Validation tests were within the accepted values in theliterature, therefore the questionnaire can be used on population scale in clinical practice,butalso in research.
Conclusion
By 7 days readministration of the questionnaire, for the study patients, resulted in no significant differences between the results. The kappa coefficient which validates the “test-retest” method for all domains of the questionnaire shows above 0.75 values. The Cronbach alpha coefficient which assesses internal confidence of the survey reached a value of 0.675 .
