Objective: To explore the psychometric properties of the Subjective Happiness Scale (SHS) in patients with Chronic Kidney Disease (CKD) undergoing hemodialysis. Methods: This is a methodological study. The random sample included 171 patients with CKD under hemodialysis program in two clinics in the region of Lisbon, Portugal. Data was collected between May and June 2015. The following psychometric properties were evaluated: validity (construct, convergent and discriminant), reliability through internal consistency (Cronbach α) and stability (intraclass correlation coefficient and Spearman-Brown correlation coefficient). Results: The results support the unifactorial structure, with reliability (α = 0.90). In addition, this scale is positively correlated with the Satisfaction Life Scale (r = 0.60; p <0.001), supporting the validity criteria. Conclusions: The Portuguese version of the SHS is valid and reproducible in patients with CKD. [ABSTRACT FROM AUTHOR]

Objective: Verify the psychometric properties of the Portuguese version of the Brief Pain Inventory in persons with chronic kidney disease who are undergoing hemodialysis. Method: This is a methodological study. The selected sample is comprised of 171 persons with chronic kidney disease who experience pain for at least 24 hours and are undergoing hemodialysis at two clinics in Lisbon, Portugal. The data were collected between May and June 2015. The psychometric properties that were evaluated include validity (construct, convergent and discriminant), reliability (Cronbach's α) and stability (test-retest). Results: Information was obtained that adequately supports a bi-factor structure (pain interference and degree of pain severity), with reliability (α = 0.90 and α = 0.80, respectively) and stability. The measures registered correlate positively with the negative effect, and negatively, with measures of quality of life, which support concurrent validity. The existence of support for predictive validity was verified. Conclusions: The "pain severity" and "pain interference" measures obtained with the Brief Pain Inventory are valid and reproducible in persons with chronic kidney disease who experienced pain during the 24 hours before the questionnaire was used and the interview was conducted.
