aba research, time frame for services

[Guest guest]

Hi group

I have posted variations of this question before, but I would

appreciate any and all responses. I am having to respond

Does anyone know of a study which specifically focused upon and/or

asserted there is a time frame in which intensive aba is effective and

after that loses it's effectiveness.

The studies I have read (I am not an expert) suggest that aba is most

effective in raising IQ's in the first year and in subsequent years has

the most benefit for socal and behavioral remediation. The later key

for successful integration in typical classrooms (with or without a

shadow/aide). Therefore, the benefit of aba may remediate different

areas of deficiets at different intervals, but the overall benefit is

ongoing and continues to support overall lesening of autistic

characteristics. The time period in which the aba was conducted seems

to vary in studies between 2-4 years in general. In the studies I have

not found any discussion of research based limitation of intensive

services (home-based or clinical).

I have not found a study which places a time constraint-namely 3 years-

on the effectivenss of aba.

I would appreciate all comments and edification on this topic.
