Efficacy analysis of early start Denver model in children with autism spectrum disorder / 中华行为医学与脑科学杂志

ABSTRACT

Objective To investigate the effect of Early Intervention Denver Model ( Early Start Denver Model,ESDM) on children with autism spectrum disorder( ASD). Methods From May 2017 to April 2018,forty four children aged 2-5 years with ASD were enrolled in the study and were randomly divided into the experimental group(n=20) and the control group (n=20). The experimental group received ESDM rehabilitation intervention and the control group received conventional rehabilitation intervention. Before and 6 months after intervention,all children were assessed by the Psycho-educational Profile-3rd Edition ( PEP-3). Results After 6 months of intervention,the developmental age of cognition (30 (26,34),33(30,44);Z=-3. 728,P<0. 001),imitation (33(29,40),38( 32,43); Z=-2. 010,P=0. 044),expression language (29(23,39),41( 33,50); Z=-3. 923, P<0. 01), receptive language ( 25 ( 20,32),34 ( 28,38); Z=-3. 727,P<0. 01) and fine motor (29(23,41),39(33,47) ;Z=-2. 704,P=0. 007) of the control group were significantly higher than those before intervention. In the experimental group,the developmental age of cognition (25 ( 21,32),37 ( 32,40); Z=-3. 922, P<0. 01),imitation ( 22 ( 17,35),39 ( 38,42); Z= -3. 826,P<0. 01),expression language (30(24,35),47( 37,53); Z=-3. 824,P<0. 01),receptive lan-guage (22(15,32),37(30,43); Z=-3. 924,P<0. 01),fine motor (25(22,33),43(30,52); Z=-3. 924, P<0. 01) and gross motor ( 24(17,38),40(27,43); Z=-3. 523,P<0. 01) were significantly higher than those before intervention. Compared with the control group,the experimental group had significantly greater changes in the five regionscognition(6(3,10),11(10,20); Z=-2. 821,P=0. 005),expression language (6(4,9),12(7,18); Z=-3. 278,P=0. 001),receptive language(5(3,10),12(7,18); Z=-3. 299,P=0. 001),fine motor (7(1,10),13(10,22); Z=-3. 038,P=0. 002)and gross motor(1(0,10),11(5,16);Z=-2. 568,P=0. 01) of PEP-3 after intervention. Conclusion Both conventional intervention and ESDM intervention can improve the cognitive,expression language,receptive language,imitation and fine motor abili-ty of children with ASD aged from 2 to 5 years,but ESDM intervention is more effective on improving the cog-nitive,language,imitation and fine motor ability of children with ASD.
