Efficacy and safety of digital therapeutic application of Sleep Index-Based Treatment for Insomnia (dSIBT-I): a pilot study.

The aim of this study was to evaluate the safety and efficacy of digital therapeutic application of Sleep Index-Based Treatment for Insomnia (dSIBT-I) and compare them with those of digital application of Cognitive Behavioural Therapy for Insomnia (dCBT-I). This randomised prospective pilot study was conducted at the Asan Medical Center. A total of 50 patients with insomnia were recruited between December 2022 and January 2023 and randomly allocated to the dSIBT-I or dCBT-I group. The study was carried out for one month. The primary outcome was the significant reduction in Insomnia Severity Index score at Week 4 compared to baseline, while the secondary outcome was proportion of participants whose Insomnia Severity Index scores were reduced to <15 at Week 4. We performed linear mixed model and generalised estimating equation analyses. Both dSIBT-I and dCBT-I groups showed significant improvements in Insomnia Severity Index scores at Week 4. There was no significant difference between two groups in terms of Insomnia Severity Index scores at Week 4 (group × time effect, F = 1.07, p = 0.382) and proportion of participants whose Insomnia Severity Index scores were reduced to <15 at Week 4 (group × time effects, F = 1.80, p = 0.615). However, at Week 2, the dSIBT-I group showed better results than the dCBT-I group in terms of both Insomnia Severity Index scores (p = 0.044) and proportion of participants whose Insomnia Severity Index scores were reduced to <15 (82.6% vs. 48.0%, p = 0.017). No treatment-emergent adverse events were reported in either group. The dSIBT-I is a safe and effective therapy for insomnia, with rapid treatment effects.

Mediating Effect of Public Service Motivation and Resilience on the Association Between Work-Related Stress and Work Engagement of Public Workers in the COVID-19 Pandemic.

OBJECTIVE: We aimed to explore the influence of public workers' distress or viral anxiety on their level of depression and work engagement during the coronavirus disease (COVID-19) pandemic. Additionally, we ascertain the mediation effect of resilience and public service motivation on this association. METHODS: A total of 300 public workers participated in this online survey. Their demographic characteristics and responses to survey items were collected using the Stress and Anxiety to Viral Epidemics-6 items Scale, the Patient Health Questionnaire-9 items Scale, the Public Service Motivation (PSM) Scale, the Nine-item Utrecht Work Engagement Scale, the Korean Occupational Stress Scale-Short Form, and the Brief Resilience Scale. RESULTS: Work engagement of public workers was expected by PSM (ß=0.28, p<0.001), resilience (ß=0.30, p<0.001), and work-related stress (ß=-0.40, p<0.001) (F=57.4, p<0.001). Depression was expected by fewer years of employment (ß=-0.12, p=0.02), viral anxiety (ß= 0.21, p<0.001), and low resilience (ß=-0.42, p<0.001) (F=22.1, p<0.001). Resilience and PSM partially mediated the effects of work-related stress on work engagement. Depression was influenced by COVID-19-induced viral anxiety, and their resilience-but not PSM-mediated the association. CONCLUSION: Public workers' resilience and PSM partially mediated the effects of work-related stress on work engagement. The influence of viral anxiety on public workers' depression was mediated by their resilience but not PSM.

Healthcare Workers' Resilience Mediates the Influence of Organizational Commitment and Anxiety Response to Viral Epidemic on Their Quality of Life in the COVID-19 Pandemic.

Objective: In the COVID-19 pandemic era, healthcare workers suffer from psychological problems such as anxiety in response to the viral epidemic and it may decrease their quality of life (QoL). The aim of this study was to explore the influence of healthcare workers' stress and anxiety response to the viral epidemic and their organizational commitment on their QoL. We also explored the mediating effect of resilience on any association. Methods: From January 28, 2021, to January 29, 2021, 389 workers responded to an online survey that included the rating scales Stress and Anxiety to Viral Epidemics-9 items (SAVE-9), Perceived Stress Scale (PSS), Brief Resilience Scale (BRS), Organizational Commitment Questionnaire (OCQ), and the WHO-5 well-being index. Results: A better QoL (WHO well-being index top 25%) of healthcare workers during the COVID-19 pandemic era was predicted by low stress and anxiety in response to the viral epidemic [SAVE-9, adjusted odds ratio (aOR) = 0.92, 95% confidence interval (CI) 0.87-0.97], a high level of resilience (BRS, aOR = 1.26, 95%CI 1.15-1.37), and high organizational commitment (OCQ, aOR = 1.04, 95%CI 1.02-1.07). Mediation analysis showed that resilience partially mediated the effects of stress/anxiety in response to the viral epidemic and the organizational commitment on the quality of life. Conclusion: We observed that the stress and anxiety of healthcare workers in response to the viral epidemic and organizational commitment influenced their QOL. Their resilience mediated the relationship between their psychological problems and QOL.
