Toxic Leadership Scale
Also known as: Destructive Leadership Scale
The Toxic Leadership Scale (TLS) is a 16-item instrument measuring destructive leadership behaviors including abusive supervision, narcissism, and authoritarian control. Developed by Einarsen, Aasland, and Skogstad in 2007, the TLS identifies harmful leadership behaviors that undermine organizational effectiveness and employee well-being.
Key highlights
- Identifies destructive leader behaviors often overlooked in positive leadership measures that assess only what leaders do well
- Grounded in organizational stress theory and empirically linked to negative outcomes including burnout, turnover, and psychological distress
- Multi-source assessment capability (self, subordinate, peer, observer) enables triangulation and verification of concerning behaviors
- Actionable measure enabling specific behavioral feedback and coaching

When to use it
The TLS is valuable in leadership effectiveness evaluation, human resources investigation, executive coaching needs assessment, and organizational health monitoring. Use it to identify toxic leaders, investigate culture concerns, determine coaching interventions, assess leadership fit, and monitor leadership behavior change following feedback or intervention.
Strengths & limitations
- Identifies destructive leader behaviors often overlooked in positive leadership measures that assess only what leaders do well
- Grounded in organizational stress theory and empirically linked to negative outcomes including burnout, turnover, and psychological distress
- Multi-source assessment capability (self, subordinate, peer, observer) enables triangulation and verification of concerning behaviors
- Actionable measure enabling specific behavioral feedback and coaching
- Self-report validity questionable; toxic leaders often lack insight into their impact, significantly underestimating scores versus subordinate ratings
- Subject to supervisor retaliation concerns when subordinates provide honest feedback; anonymous administration essential but not always feasible
- Does not assess competence or organizational contribution; toxic leaders may demonstrate high technical ability despite damaging behaviors
- Single point-in-time measurement captures behavior snapshot only; destructive behavior may vary situationally or over time

Frequently asked
Can toxic leaders change their behavior through coaching?
Limited evidence supports behavior change without intense intervention. Some toxic behaviors reflect personality traits (narcissism, authoritarianism) resistant to coaching. Others may respond to feedback if leaders have self-awareness and genuine motivation to change. Coaching success depends on leader accountability and consequence structure from organizational leadership.
Should toxic leaders be removed from organizations immediately?
Organizations balance competing interests: immediate removal protects employee welfare and prevents further damage; measured approach with feedback, coaching, and monitoring provides development opportunity while protecting subordinates. Decision depends on toxicity severity, leader amenability to change, and organizational risk tolerance for staying the course.
How common is toxic leadership in organizations?
Research suggests 10–15% of leaders demonstrate significantly toxic patterns affecting employee well-being. However, toxic behaviors exist on a continuum; many leaders exhibit occasional toxic behaviors without reaching pathological levels. Regular TLS assessment helps organizations identify toxic patterns before they become entrenched.
