Very extensive nonmaternal care predicts mother–infant attachment disorganization: Convergent evidence from two samples / Nancy L. HAZEN in Development and Psychopathology, 27-3 (August 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-3 (August 2015) . - p.649-661 Titre : Very extensive nonmaternal care predicts mother–infant attachment disorganization: Convergent evidence from two samples Type de document : Texte imprimé et/ou numérique Auteurs : Nancy L. HAZEN, Auteur ; Sydnye D. ALLEN, Auteur ; Caroline HEATON CHRISTOPHER, Auteur ; Tomotaka UMEMURA, Auteur ; Deborah B. JACOBVITZ, Auteur Article en page(s) : p.649-661 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We examined whether a maximum threshold of time spent in nonmaternal care exists, beyond which infants have an increased risk of forming a disorganized infant–mother attachment. The hours per week infants spent in nonmaternal care at 7–8 months were examined as a continuous measure and as a dichotomous threshold (over 40, 50 and 60 hr/week) to predict infant disorganization at 12–15 months. Two different samples (Austin and NICHD) were used to replicate findings and control for critical covariates: mothers' unresolved status and frightening behavior (assessed in the Austin sample, N = 125), quality of nonmaternal caregiving (assessed in the NICHD sample, N = 1,135), and family income and infant temperament (assessed in both samples). Only very extensive hours of nonmaternal care (over 60 hr/week) and mothers' frightening behavior independently predicted attachment disorganization. A polynomial logistic regression performed on the larger NICHD sample indicated that the risk of disorganized attachment exponentially increased after exceeding 60 hr/week. In addition, very extensive hours of nonmaternal care only predicted attachment disorganization after age 6 months (not prior). Findings suggest that during a sensitive period of attachment formation, infants who spend more than 60 hr/week in nonmaternal care may be at an increased risk of forming a disorganized attachment.
