When better is the enemy of good: two cautionary tales of conceptual validity versus parsimony in clinical psychometric research.

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
This paper presents an empirical challenge to the assumption that an item-response theory analysis always yields a better measure of a clinical construct. We summarize results from two measurement development studies that showed that such an analysis lost important content reflecting the conceptual model ("conceptual validity"). The cost of parsimony may thus be too high. Conceptual models that form the foundation of QOL measurement reflect the patient's experience. This experience may include concepts and items that are psychometrically "redundant" but capture distinct features of the concept. Good measurement is likely a balance between relying on IRT's quantitative metrics and recognizing the importance of conceptual validity and clinical utility.
