[Structural equation model for the health behaviors of university students in Korea].

PURPOSE: A structural equation model was analysed to explore the determinants of health behaviors of university students in Korea. METHOD: Nine hundred sixty nine university students were selected by random cluster sampling from five universities located in the central area of Korea. DATA COLLECTION: The data was collected by questionnaires about demographic characteristics, stressful life events, perceived social support, perceived health status and health behaviors. RESULTS: 1. Gender showed indirect effect on health behaviors. 2. Living together with(out) family had a direct effect on health behaviors: students living with family showed more positive health behaviors. 3. Stressful life events had an indirect effect on health behaviors via perceived health status; a higher score of stressful life events was the predictor for negative health behaviors. 4. A higher score of perceived health status predicted positive health behaviors. RECOMMENDATION: Each university should be encouraged to develop a health behavior control program and health promotion program for their own university students. It would be more effective to develop health programs separately according to the demographic or social characteristics of the students. It is also necessary for the Ministry of Education to reform the School Health Act and school health policy to strengthen a health promotion program for university students. In conclusion, following studies should identify and promote the validity and reliability of perceived health status and health behaviors measurements.

[Quality of life in low income Korean aged].

PURPOSE: The purpose of this study was to identify the quality of life and its predictors in low income Korean aged. METHODS: This was a predictive correlational study. An accessible sample from the population of people who were 65 and over and were supported by the basic livelihood security system was 1,040. Quota sampling with strata of state division in the nation was chosen. Quality of life and its predictors in the subjects were measured. RESULTS: The mean quality of life in the subjects was 47.0+/-10.7. Predictors of this study significantly explained 54.3% of the total variance of quality of life. Depression was the most significant predictor of quality of life. Health problems, district, social support, leisure activity, and health behavior had effects on quality of life. CONCLUSION: This finding indicates that quality of life in lower income Korean aged is different from other populations by economic status. Demographics, health status and social status were predictors of quality of life in the aged with a small income.

[Psychometric evaluation of the Korean social support questionnaire].

PURPOSE: Research related to social support in Korea has been hampered by paucity of measurement tools reflecting Korean culture. The aim of the study was to develop Korean social support questionnaire (KSSQ) based on the Korean social support pyramid and to test psychometric properties of the KSSQ. METHODS: The questionnaire was administered to 701 subjects and 658 college students. Psychometric analyses included factor analyses, expert validity, criterion-related validity, internal consistency, and test-retest reliability. RESULTS: A principal components analysis support for construct validity, eliciting a three factor solution accounting for 65.46% of variance in scores. Concurrent and discriminant validity supported criterion-related validity. Internal consistency of reliability was support with Cronbach's alpha of .97-.98 for the entire scale. Test-retest reliability was .76. CONCLUSION: This initial testing of KSSQ to measure Korean social support demonstrates evidence of reliability and validity. Assessment of known-group validity and norm establishment of KSSQ are suggested to provide further sound psychometric properties and practical measurement tools.
