Clinical Utility

How useful a test is for diagnosing or assessing clinical conditions.

application: Selecting appropriate assessments for diagnosing mental health conditions.

situation: Using the MMPI to diagnose personality disorders in a psychiatric clinic.

Diagnostic Utility

The ability of a test to classify individuals into categories (e.g., presence or absence of a condition).

application: Using screening tests to identify individuals with specific mental health issues.

situation: Applying the Beck Depression Inventory to identify symptoms of clinical depression.

Psychometric Soundness

The degree to which a test is reliable and valid for its intended use.

Costs

The financial and resource-related expenses associated with administering a test.

Benefits

The advantages or gains from using a test, including better decisions and improved outcomes.

application: Assessing whether a test reduces errors in candidate selection or increases productivity.

situation: Evaluating how a new cognitive assessment improves student placement accuracy.

Utility Analysis

A cost-benefit analysis technique used to evaluate the practical value of an assessment.

application: Used to determine whether adopting a new test is financially and practically worthwhile.

situation: Conducting a utility analysis to compare the efficacy of two intervention programs.

Expectancy Data

Information showing the likelihood that a test-taker will achieve a specific outcome.

application: Predicts how well individuals will perform based on their assessment scores.

Brogden Cronbach-Gleser Formula

A statistical method to estimate the utility of a test by calculating productivity gains.

application: Used in personnel selection to predict the economic impact of hiring decisions.

Cutoff Scores

Reference points that classify individuals into categories based on their test performance.

application: Applied to pass/fail decisions in academic testing and clinical diagnosis.

situation: Setting a cutoff score of 70% on a knowledge test to certify professionals.

Relative Cut Score

A cutoff score based on norm-related considerations (how a test-taker performs relative to others).

application: Used in competitive selection processes where only top performers are accepted.

situation: Admitting the top 10% of candidates based on their exam scores.

Fixed Cut Score

A predetermined score that defines minimum competency or proficiency.

application: Applied in licensing exams where a specific score is required to pass.

situation: Requiring a score of 75% to pass a clinical psychology licensing exam.

Multiple Cut Scores

Using two or more cut scores for classifying test takers into multiple categories.

application: Applied in tiered classification systems like academic grading or job suitability.

situation: Categorizing job applicants into “highly qualified,” “qualified,” and “not qualified.”

Multiple Hurdle Model

A selection method where applicants must pass several independent criteria to qualify.

application: Used in high-stakes job recruitment where multiple competencies must be verified.

Compensatory Model

where high performance on one criterion can offset low performance on another.

application: Applied when overall potential is more important than individual weaknesses.

Angoff Method

where experts estimate how minimally competent individuals would perform on each test item.

application: Used to set pass/fail thresholds in professional certification exams.

situation: Setting a passing score for the bar exam through expert judgment.

Known Groups Method

Establishes cut scores by comparing test performance between groups known to differ on the trait of interest.

application: Applied when validating new diagnostic tools or assessments.

situation: Differentiating between depressed and non depressed patients using a depression scale.

IRT-Based Method

Sets cut scores using item response theory, considering item difficulty and discrimination.

application: Applied in adaptive testing and complex performance assessments.

situation: Setting difficulty-based cut scores in computerized adaptive GRE testing.

Thorndike’s Predictive Yield

A norm-referenced method for setting cut scores to maximize correct classifications.

application: Applied when optimizing classification accuracy in educational and occupational testing.

Discriminant Analysis

A statistical technique to determine which variables best distinguish between predefined groups.

application: Applied to classify individuals based on psychological or performance data.

situation: Identifying personality traits that distinguish successful and unsuccessful employees.
