ABSTRACT
PURPOSE:
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).METHODS:
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).RESULTS:
A total of 213 participants had complete datasets and were included in further analyses. Factor analysis with varimax rotation yielded six factors explaining 71% of the cumulative variance. Cronbach's alpha coefficient was found to be 0.94, indicating a very good intercorrelation of items. Of the 213 participants, 145 (68%) completed the questionnaire a second time. The ICC ranged from 0.75 to 0.86, indicating good test-retest reliability. All factors were found significant with p values <0.001. The criterion validity of the PEmb-QoL was confirmed through good correlation with other similar health-related quality-of-life constructs in the EQ-5D.CONCLUSIONS:
Findings of the current study indicate that Norwegian version of the PEmb-QoL is both valid and reliable, thus representing an important supplement in subjective outcomes measurement among patients sustaining PE.
