Topic: Considerations for Measurement in Parent-Child Interactions including Children with Down Syndrome
Children with Down syndrome (DS) demonstrate significant deficits in language abilities beginning early in life. Parent input plays an important role in supporting language development for young children with DS. Previous research has approached the investigation of parent input and child communication during parent-child interactions through multiple avenues. Approaches to examining early interactions include the use of automated measures from recordings without an examiner present as well as manual coding of interactions with an examiner present. Limited research has investigated how these two methods of measurement compare, which is particularly important given that manual coding is time-intensive and automated measures may provide a valid alternative. Study 1a compared these two methods in families of mothers, fathers, and their children with DS. Some aspects of automated measures were related to manually coded parent-child interactions. Study 1b examined another aspect of measurement in parent-child interactions: maternal vs. paternal input. The majority of work has focused on maternal input, yet it is unclear if findings can be generalized to fathers. Comparisons of mothers and fathers from the same families from study 1a resulted in findings of both overlap and differences in the total amount and lexical quality of maternal and paternal input.
