RELIABILITY AND VALIDITY OF RUSSIAN VERSION OF DS14 SCORE FOR ISCHEMIC HEART DISEASE PATIENTS

Abstract

Aim. The aim of the study is to evaluate the factorial, construct validity and reliability of the Russian version of DS14 score among ischemic heart disease patients (IHD).Material and methods. Totally, 977 IHD patients included (334 with acute coronary syndrome and 643 with stable angina), all patients fully completed the questionnaires DS14, HADS, MSPSS and STPI.Results. The prevalence of type D among IHD patients was 31,6%. Bifactorial structure of DS14 (negative affectivity, social suppression) was confirmed by exploratory and confirmatory factor analysis, and the parameters of intrinsic relative homogeneity, Tacker-Lewis index, incremental index of relation and meanquartile approximation bias for bifactorial solution were 0,90, 0,88, 0,90 and 0,069, respectively, that witnesses on the matching of theoretical bifactorial model with experiment. Intrinsic homogeneity of the Russian version of DS14 was adequate. Cronbakh alpha for negative affectivity was 0,78, for social suppression 0,74. Mean value for correlated points for negative affectivity was 0,35, for social suppression — 0,30, that confirms the adequacy of intrinsic structure of DS14. It was found, that the negative affectivity scale positively correlates with anxiety by HADS and anxiety as personal trait by STPI, and with depression by HADS and depressivity by STPI. The same, but less prominent relations were established for social inhibition. Also there was negative correlation of openness and positive correlation with aggressiveness as personal traits by STPI.Conclusion. Russian version of DS14 matches with the English version by reliability and intrinsic structure, construct validity is confirmed by the results of correlational analysis. In general, the method can be applied for personality type D assessment in IHD patients.
