Chapter 2 Flashcards
alternate-form reliability
the relationship between scores achieved by people when they compete two versions of a test that are judged equivalent.
behavioural assessment
a sampling of ongoing cognitions, feelings and overt behaviour in their situational context.
BOLD (Blood Oxygenation Level Dependent)
the signal detected by functional MRI sutdies of the brain; measures blood flow and thus neural activity in particular regions.
Case conceptualisation
a process of integrating a patient’s assessment information with theory and research.
Categorical classification
an approach to assessment in which a person is or is not a member of a discrete group.
Clinical interview
general term for conversation between a clinician and a patient that is aimed at determining diagnosis, history, cause of problems and possible treatment options.
Comorbidity
the co-occurrence of two disorders, as when a person has depression and social phobia.
Concurrent validity
the extent to which previously undiscovered features are found among patients with the same diagnosis.
Construct validity
the extent to which scores or ratings on an assessment instrument relate to other variables or behaviours according to some theory or hypothesis.
Content validity
the extent to which a measure adequately samples the domain of interest.
Criterion validity
the extent to which a measure is associated in an expected way with some other measure.
CT or CAT scan
refers to computerised axial tomography, a method of diagnosis in which x-rays are taken from different angles and then analysed by a computer to produce a representation of the part of the body in cross-section.
Diagnostic and Statistical Manual of Medical Disorders (DSM)
The manual of clinical syndromes published by the American Psychiatric Association and used for descriptive diagnosis.
Dimensional diagnostic system
an approach to classifying mental disorders that involves considering symptoms, behaviours and characteristics on a continuum, rather than assigning them to a category.
Ecological momentary assessment (EMA)
form of self-observation involving collection of data in real time (e.g. diaries) regarding thoughts, moods and stressors.
Electrocardiogram (EKG) a
recording of the electrical activity of the heart, made with an electrocardiograph
electrodermal responding
a recording of the minute electrical activity of the sweat glands on the skin, allowing inference of an emotional state.
electroencaphalography
a recording of electrical activity of the brain, usually of the cerebral cortex, but sometimes the lower areas.
functional magnetic resonance imaging (fMRI)
modification of magnetic resonance imaging (MRI) that allows researchers to take pictures of the brain so quickly that metabolic changes can be measured, resulting in a picture of the brain at work rather than structures alone.
internal consistency reliability
the degree to which different items of an assessment are related to one another.
interrater reliability
the relationship between the judgements of at least two raters make independently about a phenomenon.
metabolite
a chemical breakdown product of an endogenous molecule, such as a neurotransmitter, or of an exogenous drug; used to gauge current or recent level of its precursor.
Minnesota Multiphase Personality Inventory (MMPI)
a lengthy personality inventory that identifies individuals with states such as anxiety, depression, masculinity-femininity and paranoia, through their true-false replies to groups of statements.
neuropsychological tests
psychological tests, such as the Luria-Nebraska, which can detect impairment in different parts of the brain.
Predictive validity
the extent to which predictions can be made about the future behaviour of patients with the same diagnosis.
Projective hypothesis
the notion that standard but highly unstructured stimuli, as found in the Rorschach assessment’s series of inkblots, are necessary to bypass defences in order to reveal unconscious motives and conflicts.
