The reliability of the questionnaire was tested by split-half coefficient and Cronbach's alpha coefficient; the validity was tested by means of principal component factor analysis.
  
  
  RESULTS
  The self-reporting questionnaire and split-half coefficient was 0.748, each item of Cronbach's alpha in the reliability coefficient was between in 0.778 to 0.789, overall Cronbach's alpha in the reliability coefficient was 0.792. There were five main components in principal component factor analysis: lacking of power, somatization/biological symptoms, depression thought, emotions and awareness.
  
  
  CONCLUSIONS
