The purpose of this study is to test the reliability and validity test of PWI to utility of PWI. this newly developed by Sejin Jang which measures stress. The subject were 186 workers in service area. Cronbach's a and Guttman split-half coefficient is used to test the reliability of PWI. Factor analysis and the correlation of the GHQ-60. GHQ-30, GHQ-28, GHQ-20, and GHQ-12 with the PWI is used to convergent validity and discriminant validity. The important results of this study are as follows : Cronbach's $\alpha$ coefficient of data was 0.894 and Guttman split-half coefficient was 0.7097. The PWI was classified as 13 principle component (eigenvalue＞1.0). After exploring 4 factor structure according to previous study result, 4 factors was explained 40.5% out of the total variance. The factor 1 was explained 15.9% and then the rest three factor was 24.6%. Factor 2 and 4 showed good agreement but factor 1 and 3 did not. Depression-related items were classified two factors. Anxiety and depression-related items were loaded unifactor. It was not clear that the PWI was consist of 4 concepts(factors). The correlation of the GHQ-60, GHQ-30, GHQ-28, GHQ-20, and GHQ-12 with the PWI were 0.744~0.905. According to findings of this study. the PWI showed a high degree of validity and reliability. Thus it is recommended to use the PWI in general setting for screening for stress. In addition, it is necessary to clarify the concept of depression and anxiety. In the further study. it my be considered to the factor structure of PWI and studied to two or unidimensional factor structure.

This study investigated the stress of community residents in Kwang-Ju and Chonnam areas by using the General Health questionnaire(GHQ-60) as a instrument of stress measurement. The number of subjects were 445 residents who lived in three areas(large city, middle city, and rural area) and they were individually interviewed in March, 1994. The results of study showed that the degrees of stress measured by GHQ-60 were statistically significant in the residents' area, age, sex variables: (a) the residents in middle city among three areas had the highest level of stress; (b) the residents who were more than 60 in age had the highest level of stress: (c) the female residents had more stress than male residents, (d) particularly, the residents who were more than 60 years old in the middle city had the highest level of stress. Further, the results of factor analysis showed that there were three factors of social dysfunction, depression and anxiety and psychosomatic symptom. The social dysfunction factor was statistically significant in both age and resident area variables. The depression and anxiety factor was statistically significant in the residents' area, age, sex variables. The psychosomatic symptom factor was statistically significant in both age and sex variables. The study suggested that they should give a special attention to solve the old people's stress because stress was closely related to residents' age.

BACKGROUND/OBJECTIVES: Depression and anxiety are common mental health problems. Anthocyanins from berries might have an inhibitory effect on monoamine oxidase (MAO) enzymes and alleviate various mood and anxiety symptoms. This study examined the effects of a daily supplement of an anthocyanin-rich product on mental health problems. SUBJECTS/METHODS: This study was a secondary analysis from a randomized, 6-week, open-label trial in 300 healthy participants aged 18-60 years who consumed 1 or 2 servings of anthocyanin-rich mulberry milk daily. The General Health Questionnaire-28 (GHQ-28) and Hospital Anxiety and Depression Scale (HADS) were used to monitor mental health problems. In addition, the saliva activity levels of MAO-A, MAO-B, and cortisol were examined at the baseline and after 6 weeks. RESULTS: The total scores of the GHQ-28 and HADS and all their subscales decreased in both groups (all P < 0.05). The cortisol, MAO-A, and MAO-B activities decreased significantly (all P < 0.05), but there were no significant differences between the groups (all P > 0.05). Significant correlations were noted between the decreased activity level of MAO-A enzyme and decreased scores from the GHQ-28 somatic subscale and the HADS depression subscale (all P < 0.05). CONCLUSIONS: Daily consumption of anthocyanin-rich mulberry milk possibly improves mental health problems by reducing depressive and anxiety symptoms in the working population. The suppression of MAO-A activity is a possible underlying mechanism.

Objectives : This study evaluated the stress of community residents using the General Health Questionnaire, GHQ-60, as an instrument of stress measurement. Methods : The study included 2100 residents, aged 20 and over, living in three areas, a large city, a medium sized city and a rural area, between June and September 2001. A questionnaire interviewing method was used to collect data. The data were analyzed using a t-test, ANOVA, Pearson's correlation coefficients and multiple regression analysis. Results : In this study, the degree of stress, as measured by the GHQ-60, was shown to be significantly higher in the following categories: females, people over 60 years old, people engaged in the primary industries and labor work, low incomes, the divorced and the bereaved, people who received no more than an elementary education, people who suffer from chronic diseases and non-exercisers. A factor analysis suggested that there were three factors of social dysfunction factors; psychosomatic symptom, and depression and anxiety, The social dysfunction factors was statistically significant for the groups described above. The factor of psychosomatic symptoms was statistically significant in the rural residents, and in the groups describedabove. The depression and anxiety factor was statistically significant in the large city residents, people aged between 20-29 years, students, unmarried persons, university graduates and those having suffered from chronic diseases. From the multiple linear regression analyses, chronic disease, exercise, gender and income, proved to be significant stress related factors Conclusions : This study suggests that special attention should be given to the management of the chronic invalided, non-exercisers, females and snail income earners, in order to maintain and promote the psychological health of residents in a community.

Objective : Existing depression rating scales do not fully reflect depressed patients' perspective of remission, which goes beyond symptom resolution. The Remission from Depression Questionnaire (RDQ) captures a broader array of domains, and the present study examines the reliability and validity of the Korean Version of the RDQ (K-RDQ). Methods : The test-retest reliability of the K-RDQ was studied in 60 depressed patients and 30 normal subjects working at a university hospital. Subjects were evaluated at baseline and again 1-2 weeks later. The validity of the K-RDQ was studied in 200 depressed patients who were rated on the 17-item HDRS and the CGI-S ; each patient also completed the QIDS-SR, STAI-S, GHQ/QL-12, and SDS. Results : The K-RDQ demonstrated excellent internal consistency, with a Cronbach's ${\alpha}$ of 0.965 for the total scale and above 0.80 for each of the 7 subscales. The test-retest reliability of the total scale was 0.951. Mean K-RDQ scores ($45.79{\pm}18.65$) of the depressed patients were significantly higher than those ($15.87{\pm}10.60$) of the mentally healthy subjects (t=12.8, p<0.001). Five factors from the K-RDQ were extracted by principal axis factoring with equimax rotation. Conclusion : These results indicate that the K-RDQ is a reliable and valid measure that evaluates multiple domains that depressed patients consider important in determining remission. Thus, the K-RDQ maybe considered an appropriate tool for use in the clinical setting.
