Diagnostics & Procedures Flashcards
4 steps to conducting assessments
(Groth-Marnat 2009)
Don’t Run! Down Kujo! Good Dog, give a BONI Inside
Don’t Run!
(Groth-Marnat 2009)
Conducting assessment: Develop a Referral question (working hypothesis) including emotional, cognitive, neurological, physiological, behavioral issues
Down Kujo!
(Groth-Marnat 2009)
Conducting assessment: Develop the Knowledge of empirical findings to make clinical judgements (Garb 1998), applicability to individual situation
Good Dog!
(Groth-Marnat 2009 )
Conducting assessment: Gather Data.
Inside!
(Groth-Marnat 2009)
Conducting assessment: Interpret the Results/Findings including feedback in understandable terms, answer referral question, confidence intervals/descriptors, generalize to bx outside testing
Mrs. Defeats
(Chethik 2003) Behavior Observations: Motor Functioning Reaction to testing Speech Distress level Effort/motivation Frustration Tolerance Emotion/affect Thought processes States (temporary)
DREAMS
(PDM 2006) Psychosocial Histories: Developmental milestones Relationships with others Early childhood bx Across settings, functioning Mental/Medical history Substance use hx
Types of Validity
(Kazdin 2017) Content Criterion Construct (also Face)
Content Validity
(Kazdin 2017)
What do experts believe is being measured?
Least quantitative form
Inter-rater reliability (Kappa)
Criterion Validity
(Kazdin 2017)
Does the measure appropriately predict what it should?
Concurrent: correlates with other measures given at the same time
Predictive
Known Groups
Construct Validity
(Kazdin 2017)
Extent to which the construct being suggested is actually being measured
Convergent/Divergent
Discriminant
Internal Structure (factors) (usually poor when not theory driven)
Incremental Validity
(Kazdin 2017)
Does the measure increase the predictive ability of an existing method
Ecological Validity
(Kazdin 2017) does it measure real-world phenomena (not external validity, which is generalizability)
CASTI
Reliability/consistency of a measure Cronbach's Alpha (internal) Alternate forms Split-Half Test-retest Inter-rater
Projective vs. Objective
(Masling 1997)
Objective: has high face validity, can be faked, defensiveness can affect it
Projective: better predictors of long-term bx, harder to fake
IQ over the lifetime
(Anastasi & Urbina 1997)
Stable from age 8-college, peak at 20-34, is descriptive rather than explanatory
CTONI-II
(Hammill et al, 2009)
Comprehensive Test of Nonverbal Intelligence
Good for those where other tests are inappropriate
ages 6-90:11
SB5
(Roid 2003) Based on the CHC theory Developed using item response theory Ages 2-85+ Reliability of FSIQ .98 Reliability of NVIQ .95 Reliability of VIQ .96 Reliability of ABIQ .91 Factor reliabilities .90 - .92 Validity compared to Wechslers .78 - .84
WAIS-IV
(Wechsler 2008)
Internal Consistency FSIQ .97-.98
Concurrent Validity with WIAT-III .59-.82
Resistant to depression/anxiety (Lezak 1995)
