A new coding system: The Neuropsychomotor Video Analysis of parent and child interaction (NVA)

pdf

The study investigated the validity of a Neuropsychomotor Video Analysis of parent and child interaction (NVA), a new observational coding system for parent-child interactions. 73 mother-infant interactions were video-recorded and codified with NVA and with Care-Index to verify the instrument validity. Convergent validity was supported by significantly positive correlations between the NVA and the Care-Index categories. Moreover, analysis indicated correlations between NVA mother’s codes and NVA infant’s codes. These results suggest that the NVA has the potential to be a valuable rating system for assessing parent–child relationships.
