Table 4 PIR-GAS ratings from two raters (1,2) on the basis of a 10-minute mother-child-interaction video compared to a group rating on basis of full clinical information at admission and discharge and supplementary Pearson correlations for interrater reliability and to external criteria (CBCL1.5-5; SCL-90-R GSI)

From: Inter-rater reliability and aspects of validity of the parent-infant relationship global assessment scale (PIR-GAS)
