Mean and SD of SELSI Raw and AE Scores of ASD and DLD Groups

ASD, autism spectrum disorder; DLD, developmental language delay; AE, age equivalent; SD, standard deviation; SELSI, Sequenced Language Scale for Infants.

These were the results of raw receptive-expressive scores and their age equivalent scores in ASD and DLD groups by SELSI. Significant differences were identified in receptive scores and receptive AE scores in all three subgroups between ASD and DLD by Independent t-test. However, no considerable results were confirmed in expressive score and expressive AE scores. No significant differences in ASD and DLD group identified expressive scores and expressive AE scores.

^*Receptive score t=-2.665, p<0.011, receptive AE (month) t=-2.775, p<0.008.

^†Receptive score t=-4.475, p<0.001, receptive AE (month) t=-4.474, p<0.001.

^‡Receptive score t=-3.386, p<0.002, receptive AE (month) t=-3.393, p<0.002.
