Five Factor Borderline Inventory (FFBI)

Mullins- Sweatt, Edmundson, Sauer- Zavala, Lynam, Miller, & Widiger (2012)

1) Anxious Uncertainty

2) Dysregulated Anger

3) Despondence

4) Self-Disturbance

5) Behaviour Dysregulation

6) Affective Dysregulation

7) Fragility

8) Dissociative Tendencies

9) Distrustfulness

10) Manipulativeness

11) Oppositional

12) Rashness

The FFBI subscales were shown to have good internal consistency— Mullins-Sweat, Edmundson, Sauer-Zavala, Lynam, Miller, & Widiger (2012)

The FFBI subscales were shown to have good convergent, discriminant, and incremental validity—Mullins-Sweat, Edmundson, Sauer-Zavala, Lynam, Miller, & Widiger (2012)


Paranoid Personality Disorder Features Questionnaire.

Useda, 2002


1) Mistrust/ suspiciousness

2) Antagonism

3) Introversion

4) Hypersensitivity

5) Hypervigilance

6) Rigidity

The test-retest reliability of the six PPDFQ scores over a 6-week interval was good, and the hypothesised relationships between the PPDFQ subscales and the five-factor model of personality as well as Livesley’s dimensional model of personality pathology were supported—Bernstein & Useda, 2007.




Interpersonal Measure of Schizoid Personality Disorder (IM-SZ)

Kosson, Blackburn, Byrnes, Park, Logan, & Donnelly (2008)


Internal consistency estimates were high, with coefficient alpha equal to .88. Corrected item-to-total correlations ranged from .40 to .74, and a mean interitem correlation of .41 suggests homogeneity for the IM-SZ. Interrater agreement was estimated with an average, one-way random effects ICC, based on 123 cases in which interviewer and observer ratings were available, and was acceptable, r = .69, indicating that the traits measured are relatively robust across raters. Individual item ICCs were somewhat lower; the mean item ICC was .53—Kosson, Blackburn, Byrnes, Park, Logan, & Donnelly, 2008.

Results provide preliminary indications that the measure of SZPD correlates with other

measures in specific ways that suggest preliminary construct validity. Scores on the IM-SZ appear independent of age, education, and SES yet correlated negatively with IQ. Similarly, IM-SZ scores were generally independent of criminal activity yet correlated in predicted ways with ratings on several components of psychopathy—Kosson, Blackburn, Byrnes, Park, Logan, & Donnelly, 2008.
