Title:The Development and Cross Cultural Examination of the Korean Brief Autism Diagnostics Interview (KBADI) and the ADI-R Algorithms in Korea.

Background:  As countries and cultures around the world become more aware and concerned about autism spectrum disorders, there is a need to develop measures that are grounded in those cultures. The Autism Diagnostic Interview (ADI-R) is an accepted standard method for providing a diagnosis of autism spectrum disorder. The ADI-R has been translated into over thirty languages around the world. At times, clinicians have found it challenging to administer the full ADI-R. This study aims to develop a brief Korean ADI-R that can give more insight into the role of culture and how it can be more grounded in Korean culture.

Objectives:  To development of the Korean Brief Autism Diagnostic Interview (KBADI) measure for use in the Korean culture. To predict the diagnosis of autism spectrum disorder in Korean children as accuracy with the KBADI as with the Korean-translated ADI-R algorithm for two groups of Korean children: children under the age of ten with fluent language and children ten years of age and older with fluent language.

Methods:  The total number of participants included 286 school-aged Korean children. This sample of children was part of a larger epidemiological study of autism in South Korea. The Korean-translated Autism Diagnostic Interview (ADI-R) was administered as part of a full diagnostic assessment.

Results:  A single-parameter item response (IRT) model (Rasch, 1960) was used to select items for the Korean Brief Autism Diagnostic Interview (KBADI) from the full Korean-translated ADI-R. The KBADI is a 23-item measure grounded in Korean culture to provide a diagnosis of autism spectrum disorder. The KBADI measure is consistent with the criteria of autism; items include deficits in social development, communication, and repetitive/stereotyped behaviors and interests. Correlation analyses revealed that the KBADI and Korean-translated ADI-R algorithms for both groups were strongly correlated. The ROC curve statistics indicated that the Korean Brief Autism Diagnostic Interview (KBADI) can predict the diagnosis of autism spectrum disorders with accuracy comparable to that of the Korean-translated Autism Diagnostic Interview-Revised (ADI-R) diagnostic algorithms for two age groups.

Conclusions:  This study was successful in creating the KBADI. The KBADI is only 23 items and uses one version from age 7 – 12 and is as accurate as the ADI-R algorithm with this sample. The development of this measure recognized the core characteristics of autism while also accommodating to cultural influences in South Korea.
