The Swedish Occupational Fatigue Inventory (SOFI) has been tested in different languages and populations; thus, there is a need for a culturally adapted Korean version. We evaluated the psychometric properties of a Korean version of the SOFI among construction workers. The SOFI was translated into Korean and reviewed through a back-translation process involving standardized scaling procedures. Its reliability and validity were evaluated with a sample of 193 construction workers using internal consistency, item–subscale correlations, test–retest reliability, and content, construct, and concurrent validity. The Cronbach’s alpha coefficients of the total scale and each subscale were satisfactory. Item–subscale correlations and test–retest reliability were both at acceptable levels. Confirmatory factor analyses revealed that the five-factor model had acceptable model fits corresponding to the structure of the original instrument. However, some modifications were made to improve in the new context from model fit (such as χ2(95) = 113.905 (p = 0.091), CFI = 0.994, and RMSEA = 0.033, as well as the lowest AIC = 383.905). Correlation analysis showed a significant relationship of SOFI with other fatigue measures in terms of total and subscale scores. Occupational fatigue is one of the important risk factors associated with workers’ health and safety at work. The new translated instrument is a reliable and valid tool for assessing fatigue among Korean construction workers. However, this instrument should be tested extensively in other working populations to devise specific interventions concerning fatigue reduction.

Purpose. To analyse the concept of patient violence towards mental health nurses. Design and Methods. A hybrid model was adopted with literature review of 103 studies and interviews with seven mental health nurses. Findings. Patient violence was defined as a violent incident committed by patients towards nurses vulnerable to physical, verbal, emotional, and sexual violence. It was a common and frequent phenomenon with multifactorial causes and is prone to be unreported. Practice Implications. Our study findings function as the conceptual framework to measure patient violence in relevant research and allow policy development to protect mental health nurses at the practice.

The aims of this systematic review were to identify the study protocol of Virtual Reality Therapy (VRT) and review the effect of VRT among patients with Post-Traumatic Stress Disorder (PTSD). Methods: This review followed the guideline of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A systematic literature search was conducted using 12 electronic databases including gray literature with no limit of publication year. Search terms included relevant terms regarding "PTSD", "trauma", and "VRT". Among 265 studies extracted through PRISMA, 20 studies were selected and evaluated for quality assessment using the Risk of Bias tool of Cochrane's collaboration. Results: The majority of the literature focused on combat veterans and war situations (95%).Usually, each session usually took 60~120 minutes of VRT in 10~20 sessions for 5~10 weeks. The VRT equipment and contents were individually designed considering patients' traumatic experiences. Most of the studies reported the positive effects associated to reduced levels of PTSD (80%) and related symptoms, such as, depression (45%) and anxiety (25%). Conclusion: Based on our findings, further studies are required to evaluate VRT in people with PTSD, after improving study design and standardizing protocols.
