Improving mental healthcare using mobile apps might be an effective way to increase interest in mental health and respond to the demand for better psychological health. However, few studies have investigated the effectiveness of app-based stress-management programs. This study aimed to assess the efficacy of an app-based stress-management program. A non-equivalent comparison group pretest-posttest design was used. Participants were randomized into the experimental (n = 26) and control (n = 30) groups. The experimental group used an application developed for workers for four weeks. The results indicated that stress, emotional labor, self-efficacy, and well-being were significantly different in the experimental group, but the control group’s average scores did not change significantly. On average, the Perceived Stress Scale scores decreased by 1.5 points (p = 0.035) and the Korean Occupational Stress Scale scores decreased by 0.87 points (p = 0.4). However, depression and anxiety were not significantly different. Emotional labor decreased by 0.16 points (p = 0.027), and well-being and self-efficacy mean scores increased by 0.492 (p = 0.005) and 0.162 (p = 0.025), respectively. These findings support the developed application’s value for promoting mental health and healthy lifestyles. Further research and supplementation are needed for the application’s sustainability.

Purpose: With globalization, the importance of global health is being stressed. Although nurses are indispensable healthcare professionals, programs to develop nurses with global health competencies and relevant studies are rare. Accordingly, this study was designed to develop a program to increase global health competencies and global leadership in nursing students and test its effect. Methods: A single group pre- and post-test study design was used. A 13-weeks program was developed and implemented with 204 students. Data were analyzed using paired t-test. The program to promote global health competencies was designed to improve nursing students' knowledge of global health, global leadership, global health competencies, critical thinking ability, and student-student partnership. Results: Global health competencies (t = −19.96, p < 0.001), self-assessed global leadership (t = −7.67, p < 0.001), and critical thinking ability (t = −7.67, p < 0.001) all significantly increased. Discussion: The study findings of increased global health competencies and global leadership in nursing students after participation in the program indicated ways in which global health competencies of nurses need to be developed. Therefore, the following aspects should be considered. First, nursing educators should understand the need and importance of global health education and accordingly, current nursing curriculums should be revised to include courses about global health. A systematic course of studies about global health should be developed and implemented based on discussions among experts and researchers. Second, as future health care professionals, nursing students should take an interest in global health problems and recognize various issues that need to be solved beyond borders between countries. To develop global health competencies, various efforts and systematic curriculum revisions are necessary.

It has become important for nurses to implement self-leadership and exercise critical thinking in problem-solving to address the health issues of patients. This has led to a need for nursing education programs in which nursing students learn to embrace self-leadership and self-evaluation approaches to develop their skills. Within 260 nursing undergraduates with experience in simulation practice as study subjects, a self-reporting survey was conducted on self-leadership, goal commitment, critical thinking, and problem-solving skills. An analysis was conducted using the SPSS/WIN 21.0 program. t-test and ANOVA were conducted to validate the difference between problem-solving abilities. Multiple regression was conducted to examine the impact of these variables on problem-solving skills. The variables of religion, satisfaction with major, goal commitment, and critical thinking were found to have a significant impact on problem-solving abilities. The results were as follows: critical thinking (β = 0.36, p < 0.05), goal commitment (β = 0.28, p < 0.05), and explanatory power of 41%. To improve the nursing undergraduates’ problem-solving abilities through simulation practice, there needs to be a method that supports them in setting goals with self-leadership and enhance goal commitment. The method also needs to support the development of their critical thinking and curiosity for questions deriving from experiencing diverse programs in order to deliver effective outcomes.

Purpose: There has been a recent surge in interest in mental health and how to improve individuals’ health-related quality of life. Mental health management using mobile apps can be a useful intervention method. The development and application of verified and highly efficient apps for mental health and stress management are needed. We developed healing programs and verified their effectiveness based on apps designed to promote adult mental health. Methods: We conducted a one-group pretest-posttest study in which 85 participants used the app for 12 weeks. We assessed its effects on participants’ stress (perceived stress scale, effort–reward imbalance, and photoplethysmogram (PPG)), anxiety, depression, emotional labor, and well-being. Results: The stress survey results post-intervention increased or stayed the same; however, the PPG results decreased (p = 0.002) after using the app. Depression (p = 0.043) and anxiety (p = 0.003) also decreased; however, emotional labor and well-being remained unchanged. The awareness of, knowledge of, and attitude toward mental health management all increased post-intervention. Discussion: The developed mobile app was an efficient and highly accessible way to promote mental health. However, the app requires modification and supplementation for continual use. Additionally, ongoing research concerning the study, evaluation, and integration of mobile apps is required.

Wellness in adult workers is intimately associated with better quality of life in individuals, as well as in the family, community, workplace, and country. This study aimed to examine the status of wellness in adult workers and to identify the factors that influence wellness. A descriptive survey was conducted with 260 adult workers. T- test and one-way ANOVA with post-hoc Scheffe test were used to analyze the data. Multiple regression analysis was performed on stress, depression, anxiety, well-being, self-efficacy, and perceived health status. The regression model for wellness in adult workers was significant (F = 42.21, p < 0.001), with an explanatory power of 0.558. Depression (β = −0.306) was identified as the most influential factor for wellness in adult workers, followed by self-efficacy (β = 0.280) and well-being (β = 0.264). Depression, stress, and anxiety negatively influenced wellness, whereas self-efficacy, well-being, and perceived health status positively influenced wellness. Study findings suggest the need to develop intervention programs for workers that decrease stress, depression, and anxiety, and incorporate self-efficacy strategies.
