Purpose: Measure self-destructive behavior patterns and screen for suicide intent
Age: 16 through to 70 yrs
Admin: Individual or group
Time:15-20 minutes for the FAST; 5 minutes for the FASI
The FAST is an 84-item self-report measure that is derived from 20 years of clinical research into self-attacking attitudes, or introjects, that restrict or impair an individual's psychological development.
The FAST was designed to capture different symptoms that are characteristic of suicidal individuals including hopelessness, depression, anxiety, and suicide ideation. In addition to providing a means of assessing these characteristics, the FAST is a measure of a broad range of self-destructive behavior patterns. The FAST is organized into 11 levels of self-destructive thoughts (e.g., Level 1—Self-Depreciation, Level 11—Suicide Injunctions).
With the FAST, the clinician can identify the level at which the client is experiencing the highest frequency (intensity) of self-destructive thoughts. Utilizing this information, clinicians can direct their interventions toward the area(s) in which clients are experiencing psychological pain, thereby potentially averting the acting out of the corresponding self-destructive behavior. This aspect of the scale is particularly important in the case of suicide, for which immediate, appropriate intervention may be lifesaving. Clinicians also are able to identify and address less extreme types of self-destructive thoughts before they lead to or precipitate a suicidal crisis.
The FASI is a brief suicide screener that clinicians can administer when they wish to assess only suicide intent. This subset of the FAST consists of 27 items from Levels 7-11 of the FAST. These 27 items, which compose the Suicide Intent Composite of the FAST, are the most predictive of suicide risk.
Reliability and Validity
The measure incorporates a unique approach. Instead of asking a client to report beliefs or symptoms he or she is experiencing, the client is asked to endorse how frequently he or she is experiencing self-critical/self-depreciating thoughts in the form of an internal dialogue or voice (i.e., negative thoughts directed toward oneself). Endorsing items in this format allows the client to reflect on and report the contents of his/her negative thought process or voice. When items are presented in this form, they bring to light elements of a self-destructive process that have been partially or completely unconscious.
For both the FAST and FASI, the scale raw scores are summed and normative scores are provided in the form of T scores and percentiles. The FAST contains five composite scores: Self-Defeating, Addictions, Self-Annihilating, Suicide Attempt, and Total Score.
The clinician can use the FAST to stimulate discussion in therapy sessions regarding significant issues in a client's life that neither the client nor the clinician might have been aware of prior to the administration of the measure. Clients have reported that reading and endorsing the items made them aware of self-limiting and/or self-destructive thoughts that had not previously been part of their conscious awareness. Responses to the measure also alert the clinician to patterns of self-destructive behavior that need to be investigated.
Internal consistency reliability coefficients for the composite scores that include multiple levels range from .95 to .97. The internal consistency estimates for the levels range from .76 to .91, with a median alpha of .84. The test-retest correlations range from .63 to .94, with an average of .82.
The coefficients for all composites constructed from level scores (i.e., Self-Defeating Composite, Self-Annihilating Composite, Total Score) range from .95 to .97.
A number of procedures were implemented to establish the validity of the FAST: (a) expert reviews, (b) factor analytic studies, (c) correlations with other measures of self-destructive thoughts or behaviors, (d) studies of specificity and sensitivity of the test to discriminate a variety of clinical groups, and (e) studies of special clinical groups.
The original 220-item pool for the FAST consisted of verbatim statements made by clients during Voice Therapy groups. The most suicidal voices or thoughts consisted of self-statements reported by individuals who had made serious suicide attempts and who were actively suicidal. The remainder consisted of negative thoughts reported by clients with a variety of patterns of self-destructive behavior, including substance abuse.
The FAST Total Score had its highest correlations with the Suicide Ideation subscale of the Suicide Probability Scale (SPS; 76), the Beck Depression Inventory® (BDI®), and the Beck Suicide Inventory (BSI). These findings support the contention that the Total Score is a measure of suicide ideation and depression, or self-destructive thoughts at the highest end of the continuum.
