Description
This body of research sought to explore relationships between cognitive function and physical activity (PA), sedentary behavior (SB), and sleep, independently and in conjunction, in mid-life to older adults with no known cognitive impairment. Aging is associated with cognitive decline, and lifestyle behaviors such as PA, SB, and sleep, may mitigate this decline. First, a systematic review and meta-analysis was conducted to examine the effect of aerobic PA interventions on memory and executive function in sedentary adults. Second, a longitudinal study was conducted to examine the association between SB and odds of incident cognitive impairment, and SB and cognitive decline in older adults. Last, a cross-sectional study was conducted to examine the joint associations between different levels of sleep with levels of PA, and sleep with levels of sedentary time on memory and executive function. This body of research provided evidence to support the association between aerobic PA and improved cognitive function, SB and incident cognitive impairment and cognitive function declines, and the joint association of sleep and different levels of PA and ST on cognitive function by hypertension status.

Description
Research on acceptability of mindfulness-based interventions (MBIs) for populations with substance use disorders (SUD) is extremely limited. Intervention development and testing guidelines note that acceptability of the intervention by the target population is important for retention, efficacy, and intervention integrity. Yet, MBIs for SUD studies have not measured acceptability or have done so in a cursory manner, therefore, the question remains of whether MBIs are acceptable to populations in SUD treatment. The proposed study seeks to fill this knowledge gap by undertaking a conceptually-grounded empirical approach to assess acceptability of Moment-by-Moment in Women’s Recovery (MMWR), which is an MBI for women with SUD. This document is divided into five chapters. Chapter 1 introduces the topic and provides background literature. Chapter 2 systematically reviews MBIs for SUD studies to assess measurement of acceptability. Chapter 3 analyzes the psychometric properties of two acceptability surveys used in MMWR. Chapter 4 examines the associations among the acceptability surveys, personal characteristics of the participants, and application of intervention techniques. And Chapter 5 summarizes the previous chapters and discusses future directions for this line of work. There is a need for a greater understanding of which factors may influence participants’ abilities to accept an intervention. The results identify sociodemographic and clinical characteristics that can inform future intervention adaptations, screening, or pre-intervention programs to increase efficiency of SUD intervention delivery and relevance. The long-term goal is to improve fit and efficacy of MBIs for SUD for minority and underrepresented populations.
