Psychometric properties and cross-cultural adaptation of the HPV testing knowledge scale: a cross-sectional methodological study among Turkish women

Abstract: This study aimed to investigate the psychometric properties of the Human Papillomavirus Testing Knowledge Scale (HPV-TKS) among Turkish women.

Design

A cross-sectional methodological study.

Setting

Data were collected through an online survey conducted in Türkiye between September 2023 and February 2024, using non-probability convenience and snowball sampling.

Participants

A total of 234 women were initially recruited, of whom 205 met the inclusion criteria and were included in the final analysis. Eligible participants were women aged 30–65 years who were able to read and understand Turkish and provided informed consent. Women with a history of total hysterectomy or cervical cancer were excluded. Primary and secondary outcome measures: The primary outcomes were the validity and reliability of the HPV-TKS. Content validity was assessed using the Content Validity Index (CVI), and structural validity was evaluated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Convergent validity was assessed using average variance extracted, known-groups and discriminant validity were assessed using independent-samples t-tests and criterion validity was assessed using logistic regression. Reliability was examined using Cronbach’s alpha, McDonald’s omega and item-total correlations, along with floor/ceiling effects.
