Workplace Arrogance Scale (WARS)

 


Scale name: Workplace Arrogance Scale (WARS)

Scale overview: The 26-item Workplace Arrogance Scale measures arrogance in the workplace based on self-report using a 5-point rating scale.

Authors: Russell E. Johnson of Michigan State University and others—see the article reference for the author list.

Response Type: A 5-point Likert type rating scale from 1 = strongly disagree to 5 = strongly agree

Sample items:

1. Believes that s/he knows better than everyone else in any given situation

2. Makes decisions that impact others without listening to their input

Reliability: The 26-item WARS alpha was .93 in Johnson et al., 2010.

Validity Factor analysis indicated a one-factor scale. Arrogance was positively correlated with dominance, anger, superiority, entitlement, and vanity.

Arrogance was negatively correlated with humility, agreeableness, conscientiousness, and self-sufficiency. Arrogance was not related to authority.

Availability: See Table A1 on page 427 of the 2010 article for the 26 items.

Narcissistic Personality Inventory-13


The Narcissistic Personality Inventory - 13 (NPI-13) was developed by Gentile et al. (2013). It is a shortened version of the 40-item NPI.

The authors describe trait narcissism as a trait on a continuum with features of "a grandiose sense of self, feelings of entitlement, and a dominant and antagonistic interpersonal style (p. 1120)."


Scale and subscales

The NPI-13 has three subscales (alpha values in parentheses):

Leadership/authority (.66)

Grandiose Exhibitionism (.65)

Entitlement/ exploitativeness (.51)

Total Scale alpha = .73.

Psychometric Properties

In general, the three NPI scales were significantly positively correlated with grandiose scales from the PNI and NGS, psychological entitlement, and both self-report and interview-based symptom of NPD. All three were also positively related to self-esteem scores," (Gentile et al., 2013, p. 1124).

The authors also found positive correlations between the NPI scales and DSM-IV-TR personality disorders of paranoid, antisocial, and histrionic.

See Gentile et al. (2013) below for details of the two studies and how the NPI-13 and other versions performed.

Sample items

I like having authority over other people.

I have a strong will to power.

Dark Triad Scale (Dirty Dozen)


The toxic triad is commonly known as the Dark Triad


The triad consists of three sets of personality traits 
representing features of 

Narcissistic, 
Psychopathic, and 
Machiavellian 

personality clusters. 









The Dirty Dozen Scale

Psychological Scientists Peter Jonason and Gregory Webster developed a scale known as the Dirty Dozen (2010), which uses 12-items to identify key features of this “Dark” or Toxic Triad.

Here’s the 12 items

1.      I tend to manipulate others to get my way.
2.      I tend to lack remorse.
3.      I tend to want others to admire me.
4.      I tend to be unconcerned with the morality of my actions.
5.      I have used deceit or lied to get my way.
6.      I tend to be callous or insensitive.
7.      I have used flattery to get my way.
8.      I tend to seek prestige or status.
9.      I tend to be cynical.
10.  I tend to exploit others toward my own end.
11.  I tend to expect special favors from others.
12.  I want others to pay attention to me.

Each item is rated on a 7-point Likert-type scale based how much it applies to a person. Here’s the subscales:

Narcissism = 3, 8, 11, 12
Psychopathy = 2, 4, 6, 9
Machiavellianism = 1, 5, 7, 10

As you can see, scores could range from 12 to 84. Webster & Jonason (2013) examined the scale in samples totaling 1,014 college students. The second sample used the 7-point rating scale, which resulted in an overall item mean of 2.92 and SD of 1.07.

Overall alpha was .87. See Table 3 of their article for more details. Note that this is a general population college sample thus we would expect higher scores in clinical samples.

For a more recent meta-analytic review of various measures of the Dark Triad, see Muris et al., 2017 (reference below).
