Background
Early diagnosis of autism spectrum disorders allows to start a therapy tailored to the child - the earlier it happens, the better the results. This study marked a preliminary attempt to prepare culturally and linguistically adapted Polish version of the Communication and Symbolic Behavior Scales-Developmental Profile – Infant-Toddler Checklist (CSBS-DP ITC).
Method
The study was conducted among 1471 Polish parents of children from the general population aged 6 to 24 months, 490 of them participated in the follow-up. An additional 122 pairs of parents completed the questionnaire to determine reliability using the inter-rater method. The collected data were statistically processed to calculate the reliability and validity of the Polish version of the CSBS-DP ITC questionnaire.
Results
The results indicated a very good fit of the one-factor and three-factor models in confirmatory factor analysis. Both one-factor and three-factor model showed satisfactory fit in both sex subsamples. The total score of CSBS-DP ITC demonstrated satisfactory internal consistency, Cronbach's α = .92 and McDonald’s ω = .92. In test-retest all the correlation coefficients between the first and second measurements were above.70, proving a satisfactory level of stability.
Conclusions
The Polish version of the CSBS-DP-ITC is a reliable tool for the early screening of autism spectrum disorder, but further studies on sensitivity and specificity are essential.
