The table indicates item statistics, factor loadings, corrected item-total correlations (CI-TC) and Cronbachs alpha correlation coefficients estimated in n = 194. Values of factor loadings are results of the pattern matrix. Bold face indicates loadings with absolute values of 0.6 or more. Loadings < 0.4 are not reported with exception of the values of F7, which has only low loadings. The 3-factor solution explained 49.2% of the variance. Abbreviations: E indicates emotional subscale; F, functional subscale; P, physical subscale of the Dizziness Handicap Inventory - German version; load indicates factor loading. |
