Lung Cancer Screening Health Belief Model: Psychometric Properties of the Arabic Version and Factors Influencing...

Several screening models have recently been applied to study awareness and help people make informed decisions regarding cancer screening.

This study aimed to explore the knowledge, attitudes, and lung cancer screening health beliefs (LCSHBs) among Jordanians. Moreover, we intended to translate the LCSHBs scale into the Arabic language and test its validity and reliability.

An online survey (Google Forms) was completed by 916 participants in Jordan via snowball sampling technique from February 10, 2024, to March 2, 2024, assessing lung cancer screening knowledge, lung cancer preventive attitudes, screening-related health beliefs, and stages of screening adoption. Linear regression analysis, correlations, and non-parametric statistics were utilized for statistical inference.

Participants had high mean percentage scores of 86.56% and 85.75% for knowledge and preventive attitudes towards lung cancer screening, respectively. The Arabic version of the LCSHBs model was found to be a valid and reliable tool, as indicated by principal component analysis extraction and Cronbach's alpha values. Lung cancer screening knowledge was positively associated with perceived benefits and negatively associated with perceived barriers to screening. Knowledge, perceived barriers, perceived risk of lung cancer, self-efficacy (SE) to screen, and lung cancer preventive attitudes were significantly associated with the perceived benefits of lung cancer screening (p < 0.05). We also found that the higher the SE, the higher the physical activity and the lower the perceived barriers.

The Arabic version of the LCSHBs model is valid and reliable for assessing health beliefs toward lung cancer screening. We recommend enhancing targeted interventions, educational outreach, and improving health insurance access to reduce lung cancer incidence in Jordan and promote screening behaviors.
