Toxic (aka Destructive) Leadership Scale

There has been a lot of interest in the measurement of Toxic Leadership. Andrew Schmidt did his initial work on his scale in 2008. Andrew created two versions of his scale. This is the original version (developed in his 2008 MA thesis):

Schmidt (2008) Toxic Leadership Scale

 All items rated on a 6-point Likert scale response format, with answers ranging between 1 = “Strongly Disagree” to 6 = “Strongly Agree.”

All items begin with the phrase “My current supervisor…” but this could be changed to direct respondents to rate other leaders (more senior leaders, past supervisors, etc.), depending on the theory of the researchers.

Self-Promotion: alpha = 0.91

  1. Drastically changes his/her demeanor when his/her supervisor is present
  2. Denies responsibility for mistakes made in his/her unit
  3. Will only offer assistance to people who can help him/her get ahead
  4. Accepts credit for successes that do not belong to him/her
  5. Acts only in the best interest of his/her next promotion

 Abusive Supervision:  alpha = 0.93

  1. Ridicules subordinates
  2. Holds subordinates responsible for things outside their job descriptions
  3. Is not considerate about subordinates’ commitments outside of work
  4. Speaks poorly about subordinates to other people in the workplace
  5. Publicly belittles subordinates
  6. Reminds subordinates of their past mistakes and failures
  7. Tells subordinates they are incompetent

Unpredictability: alpha = 0.92

  1. Has explosive outbursts
  2. Allows his/her current mood to define the climate of the workplace
  3. Expresses anger at subordinates for unknown reasons
  4. Allows his/her mood to affect his/her vocal tone and volume
  5. Varies in his/her degree of approachability
  6. Causes subordinates to try to “read” his/her mood
  7. Affects the emotions of subordinates when impassioned

Narcissism: alpha = 0.88

  1. Has a sense of personal entitlement
  2. Assumes that he/she is destined to enter the highest ranks of my organization
  3. Thinks that he/she is more capable than others
  4. Believes that he/she is an extraordinary person
  5. Thrives on compliments and personal accolades

 Authoritarian Leadership:  alpha = 0.89

  1. Controls how subordinates complete their tasks
  2. Invades the privacy of subordinates
  3. Does not permit subordinates to approach goals in new ways
  4. Will ignore ideas that are contrary to his/her own
  5. Is inflexible when it comes to organizational policies, even in special circumstances
  6. Determines all decisions in the unit whether they are important or not
