A factor analysis and correk lion test for the statistical validity of the variables in the evaluation tool, a Chronbach´s Alpha value for the reliability in the evaluation indices and a regression analysis for the relations of the evaluation model were performed.
The results were as follows:
1. In ´factor analysis, thirty-three variables among 43 variables were selected as significant variables, ie 9 out of 11 for input index, 11 out of 14 for throughout index and 13 out of 18 for out put index.
2. Three evaluation(outcome) scales(evaluation by employer, health manager and employee) which composed of 16 identical items were used.
3. The Chronbach´s Alpha values of input, throughout, out put and outxne indices were 05221, 0.5473, 0.7122 and 0.8546 _respectively.
