Abstract
This discussion explores the systematic identification of inclusion and exclusion criteria for the PICO question: In adult patients diagnosed with Schizotypal Personality Disorder (STPD) treated as outpatients in psychiatric units, does Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT) affect symptoms of social anxiety? The literature search used a broad search of five major U.S.-based databases in a strict filter that only searched Level 1 and 2 evidence published in the last five years. Boolean terms and keyword phrases were used to limit the search. The selection was reduced to study samples of adult outpatients, comparisons of CBT and DBT, and quantifiable outcomes of social anxiety, to be most relevant and clinically feasible.

Database Search and Evidence Gathering Process:
To find high-quality and evidence-based research that would support the PICO question, I made a systematic search of several respected databases, including PubMed, CINAHL, PsycINFO, Cochrane Library, and Medline. I have deliberately chosen these databases, as they have the reputation of including peer-reviewed and scholarly information concerning psychiatric nursing and psychological therapies (Goossen et al., 2020). Combinations of words and MeSH terms that I employed were: distinctions between CBT/DBT and schizotypal personality disorder, as well as social anxiety. The refinement of search results was possible with the help of Boolean operators, such as the word AND and OR, and the search finally found results that compared the two therapy modalities and focused on the specific symptom of social anxiety in STPD adults (Jha et al., 2022).
The limits and filters played a paramount role in the refinement of the search to include only Level 1 and Level 2 evidence and those conducted in the US. The reason why such restrictions were implemented was to make sure that the research is not obsolete and relevant to outpatient psychiatric practice in the United States. I chose to retrieve research published not earlier than five years, with only English-language articles being included, and studies on human adults only being accepted. Also, only peer-reviewed and empirical research studies were incorporated to fulfill the requirements of high-levels of evidence (Vatkar et al., 2025). Relevance to the adult outpatient population, direct comparison between CBT and DBT and the evaluation of the results in terms of social anxiety symptoms became the major inclusion criteria. Articles with inpatient populations, adolescents or children, non-peer-reviewed articles, non-U.S. who wrote the article, and failure to directly compare CBT and DBT were all an exclusion criterion.
Through the five databases, I found out about 273 total articles. I also narrowed down these findings to abstract reading and using other criteria, like the study design (RCTs, systematic reviews, and meta-analyses) so that the studies would provide Level 1 or 2 evidence. Those articles containing mixed personality disorders without emphasis on STPD or those articles that contained either CBT or DBT but neither were an exclusion criteria. I focused on randomized controlled trials and meta-analysis of the relevance of CBT and DBT approaches to treating social anxiety symptoms in this specific population such as Bhattacharya et al. (2022) and Sadat et al. (2025).

How to create a PRISMA flow diagram
Dear Students,
To assist you in creating your literature diagram, please utilize the following resource: PRISMA Flow Diagram GuideLinks to an external site. . This guide provides step-by-step instructions and templates to help you accurately structure and document your literature review process.
A PRISMA diagram visually maps the flow of information through the different phases of a systematic or literature review. To ensure credibility and academic integrity, your diagram must reflect real numbers based on your database searches, screening, and selection, not estimates or placeholders.
Quick Guide: Creating a PRISMA Diagram with Actual Numbers
A PRISMA diagram maps how studies are identified, screened, and selected for your literature review. Use real, not estimated numbers. Follow these key steps:
1. Search and Record
· Use multiple databases (e.g., PubMed, CINAHL, PsycINFO).
· Document: search date, keywords, Boolean operators, filters.
· Total records retrieved (e.g., PubMed: 320, CINAHL: 290).
2. Remove Duplicates
· Use citation managers (e.g., Zotero, EndNote) to de-duplicate.
· Record how many were removed.
3. Screening (Title/Abstract)
· Note how many records were screened and excluded at this level.
4. Full-Text Review
· Report how many full-text articles were assessed.
· Exclude with reasons (e.g., wrong population, not peer-reviewed).
5. Final Inclusion
· Report number of studies included in:
· Qualitative synthesis
· Quantitative synthesis (if applicable)
Tips
· Avoid placeholders—use exact numbers.
· Keep detailed records in case you’re asked to verify.
· All the PRISMA components and the official PRISMA templateLinks to an external site. must be used to receive the full points in the main issues category for this assignment.
Let me know if you'd like a template filled out or help listing exclusion reasons.
Creating a Search Strategy
After studying Module 4: Lecture Materials & Resources , discuss the following:
·
1. Create and upload a literature flow diagram using the PRISMA templateLinks to an external site.
2. Describe the process used to narrow down the search results to the final number of articles selected for your PICO question.
3. Full points for the main issues section of the rubric will be given for including the reasons for the exclusions in your initial post
4. Inclusion of all the final articles is required in the reference section
Submission Instructions:
. Your initial post, question 2, should be at least 250 words, formatted and cited in the current APA style.
. Provide support for your work from at least five academic sources, less than 5 years old. Visit Purdue OwlLinks to an external site. for specific examples on how to create in-text citations and cite references using the current APA format.
. Students will use this PICO question when creating the abstract and academic poster.
. Students may not duplicate the PICO question of another student at St. Thomas University.
. Your initial post is worth 8 points.
. You should respond to at least two of your peers by extending, refuting/correcting, or adding additional nuance to their posts. Your reply posts are worth 2 points. (1 point per response)
. All replies must be constructive and use literature where possible
