Processes of change in family therapies for anorexia nervosa: a systematic review and meta-synthesis of qualitative data

ObjectiveTo synthesise young person and family member perspectives on processes of change in family therapy for anorexia nervosa (AN), including systemic family therapy and manualised family-based treatments, to obtain an understanding of what helps and hinders positive change.MethodA systematic search of the literature was conducted to identify qualitative studies focussing on experiences of therapeutic change within family therapies for AN from the perspectives of young people and their families. Fifteen studies met inclusion criteria and underwent quality appraisal following which they were synthesised using a meta-synthesis approach.ResultsSix overarching themes were generated: "A holistic focus on the young person's overall development"; "The therapeutic relationship as a vehicle for change"; "The therapist's confinement to a script and its impact on emotional attunement"; "A disempowering therapeutic context"; "Externalisation of the eating disorder (ED)"; and "The importance of family involvement". Positive change was helped by understanding and support given to the young person's overall development including their psychological, emotional, social and physical wellbeing, positive therapeutic relationships, relational containment within the family system and externalising conversations in which young people felt seen and heard. Positive change was hindered by inflexibility in the treatment approach, counter-effects of externalisation, negative experiences of the therapist, a narrow focus on food-intake and weight, as well as the neglect of family difficulties, emotional experiences, and psychological factors.ConclusionsPositive change regarding the young person's eating-related difficulties ensued in the context of positive relational changes between the young person, their family members, the therapist and treatment team, highlighting the significance of secure and trusting relationships. The findings of this review can be utilised by ED services to consider how they may adapt to the needs of young people and their families in order to improve treatment satisfaction, treatment outcomes, and in turn reduce risk for chronicity in AN. This review synthesises the views of young people and their family members regarding their perspectives of therapeutic change within family therapies for Anorexia Nervosa (AN), including both manualised eating disorder-focussed family therapy models (family-based treatment; FBT and AN-focussed family therapy; FT-AN), as well as systemic family therapy (SyFT), to understand which aspects of these treatment approaches are helpful versus hindering to recovery from an eating disorder (ED). Parental involvement was crucial in facilitating the restoration of physical health through the process of parents taking temporary responsibility for the young person's eating behaviours until they can feed themselves again. However, treatment often failed to acknowledge and address the psychological and emotional difficulties that made the young person vulnerable to developing AN, as well as the psychological distress caused by increasing food-intake and weight. A positive therapeutic relationship in which families felt well supported by their therapist was important in providing containment during a time of familial strain and instability, yet there was a need for greater flexibility and individualisation within manualised ED-focussed family therapy approaches, particularly FBT. The findings highlight the importance of eliciting the young person's voice to enhance their personal agency in treatment and the value of therapeutic space to improve family functioning and enhance family unity. Lastly, they illuminate the need for manualised ED-focussed family therapy models to allow space for the therapist to emotionally attune to young people and families in order to contain their experience of distress.
