Assessment: process of gathering information about people’s symptoms and its causes Diagnosis: label for a set of symptoms that occur together Validity: accuracy of a test in assessing what it is supposed to measure - Concurrent validity: test yields the same results as other measures - Predictive validity: test predicts the behavior it is supposed to measure - Construct validity: measures what it is supposed to measure Reliability: indicates consistency in measuring what it is supposed to measure - Test-retest reliability: consistency of results of a test over time - Internal reliability: different parts of the same test produce similar results - Alternate form reliability: two versions produce similar results - Interrater reliability: 2+ judges who score a test come to similar conclusions Personality inventories: questionnaires meant to assess people’s typical ways of behaving. CT - computerized tomography: x ray beams pass through the head from different angles PET - positron-emission tomography: picture of activity in the brain through injecting radioactive isotope MRI - magnetic resonance imaging: no radiation exposure and provides image of brain at every angle EEG - electroencephalogram: measures electrical activity along the scalp by firing specific neurons Projective test: when presented with an ambiguous stimulus (drawing) they will interpret it in line with their current feelings comorbidity: meeting the criteria for another disorder when diagnosed with one.
