Flashcards: Psychometric Foundations and Test Development — 20 cartões

Latent construct — definition?

Unobservable psychological variable inferred from responses.

Observable behavior — role?

Provides data to infer latent constructs.

Implicit Association Test — purpose?

Measures latent biases via response speed and accuracy.

Psychological trait — example?

Intelligence, personality, prejudice.

Operational definition — function?

Links latent traits to measurable responses.

Reliability — what?

Consistency of test scores over time or forms.

Validity — meaning?

Test measures what it claims to measure.

Test bias — effect?

Different item functioning across groups, unfairness.

Cross-cultural validation — purpose?

Ensures fairness and validity across cultures.

Score sensitivity — importance?

Detects meaningful differences or changes.

Classical Test Theory — core idea?

Observed score = true score + error.

True score — what?

Actual, unobservable level of the trait.

Item characteristic curve — depicts?

Response probability as a function of trait level.

Item difficulty — indicates?

Trait level where 50% respond correctly.

Item discrimination — reflects?

Effectiveness at differentiating trait levels.

Test blueprint — purpose?

Guides content, ensures alignment with goals.

Item writing guidelines — aim?

Create clear, relevant, fair test items.

Content validity — what?

Items represent the construct comprehensively.

Pilot testing — role?

Refines items through small sample feedback.

Item analysis — purpose?

Evaluates item quality via difficulty, discrimination.
