When drafting your purpose statement, you should consider using this model:

How + Who + What + Where

How: What type of study are the researchers suggesting?

For example: Qualitative Interpretative Phenomenological Analysis

Who: Who are you wanting to study? Is it a specific group, community, or demographic?

For example: Non-medical elementary school employees

What: What are you wanting to research about this particular person, group, or community? What is a burning question you want answered?

For example: Perceptions on caring for children with chronic medical conditions in the absence of a school nurse

Where: Where do these people or population live, attend school, or work?

For example: Public elementary schools in the southeastern United States

Once you have identified the how, who, what, and where, you should be able to draft your purpose statement similar to this statement:

The purpose of this qualitative interpretative phenomenological analysis is to examine the perceptions of non-medical school employees on caring for students in the absence of a school nurse at public elementary schools located in the southeastern United States.

Again, you should remember, this is only a starting point. Your purpose statement will likely change as you progress; however, this will get you started so that you can enter an in-depth review of literature.
