Study Notes
Construct Validity
- Aims to understand if a theoretical model accurately represents the data
- Focuses on the degree to which a test measures a specific concept, trait, or theoretical entity
- Example: Evaluating if a questionnaire accurately measures aggression, rather than assertiveness or social dominance
- Threatened by factors such as a mismatch between the construct and its operational definition, bias, experimenter effects, and participant reactions
- Has two main subtypes: convergent validity and discriminant validity
Convergent Validity
- Measures the correlation between a measure and other theoretically related measures of the same construct
- High correlation with other established measures suggests strong validity
- Example: A depression scale should correlate highly with other measures of depression
Discriminant Validity (Divergent Validity)
- Focuses on the extent to which a measure does not correlate with measures assessing different, unrelated constructs
- Low correlation with measures of unrelated constructs indicates strong validity
- Example: A depression scale should not strongly correlate with a measure of physical fitness
Content Validity
- Represents the degree to which a test samples the subject matter or behavior being investigated
- Example: A third-grade arithmetic test should represent the full range of arithmetic operations at that level
- Example: A typing test for an administrative assistant role has high face validity, but the same test for a lifeguard role may not
- High face validity can be problematic in areas such as substance abuse and offending behavior, where social desirability may impact responses
Criterion Validity
- Measures how well a test correlates with an established standard of comparison, or criterion
- Three types: predictive, concurrent, and retrospective
- Example: The Short-Form Health Survey (SF-36) assesses health against established measures, demonstrating concurrent validity
Predictive Validity
- Aims to predict future outcomes
- Example: A measure predicting future health outcomes
Concurrent Validity
- Measures a test against an established standard of comparison at the same time
- Example: SF-36 measuring health against established measures at the same time
Retrospective Validity
- Examines the relationship between a measure and a criterion that happened in the past
- Example: A measure assessing past experiences related to a specific outcome
Practice Effects
- Changes or improvements in performance resulting from repetition of tasks or activities
- Particularly relevant in within-subjects designs, as participants' improvement may be due to repetition rather than the study manipulation
Face Validity
- The degree to which an assessment tool appears to measure what it intends
- Example: A test directly measuring aggression may be straightforward but could lead to participants suppressing their true aggression
- An indirect assessment tool may allow for interpretation of patterns in suppressed aggression, but could be misinterpreted by participants
Validity Overview
- Face Validity: Apparent appropriateness of the assessment tool
- Criterion Validity: Consistency with a relevant measure
- Construct Validity: Adequacy of the assessment tool in representing the construct
- Content Validity: Representativeness of the subject matter.
