Comparing Psychometric Indicators of Two Brazilian Versions of the Social Skills Rating System: A Literature Review

Abstract The Social Skills Rating System is one of the most frequently cited measures in the literature to assess social skills of children, with quite satisfactory reliability and validity properties in several countries. The Brazilian version of the instrument was subjected to validation processes at two different times, using two methods of Factor Analysis: Principal Components (SSRS-BR, 2009) and Principal Axis Factoring (PAF) with subsequent Confirmatory Factor Analysis (SSRS-BR2, 2015). The purpose of this article is to compare the psychometric indicators of the two Brazilian versions of these scales, presenting their differences and similarities in terms of: (a) extraction methods and data analysis, (b) psychometric indices of factor structure and reliability and (c) final factorial composition and content of the scales. Possible psychometric refinements arising from the SSRS-BR2 are discussed, as well as its implications for evaluation procedures of social skills in children.

摘要 社会技能评定量表（Social Skills Rating System，SSRS）是当前学界评估儿童社会技能时引用最为频繁的测评工具之一，在多个国家均具备良好的信度与效度属性。该量表的巴西本土化版本曾分两个阶段开展验证工作，分别采用两种因素分析方法：2009年版（SSRS-BR）采用主成分分析（Principal Components），2015年版（SSRS-BR2）则采用主轴因素分析（Principal Axis Factoring，PAF）结合后续验证性因素分析（Confirmatory Factor Analysis）的研究方案。本文旨在对比这两套巴西版量表的心理测量学指标，从以下三方面阐述二者的异同：（a）因素提取方法与数据分析流程，（b）因素结构与信度的心理测量学指数，以及（c）量表最终的因素构成与内容。本文还探讨了SSRS-BR2版本可能存在的心理测量学优化方向，及其对儿童社会技能评估流程的实践意义。
