They seem to show some effectiveness with adolescents, but is there any literature on really young children attempting or successfully implementing such strategies (in any form)?
Have you tried Google searching "self-management autism"? There are several articles in JABA in 2013 related to children with ASD and self-management. Also, here is the abstract for a meta-analysis about self-management: http://foa.sagepub.com/content/22/1/2.short
I haven't personally done any research on self-management, but I have used self-management programming and strategies with young children with ASD. I don't think that age is necessarily a key characteristic so much as skill level and ability to understand and appropriately identify the occurrence vs non-occurrence of a pre-determined behavior. I have used self-management strategies with children as young as age 6.
You're right, cognitive-functioning and skill level does make more sense in regard to the prerequisites necessary for implementation. I have read through several older articles pertaining to self-management and ASD, but have yet to look at the newer stuff JABA has. Thanks for the tips and insight, Amy and Kerry!
I guess preschool age would be fine. The problem is not maturity, but adaptation of the strategies for self-management. If you find out at what age they start developing coping strategies, you'll find the perfect age for starting.
