Diagnostic values of questionnaires of Convergence Insufficiency Symptom Survey and College of Optometrists Vision Development Quality of Life in the screening of convergence insufficiency

AIM:To compare and analyse the diagnostic efficacy of the College of Optometrists Vision Development Quality of Life Questionnaire(COVD-QOL)and the Convergence Insufficiency Symptom Survey(CISS)in detecting convergence insufficiency and to compare their diagnostic value in clinical applications.METHODS:Using the diagnostic test method,62 adult patients with convergence insufficiency(age:24.74±3.75y)and 62 normal participants(age:23.61±3.13y)who visited the Optometry Clinic of West China Hospital of Sichuan University from April 2021 to January 2023 were included.All subjects completed the CISS and COVD-QOL.Statistical analysis of the sensitivity and specificity of the CISS and COVD-QOL and comparison and joint experimental analysis of their diagnostic efficacy were performed.RESULTS:The sensitivity of the CISS and COVD-QOL for convergence insufficiency was 64.5%and 71.0%,respectively,while the specificity was 96.8%and 67.7%,respectively.Compared to the CISS alone,the combination of the CISS and COVD-QOL demonstrated lower sensitivity and specificity.The areas under the receiver operating characteristic curve of CISS,COVD-QOL and CISS combined with COVD-QOL were 0.806,0.694 and 0.782,respectively.CONCLUSION:Considering the low sensitivity of the CISS and the low specificity of the COVD-QOL,it is recommended to supplement these questionnaires with other screening tests for the detection of convergence insufficiency.

On Developing the Questionnaire for Evaluating PBL's Multiple Learning Achievements

How to comprehensively,scientifically,objectively and impartially evaluate the multiple learning achievements of the PBL model should be highlighted when PBL is introduced and applied.A questionnaire of a total of 23 items involving such dimensions of language proficiency,subject contents and 21 st Century skills was designed.Its reliability and validity were tested and well-met with the statistical requirements.

肿瘤多学科协作诊疗有效实践认知调查问卷的研制和信效度检验

目的 编制肿瘤多学科协作诊疗(multidisciplinary diagnosis and treatment,MDT)有效实践的认知调查问卷,并验证其信度和效度。方法 基于文献分析和深度访谈,从“结构-过程的特征”“结果(成效)”版块两个版块构建问卷的主题框架,通过专家咨询进行问卷修订和完善。采用方便抽样对医务人员开展问卷调查,采用项目分析、探索性因子分析和验证性因子分析进行条目筛选和信效度检验。结果 最终确定的问卷中,“结构-过程的特征”版块划分为4个子表、10个维度、47个条目,“结果(成效)”版块包括3个维度、15个条目。两个版块的Cronbach’s α系数分别为0.986、0.966,分半系数分别为0.950、0.942。探索性因子分析中,“结构-过程的特征”版块4个子表依次提取2、4、2、2个公因子,累计方差贡献率在77.896%~82.431%之间,“结果(成效)”版块提取3个公因子,累计方差贡献率为80.778%。验证性因子分析显示,两个版块修正后的因子模型大部分拟合指标符合临界值标准,各维度的平均方差抽取量AVE值均大于0.50、CR值均大于0.70。“结构-过程的特征”版块中条目得分与各子表总分的相关系数,以及“结果(成效)”版块中条目得分与总分的相关系数均大于0.65(P <0.05)。结论 本研究的问卷编制过程合理,且具有较好的信度和效度,可用于调查我国医务人员对肿瘤MDT有效实践的认知情况。
