Translation and Psychometric Validation of the Indonesian Version of the Online Histrionic Personality Scale (OHPS) Among Indonesian Social Media Users

The research aims to translate and validate the Indonesian version of the Online Histrionic Personality Scale. Using a quantitative design, data were collected from 838 active social media users using purposive sampling. Rasch analysis was used to evaluate item functioning; CFA was used to examine the factor structure. Structural Equation Modeling (SEM) was performed to establish nomological validity by testing the structural relationships between online histrionic traits, social approval motives, and problematic social media use. Rasch analysis showed strong item reliability, person reliability, and confirmed unidimensionality (72.2% variance explained). CFA showed that the one-factor model has good model fit (CFI = 0.988, RMSEA = 0.076) and strong factor loadings (0.85–0.95). High correlation with related histrionic measures (r > 0.90) established convergent validity. This study provides the first cultural adaptation and psychometric evaluation of the Online Histrionic Personality Scale in Indonesia. OHPS showed high reliability and validity and can be used in Indonesia as a promising instrument for measuring the histrionic personality trait in online users.
