Clinical Validation of the Caregiver-Child Socioemotional and Relationship Rating Scale (SIRS) for Child Behavior in a Preschool-Age Sample

The description of child behavior in mother-child-interaction is important in early detection and treatment of psychiatric disorders in preschool children. The Caregiver-Child Socioemotional and Relationship Rating Scale (SIRS) may serve this diagnostic purpose. We aim to examine interrater-reliability of SIRS and concurrent, convergent, and discriminant validity to maternal behavior by Play-PAB, and a measure of mother-child-relationsship by Parent-Infant-Global-Assessment-Scale (PIRGAS). Five raters assessed 47 ten-minute video sequences of parent-child-interaction recorded at the Family Day Hospital for Preschool Children with SIRS, Play-PAB, and PIRGAS. We report psychometric properties of SIRS, and present the association with Play-PAB and PIRGAS. SIRS shows a satisfying interrater-reliability for all items. Positive child behavior e.g. the SIRS' "child responsiveness" shows negative correlation to Play-PAB-scales' parental "hostility" and "intrusiveness", but independence of parental, involvement", "positive emotionality", and "discipline". Child and parental behavior show expected associations with the global relationship measure PIRGAS. The assessment of child behavior in parent-child-interaction with SIRS can be quickly learned and reliably applied without extensive training. SIRS shows meaningful relations to parental behavior and a clinical global measure of the caregiver-child-relationship. We recommend SIRS for clinical diagnostics to describe child behavior in mother-child-interaction.
