Reliability
Reliability refers to the consistency, or stability, of a measure or study. In other words, it is the extent to which it can produce the same results under similar circumstances
Generalisability
The extent to which research findings can be applied to people or settings beyond those included in the original study
Population validity
A type of external validity that indicates how well a study’s findings can be applied to the wider population
Social desirability bias
The tendency for people to respond to questions in a way they believe would meet the approval of others
