Development and validation of a lung transplant-specific disability questionnaire

There are few instruments to assess patient-centered outcomes after lung transplant.  The authors developed and validated a shortened version of the valued life activities disability scale for this population.  The scale was devised using 140 lung transplant participants and was validated in 84 patients before and after transplant.  The instrument takes only 3 min to complete, has good correlation with longer scales, has good internal consistency, correlates with physiologic parameters, and demonstrates expected improvement comparing before and after transplant states.
