week 1 Flashcards
Psychological Assessment
a processes that uses both nomothetic and ideographic means to understand a subject and their behavior in context;
Goal of Psychological Assessment
to guide treatment planning
inform decision-making about the client
help the client understand themself in a way that ameliorate the problems in their life
Nomothetic
part of variance in a quality that is shared by people
Idiographic
part of variance that is unique to the individual
traditional objective tests
structured stimulus (a specific statement)
limited set of externally provided answers (true/false, likert scale)
does not rely on scorer’s judgment to classify the response (scored according to a preexisting key)
objective tests ignore …
the test takers willingness to be honest/malingering
test takers lack of self knowledge, response style, halo effect and scapegoating effect
imperfections in the test (ambiguity, psychometrics etc)
replaced objective tests
self-report tests
can be differentiated by type of informant (self typically) but also can be parent questionnaire, spouse questionnaire, teacher questionnaire etc
Projective tests
refers to ambiguous stimulus or activity (inkblot)
test takers generate a response with minimal guidance; puts forward elements of their habits and personality; interpretation requires subjectivity
which test fits classical definition of projective tests and why
rorschach inkblot method
ambiguity and infinite answers
Rorschach scoring
involves stimulus classification and problem solving styles more than projection
scoring strictly limits subjectivity
modified use of projective tests
we distinguish between two types
1) projective tests
2) performance based personality tests
projective tests (type)
rely exclusively on projection (house-tree-person, thematic apperceptions tests, Roberts picture story)
Performance based personality tests
have substantial nomothetic aspects
Rorschach, Wartegg Drawing Completion, Adult attachment projective
Attributes of a good test
clear instructions for administering, scoring, and interpreting
efficient use (incremental validity)
accurate
- reliability: consistency
- validity: measures what its supposed to
Purpose of personality assessments
- describe current functioning
- confirm, refute or modify impressions
- Identify therapeutic needs
- aid in differential dx
- monitor treatment
- manage risk
- effective short term therapeutic intervention
- guard against bias/human thinking errors
