Psychometric Properties of a Pictorial Scale Measuring Correct Condom Use

This study was designed to assess the psychometric properties of a pictorial scale of correct condom use (PSCCU) using data from female sex workers (FSWs) in China. The psychometric properties assessed in this study include construct validity by correlations and known-group validation. The study sample included 396 FSWs in Guangxi, China. The results demonstrate adequate validity of the PSCCU among the study population. FSWs with a higher level of education scored significantly higher on the PSCCU than those with a lower level of education. FSWs who self-reported appropriate condom use with stable partners scored significantly higher on PSCCU than their counterparts. The PSCCU should provide HIV/STI prevention researchers and practitioners with a valid alternative assessment tool among high-risk populations, especially in resource-limited settings.
