Fill-in-the-blank item (Validity and Reliability—Terminology)
Item stem: The degree to which an instrument yields consistent scores for the same respondents when administered on two separate occasions, assuming the construct has remained stable, is termed ______ reliability.
Correct answer: test–retest reliability
Acceptable alternatives for scoring: stability reliability; temporal stability
Scoring guideline: 1 point for the correct answer or listed alternatives. Do not award credit for other forms of reliability (e.g., internal consistency, inter-rater, parallel-forms) or for the generic term reliability.
Rationale: Reliability concerns the consistency or precision of measurement, and the test–retest approach specifically evaluates temporal stability by correlating scores from two administrations separated by an appropriate interval during which the construct is not expected to change (AERA, APA, & NCME, 2014; DeVellis & Thorpe, 2021; Cohen, Swerdlik, & Sturman, 2018).
