Psychometric parameters of the subscale of hostility from the Symptom Checklist 90 (SCL-90)

Abstract The present study aimed to know the psychometric parameters of the SCL-90 hostility scale. For this, two studies were traced; In Study 1, 209 students, mean age 16 years (SD = 1.29), who responded to the Scale of Hostility and a sociodemographic questionnaire. The exploratory factorial analysis indicated a unidimensional structure, whose Cronbach’s alpha was.71. In Study 2, we sought to find additional evidence of validity and reliability counting with 212 students with a mean age of 16 years (SD = 1.19). The confirmatory factorial analysis tested the unifactorial structure and pointed to good adjustment indexes; good internal consistency and composite reliability were also observed. In general, the Scale of Hostility provided evidence of satisfactory validity and reliability.摘要 本研究旨在明确SCL-90敌对量表（SCL-90 Hostility Scale）的心理测量学属性。为此开展了两项子研究：研究1纳入209名平均年龄为16岁（标准差SD=1.29）的学生，要求其完成敌对量表与社会人口学问卷。探索性因素分析结果显示该量表具备单维结构，其克朗巴赫α系数为0.71。研究2招募了212名平均年龄为16岁（SD=1.19）的学生，旨在进一步验证该量表的效度与信度。验证性因素分析检验了该单因素结构，结果显示其拟合指标良好；同时观测到良好的内部一致性与合成信度。总体而言，该敌对量表的效度与信度均提供了令人满意的实证证据。
