Which study design is considered the gold standard for establishing cause-and-effect relationships in accessibility research?
Answer: Randomized controlled trial (RCT)
RCTs randomly assign participants to conditions, controlling confounds and establishing causality better than other designs.
A CEAC consultant reviews a study where 80% of participants reported improved mobility after a ramp installation. What type of data is this?
Answer: Self-reported subjective data
Participant-reported outcomes such as perceived improvement are classified as self-reported subjective data.
When critically appraising an accessibility study, which element most directly indicates the internal validity of the findings?
Answer: Control of confounding variables
Internal validity depends on how well confounding variables are controlled so observed effects can be attributed to the intervention.
A consultant wants to identify all available evidence on door width standards for wheelchair users. Which approach is most appropriate?
Answer: Conducting a systematic literature review
A systematic literature review uses explicit, reproducible methods to identify and synthesize all relevant evidence on a topic.
In evidence-based practice, after gathering research evidence, what is the next critical step before making an accessibility recommendation?
Answer: Integrate evidence with client values and clinical expertise
EBP requires integrating best available evidence with practitioner expertise and the client's individual values and circumstances.
Which statistical measure is most useful for understanding the practical significance of a research finding in accessibility studies?
Answer: Effect size
Effect size quantifies the magnitude of a difference or relationship, indicating practical significance beyond statistical significance.
A CEAC consultant finds two studies with conflicting conclusions about grab bar placement. What is the best approach?
Answer: Conduct a meta-analysis or consult a systematic review that synthesizes both
When studies conflict, consulting a meta-analysis or systematic review that synthesizes multiple studies provides the most reliable guidance.
