Development and psychometric validation of the frontline health workers' occupational risk and characteristics in emergencies index (FORCE-index) - The covid Hospital cohort study.

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
Objectives: A lack of tools for the systematic identification of frontline health workers' changing occupational risks, characteristics, and needs, poses a major barrier to supporting vital personnel to stay in practice through health emergencies and beyond. The current study reports on the development and psychometric evaluation of the Frontline health workers' Occupational Risk and Characteristics in Emergencies index (FORCE-index). Study design: The Covid hospital study is a large, multisite, four-wave, open cohort study of frontline health workers responding to the first four waves of the COVID-19 pandemic (2020-2022). Methods: 2496 frontline health workers responded to questionnaires assessing various aspects of their work environment. Using exploratory factor analysis, we estimated the latent structure of the FORCE-index at the first and second waves. This structure was evaluated using confirmatory factor analysis at the third and fourth waves. The internal consistency of the instrument's subscales (e.g., factors) was evaluated using omega reliability, Cronbach's alpha coefficient, and mean inter-item correlation. Results: A nine-factor solution provided best fit to the data. These factors mapped onto the following aspects of the work environment; competency, stress management, familiarity, workload manageability, work performance, infection safety, personal protective equipment, social safety, and social support. Internal consistency for the full FORCE-index and the nine factors was satisfactory. Conclusions: The initial psychometric validation indicates that the FORCE-index is a valid measure which can be used by health authorities, services, and institutions to adequately and systematically assess central aspects of frontline health workers' work environment that are commonly challenged in health emergencies.
