A preference-based measure of health: the VR-6D derived from the veterans RAND 12-Item Health Survey

Abstract

This study produced a utility measure for the VR-12 that is comparable to the SF-6D and responsive to change. The VR-6D can be used in evaluations of health care plans and cost-effectiveness analysis to compare the health gains that health care interventions can achieve.

Comparison of health utility weights among elderly patients receiving breast-conserving surgery plus hormonal therapy with or without radiotherapy

“…We used a novel multi-stage mapping algorithm to convert VR-12 into VR-6D 13 for the radiation therapy and no radiation therapy groups. The multi-stage mapping approach involves the use of different health-related quality of life (HRQOL) questionnaires (SF-36, VR-36 and VR-12) to derive preference-based measures (SF-6D and VR-6D).…”

“…The six dimensions are physical working, part restrictions, social working, agony, psychological well-being, and imperativeness 13 .…”

“…The VR-6D, a preference-based measure derived from the VR-12, has comparable distributional properties to the SF-6D 13 . The VR-6D represents health utility scores ranging between 0 and 1, 0 representing death and 1 representing optimal health 13 .…”

“…The VR-6D represents health utility scores ranging between 0 and 1, 0 representing death and 1 representing optimal health 13 . The multi-stage mapping algorithm operates as follows 13 : Step 1: The prediction of SF-6D scores from responses to VR-36 questionnaire using the coefficient of the regression of the Brazier’s SF-6D scores onto the SF-36 questionnaire. Step 2: The predicted SF-6D scores from responses to VR-36 were compared to the Brazier’s SF-6D scores. Some adjustments were made for the SF-6D scores from VR-36 to have a maximum utility value of 1.…”

Short Form health surveys and related variants in spinal cord injury research: A systematic review

“…The 'Family' of Short Form health surveys [17][18][19] It is important to note that 'Short Form', when used in this paper, refers only to health surveys that can be traced back to the Medical Outcomes Study and, therefore, does not refer to any and all short form instruments in the health outcomes literature. Also, 'health survey' is a term that has become synonymous with outcome measures emerging from the Medical Outcome Study.…”
