Attitude scale for the dietary therapy of hemodialysis patients: Turkish validity and reliability study

The present study aims at the adaptation of "Attitude Scale for the Dietary Therapy of Hemodialysis Patients" (ASDTHP) into Turkish language with a validity and reliability study.

Methodological design was used in the study which included 200 patients receiving treatment in the dialysis unit of a university and a state hospital in Turkey from April 2019 to October 2019.

As a result of the assessments and analyses conducted, content validity of the scale was found as 0.98. Total Cronbach's coefficient of the scale was 0.84, while Cronbach's coefficient was 0.91 for propensity of behavior that is affected by cognition, 0.91 for propensity of behavior that is affected by diet and 0.87 for negative effect that modifies the diet. Item factor loads were found to differ between 0.73 and 0.89 and item total correlation coefficients were found to be between 0.38 and 0.53. It was found that Turkish version of the Attitude Scale for the Dietary Therapy of Hemodialysis Patients also had three sub-dimensions like the original scale.

Turkish version of ASDTHP is a valid and reliable measurement instrument to evaluate the attitudes of hemodialysis patients about dietary therapy. ASDTHP can help nurses in finding out hemodialysis patients' lack of knowledge and skills and negative attitudes about diet therapy.
