The AIMS2 subscales (physical function, pain, psychological function and social interaction) were slightly more responsive than those of SF-36. The physical and pain dimensions were most sensitive for measuring change over a 12-month period, followed by psychological and social dimensions. For the utility measurement, RS scores were found to be significantly more responsive in detecting changes in preferences than TTO scores.
