A brief description of the initially reported psychometric properties of the measure.
A study comparing the SF-36 with MYMOP found that the index of responsiveness, relating to the minimal clinically important difference, was high for MYMOP: 1.14 for the first symptom, 1.33 for activity, and 0.85 for the profile compared with <0.45 for SF-36. They reported that MYMOP's validity was supported by significant correlation between the change score and the change in the MYMOP score and the ability of this instrument to detect more improvement in acute than in chronic conditions. The findings also showed that MYMOP was more sensitive to change than the SF-36. The authors highlight that MYMOP has the advantage that it can also improve patient-practitioner communication (Paterson, 1997). There has alos been a qualitative evulation of MYMOP (Paterson & Britten, 2000).
