Abstract
This study was conducted to test the psychometric properties of a newly developed health-related quality of life (HRQOL) questionnaire. One hundred eleven individuals identified through a registry and medical records who experienced an acute iliofemoral deep vein thrombosis (DVT) more than six months ago completed the questionnaire (containing the Health Utilities Index and Short Form-12, and DVT-specific scales). Respondents were primarily female, Caucasian, and married with an average age of 54 years. Internal-consistency reliability was acceptable (Cronbach's alpha: 0.69–0.95). Interscale correlations were as expected. In general, patients with no symptoms reported the highest functioning, those with severe symptoms the lowest, and those with moderate symptoms reported values between the two. Guyatt's statistic values for the majority of scales were ≥|0.20|, demonstrating acceptable responsiveness to change. Psychometric testing indicated that the measure is reliable, valid, and responsive in this group. Future research will focus on further evaluating its use in studies of patients receiving different therapies for acute DVT.
