Linardon J, Hindle A, Brennan L. Dropout from cognitive-behavioral therapy for eating disorders: A meta-analysis of randomized, controlled trials. Int J Eat Disord 2018; 51:381-391. [PMID: 29493805 DOI: 10.1002/eat.22850] [Citation(s) in RCA: 78] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2017] [Revised: 01/14/2018] [Accepted: 01/14/2018] [Indexed: 01/13/2023]
Abstract
OBJECTIVE Cognitive-behavioral therapy (CBT) is efficacious for a range of eating disorder presentations, yet premature dropout is one factor that might limit CBTs effectiveness. Improved understanding of dropout from CBT for eating disorders is important. This meta-analysis aimed to study dropout from CBT for eating disorders in randomized controlled trials (RCTs), by (a) identifying the types of dropout definitions applied, (b) providing estimates of dropout, (c) comparing dropout rates from CBT to non-CBT interventions for eating disorders, and (d) testing moderators of dropout. METHOD RCTs of CBT for eating disorders that reported rates of dropout were searched. Ninety-nine RCTs (131 CBT conditions) were included. RESULTS Dropout definitions varied widely across studies. The overall dropout estimate was 24% (95% CI = 22-27%). Diagnostic type, type of dropout definition, baseline symptom severity, study quality, and sample age did not moderate this estimate. Dropout was highest among studies that delivered internet-based CBT and was lowest in studies that delivered transdiagnostic enhanced CBT. There was some evidence that longer treatment protocols were associated with lower dropout. No significant differences in dropout rates were observed between CBT and non-CBT interventions for all eating disorder subtypes. CONCLUSION Present study dropout estimates are hampered by the use of disparate dropout definitions applied. This meta-analysis highlights the urgency for RCTs to utilize a standardized dropout definition and to report as much information on patient dropout as possible, so that strategies designed to minimize dropout can be developed, and factors predictive of CBT dropout can be more easily identified.

Int J Obes (Lond) 2018; 43:374-383. [PMID: 29686382 DOI: 10.1038/s41366-018-0067-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Revised: 02/09/2018] [Accepted: 02/13/2018] [Indexed: 11/09/2022]
Abstract
OBJECTIVES The objective of this study was to determine whether habit-based interventions are clinically beneficial in achieving long-term (12-month) weight loss maintenance and explore whether making new habits or breaking old habits is more effective. METHODS Volunteer community members aged 18-75 years who had overweight or obesity (BMI ≥ 25 kg/m2) were randomized in a single-blind, three-arm, randomized controlled trial. Ten Top Tips (TTT), Do Something Different (DSD), and the attention-only waitlist (WL) control groups were conducted for 12 weeks from July to October 2015. Participants were followed up post-intervention (all groups) and at 6 and 12-month post-intervention (Ten Top Tips and Do Something Different only). The primary outcome was weight-loss maintenance at 12-month follow-up. Secondary outcomes included weight loss at all time points, fruit and vegetable consumption, exercise, wellbeing, depression, anxiety, habit strength, and openness to change. RESULTS Of the 130 participants assessed for eligibility, 75 adults (mean BMI 34.5 kg/m2 [SD 6.2]), with a mean age of 51 years were recruited. Assessments were completed post-intervention by 66/75 (88%) of participants and by 43/50 (86%) at 12 months. At post-intervention, participants in the Ten Top Tips (-3.3 kg; 95% CI -5.2, -1.4) and Do Something Different (-2.9 kg; 95% CI -4.3, -1.4) interventions lost significantly more weight (P = < .001) than those on the waitlist control (-0.4 kg; 95% CI -1.2, 0.3). Both intervention groups continued to lose further weight to the 12-month follow-up; TTT lost an additional -2.4 kg (95% CI -5.1, 0.4) and DSD lost -1.7 kg (95% CI -3.4, -0.1). At 12-month post-intervention, 28/43 (65%) of participants in both intervention groups had reduced their total body weight by ≥5%, a clinically important change. CONCLUSIONS Habit-based weight-loss interventions-forming new habits (TTT) and breaking old habits (DSD), resulted in clinically important weight-loss maintenance at 12-month follow-up.

Expected benefits and motivation to weight loss in relation to treatment outcomes in group-based cognitive-behavior therapy of obesity. Eat Weight Disord 2018; 23:205-214.

Abstract
PURPOSE We aimed to determine cognitive drivers, expected to play a role in target reach and/or attrition in obesity programs. METHODS We recorded the expected benefits of weight loss, weight targets, primary motivation for weight loss, perceived treatment needs, readiness and self-confidence to be successful and a battery of psychopathology questionnaires in 793 subjects with obesity (68% women; mean age 48.7; 46% obesity class III) enrolled into a group-based cognitive-behavioral treatment program. Their relevance on attrition and successful weight loss outcome were tested by logistic regression analysis. RESULTS The expected benefits of weight loss scored very high in all physical, psychological and social areas, with differences between genders. Attrition rate was 24, 41 and 65% at 6-, 12-, and 24-month follow-up. Average weight loss was 5.8 ± 7.1 kg (- 4.8%) at 6 months, with 17% of cases (32% of continuers) maintaining weight loss > 10% at 24 months. After adjustment for confounders, attrition was reduced by concern for present health, motivation/consciousness of the importance of physical activity and need for support; treatment discontinuation was favored by concern for body image, by expectations for drug treatment or bariatric surgery, and by high-challenging weight loss targets. Male gender, higher BMI and concern for present health predicted weight loss > 10%, whereas concern for body appearance was associated with lower probability of attaining the desired weight loss targets. CONCLUSION A more precise definition of needs and expectations might help tailor treatment to individual patients, but attrition rates and target reach remain difficult to predict.

Abstract
Engagement denotes the extent to which, and how, individuals participate in weight management (WM) services. Effective WM services should generate meaningful outcomes and promote high participant engagement; however, research is predominantly focused on the former. Given that engagement is a poorly understood phenomenon, and that engagement-related concepts are often used synonymously (e.g., dropout and attrition), the engagement pathway is hereby introduced. This pathway defines key concepts (e.g., recruitment, adherence, attrition) and their relationships in the enrolment, intervention, and maintenance stages of treatment. The pathway will help researchers and practitioners better understand engagement-related concepts whilst encouraging greater conceptual consistency between studies.

Development of a patient experience questionnaire to improve lifestyle services in primary care. Prim Health Care Res Dev 2018; 19:542-552.

Abstract
AimWe developed a self-report tool to assess patients' experiences with lifestyle services in team-based primary care and pilot tested the questionnaire as part of a lifestyle intervention study to reverse metabolic syndrome. BACKGROUND Older client satisfaction questionnaires have been generally inadequate for quality improvement purposes, as they have been focused mainly on interpersonal skills of providers and/or in the context of one disease. New approaches to assessing the patient experience of lifestyle programs in primary care are needed and could inform quality improvement efforts over time. METHODS The first phase in developing the questionnaire involved a group-administered questionnaire distributed to 38 healthcare providers in five groups to prioritize variables to include in the survey. Concepts were taken from a previous review of available questionnaires assessing primary care services. The draft questionnaire was reviewed by 11 participants from a lifestyle program using think-aloud cognitive interviewing techniques. The modified self-administered questionnaire (paper and online versions) was then pilot tested with 164 recipients of a nutrition and physical activity intervention program.FindingsProviders ranked the top variables to include in the questionnaire as: 'trust,' 'general communication,' 'first-contact accessibility,' 'whole-person care,' and 'respectfulness.' After cognitive interviewing and revisions, 21 multiple choice and two open-ended questions were used for pilot testing. Pilot testing identified additional minor wording changes that were needed for clarity, a decreased number of questions for redundant concepts, and decreased options for ceiling effects, resulting in 20 multiple choice and one open-ended question. CONCLUSIONS The modified self-administered patient experience questionnaire to assess lifestyle services in primary care has undergone rigorous development. Further validation is needed. The assessment of patient experience of lifestyle programs can be used to supplement other data to assess the overall effectiveness of such programs.

Abstract
Engaging patients in a group-based weight loss program is a challenge for the acute-care hospital outpatient setting. To evaluate the feasibility, effectiveness and cost-effectiveness of a telephone-based weight loss service and an existing face-to-face, group-based service a non-randomised, two-arm feasibility trial was used. Patients who declined a two-month existing outpatient group-based program were offered a six-month research-based telephone program. Outcomes were assessed at baseline, two months (both groups) and six months (telephone program only) using paired t tests and linear regression models. Cost per healthy life year gained was calculated for both programs. The telephone program achieved significant weight loss (-4.1 ± 5.0 %; p = 0.001) for completers (n = 35; 57 % of enrolees) at six months. Compared to the group-based program (n = 33 completers; 66 %), the telephone program was associated with greater weight loss (mean difference [95%CI] -2.0 % [-3.4, -0.6]; p = 0.007) at two months. The cost per healthy life year gained was $33,000 and $85,000, for the telephone and group program, respectively. Telephone-delivered weight management services may be effective and cost-effective within an acute-care hospital setting, likely more so than usual (group-based) care.

Abstract
This study collates existing evidence regarding weight loss among overweight but otherwise healthy adults who use commercial weight-loss programs. Systematic search of 3 databases identified 11 randomized controlled trials and 14 observational studies of commercial meal-replacement, calorie-counting, or pre-packaged meal programs which met inclusion criteria. In meta-analysis using intention-to-treat data, 57 percent of individuals who commenced a commercial weight program lost less than 5 percent of their initial body weight. One in two (49%) studies reported attrition ≥30 percent. A second meta-analysis found that 37 percent of program completers lost less than 5 percent of initial body weight. We conclude that commercial weight-loss programs frequently fail to produce modest but clinically meaningful weight loss with high rates of attrition suggesting that many consumers find dietary changes required by these programs unsustainable.

Abstract
OBJECTIVES Current research in the field of childhood weight management (WM) effectiveness is hampered by inconsistent terminology and criterion for WM programme completion, alongside other engagement-related concepts (e.g. adherence, dropout and attrition). Evidence reviews are not able to determine conclusive intervention effectiveness because of this issue. This study aims to quantify how various completion criterion impacts upon on: 1) the percentage of WM completers; 2) the standardised body mass index (BMI SDS) reduction; and 3) the predictors of WM completion. STUDY DESIGN A methodological, sensitivity analysis to examine how differential completion criterion affect programme outcomes and predictors. METHODS Secondary data of 2948 children were used. All children attended a MoreLife WM programme between 2009 and 2014. The completion criterion was incrementally adjusted by 10% (i.e. completer attends 10%, 20%, 30%... of sessions) for research aims 1-2, with the percentage of completers and change in BMI SDS calculated at each increment. For aim 3, the stability (strength, direction and significance) of the predictors were examined when using the completion criterion of four alternative studies against our previous study (completion ≥70% attendance). RESULTS The volume of programme completers decreased in a linear manner as the completion criterion became more stringent (i.e. 70-100% attendance). The change in BMI SDS conversely became incrementally greater. The strength, direction and significance of the predictors was highly dependent on the completion criterion; the odds ratio varied by 24.2% across a single predictor variable (delivery period). The degree of change is evidenced in the paper. CONCLUSIONS Inconsistent completion criterion greatly limits the synthesis of programme effectiveness and explains some of the inconsistency in the predictors of engagement. Standardised criterion for engagement-related terminology are called for.

Abstract
Lifestyle intervention programmes are efficacious in the management of obesity but often report poor attendance and adherence rates that hinder treatment effectiveness and health outcomes. The aim of this systematic review is to identify (i) barriers to behaviour change and (ii) predictors of adherence to lifestyle intervention programmes in adults with obesity. Studies were identified by systematically reviewing the literature within Medline, PsycINFO, CINAHL, SPORTDiscus and Web of Science from inception to August 2016. Barriers to behaviour change include poor motivation; environmental, societal and social pressures; lack of time; health and physical limitations; negative thoughts/moods; socioeconomic constraints; gaps in knowledge/awareness; and lack of enjoyment of exercise. The most prominent predictors of adherence include early weight loss success, lower baseline body mass index (BMI), better baseline mood, being male and older age. The findings within this review provide novel insight to clinicians working in obesity and have important implications for lifestyle intervention programme design. Barriers to behaviour change need to be addressed early in treatment, with lifestyle intervention individualized accordingly. Predictors of adherence should also be taken into careful consideration, with negative moods and unrealistic weight loss expectations discussed at the outset. If adherence is improved, treatment effectiveness, health outcomes and the ultimate burden of chronic diseases could also be improved.

Abstract
OBJECTIVES To investigate whether training individuals from the personal networks of adults with obesity in the skills of motivational interviewing enhances the anthropometric and psychological outcomes of a cognitive-behavioural weight loss intervention. METHODS Adults with obesity (N = 201) were randomised to participate in 26 sessions of cognitive behaviour therapy (CBT) for weight loss either alone (CBT-A) or with the addition of a support person (CBT-SP). Outcomes were assessed at the end of the 12-month intervention and at a follow-up one year later. RESULTS Analyses indicated negligible additive effect for the CBT-SP versus the CBT-A condition, although the quality of the patient's relationship with their support person predicted the anthropometric outcomes. Across conditions, significant improvements were observed for all anthropometric (weight, body mass index, and waist circumference) and psychological (self efficacy, weight-related quality of life, weight satisfaction, and binge eating) variables between baseline and post-treatment, and baseline and the follow-up. CONCLUSIONS The benefits of the cognitive-behavioural weight loss program were found to extend to psychological variables. Yet the lack of evidence for the additive benefits of including support people in treatment suggests a need to develop more effective training programs for support people in weight management.

Abstract
Poor adherence to lifestyle intervention remains a key factor hindering treatment effectiveness and health outcomes for adults with obesity. The aim of this systematic review and meta-analysis is to determine if behavioural treatment strategies (e.g. goal setting, motivational interviewing, relapse prevention, cognitive restructuring etc.) improve adherence to lifestyle intervention programmes in adults with obesity. Randomized controlled trials that investigated the use of behavioural treatment strategies in obesity management were identified by systematically reviewing the literature within Medline, PsycINFO, CINAHL, SPORTDiscus and Web of Science from their inception to August 2016. This meta-analysis shows that behavioural treatment interventions have a significant positive effect on session attendance (percentage) and physical activity (total min/week) in adults with obesity (M = 17.63 (95% confidence interval (CI) = 10.77, 24.50), z =5.0337, P < 0.0001 and M = 105.98 (95% CI = 58.64, 153.32), z =4.3878, P < 0.0001, respectively). This meta-analysis of randomized controlled trials provides evidence that behavioural treatment strategies improve adherence to lifestyle intervention programmes in adults with obesity. These strategies should be routinely incorporated into lifestyle intervention, obesity management and weight loss programmes with the aim of improving engagement and adherence. If adherence were improved, treatment effectiveness, health outcomes and the ultimate burden of chronic disease could also be improved.

Abstract
Therapeutic alliance is a well-recognized predictor of patient outcomes within psychological therapy. It has not been applied to obesity interventions, and Bordin's theoretical framework shows particular relevance to the management of obesity in primary health care. This cross-sectional study of a weight management programme in general practice aimed to determine if therapeutic alliance was associated with patient outcomes. The Working Alliance Inventory short revised version (WAI-SR) was administered to 23 patients and 11 general practitioners (GPs) at the end of a 6-month weight management programme. Use of the WAI-SR indicated that the strength of therapeutic alliance varied between different patient-GP relationships in this pilot intervention. A robust therapeutic alliance was strongly associated with patient engagement in the weight management programme indicated by number of appointments. It was also associated with some general health and quality of life outcomes. These are promising results that require confirmation with larger studies in primary health care. The measurement of therapeutic alliance using the WAI-SR may predict patient attendance and outcomes in obesity interventions in primary healthcare settings.

Kwitowski M, Bean MK, Mazzeo SE. An exploration of factors influencing attrition from a pediatric weight management intervention. Obes Res Clin Pract 2016; 11:233-240.

Abstract
Pediatric obesity is a public health concern. High attrition from treatment negatively impacts outcomes, particularly among lower income and ethnic minority populations. NOURISH+ is a parent-exclusive childhood weight management treatment targeting at-risk children aged 5-11 years who are overweight or obese. The current study sought to enhance understanding of attrition among at-risk families. NOURISH+ participants completed a survey assessing barriers to treatment adherence. Among low-income, racially diverse families, practical barriers are pressing concerns. The NOURISH+ parent-exclusive approach, although empirically supported, appears inconsistent with caregivers' expectations. Minimizing practical barriers and enhancing child engagement might reduce attrition and improve outcomes.

Nobles J, Griffiths C, Pringle A, Gately P. Design programmes to maximise participant engagement: a predictive study of programme and participant characteristics associated with engagement in paediatric weight management. Int J Behav Nutr Phys Act 2016; 13:76. [PMID: 27430218 PMCID: PMC4949908 DOI: 10.1186/s12966-016-0399-1] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2015] [Accepted: 06/15/2016] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Approximately 50% of paediatric weight management (WM) programme attendees do not complete their respective programmes. High attrition rates compromise both programme effectiveness and cost-efficiency. Past research has examined pre-intervention participant characteristics associated with programme (non-)completion, however study samples are often small and not representative of multiple demographics. Moreover, the association between programme characteristics and participant engagement is not well known. This study examined participant and programme characteristics associated with engagement in a large, government funded, paediatric WM programme. Engagement was defined as the family's level of participation in the WM programme. METHODS Secondary data analysis of 2948 participants (Age: 10.44 ± 2.80 years, BMI: 25.99 ± 5.79 kg/m(2), Standardised BMI [BMI SDS]: 2.48 ± 0.87 units, White Ethnicity: 70.52%) was undertaken. Participants attended a MoreLife programme (nationwide WM provider) between 2009 and 2014. Participants were classified into one of five engagement groups: Initiators, Late Dropouts, Low- or High- Sporadic Attenders, or Completers. Five binary multivariable logistic regression models were performed to identify participant (n = 11) and programmatic (n = 6) characteristics associated with an engagement group. Programme completion was classified as ≥70% attendance. RESULTS Programme characteristics were stronger predictors of programme engagement than participant characteristics; particularly small group size, winter/autumn delivery periods and earlier programme years (proxy for scalability). Conversely, participant characteristics were weak predictors of programme engagement. Predictors varied between engagement groups (e.g. Completers, Initiators, Sporadic Attenders). 47.1% of participants completed the MoreLife programme (mean attendance: 59.4 ± 26.7%, mean BMI SDS change: -0.15 ± 0.22 units), and 21% of those who signed onto the programme did not attend a session. CONCLUSIONS As WM services scale up, the efficacy and fidelity of programmes may be reduced due to increased demand and lower financial resource. Further, limiting WM programme groups to no more than 20 participants could result in greater engagement. Baseline participant characteristics are poor and inconsistent predictors of programme engagement. Thus, future research should evaluate participant motives, expectations, and barriers to attending a WM programme to enhance our understanding of participant WM engagement. Finally, we suggest that session-by-session attendance is recorded as a minimum requirement to improve reporting transparency and enhance external validity of study findings.
