Psychometric parameters of the Spanish version of the Kuwait University Anxiety Scale (S-KUAS)

To construct a Spanish version of the Kuwait University Anxiety Scale (S-KUAS), the Arabic and English versions of the KUAS have been separately translated into Spanish. To check the comparability in terms of meaning, the two Spanish preliminary translations were thoroughly scrutinized vis-a-vis both the Arabic and English forms by several experts. Bilingual subjects served to explore the cross-language equivalence of the English and Spanish versions of the KUAS. The correlation between the total scores on both versions was 93, and the t value was .30 (n.s.), denoting good similarity. The alphas and 4-week test-retest reliabilities were greater than .84, while the criterion-related validity was .70 against scores on the trait subscale of the STAI. These findings denote good reliability and validity of the S-KUAS. Factor analysis yielded three high-loaded factors of Behavioral/Subjective, Cognitive/Affective, and Somatic Anxiety, equivalent to the original Arabic version. Female (n = 210) undergraduates attained significantly higher mean scores than their male (n = 102) counterparts. For the combined group of males and females, the correlation between the total score on the S-KUAS and age was -.17 (p < 0.01). By and large, the findings of the present study provide evidence of the utility of the S-KUAS in assessing trait anxiety levels in the Spanish undergraduate context.
