An interventional study of Family Based Treatment-Primary Care and Family-Based Treatment in Eating Disorders, sponsored by Mayo Clinic. Enrolling by invitation at 1 site in United States. Open to participants aged 7 Years to 18 Years. Per ClinicalTrials.gov, last updated 2026-02-05.

The purpose of this study is to test the feasibility of a RCT of a new treatment for children and adolescents with eating disorders characterized by dietary restriction and/or weight loss or failure to gain expected weight. The treatment, which is called Family-Based Treatment for Primary Care (or FBT-PC for short), is based on Family-Based Treatment, the gold standard outpatient eating disorder treatment for children and adolescents.
In the United States, half a million adolescents suffer from an eating disorder. With only 66 certified providers nationally, Family-Based Treatment (FBT), a first-line evidence-based treatment for adolescent eating disorders, is not readily available to most families. This provider shortage leaves most young patients without care and undoubtedly contributes to the chronicity and lethality of these conditions. Patients with eating disorders generally make their first contact with the healthcare system in primary care. As such, equipping primary care providers (PCPs) with effective means to treat these patients has potential to democratize care, improve rates of early intervention, and enhance patient outcomes. Family-Based Treatment for Primary Care (FBT-PC) is a novel intervention for delivery by a PCP in primary care that uses FBT strategies. Data support proof-of-concept for this adaptation. This study has several study aims. (1) Finalize the FB-PC intervention through an open case series. (2) Establish the feasibility and acceptability of FBT-PC for caregivers, patients, and PCPs in a pilot randomized controlled trial. Finally, (3) to test preliminary target engagement of FBT-PC and determine whether it is associated with improved caregiver self-efficacy and, through this mechanism, symptom remission. Remission will be defined as weight restoration to 95% of expected body weight and a score within 1 SD of community norms on the Eating Disorder Examination-Questionnaire. In addition, as (4) an exploratory aim analyses will be conducted to evaluate baseline characteristics of the sample to determine for whom the FBT-PC intervention is most beneficial. To accomplish all aims an open case series (n = 6) will be conducted, followed by a pilot trial in which 40 patients (ages 7-18 years) with restrictive eating disorders and their caregiver(s) will be randomly assigned to FBT-PC or a control condition of standard FBT. Families will attend up to 18 sessions over 6 months. Goals from the open case series (Aim 1) will include the development of tools for FBT-PC training and implementation, including treatment and training protocols and fidelity measures. Feasibility (Aim 2) will be assessed through an evaluation of recruitment and retention. Acceptability (Aim 2) will be evaluated using mixed methods surveys and interviews of caregivers, patients and PCPs on the topics of tolerability, fit, and burden. The degree to which FBT-PC engages the proposed mechanism of change, caregiver self-efficacy, to facilitate symptom remission will also be assessed (Aim 3). Effect sizes will be calculated for FBT-PC with a goal of ≥ 0.5, comparable with those found in FBT trials. Finally, baseline sample characteristics (Exploratory Aim) will be assessed including caregiver perceptions about their child's illness, referral method, length of illness, and symptom severity. Once feasibility, acceptability, and target engagement of the FBT-PC intervention have been established, these findings will be used in support of a large pragmatic clinical trial to evaluate the noninferiority of effectiveness of FBT-PC versus standard FBT.

Exclusion Criteria:
Subjects will receive up to 18 sessions of FBT-PC, delivered by a primary care provider, at their primary care clinic over 6 months.
Behavioral: Family Based Treatment-Primary Care
Subjects will receive up to 18 session of FBT, delivered by a specialist mental health provider at Mayo Clinic in Rochester, MN over 6 months.
Behavioral: Family-Based Treatment
Novel treatment that borrows key intervention strategies from standard family-based treatment. It uses trained primary care providers (PCPs), in consultation with a mental health provider, to deliver family-based treatment strategies in community-based clinics to increase caregiver self-efficacy to reverse their child's dietary restriction and weight loss.
Also known as: FBT-PC
Delivered by a mental health provider in a traditional mental health or eating disorder specialty setting. First-line evidence-based treatment for adolescent eating disorders that targets caregiver self-efficacy as a mechanism to facilitate weight restoration and ultimately symptom remission in adolescents.
Also known as: FBT
Rate of recruitment across 3 years
Recruitment rate will be tracked, with a goal of enrollment of 75% of eligible participants.
Time frame: Rate of recruitment at end of study (3 years)
Rate of retention across 3 years
Retention rate will be tracked, with a target retention rate (attendance at \>80% of sessions) of 70%.
Time frame: Rate of retention at end of study (3 years)
Mixed methods feedback survey at end of treatment (caregiver/patient)
This is a unique survey with quantitative (Likert scale rating/ yes/no questions) and qualitative (short answer) questions that assesses treatment satisfaction, acceptability of session frequency, length, and therapeutic alliance, as well as comfort and familiarity with treatment intervention components. Higher scores on Likert scales indicate greater satisfaction/acceptability.
Time frame: Assessed after the final session (within 6 months)
Rate of retention across 3 years
Rate of retention (defined as attendance at \> 80% of sessions) will be tracked, with a target of \<30% attrition.
Time frame: Rate of retention at end of study (3 years)
Parents versus Anorexia Scale (caregiver)
The degree to which FBT-PC engages the proposed mechanism of change, caregiver self-efficacy, will be assessed through this well-validated caregiver-report measure. This is a 7-item of caregiver self-efficacy that has been widely used in the eating disorder treatment literature. Items assess parental efficacy in the Maudsley model of family-based treatment for anorexia nervosa. Scores range from 5-35, with higher scores indicated higher self efficacy
Time frame: Monthly across the intervention (up to 6 months)
Parent Sense of Competency Scale (caregiver)
The degree to which FBT-PC engages the proposed mechanism of change, caregiver self-efficacy, will be assessed through this well-validated caregiver-report measure, a 17-item measure of general parenting competency beliefs. Items are rated on a 1-6 Likert scale, with scores ranging from 17-102, with higher scores indicating higher parenting competency beliefs.
Time frame: Monthly across the intervention (up to 6 months)
Eating Disorder Symptom Reduction (patient)
Patient weight restoration and reduction in behavioral/cognitive eating disorder symptoms as measured by the Eating Disorder Examination-Questionnaire or child Eating Disorder Examination-Questionnaire for patients ages 7-12. Higher scores on the 4 subscales and Global scale of these measures range from 0-6, with higher scores indicating more severe eating disorder symptomology.
Time frame: Pre/post intervention (up to 6 months)
Internalized Stigma of Mental Illness Scale (caregiver/patient)
The internalized stigma of having an eating disorder will be measured by the Internalized Stigma of Mental Illness Scale, a 20-item measure. This measure has been validated in populations of patients with eating disorders and will be modified to also be relevant for caregivers. Items are rated 1-4, with possible scores ranging from 29-116. Higher scores indicate higher internalized stigma.
Time frame: Pre/post intervention (up to 6 months)
Treatment experience feedback survey- Year 1 (provider)
Mixed methods surveys will be collected from primary care providers providing FBT-PC and within the participating practices, to assess their perceptions of their experience providing and referring to the intervention. HIgher scores on quantitative items (Likert scales rated 1-5) will indicated greater satisfaction.
Time frame: End of Year 1 of the study
Treatment experience feedback survey- Year 2 (provider)
Mixed methods surveys will be collected from primary care providers providing FBT-PC and within the participating practices, to assess their perceptions of their experience providing and referring to the intervention. HIgher scores on quantitative items (Likert scales rated 1-5) will indicated greater satisfaction.
Time frame: End of Year 2 of the study
