Abstract

This study introduces distinct types of validity and reliability evidence of the Authenticity Scale (AS) in a sample from Brazil and Portugal. It consists of an online survey with 1,077 Brazilian citizens and 622 Portuguese citizens. The study tested the model with three correlated factors (self-alienation, authentic living, and accepting external influence), the unidimensional model, and the bi-factor model. The model with three correlated factors was retained, with the three subscales demonstrating moderate to good reliability. Multigroup confirmatory factor analysis suggested scalar invariance across culture, gender, age, education, occupation, and Covid-related concern and impact. The items were assessed by graded response model (GRM), which suggested that the three subscales are not able to distinguish respondents with high authenticity traits. GRM and descriptive statistics indicated that the rating-scale is inappropriate, particularly for authentic living subscale, which is affected by ceiling effect. Associations with presence of meaning showed additional validity evidence. Despite the limitations, the AS is an effective measure to assess authenticity across different groups. Potential modifications for the improvement of the AS are discussed.
