研究设计。我们构建了一个结果问卷来评估患者的满意度和表现，并区分青少年特发性脊柱侧弯患者。目的：确定一种新的测量脊柱侧凸患者进展的生活质量测量工具的可靠性和有效性。对青少年特发性脊柱侧凸手术治疗的荟萃分析表明，尚不存在对结果的统一评估。此外，患者的幸福感测量与过程测量(例如，X光片)的报告并不一致。这确立了标准化问卷的必要性，以结合过程测量来评估患者的测量。该工具由24个问题组成，通过因子分析将其分为七个等权重的领域：疼痛、一般自我形象、术后自我形象、一般功能、总体活动水平、术后功能和满意度。调查问卷大约需要5分钟才能完成，并以预定的时间间隔进行。来自3个不同地点的244名患者对问卷进行了回复。基于内部一致性的信度得到确认，每个领域的Cronbach‘sα系数均大于0.6。此外，通过对正常对照的重测，各领域的相关系数均大于0.68。同样，为了确定问卷的有效性，将普通高中生的回答与患者的回答进行了比较。两组在P<；0.003的领域有一致的差异。最大的差异是疼痛(对照组，29.96+/-0.20；患者，13.23+/-5.55)和一般活动水平(对照组，14.96+/-0.20；患者，12.16+/-3.23)。研究领域与患者满意度之间的关系显示，疼痛与满意度的相关性最大(皮尔逊相关系数r=-0.511；P<；0.001)，其次是自我形象(r=0.412；P<；0.001)。本调查问卷介绍了青少年特发性脊柱侧凸手术患者通过检查几个领域来评估结果的方法。它还允许在脊柱侧弯患者成年后对他们进行动态监测。这是一种经过验证的仪器，具有极高的可靠性。
Study Design. An outcome questionnaire was constructed to evaluate patient satisfaction and performance and to discriminate among patients with adolescent idiopathic scoliosis.Objectives. To determine reliability and validity in a new quality-of-life instrument for measuring progress among scoliosis patients.Summary of Background Data. Meta-analysis of the surgical treatment of adolescent idiopathic scoliosis determined that a uniform assessment of outcome did not exist. In addition, patient measures of well-being as opposed to process measures (e.g., radiographs) were not consistently reported. This established the need for a standardized questionnaire to assess patient measures in conjunction with process measures.Methods. The instrument consists of 24 questions divided into seven equally weighted domains as determined by factor analysis: pain, general self-image, post operative self-image, general function, overall level of activity, postoperative function, and satisfaction. The questionnaire takes approximately 5 minutes to complete and is taken at predetermined time intervals. A total of 244 of patients from three different sites responded to the questionnaire.Results. The reliability based on internal consistency was confirmed with a Cronbach's alpha coefficient greater than 0.6 for each domain. In addition, acceptable correlation coefficient values greater than 0.68 were obtained for each domain by the test-retest method on normal controls. Similarly, to establish validity of the questionnaire, responses of normal high school students were compared with that of the patients. Consistent differences were noted in the domains between the two groups with P < 0.003. The largest differences were in pain (control, 29.96 +/- 0.20; patient, 13.23 +/- 5.55) and general level of activity (control, 14.96 +/- 0.20; patient, 12.16 +/- 3.23). Examination of the relationship between the domains and patient satisfaction showed that pain correlates with satisfaction to the greatest degree (Pearson's correlation co-efficient, r = -0.511; P < 0.001), followed by self-image(r = 0.412; P < 0.001).Conclusions. This questionnaire addresses patient measures for evaluation of outcome in adolescent idiopathic scoliosis surgery by examining several domains. It also allows for dynamic monitoring of scoliosis patients as they become adults. This is a validated instrument with goad reliability measures.
