Chapter 5 - Validity Flashcards
Definition please:
What does content validity refer to?
The degree to which the items on a psychological test are representative of the construct being measured.
It emphasizes the relevance and adequacy of test items, particularly in achievement tests.
Defintion please:
What is the significance of criterion-related validity?
It refers to the degree to which a psychological test effectively predicts specific external outcomes or behaviors.
This type of validity is essential for establishing the test’s usefulness in forecasting significant social indicators, such as academic success and mental health.
Definition please:
Define concurrent validity.
The degree to which a test correlates with a criterion measure when both are administered at the same time.
It reflects the test’s ability to accurately assess a behavior or characteristic as indicated by the simultaneous measurement of the criterion.
Definition please:
What does predictive validity assess?
The extent to which test scores accurately forecast outcomes on external criteria relevant to the construct being measured.
This form of validity must be supported by empirical evidence rather than anecdotal claims.
True or False: Content validity is sufficient for broader assessments requiring predictive validity.
False.
Content validity focuses on relevance and adequacy, which may not cover all aspects needed for broader assessments.
Definition please:
What is criterion-related validity?
The degree to which a psychological test effectively predicts specific external outcomes or behaviors.
Definition please:
What is incremental validity?
The additional predictive power that a new test or assessment provides beyond existing measures.
Definition please:
Describe the regression approach.
A statistical method used to assess predictive validity by analyzing the relationship between test scores and corresponding criterion measures.
Definition please:
What does diagnostic accuracy refer to?
The effectiveness of a psychological test in correctly identifying and predicting significant social outcomes.
Definition please:
Define sensitivity in the context of psychological tests.
A test’s ability to correctly identify those individuals who possess the attribute or condition being measured.
Definition please:
What does specificity measure?
A test’s capacity to correctly identify those who do not possess the attribute or condition.
Definition please
What is the decision-theoretic approach?
A framework for evaluating the validity of psychological tests that emphasizes the significance of classification errors.
Defintion please
Define construct validity.
The degree to which a psychological test accurately measures the hypothetical constructs it intends to assess.
Definition please:
What is convergent validity?
The extent to which different measures or methods that are supposed to assess the same construct yield similar results.
Definition please
Define discriminant validity.
The aspect of validity that ensures the distinction between different constructs being measured by a test.
Definition please:
What is the Multitrait-multimethod matrix?
A methodological tool used to assess the validity of psychological tests by evaluating convergence and distinguishing between constructs.

What does factor analysis do?
Identifies underlying relationships among a set of observed variables by summarizing their intercorrelations into fewer latent factors.
