汉化版周历活动规划简版评测卒中后执行功能的信效度研究

Reliability and validity of Chinese version of Weekly Calendar Planning Activity-Short for post-stroke to evaluate executive functions

目的评价汉化版周历活动规划简版(WCPA-10)评测卒中患者执行功能的信度和效度。方法采用便利抽样法于2020年8月至12月通过在北京大学第一医院门诊和病房张贴海报的形式招募50例卒中患者参与本研究。所有受试者接受汉化版WCPA-10和执行功能表现测试(EFPT)的评测,并通过抽签的方式从50例受试者中随机选取30例受试者间隔2周后完成汉化版WCPA-10的第2次评测,评测内容包括汉化版WCPA-10中的安排填入数、遗漏数、准确数、错误数、遵守规则数、策略使用数、总时间和计划时间,以及以EFPT中的服药测试作为效标。采用组内相关系数(ICC)计算重测复本信度和评估者间信度(ICC值>0.90示信度高,0.70~0.89示信度良好,<0.69示信度较差),采用再测法进行内容效度分析,采用Spearman相关分析进行效标效度分析[相关系数绝对值(|ρ|)≥0.70示高度相关,|ρ|0.40~<0.70示中度相关,|ρ|<0.40示低度相关]。结果使用汉化版WCPA-10评测卒中患者的执行功能具有良好的重测复本信度和评估者间信度,各项评测指标的ICC值分别为0.70~0.98和0.92~1.00。汉化版WCPA-10安排填入数、遗漏数、准确数、遵守规则数、总时间、计划时间等评分指标与EFPT服药测试之间呈中度至高度相关[|ρ|分别为0.71(P<0.01)、0.71(P<0.01)、0.73(P<0.01)、0.53(P<0.01)、0.73(P<0.01)、0.47(P<0.01)];错误数和策略使用数与EFPT服药测试之间无显著相关(均P>0.05)。结论汉化版WCPA-10评估卒中患者的执行功能具有良好的信效度。

Objective To evaluate the reliability and validity of Chinese version of weekly calendar activity planning-short(WCPA-10)in assessing the executive functions(EFs)of post-stroke survivors.Methods Fifty post-stroke survivors were recruited to participate in this study.The convenience sampling method was used to recruit 50 stroke patients to participate in this study by posting posters in outpatients and wards of the Peking University First Hospital from August to December 2020.All were assessed by Chinese version of WCPA-10 and executive function performance test(EFPT).Among them,30 participants were randomly selected to be assessed by WCPA-10 again 2 weeks after the first one.WCPA-10 scores included entered appointments,missing appointments,total accuracy,total errors,rules followed,number of strategies used,total time and planning time,with“Drug use”in EFPT as an indicator for criterion validity analysis.Intra-group correlation coefficient(ICC)was used to calculate test-retest reliability and inter-evaluator reliability(ICC value>0.90 indicates high reliability,0.70-0.89 indicates good reliability,and<0.69 indicates poor reliability).The content validity was analyzed by test-retest method and the criterion validity was analyzed by Spearman test(correlation coefficient absolute value[|ρ|]0.70 or higher indicates high correlation,|ρ|0.40-<0.70 indicates moderate correlation,|ρ|<0.40 indicates low correlation).Results The Chinese version of WCPA-10 was used to evaluate the executive function of post-stroke survivors with good test-retest reliability and inter-evaluator reliability,with ICC values of 0.70-0.98 and 0.92-1.00,respectively.Moderate to high correlation was found of Chinese version of WCPA-10 entered appointments,missing appointments,total accuracy,rules followed,total time and planning time,with“Drug use”in EFPT(0.71[P<0.01],0.71[P<0.01],0.73[P<0.01],0.53[P<0.01],0.73[P<0.01]and 0.47[P<0.01]).There was no significant correlation between the number of errors and the number of strategies used with“Drug use”in EFPT(all P>0.05).Conclusion Chinese version of WCPA-10 is a reliable and valid tool for evaluating executive function of post-stroke survivors.
