Ognitive Behavioural Therapy single case research proposal (4000words)

My assignment requires that I design a small scale CBT single case research proposal (4000 words) that could be implemented in clinical paractice (mental health) and provide information about the process of therapeutic change.
Part 1 of the proposal will take the form of a literature review detailing relevant psychological theory and discussing previous research in the area (2500 words). It is expected that this sction will show an understanding of a specific CBT model and provide a clear rational for the research proposal.
Part 2 (1500 words) will detail exactly how the proposal could be put into practice under headings below.
Research question/hypothesis: ie Exactly what question are you attempting to answer ? What do you hope to learn fronm the study?
Experimental design: ie Why is this an appropriate design for this research question compared to other methods?
Method: ie operationalise independant and dependant variables.
Participant: ie What kind of participant? inclusion and exclusion criteria
Measures: ie Ideographic and standardised
Clinical intervention: ie What would the intervention look like?
Data analysis: ie How would the data be presented or analysed (need to demonstrate through graphs etc which could be in appendix)
Ethical considerations: ie What ethical issues might be encountered? How could you justify the ethical considerations of this study? How could you safeguard against ethical problems?
Petential problems/obstacles: ie What potential problems might you encounter and how would you deal with them?

Note:
Part 1 of study must include a diagram of a specific CBT model with discussion theory underpinning it.
I have not developed a specific research question but have ideas of what it may entail. ie It would be useful if you could develop one around Obsessive Complusive Disorder (perhaps using a Salkovskis OCD model) . As explained above the model chosen would help guide the intervention. Maybe something related to OCD and problem (or compulsive ) gambling?
I would like the assignment text to be justified.

Finally,
The term method not Methodologyto be used and in assignment. Also, the assignment should begin by detailing the research methods (electronic, search engines, library etc
