PURPOSE
This study was carried out to identify the factor of decisional balance for exercise. This was composed of a set of variables at the level of decision making when the elderly decide to do exercise. It was used to classify and identify the characteristics of the stages of change for exercise to which the elderly belong, and was used to identify the variables of decisional balance which influence the stage of change for exercise in the elderly.
METHODS
Convenient samples of 198 subjects over age 60 in Seoul( mean age=70) were selected from community living, mentally competant older adults and the data was collected from April 1, 1999 to May 31, 1999. The research instrument was the Decisional Balance Measure for Exercise(Marcus &Owen., 1992), Stage of Change Measure(Marcus et al,1992). The data was analyzed by SAS Program.
RESULTS
1. According to stage of change measure, without missing data,191 subjects were distributed in each stage of change for exercise: 50 subjects(26.1%), 7 subjects (3.6%), 52 subjects(27.2%), 4 subjects(2%), and 78(40.8%) belonged to the pre- contemplation stage, contemplation stage, preparation stage, action stage and maintenace stage. 2. Factor analysis identified 3 factors of decisional balance as appropriate factors for exercise of the elderly and named by researchers; 1)'Perceived Physical-psychological benefit', 2)'Perceived Physical-psychological burden', and 3)'Perceived time burden'. 3. The analysis of variance showed that the two components Perceived Physical - psychological benefit(F=45.95, P=.0001), and Perceived Physical-psychological burden (F=26.52, P=.0001) were significantly associated with stage of change. 4. Through the discriminant analysis, it was found that both 'Self Perceived Physical - Psychological benefit' and 'Perceived Physical-Psychological burden' were the influential variables in discriminating the three stages of change(pre-contemplation, preparation, and maintenance).
CONCLUSION
Results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behaviors. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for exercise intervention about especially the factors relating to decision making for exercise of the elderly in the different stages of change of exercise.

This study attempted to investigate the relation of perceived health influencing factors, health practice performance and perceived health status in the elderly. The subjects of the study were 95 elderly people over the age of 60, living in Seoul and Kyungi province area in Korea. They were conveniently sampled for this study and the data was collected from March, 1998 through August, 1998. The instruments for this study, which were for measuring perceived health influencing factors and health practice performance, were developed by the researchers. The instrument for measuring perceived health status were items from the OARS Multidimensional Functional Assessment Questionnaire(OMFAQ). The data was analyzed using descriptive statistics. Pearson's Correlation Coefficients and Stepwise Multiple Regression. The results of this study are as follows: 1. Influencing factors were divided into 3 perceived health enhancing factors and 3 perceived health hindering factors and health practice was divided into 4 health practice factors. 2. Health practice factor which was characterized as 'taking regularly vitamin, nutrient, oriental medical herbs and doing passive exercise' performance showed significant posisitive correlation with both perceived health enhancing factors which were 'empathetic support' and 'health maintenance through medical regimen'. Health practice factor which was characterized as' self monitoring through medical regimen' performance showed significant positive correlation with perceived health enhancing factor 'health maintenance through medical regimen'. Health practice factor which was characterized as 'actively taking food or nutrients which are recognized as good for health in public' performance showed significant positive correlation with both perceived health enhancing factor 'health maintenance through medical regimen' and perceived health hindering factor 'inappropriate health management'. 3. Stepwise Multiple Regression analysis revealed that: The Statistically significant influencing variables of perceived health status were health practice factor 'actively taking food or nutrients which are recognized as good for health in public' performance and perceived health enhancing factor 'empathetic support'.
