RESUMEN

Dietary lapses (i.e., instances of dietary non-adherence) are common during weight loss attempts, and compromise success in two ways: increasing caloric intake and demoralizing the participant, sometimes leading them to abandon their weight control goals altogether. Efforts to understand and prevent demoralization have received almost no research attention. Self-compassion has high potential to promote adaptive responses to these setbacks because it reframes "failure" and promotes self-improvement. Past research shows that when participants experience a lapse, those practicing higher self-compassion report higher self-efficacy and intentions to continue dieting. The current study extended this literature to examine whether self-compassion in response to a lapse would predict lower likelihood of a subsequent same-day lapse and greater reports of perceived control over weight management behaviors. We also examined whether the individual facets of self-compassion, including self-kindness (treating oneself the way one would a friend); common humanity (the understanding that everyone has struggles); and mindfulness (non-judgmental awareness of thoughts and feelings) are associated with these outcomes. Participants (N = 140) enrolled in a behavioral weight loss trial completed 6 ecological momentary assessment (EMA) surveys a day for seven days. Total self-compassion and each facet of self-compassion individually were all associated with less negative affect after a lapse. None of the self-compassion variables predicted the likelihood of participants reporting a lapse again that day. However, higher total self-compassion and higher self-kindness after a lapse were both associated with greater perceived self-control over weight management behaviors in the hours following. Common humanity and mindfulness, respectively, were not associated with reports of perceived control. Results suggest that self-compassion following dieting setbacks may prevent goal disengagement, and that self-kindness is the facet most strongly associated with adaptive responses to these setbacks.

RESUMEN

BACKGROUND: Mindful awareness, willingness and values clarity have been examined as protective factors across a wide range of problems, including overweight/obesity. However, these variables have almost exclusively been examined at the trait-level. It is possible that these variables also fluctuate within individuals in daily life, and that these intraindividual fluctuations may in turn be related to food craving and dietary lapse. The current study used ecological momentary assessment (EMA) to examine the extent to which momentary mindful awareness, willingness, and values clarity varied within-person, and were associated with craving and likelihood of dietary lapse among weight-loss seeking individuals with overweight/obesity prior to starting a weight loss program. We also examined the extent to which craving was associated with dietary lapse. METHODS: Adults with overweight/obesity (N = 126) completed one week of EMA prior to enrolling in a randomized controlled trial of behavioral weight loss treatments. They responded to EMA questions assessing dietary lapses, craving, mindful awareness, willingness, and values clarity six-times per day. RESULTS: Mindful awareness, willingness, and values clarity demonstrated substantial within-person variability, and higher within-person mindful awareness, willingness, and values clarity were concurrently (but not prospectively) associated with lower craving and likelihood of dietary lapse. Higher craving was concurrently (but not prospectively) associated with higher likelihood of dietary lapse. Between-person, higher mindful awareness, willingness, and values clarity were associated with lower craving and likelihood of dietary lapse, and higher craving was associated with greater frequency of dietary lapses. CONCLUSION: Mindful awareness, willingness, and values clarity vary substantially at the daily level, and may be important mechanisms to target to reduce craving and dietary lapses in the daily lives of individuals with overweight/obesity.

RESUMEN

Behavioral weight loss treatment (BT) for individuals with overweight and obesity is effective but leaves room for improvement. Mindfulness and acceptance-based treatments may bolster weight loss outcomes; yet, little is known about the efficacy of the individual components or the combinations of components that are most effective in producing weight loss above and beyond standard BT strategies for weight loss. This protocol manuscript describes the use of a multiphase optimization strategy to evaluate the independent and combinatory efficacy of three mindfulness and acceptance-based components (mindful awareness, willingness, values). Using a 2 × 2 × 2 factorial design, participants (N = 288) will be randomized to one of eight conditions, each representing a combination of core MABT strategies in addition to foundational BT strategies. Assessments occur at baseline, mid-treatment (week 24 through 26), post-treatment, and at 6, 12, and 24-month follow-up. The primary aim is to elucidate the independent efficacy of each MABT component on weight loss above gold-standard BT. The secondary aims are to evaluate the independent effect of these components on calorie intake, physical activity, and overall quality of life; evaluate target engagement (i.e., the degree to which each treatment component affects proposed mechanisms of action); and evaluate the potential moderating effect of susceptibility to internal and external food cues on outcomes. The exploratory aim is to quantify any component interaction effects (which may be synergistic, fully additive, or partially additive).

RESUMEN

Outcomes from cognitive behavioral therapy for binge-eating spectrum disorders are suboptimal, possibly due in part to deficits in self-regulation (i.e., the ability to control behavior in pursuit of long-term goals despite internal challenges). Mindfulness and acceptance-based treatments (MABTs) integrate behavioral treatment with psychological strategies designed to enhance self-regulation, yet little is known about how and for whom they are effective. The present study will utilize the multiphase optimization strategy to identify which of four MABT components (mindful awareness, distress tolerance, emotion modulation, values-based decision making) to include in a fully powered clinical trial. Participants (n = 256) will be randomized to 16 sessions in one of 16 conditions, each a different combination of MABT components being included or excluded from a base behavioral treatment. Our primary aim is to evaluate each component's independent efficacy on disordered eating symptoms. Our secondary aims are to confirm each component's target engagement (i.e., whether each component improves the targeted variable and outcomes), and test that each component's efficacy is moderated by baseline weaknesses in the same component (e.g., that participants with poor distress tolerance at baseline benefit most from the distress tolerance component). Our exploratory aim is to quantify the component interaction effects.

RESUMEN

OBJECTIVE: Obesity is largely attributable to excess caloric intake, in particular from "junk" foods, including salty snack foods. Evidence suggests that neurobiological preferences to consume highly hedonic foods translate (via implicit processes) into poor eating choices, unless overturned by inhibitory mechanisms or interrupted by explicit processes. The primary aim of the current study was to test the independent and combinatory effects of a computerized inhibitory control training (ICT) and a mindful decision-making training (MDT) designed to facilitate de-automatization. METHODS: We randomized 119 habitual salty snack food eaters to one of four short, training conditions: MDT, ICT, both MDT and ICT, or neither (i.e., psychoeducation). For 7 days prior to the intervention and 7 days following the intervention, participants reported on their salty snack food consumption 2 times per day, on 3 portions of their days, using a smartphone-based ecological momentary assessment system. Susceptibility to emotional eating cues was measured at baseline. RESULTS: Results indicated that the effect of MDT was consistent across levels of trait emotional eating, whereas the benefit of ICT was apparent only at lower levels of emotional eating. No synergistic effect of MDT and ICT was detected. CONCLUSIONS: These results provide qualified support for the efficacy of both types of training for decreasing hedonically-motivated eating. Moderation effects suggest that those who eat snack foods for reasons unconnected to affective experiences (i.e., lower in emotional eating) may derive benefit from a combination of ICT and MDT. Future research should investigate the additive benefit of de-automization training to standard weight loss interventions.

RESUMEN

BACKGROUND: Tens of thousands of bariatric surgery patients each year experience sub-optimal weight loss, significant regain, or both. Weight regain can contribute to a worsening of weight-related co-morbidities, and for some, leads to secondary surgical procedures. Poor weight outcomes have been associated with decreased compliance to the recommended postoperative diet. Decreased compliance may be partially due to a lack of psychological skills necessary to engage in healthy eating behaviors over the long term, especially as the effects of surgery (on appetite, hunger, and desire for food) decrease. Many behavioral interventions do not sufficiently address these challenges and often have limited effectiveness. The study aimed to evaluate the feasibility, acceptability, and preliminary effectiveness of a novel 10-week acceptance-based behavioral intervention to stop postoperative weight regain. METHODS: A sample of bariatric surgery patients (n = 11) who regained at least 10 % of their maximum lost postoperative weight was recruited. All participants received the intervention, which emphasized psychological skills thought to be integral to successful weight control post-surgery. RESULTS: The intervention was shown to be feasible and acceptable, with 72 % retention and high mean rating (4.25 out of 5.00) of program satisfaction among completers. Weight regain was stopped, and even reversed, with a mean total body weight loss of 3.58 ± 3.02 % throughout the 10-week intervention. There were also significant improvements in eating-related and acceptance-related variables. CONCLUSIONS: These findings provide initial support for the use of a psychological acceptance-based intervention for weight regain in bariatric surgery patients.

RESUMEN

BACKGROUND: Physical activity (PA) is essential for health, but many adults find PA adherence challenging. Acceptance of discomfort related to PA may influence an individual's ability to begin and sustain a program of exercise. The aim of this study was to evaluate the psychometric properties of the Physical Activity Acceptance Questionnaire (PAAQ). METHODS: The PAAQ was administered to 3 distinct samples (N = 418). Each sample completed additional self-report measures; 1 sample also wore accelerometers for 7 days (at baseline and 6 months later). RESULTS: The PAAQ demonstrated high internal validity for its total score (α = .89) and 2 subscales (Cognitive Acceptance α = .86, Behavioral Commitment α = .85). The PAAQ also showed convergent validity with measures of mindfulness, self-reported physical activity levels, and accelerometer-verified levels of moderate-to-vigorous PA (MVPA; P-values < .05). The Cognitive Acceptance subscale showed predictive validity for objectively-verified PA levels among individuals attempting to increase PA over 6 months (P = .05). Test-retest reliability for a subset of participants (n = 46) demonstrated high consistency over 1 week (P < .0001). CONCLUSIONS: The PAAQ demonstrates sound psychometric properties, and shows promise for improving the current understanding of PA facilitators and barriers among adults.

RESUMEN

OBJECTIVE: Mindfulness and its related constructs (e.g., awareness and acceptance) are increasingly being recognized as relevant to understanding eating disorders and improving treatment. The purpose of this study was to (1) examine the relationship between mindfulness and ED symptomatology at baseline and (2) examine how changes in mindfulness relate to change in ED symptomatology. METHOD: Measures of mindfulness and ED symptomatology were administered to 88 patients upon admission to residential ED treatment and at discharge. RESULTS: Baseline ED symptomatology was associated with lower awareness, acceptance, and cognitive defusion, and higher emotional avoidance. Improvements in these variables were related to improvement in ED symptomatology. DISCUSSION: Interventions targeting mindfulness could be beneficial for patients with EDs.

RESUMEN

This study compared two theoretically opposed strategies for acute pain management: an acceptance-based and a change-based approach. These two strategies were compared in a within-subjects design using the cold pressor test as an acute pain induction method. Participants completed a baseline pain tolerance assessment followed by one of the two interventions and another pain tolerance test. The alternate strategy was presented in a separate, but otherwise identical, experimental session. On average, both interventions significantly increased pain tolerance relative to baseline, with no significant difference between the two intervention conditions. Baseline psychological acceptance emerged as a significant moderator of intervention efficacy; individuals with a high level of acceptance benefited significantly more from the acceptance intervention, whereas those with a low level of acceptance benefited more from the change-based intervention. Implications for increasing the effectiveness of psychotherapeutic treatments based on individual differences are discussed.

RESUMEN

Approximately 90% of cardiac events are attributable to a small number of modifiable behavioral risk factors that, if changed, can greatly decrease morbidity and mortality. However, few at-risk individuals make recommended behavioral changes, including those who receive formal interventions designed to facilitate healthy behavior. Given evidence for the potential of specific psychological factors inherent in acceptance-based behavior therapy (ABBT; that is, intolerance of discomfort, mindfulness, and values clarity) to impact health behavior change, the authors evaluated the feasibility and initial effectiveness of an ABBT pilot program designed to increase adherence to behavioral recommendations among cardiac patients. Participants (N = 16) were enrolled in four, 90-min group sessions focused on developing mindfulness and distress tolerance skills, and strengthening commitment to health-related behavior change. Participants reported high treatment satisfaction and comprehension and made positive changes in diet and physical activity. This was the first evaluation of an ABBT program aimed at increasing heart-healthy behaviors among cardiac patients.

RESUMEN

The purpose of this project was to develop a bidimensional measure of mindfulness to assess its two key components: present-moment awareness and acceptance. The development and psychometric validation of the Philadelphia Mindfulness Scale is described, and data are reported from expert raters, two nonclinical samples (n = 204 and 559), and three clinical samples including mixed psychiatric outpatients (n = 52), eating disorder inpatients (n = 30), and student counseling center outpatients (n = 78). Exploratory and confirmatory factor analyses support a two-factor solution, corresponding to the two constituent components of the construct. Good internal consistency was demonstrated, and relationships with other constructs were largely as expected. As predicted, significant differences were found between the nonclinical and clinical samples in levels of awareness and acceptance. The awareness and acceptance subscales were not correlated, suggesting that these two constructs can be examined independently. Potential theoretical and applied uses of the measure are discussed.
