AB - Objectives The purpose of this study was to develop a discriminant function for the SSCQ-P short form using new data and to investigate whether the number of items could be further reduced through reliability analysis.
Methods The analysis included survey data from 282 patients who visited an outpatient clinic at a Korean medicine hospital between February 2023 and December 2024. Linear discriminant analysis was performed using all 40 items to obtain the discriminant function coefficients and calculate accuracy of the discriminant function. To verify the accuracy of SSCQ-P short form, Total 282 data sets were divided into training data and test data in a ratio of 3:1 and model evaluation was performed. To evaluate the internal consistency of the items by constitution, item analysis was conducted using Cronbach's alpha. To reduce the number of questions, a stepwise variable selection method was used.
Results The accuracy of the discriminant function for all participants was 84.4%. The accuracy of the discriminant function for training was 86.9% and the accuracy of the discriminant function for test was 78.6%. Fifteen items were selected using the stepwise variable selection method, and the accuracy was 79.4%.
Conclusion As a result of item analysis using cronbach's alpha, the number of items related to the Taeyangin was reduced from 10 to 6, and the number of items related to the Soyangin was reduced from 10 to 9.
