Evaluation of reliability and validity of the Chinese version of Acceptance Illness Scale

Objective To evaluate the reliability and validity of the Chinese version Acceptance of Illness Scale (AIS-CHI) . Methods By translation, back-translation, culture debugging of the original version of AIS, the AIS-CHI was acquired. From October 2016 to March 2017, we conducted questionnaire survey on 89 patients with initial stroke in the neurological department of the Second Affiliated Hospital of Harbin Medical University selected by convenience sampling method to evaluate the reliability and validity. Results The scale-level content validity index (S-CVI) of the AIS-CHI was 0.925. Item-to-total correlation analysis shows that each item scores was positively correlated with total score (P<0.05) . The KMO value was 0.611, while the spherical test value of Bartlett was 167.992 (P<0.001) . 3 common factors from exploratory factor analysis explained cumulatively 64.36% of variance. The internal consistency Cronbach's α of AIS-CHI was 0.754. Conclusions AIS-CHI has good reliability and validity, and it can be used to assess the patient's acceptance of disease.
