Questions and Answers

Explain three changes in perspective that become the starting point of psychological testing.

Three changes in perspective include: 1) changes in theoretical approaches, 2) advancements in measurement techniques, and 3) the integration of statistical methods in test development.

Differentiate between criterion validity and construct validity using specific examples.

Criterion validity measures how well one variable predicts an outcome based on another variable, while construct validity assesses whether a test truly measures the theoretical construct it's intended to measure. Example: SAT scores (criterion) vs. intelligence scales (construct).

Interpret the test-retest reliability values of 0.10, 0.90, and 0.70.

Test A (0.10) is not reliable, showing poor consistency; Test B (0.90) is highly reliable, indicating great consistency; Test C (0.70) is moderately reliable, suggesting acceptable consistency.

Suggest three tests which are suitable to assess John’s clinical symptoms.

<p>Three suitable tests include: 1) Beck Depression Inventory (strength: effectively measures depression, limitation: self-report may bias results), 2) Generalized Anxiety Disorder 7-item scale (strength: specific for anxiety, limitation: not exhaustive), and 3) Minnesota Multiphasic Personality Inventory (strength: comprehensive personality assessment, limitation: lengthy).</p> Signup and view all the answers
