Assessment Flashcards
(25 cards)
Assessment process: how it happens
Clinical Interview
Observation
Testing
Observation:
Informal - just observing the person, what are they doing how they dress, etc
Behavioral/Functional Assessment - more formal; figuring out reasons for a reason
Norcross, Hedges, & Castle (2002)
Division 29 (psychotherapy) 96% of profs. spend 54% of time in clinical interview 60% of profs spend 13% of time personality testing
Intake interview
gathering info. on an individual; symptom cultural, background, heredity etc
Diagnostic Interview - Structure Interviews
structured clinical interview for DSM (the SCID)
Diagnostic Interview - Unstructured and Semi-structured Interviews
most common. Not following guidelines except for clinical training
Example of when to use structured interviews?
Research
Crisis Interviews
If necessary. Harmful to self or/and others. Hospitalization
Psychological Assessment Standards
Reliability (consistency)
Validity (accuracy)
Standardization
Test-Retest Reliability
estimates reliability across time. estimate correlation co-efficient (.70 - research; .85 - clinical)
Internal Consistency
Consistency within inventory or research procedure. Do all the items measure the SAME THING. Alpha; same standards as correlation co-efficient
Inter-rater Reliability
rating and observations esque scales. NO SELF REPORT METHODS. Same type of interpretations form different observers. Kappa (.5 for research; .7 for clinical)
Why is validity so essential for those in our profession?
most if not ALL of the ideas and topics we discuss are CONSTRUCTS. we believe these things exist but they actually only do because we define them
Content Validity
an expert goes through the inventory and determine if it is correct. No statistical measure
Construct Validity
statistically done. measures correlations to determine if an inventory correlates the way it should given how we define the construct
Convergent and Divergent Validity
Convergent Validity
does an inventory correlate with other variables. the strengths should go in a certain order
Divergent (Discriminatory) Validity
should not correlate at all. for example depression and intelligence
Criterion-related/predictive validity
does it predict something that it should predict. for example: an inventory measuring Major Depressive Disorder should be able to discriminate those with MDD and those without it. measure in ANOVA’s (f)
Empirical Approach to Test Construction
researchers will look at reliability and validity prior to even developing the test. ex - the Padua inventory
Standardization
Importation of normative data in interpretation. Means, standard deviation, etc. Important to ensure measures are scored the exact same way every time (think of the SAT)
Objective Tests
Measures individual’s characteristics independent of rater bias and beliefs
Multiple Scale Inventories
Inventories such as the MMPI-2, MCM-III, and the SCL-90-R
Single Symptom Disorder Scales
Inventories such as the Beck Depression Inventory, and the Padua
Minnesota Muliphasic Personality Inventory
MMPI-2 most researched and widely used. Contains several validity scales
