Relationship between Barriers and Performance for Delirium Care among Hospital Nurses: The Mediating Effect of Self-confidence

Objectives: This study determined the mediating effect of self-confidence in the relationship between the barriers and performance for delirium care among hospital nurses.Methods: This study used a quantitative mediation analysis design. One hundred and seventy-eight nurses were conveniently recruited from two university hospital-affiliated nursing units. Participants completed a barriers scale, a self-confidence scale, and a performance scale for delirium care. Data were analyzed with Spearman’s correlations, regression analysis, and Hayes’s Process Macro using the bootstrap method.Results: Barriers for delirium care was correlated with self-confidence (r = -0.34, <i>p</i>< 0.001) and performance (r = -0.40, <i>p</i>< 0.001). Self-confidence for delirium care was correlated with performance (r = 0.38, <i>p</i>< 0.001). Barriers for delirium care influenced self-confidence (B = -0.854, <i>p</i>< 0.001), and performance (B = -0.272, <i>p</i>< 0.001). Self-confidence mediated the relationship between barriers and performance for delirium care (B = 0.066, <i>p</i>= 0.002). Self-confidence indirectly mediated between barriers and performance for delirium care (bootLLCI = -0.127, bootULCI = -0.013).Conclusions: In-service learning strategies and developing delirium care policies are required to enhance performance by reducing barriers and boosting self-confidence for delirium care among hospital nurses.
