Accepted Answer

A systematic review using rigorous, pre-specified, reproducible methods

Cochrane Reviews are systematic reviews conducted using stringent pre-specified protocols to minimize bias and provide the most reliable synthesis of evidence.

Question 3

Which type of validity assesses whether a measurement instrument covers all relevant dimensions of the construct being measured?

Accepted Answer

Content validity

Content validity evaluates whether the instrument's items adequately sample all important aspects of the domain or construct it intends to measure.

Question 4

Hawthorne effect is a threat to which type of validity?

Accepted Answer
