This paper presents the psychometric properties of a French adaptation of the Coding Interactive Behavior (CIB), a scale developed by Ruth Feldman and largely used to study mother-infant interaction.
The original manual has been translated in French and adapted to French terminology of concepts. Then Ruth Feldman controlled the translation with the help of a bilingual psychologist. The scale was administered to 74聽clinical and non-clinical dyads recruited in an obstetric clinic, at birth and 2聽months postpartum. Confirmatory factor analyses were employed to assess factorial structure using Cronbach's alpha. Inter-rater reliability was estimated with Interclass Correlation Coefficients (ICC).
Inter-rater reliability of the training was good with a median ICC equal to 0.88. Confirmatory factor analyses supported a comparable latent factor structure as reported in the original CIB with 伪 ranging from 0.67聽to 0.96聽at birth and 0.63聽to 0.95聽at 2聽months. Inter-rater reliabilities at birth and 2聽months were good with ICC ranging from 0.85聽to 1聽for each item.
The results indicate that the French version of CIB shares the same latent factor structure as its original counterpart and is a useful tool to assess early mother-infant interaction.
