The preliminary analysis of the reliability and validity of the Chinese Edition of the CSBS DP.
The Chinese CSBS DP is a solid early screener for communication delays in 1-young learners.
01Research in Context
What this study did
Chu-Sui and team translated the Communication and Symbolic Behavior Scales Developmental Profile into Chinese.
They gave the forms to 171 parents of babies and toddlers in Taiwan.
Kids were 6-24 months old and came from clinics and the community.
What they found
The Chinese CSBS DP worked well.
Internal consistency was high and test-retest scores matched.
The tool correctly spotted kids with later delays, showing it can be trusted for early screening.
How this fits with other research
Narzisi et al. (2013) and Gabriels et al. (2001) already showed the CBCL 1½-5 and M-CHAT catch ASD risk in toddlers.
Lin et al. (2015) now adds the CSBS DP to that list, but for an even younger age band—6-24 months.
Limberg et al. (2017) and Vanvooren et al. (2017) proved Western screeners can travel; this study repeats the trick in Chinese, matching their positive findings.
Oryadi-Zanjani (2020) built a brand-new scale for Iranian infants, while Chu-Sui simply adapted an existing one—both paths end with reliable early tools.
Why it matters
If you serve Mandarin-speaking families, you can now use the Chinese CSBS DP with confidence at 12-month check-ups.

03Original abstract
This study marked a preliminary attempt to standardize the Chinese Edition of the Communication and Symbolic Behavior Scales Developmental Profile (Wetherby & Prizant, 2002; CSBS DP) to assist in the early identification of young children with special needs in Taiwan. The study was conducted among 171 infants and toddlers aged 1-2. It also included a follow-up study one year after the initial test. Three domestically developed standardized child development inventories were used to measure the concurrent validity and predictive validity. The Chinese Edition of the CSBS DP demonstrated overall good test-retest and inter-rater reliability. It also showed good concurrent and predictive validity. The current study yields preliminary evidence that the Chinese Edition of the CSBS DP could be a valuable assessment tool worthy of wider distribution. Future research should employ random sampling to establish a true national norm. Additionally, the follow-up study needs to include atypical groups and to expand to children aged 6-12 months to strengthen the applicability of the instrument in Taiwan.
