Examining item content validity using property fitting analysis via multidimensional scaling.
Article in International journal of methods in psychiatric research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
objectivesMultiple-item measuring instruments are frequently used in a wide range of disciplines for the purpose of research in substantive areas. The quality of items in these instruments determine to a large extent whether the results are trustworthy. In this paper, we suggested to use property fitting analysis to evaluate the appropriateness of items content validity based on explicit item property criteria.
methodsUsing Center for Epidemiologic Studies Depression scale as an example, item property fitting analyses via multidimensional scaling model was used to quantitatively evaluate the properties of items based on rating data from 12 counselors.
resultsThe results of the analyses indicated that using explicit item property criteria to select items for subsequent psychometric analyses improved the item quality in terms of reliability and factor structure.
conclusionsItem property fitting analysis seemed to provide the researcher a viable quantitative method when evaluating item content validity.
