By Day 7, using the 4 articles you have located so far to answer your PICO question as a guide, you are to design your own study ("Future Research" - this is part of your Comprehensive Paper) that could help to answer your PICO question. Your study must be different in some fashion from the other studies you have read to address a "gap" in this literature. For example, you may choose to investigate a different population, use a different length of time for the intervention, or use a different instrument. Your paper must include the following headings (in APA!): Participants (& why you are choosing this pool of participants) Instrument (& why you are choosing this instrument) Procedures (the participants' process) Statistics (What statistical analysis would you choose to analyze data) Different (How this study is different from all 4+ studies you have analyzed for your PICO question thus far) Your paper is to be a maximum of 3 pages in length, must follow APA formatting.
