Development, Rasch Validation, and Confirmatory Factor Analysis of the Individual's Social Responsibility Scale

Background: This study aimed to systematically develop and validate a measurement instrument for individual’s social responsibility (ISRS). It seeks to ensure robust psychometric properties and construct validity through Rasch model and confirmatory factor analysis (CFA). Methods: This study employed a cross-sectional design and collected questionnaire responses from 812 individuals in Saudi Arabia through a random sample. The study collected data using demographic variables and the Arabic-language ISRS (16-items), developed and validated through Rasch analysis and CFA using the Wisntep (version 5.3.2) and AMOS (version 23) software, respectively. The CFA results demonstrated a good fit for the model, with indices such as RMSEA (0.067) falling within the recommended range and CFI score of 0.96, exceeding the threshold of >0.95. Rasch analysis confirmed the reliability of the ISRS items and subscales, with adjustments made to the Likert scale for enhanced precision, based on the results of ISRS1, ISRS4-8, ISRS14, and ISRS16. Multidimensionality assessments revealed significant variations in explained variances, with participant hierarchy analyses supporting efficient test item targeting. This study emphasizes the significance of community engagement, personal commitment, and social concern in fostering individual social responsibility among Saudi Arabian individuals, providing valuable insights for future research and interventions aimed at promoting social responsibility in the region.
