Study type
Interventional
Description of intervention(s) / exposure
The present study aims to evaluate a brief intuitive eating intervention adapted for adolescents using a single-arm crossover-style design. A non-randomised control group will be used. Allocation will be done on a convenience basis; upon their recruitment schools can select to take part in the first half of the term or the second half of the term based on their own scheduling preferences. The intervention will be facilitated face-to-face in four school classrooms (2 intervention, 2 non-randomised control) by a certified intuitive eating counsellor. In total, there will be 5x 1 hour sessions delivered weekly for five weeks. No homework or out-of-hours learning will be required. The in-class lessons will cover key intuitive eating skills and emotional regulation, and self-care tools, adapted from the evidence-based intuitive eating model (Tribole & Resch, 1995) and designed to fit within Aotearoa New Zealand's Health & Physical Education (HPE) curriculum. They will be a conducted as a series of interactive activities, including lecture-style lessons, group discussions, small group/paired activities, and creative worksheets. Adherence will be measured using session attendance checklists. The facilitator will use a scripted guide in all sessions to ensure framework adherence. Students will be in classroom groups of approximately 30 and will be provided with a student workbook designed for the purposes of this study to consolidate student learning.

Prevention
Comparator / control treatment
Non-randomised control groups will consist of two classrooms (group A) that will provide baseline data and have delayed access to the intervention. Group A classrooms will complete regular teacher-directed HPE lessons for the first five weeks of term (while active classroom conditions are completed) and then commence the intervention after two other classrooms (group B) have completed it. Teachers in group A will be asked to provide a brief overview of their lesson planning for the start of term so key differences can be identified between their lessons and the intervention content.

Outcomes
Primary outcome [1] 332700 0
Intuitive eating assesed by the Early Adolescent Intuitive Eating Scale (IES-EA), an adaptation of the IES-2 (Tylka & Kroon Van Diest, 2013)
Timepoint [1] 332700 0
Data will be collected at four time-points, using a crossover-style design. (1) Baseline (groups A & B), (2) five weeks after baseline (group A) or end of intervention (group B), (3) end of intervention (group A) and five weeks after intervention (group B), (4) four weeks after time-point 3 (groups A & B).
Primary outcome [2] 332701 0
Positive body image and body satisfaction as measured by the Body Appreciation Scale (Avalos et al., 2005).
Timepoint [2] 332701 0
Data will be collected at four time-points, using a crossover-style design. (1) Baseline (groups A & B), (2) six weeks after baseline (group A) or end of intervention (group B), (3) end of intervention (group A) and six weeks after intervention (group B), (4) four weeks after time-point 3 (groups A & B).
Secondary outcome [1] 414407 0
Acceptability as measured by structured questions and a five-point Likert-type scale from 1 (strongly disagree) to 5 (strongly agree). Questions will index their attitudes towards the intervention as related to key components of feasibility research: accessibility and implementation, demand and practicality, and integration and expansion (Bowen et al., 2009).
Timepoint [1] 414407 0
Secondary data will be collected at the end of the intervention (at the conclusion of the final session) for both Group A and Group B.

Summary
Brief summary
Intuitive Eating (IE) is an approach to eating that is characterised by attunement to internal cues and the use of those cues as a guide for what, when, and how much to eat (Tribole & Resch, 2012; Tylka, 2006). IE posits that this attunement, a skill called interoceptive awareness, can foster an increased ability to adequately and compassionately meet one’s physical and psychological needs in a way that contributes to overall well-being. The IE framework endeavours to remove over-reliance on external cues, such as calorie tracking, and diet protocols, by encouraging an increased focus on internal cues.

Cross-sectional research indicates that IE is a skill worth fostering, with considerable evidence for strong inverse relationships between IE and indices of disordered eating, including emotional eating, external eating, and binge-purge behaviours. Further, strong relationships with indicies of psychological health, including self-esteem, body image, and satisfaction with life have also been found (Lindaron et al, 2021).The IE framework is gaining popularity in health promotion in a variety of contexts (Boucher et al., 2016; Bush et al., 2014; Cole & Horacek, 2010), given longitudinal evidence that IE is protective against the development of disordered eating (Hazzard et al., 2021).

The study seeks to explore whether or not a brief intuitive eating intervention may be an effective health promotion strategy for year 7 & 8 students in Aotearoa New Zealand. Key outcomes are feasibility and acceptability, so the research team is looking to gather feedback from both students and teachers to shape future iterations of the intervention which can be more robustly tested using a randomised controlled trial (RCT).
