Abstract The aim of this paper was to examine the validity and reliability of age band 1 of the Movement Assessment Battery for Children-Second Edition (MABC-2) in preparation for its standardization in mainland China. Interrater and test-retest reliability of the MABC-2 was estimated using Intraclass Correlation Coefficient (ICC). Cronbach's alpha for each item and Item-total correlation were used to determine internal consistency. The content validity was determined by the Item-level content validity index (I-CVI). Confirmatory factor analysis was used to examine the factorial validity of the MABC-2 test. The correlation coefficients between the MABC-2 and the Peabody Developmental Motor Scales-2 (PDMS-2) were used to assess the criteria-related validity. The Cronbach's alpha values of all eight items together were moderate but acceptable. The correlation coefficients between each test item and the total score were moderate except for two items. The ICC of interrater and test-retest reliability for each test items was good. The I-CVI of each item was excellent (each above 0.78). The result of confirmatory factor analysis showed that the goodness-of-fit indices of the adjusted model were good (each above 0.9), indicating a satisfactory fit of the data to the model. The total score on MABC-2 and PDMS-2 was correlated well (r=0.631). It is concluded that the reliability and validity of age band 1 of MABC-2 were fair in this study based on a large sample. However, there was a need to adjust part of items to improve the test's psychometric properties when it is used in Chinese children. Copyright © 2012 Elsevier Ltd. All rights reserved.
