Abstract

Aim: The aim of this study was to develop a valid and reliable measurement instrument to identify knowledge, behaviors, and attitudes of hemodialysis (HD) patients about fluid control as these patients are inadequate in ensuring and sustaining fluid control. Methods: The sample of this methodological study consisted of 276 HD patients who are being treated in two public and two private hemodialysis centers. The validity of the scale was assessed through content validity, construct validity, and similar scale validity, and its reliability through item analysis, internal consistency coefficient and test-retest. For the content validity of the scale, expert views were assessed, and opinions of a Turkish language specialist were obtained. Results: According to the exploratory factor analysis, the scale had 24 items and three subdimensions, namely, knowledge, behavior, and attitude. The total variance explained was found to be 51.15%. Cronbach's alpha reliability coefficient of the Fluid Control in Hemodialysis Patients Scale (FCHPS) turned out to be 0.88 and Cronbach's alpha for its subdimensions were 0.92, 0.80, and 0.67, respectively. The correlation value between test and retest was 0.94 (P<0.001). A moderate significant correlation (r=0.58, P<0.001) was found between the scale scores and the scores of the Dialysis Diet and Fluid Restrictions Non-adherence Questionnaire. Conclusion: The FCHPS that was developed has good validity and reliability. This scale can be used to measure knowledge, behavior, and attitude of hemodialysis patients about fluid restriction. © 2016 Japan Academy of Nursing Science.
