Abstrak
This study aims to construct a shyness scale based on Henderson and Zimbardo's (1998) theory, which includes four dimensions: cognitive, emotional, physiological, and behavioral. The construction process involved identifying test objectives, determining the behaviors to be measured, preparing test specifications, constructing items, expert reviews, pilot testing, and psychometric analysis to ensure validity and reliability. A total of 254 participants aged 15–25 years (M=19, SD=2.16) from various regions in Indonesia participated in this study. The results showed that the scale model had an RMSEA value of 0.044, a CFI of 0.98, and an SRMR of 0.061. All items had factor loadings ≥ 0.3 with t-values ≥ 1.96, except for one item retained due to its statistical significance and theoretical relevance. The reliability coefficient, measured by Cronbach’s Alpha, was 0.922, indicating very high internal consistency. Item discrimination analysis revealed that most items had good discriminative power, although some items require revision to improve their performance. The implications of this study include the development of a culturally relevant measurement tool for Indonesia and its application in psychological research and interventions. Future research is recommended to include a more diverse sample to enhance the generalizability of the scale.
