Background: Addiction to pornography in the virtual world can seriously affect the mental, psychological, 
social, and family health of individuals and easy access to the Internet and cyberspace has intensified 
addiction to virtual pornography. Knowledge of the status of phenomena requires an accurate and scientific 
measurement tool with appropriate validity and reliability, so this study was conducted with the aim to study 
the Youth Pornography Addiction Screening Tool (YPAST).

Methods: This study was carried out using the descriptive-exploratory method. The statistical population of 
the study included all students aged 18 to 30 years studying in the universities of Hamadan, Iran, in the 
academic year 2020-2021. Using stratified random sampling method, 480 individuals were selected from 
Bu-Ali Sina University, Islamic Azad University, and Payame Noor University of Hamadan Province. To 
collect data, the YPAST was utilized. The Cronbach's alpha coefficient, exploratory factor analysis (EFA) with 
Varimax rotation, and confirmatory factor analysis (CFA) were used to analyze the data.

Findings: The YPAST consists of the 3 components of lack of control over pornographic behavior, regret after 
pornography use, and pornography for sexual arousal. These 3 factors together explained 61.16% of the total 
variance of pornography addiction in cyberspace, with the first, second, and third factors explaining 22.98%, 
21.79%, and 16.39% of the variance, respectively. The CFA results showed that the scale items were of 
appropriate factor loads and higher than 0.40 on each factor, and the study measurement model in the first 
and second order factor analysis was of an acceptable fit. Therefore, the YPAST had an appropriate and 
acceptable structural validity among young people. The total validity coefficient of the YPAST was 0.88 and 
that of the first, second, and third factors were 0.94, 0.93 and 0.88, respectively. The YPAST has 3 factors.

Conclusion: The YPAST can be a powerful and accurate tool for measuring youth pornography addiction and it 
can be used with confidence in various situations to measure youth virtual pornography addiction. In addition, 
it seems that the scale items have a proper coherence and fluency, which, as a unified and integrated set of 
different aspects, can measure virtual pornography addiction among young people with high accuracy.
