BSTRACT
Context:
Breast cancer is the leading oncological pathology among women in Kazakhstan, where secondary prevention success relies heavily on adherence to screening programmes.
Aims:
The aim of this study is to conduct linguistic adaptation and evaluate the psychometric reliability of the Champion’s Health Belief Model Scale for identifying determinants of women’s participation in breast cancer screening.
Settings and Design:
A cross-sectional pilot study was conducted at the Republican Center for Primary Health Care in Astana.
Subjects and Methods:
The sample comprised 96 women aged 40–70 years without a history of breast cancer. Cultural adaptation followed the forward-back translation protocol. Content validity was assessed by an expert panel using the Polit and Beck methodology.
Statistical Analysis Used:
Statistical processing was performed in StatTech V4.0 using contingency tables and Pearson’s Chi-squared test to analyze the relationships. Internal consistency was evaluated via Cronbach’s alpha coefficient.
Results:
The scale-level content validity index/Ave was 1.0. While awareness of screening methods was high (91.7%), actual screening participation was 56.3%. A statistically significant association was established between screening experience and trust in the healthcare system (
Conclusions:
The adapted questionnaire demonstrates high validity and reliability. Trust in healthcare professionals serves as the primary predictor of screening adherence.
