儿童青少年体力活动量表信效度评价
|
摘要
目的评价我国儿童青少年专用体力活动量表的信效度,为在儿童及青少年人群中开展体力活动流行病学调查提供可靠的测量和评价工具。方法通过分层整群抽样,于2013年和2016年抽取南京市小学四年级至高中三年级的学生作为研究对象,采用体力活动日记和加速度计对量表进行信效度验证。依据中高强度体力活动时间,使用Cronbachα系数评价量表信度,采用Spearman相关系数和Bland-Altman图评价量表效度。结果使用体力活动日记进行验证的有效人数为815人,量表所测量的中高强度体力活动的Cronbachα系数为0. 73,量表与体力活动日记测量值的相关系数为0. 59。Bland-Altman一致性分析显示量表与体力活动日记对中高强度体力活动测量结果的一致性为95. 8%。使用加速度计进行验证的有效人数为624人,Cronbachα系数分别为0. 72,量表与加速度计测量值的相关系数为0. 36。Bland-Altman分析显示量表与体力活动日记对中高强度体力活动测量结果的一致性为95. 5%。结论该儿童青少年体力活动量表信效度良好,可用于人群水平的儿童青少年人群体力活动相关的流行病学研究。
Objective To evaluate the validity and reliability of an item-specific physical activity scale for Chinese children and adolescents( I-PASCA). Methods Students from Grade 4-12 in Nanjing were randomly selected using a multi-stage sampling approach,7-days physical activity( PA) level was recorded by self-reported I-PASCA and PA log and were objectively measured with accelerometers. The total moderate and vigorous PA( MVPA) time was calculated. Cronbach α was calculated to estimate the reliability of I-PASCA. Pearson correlation coefficient and Bland-Altman were used to examine I-PASCA's validity. Results There were 815 students recruited in 2013 to evaluate the reliability and validity of IPASCA using PA log. Cronbach α for I-PASCA was 0. 73 regarding moderate and vigorous PA( MVPA).The Spearman correlation coefficients of the values of PA recorded by I-PASCA and PA log were 0. 59 for MVPA,and the Bland-Altman coefficient was 95. 8% for MVPA. 624 students were involved to examine the reliability and validity of I-PASCA using accelerometers. Cronbach α for I-PASCA was 0. 72 regarding MVPA. The Spearman correlation coefficient was 0. 36 for MVPA,while the Bland-Altman coefficient was95. 5% for MVPA. Conclusions The I-PASCA,the first physical activity questionnaire specific to Chinese children and adolescents,shows acceptable reliability and validity and can be used to evaluate Chinese students' physical activity level in population-based studies.
