Abstract

Purpose: This paper critically examines the extent to which simulation exposure produces measurable, transferable clinical competence rather than perceptual learning gains. It interrogates the causal, psychometric, and curricular assumptions underpinning simulation adoption and evaluates whether statistically significant outcomes reflect authentic professional capability.

Design/Methodology: A quantitative, explanatory research design is adopted. Drawing on a simulated multi-institutional dataset grounded in effect sizes reported in prior meta-analyses, the study models the relationship between simulation intensity, fidelity level, and competency outcomes using multiple regression, structural equation modelling, and independent sample tests. Competency is operationalised through objective structured clinical performance scores rather than self-reported confidence.

Findings: Preliminary modelling indicates that simulation exposure significantly predicts competency outcomes; however, the magnitude of effect varies by fidelity, debriefing quality, and curricular integration. High-frequency simulation without theoretically aligned facilitation demonstrates diminishing returns. Confidence-based outcome measures inflate perceived effectiveness and weaken predictive validity for clinical performance. Competency gains are strongest when simulation replaces—rather than supplements—poorly structured clinical hours.

Originality/Value: This study moves beyond descriptive advocacy by statistically disentangling the pedagogical, psychological, and structural variables that mediate simulation effectiveness. It challenges the assumption that technological sophistication equates to competency development and provides a mathematically grounded framework for curriculum reform, resource allocation, and evidence-based simulation policy in nursing education.
