Wilawan Phukamung.  1996.  Variables Relation to Behavior of Junior Health Workers in Promoting
Medicinal Plants in Kalasin Provice.  Dissertation, M.S. (Behavioral Science) Behavioral Science Research
Institute. 


           This research had two objectives : 1) to compare the promoting behavior in medicinal plants of junior
health workers relating to psycological traits and bio-social characteristics  2) to search for important predictors
which can predict promoting  behavior 
in medicinal plants. 
            The sample of this study was the male and female health workers of Karasin provice who work at the
Health Centre in 1995 of 308 persons as the whole population. 
           This was a field study Data was collected by using the questioniare which were divided into three
parts. The first part was The questionaire about the bio-social background which included sex, age, income, work
experience and the information gained about the medicinal plants. The second part consisted of 4 questionaire; the
promoting medicinal plants traits inventory, the attitude toward promoting behavior of medicinal plants inventory,
the social support inventory, the role ambiguity inventory. The third part was the questionaire of motivational
inventory. 
             The analysis of this study was two-way analysis of variance and multiple regression analysis. 
              The findings of this study were : 
              1.  From the comparison of the promoting behavior in medicinal plants about psychological traits and
bio-social characteristics the results were : 
                    1.1  There was no interaction effect between sex and information gained about the medicinal plants but
it was found that the junoir health workers who recieved more information about medicinal plants showed  higher
promoting behavior in medicinal plants than those who recived less information about the medicinal plants. 
                    1.2  There was interaction effect between the motivation and role ambiguity. It was found that the junior
helth workers who had high motivation and low role ambiguity showed higher promoting behavior in medicinal
plants than those who had high role ambiguity, the junior helth workers who had low role ambiguity and high
motivation showed higher promoting behavior in medicinal plants than those who had low motivation and the junior
health workers who showed low motivation and low role ambiguity was higher promoting behavior in medicinal
plants than those who was high role ambiguity. 
                    1.3  There was no interaction effect between attitude toward promoting behavior in medicinal plants and

                    1.5  There was interaction effect between age and duration of work. It was found that the junior health
workers who had higher age and low duration of work showed higher promoting behavior in medicinal plants than
theose who had high duration of works and the junior health worker who had higher age showed higher promoting
behavior in medicinal plants than theose who were younger. 
                2.  When searching for important predictors which can predict promoting behavior in medicinal plants. 
                    2.1  The Expectancy could explain 5.80% of the variance in pomoting behavior in medicinal plants. 
                    2.2  The social support, information gained about medicinal plants and role ambiguity, as a whole could
explain 33.42%  of the the variance for the promoting behavior in medicinal plants.
