This study reports outcome in adolescents with autism who in their childhood received Early and Intensive Behavioral Intervention (EIBI). Nineteen children (16 boys) who had received two years of EIBI starting at a mean age of 2-years-and-11-months were followed up, on average, 12 years later. Results showed the participants significantly increased their cognitive and adaptive standard scores during the two years of EIBI, and that these gains were maintained at follow-up, 10 years after the EIBI had ended. Participants also showed a significant reduction in autism symptoms between intake and follow-up. At follow-up, none of the participants had received any additional psychiatric diagnoses, and none were taking any psychotropic medication. Results indicate that treatment gains achieved in EIBI are maintained into adolescence.

早期和强化行为干预 (EIBI) 的治疗收益可在 10 年后保持。

本研究报告了童年时期接受早期强化行为干预 (EIBI) 的自闭症青少年的结果。对平均年龄为 2 岁零 11 个月开始接受两年 EIBI 的 19 名儿童（16 名男孩）进行了随访，平均随访时间为 12 年。结果显示，参与者在 EIBI 的两年期间显着提高了他们的认知和适应性标准分数，并且这些收益在 EIBI 结束 10 年后的随访中得以保持。参与者还表现出在摄入和随访之间的自闭症症状显着减少。在随访中，没有参与者接受任何额外的精神病诊断，也没有人服用任何精神药物。结果表明，在 EIBI 中获得的治疗效果一直持续到青春期。
