Background: Patients with heart failure can experience thirst distress. However, there is no instrument to measure this in patients with heart failure. The aim of the present study was to develop the Thirst Distress Scale for patients with Heart Failure (TDS-HF) and to evaluate psychometric properties of the scale. Methods and results: The TDS-HF was developed to measure thirst distress in patients with heart failure. Face and content validity was confirmed using expert panels including patients and healthcare professionals. Data on the TDS-HF was collected from patients with heart failure at outpatient heart failure clinics and hospitals in Sweden, the Netherlands and Japan. Psychometric properties were evaluated using data from 256 heart failure patients (age 72±11 years). Concurrent validity of the scale was assessed using a thirst intensity visual analogue scale. Patients did not have any difficulties answering the questions, and time taken to answer the questions was about five minutes. Factor analysis of the scale showed one factor. After psychometric testing, one item was deleted. For the eight item TDS-HF, a single factor explained 61% of the variance and Cronbach’s alpha was 0.90. The eight item TDS-HF was significantly associated with the thirst intensity score (r=0.55, p<0.001). Regarding test-retest reliability, the intraclass correlation coefficient was 0.88, and the weighted kappa values ranged from 0.29–0.60. Conclusion: The eight-item TDS-HF is valid and reliable for measuring thirst distress in patients with heart failure. [ABSTRACT FROM AUTHOR]

Journal of Advanced Nursing 68(10), 2341-2348. Abstract Aim. To report a study conducted to compare the utility of the Care Dependency Scale across four countries. Background. The Care Dependency Scale provides a framework for assessing the needs of institutionalized patients for nursing care. Henderson's components of nursing care have been used to specify the variable aspects of the concept of care dependency and to develop the Care Dependency Scale items. Design. The study used a cross-cultural survey design. Method. Patients were recruited from four different countries: Japan, The Netherlands, Poland and Turkey. In each of the participating countries, basic human needs were assessed by nurses using a translated version of the original Dutch Care Dependency Scale. Psychometric properties in terms of reliability and validity of the Care Dependency Scale have been assessed using Cronbach's alpha, Guttman's Lambda-2, inter-item correlation and principal components analysis. Data were collected in 2008 and 2009. Results. High internal consistency values were demonstrated. Principal component analysis confirmed the one-factor model reported in earlier studies. Conclusion. Outcomes confirm Henderson's idea that human needs are fundamental appearing in every patient-nurse relationship, independent of the patient's age, the type of care setting and/or cultural background. The psychometric characteristics of the Care Dependency Scale make this instrument very useful for comparative research across countries. [ABSTRACT FROM AUTHOR]
