A standardised form was developed to review the daily problems suffered by patients with arthritis of the hip and provide clinicians with information for planning treatment and in judging subsequent progress. The reports made by various patients in a preliminary study provided 81 statements on pain, restricted movements, and restricted activities that were then tested to identify the most reliable. The responses of 32 patients waiting for hip replacements and 66 patients who had undergone operation were compared with independent assessments of pain and physical limitations. The 33 statements eventually selected were chosen mainly on the basis of their sensitivity to differences between preoperative and postoperative patients and their correlation with the independent assessments. The final questionnaire provides a valid and concise summary of a patient's disabilities and is simple enough for the patient to complete while waiting to see the doctor.
