A Study on Reliability and Validity of the Nurses' Global Assessment of Suicide Risk (NGASR) for Psychiatric Inpatients / 정신간호학회지

PURPOSE: Assessment of suicide risk is a critical task for nurses, especially for nurses working with psychiatric inpatients. The purpose of this study was to verify the reliability and validity of the Nurses' Global Assessment of Suicide Risk (NGASR) for psychiatric inpatients. METHODS: This study was methodological study. A scale composed of 15 items was used with 106 psychiatric inpatients in open and closed psychiatric units of a tertiary hospital. Cohen's kappa coefficient, Intraclass correlation, factor analysis and Jonckheere-Terpstra Test for Ordered Alternatives were used for statistic analysis. RESULTS: Main results were as follows; Reliability of the scale was supported with a total intraclass correlation coefficient of .890 (range from .722 to 1.000). In investigating construct validity, 15 items loaded on six factors which explained 63.4% of total variance. Also the Jonckheere-Terpstra test revealed a significant trend in the order of median scores of NGASR across the three groups of Evaluation of Suicide Risk (ESR). These results supported the criterion-related validity of the scale. CONCLUSION: The findings in this study indicate that this scale is reliable and valid in assessing suicide risk of psychiatric inpatients. Therefore it is an appropriate scale to assess suicide risk for psychiatric inpatients.

Association between physical inactivity and academic record in korean adolescents

The purpose of this study was to investigate the association between physical inactivity and academic record in Korean adolescents. Adolescent students from the first grade of middle school to the third grade of high school [n=75,066] participated in the 5th Korea Youth Risk Behavior Web-based Survey project in 2009. The association between physical inactivity and academic record was assessed using multivariate logistic regression analysis after adjusting for gender, age, body mass index, family's socioeconomic status, parents' education level, and frequency of vigorous or moderate physical activity [PA] as well as muscular strength exercises. During weekdays, the odds ratios [Ors] [95% confidence interval [CI] for reporting a higher than average academic record, as compared with <1 hour of physical inactivity per day, was 0.796 [0.761-0.832, for >/= 1 to <2 hours, 0.632 [0.603-0.663, for >/= 2 to <3 hours, 0.567 [0.535-0.601 for >/= 3 to <4 hours, and 0.494 [0.468-0.522, P < 0.001 for all cases] for >/= 4 hours of physical inactivity per day. During the weekends, the ORs [95° o CI] for reporting a higher than average academic record, as compared with <1 hour of physical inactivity per day, were 0.901 [0.848-0.957, P = 0.001] for >/= 3 to <4 hours and 0.785 [0.743-0.830, P < 0.001] for >/= 4 hours of physical inactivity per day. Korean adolescents who spend more time engaged in physical inactivity are predisposed to a below-average academic record
