LSP Psychological Assessment & Testing — Questions and Answers
Question 1: What is the difference between reliability and validity in psychological testing?
- Reliability measures consistency of results; validity measures whether the test measures what it claims to measure (Correct answer)
- They are the same concept
- Reliability is more important than validity
- Validity refers to test length
Correct answer: Reliability measures consistency of results; validity measures whether the test measures what it claims to measure
Reliability ensures consistent results across administrations, while validity confirms the test actually measures the intended psychological construct. A test can be reliable without being valid.

Standardized tests follow consistent administration procedures and scoring methods, with results interpreted by comparing to normative data from representative samples.

Correct answer: Ensuring clients understand the purpose, procedures, limits of confidentiality, and use of test results before assessment begins
Informed consent requires psychologists to explain what the assessment involves, why it is being conducted, how results will be used, confidentiality limits, and the client's right to decline participation.
