Firestone Assessment of Self-Destructive Thoughts (FAST)
The Firestone Assessment of Self-Destructive Thoughts (FAST), published by The Glendon Association, is based on the clinical theory of Robert Firestone. This approach, which integrates cognitive and psychodynamic concepts, assesses the levels of self-destructive thoughts a person is experiencing, along a specific Continuum of Negative Thought Patterns. Clinicians can learn valuable information about clients' levels of functioning along this continuum. The continuum begins with self-critical thoughts of everyday life (Level 1), progresses to self-abusive thoughts and vicious self-accusations (Level 5), then on to those thoughts leading to addictive behavior or substance abuse (Level 6), and finally to injunctions to carry out a suicidal plan. (Level 11).

Firestone Assessment of Suicidal Intent (FASI)
Most individuals at risk for committing suicide experience self-defeating and self-destructive thought processes that can be conceptualized as an internal dialogue or "voice." The FASI is based on voice therapy theory, which is a comprehensive approach to psychopathology and corresponding model of mental health. It is a short efficient subscale derived from the larger instrument, the Firestone Assessment of Self-Destructive Thoughts (FAST). Whereas the FAST assesses a broad range of self-destructive thoughts, the FASI more specifically determines an individual's suicidal risk.
