Journal of Abnormal Psychology, vol. 105, no 4, p. 500-507.
Intentions : « We wanted to determine whether mothers’ childhood social behavior (i.e., aggressive, withdrawn, or both) would add a risk factor for offsprings’ injuries and acute illness beyond their previously established risk as children of adolescent mothers. » (p. 501)
Échantillon/Matériau : « Ninety-four women [...] gave birth to their first child before their 21st birthday. The age of these women at the birth of their first child averaged 18.95 years [...]. » (p. 502)
Instruments : « [...] computer tape from Quebec’s universal Medicare service (Régie de l’Assurance-Maladie du Québec) » and include all medical record of the 94 first born children through December 1993. »
Type de traitement des données : Analyse statistique
« In a 15 year longitudinal study, the medical records of 94 children whose adolescent mothers had childhood histories of aggressive, withdrawn, aggressive-withdrawn, or normative (nondeviant) social behavior were examined. The children’s annual rates of visits to the emergency room (ER) and to nonemergency medical facilities, postER hospitalizations, diagnoses of injuries, acute illness and infection, asthma, and emergency surgical consultations were examined between birth and 48 months of age. Group differences were found for the annual rate at which children were brought to the ER and for injuryrelated postER hospitalizations. Sons of women in the aggressive group and both sons and daughters of women in the aggressive-withdrawn group had elevated and distinctive profiles in respect to specific emergency diagnostic and treatment variables compared with children of women in the nondeviant group. » (p. 500)
