Dyadic Parent-Child Interaction Coding System (DPICS): Factorial Structure and Concurrent Validity.

Abstract

BACKGROUND\nComprehensive family assessments in Child Protection Services should include instruments with suitable psychometric characteristics. The present study aims to provide initial evidence of the factorial structure and other psychometric properties of the Dyadic Parent-Child Interaction Coding System (DPICS).\n\n\nMETHOD\nParticipants were 80 mother-child dyads with children aged 4-8 who received family support from Child Protection Services in Spain.\n\n\nRESULTS\nConfirmatory factor analysis showed good fit for a four-factor solution (Praise, Questions, Clear commands and Negative talk) with 15 items. Inter-rater reliability indices were optimal. Evidence of concurrent validity found that DPICS factors were related to self-reported parenting and teacher-informed child behavior problems.\n\n\nCONCLUSIONS\nThis study provides preliminary evidence of the DPICS’s psychometric properties for assessing mother-child interaction within Child Protection Services. Further research with larger samples of mother-child and father-child dyads is still needed to confirm the four-factor solution.
