Your Body Is Your Home: The feasibility of an intuitive eating intervention for early adolescents

OBJECTIVE

Intuitive eating (IE) is an emerging health promotion framework which has shown promise in the prevention and early intervention of disordered eating (DE) behavior in adults. This study sought to extend this work by assessing the feasibility and preliminary efficacy of a 5-week IE intervention, "Your Body is Your Home," delivered in school classrooms for early adolescents aged 11-13.

METHODS

The present study utilized a quasi-experimental design. Eligibility criteria were defined a priori and published in a registered protocol. Four classrooms (n = 128 student participants) were recruited into two streams, and self-report questionnaires were administered at pre-test, post-test, and 4-week follow-up. The questionnaires included the Intuitive Eating Scale for Early Adolescents (IES-2-EA), the Body Appreciation Scale (BAS-2), and the WHO Wellbeing Index (WHO-5). Linear mixed models were used to conduct preliminary efficacy testing.

RESULTS

The results indicate that a brief classroom-based IE intervention is feasible and acceptable for both students and teaching staff; retention, fidelity, and attendance targets were achieved. Students and teachers rated all five sessions of the intervention as a highly feasible method of health promotion. Further, preliminary efficacy data suggest IE interventions aimed at early adolescents may be a feasible way of improving certain aspects of IE (p < .001) in male and female participants, and body appreciation (p < .001) in male participants.

DISCUSSION

The study provides preliminary support for the implementation and evaluation of an IE intervention as part of school-based health promotion and offers preliminary effect size estimates for a larger-scale randomized trial.

PUBLIC SIGNIFICANCE

Existing evidence suggests that IE may be a useful framework through which relationships with food and the body can be improved. The present study seeks to extend this work by adapting the framework for early adolescents (among whom the framework is not well understood) and examining feasibility, acceptability, and preliminary changes to several health and well-being metrics following a 5-week school-based intervention.

Bringing an end to diabetes stigma and discrimination: an international consensus statement on evidence and recommendations

People with diabetes often encounter stigma (ie, negative social judgments, stereotypes, prejudice), which can adversely affect emotional, mental, and physical health; self-care, access to optimal health care; and social and professional opportunities. To accelerate an end to diabetes stigma and discrimination, an international multidisciplinary expert panel (n=51 members, from 18 countries) conducted rapid reviews and participated in a three-round Delphi survey process. We achieved consensus on 25 statements of evidence and 24 statements of recommendations. The consensus is that diabetes stigma is driven primarily by blame, perceptions of burden or sickness, invisibility, and fear or disgust. On average, four in five adults with diabetes experience diabetes stigma and one in five experience discrimination (ie, unfair and prejudicial treatment) due to diabetes, such as in health care, education, and employment. Diabetes stigma and discrimination are harmful, unacceptable, unethical, and counterproductive. Collective leadership is needed to proactively challenge, and bring an end to, diabetes stigma and discrimination. Consequently, we achieved unanimous consensus on a pledge to end diabetes stigma and discrimination.

Intuitive Eating Scale-2-EA: Psychometric properties and factor structure of the adapted IES-2 for early adolescents

PURPOSE

Intuitive Eating (IE) is an approach to eating characterised by attunement to intrinsic cues, and using those cues to guide behaviours related to food and eating. Tylka and Kroon Van Diest's (2008) Intuitive Eating Scale (IES-2) is well-validated in adults, but not yet among early adolescents. The current study was designed to adapt and validate a version suited for use in early adolescence (IES-2-EA).

METHODS

Data collected from two independent samples of adolescents aged 11 to 13 (N = 471) were structurally examined using exploratory factor analysis (EFA), with a subsequent confirmatory factor analysis (CFA) to confirm hypothesised model fit. Relationships between scores on the IES-2-EA and validated measures of actual-ideal body size discrepancy, body appreciation, interoceptive awareness, and psychological distress were also examined.

RESULTS

The adapted 17-item IES-2-EA had a three-factor structure with several key differences from the original version developed for adults. Moderate-to-strong correlations were found between scores on the IES-2-EA, body appreciation, interoceptive awareness, actual-ideal body size discrepancy, and psychological distress in the first sample of adolescents (n = 245). Secondary CFA showed good model fit in the second sample of adolescents (n = 226).

CONCLUSION

The IES-2-EA is well-suited to measure intuitive eating behaviour among early adolescents. The 17 items reflect a three-component structure similar to that seen in adults completing the IES-2. These early data suggest the adapted IES-2-EA has evidence of reliability and validity; it may be an effective measure for research and clinical use.

Eating behaviour, body image, and mental health: updated estimates of adolescent health, well-being, and positive functioning in Aotearoa New Zealand

Introduction Body image dissatisfaction and its associated challenges have been related to poorer health outcomes among adolescents worldwide, including disordered eating behaviour, depression, and anxiety. However, current prevalence estimates of these issues in Aotearoa New Zealand or, relatedly, the estimates of positive attitudes and behaviours, such as intuitive eating and body appreciation are dated. Aim The primary aim of this paper was to provide updated estimates for a variety of constructs related to eating behaviours and body image, sourced from a diverse range of early adolescent participants. Methods For this report, a brief online survey was advertised to adolescents throughout Aotearoa New Zealand (n  = 893) via school and community noticeboards. Results Approximately one-in-three male participants and one-in-two female participants reported body image dissatisfaction. One in four participants reported clinically significant symptoms of depression and anxiety. Discussion Given such issues, there is clearly still much progress to be made in advancing positive health among early adolescents. Identifying potentially protective constructs such as intuitive eating and body appreciation may offer guidance into the best targets for prevention and early intervention.

Developing digital mental health tools for youth with diabetes: an agenda for future research

Youth living with diabetes face a concurrent challenge: managing a chronic health condition and managing the psychosocial and developmental changes that are characteristic of adolescence and young adulthood. Despite these unique challenges, psychological support is often difficult for youth with diabetes to access due to a lack of trained mental health professionals and other resource constraints. Digital wellbeing tools offer the potential to improve access to psychological support for this population. However, very few digital wellbeing tools exist for youth with diabetes. Of those that do exist, very few are evidence-based therapies, undermining their contribution to the field. Given the increasing global prevalence of diabetes in young people, the support necessitated by the challenges experienced by this population is not always accessible in a face-to-face setting and cannot be effectively scaled to meet demand. To support the health and wellbeing of youth with diabetes, there is a clear need to develop digital interventions that are widely accessible to users, but, more saliently, grounded in empirical evidence that supports their efficacy. Thus, the purpose of this paper is to offer an agenda for future research, including insights into which psychological techniques and behavioral change theories may be a good conceptual fit for digital mental health interventions, and how these tools may be best developed and utilized by the individuals that need them. Scalable, evidence-based wellbeing tools for this population are urgently required to improve psychological outcomes, and potentially, improve the equity of service access.

Outcomes of intuitive eating interventions: a systematic review and meta-analysis

Intuitive eating (IE) is an approach to health promotion that fosters a positive relationship with food and the body. The objective of this review was to aggregate and analyse the literature on IE interventions, thereby offering an early investigation of methodological approaches to intervention. This review was conducted in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA) guidelines. Searching was conducted in four electronic databases. Studies were eligible for inclusion if they delivered an IE intervention and used the Intuitive Eating Scale (IES). Nine studies were included in this review. Six were eligible for meta-analysis, though only outcomes on the IES were examined; all other measures were examined individually. All interventions led to improvements on measures of IE, with a large pooled effect size (1.50 [1.15, 1.85]) and positive changes on a variety of other outcomes relating to health. This pattern preliminarily suggests that IE interventions change psychological processes as intended and can be useful in promoting health behaviour. The present review offers a synthesis of existing approaches to IE interventions and an evaluation of which specific variants appear to be more effective. This paper provides a basis upon which future interventions can be developed to improve approaches to psychoeducation.Clinical ImplicationsInterventions contributed to improvements in measures of IE lasting up to 6 months.Interventions contributed to positive changes on outcomes such as quality of life, body image, and body appreciation.Self-management through IE-based interventions may be feasible and effective.

Intuitive Eating Scale-2: psychometric properties and clinical norms among individuals seeking treatment for an eating disorder in private practice

PURPOSE

Intuitive Eating (IE) is an approach to eating designed to facilitate a positive relationship with food. Its use in clinical settings and in the community is rapidly growing in popularity. The Intuitive Eating Scale 2 (IES-2) is a widely used measure that indexes intuitive eating motivations and behaviour, however evidence of its validity in populations with clinical eating disorders remains scarce. The objective of the proposed study was thus to evaluate the factor structure of the IES-2 in a large sample of individuals seeking treatment for eating disorders in private practice.

METHODS

Data collected from 569 women and men aged 12-68 years seeking treatment for an eating disorder in one of eight specialist private outpatient eating disorder clinics were examined using confirmatory factor analysis (CFA). Relationships between IES-2 scores and measures of psychopathology were also examined.

RESULTS

Results were relatively consistent with the purported four-factor structure of the IES-2. The measure displayed strong construct validity and good internal consistency. Scores on the IES-2 were inversely associated with scores of depression, anxiety, and disordered eating, providing evidence for divergent validity of the measure. Clinical norms are provided for anorexia nervosa (AN) spectrum disorders and bulimia nervosa (BN) spectrum disorders, as well as for the clinical sample as a whole.

CONCLUSION

Findings suggest that the IES-2 may be an appropriate measure for evaluating behaviours relating to IE in community outpatient eating disorder settings, and provide further evidence for the association between IE and positive health outcomes.
