Reliability and Validity of the Fatigue Severity Scale among University Student in South Korea

OBJECTIVES: There are only a limited number of studies on instruments assessing fatigue in university students, although fatigue exerts negative influences on their health and academic performances and fatigue-related complaints are more frequently reported in young adults than middle-aged adults. The aim of this study was to validate the 9-item Fatigue Severity Scale (FSS) among university students including both undergraduate and graduate students in South Korea. METHODS: A total of 176 university students completed a battery of self-report questionnaires, including the FSS, the Brief Fatigue Inventory (BFI), the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), the Medical Outcomes Study Short Form 36 version 2 (MOS-SF36v2), and the Inclusion of Community in the Self Scale (ICS). The data were collected from February of 2012 to June of 2012. The reliability, convergent validity, divergent validity, and exploratory factor analyses were conducted to assess psychometric properties of the FSS. RESULTS: The mean FSS score was 3.20 (standard deviation = 1.43). The FSS demonstrated an excellent internal consistency (Cronbach's alpha = 0.93) and item-total correlations ranged from 0.56 to 0.90. Correlations of the FSS with the BFI (r = 0.71, p < 0.01), BDI-II (r = 0.54, p < 0.01), BAI (r = 0.46, p < 0.01), MOS-SF36v2 physical component summary (r = -0.28, p < 0.01), MOS-SF36v2 mental component summary (r = -0.55, p < 0.01), and ICS (Spearman's rho = -0.07, p = 0.33) showed acceptable convergent and divergent validity. Exploratory factor analysis defined one underlying factor (eigenvalue = 5.67) that explained 93.50% of the total variance. CONCLUSIONS: To the best of our knowledge, this is the first study to investigate reliability and validity of the FSS in university students. The FSS exhibits good psychometric properties for evaluation of fatigue among university students in South Korea. Since the FSS is easy to administer, score, and interpret, it could be a useful tool in research and practice for assessing fatigue among university students.

Prevalence and Associated Risk Factors of Psychological Distress in Patients with Gastric Cancer / 정신신체의학

OBJECTIVES: Though gastric cancer is one of the most common cancer in Korea, there have been few studies to explore psychological distress in gastric cancer. The purpose of this study was to investigate the prevalence and associated risk factors of psychological distress among patients with gastric cancer. METHODS: With consecutive sampling, a total of 274 patients with gastric cancer who admitted to a cancer center in a general hospital were recruited and assessed on psychological distress using the Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer-related clinical variables were also evaluated. RESULTS: One hundred fifty-three(55.8%) patients with gastric cancer showed psychological distress. Logistic regression models revealed that having alcohol drinking experience[odds ratio(OR)=2.10, p=0,034] and low performance status(OR=2.40 p=0.002) were significantly associated with psychological distress in patients with gastric cancer. CONCLUSIONS: These findings indicate that approximately half of patients with gastric cancer suffered from psychological distress and having alcohol drinking experience and low performance status would be associated risk factors, suggesting the need for distress screening and psychosocial supportive care in patients with gastric cancer.
