Visual impairment has distinct impacts on the activities of older adults. Quantifying the functional impact of visual loss would facilitate targeted rehabilitation. The objectives of this study were to: (1) develop an observational assessment of the functional visual performance of older adults using the Performance Quality Rating Scale (PQRS); (2) test the feasibility and inter-rater agreement in a pilot sample of older adults with visual impairment. A convenience sample of older adults with vision loss ( = 20) performed seven pre-selected activities. Performance was videoed ( = 126 videos) and rated by two raters using specific operational definitions. All participants completed the seven activities with the given resources and 90% of videos were successfully rated using the developed PQRS. Inter-rater agreement was substantial (weighted Kappa = 0.71; 95% confidence interval [CI] = [0.64, 0.79]) for all activities. The developed PQRS for functional vision is feasible, with substantial inter-rater agreement, to assess functional vision of older adults in an outpatient setting.
视力障碍对老年人的活动有明显影响。量化视力丧失的功能影响将有助于有针对性的康复。本研究的目的是：（1）使用表现质量评定量表（PQRS）开发一种针对老年人功能性视觉表现的观察评估方法；（2）在视力障碍的老年人的试点样本中测试其可行性和评分者间一致性。视力丧失的老年人便利样本（n=20）完成了七个预先选择的活动。表现被录像（n=126 个视频），并由两名评分者使用特定的操作定义进行评分。所有参与者都使用给定的资源完成了七个活动，并且 90%的视频都成功地使用开发的 PQRS 进行了评分。对于所有活动，评分者间的一致性很高（加权 Kappa=0.71；95%置信区间[CI]为[0.64，0.79]）。用于评估老年人功能性视力的功能性视力 PQRS 是可行的，具有很高的评分者间一致性，可在门诊环境中评估老年人的功能性视力。
