DEVELOPMENT VALIDATION OF PROPENSITY TO SEEK GENETIC COUNSELING SCALE (PSGCS)

Abstract

This study aimed to develop and validate the Propensity to Seek Genetic Counseling (PSGC) scale, a tool designed to measure the likelihood of individuals, particularly relatives of cancer patients, engaging with genetic counseling services. Existing tools have failed to account for critical psycho-clinical factors such as emotional readiness and motivational barriers. To address this, the PSGC scale was developed through a comprehensive process including literature review, expert consultations, and pilot testing among 51 relatives of cancer patients at Obafemi Awolowo University Teaching Hospital Complex. The initial 22-item scale was refined to 16 items based on item-total correlation analysis. The final scale demonstrated high internal consistency with a Cronbach's alpha of 0.92 indicating strong reliability. The PSGC scale incorporates factors such as knowledge, perceived benefits and barriers, and emotional readiness, making it a valuable tool for identifying individuals at risk of genetic conditions who may not seek counseling due to psychological or motivational challenges. This validated scale provides a reliable measure for healthcare professionals and researchers, offering potential for broader application in improving genetic counseling uptake and health outcomes.
