Coparenting interactions observed by the prenatal lausanne trilogue play: An Italian replication study

The infant–parent interaction is the focus of interest on early interactive relational models in the triadic perspective. This approach considers the mother–father–child interaction as the matrix of early competences, which start to develop well before delivery. This theoretical approach has generated an observation paradigm, the Lausanne Trilogue Play (LTP; E. Fivaz‐Depeursinge & A. Corboz‐Warnery, 1999). The aim of the study was to investigate (a) the psychometric characteristics of coding of the prenatal LTP procedure and their comparison with the Lausanne validation studies and (b) the characteristics of triadic interactions during pregnancy. Ninety‐eight nonreferred, primiparous families were recruited at childbirth courses. In addition to validated questionnaires, observational data were collected at the seventh month of pregnancy in the prenatal LTP. The collected data show good reliability of the LTP coding and a consistent factorial structure in line with the Lausanne validation studies (C. Carneiro, A. Corboz‐Warnery, & E. Fivaz‐Depeursinge, 2006; N. Favez et al., 2006). The Structure of the Play and the Intuitive Parenting Behaviors Scales seem the most representative dimensions in the prenatal period. Coparental abilities during pregnancy represent an interactive matrix for the construction of early family relations and may be considered as protective factors in the child's development of early triadic interactive abilities.
