Treatment beliefs and preferences for psychological therapies for weight management

Acceptance and Commitment Therapy and Weight-Related Difficulties in Overweight and Obese Adults: A Systematic Review

Multiple studies have investigated the efficacy of acceptance and commitment therapy (ACT) in improving psychological flexibility among overweight and obese individuals. However, to date, no specific reviews have focused on ACT and weight-related difficulties in this population. This systematic review of the literature aims to identify and assemble all ACT interventions in randomized controlled trials (RCT) that address weight-related difficulties in the treatment of overweight and obese adults. The PRISMA 2020 framework was used for the systematic review, includes manual and computerized database searches. Five databases (Medline, PubMed, Scopus, PsycInfo, and Google) were utilized to gather all articles that: (a) published in English; (b) adopted the RCT design; (c) used ACT as an intervention; (d) included adult participants aged over 18 years with BMI of over 25 kg/m2, and (e) included weight-related difficulties and weight as outcome measures. The review identified seven studies comprising 698 overweight or obese participants of both genders. Improvements were reported in weight-related difficulties and percentage of weight loss in the ACT group and the non-ACT group. The present review supports ACT as an effective intervention that can help adults with weight-related difficulties and excess body weight. Further studies should be conducted in various overweight or obese populations with a more systematic RCT research design to establish the effectiveness of ACT in this area.

Investigating Determinants of Client Psychotherapy Preference: An Analog Study

Increased emphasis has been placed on elucidating the contribution of client variables, such as treatment preference, to optimize evidence-based practice. This analog study sought to better understand variables associated with treatment preference using a convenience sample of college students (n = 54) who read brief descriptions of three interventions for negative thoughts-defusion, noticing, and restructuring. They rated each on acceptability and practicality and completed measures of cognitive fusion, emotional distress, and experiential avoidance as possible moderating variables. Restructuring was overwhelmingly preferred and rated as more acceptable than the two alternatives by both the overall sample and a distressed subsample. Preference for defusion or noticing was not predicted by ratings of acceptability or practicality but by elevated levels of cognitive fusion and emotional distress consistent with a compensation model. Limitations of the study and its implications for further research on psychotherapy preference and its integration within evidence-based practice are discussed.

Comparing the effectiveness of emotion-focused and cognitive-behavioral therapies on body image, anxiety, and depression in women with PCOS

BACKGROUND

Polycystic ovary syndrome (PCOS) is a heterogeneous disease that is usually seen in women of reproductive age and causes complications such as body image dissatisfaction, anxiety, and depression. This study was done with the aim of comparing the effectiveness of emotion-focused therapy (EFT) and cognitive-behavioral therapy (CBT) on body image, anxiety, and depression in women with PCOS.

MATERIALS AND METHODS

This research was semi-experimental with a pre-test-post-test design with control and follow-up groups. The statistical population included all women with PCOS who were referred to the infertility clinic of Afzalipur Hospital in Kerman in 2022. A total of 45 patients were selected as a sample using the convenience sampling method and then they were randomly assigned to two experimental groups (15 people each) and a control group (15 people). After the pre-test, the experimental groups were subjected to the interventions of EFT and CBT, and afterward the post-test was performed. Cash et al., body image questionnaire, and Beck anxiety and depression questionnaires were used. Data were analyzed using PSS21 software and analysis of variance.

RESULTS

The findings revealed that the effectiveness of EFT and CBT on body image, anxiety, and depression is significant (P < 0.05). The comparison of the two therapy showed that the effect of CBT on body image, anxiety, and depression is more than EFT. Moreover, there was no statistically significant difference between the post-test and follow-up scores (P > 0.05).

CONCLUSION

According to the results, CBT can reduce dissatisfaction with body image, anxiety, and depression in women with PCOS, therefore it is recommended to use this therapy.

Cognitive behavioral therapy for lifestyle changes in patients with obesity and type 2 diabetes: a systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to examine the contribution of cognitive behavioral therapy (CBT) to the implementation of lifestyle changes, considering health-related and behavioral outcomes. A systematic literature review was performed using multiple databases (PsycInfo, PubMed and MEDLINE). The inclusion criteria comprised randomised controlled trials of CBT for lifestyle changes in patients with obesity and/or type 2 diabetes. The quality of study reporting was assessed with the revised Cochrane Collaboration's risk of bias tool. A meta-analysis was conducted on studies with appropriate outcomes. Nine randomised controlled trials, with a total sample size of 902 participants, met the inclusion criteria. The meta-analysis has shown a medium, significant effect size of CBT interventions for weight loss and weight maintenance, and a low, non-significant effect size of CBT interventions for reducing glycated hemoglobin (HbA1c) levels. A separate, combined, meta-analysis for all nine calculated effect sizes has yielded a medium and significant overall effect size for the model. Our review of the studies about the effectiveness of CBT in implementing lifestyle changes has, in comparison to usual control groups, proven the efficacy of CBT interventions in implementing lifestyle changes, especially for weight loss and weight maintenance.

Digital communication and virtual reality for extending the behavioural treatment of obesity - the patients' perspective: results of an online survey in Germany

BACKGROUND

CBT has been found effective for the treatment of EDs and obesity. However not all patients achieve clinically significant weight loss and weight regain is common. In this context, technology-based interventions can be used to enhance traditional CBT but are not yet widespread. This survey therefore explores the status quo of pathways of communication between patients and therapists, the use of digital applications for therapy as well as attitudes towards VR from the perspective of patients with obesity in Germany.

METHODS

This cross-sectional online survey was conducted in October 2020. Participants were recruited digitally through social media, obesity associations and self-help groups. The standardized questionnaire included items concerning current treatment, paths of communication with their therapists, and attitudes toward VR. The descriptive analyses were performed with Stata.

RESULTS

The 152 participants were mostly female (90%), had a mean age of 46.5 years (SD = 9.2) and an average BMI of 43.0 kg/m² (SD = 8.4). Face-to-face communication with their therapist was considered of high importance in current treatment (M = 4.30; SD = 0.86) and messenger apps were the most frequently used digital application for communication. Participants were mostly neutral regarding the inclusion of VR methods in obesity treatment (M = 3.27; SD = 1.19). Only one participant had already used VR glasses as part of treatment. Participants considered VR suitable for exercises promoting body image change (M = 3.40; SD = 1.02).

DISCUSSION

Technological approaches in obesity therapy are not widespread. Face-to-face communication remains the most important setting for treatment. Participants had low familiarity with VR but a neutral to positive attitude toward the technology. Further studies are needed to provide a clearer picture of potential treatment barriers or educational needs and to facilitate the transfer of developed VR systems into clinical practice.

Changes in eating behavior through lifestyle treatment in women with polycystic ovary syndrome (PCOS): a randomized controlled trial

BACKGROUND

Eating behaviors like emotional eating, external eating and restrained eating play an important role in weight gain and weight loss in the general population. Improvements in eating behavior are important for long-term weight. This has not yet been studied in women with Polycystic Ovary Syndrome (PCOS). The aim of this study is to examine if a three-component lifestyle intervention (LI) is effective for improving disordered eating behavior in women with PCOS.

METHODS

Women diagnosed with PCOS (N = 183), with a body mass index (BMI) > 25 kg/m² and trying to achieve a pregnancy were either assigned to 1 year of 20 group sessions of cognitive behavioral therapy (CBT) combined with nutritional advice and exercise with or without additional feedback through Short Message Service (SMS) or Care As Usual (CAU), which includes the advice to lose weight using publicly available services.

RESULTS

The Eating Disorder Examination Questionnaire (EDEQ) scores worsened in CAU (47.5%) and improved in the LI (4.2%) at 12 months. The difference between the LI and CAU was significant (P = 0.007) and resulted in a medium to large effect size (Cohen's d: - 0.72). No significant differences were observed in EDEQ scores between LI with SMS compared to LI without SMS (Cohen's d: 0.28; P = 0.399). Also, weight loss did not mediate the changes in eating behavior. An overall completion rate of 67/183 (36.6%) was observed.

CONCLUSIONS

A three-component CBT lifestyle program resulted in significant improvements in disordered eating behavior compared to CAU. Changes in disordered eating behavior are important for long-term weight loss and mental health.

The effectiveness of acceptance and commitment therapy upon weight management and psychological well-being of adults with overweight or obesity: A systematic review

Several studies have examined acceptance and commitment therapy's (ACT) effectiveness for addressing physical and psychological distress people with obesity can face. Nevertheless, no review focusing specifically on ACT analysing randomized controlled trials (RCT) has been done up to date in this field. The present systematic review was developed following the PRISMA statement and aimed to examine ACT's effects on weight management and psychological well-being of adults with overweight or obesity. A conjunction of keywords related to ACT and excess weight was searched in four databases (Medline, PubMed, Psycinfo and Scopus) for articles meeting inclusion criteria. The literature search yielded 2,074 papers, and 16 were included in the review, finally. In 71.43% of the studies, ACT was effective to enhance psychological well-being; in 50% effectively targeted process variables and health behaviours related to weight management; in 31.82% of studies, physical variables were improved; and 21.38% of studies showed evidence in favour of ACT for eating behaviour modification. The present review supports ACT for promoting emotional aspects of individuals immersed in such weight-related battles and highlights the benefits of psychological well-being-oriented ACT in the context of obesity treatment. More studies targeting psychological well-being primarily and with longer follow-ups are required.

The Effectiveness of an Acceptance and Commitment Therapy and Mindfulness Group Intervention for Enhancing the Psychological and Physical Well-Being of Adults with Overweight or Obesity Seeking Treatment: The Mind&Life Randomized Control Trial Study Protocol

Although several interventions that target obesity have been examined, the success of these interventions in generating and maintaining positive results has yet to be confirmed. This study protocol therefore presents a trial aimed at analyzing the effectiveness of a well-being-centered acceptance and commitment therapy (ACT)- and mindfulness-based group intervention following the valued-based healthy living (VHL) approach (Mind&Life intervention) for individuals experiencing overweight-related distress. A randomized controlled trial with two parallel groups will be conducted in 110 adults attending primary care units with overweight or obesity. Participants will be randomly allocated to one of the two study conditions. Interventions will either be the treatment as usual (TAU) or the Mind&Life intervention—an ACT- and mindfulness-based intervention—plus the TAU intervention. Quality of life, weight self-stigma, general health status, eating habits, physical activity, eating behavior, anthropometric, body composition, cardiovascular, and physiological variables, as well as process variables, will be examined at baseline, posttreatment, 6-month follow-up, and 1-year follow-up. This trial aims to offer a novel psychological approach for addressing the psychological and physical impairments suffered by people with overweight or obesity in the current environment. ClinicalTrials.gov identifier: NCT03718728.

Cognitive Behavioral Approach to Treat Obesity: A Randomized Clinical Trial

Our aim was to analyze and compare the effects of three different long-term treatments on anthropometric profiles, eating behaviors, anxiety and depression levels, and quality of life of groups of adults with obesity. Methods: The 43 participants in the study were randomly assigned to one of three groups: the education and health group (EH, n = 12), which received lectures on health topics; the physical exercise group (PE, n = 13), which underwent physical training; and the interdisciplinary therapy plus cognitive behavioral therapy (IT + CBT) (n = 18) group, which received physical training, nutritional advice, and physical and psychological therapy. Results: Total quality of life increased significantly in the EH group (△ = 2.00); in the PE group, body weight significantly decreased (△ = -1.42) and the physical domain of quality of life improved (△ = 1.05). However, the most significant changes were seen in the IT + CBT group, in which the anthropometric profile improved; there were an increase in quality of life in all domains (physical, psychological, social, and environmental), an improvement in eating behaviors [Dutch Eating Behavior Questionnaire (DEBQ), total △ = -8.39], and a reduction in depression [Beck Depression Inventory (BDI), △ = -10.13). Conclusion: The IT + CBT program was more effective than the PE and EH programs. Clinical Trial Registration Number: NCT02573688.

Cognitive behavioral therapy to aid weight loss in obese patients: current perspectives

Obesity is a chronic condition associated with risk factors for many medical complications and comorbidities such as cardiovascular diseases, some types of cancer, osteoarthritis, hypertension, dyslipidemia, hypercholesterolemia, type-2 diabetes, obstructive sleep apnea syndrome, and different psychosocial issues and psychopathological disorders. Obesity is a highly complex, multifactorial disease: genetic, biological, psychological, behavioral, familial, social, cultural, and environmental factors can influence in different ways. Evidence-based strategies to improve weight loss, maintain a healthy weight, and reduce related comorbidities typically integrate different interventions: dietetic, nutritional, physical, behavioral, psychological, and if necessary, pharmacological and surgical ones. Such treatments are implemented in a multidisciplinary context with a clinical team composed of endocrinologists, nutritionists, dietitians, physiotherapists, psychiatrists, psychologists, and sometimes surgeons. Cognitive behavioral therapy (CBT) is traditionally recognized as the best established treatment for binge eating disorder and the most preferred intervention for obesity, and could be considered as the first-line treatment among psychological approaches, especially in a long-term perspective; however, it does not necessarily produce a successful weight loss. Traditional CBT for weight loss and other protocols, such as enhanced CBT, enhanced focused CBT, behavioral weight loss treatment, therapeutic education, acceptance and commitment therapy, and sequential binge, are discussed in this review. The issue of long-term weight management of obesity, the real challenge in outpatient settings and in lifestyle modification, is discussed taking into account the possible contribution of mHealth and the stepped-care approach in health care.

European Guidelines for Obesity Management in Adults

Obesity is a chronic metabolic disease characterised by an increase of body fat stores. It is a gateway to ill health, and it has become one of the leading causes of disability and death, affecting not only adults but also children and adolescents worldwide. In clinical practice, the body fatness is estimated by BMI, and the accumulation of intra-abdominal fat (marker for higher metabolic and cardiovascular disease risk) can be assessed by waist circumference. Complex interactions between biological, behavioural, social and environmental factors are involved in regulation of energy balance and fat stores. A comprehensive history, physical examination and laboratory assessment relevant to the patient's obesity should be obtained. Appropriate goals of weight management emphasise realistic weight loss to achieve a reduction in health risks and should include promotion of weight loss, maintenance and prevention of weight regain. Management of co-morbidities and improving quality of life of obese patients are also included in treatment aims. Balanced hypocaloric diets result in clinically meaningful weight loss regardless of which macronutrients they emphasise. Aerobic training is the optimal mode of exercise for reducing fat mass while a programme including resistance training is needed for increasing lean mass in middle-aged and overweight/obese individuals. Cognitive behavioural therapy directly addresses behaviours that require change for successful weight loss and weight loss maintenance. Pharmacotherapy can help patients to maintain compliance and ameliorate obesity-related health risks. Surgery is the most effective treatment for morbid obesity in terms of long-term weight loss. A comprehensive obesity management can only be accomplished by a multidisciplinary obesity management team. We conclude that physicians have a responsibility to recognise obesity as a disease and help obese patients with appropriate prevention and treatment. Treatment should be based on good clinical care, and evidence-based interventions; should focus on realistic goals and lifelong multidisciplinary management.
