The deficiencies model of an introduction is a general template for writing a good introduction.
It is a popular approach used in the social sciences, and once its structure is elucidated, the
reader will find it appearing repeatedly in many published research studies. It consists of five
parts, and a separate paragraph can be devoted to each part, for an introduction of about two
pages in length:
1. The research problem
2. Studies that have addressed the problem
3. Deficiencies in the studies
4. The significance of the study for particular audiences
5. The purpose statement
