The Grille d'évaluation de la sécurité à la marche (GEM scale) is a performance-based tool developed to fill the need for an objective assessment of walking safety for older adults. It underwent a three-phase process of content validation.
A mailed questionnaire was used to assess the representativeness of the walking items (5-point pertinence scale). Subsequently, two physiotherapist focus groups (n = 20) were held to further evaluate the relevance of the scale and the walking items. Finally, a pilot study was completed with 3 raters administering the GEM scale to 12 hospitalized patients.
Comments and descriptive statistics (percentages) were analyzed from the questionnaire results and focus groups. On completion of the pilot study, which assessed 12 patients on the GEM scale, additional analyses were performed to address the theoretical background, the administration manual, the walking items, the scoring scale, and interpretation of the scale. Following each step, modifications were made to reflect the results of the analyses.
The three-phase content-validation process demonstrated the relevance of this instrument and its representativeness as a walking safety assessment tool for older adults.
步行安全评估量表（GEM量表）是一种基于表现的工具，旨在满足对老年人步行安全进行客观评估的需求。它经历了一个由三个阶段组成的内容效度验证过程。
采用邮寄问卷来评估步行项目的代表性（5分相关性量表）。随后，举办了两个物理治疗师焦点小组（n = 20），以进一步评估该量表及步行项目的相关性。最后，完成了一项预试验研究，由3名评估者对12名住院患者使用GEM量表。
对问卷结果和焦点小组的评论及描述性统计数据（百分比）进行了分析。在完成对12名患者进行GEM量表评估的预试验研究后，进行了额外分析，以探讨理论背景、使用手册、步行项目、评分量表以及量表的解读。在每个步骤之后，都进行了修改以反映分析结果。
三个阶段的内容效度验证过程证明了该工具的相关性及其作为老年人步行安全评估工具的代表性。
