Contingency in maternal sensitivity and quality of child attachment.

Patterns of maternal contingent responses to their eight-month-old infants were studied across three groups based on the attachment style that children developed at 15 months, assessed with the SSP: Insecure-Avoidant, Secure or Insecure-Resistant. The participants were 78 mother-infant dyads who interacted in a free play setting. The interactions were assessed using CITMI-R, an observational system that allows real time coding. Two dimensions of maternal sensitivity, 'appropriateness' and 'promptness' were analysed from the perspective of the infant. Appropriateness in terms of proportion of different maternal responses, interfering and not interfering (qualitative profile) and the frequency of them (quantitative), and promptness as the latency of the contingent responses. Results showed that infants in the secure attachment group received a lower proportion of interfering behaviors when interacting with their mothers than their insecure attached counterparts. They also experienced higher frequency of non-interfering maternal contingent responses and quicker, protective-intrusive responses. Therefore, the secure attachment group of children experienced less interruption and more attentive responses from their mothers
