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).
Participants were 80 mother-child dyads with children aged 4-8 who received family support from Child Protection Services in Spain.
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.
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.
儿童保护服务中的综合家庭评估应包括具有适当心理测量特性的工具。本研究旨在提供 Dyadic Parent-Child Interaction Coding System（DPICS）的因子结构和其他心理测量特性的初步证据。
参与者为 80 对来自西班牙儿童保护服务的 4-8 岁接受家庭支持的母子对。
验证性因素分析显示，具有 15 个项目的四因子解决方案（表扬、问题、明确指令和负面谈话）具有良好的拟合度。评分者间信度指数为最优。同时效度的证据表明，DPICS 因子与自我报告的养育方式和教师报告的儿童行为问题有关。
本研究为 DPICS 在儿童保护服务中评估母子互动提供了初步的心理测量特性证据。仍需要对更大的母子和父子对子样本进行进一步研究，以确认四因子解决方案。
