Intentions : « The purpose of the present study is to examine issues by using home observations-based measures of attachment in disabled and non-diseabled infants. » (p. 150) Questions/Hypothèses : « 1) As with strange situation findings, we expect to find that proportions of secure, avoidant and ambivalent home classifications are similar in groups of physically disabled infants. 2) We expect to replicate the Morgan et al. (1992) results and obtain an overall lower AQS security score for disabled infants when compared to their non-disabled counterparts. » (p. 151)
Échantillon/Matériau : 34 enfants caucasiens, Canadiens-Français et leur mère ayant une déficience physique. Le groupe de comparaison est composé de 26 enfants caucasiens, Canadiens-Français sans déficience physique et leur mère. Les enfants étaient âgés de 15 à 24 mois au moment de l’étude.
Instruments : - Harvey Developmental Scales (Harvey, 1984); - Bayley Developmental Scales (Bayley, 1993); - Attachment Behavior Q-set ( Waters, 1986); - Attachment Home Classifications (Pederson & Morgan, 1995, 1996). Type de traitement des données : Analyse statistique
« This study investigated attachment security and behavior in 34 physically disabled infants and 26 non-disabled infants by using convergent, categorical (secure, avoidant and ambivalent) and continuous (Attachment Behavior Q-Set; AQS) measures of the relationship, based on the same set of home observations. Proportions of attachment classifications were not different for disabled and non-disabled infants, but insecure infants in the disabled group scored consistently lower on the AQS security score than non-disabled insecure infants. This result suggests that while proportions of attachment classifications may not vary as a function of infant status, insecure disabled infants are more insecure than insecure non-disabled infants. An analysis of 5 behavioral dimensions of the AQS showed that secure infants emitted the same kinds of attachment behaviors without regard for infant status. Insecure disabled infants, however, showed lower levels of secure base behavior and physical contact with mother than their non-disabled counterparts, and showed a marginal tendency to fuss more as well. Discussion focuses on the potential benefits of using convergent, categorical and continuous measures of attachment in the study of both typical and atypical groups of infants. » (p. 147)
