Literature facing

Clinical assessment

(age range of 18 through adulthood)

The PAI provides informations for clinical diagnosis, treatment planning and screening for psychopathology.

The 11 scales may be divided into three broad classes of disorders:

  • neurotic spectrum

  • psychotic spectrum

  • behavior disorder

  • impulse control problems

Clinical

Substance abuse

The Alcohol Problems (ALC) and Drug Problems (DRG) scale scores reflect the degree to which respondents engage in substance use and the adverse consequences that result.

Moderately elevated scores (e. g., 70T) are suggestive of abuse, whereas markedly elevated scores (e. g., 85T) suggest dependence.

Because the items for ALC and DRG inquire directly about substance use, the scales are susceptible to denial.

Fals-Stewart (1996) found that the 57T cut score on PIM (Positive Impression) had a sensitivity of 88% and a specificity of 80% in distinguishing questionable responding in substance abusers.

Substance abuse

Psychiatric assessment

Psychiatric disorders

  • Psychotic - spectrum symptomatology

- Paranoia (PAR): correlates with diagnostic assessment of paranoia made via structured clinical interview.

- Mania (MAN): measures affective, cognitive, and behavioral symptoms of mania and hypomania.

- Schizophrenia (SCZ): measure of general impairment

  • Neurotic-spectrum symptomatology:

- Anxiety (ANX): Measures concerns with phenomenology and observable signs of anxiety.

- Anxiety Related Disorder (ARD): associated with nightmares & terrors

- Depression (DEP): correlates with BDI, HRS and MMPI.

Personality disorders

The Borderline Features (BOR) scale is composed of 4 subscales designed to measure Affective Instability, Identity Problems, Negative Relationships, and Self-Harm .

Studies suggest that a T score > 70 accurately classified 81.8% of the BPD patients and 77.3% of the female students (Bell-Pringle, Pate, and Brown, 1997)

The Antisocial Features (ANT) scale has three subscales designed for assessing antisocial behaviors (ANT-A: Antisocial Behaviors) and

antisocial traits including callousness, self-centeredness, and lack of empathy in interactions with others (ANT-E: Egocentricity); and also willingness to take risks and a desire for novelty (ANT-S: Stimulus Seeking)

Personality disorders

Forensic assessment

  • Competence (to stand trial or to represent themselves)
  • Determining individual's mental status
  • Criminal responsibility
  • Risk assessment

critical factor in decision making and treatment planning

Risk of violence

Malingering

Malingering

Malingering "strongly suspected" with > 2

indices:

PAI MAL Cut scores

  • Screen for feigning: MAL scores > 2 or > 3

  • Likely feigning: MAL scores > 4 (about 1% genuine misclassified)

*Feigners misclassified of 33% (>2) and 14% (>3)

PAI NIM Cut scores

  • Rule-out feigning: NIM score < 73T (4.5% of feigners misclassified)

  • Screen for feigning : Elevations on NIM: 77T to 109T; about 20% genuine misclassified

  • Likely feigning: Extreme elevations on NIM: > 110T (about 2% genuine misclassified)
  • 344 items
  • 22 non-overlapping full scales
