Development and psychometric evaluation of the child marriage cognitive determinants questionnaire (CMCDQ): a mixed-methods study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Child marriage (CM) is prevalent in Iran. Family members are most commonly the final decision-makers to accept a marriage proposal, often without girls' involvement. Valid and reliable instruments are needed to assess the contributing factors of CM. This study aimed to develop and evaluate the Child Marriage Cognitive Determinants Questionnaire (CMCDQ). An exploratory sequential mixed methods research design was conducted from 2021 to 2022 in Sanandaj, Iran. The CMCDQ was developed through a qualitative survey of 41 parents, men and women with a history of CM, and experts and a literature review. Then, its primary face, content, construct validity, and reliability were assessed. Construct validity was evaluated by exploratory and confirmatory factor analyses on the data obtained from 500 parents. The primary CMCDQ had 83 items. In face and content validity assessments, 31 items were deleted because their item impact scores were less than 1.5 (n = 3), content validity ratios were less than 0.59 (n = 23), and content validity indices were less than 0.79 (n = 5). Seven items were revised because their content validity indices were 0.7-0.79. In exploratory factor analysis, six items were deleted because their factor loading values were less than 0.3 and the remaining 46 items were loaded on eight factors, namely cultural perception, parenting skills, attitude, situational influences, subjective norms, factual beliefs, neutralization, and personal normative beliefs. These factors explained 56.55% of the total variance. Confirmatory factor analysis confirmed the good fitting of the eight-factor model (CMIN/DF = 1.039, PCFI = 0.938, PNFI = 0.964, NFI = 0.945, IFI = 0.963, CFI = 0.995, RFI = 0.949, GFI = 0.961, AGFI = 0.952 and RMSEA = 0.013). The Cronbach's alpha values and the intraclass correlation coefficients of CMCDQ subscales were 0.7-0.8 and 0.8-0.9, respectively. CMCDQ is a valid and reliable instrument and can be used to assess the parental cognitive determinants of CM and develop effective strategies to minimize CM.
