Evaluating Outcomes Flashcards
What is the main aim of psychometric testing in clinical psychology?
To evaluate constructs such as cognitive abilities and emotional wellbeing
Constructs refer to the underlying traits or characteristics that psychometric tests seek to measure.
What are the key constructs measured in neuropsychological assessments?
- Attention
- Orientation
- Perception and/or visuospatial skills
- Speed of processing
- Memory
- Language
- Praxis
- Executive function
These constructs help identify cognitive difficulties linked to neurological conditions.
What does the Montreal Cognitive Assessment (MoCA) measure?
Detects mild cognitive impairment
MoCA provides a score out of 30, with <26 indicating cognitive impairment.
What is the sensitivity of the MoCA for detecting mild cognitive impairment compared to the MMSE?
MoCA: 90% sensitivity; MMSE: 18% sensitivity
Sensitivity refers to the test’s ability to correctly identify those with the condition.
What does the term ‘psychometrics’ refer to?
The field focused on building and evaluating psychological tests
Psychometrics ensures that tests are reliable and valid.
What are the types of validity in psychometric testing?
- Face validity
- Construct validity
- Concurrent validity
- Predictive validity
Each type assesses different aspects of how well a test measures what it claims to measure.
What is reliability in the context of psychometric testing?
The consistency of test results across multiple administrations
Reliability can be assessed through test-retest, inter-rater, internal consistency, and parallel versions.
What are the potential consequences of incorrect psychometric testing?
- Wrong neurological diagnosis
- Understated symptoms leading to lack of help
- Mislabeling due to language barriers
Incorrect testing can have significant impacts on patient care and treatment outcomes.
Fill in the blank: The MoCA is often used as a quick measure for excluding cognitive impairment in research samples due to its good _______.
psychometric properties
Psychometric properties refer to the reliability and validity of the assessment.
True or False: The MMSE has a higher sensitivity for detecting mild Alzheimer’s disease than the MoCA.
False
The MoCA detected 100% of mild Alzheimer’s disease cases, while the MMSE detected 78%.
What is the importance of cultural considerations in psychometric testing?
Cultural context can affect test performance and interpretation
Understanding cultural differences is crucial to avoid biases in testing outcomes.
What are the common types of tests used in UK school culture and healthcare?
- SATS
- GCSEs
- A levels
- Personality tests
- Cognitive tests
- Emotional wellbeing tests
These tests play significant roles in determining educational and healthcare outcomes.
What is the role of a clinical psychologist in neuropsychology?
To understand and use clinical outcome measures
Clinical psychologists often work with neurological conditions and patient care.
What is the significance of the statement: ‘a test can be reliable but not valid’?
It indicates that a test may consistently produce the same results, but those results may not accurately measure what they are supposed to
This highlights the importance of both reliability and validity in test development.
What does the term ‘norms’ refer to in psychometric testing?
A baseline distribution taken from a large, representative sample
Norms help compare an individual’s test performance to that of their peers.
What kind of qualitative information can neuropsychological tests provide?
Information about cognitive problems, their effects, and potential interventions
This qualitative data is crucial for tailoring treatment plans.
What is the purpose of administering tests in a controlled environment?
To allow the client or participant to perform at their best
Controlled conditions help minimize external factors that could affect test outcomes.
What is the recommended cut-off score for the Montreal Cognitive Assessment (MoCA)?
26
Four studies indicated this cut-off for assessing dementia.
What is the sensitivity and specificity of MoCA at the cut-off score of 26?
High sensitivity of 0.94 or more; low specificity of 0.60 or less
What is the implication of the overall quality and quantity of information regarding MoCA?
Insufficient to make recommendations on the clinical utility of MoCA for detecting dementia
What is required for optimal diagnostic utility of MoCA?
Further good-quality studies applying diagnostic tests and reference standards prospectively are required
What common neuropsychological assessment evaluates visual attention and task switching?
Trail-making test
What cognitive abilities does the trail-making test assess?
Visual attention, visuomotor skills, cognitive flexibility, speed of processing, visual search speed
Problems on the trail-making test may indicate issues with which part of the brain?
Frontal lobe lesions
What does the figure copy task evaluate in neuropsychological assessments?
Holistic and piecemeal processing of visual information
What scoring criteria are used for the figure copy task?
Drawing must be three-dimensional, all lines drawn, lines parallel, similar length
What is a potential issue when assessing a person with neurological symptoms in figure drawing tasks?
Coordination and muscle movements may affect performance
What alternative rapid screening test for dementia is mentioned?
Cube drawing alone as a rapid screening test
What factors can affect performance on 3D drawing tasks?
Prior learning, past experience, job, culture
What cultural differences may impact visual material processing?
People from different cultures may process visual material differently, e.g., US vs. Aboriginal cultures
What does the clock drawing task evaluate?
Visuoconstructive skills
What are the scoring criteria for the clock drawing task?
Contour, correct numbers in order/locations, correct hands
