Dark Triad Dirty Dozen (DTDD)
The Dark Triad Dirty Dozen (DTDD) is a valid and brief 12-item personality inventory developed to capture the possible presence of three comorbid socially maladaptive traits - the dark triad:
- Narcissism (items 4, 5, 6, 7): pride self-centeredness, inability to empathize with others,
- Machiavellianism (3, 8, 9, 10): manipulation, cynicism, selfishness,
- Psychopathy (1, 2, 11, 12): recklessness, callousness, impulsiveness.
It consists of short statements expressing tendencies characteristic of each component of the dark triad, with the respondent recording the degree of agreement with these statements.
Length of completion
The entire inventory takes approximately 3 minutes to complete.
Individualized feedback to the respondent
After the DTDD has been assessed, the experimenter will learn whether the subject has any Dark Triad traits.
Keywords
Dark Triad Dirty Dozen, DTDD, dark triad, dark triad, narcissism, Machiavellianism, psychopathy
Scoring and interpretation
It is possible to calculate a total score for each subscale separately or a total score for the whole inventory. A higher score indicates a higher feature rate.
Response Scale
Respondents answer the DTDD items on a 7-point Likert scale: “strongly disagree” (1) to “strongly agree” (7).
