Exploring the Effectiveness of an Application Intervention on Cognitive, Learning Self-Efficacy,and Clinical Reasoning of Nurses Regarding Delirium Education in the Intensive Care Unit

Delirium cognitive

adopted the "Cognitive Care for Delirium Assessment among Nursing Staff in Intensive Care Units" questionnaire by Hou et al. (2024). The original questionnaire had 15 questions. To balance statistical indicators with "content validity" in clinical practice, 6 questions were ultimately retained after screening based on difficulty and discrimination. Each question's answer was scored as correct (1 point) or incorrect (0 points), and the scores were summed to form an individual's total score, reflecting the subject's knowledge level. The maximum score was 6 points, with higher scores indicating more accurate knowledge about delirium.

Time frame: Evaluations were conducted at three time points: baseline (T0), immediately post-intervention (T1), and four weeks post-intervention (T2).

Learning self-efficacy

Using the "Delirium Care Self-Efficacy Scale" by Chang et al. (2023), scores ranged from 13 to 65. The higher the score, the higher the self-efficacy in delirium care learning.

Time frame: Evaluations were conducted at three time points: baseline (T0), immediately post-intervention (T1), and four weeks post-intervention (T2).

clinical reasoning

The Clinical Reasoning Tendency Scale for Nursing Students (Huang et al., 2018) was used. It consists of 16 items with a total score ranging from 16 to 80 points. Higher scores indicate better clinical reasoning ability among nurses.

Time frame: Evaluations were conducted at three time points: baseline (T0), immediately post-intervention (T1), and four weeks post-intervention (T2).
