About this study
Official title: Feasibility of Conducting a Randomized Controlled Trial Comparing Standard FBT and Guided Self-Help FBT for Adolescent Anorexia Nervosa
This study examines a parent only Guided Self-Help for Family Based Treatment (GSH-FBT) for adolescents between the ages of 12 and 18 diagnosed with Anorexia Nervosa. Preliminary data collected in a previous study suggest that a Guided Parental Self-Help Version of FBT (GSH-FBT) has similar outcomes as therapist provided FBT.
Read the detailed description
In this study, families will be randomized to either receive 12 weekly online sessions of Guided Self-Help for Family Based Treatment (GSH-FBT), or 15 sessions of online, professionally delivered, standard FBT over the course of 6 months. Potential subjects will be recruited from Stanford University, McMaster University, other local medical programs and clinics, and online advertisement to the population at large. If participants are deemed eligible, participants will be invited for a baseline interview during which the investigators will conduct interviews and collect questionnaire measures. Participants will complete a follow-up interview at the end of treatment and 3-month after end of treatment.

A online website provided to parents containing information learned in Family Based Treatment and up to 12 coaching sessions with a therapist.
Family Based TreatmentBehavioural
Also called FBT
Standard Family Based Treatment provided for up to 15 sessions.
| Study group | Role | What they receive |
|---|---|---|
| FBT | Active comparator | Family Based Treatment (FBT) includes up to 15 session (50-60 minutes) with a trained therapist. Receives: Behavioral: Family Based Treatment |
| FBT-GSH | Experimental | Family Based Treatment Guided Self-Help (FBT-GSH) includes an online website with educational videos, readings, discussion groups, and journals.

What is being measured
The primary outcome is the main question the study is designed to answer.
Recruitment Rate
Number of participants enrolled in the study per month.
Measured: Assessed through the end of recruitment (about one year)
Treatment Retention Rate
The count of participants who did not stop treatment before finishing their randomized treatment course (FBT-V or GSH-FBT).
Measured: Up to 6 months
Study Retention Rate
The number of participants who provided information for the end of treatment assessment and 3-month follow up assessment.
Measured: Up to 9 months
Treatment Acceptability Ratings
To assess treatment acceptability, the study used the Cooperation and Helpfulness sub-scales of the Helping Alliance Questionnaire (HAQ). The HAQ was administered to parents after session 1 and 8. The subscales, Helpfulness and Cooperation, are scored on a Likert scale from "Strongly feels it's true" (+3) to "Strongly feel it's not true" (-3). The sub-scales' total scores ranges are 15- to 15 for Helpfulness and -18 to 18 for Cooperation. A higher score indicates a better outcome. The average score was calculated if more than one parent responded.
Measured: Session 1 and Session 8 (approximately 5 minutes to complete questionnaire)
Treatment Acceptability Ratings
To assess treatment acceptability, the study used the Therapist Suitability and Patient Expectancy measure (TSPE). The TSPE was administered to parents after session 1. The scale is measured from 0-10 (with 0 as the lowest rating and 10 as the highest rating). The average score was calculated if more than one parent responded. A higher score on the TSPE indicates a better outcome.
Measured: Session 1 (approximately 5 minutes to complete questionnaire)
Number of Treatment Sessions Attended
The number of sessions completed by the the participant with the client in treatment is the actual, not planned, number of sessions actually conducted.
Measured: Through end of treatment (up to approximately 6 months)
Serious Adverse Events
Number of events in which a participant required hospitalization
Measured: Baseline through end of treatment period (up to 6 months)
