Content Validity of a Screening Instrument for Breast Cancer Early Detection Among Asian American Women: The Cultural
1Texas A&M University, Corpus Christi, Texas, USA.
Background And Purpose:
Asian American women have the lowest mammography screening rate in the United States. There is no standardized instrument available to measure their cultural beliefs regarding screening mammography. The purpose of this study is to evaluate the content validity of the Cultural Health and Screening Mammography Belief Scale (CHSMBS) developed for this population. Procedures for Instrument Development: The content validity was examined using content validity index (CVI). Both item-level (I-CVI) and scale-level CVIs (S-CVI) were evaluated.
Results:
The instrument's I-CVIs ranged from 0.75 to 1.00, and the S-CVI was 1.00, reflecting excellent inter-rater agreement.
Conclusions:
The study has established the scale's content validity to evaluate Asian American women's use of screening mammography. Further examination of the reliability and construct validity will add further support of the scale's utility in health research and practice.
