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.

二元亲子互动编码系统（DPICS）：析因结构和并行有效性。

背景技术“儿童保护服务”中的综合家庭评估应包括具有适当心理计量学特征的工具。本研究旨在提供二进位亲子互动编码系统（DPICS）的阶乘结构和其他心理计量特性的初步证据。方法参加者为80例4至8岁儿童的母二倍体，他们获得了西班牙儿童保护服务局的家庭支持。结果验证性因素分析显示非常适合包含15个项目的四因素解决方案（赞美，问题，清晰的命令和负面谈话）。评价者间的可靠性指标是最佳的。并发有效性的证据表明，DPICS因素与自我报告的育儿和老师告知的儿童行为问题有关。结论本研究为DPICS评估儿童保护服务中母婴互动的心理计量学特性提供了初步证据。仍然需要对母子和父子二元组的更大样本进行进一步的研究，以确认四因素解决方案。
