Document Summary

For internal validity, we want know if groups are comparable. Makes it different to compare both groups of children. Bad for external validity: no longer sure that the sample will generalize. Criteria for a treatment to be identified as effective: A large series (>=9) of single-case study designs demonstrating efficacy or. At least 2 between group design experiments (rcts) Emphasizes that human development occurs in a set of systems; when thinking about treating disruptive behaviours we can intervene at more than one of these levels. Think about not just intervening on the person but also on some of those systems. Problem-solving skills training: intervention at the level of the individual (the child) Multisystemic therapy: incorporates elements of problem solving skills training and parent management training but also thinks about the broader systems e. g. school, neighborhood. Work with the child to reduce behaviour problems. The underlying theory is the social-information processing model.
