Week 5 Flashcards
Why Restructure the Clinical Scales?
“While they contain compelling informative items, it has long been recognized that as aggregate measures the Clinical Scales are not psychometrically optimal:”
- Higher than expected intercorrelations
- Substantial item overlap
- Heterogeneous, over-inclusive item content
wanted to take out demoralization, was too heavily influencing everything
The Restructured Clinical Scales
Removed the pervasive negative emotionality from the clinical scales in order to get cleaner scales
The expectation was that the restructured clinical scales would be more clinically distinct than the original Clinical Scales.
New RCD Scales
**AKA took out unhappiness from scales
Ex. RC2 is depression without unhappiness
RC3 is hysteria without unhappiness
RCD “Demoralization” factor (Negative Emotionality)
RC1 Somatic Complaints,
RC2 Low Positive Emotions
RC3 Cynicism
RC4 Antisocial Behavior
RC5A *Aesthetic/Literary Interests
RC5M *Mechanical/Physical Interests
RC6 Ideas of Malevolence
RC7 Dysfunctional Negative Emotions
RC8 Aberrant Experiences
RC9 Hypomanic Activation.
no restructured scale for Si–because it was not as permeated with demoralization factor.
MMPI-2 RC Scales: Psychometrics
MORE PURE
Tellegen et al. (2003) present data from several clinical samples documenting that in comparison with their Clinical Scale counterparts, the RC Scales show:
Comparable or improved reliability
Substantially reduced saturation with Demoralization
Substantially reduced inter-correlations
Comparable or improved convergent validity
Substantially improved discriminant validity
