We developed a 12-item questionnaire for completion by patients having shoulder operations other than stabilisation. A prospective study of 111 patients was undertaken before operation and at follow-up six months later. Each patient completed the new questionnaire and the SF36 form. Some filled in the Stanford Health Assessment Questionnaire (HAQ). An orthopaedic surgeon assessed the Constant shoulder score. The single score derived from the questionnaire had a high internal consistency. Reproducibility, examined by test-retest reliability, was found to be satisfactory. The validity of the questionnaire was established by obtaining significant correlations in the expected direction with the Constant score and the relevant scales of the SF36 and the HAQ. Sensitivity to change was assessed by analysing the differences between the preoperative scores and those at follow-up. Changes in scores were compared with the patients' responses to postoperative questions about their condition. The standardised effect size for the new questionnaire compared favourably with that for the SF36 and the HAQ. The new questionnaire was the most efficient in distinguishing patients who said that their shoulder was much better from all other patients. The shoulder questionnaire provides a measure of outcome for shoulder operations which is short, practical, reliable, valid and sensitive to clinically important changes.
我们设计了一份包含12个条目的问卷，供接受除稳定手术之外的肩部手术的患者填写。对111名患者进行了一项前瞻性研究，在手术前及术后6个月的随访时进行。每位患者都填写了这份新问卷和SF36表格。一些患者还填写了斯坦福健康评估问卷（HAQ）。一名骨科医生评估了康斯坦特肩部评分。问卷得出的单一分数具有较高的内部一致性。通过重测信度检验的可重复性令人满意。通过与康斯坦特评分以及SF36和HAQ的相关量表在预期方向上获得显著相关性，确定了问卷的有效性。通过分析术前分数与随访分数之间的差异来评估对变化的敏感性。将分数变化与患者对术后自身状况问题的回答进行比较。新问卷的标准化效应量与SF36和HAQ相比具有优势。新问卷在区分表示肩部状况明显改善的患者与其他所有患者方面效率最高。这份肩部问卷为肩部手术提供了一种结果衡量方法，它简短、实用、可靠、有效且对临床重要变化敏感。
