Aspects of the eco-systemic approach were used to provide a framework for the understanding of anorexia nervosa and were empirically tested by comparing 30 anorexics and their parents to 34 matched control subjects and their parents. The theoretical model employed was an adaptation of Conger's Ecological-Systems approach which was based on the principles of Bronfenbrenner's theory of human development. The subjects were compared on selected variables arising from the individual, parent, family, and community systems using (a) the California Psychological Inventory (CPI), (b) the Structural Analysis of Social Behavior (SASB), (c) the Family Environment Scale (FES), and (d) the Pattison Psychological Inventory (PPI). Discriminant analysis revealed that the Affiliation score (SASB) for the anorexic and the control subjects and the Psychopathic Deviancy score (CPI-Clinical) of the mothers of the anorexics and the controls were the variables which contributed most to the discrimination between the groups. With the Affiliation and the Psychopathic Deviancy scores alone, it was possible to correctly classify 87.5 per cent of the research subjects. Analyses also showed statistically significant results at the individual, parent, and family levels. Interactions within the family, as perceived by the anorexics, were characterized by overprotection and control by the mothers, while the anorexics themselves responded with significantly less affiliation to both their mothers and their fathers. The mothers of the anorexics also viewed their daughters as being less friendly in the relationship. The families of the anorexics were less supportive, helpful, and committed to each other than were the families of the control subjects as measured by the FES.
