Reliability is affected by many factors, but from the researcher’s point of view, the three most important factors are the length (or total number of questions), the quality of the questions, and the fit to the group being measured.

What can affect reliability in research?

It depends on the nature of the measurement (e.g., focus/attention affects reaction times, hunger/tiredness leads to reduced physical/mental performance, etc.). These participant changes can create error that reduces the reliability (i.e., consistency or stability) of measurements.

These four threats are the Recall Effect, the Spoiler Effect, Longitudinal Selection Bias and Timeline Reliability.

What makes a survey reliable?
