As a therapist preparing for the NBCOT® exam, a solid understanding of research and statistical terminology is critical. This guide dives into the essentials of evidence-based practice and the PICO format, essential for structuring clinical research questions.
Evidence-Based Practice & Its Importance
Evidence-Based Practice (EBP) involves the meticulous use of current, research-based evidence in clinical decision-making. It enhances the validity of therapeutic practices and is easier to justify to stakeholders like patients, physicians, and insurance companies. Here are the basic steps to employ research in practice effectively:
- Formulate a clear clinical question.
- Search for the best evidence in literature, prioritizing current and high-quality research.
- Assess the validity, reliability, and clinical applicability of your findings.
- Apply the evidence to clinical practice decisions.
What is PICO?
The PICO model is a framework to create clear, focused clinical questions that drive effective literature searches and guide evidence-based practice in occupational therapy:
- P (Patient/Population/Problem): Define the patient group or problem.
- I (Intervention): Specify the main intervention being considered.
- C (Comparison): Identify the main alternative to compare, if available.
- O (Outcome): Determine the desired effect or outcome.
This approach is especially useful for structuring queries in evidence-based medicine (EBM) and is foundational in crafting a solid research question.
Example Questions Using PICO
Here are some examples to illustrate PICO questions:
- Scenario 1: For patients with COPD, does using pursed lip breathing, as compared to regular breathing, improve exercise endurance?
- Scenario 2: In recent stroke patients, how does using virtual reality affect balance improvement?
Understanding the PICO Format
To maximize the outcome of your research question using the PICO format, ensure that each component is well articulated. This clarity supports the development of a precise search strategy and facilitates access to relevant and high-quality professional evidence.
Types of Research and Hierarchy of Evidence
Research types are ranked in a hierarchy of evidence, which ascends from qualitative case studies to quantitative meta-analyses of randomized controlled trials. Understanding where different study types fall within this hierarchy will assist in appraising the strength of evidence.
Key Research Terminologies
Grasp critical research terms such as independent and dependent variables, covariation, null hypothesis, and significance level, all of which play vital roles in examining research outcomes and their applications in clinical settings.

What is Evidence-Based Practice (EBP) and why is it important in occupational therapy?
Evidence-Based Practice (EBP) is the use of current, research-based evidence in clinical decision-making. In occupational therapy, it enhances the validity of therapeutic practices and is easier to justify to stakeholders like patients, physicians, and insurance companies.
How does the PICO model assist in formulating clinical research questions?
The PICO model helps in creating clear, focused clinical questions crucial for effective literature searches and guiding evidence-based practice. It involves defining the Patient/Population/Problem, specifying the Intervention, identifying a Comparison, and determining the Outcome.
What are some example PICO questions in occupational therapy?
Example PICO questions include: ‘For patients with COPD, does using pursed lip breathing compared to regular breathing improve exercise endurance?’ and ‘In recent stroke patients, how does using virtual reality affect balance improvement?’
What are the steps to effectively employ research in clinical practice?
To employ research in clinical practice: Formulate a clear clinical question, search for high-quality evidence, assess the validity and reliability of findings, and apply the evidence to practice decisions.
