Chapter 4 - Clinical Assessment and Diagnosis Flashcards
psychological assessment
procedure by which clinicians, using psychological tests, obsrvations, and interviews, develop a summary of the clients symptoms
clinical diagnosis
the process through which a clinicial arrives at a gneral “summary classification” of the patient’s symptoms by following a clearly defined system (such as the DSM)
presenting problem
major symptoms and behavior the client is experiencing
what types of information are part of the social or behavioral history?
personality factors and the social context
dysrhythmia
irregular pattern in the brain’s electrical activity
EEG
electrodes on the scalp record brain’s electrical activity
CAT scan
x-rays of the brain
(more structural than functional)
MRI
sharper images of the interior of the brain. does not submit patient to radiation
(more structual than functional)
PET scan
measures metabolic processes to appraise how well an organ is functioning
(more functional than structural)
fMRI
measures changes in blood flow in specific areas of brain tissue
(both structural and functional)
aphasia
a disorder in which there is a loss of ability to communicate verbally
limitations of fMRI
- sensitive to inacuracies due to slight movement of the patient
- results may be difficult to interpret
neuropsychological assessment
measuring a person’s cognitive, perceptual, and motor performance as clues to the extent and location of brain damage
Brief Psychiatric Rating Scale (BPRS)
objective method of rating clinical symptoms that provides scores on 18 variables
useful in clinical research, less so in diagnosis or treatment
Hamilton Rating Scale for Depression (HRSD)
similar to BPRS, but more specifically targeted. Most widely used procedure to select depressed people for clinical research
