What is the Boolean operator OR used for - ANSWER Broaden searches
What is the Boolean operator AND used for - ANSWER Narrow searches
Are Boolean operators used in PEDro - ANSWER No, asterisks are used instead
What are important considerations for Google Scholar and PEDro - ANSWER Do not use too many
keywords, may have to extrapolate the search terms used in PubMed
When should you use PEDro - ANSWER When searching for higher level study designs such as systematic
reviews, meta-analyses, and randomized control trials specific to PT interventions
When should you use Google Scholar - ANSWER When searching for systematic reviews or meta-
analyses across all units
What are true experiments/randomized control trials - ANSWER Random allocation, best for controlling
bias, gold standard for establishing causation but excessive control may overshadow clinical relevance
What are quasi-experiments - ANSWER Non-randomized and may or may not be controlled, more
vulnerable to bias but may be more clinically relevant, especially useful when randomization is not
possible
What are pre-experiments - ANSWER Non-randomized and no control, much more vulnerable to bias,
may serve as pilot studies or real-world impact evaluations
What are non-experimental/observation designs - ANSWER Most vulnerable to bias but may be clinically
relevant and common in pragmatic research approaches

What is a confounding variable - ANSWER A variable that distorts the relationship between the
independent and outcome variables and contribute to a change in outcome measures
What is randomization - ANSWER A random process used to generate the sequence for allocating
participants to groups
What is allocation concealment - ANSWER The allocation of participants to a study group is concealed
until the participants are enrolled in the study and assigned to a group, people recruiting participants as
well as the participants should not know the group assignments
What is blinding/masking - ANSWER
What is the role of chance - ANSWER Even with random assignment, it is possible by chance to have
unbalanced groups on a prognostic variable that may influence the outcome
What happens if sample size is too small - ANSWER Some randomization techniques can result in
unequal group sizes
What is intention to treat/ITT - ANSWER Outcome data is collected and analyzed as such regardless of
how well the patient completes the treatment
How does ITT reduce bias - ANSWER It maintains the benefits of randomization
What is per-protocol analysis - ANSWER Outcome data is only used for those who complied with the
treatment
How is bias reduced during recruitment of participants - ANSWER Allocation concealment
How is bias reduced during assignment of participants to groups - ANSWER Random assignment
