Background Patients subjective impression of change is an important construct to measure following physiotherapy, but little evidence exists about the best type of measure to use. Objective To compare the construct validity and utility of two forms of a global subjective outcome scale (GSOS) in patients with back pain: Likert and visual analogue scale (VAS) GSOS. Design Two samples of patients attending physiotherapy for back pain completed a questionnaire battery at discharge from physiotherapy including either a Likert or VAS GSOS. Participants One hundred and eighty-seven {79 males, mean age 52.1 [standard deviation (SD) 15.5] years} patients completed the Likert GSOS and a separate sample of 144 patients [62 males, mean age 55.7 (SD 15.9) years] completed the VAS GSOS upon discharge from physiotherapy. Main comparisons The two versions of the GSOS were compared using pre- and post-treatment changes in scores using a VAS (pain), RolandMorris Disability Questionnaire (18-item version) and catastrophising subscale of the Coping Strategies Questionnaire 24. Results Both versions of the GSOS showed significant (P Conclusions The two versions of the GSOS showed similar validity; however, use of the Likert GSOS is recommended because of its greater utility. |
