Chapter 3 Flashcards
Components of Clinical Assessments
Reliability- Consistency of measurement
Validity- Does it measure what it intends
Standardization- Consistency, can it be applied to groups
Mental Status Exam
General overview and observations of patient
5 Categories- Appearance & Behavior, Thought Processes, Mood & Affect, Intellectual Functioning, and Sensorium
Used to personalize testing
Behavioral Assessment
Tracking and identification of target behavior to determine its causes
Focuses on Antecedent, Behvaior, and Consequences
WAIS Subscales
Verbal- Vocabulary, Knowledge of facts, short-term memory, and verbal reasoning
Performance- Psychomotor skills, non-verbal reasoning, and learning new relationships
IQ
Ability to do well in education system, not a measure of intelligence
Neuroimaging Strategies
Structure- CT scan, MRI
Function- PET, SPECT, or fMRI
Psychophysiological Assessment
Measure changes in nervous system and biomarkers in response to other events
Testing methods- EEG, heart rate, respiration, electro-dermal responding
Idiographic Strategy
Determine what makes a person unique
Nomothetic Strategy
Determine what groups of symptoms a person experiences
Prototypical Diagnostic Approach
Determine essential characteristics of a disorder and several non-essential feature
Need several non-essential, but not all, to render diagnosis
Internal research validity
Does the independent variable cause the change in the dependent variable
Confounding variable
Any variable not controlled for in a study that changes results
AKA third variable
External validity
Generalizability
How well do results translate to the outside world
Analogue Models
Attempt to recreate real-world scenarios in lab to increase external validity
Statistical significance
Mathematical difference between two groups
