PSYB32H3 Chapter 4: Chapter 4 Notes
Document Summary
Test-retest reliability: extent to which ppl being observed perform taking the same test twice, sometimes weeks apart. Alternate-form reliability: patients are tested twice but with 2 different types of tests, in case they aim for consistency and try to mimic the same answers as their previous test when given test-retest reliability. Inter consistency reliability: asses whether the items on a test relate to one another. A person with anxiety who says yes to dry mouth should also say yes to muscle tension. Generally related to whether a measure fulfills its intended purpose. Note that validity is related to reliability: unreliable measures will not have good validity. Content validity: refers to whether the measure adequately samples the domain of interest. Ex: axis i diagnostic test has high content validity because it asks questions about all the symptoms involved in axis i diagnosis.
