On page 1575 of Phua et al. (Reference Phua, Kee, Koh, Rifkin-Graboi, Daniels and Chen2017), the work by Magiati et al. (Reference Magiati, Goh, Lim, Gan, Leong and Allison2015) should have been cited after the brief description of the Q-CHAT administered at 18 months, as this study examined the factor structure of the Q-CHAT in the GUSTO neurocognitive domain sample.
In addition, the Q-CHAT language factor was inadvertently included in Table 6. This factor and findings related to this factor should not be considered or interpreted, as the Q-CHAT language factor has only four items and low internal consistency. Only the Q-CHAT total social and behavioral factors should be considered in the results and in the results’ interpretation.
The authors apologize for these errors.
