Comparative Study
A comparison of the discriminative and evaluative properties of the SF-36 and the SF-6D index.
To examine whether the move from the multidimensional SF-36 patient-reported outcome measure to the single-index preference-based SF-6D entails a loss in discriminative and evaluative properties, the magnitude of that loss and whether it matters. ⋯ No scale/dimension consistently had the largest RV, ES, or SRM across all conditions studied. Moving from the SF-36 to SF-6D entails losses of a small magnitude in discriminative and evaluative properties.

To compare the psychometric properties of the Hughston Clinic Questionnaire (HCQ), EQ-5D and SF-6D in patients following arthroscopic partial meniscectomy surgery. ⋯ For this patient population, our findings indicated that the EQ-5D was more consistently responsive to change over time, as a utility index was better at distinguishing differences between groups and reflected the results of the joint-specific HCQ for knee recovery better than the SF-6D. It is therefore recommended that for similar populations, the EQ-5D is preferable to the SF-6D for utilisation alongside the HCQ.
