Relation between increasing attachment security and weight gain: a clinical study of adolescents and their parents at an outpatient ward

PURPOSE: We wanted to evaluate the impact of a relational focus in the treatment of adolescent ED-patients and their parents at an intensive outpatient ward, based on attachment theory, combined with a family approach and psychodynamic principles. Our aim was to investigate the distribution of different attachment styles among the adolescent ED-patients and their parents, and to find out if they could change by the treatment. METHODS: Swedish adolescents (n = 33; 3 boys, 30 girls) and their parents (n = 60; 34 mothers, 26 fathers) participated. Measures: Attachment Style Questionnaire (ASQ), Body Mass Index (BMI) and Children’s Global Assessment Scale (CGAS) before and after treatment. RESULTS: The adolescents were high on Need for Approval (ASQ4) of the Insecure/Anxious scale before treatment (in contrast to the parents). The patients had a significant decrease in ASQ4 after treatment, which correlated inversely to the increase in BMI but not to CGAS. The mothers showed features of the Secure/Confident style, fathers of the Insecure/Avoidant with elevated Relationships as Secondary (ASQ2). CONCLUSIONS: Treatment with a relational and a family focus has impact on attachment insecurity in adolescent ED-patients and outcomes in terms of BMI. It is important to engage the parents, who need to help the adolescents to separate at that developmental stage. A secure therapeutic context, which enables mentalizations and allows new relational experiences, is essential. The ASQ-instrument is useful in indicating how the treatment of ED-adolescents is proceeding. LEVEL OF EVIDENCE: Level IV: evidence obtained from multiple time series with the intervention.
