Translation and measurement properties of Persian version of Child-to-Parent Violence Questionnaire.

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
objectiveChild-to-parent violence (CPV) has received limited attention in scientific literature, but due to a recent increase in reported cases, it has become a subject of investigation. The reliability and validity of the Child-to-Parent Violence Questionnaire (CPV-Q), in separate mother and father versions, have not yet been studied in Iran. This study aimed to assess the psychometric properties of the Persian CPV-Q.
designThis research employed a cross-sectional design to evaluate the Persian CPV-Q's psychometric properties. The process included translation (using backward-forward method), face validity (via impact score calculation), content validity (using content validity ratio (CVR) and content validity index (CVI)), construct validity (through exploratory and confirmatory factor analyses (CFA)) and reliability assessment (via test-retest, coefficient α, coefficient ω and intraclass correlation coefficient (ICC)).
settingThe study was conducted at the Faculties of Tabriz University of Medical Sciences.
participantsA total of 500 qualified students from Tabriz University of Medical Sciences were recruited using cluster random sampling. These participants completed the Persian CPV-Q.
resultsFace validity was confirmed, with impact scores exceeding 1.5 for all items. Content validity was strong, with CVR=0.92 and CVI=0.89. Exploratory factor analysis revealed four factors related to violence frequency and two factors regarding reasons for violence, consistent with the original questionnaire, covering 19 and 8 items, respectively. Total variance explained was 0.30 and 0.39 for the mother's version and 0.33 and 0.43 for the father's version in frequency and reason sections. The Kaiser-Meyer-Olkin test confirmed sample adequacy (<0.001). Items were removed from both versions due to statistical insignificance, zero variance or collinearity. CFA supported the model fit. Reliability metrics showed coefficient α of 0.81 (mother) and 0.80 (father), coefficient ω of 0.77 (mother) and 0.74 (father), and ICC (95% CI) values of 0.72 (0.42 to 0.87) (mother) and 0.79 (0.56 to 0.90) (father), indicating good reliability.
conclusionsThe Persian CPV-Q demonstrates adequate validity and reliability for assessing the prevalence and causes of CPV in Iranian society.
