Validity and Reliability of Champion’s Health Belief Model Scale to Measure Beliefs in Breast Self-Examination Practices in Vietnamese Women
Main Article Content
Abstract
Objective: The purpose of this study was to translate, adjust and evaluate the validity and reliability of the Champion's Health Belief Model scale, so as to measure the beliefs of self-examination practices of Vietnamese women.
Material and Methods: The adaptation and psychometric characteristics test of the Vietnamese HBM scale was performed, with 40 participants, from October 2021 to June 2022. Of these, 10 women were initially randomized to adjust the translation version, and 30 women were to evaluate the reliability of the scale. The content value of the scale is measured by the opinion of 5 experts. Reliability was measured by Cronbach's alpha, while An estimation of stability is commonly assessed by a test–retest reliability analysis (ICC).
Result: The Vietnamese version of the Health Belief Model scale (V-HBMS) demonstrated good content validity, with the Items content validity index (I-CVI) score for all 42 items> 0.79. Internal consistency with Cronbach's alpha ranges from .715 to .954 and the reliability of the ICC re-test ranged from .954-.000 (p-value = 0.000) determined with good results.
Conclusion: The Vietnamese version of the Health Belief Model scale can be considered a valid tool to survey the belief of Vietnamese women in the implementation of breast self-examination behavior.
