Abstract
Introduction
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 different contexts. 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.
Methods
The procedures were divided into two steps: step 1 – cross-cultural adaptation and content validity, and step 2 – assessment of psychometric characteristics. In step 1, the processes of translation, evaluation by expert committee, evaluation by the target population, and the back-translation, were performed. In step 2, 1065 university students participated and factor analysis, analysis of reliability and validity based on external measures were performed.
Results
The adaptation process showed satisfactory results, such as good indicators of content validity. Exploratory factor analysis indicated a two-dimensional structure and adequate factor loadings, except for item 11, which was excluded from the final version. Also, the final version of the scale presented adequate fit indices (χ2 = 148.45, df = 26; p < 0.001; RMSEA = 0.06; CFI = 0.99; TLI = 0.98). Evidence of reliability (Cronbach's alpha = 0.83) was found, in addition to positive correlations with negative affect (r =0.36) and negative correlations with positive affect and self-esteem (r = -0.15; r = -0.41, respectively).
Conclusion
The Brazilian version of the INCOM presents satisfactory psychometric parameters and can thus be used to measure social comparison orientation.
