The Assessment Phase of the Intervention Research Framework: Study Design

Abstract

This chapter is the first of four chapters providing details about the Assessment phase of the Intervention Research Framework. This chapter provides information about the three distinct types of longitudinal behavioural assessment that contributes to proof of evidence: efficacy; effectiveness, and efficiency research. This chapter also considered the elements of research design that are required for a well-designed and rigorously conducted research study. These elements include: the composition of the study team; the components of a high quality study design with particular emphasis on: statement of hypotheses and objectives; the inclusion of a control group; the development of a study analysis plan; considerations around validity and reliability; various forms of bias which threaten the viability of a study; ethical considerations associated with intervention research particularly in schools; and costs associated with intervention research. This chapter also provides a summary of the costs associated with the SHAHRP study, and outlines the limitations (or potential areas of bias) in the SHAHRP study.

Objectives: By the end of this chapter readers will be able to:

• Describe the efficacy, effectiveness and efficiency research components of the Intervention Research Framework and the contribution that they make to evidence

• Identify the composition of an effective study team

• Identify the basic components of ‘good quality’ study design

• Identify potential sources of bias to a research study
