Factorial Invariance and Norming of the Overexcitabilities Scales

Abstract This study aimed to establish preliminary norms and verify the structure and factorial invariance of the Overexcitabilities Scales (OS) according to sex. It is a measure for the assessment of overexcitability - tendency to react intensely and sensitively to stimuli in Sensual, Psychomotor, Imaginative, Emotional, and Intellectual areas. Participants included 1500 elementary school students from five Brazilian states. Confirmatory factor analysis demonstrated good adjustment indices for the tested models, revealing the existence of 11 scales. Although there were differences regarding sex in the mean scores of some scales, confirmatory multigroup factor analysis indicated the factorial invariance of the measure in male and female groups. The preliminary norms were established by calculating the cumulative percentile for the total scores and sex. These results show adequate psychometric properties and represent progress for OES norming.

摘要 本研究旨在建立过度兴奋性量表（Overexcitabilities Scales, OS）的初步常模，并验证该量表按性别划分的结构与因子不变性。该量表用于评估过度兴奋性，即个体在感官、精神运动、想象、情绪及智力领域对刺激产生强烈且敏感反应的倾向。研究纳入来自巴西5个州的1500名小学生作为被试。验证性因子分析结果显示，所测试模型的拟合指数良好，表明该量表包含11个分量表。尽管部分分量表的平均得分存在性别差异，但多组验证性因子分析表明，该量表在男性与女性群体中均具有因子不变性。本研究通过计算总分及分性别的累积百分位数，建立了该量表的初步常模。上述结果表明该量表具备良好的心理测量学属性，为过度兴奋性量表（OES）的常模制定工作取得了进展。
