Relationship between the Developmental Coordination Disorder Questionnaire 2007 and the Bruininks-Oseretsky Test of Motor Proficiency Second Edition in Korean Children

Abstract

This study investigated the relationship between the Developmental Coordination Disorder Questionnaire 2007 (DCDQ’07) and the Bruininks-Oseretsky Test of Motor Proficiency Second Edition (BOT-2) in Korea. This study also adjusted the cutoff score of the DCDQ’07 based on the BOT-2 for Korean children. A total of 256 children were recruited from communities in Korea. They were divided into two age groups: 8 to 9 years old and 10 to 12 years old. Children performed the BOT-2, and their parents completed the DCDQ’07. The correlation between the DCDQ’07 and the BOT-2 was analyzed. The adjusted DCDQ’07 cutoff score for Korean children was calculated using the BOT-2 as the criterion through a receiver operating characteristic curve. A significant correlation between the DCDQ’07 and the BOT-2 was found, indicating that Korean parents’ perception of children’s motor skills was related to their children’s actual motor proficiency. The adjusted cutoff score of the DCDQ’07 had a sensitivity of 72.7–85.7% and a specificity of 62.5–64.0%. This study demonstrated that children’s motor skills reported by Korean parents on the DCDQ’07 were valid based on a community sample. The adjusted cutoff score of the DCDQ’07 could be used to identify children suspected of having a developmental coordination disorder.

Validity of the BOT-2 Short Form for Korean School-Age Children: A Preliminary Study

“…Data were collected between November 2018 and June 2022. The BOT-2 was administered using a procedure similar to that described by Yoon et al [ 17 ].…”

“…The participants were divided into three age groups: 7 years, 8–9 years, and 10–12 years [ 17 , 21 , 32 ]. The SF data were derived from the CF data.…”

“…To examine the usefulness of the SF as a screening tool, the sensitivity and specificity of the SF using the CF as a reference were calculated. Children in below average or lower categories of the CF total motor composite were assumed to have probable DCD [ 17 , 38 ]. Sensitivity was considered as the proportion of children in the below average or lower categories of the SF among children who were also in the below average or lower categories of the CF.…”

“…There are two forms of the BOT-2: the complete form (CF) and the short form (SF). The CF provides comprehensive information on motor function, and is recognized as the gold standard for evaluating motor performance at developmental stages [ 16 , 17 ]. Of the 53 items comprising the CF, 14 items were selected to constitute the SF.…”
