  Dear all,

  Unbelievable comments from reviewers of a research grant review board:

  "The questionnaire should be shortened. The proposed validation analysis (using Rasch modelling) is not appropriate for a questionnaire focusing on attitude and behaviour and should be revised."

  "The methods proposed for the adpatation of the content of the IMAQ (the questionnaire) are well written, but Rasch analysis for the valdiation/reduction of items is not appropriate because the items on attitude or usage do not have a linear order, unlike educational assessment. More standard methods, such as know group comparison or concurrent validity, for validating the construct/criterion validity of the IMAQ should be used."

  Any comments?
