The writer I choose for this assignment will essentially be the same writer for the duration of this course. This course is building the first chapter of my dissertation, and as a result, it needs consistency. Please keep all previous assignments accessible; you will need them to complete the next assignment.
This assignment is the first chapter of my dissertation. So, each assignment in this course is built on the previous assignment. I will be building the literature review on this topic, which will be the final assignment for this course.
Degree: Criminal Justice 
Concentration: Homeland Security
Dissertation Topic.
***The relationship between mental illness and criminal behavior.***
To what extent does mental illness contribute to criminal behavior? How do various mental health disorders influence the types of crimes committed?
**moving forward, I will be focusing on quantitative study only**
Assignment: Begin this activity by reflecting on your revised problem and purpose statements. Select a method and design appropriate for a doctoral dissertation study.  Quantitative studies must demonstrate both internal and external validity (e.g., large, random samples, statistical power, and representativeness). Qualitative studies must demonstrate validity within the context of the specific qualitative design (e.g., credibility, dependability, transferability, trustworthiness). Replication studies are not permitted. Your summary must address all of the following items.
Access SAGE Research Methods for a refresher on research terminology.
Continue your work on the template provided in Week 2 of the course and construct a 1 page rationale for your research method and design selection. Be sure to include the following discussions:
Provide a brief summary of the methodology and the type of data that will be collected. Describe and substantiate the appropriateness of the method to respond to the stated problem and purpose.
Provide a brief summary of the research design that substantiates its appropriateness to respond to the stated problem and purpose and includes a description of the data collection procedure and type of analysis.
Note how the proposed method and design accomplish the study goals, why the design is the optimum choice for the proposed research.
Provide appropriate foundational research method support for the proposed study design; cite seminal scholarly sources.
Explain the particular data-gathering techniques and data analysis processes.  Sample size of the study population should be identified and must be appropriate and justified based on the nature of the study design. Quantitative analyses must include justified sample size determination. A brief overview of the study design, variables/constructs, instruments, and analyses is provided based on current literature describing why the proposed method and design were chosen to address the study’s research question(s).
Indicate why the selected research methodology and design are the best choices for the study by explaining how they align with the problem and purpose statements as well as the research questions.
