| Summary: | Abstract Background Health behavior plays a major role in the development, progression, and prognosis of cancer. The Health Behavior Scale for Cancer Patients (HBSCP) can be used to assess the level of health behavior in cancer patients. This study aimed to explore its psychometric properties and Measurement Invariance (MI) in the Chinese cancer population. Methods A longitudinal study was conducted with 567 cancer patients across two hospitals, and 428 participants underwent a second assessment three months later. Analyses were performed to evaluate reliability (internal consistency), validity (structural validity, convergent validity, and criterion-related validity), and MI of the Chinese version of the HBSCP. Results The two-factor structural model of the 9-item scale demonstrated an excellent fit in Confirmatory Factor Analysis (CFA). Psychometric analyses indicated strong internal consistency, with Cronbach’s alpha coefficients ranging from 0.846 to 0.899 and McDonald’s Omega values between 0.847 and 0.897. Convergent validity was supported by Composite Reliability (CR > 0.70) and Average Variance Extracted (AVE > 0.50). Criterion-related validity was established via significant correlations with the Health-Promoting Lifestyle Profile II (HPLP-II; r = 0.653 ~ 0.760). Multi-group CFA further confirmed MI across cancer types (ΔCFI&TLI < 0.01; ΔRMSEA < 0.015) and time groups (3-month interval). Conclusions This study provides longitudinal evidence supporting the adequate psychometric properties and temporal stability of the Chinese version of the HBSCP, thus validating its utility for measuring health behavior in Chinese cancer populations. The Chinese HBSCP can serve as a tool for healthcare providers to assess the current status and changes in health behavior among cancer patients. |
