Question 1

A randomized controlled trial (RCT) is considered the 'gold standard' for evaluating treatment effectiveness because:

Accepted Answer

Random allocation controls for confounding variables, allowing causal inference

Answer

Random allocation to treatment groups controls for known and unknown confounders, allowing causal conclusions about treatment effectiveness.

Question 2

Number Needed to Treat (NNT) is a clinical statistic representing:

Accepted Answer

How many patients must be treated to produce one additional positive outcome compared to control

Answer

NNT is the inverse of absolute risk reduction, indicating how many patients need treatment for one to benefit compared to control.

Question 3

In the ICF (International Classification of Functioning, Disability and Health) framework, 'activity limitations' refer to:

Accepted Answer

Difficulties an individual has in executing tasks or actions

Answer

ICF's activity domain covers difficulties executing tasks, distinguishing it from impairments (body structures/functions) and participation restrictions.

Question 4

A CMT uses the Global Rating of Change (GROC) scale to measure:

Accepted Answer

Patient's self-reported perception of overall change since baseline treatment

Answer

The GROC is a patient-reported scale capturing the patient's perception of their overall change since beginning treatment, ranging from 'much worse' to 'much better.'

Question 5

Which bias occurs when patients or clinicians know which treatment group a patient is in, potentially affecting reported outcomes?

Accepted Answer

Performance and detection bias

Answer

Performance bias (altered care due to group knowledge) and detection bias (altered outcome assessment) both arise when blinding is absent.
