Psychometric analysis of the Emotional Availability Scales

Abstract

In the context of parent-child interaction, the Emotional Availability Scales (EAS; 4th ed.; Biringen, 2008) have been developed to capture a dyad’s emotional connection in observational settings by four parental and two child-related scales. This study aims to test the psychometric foundation of the EAS for a preschool-aged sample and complements analyses by Aran et al. (2022) for a sample of infants. The sample of parents and their preschool-aged children is a mixed clinically referred and non-clinical sample from a mid-sized city in Germany. Interactions were observed in a free-play setting and rated with the EAS by two blind and certificated raters. Several model tests indicate violations for the structural model as well as all six measurement models. An additional post hoc exploratory factor analysis with parallel analysis suggests a non-interpretable two-factor-structure. Psychometric analyses did not validate the EAS’ postulated structure and measurement model. A post hoc literature review showed that ceiling effects on the item and scale levels are not unique to our study. However traditional important concepts or terms of parent-child relationships covered by the EAS are not rejected by our study and can be assessed with alternative measures, but these also need psychometric evaluation in the future.
