[Development of the CT Scan Attitude Scale and Evaluation of Its Reliability and Validity]

Ensuring that patients undergo examinations with confidence and ease is crucial. This study aims to develop a reliable and valid CT Scan Attitude Scale (CT-SAS) to measure attitudes toward CT scans objectively.

In Study 1, question items were developed based on preliminary surveys and prior research. A survey involving 497 screening participants was conducted to refine the scale. Factor analysis was employed to select appropriate items, estimate a factor model, and assess the reliability of the scale. In Study 2, the CT-SAS was administered to 496 university students, and its validity was evaluated by comparing their responses with those of screening participants.

Study 1 resulted in the development of a 10-item, 3-factor scale, with all model fit indices meeting established criteria. Reliability coefficients (Cronbach's α) for each factor ranged from 0.850 to 0.751, indicating high internal consistency. In Study 2, university students demonstrated significantly higher scores on each factor, supporting the scale's validity.

This study successfully developed and validated the CT Scan Attitude Scale, a tool for assessing attitudes toward CT scans. Future research should explore how interventions targeting examination attitudes can influence outcomes using this scale.
