Which concept refers to the consistency of a result across different parts of a personality test?

Internal validity
Internal reliability
External reliability
External validity

The correct answer is: Internal reliability

The concept that refers to the consistency of a result across different parts of a personality test is internal reliability. Internal reliability assesses whether various items on a test that are intended to measure the same construct yield similar results. High internal reliability indicates that the test items are effectively measuring the same concept, suggesting that the test is coherent and the results are trustworthy. In the context of personality tests, if multiple questions or sections intended to measure traits such as extraversion or conscientiousness produce consistent results, it signifies that the test is reliable. This is crucial for psychologists and researchers who rely on personality assessments to make informed conclusions about an individual's personality traits. On the other hand, internal validity pertains to the extent to which the test accurately measures what it intends to measure, while external reliability refers to the consistency of test results over time or across different populations. External validity concerns the generalizability of the test results to other settings or populations. Each of these concepts plays a role in the overall assessment but internal reliability specifically focuses on the consistency within the test itself.
