Validity and reliability of the thirst distress scale and the short version of the xerostomia inventory for use in German patients with chronic heart failure: A multicenter cross-sectional study
Background
Thirst and xerostomia are prevalent and distressing symptoms in patients with chronic heart failure (CHF). Evaluation of interventions to alleviate these symptoms requires valid and reliable instruments. Such instruments are currently lacking for German patients with CHF.
Objectives
The purpose of this study was to evaluate the structural and convergent validity, and internal consistency reliability of the German versions of the Thirst Distress Scale for Patients with Heart Failure (G-TDS-HF) and the short form of the Xerostomia Inventory (G-SXI).
Methods
A cross-sectional, multicenter study was conducted involving patients with CHF. Participants completed a questionnaire containing the G-TDS-HF, G-SXI, and a visual analog scale (VAS) to indicate intensity of thirst and xerostomia. Exploratory and confirmatory factor analyses were conducted to assess structural validity. To assess internal consistency reliability, McDonald's Omega total was calculated, and Pearson´s r was used to examine convergent validity.
Results
A total of 371 patients (62.4 (± 14.9) years, 28.3 % female) participated in the study. Factor analysis of the G-TDS-HF revealed a two-factor structure. One factor represents symptom occurrence, and the second factor is symptom distress. Internal consistency reliability was deemed adequate, with McDonald's Omega total coefficients of 0.81. The correlation between the sum scores of the G-TDS-HF and thirst intensity (VAS) was r = 0.44 (p < 0.001). The G-SXI demonstrated a single-factor structure with a McDonald's Omega total of 0.71. The correlation between the G-SXI and xerostomia intensity (VAS) was r = 0.36 (p < 0.001).
Conclusion
Results suggest that the G-TDS-HF and the G-SXI are valid and reliable instruments. Further research is warranted to assess responsiveness and test-retest reliability to strengthen the evidence.
期刊介绍：
Heart & Lung: The Journal of Cardiopulmonary and Acute Care, the official publication of The American Association of Heart Failure Nurses, presents original, peer-reviewed articles on techniques, advances, investigations, and observations related to the care of patients with acute and critical illness and patients with chronic cardiac or pulmonary disorders.
The Journal''s acute care articles focus on the care of hospitalized patients, including those in the critical and acute care settings. Because most patients who are hospitalized in acute and critical care settings have chronic conditions, we are also interested in the chronically critically ill, the care of patients with chronic cardiopulmonary disorders, their rehabilitation, and disease prevention. The Journal''s heart failure articles focus on all aspects of the care of patients with this condition. Manuscripts that are relevant to populations across the human lifespan are welcome.
