Abstract:
Objective To evaluate the feasibility,reliability and validity of the symptom identification scale for kidney yang deficiency syndrome.Methods The symptom identification scale for kidney yang deficiency syndrome developed in previous research was administered to 200 vascular cognitive impairment patients from September 2020 to September 2022 to assess feasibility through recall rate,completion rate,and completion time;reliability was measured using retest reliability,split-half reliability,homogeneity reliability,and inter-rater reliability;and validity was evaluated based on discriminant and structural validity.Results A total of 200 scales were sent out,and all of them cooperated and were completed and retrieved within 20 min.The results of reliability analysis showed that the retest reliability of the scale was 0.828 for the dimension of yang deficiency and 0.718 for the dimension of kidney qi deficiency;the Spearman-Brown coefficient of split-half reliability was 0.784;the Cronbach coefficient of the dimension of yang deficiency was 0.799,and the Cronbach coefficient of the dimension of kidney qi deficiency in the homogeneity reliability was 0.670.The results of the analysis showed that the differences between the kidney yang deficiency syndrome group and the non-kidney yang deficiency syndrome group in the yang deficiency dimension,kidney qi deficiency dimension scores and total scale scores in the discriminant validity were statistically significant(P<0.001);the KMO value in the structural validity was 0.842,and a total of two factors with eigenvalues greater than 1 were extracted,with a cumulative variance contribution rate of 58.227%.Conclusion The symptom identification scale for kidney yang deficiency syndrome demonstrates adequate reliability and validity,potentially enhancing the prediction of kidney yang deficiency in vascular cognitive impairment.However,the validity of the scale is somewhat limited and requires further refinement for clinical application.
