Cognitive
reliability
consistency of measurement.
two components of reliability
Sensitivity - agreement regarding the presence of a particular diagnosis
Specificity - agreement concerning the absence of a particular diagnosis
Inter-rater reliability
refers to the degree to which two independent observers or judges agree.
Test-retest reliability
measures the extent to which people being observed twice or taking the same test twice score in generally the same way.
Construct validity
Is the test measuring what it claims to test?
Criterion Validity
How predictive is the test? If you took the Beck Depressive Inventory, but a psychiatrist says that you do not appear to have symptoms of depression, then the Beck Depressive Inventory does not have Criterion Validity
Unstructured Clinical Interviews
rely on the intuition and general experience of the interviewer. Low reliability
Structured Interviews
An interview where the questions are set out in a prescribed fashion for the interviewer.
Used when mental health professionals need to collect standardized information, particularly for making diagnostic judgments based on the DSM.
Structured Clinical Interview Diagnosis (SCID)
Uses branching: the client’s response to one question determines the next question that is asked.
Psychological Tests
Psychological tests are standardized procedures designed to measure a person’s performance on a particular task or to assess his or her personality, or thoughts, feelings, and behaviour.
Personality Inventories
The person is asked to complete a self-report questionnaire indicating whether statements assessing habitual tendencies apply to him or her. (EX Minnesota Multiphasic Personality Inventory, MMPI).
Projective Personality Tests
a psychological assessment device in which a set of standard stimuli, ambiguous enough to allow variation in responses, is presented to the individual (Rorschach Inkblot Test)
Intelligence Tests
Alfred Binet, originally constructed mental tests to help the school board predict which children required special schooling.
Computerized axial tomography (CT scan)
A moving beam of X-rays passes into a horizontal cross-section of the client’s brain, scanning it through 360 degrees; the moving X-ray detector on the other side measures the amount of radioactivity that penetrates, thus detecting subtle differences in tissue density
Functional Magnetic Resonance Imaging (fMRI)
providing a picture of the brain at work rather than of its structure alone.
