Explanation:

A systematic review of literature applies a systematic methodology to place and critically analyze the information needed to work on a  research problem. This kind of research is essential for evidence-based health care.

Since the object under study has already been established (literature about interventions to treat PTSD), the first step would be to perform thorough research of several databases to find literature about it.
