- Refers to the extent to which the findings are valid over time.
- Refers to the extent to which a study appears to measure what it claims to measure.
- Refers to the extent to which the results and conclusions are generalisable to real life.

Study Notes
Internal Validity
- Measures how accurately an experiment assesses the dependent variable.
Ecological Validity (External Validity)
- Assesses the generalizability of study findings to real-life scenarios.
Population Validity (External Validity)
- Evaluates how well the sample represents broader populations.
Temporal Validity
- Considers the validity of findings over time, accounting for changes and developments.
Face Validity
- Determines if a study seems to measure what it claims at first glance.
Construct Validity (Test Validity)
- Encompasses two aspects:
- Convergent Validity: Assesses the relationship between related constructs.
- Discriminant Validity: Tests that unrelated constructs do not show any relationship.
Content Validity (Test Validity)
- Evaluates whether a study or test measures all aspects of a concept comprehensively.
Criterion Validity
- Compares study results and conclusions to other measures for validation.
Predictive Validity
- Assesses the ability of findings to forecast real-life outcomes or applications.
Concurrent Validity
- Examines whether study results align with findings from other related studies.
Statistical Conclusion Validity
- Ensures results are statistically significant, establishing cause and effect beyond mere chance.
Representation Validity (Translational Validity)
- Evaluates how well the studied construct can be applied to real-world situations.
Diagnostic Validity
- Assesses the accuracy of a diagnosis concerning a specific condition.
Instrumental Validity
- Evaluates the appropriateness of tools used to measure dependent variables for accuracy.
