Investigating the Psychometric Properties of the Persian Version of the Revised Illness Perception Questionnaire in a Sample of Patients With Multiple Sclerosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionIllness perception significantly influences treatment adherence and quality of life among patients with multiple sclerosis (MS). Despite the widespread use of the Revised Illness Perception Questionnaire (IPQ-R) in different languages, a validated Persian version tailored for MS patients was lacking.
methodsA cross-sectional study was conducted with 400 Persian-speaking MS patients recruited from the MS Society of Iran between December 2023 and April 2024. The IPQ-R was translated and culturally adapted through standard forward-backward translation procedures. Validity was assessed through face, content, and construct validity (using both confirmatory factor analysis [CFA] and exploratory factor analysis [EFA]). Reliability was evaluated using Cronbach's alpha and composite reliability (CR).
resultsThe Persian IPQ-R showed strong face and content validity, with all items achieving acceptable content validity ratio (CVR) and content validity index (CVI) scores. CFA supported the original seven-factor model (χ
conclusionThis study revealed that the Persian version of the IPQ-R is a reliable and valid instrument for assessing illness perceptions in Iranian MS patients. It may serve as a valuable tool in clinical and research settings to evaluate patient beliefs and guide personalized care strategies.
