The Iowa-Netherlands Comparison Orientation Measure (INCOM) was developed to measure individual differences in social comparison orientation and has been widely used in research and various different settings.
The aim of this study was to adapt the online version of the INCOM and to evaluate its psychometric parameters when applied to a Brazilian population of university students.
The procedures were divided into two steps: step 1 - cross-cultural adaptation and analysis of content validity, and step 2 - assessment of psychometric characteristics. Step 1 comprised the processes of translation, evaluation by an expert committee, evaluation by the target population, and back-translation. For step 2, 1,065 university students were recruited and then factor analysis, analysis of reliability, and analysis of validity based on external measures were performed.
The adaptation process yielded satisfactory results, including good indicators of content validity. Exploratory factor analysis revealed a two-dimensional structure and adequate factor loadings, except for item 11, which was excluded from the final version. Additionally, the final version of the scale had adequate fit indices (χ2 = 148.45, degrees of freedom [df] = 26; p < 0.001; root mean square error of approximation [RMSEA] = 0.06; comparative fit index [CFI] = 0.99; and Tucker-Lewis index [TLI] = 0.98). Evidence of reliability (Cronbach's alpha = 0.83) was observed and there were positive correlations with negative affect (r = 0.36) and negative correlations with positive affect and self-esteem (r = -0.15; r = -0.41, respectively).
The Brazilian version of the INCOM presents satisfactory psychometric parameters and can thus be used to measure social comparison orientation.
爱荷华-荷兰比较取向量表（INCOM）旨在衡量社会比较取向的个体差异，已广泛应用于研究和各种不同的环境中。
本研究旨在改编 INCOM 的在线版本，并评估其在应用于巴西大学生群体时的心理计量学参数。
该程序分为两个步骤：第 1 步 - 跨文化适应和内容效度分析，第 2 步 - 评估心理计量学特征。第 1 步包括翻译、专家委员会评估、目标人群评估和回译过程。对于第 2 步，招募了 1065 名大学生，然后进行了因子分析、可靠性分析和基于外部测量的有效性分析。
适应过程产生了令人满意的结果，包括内容效度的良好指标。探索性因子分析显示出二维结构和足够的因子负荷，除了第 11 项，它被排除在最终版本之外。此外，该量表的最终版本具有适当的拟合指数（χ2=148.45，自由度[df]=26；p<0.001；近似均方根误差[RMSEA]=0.06；比较拟合指数[CFI]=0.99；和 Tucker-Lewis 指数[TLI]=0.98）。观察到可靠性的证据（Cronbach's alpha=0.83），并且与负性情绪（r=0.36）呈正相关，与正性情绪和自尊（r=-0.15；r=-0.41）呈负相关。
巴西版的 INCOM 具有令人满意的心理计量学参数，因此可用于测量社会比较取向。
