    Scale development study: The Fluid Control in Hemodialysis Patients
    (Blackwell Publishing Asia, 2016) Albayrak Cosar A.; Cinar Pakyuz S.
    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.

    A scale development study: Hemodialysis comfort scale version II
    (SAGE Publications Ltd, 2022) Kosar Sahin C.; Cinar Pakyuz S.
    Aim: Aim of this study was to develop a valid and reliable measuring tool in order to evaluate comfort of patients receiving hemodialysis treatment. Background: There has been available a scale developed to evaluate comfort of hemodialysis patients “HDCS (Hemodialysis Comfort Scale).” Due to HDCS consisted of nine items and evaluated comfort in two sub-dimensions, researchers who developed HDCS, stated that number of scale items and dimensions is not sufficient to fully evaluate comfort. Therefore, (Hemodialysis Comfort Scale Version II) HDCS-II was developed with this research and its development process were discussed in this article. Materials and Methods: Sample of this methodological research was consisted of 436 chronic hemodialysis patients, treated at five hemodialysis centers between October 2018 and May 2019. In process of creation item pool, comfort theory and literature was examined. The items in the old scale were also revised and included. Thereby a new question pool of 87 items was created. This draft scale was sent for expert opinion. In validity of scale; content validity index, exploratory and confirmatory factor analysis were used. In reliability study; Item analysis, cronbach’s alpha reliability coefficient, parallel form reliability and item analysis based on upper-lower group averages were used. Results: There was consistency between expert views relating to items in scale. According to exploratory factor analysis, scale consisted of six dimensions. Cronbach alpha coefficient of 26-item scale was 0.79. Alpha values of the six factor in scale were, respectively; for physical relief 0.83, for physical ease 0.71, for psychospiritual ease 0.87, for psychospiritual transcendence 0.85, for environmental transcendence 0.82, and for sociocultural ease 0.61. Conclusion: HDCS-II is a 5-point likert type and consists of 26 items and 6 factors. This scale is a valid and reliable measurement tool that can be used to determine comfort of patients undergoing hemodialysis treatment. © The Author(s) 2021.
