Scientific research in humanities, education, and social sciences often depends on tools like scales, tests, and questionnaires. These tools are essential for data collection and are also widely used in practical applications, such as employment decisions, diagnosis, and screening in educational settings. However, researchers frequently encounter challenges when collecting data, especially with complex constructs and numerous variables. The growing demand for efficient data collection tools has underscored the importance of short-form scales. Lengthy instruments can compromise the validity of responses, particularly in clinical or diagnostic settings where multiple tools are needed, leading to a trade-off between test reliability and administration time.
This study aims to compare practices in developing short forms of scales in Arab and non-Arab contexts and to examine how procedural differences affect the validity of results. The sample included 9 Arab studies from Shaal and Dar Al Mandumah databases and 22 international studies from Springer, Sage, and ScienceDirect, using a descriptive-analytical methodology.
The findings revealed significant differences in practices. Arab studies focus on the final short scale using classical methods to assess psychometric properties, often lacking detailed justifications and documentation. In contrast, non-Arab studies provide comprehensive frameworks, clear rationales for item selection and reduction, and transparency in procedures.
The study highlights the importance of clarity and methodological rigor in developing short-form scales to ensure validity and reliability. Recommendations include adopting standardized practices and providing detailed justifications for decisions to enhance the credibility of short-form scale development in future research.
