Description

The Triarchic Psychopathy Measure (TriPM) is a 58-item, self-report questionnaire designed to measure psychopathy in terms of three distinct phenotypic constructs (Patrick, Fowles, & Krueger, 2009): boldness, defined as the nexus of high dominance, low anxiousness, and venturesomeness; meanness, reflecting tendencies toward callousness, cruelty, predatory aggression, and excitement seeking; and disinhibition, reflecting tendencies toward impulsiveness, irresponsibility, oppositionality, and anger/hostility. Each construct is measured by a separate subscale. Subscale scores are summed to yield a total psychopathy score.

Specific Instructions

In the "Protocol" text below, a bracketed [F] appears following some items to indicate that the item is reverse-scored. Instances of [F] should be deleted from the protocol for purposes of administration. A manual for a description of the psychopathy elements and instructions can be found in the Psychiatric Working Group supplemental information: [silink[120000">Triarchic Manual

Scoring

Step 1: Coding Responses

Code responses for all other items as follows: True = 3; Somewhat true = 2; Somewhat false = 1; False = 0.

Step 2: Computing Scale Scores and Total Scores

Boldness subscale (19 items)-Sum coded responses for the following items:

1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 32, 35, 38, 41, 44, 47, 50, 54, 57

Meanness subscale (19 items)-Sum coded responses for the following items:

2, 6, 8, 11, 14, 17, 20, 23, 26, 29, 33, 36, 39, 40, 42, 45, 48, 52, 55

Disinhibition subscale (20 items)-Sum coded responses for the following items:

3, 5, 9, 12, 15, 18, 21, 24, 27, 30, 31, 34, 37, 43, 46, 49, 51, 53, 56, 58

Selection Rationale

The Triarchic Psychopathy Measure (TriPM) was selected because it is a validated, brief, self-report instrument consisting of readable items with strong psychometric properties that index distinct phenotypic facets of psychopathy with low burden for investigators and respondents. In particular, TRiPM was preferred over other nonproprietary psychopathy protocols because it specifically assesses the boldness facet of psychopathy.

Psychiatric
Measure Name

Psychopathy-related Constructs

Release Date

May 12, 2010

Definition

This is a questionnaire to assess psychopathy-related constructs (psychopathic personality). Individuals high in psychopathy-related constructs are socially facile but emotionally insensitive, egocentric, lacking in affection or concern for others, deceitful and manipulative, forceful and aggressive, venturesome, impulsive, and irresponsible (APA, 2000; Hare, 2003; Lilienfeld & Andrews, 1996; Patrick, Fowles, & Krueger, 2009).

Purpose

This measure can be used to screen individuals from the general population for the presence of psychopathy-related constructs. These characteristically entails antisocial or rule-breaking behavior, co-occurs frequently with substance abuse, and is common in incarcerated populations (APA, 2000; Hare, 2003).

Keywords

Psychiatric, antisocial personality disorder, sociopathy, personality disorder, externalizing
