There are many measures designed to capture the quality of parent-child interaction based on varying theories and forms of responses or observation. However, there is limited evidence to compare the constructs existing in between these measures when applying in children with developmental delay. We conducted a systematic review for synthesizing relevant measures. The Nursing Child Assessment Teaching Scale (NCATS), the Maternal Behavior Rating Scale (MBRS), and the Children Behavior Rating Scale (CBRS) were found to be three frequently used measures in Taiwan with sound psychometric property. The reliability was examined and was acceptable for the three measures. The convergent and discriminant validity between the NCATS and MBRS/CBRS were tested with Pearson correlation among the measurement dimensions/subscales using the videotapes for scoring the NCATS in previous study. The findings show moderate but significant correlations (r= .462-.504, p&;lt;0.05) between one of the MBRS scales (Responsive/Child Oriented), and 3 of the NCATS caregiver subscales (Sensitivity to Cues, Response to Distress and Caregiver Contingency), while no significant correlations between NCATS child subscales and the CBRS. The significant correlations between measure dimensions/subscales indicate the convergent validity (i.e. similar construct) between measurable concepts, while no correlations between measure dimensions/subscales indicate discriminant validity (i.e. different constructs) between measurable concepts. In this study, convergent validity was found between MBRS scales and the NCATS caregiver subscales on the scales related to mother’s responses to children, and discriminant validity were found between all NCATS subscales and the subscales of Achievement orientation and Directive of MBRS. The lacking of correlations between NCATS child subscales and the CBRS further support the fact that the two measures capture different aspects of parent-child interaction on children’s responses. Hence using multiple measures to comprehensively explore interactional behavior for parents and children based on the purposes of measuring parent-child interaction were suggested.
