Research Methodology in Clinical Child and Adolescent Psychology

To continue to move the field of clinical child and adolescent psychology forward, researchers must systematically rely on research strategies that achieve favorable balances between scientific rigor and clinical relevance. This chapter presents an overview of modern methods and considerations that maximize both rigor and relevance in the evaluation of child and adolescent treatments. This research methodology chapter is organized around the four stages of a clinical trial: (a) planning a clinical trial; (b) conducting a clinical trial; (c) analyzing trial outcomes, and (d) reporting results. Sample selection, random assignment, control condition selection, treatment integrity, missing data, clinical significance, treatment mechanisms, and consolidated standards for communicating study findings to the scientific community are addressed. Collectively, the methods and design considerations detail modern research strategies for the continually evolving science of clinical child and adolescent psychology.
