Psychometric properties of the Chinese version of the Psycho-educational Profile-Revised (CPEP-R).
The Chinese PEP-R is ready for your Cantonese- or Mandarin-speaking preschool clients.
01Research in Context
What this study did
The team translated the Psycho-educational Profile-Revised into Chinese. They then checked if the new CPEP-R gives steady scores across raters, days, and other tests.
All children already had an autism diagnosis and lived in Hong Kong.
What they found
The Chinese PEP-R showed strong reliability and validity. It lined up well with other trusted measures, so clinicians can feel safe using it.
How this fits with other research
Ho et al. (2013) did the same kind of psychometric work for the Gumpel Readiness Inventory in Hong Kong preschools. Both studies found the translated tools held up well, giving local BCBAs two solid choices.
Tiznobeik et al. (2025) repeated the process in Iran with the First Year Inventory. Again, the translated tool passed its checks, showing this cross-cultural pattern is not a one-off.
Courchesne et al. (2019) warned that regular IQ tests can fail with minimally verbal autistic preschoolers. Their caution makes a validated tool like the CPEP-R even more useful, because it profiles developmental skills instead of relying on language-heavy items.
Why it matters
If you assess Mandarin- or Cantonese-speaking preschoolers, you now have a proven tool. Use the CPEP-R to set baseline skills, track tiny gains, and show parents clear numbers. It saves you from guessing whether culture or language skewed the results.

03Original abstract
The purpose of this study was to examine the reliability and validity of the Chinese version of the Psycho-educational Profile-Revised (PEP-R). The Chinese PEP-R (CPEP-R) was administered to 63 preschool children with symptoms of autistic disorder recruited from special child-care centers in Hong Kong. Results showed that the scales of the CPEP-R were internally consistent, reliable across raters and temporally stable. Regarding the concurrent validity of the CPEP-R, the developmental score and developmental age assessed by the CPEP-R were significantly correlated with the Merrill-Palmer Scale of Mental Tests and the Hong Kong Based Adaptive Behavior Scale. The Behavioral Scale of the CPEP-R was also significantly related to the Childhood Autism Rating Scale. Besides replicating the findings in the Western context, the present study suggests that the psychometric properties of the PEP-R are stable across cultures and the related findings support the cross-cultural reliability of the tool.
