Background: Comprehensive 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). Method: Participants were 80 mother-child dyads with children aged 4-8 who received family support from Child Protection Services in Spain. Results: Confirmatory 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. Conclusions: This 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.

Dyadic Parent-Child Interaction Coding System (DPICS): Estructura Factorial y Validez Concurrente. Antecedentes: la evaluación de familias en los Servicios de Protección Infantil debería incluir instrumentos con características psicométricas adecuadas. El objetivo principal de este estudio es proporcionar evidencia de la estructura factorial y otras propiedades psicométricas del Dyadic Parent-Child Interaction Coding System  (DPICS). Método: la muestra estuvo formada por 80 díadas madre-hijo/a con niños/as de 4 a 8 años que recibieron servicios de apoyo familiar de los Servicios de Protección Infantil en España. Resultados: el análisis factorial confirmatorio mostró un buen ajuste para la estructura de cuatro factores (Elogio, Pregunta, Orden Clara y Verbalización Negativa) con 15 ítems. Los índices de fiabilidad interjueces fueron adecuados. Las evidencias de validez concurrente mostraron que los factores del DPICS estaban relacionados con las competencias parentales autoinformadas y con los problemas de conducta infantil informados por los profesores. Conclusiones: el presente estudio proporciona evidencia preliminar sobre las propiedades psicométricas del DPICS para la evaluación de la interacción madre-hijo/a en los Servicios de Protección Infantil. Sería necesario continuar investigando con muestras más amplias de díadas madre-hijo/a, así como díadas padre-hijo/a para confirmar la estructura de cuatro factores.
