The aim of the current study was to translate and test the psychometrical properties of the disease-specific pulmonary embolism quality-of-life questionnaire (PEmb-QoL). Patients with a prior history of pulmonary embolism (PE) were identified from the thrombosis registry at Østfold Hospital Trust, Fredrikstad, Norway. All eligible patients were asked to complete the generic EuroQol 5-dimension (EQ-5D) QoL questionnaire as well as the disease-specific PEmb-QoL at baseline and after 2 weeks. Construct validity was tested using principal component factor analysis. Criterion validity was tested using Spearman's correlation coefficients (rho) between EQ-5D and PEmb-QoL. Internal consistency reliability was calculated using Cronbach's alpha coefficient, while test-retest reliability was calculated using the intra-class correlation coefficients (ICC). A total of 213 participants had complete datasets and were included in further analyses. Factor analysis with varimax rotation yield...
