The Performance Measure for Activities of Daily Living-8 (PMADL-8) for patients with congestive heart failure is an International Classification of Functioning, Disability, and Health-based Activities of Daily Living (ICF) questionnaire to evaluate disease-specific functional limitations in chronic heart failure (CHF). The purpose of this study was to investigate the reliability and validity of the Turkish version of the PMADL-8 in CHF patients.In this study, 50 patients with CHF were included. Test-retest reliability of the PMADL-8 was assessed by intraclass correlation coefficient and Cronbach's alpha was calculated for internal consistency. Correlation coefficients between the PMADL-8 and New York Heart Association (NYHA) functional class, Chronic Heart Failure Questionnaire (CHQ), Nottingham Health Profile (NHP) were analyzed for construct validity.The Cronbach's alpha value of the PMADL-8 test and retest scores were recorded as 0.996, indicating that the scale is highly reliable. Test-retest reliability results of the PMADL-8 (mean intraclass correlation coefficient = 0.996) were excellent. The PMADL-8 score was moderately correlated with the NHP total score (r = 0.629, Plt; .001) and NHP physical abilities score (r = 0.517, Plt; .001). The PMADL-8 score was weakly correlated with the NYHA functional class (r = 0.385, Plt; .006), CHQ dyspnea (r = -0.475, Plt; .001), CHQ fatigue (r = -0.340, P = .016), and total score (r = -0.367, P = .009).The Turkish version of PMADL-8 is a reliable and valid assessment tool that could be used to determine activity limitations in CHF. The PMADL-8 is also useful for health professionals during the ICF evaluation of CHF patients. |
