Evidence-Based Practice

We are interested in researching evidence-based interventions for individuals with autism spectrum disorders. Our work in this area has focused on quantitative synthesis (meta-analysis) of treatment outcome research.

 

Campbell reviewed the efficacy of behavioral interventions for reducing self-injurious, aggressive, and other problem behaviors exhibited by individuals with autism spectrum disorders.

Efficacy of Behavioral Interventions. A Quantitative Synthesis of Single-Subject Research 2003 RIDD

Drs. Herzinger-Delfs and Campbell examined the impact of various forms of functional assessment in behavioral treatment planning for individuals with autism spectrum disorders.

Campbell conducted a meta-analysis of early intensive behavioral intervention (EIBI) outcomes from group-based studies which he presented at the International Meeting for Autism Research (IMFAR) in 2007. The poster appears below.

Preliminary Quantitative Synthesis of EIBI – IMFAR 2007

Campbell, Segall, and Dommestrup published a book chapter reviewing evidence-based practices for individuals with autism spectrum disorders and developmental disabilities. The chapter is accessible below.

 

 

Campbell delivered a presentation on evidence-based interventions for individuals with ASD at the UT-Memphis Boling Center for Developmental Disabilities’ Interdisciplinary Leadership Training series in December 2009.

Dr. Campbell’s presentation is accessible here:

Our interest in summarizing intervention results for single-subject designs has led to an interest in how best to synthesize findings from such designs. We have published work in this area.

Campbell examined the statistical relationship between several single-subject effect sizes.

Statistical Comparison of Four Effect Sizes for Single-Subject Designs 2004

Campbell and Herzinger-Delfs wrote a book chapter focused on statistical analysis of single-subject data in Dr. Gast’s recently published text on Single Subject Research Methodology in Behavioral Sciences.
