―Raschモデルを用いた探索的検討―

抄録

The complexity of the Sense of Coherence Scale-29 (SOC-29), marked by intricate question items and choice labels, poses a challenge in accurately capturing the construct of sense of coherence. This complexity has implications for response accuracy and data interpretation. To address this issue, the study employed the Rasch measurement model to validate the SOC-29 scale, thereby initiating a re-examining of its structure and usage.

In addition to conducting fundamental analyses such as reliability assessments, further examinations involving the Rasch measurement model estimation and item difficulty-centered statistical calculations were conducted on data obtained from 1,163 participants.

The validation of the SOC-29 scale in this study suggested potential areas for improvement in the question items and in the choice labels of the scale. In the future, methodologically resolving the problems identified on the SOC-29 scale would be beneficial. Furthermore, advancing the theoretical understanding of the measurement content through methods such as incremental validity testing would be optimal.
