Background: The Short Health Anxiety Inventory (SHAI) is widely used in
English-speaking populations, with good reliability and validity. For further
research needs in the Chinese population, it was translated into a Chinese
version (CSHAI). Furthermore, the reliability, validity, and cutoff score were
examined in a nonclinical population in the People’s Republic of China.
Methods: Three hundred and sixteen undergraduates were evaluated by a set of questionnaires including CSHAI, Zung Self-Rating Anxiety Scale (SAS), Zung Self-Rating Depression Scale (SDS), and the State-Trait Anxiety Inventory (STAI). Fifty-eight students completed CSHAI again after 30 days.
Results: The two-factor model had satisfactory fit indices. The correlation coefficients between each item with the CSHAI total and each subscale were between 0.386 and 0.779. The Cronbach’s alpha coefficients of CSHAI total and its subscales were 0.742, 0.743, and 0.788, respectively, and the split-half coefficients were 0.757, 0.788, and 0.912. The test–retest correlation coefficients were, respectively, 0.598 (P <0.001), 0.539 (P <0.001), and 0.691 (P <0.001). Convergent validities were respectively 0.389–0.453, 0.389–0.410, and 0.250–0.401, and discriminant validities were -5.689 (P <0.001), -5.614 (P <0.001), and -3.709 (P <0.001). The cutoff score was 15.
Conclusion: CSHAI showed good factor structure, reliability, convergent validity, and discriminant validity, and 15 was determined to be the appropriate cutoff score for screening health anxiety.
Keywords: health anxiety, confirmatory factor analysis, cutoff score
