Questions and Answers

What does content validity assess in an assessment tool?

  • The representation of the subject matter or behavior (correct)

    • Construct validity is concerned with which of the following?

  • The ease with which participants can complete the assessment
  • How well the assessment represents the construct being measured (correct)

    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.
