Patient-related outcome measures (PROMs) are commonly used to gauge treatment effects in patients with anterior cruciate ligament (ACL) deficiency. Valid measures of specific conditions depend on relevant item content. While item content can be derived either from clinicians (face validity) or from patients, item relevance and comprehensiveness can only be confirmed by the patient (content validity). Focus group and single interviews were conducted with patients' pre- and post-ACL reconstruction in order to construct a condition-specific PROM for the target patients. One hundred fifty-seven items from a previously conducted literature search were used as a basis for content genesis. Content saturation was achieved after three focus groups and seven single interviews. Thirty-eight items from the literature search were directly endorsed, and five modified items were endorsed. Twelve new item themes with verbatim content emerged. Thus, a 55-item pilot PROM consisting of six conceptual domains was assembled. We have constructed a condition-specific PROM for measurement of surgical and non-surgical treatment effects on ACL deficiency. The instrument possesses face and content validity. A pilot survey to assess the psychometric properties will be performed using Rasch measurement theory.
患者相关结局测量（PROMs）常用于评估前交叉韧带（ACL）缺陷患者的治疗效果。特定条件的有效测量取决于相关项目内容。虽然项目内容可以从临床医生（表面效度）或患者中得出，但项目相关性和全面性只能由患者（内容效度）确认。对 ACL 重建前后的患者进行了焦点小组和单项访谈，以构建针对目标患者的特定于疾病的 PROM。从先前进行的文献检索中使用了 157 个项目作为内容生成的基础。经过三个焦点小组和七次单项访谈，实现了内容饱和度。文献检索中有 38 个项目直接得到认可，有 5 个修改后的项目得到认可。出现了 12 个具有逐字内容的新主题项目。因此，组装了一个包含六个概念领域的 55 个项目的初步 PROM。我们已经构建了一种特定于疾病的 PROM，用于测量 ACL 缺陷的手术和非手术治疗效果。该工具具有表面效度和内容效度。将使用 Rasch 测量理论进行初步调查以评估心理测量特性。
