Pilot Trial of Acceptance-Based Behavioral Weight Loss and Neurocognition Among American Indians

Acceptance-based behavioral therapies (ABTs) for obesity may be superior to standard behavioral therapies but have not been adequately tested with American Indians (AIs). Neurocognitive function is also unexamined in relation to behavioral weight loss among AIs despite findings that neurocognition predicts outcomes in general samples, may help explain some of the benefits of ABTs, and may be relevant to marginalized groups. The primary objective of this pilot was to examine the feasibility/acceptability of ABT in an AI sample. Exploratory analyses examined the relationship between neurocognition and weight loss. Forty-eight AI adults with overweight/obesity (ages 43.3 ± 10.3 years, 85% female; baseline body mass index = 36.8 ± 4.4 kg/m2) enrolled in a 6-month open ABT weight loss trial. Feasibility indices, including screening/enrollment, session attendance, retention rates for posttreatment assessments, and program acceptability were examined. Percent weight loss (%WL) was assessed as well as fluid and crystalized neurocognition (National Institutes of Health Toolbox Cognition Battery [NIHTB-CB]). We enrolled 79% of the eligible sample and retained 75% (N = 36) at posttreatment assessments. Program completers lost an average of 5.2 ± 4.9% of initial body weight (dz = 1.14), whereas intent-to-treat analyses show a mean loss of 4.1 ± 4.7%. Participants reported high satisfaction, effectiveness, and cultural appropriateness. Exploratory analyses of neurocognitive domains suggested that crystalized cognition was higher among completers, and higher baseline cognitive flexibility predicted greater %WL (β = .34, p = .05). ABT resulted in clinically significant weight loss in an AI sample. A controlled trial of ABT in a larger, more diverse sample is warranted to determine whether (a) the findings are robust, generalizable, and/or superior to other treatments and (b) neurocognitive factors moderate outcomes.

Putting values into words: An examination of the text characteristics of values articulation

Acceptance-based behavioral therapies (ABBTs) are aimed at helping clients cultivate an accepting stance towards their internal experiences and encouraging values articulation and action. A sizeable experimental literature documents the specific utility of increasing acceptance (e.g., Eifert & Hefner, 2003; Levitt, Brown, Orsillo, & Barlow, 2004), but less is known about the values component of these therapies. The present exploratory study preliminarily investigated the linguistic text characteristics of values articulation narratives, the potential impact of individual difference variables on values writing text characteristics, and the relationship between text characteristics and anticipatory anxiety in preparation for a stressful laboratory challenge in a sample of 63 undergraduates. Values writing was characterized by expression of positive emotion and insight and both of these text characteristics were negatively associated with anticipatory anxiety. Both self-reported acceptance and high self-esteem were negatively associated with the expression of anxiety in values narratives. Treatment and research implications are discussed.

Mindfulness and Acceptance-Based Behavioral Therapies for Anxiety Disorders

This article presents a brief conceptual overview of acceptance-based behavioral therapies (ABBTs) for anxiety disorders, followed by a review and summary of the recent efficacy studies of ABBTs for anxiety and comorbid disorders. We discuss clinical implications, including the importance of targeting reactivity and experiential avoidance in interventions for anxiety disorders through the use of mindfulness and other acceptance-based strategies, as well the encouragement of engagement in meaningful activities or valued action. We also address future directions for research, such as expanding research to include more randomized control trials comparing ABBTs for specific anxiety disorders to other active treatments, examining mechanisms of change, exploring adaptations in different care-delivery contexts, as well as determining the applicability of these approaches to clients from marginalized or non-dominant statuses.

Clinical Considerations in Using Mindfulness- and Acceptance-Based Approaches With Diverse Populations: Addressing Challenges in Service Delivery in Diverse Community Settings

Mindfulness- and acceptance-based strategies effectively alter clients' relationships with their internal experiences, which may have been previously restricted, avoided, or even beyond clients' awareness. Even though the scientific exploration of the psychological benefits of mindfulness in the treatment literature continues to be in its infancy, it is important to uphold best practices by exploring the applications of these therapeutic approaches in diverse community populations. In this article, we discuss recommendations for addressing challenges that have arisen while delivering mindfulness- and acceptance-based behavioral therapies to consumers of mental health services from underserved and underrepresented backgrounds (e.g., marginalized racial, religious, and socioeconomic groups). Specific case examples illustrate the challenges of promoting acceptance in the face of adversity, the acceptability of mindfulness, attending to differences in the therapist and client perspectives, and promoting the pursuit of values in the face of adversity. Clinical recommendations and suggestions for dissemination of these approaches to clinicians working with racially and ethnically diverse, underserved populations are discussed.

The Effect of Values Affirmation on Psychological Stress

There is growing evidence for the efficacy of acceptance-based behavioral therapies, which aim to increase acceptance of internal experiences and values-consistent action. Further, experimental studies have demonstrated that acceptance decreases distress and increases willingness to engage in challenging tasks (e.g. Levitt, Brown, Orsillo, & Barlow, 2004). However, research demonstrating the positive effects of values articulation on psychological functioning is needed. The goal of the present study was to evaluate the efficacy of a brief intervention in reducing anxiety related to a stressful speech task. Contrary to predictions, engagement in values writing did not reduce anticipatory or posttask anxiety relative to engagement in a neutral writing task. However, self-esteem significantly predicted anxious response to the task. Experiential avoidance and valued living were also associated with anxious response to the task, although the contribution of these predictors was not statistically significant.
