Trial Outcomes & Findings for Family-Based Interoceptive Exposure for Avoidant Restrictive Food Intake Disorder (NCT NCT06110806)

NCT ID: NCT06110806

Last Updated: 2026-06-10

Results Overview

An MBIE-adapted Therapy Suitability and Acceptability Scale will average specific items from patient's view on match of therapy to the problem, responsiveness of intervention to different treatment challenges, degree of unexpected discomfort related to treatment, interest in using therapy experiences beyond the therapy session. This scale includes 10-20 items, depending on the session content, and is measured using a Likert scale from 1-7. Scores are calculated using a sum of all items, with a possible range of scores of 10 to 140. Higher scores indicate greater suitability of the treatment for the child and expectancy of success with the intervention.

Mindfulness-based Interoceptive Exposure (MBIE)
Outpatient therapy for individuals with ARFID using mindfulness and exposures in a family-based therapy approach. MBIE: MBIE administered over 20 sessions, targets increasing psychological flexibility and acceptance by decreasing avoidance and attempts to control distressing or undesired internal experiences, and includes psychoeducation, targeted mindfulness practice, in vivo exposures, and counter-conditioning.

PRIMARY outcome

Timeframe: up to 6 months

Population: Data not collected because 6 month visit not completed due to early termination of study.

An MBIE-adapted Therapy Suitability and Acceptability Scale will average specific items from patient's view on match of therapy to the problem, responsiveness of intervention to different treatment challenges, degree of unexpected discomfort related to treatment, interest in using therapy experiences beyond the therapy session. This scale includes 10-20 items, depending on the session content, and is measured using a Likert scale from 1-7. Scores are calculated using a sum of all items, with a possible range of scores of 10 to 140. Higher scores indicate greater suitability of the treatment for the child and expectancy of success with the intervention.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Session 20, at week 20

Adherence of the MBIE intervention will be measured with ratings of therapy tapes of 20 sessions. Adherence will be calculated using a dichotomous scale (yes/no) of items rating the extent of use of treatment elements and the quality of delivery of the intervention. As the number of treatment elements vary, and some items are reverse coded, the minimum, maximum, and scaling are not utilized. Per item adherence can range from 0 to 100%.

Acceptability of data collection and assessment procedures will be measured using participant ratings of acceptability for total time and frequency on an investigator-derived scale. This measurement includes items assessing the (1) tolerability and (2) ease of completing laboratory, behavior, and self-report tasks using a 15 mm visual analog scale. Questions are scored from 0-15 and then all scores are summed for an acceptability score. Ranges include 0-120 at baseline, 0 to 30 at Session 5, 0-120 at Session 10, and 0-120 at Session 20. Higher scores indicate greater acceptability of study assessments.

Timeframe: up to 6 months

Population: Data not collected because 6 month visit not completed due to early termination of study.

The number of MBIE sessions required to achieve a clinically meaningful outcome and acceptable tolerability using a Functional Food Hierarchy. This measurement rates a minimum of 11 food items on a scale of 0-10 at 10 levels of the hierarchy (subjective units of distress). Scores range from 0-100 with higher scores indicating lower avoidance/increased consumption.

SECONDARY outcome

Timeframe: up to 6 months

Population: Data not collected because 6 month visit not completed due to early termination of study.

The number of MBIE sessions required to achieve a clinically meaningful outcome (consuming food rated as70 or higher on the Food Avoidance Scale). The Food Avoidance Scale is investigator-derived and includes 1 item rated on a scale of 0-100 with higher scores indicating consumption of more challenging/avoided foods.
