Care action and Rehabilitation  action.                  Descriptive  statistics, Two-way Analysis of  Variance  and Multiple Regression Analysis were used to analyze the whole group data and 5 background  characteristic  groups data.               The reseach finding were  as  follows:                   1.  Concerning  the  different aspects of Professional-role  action                 1.1  For Professional-role action, it was found that Professional-role identity and Professional sociatization  with health  tearn  could predict 22-08 %  of  variance in Professional-role action.  The most  important predictor  for  4  groups was  Profession-role identity                 1.2  For Preventive action and Encourage action, the result showed that Professional socialization with nursing team and Ittibaht  4  could pedict  13.88  % of variance in Preventive action and 13.21 %  of variance in Encourage action. Professional socialiation or Ittibaht  4  was the most important predictor for 2 groups.                  1.3  For Care action and Rehavilitation action:  Professional-role identity, Professional socialization with nursing team, and Professional socializational with health teamcould predict  15.71%  of variance in Care action and 16.04% of variance in Rehavilitation action.  It was also found that Profesional-role identity or Ittibaht  4  was the most important predictor                 2.  Professional-role actions were in the high level for all groups.
