The purpose of this study was to investigate the actual status of Internet gaming disorder in university students, the relationship between perceived stress, social support, lifestyle and Internet gaming disorder, and the medium effect of social support in the relationship between perceived stress and Internet gaming disorder. The main results of the survey and analysis of 1,154 university students located in Gyeonggi Province are as follows. First, the prevalence of Internet gaming disorder among university students was 14.0 percent, which is very high. Second, the perceived stress had a positive correlation with the Internet gaming disorder. The more negatively perceived stress events occurred by university students, the higher the degree of internet gaming disorder was. Third, social support had a negative correlation with perceived stress and internet gaming disorder. The higher the support of parents, friends, and others, the lower the perceived stress and the lower the internet gaming disorder. Fourth, social support partially mediated the relationship between perceived stress and Internet gaming disorder. Even though stress was negatively perceived, the degree of internet gaming disorder was low when social support was high. Fifth, among the lifestyle habits of students, the rate of alcoholism was higher in the Internet gaming disorder group than in the non-disorder group. Finally, the results of the study and ways to prevent Internet gaming disorder among university students were discussed.

Background: The ongoing economic crisis in Greece has affected both stress and quality of life (QoL) at all socioeconomic levels, including professionals in the police force. The aim of this study was to examine perceived stress, job satisfaction, QoL, and their relationships in a sample of police officers in Greece. Methods: A cross-sectional study was conducted during the first trimester of 2011 in 23 police stations in the greater Athens area. A total of 201 police officers agreed to participate (response rate 44.6%). The General Health Questionnaire-28 (GHQ-28) was used to assess general health, and the World Health Organization Quality of Life-BREF Questionnaire and Perceived Stress Scale-14 (PSS-14) questionnaires were used to assess QoL and perceived stress, respectively. Results: The PSS and GHQ subscales and total scores exhibited strong, positive, and significant correlations coefficients (r): 0.52 for somatic disturbances, 0.56 for stress and insomnia, 0.40 for social dysfunction, and 0.37 for depression, yielding an r equal to 0.57 for the total GHQ score. A higher level of perceived stress was related to a lower likelihood of being satisfied with their job; in this regard, male participants and higher ranked officers reported lower job satisfaction. The PSS and GHQ scores were inversely, consistently, and significantly related to almost all of the QoL aspects, explaining up to 34% of their variability. Parenthood had a positive effect on QoL related to physical health, and women reported lower QoL related to psychological health. Conclusion: Higher levels of stress are related to an increased risk of reporting suboptimal job satisfaction and QoL. The magnitude of these associations varied depending on age, gender, and rank, highlighting the need for stress-management training.

This study was to identify the levels of perceived stress, immunity cells, physical health and depression, and their relationships among those variables in the elderly who institutionalized comparing home residents. The result of this study can be used as basic data when applying nursing interventions to increase quality of life in the elderly. The questionnaires to estimate stress, health status and depression were collected through direct interview from July to August in 1999 and immunity cells were measured by venous blood specimen collected from 9 to 10 A.M. during the same period. The collected data were analysed using SAS program. The results were as follows. The score of perceived stress of all subjects was 38.49 and perceived stress score of institutionalized elderly(42.62) was significantly higher than that in home resident elderly(34.52). All immune cells tested in this study such as total T cell, helper T cell, suppressor T cell, T4/T8 ration, total B cell, and NK cell, were all under the standard criteria of cells distributions. Most elderly who institutionalized and reside home replied that their health status was not good. However their physical health activity was mostly good even though institutionalized elderly had more disability than home residents. The highest rate was 67.3% as disability due to arthritis. The score of depression in all subjects was 8.2 that indicated having depressive symptom. There was no difference in the depression level between institutionalized elderly and home resided elderly. There was a significant correlationship between physical health and depression, however, the rest of varibles did not show any significant relationships. In summary, the immune cells in the elderly who replied perceiving low level stress, was under normal range. Their health status was perceived as 'not good' but physical health activity was perceived as 'good'. The relationships of stress, immunity, physical health and depression were partially significant but not had evidence as enough as theoretically the suggested relationship. We suggest that further studies using large sample size and more diverse variables should be performed.

Purpose: The purpose of this study was to examine the effects of aroma-necklace application on perceived stress, symptoms of stress and changes in autonomic nervous system among nursing students in clinical training. Methods: A research design for this study was a non-equivalent control group, non-synchronized pre-post test. The experimental group (n=39) underwent aroma inhalation by necklace which contains an essential oil mixture of lavender and sweet orange mixture in ratio of 2:1 for 2 weeks while the control group (n=36) received placebo therapy. The data were collected using self-administered questionnaires and measurement of heart rate variability (HRV) and analyzed using the PASW 18.0 program. Results: The perceived stress scores and scores of peripheral manifestations in the experimental group were significantly lower than those of the control group. All indices of HRV were significantly different between the two groups. LF norm and LF/HF ratio in the experimental group were significantly lower than those of the control group, and HF norm in the experimental group was significantly higher than that in the control group. Conclusion: It can be suggested that aroma-necklace application was effective in decreasing perceived stress and peripheral manifestations of stress and in changing HRV indices among nursing students in clinical training.

The purpose of this study was to investigate the short-term effects of electrical massager on stress-related parameters including heart rate variability (HRV), heart rate (HR) using the photoplethysmogram (PPG) signal with motion artifact correction. Twenty healthy subjects were randomly allocated to receive a 15-min section of three types ((1) resting mode (control group), (2) light massage mode, (3) strong massage mode). Results indicated that self-report, VAS (Visual Analog Scale) significantly decreased for two massage modes after massage except control group. In strong massage mode, it was associated with significant increases in HF, but significant decreases in LF and LH/HF ratio compared with the light massage mode. For all outcomes, similar changes were not observed in the control group. Also, the result founded that mean HR of all groups decrease. We conclude that electrical massager reduces perceived stress and improves adaptive autonomic response to stress in healthy adults.

The suicide rate in the elderly is continually increasing. Effective suicide prevention requires that factors affecting suicidal ideation are specifically identified and personalized intervention programs are developed. This study aimed to identify the influencing factors of suicidal ideation in Korean elderly. The data of the 2012 Korean National Health & Nutrition Examination Survey was analyzed by using the SPSS program. Frequency, percentile, Chi-square test, multiple logistic regression were used. The influencing factors of suicidal ideation were education, income, exercise, perceived stress and depression. The Odds Ratio of the depression was 5.68 and the Odds Ratio of the perceived stress was 3.45. This study suggested that elderly suicidal prevention programs should be developed in preventing and reducing stress and depression.
