Development and psychometric testing of the Competence in Work Ability Risk Management and Analysis (Comp-WARMaA) instrument: a methodological study.
Article in BMC nursing, 2026. 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
backgroundWork ability risk management and analysis (WARMA) requires professional competence to ensure effective, consistent, and high-quality occupational health nursing. Occupational health nurses (OHNs) play a central role in identifying and addressing work ability risks; however, no comprehensive instrument currently exists to assess their competence. This study aimed to develop and psychometrically evaluate such an instrument.
methodsA descriptive, exploratory, and methodological design was applied. Instrument development followed a three-phase process comprising theory-based item generation, expert panel evaluations with consensus meetings, and empirical testing. Data were collected using two online surveys including the newly developed Competence in Work Ability Risk Management and Analysis (Comp-WARMaA) instrument. Psychometric properties were examined using classical and modern test theory methods, focusing on content validity, internal consistency, and structural validity.
resultsThe final Comp-WARMaA instrument comprised 40 items covering four competence domains: objective knowledge, perceived knowledge, attitudes and values, and case-based performance. Content validity was confirmed by experts. Internal consistency was acceptable across subscales. Principal component analysis supported the multidimensional structure, whereas confirmatory factor analyses (CFA) and Rasch analyses yielded mixed findings, indicating the need for further refinement and psychometric testing in independent samples.
conclusionsThe Comp-WARMaA instrument demonstrated strong content validity and acceptable internal consistency. Structural analyses yielded mixed findings, indicating the need for further refinement and psychometric testing in independent samples. The instrument provides a structured framework for assessing OHNs’ competence in WARMA and may inform systematic competence evaluation and professional development in occupational health nursing. CLINICAL TRIAL NUMBER: Not applicable.
