Purpose
This study aimed to conduct a systematic review to explore leadership-related variables among nurses in the novice and advanced beginner stages, identify research trends, and analyze effect sizes to provide evidence for developing a nursing leadership program. Methods: A systematic review and meta-analysis were conducted according to PRISMA(Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and NECA (National Evidence based Healthcare Collaborating Agency) guidelines. Literature was searched from February 26 to April 26, 2024 using databases including KISS, KMbase, RISS, KoreaMed, Science ON, CINAHL, CENTRAL, Embase, PubMed, Web of Science, and Korean nursing journals. Meta-analysis was performed using R version 3.6.2. Results: From 589 articles, five studies were selected. Self-leadership was most frequently studied topic (80.0%). Leadership antecedents with k≥2 included preceptor’s clinical teaching behavior (correlation effect size [ESr], 0.34). For leadership outcomes, effect size analyses for cases with k≥2 indicated resilience (ESr, 0.72), nursing performance (ESr, 0.69), and organizational socialization (ESr, 0.31), with resilience demonstrating the largest effect. Conclusion: Preceptor’s clinical teaching behavior, resilience, nursing performance, and organizational socialization were identified as critical factors in leadership of the nurses at novice and advanced beginner stage. Enhancing leadership requires preceptor support, which can improve resilience and help early-career nurses overcome challenges. Therefore, strategies for leadership development must include specific measures to ensure preceptor support.

Purpose
The purpose of this study is to provide academic basic data by quantitatively integrating variables related to information literacy competence of Korean nursing students. Methods: This study is a meta-analysis study to systematically review the research on information literacy competence of Korean nursing students and related variables to identify the effectiveness of each variable group. The selection criteria for the analysis subjects were determined using the PICOS framework in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) systematic review reporting guidelines. Theses and journal articles published from September 1, 2024, to September 30, 2024, were searched. Results: The effect sizes of the sub-variables of each variable group showed that the personal thinking competence group showed the largest effect size in the order of problem-solving ability (Fisher’s Z=.90) and critical thinking ability (Fisher’s Z=.57); the professional competence group showed evidence-based practice (Fisher’s Z=.84), clinical performance (Fisher’s Z=.65), learning engagement (Fisher’s Z=.51), communication ability (Fisher’s Z=.49), and academic achievement (Fisher’s Z=.45); and the professional competence group showed privacy awareness (Fisher’s Z=.51), professionalism (Fisher’s Z=.42), and ethical awareness (Fisher’s Z=.41). Conclusion: Based on the results of this study, it is necessary to develop a program to strengthen the information literacy competence of nursing students. Furthermore, there is a need to develop curricula and teaching-learning strategies to enhance information utilization capabilities, along with sustained attention to practice-based educational models tailored to AI and digital environments.
