Scale development of transformation from health technology assessment to policy-making / 中国卫生政策研究

ABSTRACT

Through literature review and theoretical analysis,an initial scale was designed with five dimensions namely"evidence influence","organizational support","channel connectivity","communication and collabora-tion"and"decision-makers impetus". The reliability and validity of the scale were evaluated through questionnaire survey on HTA researchers. It is reported that the overall Cronbach's α coefficient of the questionnaire was 0.904, meanwhile the Cronbach's α coefficient of each dimension was more than 0.80 except the dimension of"decision-makers impetus". The average variance extraction of each dimension was more than 0.50. The maximum of correla-tion coefficients between each dimension was 0.571,which was less than the threshold value of 0.85. Additionally, for certain dimensions,the standardized correlation coefficients to each other dimensions was less than regarding arith-metic square root of average variance extraction.
