为了开发识别青光眼患者知识缺陷和学习障碍的指标，本研究旨在验证青光眼知识评估，以用于评估青光眼患者的知识。当患者表现出对疾病及其治疗的更多了解时，青光眼治疗依从性似乎有所改善。本研究旨在验证青光眼患者人群中的青光眼知识评估，以帮助患者教育评估和干预。国家眼健康教育计划（NEHEP）的青光眼知识评估以前被认为是评估青光眼患者知识的有用措施。该问卷在青光眼患者中进行沿着更全面的49个问题的检查。对人口统计数据和卫生知识普及情况进行了评估。进行统计分析以评估评估的有效性。共有12名青光眼患者完成了知识评估。患者的平均±标准差年龄为69±14岁，青光眼的持续时间为14±13年。参与者在NEHEP评估中的平均得分为7.3±0.8（10分，73%正确），而在综合评估中的平均得分为29.3±7.3（49分，60%正确）。NEHEP的α系数为0.592，累积评估的α系数为0.872。个别问题的P值（考生正确回答的比例）范围为0至1。每个问题的项目点-二分相关值范围为-0.402至0.813。NEHEP测验可能是一个很好的起点，为发展一个可靠的知识评估工具，以衡量和监测青光眼知识，由于其简洁的性质和合理的难度水平。这项研究表明，目前可用的问卷中包含的问题在难度和区分知识水平的能力方面差异很大，这可能最终会影响现有考试的可靠性和实用性。进一步研究目前评估中的个别问题和教学要点，可能有助于在未来构建越来越可靠和有用的知识评估。
To develop metrics to identify knowledge deficits and barriers to learning in glaucoma patients, this study seeks to validate a glaucoma knowledge assessment to use in the evaluation of knowledge in glaucoma patients. Glaucoma treatment adherence appears to improve when patients demonstrate a greater knowledge of the disease and its treatment. This study seeks to validate a glaucoma knowledge assessment in a glaucoma patient population to assist in patient educational assessments and interventions. The National Eye Health Education Program’s (NEHEP) glaucoma knowledge assessment has previously been suggested as a useful measure to assess glaucoma patient’s knowledge. This questionnaire was administered in glaucoma patients along with a more comprehensive 49-question examination. Demographic data and health literacy were assessed. Statistical analyses were performed to assess the validity of the assessments. A total of 12 glaucoma patients completed the knowledge assessments. The mean ± standard deviation age of the patients was 69±14 years, and the duration of glaucoma was 14±13 years. The participants’ mean score on the NEHEP assessment was 7.3±0.8 (of 10, 73% correct) vs 29.3±7.3 (of 49, 60% correct) on the comprehensive assessment. The value of coefficient α was 0.592 for NEHEP and 0.872 for the cumulative assessment. The P-value (proportion of examinees answering correctly) ranged from 0 to 1 for individual questions. Item point–biserial correlation values for each question ranged from −0.402 to 0.813. The NEHEP quiz may be a good starting point for the development of a reliable knowledge assessment tool to measure and monitor glaucoma knowledge, due to its concise nature and reasonable level of difficulty. This study suggests that questions included in the currently available questionnaires vary widely in difficulty and ability to differentiate knowledge level, which may ultimately compromise reliability and utility of existing examinations. Further examination of individual questions and teaching points included in the current assessments may help to construct increasingly reliable and useful knowledge assessments in the future.
