Observation of parent-child interaction with two- to three-year-olds.

A method of home observations of mother-child interaction is described. Its development is outlined in terms of the relevant conceptual and methodological issues, and the concomitant tactical decisions involved in development are discussed. The scheme focuses on parental responsivity, affect, social communication and social control, and a novel combination of time-interval and event-sequential recording is used to discriminate parental functioning in these areas. The measures have been shown to have a satisfactorily high level of reliability, and preliminary analysis indicates construct validity.
