The following questionnaire files contain graphics and therefore have been organized as downloadable '.pdf' files, and these can be viewed and printed with Adobe Acrobat.
If you use any of these questionnaires in your research we ask that you acknowledge the source of the instruments.
Scoring Guidelines - Cornell Hand Discomfort Questionnaires
These questionnaires are for research screening purposes and not for diagnostic purposes. Scores can be analyzed in 4 ways:
In the computational analyses missing values can be coded as 0. If the missing value is for the frequency score then use this as a zero in multiplying, i.e. all combinations of Frequency, Discomfort and Interference become 0. However, if the missing value is in the Discomfort or Frequency score then treat it as missing so that the multiplied score will be at least the value of the Frequency score.
The individual items should also be analyzed to determine where there may be a postural problem for the person.
Validity and Reliability
The validity of the CHDQ has been extensively tested by Dr. Oguzhan Erdinc in Turkey with good results.
