Development and Validation of the EBP-Affinity Questionnaire: A Mixed-Method Study.
Article in Nursing open, 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
backgroundImplementation of evidence-based practice (EBP) in nursing homes is important to improve quality of care and reduce costs. These facilities primarily employ certified nurse assistants (CNAs) and vocationally-trained registered nurses (VTRNs). Although EBP is scarcely addressed in their education, these caregivers have an important role in EBP. Insight into their affinity with EBP could provide a good starting point for working according to EBP.
aimsTo develop a questionnaire that measures affinity with EBP amongst CNAs and VTRNs in nursing homes. To assess the reliability and validity of the questionnaire.
designMixed-method design according to the COSMIN-checklist.
methodsPhase 1: the questionnaire was developed in three steps: (1) gathering items from existing questionnaires, occupational profiles and interviews; (2) compression through consensus rounds and (3) a pilot study. Phase 2: psychometric properties were assessed amongst CNAs and VTRNs in nine nursing homes. The factors extracted through principal component analysis were tested for measurement invariance using the one-parameter Rasch model.
resultsPhase 1: all experts interviewed (N = 5) indicated CNAs and VTRNs can play specific and significant roles in EBP. A 26-item questionnaire was created through two consensus rounds with experts (N = 7) and a pilot study (N = 7). Phase 2: Principal component analysis revealed a two-factor structure with good internal reliability (N = 428 questionnaires). All items exhibited good fit with the Rasch model and measurement invariance for CNAs and VTRNs.
conclusionCNAs and VTRNs can fulfil important roles in EBP in nursing homes. The 'Evidence-Based Practice-Affinity Questionnaire' is reliable and valid for assessing affinity with EBP amongst CNAs and VTRNs to improve practice and research, and can guide tailored training programs for CNAs and VTRNs, enhancing evidence-based practices in nursing homes. IMPACT: The research provides insight into the roles CNAs and VTRNs can play in EBP and how to measure their affinity with EBP, which contributes to implementation of EBP in nursing homes. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution in the study.
