Parent and child report of family functioning in a clinical child and adolescent eating disorders sample.
OBJECTIVE
To investigate parent and self-report of family dysfunction in children and adolescents with eating disorders. Further, to investigate family functioning differences across the eating disorders diagnostic groups; anorexia nervosa, eating disorders not otherwise specified (EDNOS) and bulimia nervosa, and between the restricting and binge-purge eating disorders behavioural subtypes.


METHODS
The Family Adjustment Device General Functioning Scale (FAD-GFS) was administered to 100 children and their parents who presented consecutively at an eating disorders assessment clinic. DSM-IV eating disorders diagnoses in this group included 42 children diagnosed with anorexia nervosa, 26 with EDNOS, 12 with bulimia nervosa and 20 diagnosed as having no eating disorder.


RESULTS
Both the parent and child FAD-GFS report demonstrated high internal consistency supporting the suitability of this instrument for research with this sample. Parent and child reports were moderately positively correlated. Total scores for all eating disorders diagnostic categories were significantly higher than community norms. Anorexia nervosa, EDNOS and bulimia nervosa groups did not significantly differ on parent or child reports. FAD-GFS profiles for restricters and binge-purgers suggest higher levels of family dysfunction in the families of binge purgers.


CONCLUSIONS
The FAD-GFS has suitable psychometric properties for use as a summary instrument with young people diagnosed with an eating disorder. However, more informative instruments assaying a greater range of constructs, especially in the impulsive, dyscontrol domain, are required to investigate differences among eating disorders diagnostic groups and behavioural subtypes.
