Intentions : « This study examines an earlier investigtion on the link between familial traits and eating disorders (EDs), and examines the extent to which selected eating attitudes and psychopathological traits are: a) familial in nature and b) specific to anorexia- and bulimia- spectrum disorders. » (p. 147)
Échantillon/Matériau : « We measured various ED-relevant dimensions (eating and body image attitudes) and psychopathological traits (e.g., affective instability, narcissism, compulsivity, restricted expression) in the mothers, fathers and sisters of probands displaying an ED (n=88), another psychiatric disturbance (n=42), or neither disturbance (n=59) total sample including relatives, was 553. » (p. 148)
Instruments : - Body Dissatisfaction Scale (BDS); - Eating Attitudes Test (EAT-26); - The Dutch Eating Behavior Questionnaire (DEBQ); - ED Screening.
Type de traitement des données : Analyse statistique
« The eating disorders (EDs) anorexia and bulimia nervosa appear to be unusually common among the female relatives of anorexic (Strober, Lampert, Morrell, Burroughs, + Jacobs, 1990) and bulimic (Kasset, Gershon, Maxwell. et al., 1989) probands, and therefore seem to be familial syndromes. However, various processes could explain familial patterns, including genetic effects, shared environmental influences, inheritance of psychological traits associated with risk, and psychological induction effects (Strober et al. 1990). [...] The present study further explored familial tendencies on eating attitudes and psychopathological traits, addressing certain uncertainties surrounding apparently contradictory findings in the literature [...] Such apparent contradictory findings give rise to various questions around the extent to which eating attitudes and psychological traits are familial, and moreover, the extent to which they are causal in anorexia- and bulimia-spectrum disorders). » (p. 148)
