Study Notes

Validity

Validity refers to the extent a test measures what it intends to measure.
It considers the appropriateness, meaningfulness, correctness, and usefulness of researcher inferences.
Example: An IQ test measuring intelligence, a tape measure measuring head circumference as a measure of intelligence is not valid.

Content Validity

Examines test content to ensure it represents the behavior domain being measured.
Analyzes the behaviour and ensures major aspects are covered proportionally.

Content Validity: Elements/Aspects

Adequacy of the sampling & format (clarity, printing size, workspace).
Appropriateness of language, clarity of directions.

Content Validity: Procedure

Define the behavior/trait to be measured.
Provide the instrument's definition and target population to judges.
Judges check if items measure the target trait, and mark items that don't.
Judges assess item appropriateness and correct any flagged items.
Ensure sufficient/adequate number of items and representative of the construct.

Content Validity: Questions

Does the test cover a representative sample of the needed skills?
Does test performance avoid irrelevant variables?

Test Specifications

Indicates the content areas, topics, and instructional objectives.
Includes the number of items per topic.

Consultation with Subject Matter Experts

Involves seeking knowledge and competency from topic experts.
Specifies the experts' qualifications, dates, and procedures for consultation.

Check Total Score and Progress

Check the total score on a test and individual item performance to assess progress

Face Validity

Refers to whether a test "appears valid" to measure what was intended.
Relevant if the test item formulation appears related to the context.

Criterion Validity

When test scores are compared against other criterion measures.
If results match up with other known measures of a characteristic, it's valid.
Measures the relationship between scores using a given instrument against scores using other valid instruments
Criterion is a second test or procedure measuring the same variable.

Criterion Validity: Examples

Academic achievement; school grades, achievement test scores.
Special honors and awards, amount of education.
Job performance (instructor's ratings, formally assigned grades, completion training).
Psychiatric diagnoses (based on observation, detailed case history).

Types of Criterion Validity: Concurrent Validity

Degree to which a test correlates with a criterion set up as a valid measure.
The test scores are related to another established test given around the same time.

Types of Criterion Validity: Predictive Validity

Measure of how well the test predicts abilities and future performance.
Testing a group, then comparing results at a later date.

Construct Validity

The extent the test measures a theoretical construct or trait.
Examines if the results fit the underlying theories established with the test design.
Does the test produce results aligned with the theories?

Construct Validity: Example

A test of computation should yield higher scores with intensive training.

Factors Influencing Validity

Inadequate sample, improperly intended items.
Poor arrangement, ambiguous directions, improper administration.
