PMID 34176243WHAT IT FOUND
The Persian version of the Vaginal Penetration Cognition Questionnaire reliably measures three domains of thought in Iranian women with sexual pain disorders: catastrophic/control fear, positive cognition, and self-image concerns.
It is a valid tool for assessing these cognitive factors in clinical practice.
Key findings
01The translated questionnaire retained 20 items and organized them into three subscales: catastrophic and control cognition, positive cognition, and self-image cognition.
02Internal consistency for the three subscales was acceptable, with Cronbach's alpha values ranging from 0.817 to 0.927.
03Test-retest reliability was high, with a mean Intraclass Correlation Coefficient of 0.995.

What it does not show
The study was conducted only in Tehran, so the results may not apply to other cultural or regional groups within Iran or elsewhere. The original questionnaire had 22 items and five subscales; the Persian version reduced this to 20 items and three subscales, which may limit direct comparison with international data. Discriminant validity between the three subscales was not confirmed in the first-order analysis, suggesting the subscales are highly correlated and may not measure entirely distinct constructs. Participants reported concerns about judgment due to the taboo nature of sexual topics in the local culture, which could have influenced their responses despite anonymity measures.
Declared interests
The authors declared no conflicts of interest. The study was funded by Shahid Beheshti University of Medical Sciences.
The easy way to misread this
Do not assume this tool measures five distinct cognitive domains as the original English version did. The Persian version collapses these into three correlated subscales, and the lack of discriminant validity means these subscales may overlap significantly in what they assess.
