Multifamily Guided Self-Help Family-Based Treatment (MF-GSH-FBT)

Not Applicable

Completed

Brief Summary: This is a study testing whether an online Multifamily Guided Self-Help Family Based Treatment (FBT) for Anorexia Nervosa in adolescents aged 12 to 17 is acceptable and useful to families. This online Multifamily Guided Self-Help version of FBT consists of 12 weekly 60-minute telemedicine groups made up of parents from 4-5 families of young people with AN, coupled with access to an online guided self-help platform over the course of 6 months. The feasibility of online Guided Self-Help Family-Based Treatment for Anorexia is unknown, and the investigators hope to identify an adequate treatment for those who do not have access to in-person FBT.

Detailed Description: Previous research has shown that Family-Based Treatment (FBT) is an effective treatment for Anorexia Nervosa. In the first Phase of FBT, parents are encouraged to take charge of the process of renourishing their child with Anorexia. Then, once the young person with Anorexia becomes better nourished and is managing to eat in a more sustainable way, the treatment moves to Phase 2. In Phase 2 of FBT, the focus is on helping parents to step back and support their child to regain their independence around eating. Once this happens, the treatment moves to Phase 3, where the family begins to move forward with their lives in a normal way, no longer focused on the eating disorder.

The investigators hope to learn whether an adaptation of FBT, called online Multi-Family Guided Self-Help FBT, is feasible and acceptable for families of young people with Anorexia.

The 'Self-Help' aspect of the treatment consists of a series of educational videos about how to help a child with Anorexia, which parents watch on an online platform. The 'Multifamily' and 'Guided' aspects of the treatment consists of weekly meetings by Zoom for a group of parents of young people with Anorexia, with a facilitator present to guide a group discussion around whether parents feel they understood the content of the videos and whether the content is helpful.

Arm && Interventions

Group	Intervention	Description
Multifamily Guided Self-Help Family-Based Treatment (MF-GSH-FBT)	Multi-Family Guided Self-Help FBT	Treatment consists of up to 12 once-weekly online group sessions, where groups are made up of parents from 4-5 different families of young people with Anorexia. Group sessions will last approximately 50-60 minutes. Prior to each group session, parents watch recorded videos about how parents can help their child with Anorexia. Only parents, and not the young person with Anorexia, attend the group sessions.

Primary Outcome Measures

Name	Time	Method
Treatment Retention Rate	Through end of treatment (up to approximately 4 months)	The count of participants who did not stop treatment before finishing the 12-session parent groups
Recruitment Rate	Assessed through the end of recruitment (about one year)	Number of participants enrolled in the study per month.
Number of Treatment Sessions Attended	Through end of treatment (up to approximately 4 months)
Treatment Acceptability as Measured by Helping Alliance Questionnaire	Through end of treatment (up to approximately 4 months)	The Helping Alliance Questionnaire (HAQ) is an 11-item questionnaire that measures the quality of the therapist-patient relationship and will be completed by parents.
Treatment Acceptability as Measured by Therapy Suitability and Patient Expectancy questionnaire	Through end of treatment (up to approximately 4 months)	The Therapy Suitability and Patient Expectancy (TSPE) measures perceptions of the suitability and expectancy of the treatment provided and will be rated by parents.

Secondary Outcome Measures

Name	Time	Method
Expected Body Weight	Baseline and EOT (up to approximately 4 months)	Expected Body Weight (EBW) percentages for the adolescent with Anorexia will be calculated using Center for Disease Control metrics in children and adolescents.
Eating Disorder Cognitions	Baseline and EOT (up to approximately 4 months)	Eating Disorder Examination (EDE): This is a standardized measure that measures the severity of the characteristic psychopathology of eating disorders. It is to be administered by assessor to the adolescent with Anorexia at baseline and EOT.
