and two sessions with community healthcare providers who care for patients with T2DM. Two independent reviewers performed content analysis to identify major themes using a grounded theory approach. The validity of core themes was enhanced by external review and subsequent discussions with two qualitative methods consultants. Results There was expressed interest and acceptability of the RB-DSME program. Church connection and pastor support were noted as key factors in building trust and enhancing recruitment, retention, and sustainability of the program. Core themes across all groups included the value of incentives, the need for foundational knowledge shared with genuine concern, teaching with visuals, dealing with denial, balancing the reality of adverse consequences with hope, the importance of social support, and addressing healthcare delivery barriers. Conclusion Focus groups documented the feasibility and potential effectiveness of RB-DSME interventions to enhance diabetes care in the African American community. In clinical practice, inclusion of these core themes may enhance T2DM self-care and treatment outcomes.

Further support for the utility and generalizability of the positivity ratio was provided. Cultivating positive emotions may improve the health of individuals with type 2 diabetes.
