Measure Description: 

The TABS is the revised version of the Traumatic Stress Institute (TSI) Belief Scale and was designed for use with individuals who
have experienced traumatic events. However, it has also been used by researchers to assess the effects of vicarious traumatization.

It assesses beliefs/cognitive schema in five areas that may be affected by traumatic experiences: 1) Safety, 2) Trust, 3) Esteem, 4) Intimacy, and 5) Control.

The measure yields a total TABS score and scores on ten subscales: 1) Self-Safety, 2) Other-Safety, 3) Self Trust, 4) Other- Trust, 5) Self-Esteem, 6) Other-Esteem, 7) Self-Intimacy, 8) Other-Intimacy, 9) Self-Control, and 10) Other-Control. The TABS can "help identify possible trauma history, psychological themes in trauma materials, document progress in treatment, and help direct clinicians focus their treatment" (Pearlman, 2003).

Although the measure was originally normed with adults aged 17 and older, it was designed to be suitable for adolescents, and adolescent norms are now available.

Describe Alternative Forms: 

(Pearlman, 2003, p. 29)
The TABS is a revision of the Traumatic Stress Institute Beliefs Scale, Revision L.

The primary difference is that many items were worded to make them easier to read in order to develop a form that could eventually be used with "youngsters."

In addition 4 new items were added and some items with low item-scale correlations were replaced with items that were more related to the given subscale.

Demographics
Notes on Psychometric Norms: 

The measure has been normed with adults aged 17 and older and adolescents aged 9-18. Adolescent norms are derived from a sample of
1,242 students, aged 9-18. The normative group is described under “Population Used to Develop Measure” and in the manual, appendix table, p.
41.

Clinical Cutoffs: 
No
If Yes, Specify Cutoffs: 
While no formal cutoffs are specified, T-scores >60T are considered to be high scores indicative of relative disruption in a given area.

References for Content Validity: 

Pearlman (2003, p. 29):
100 items were collected from statements made by trauma survivor clients that were
reflective of the six areas originally identified by Constructivist Self-Development Theory
(Safety, Trust, Independence, Power, Intimacy, and Self-Esteem).

Expert reviewers then assigned items to one of the six areas, and items were eliminated if
the assigned category was not the same for all experts.

This process left a 76-item scale, called the McPearl Belief Scale. Through subsequent
research, the measure was refined. New items were generated from client statements to
improve reliability of some subscales, and items that reduced internal consistency were
eliminated.

The concept of power was reconceptualized as control. Independence was conceived of as
counterdependence and items from that subscale were subsumed into the Trust and Control
subscales.

earlier version of this scale (Traumatic Stress Institute Beliefs Scale).

2. Pearlman (2003, p. 36-38): Factor analysis with a nonclinical college sample:
while not all items loaded on the scales as would be expected, the analysis
provides some support for the theoretical model on which the TABS is based.

3. Varra, Pearlman, Allen, & Brock (manuscript in preparation) have conducted
a factor analysis of the TABS. They found three factors (Self, Safety, and Other),
providing an alternative way of interpreting scores. (See manual, pp. 36, 39. This
research was presented at the annual meeting of the International Society of
Traumatic Stress Studies.)

4. Outpatients with a trauma history have higher TABS score than do
outpatients in general, and those with a child abuse history have even higher
TABS scores.

5. Therapists’ scores on the earlier version of the TABS were moderately
correlated with scores on the Maslach Burnout Inventory, Third Edition,
suggesting that they measure related but different constructs (McLean, Wade, &
Encel, 2003). Correlations with the Trauma Symptom Inventory (TSI) provide
support for convergent and discriminant validity of subscales.

Overall Psychometric Limitations: 

1. Much of the psychometric research was conducted using the earlier version of the
measure: Revision L of the Traumatic Stress Institute Belief Scale. Although both versions
correlate highly, new items were added, and more psychometric research is needed with the
newest version of the TABS.

2. The psychometrics have not been fully explored for culturally or clinically diverse
populations. The author conducted analyses looking at ethnic/racial differences on mean
scale scores. African Americans scored significantly higher on Other-Safety, Other-Trust,
and Other-Esteem. On average, Asian Americans scored significantly higher than the
expected 50T. Latinos scored significantly lower on average on Other-Intimacy.

While these results were hypothesized to result from sampling artifacts due to the small
sample size, given that the sample included 113 African Americans, 59 Asian Americans,
and 51 Latinos, it may also be reflective of real cultural differences.

These findings suggest, as the author notes, that caution is needed when interpreting the
results for different cultural groups.

3. Numerous studies have been conducted using the TABS to measure the effects of
vicarious traumatization with clinicians and have found evidence of validity of the measure
with this population. Clinicians working with greater number of trauma victims have higher
TABS ratings (Schauben & Frazier, 1995, as cited in Pearlman, 2003).

Clinicians’ TABS scores (using the TSI Belief Scale -- the original version of the TABS) are
related to their own trauma history, with those with trauma histories showing greater
disruption on TABS scales, and less experienced therapists with trauma histories showing
the most difficulty (Pearlman & Mac Ian, 1995).

Population Information

Population Used For Measure Development: 

The measure was developed using two samples:
Test development data are drawn from 810 clinical respondents, with an average age of 35.5 (SD=12.1).

Normative data were gathered on a heterogeneous sample of 1,743 individuals from nonclinical research groups aged 17-78. Young, Caucasian women are overrepresented, and older individuals, men, and minorities are underrepresented. The ethnic/racial composition was 49% Caucasian, 38% unspecified race/ethnicity, 6% African American, 3% Latino, 3% Asian, and 1% Native American (Pearlman, 2003, p. 30).

Pros & Cons/References

Pros: 

1. Measure is theoretically based and designed to assess key domains that are hypothesized to be affected by trauma exposure.

2. One article suggests that measure may be useful in assessing treatment effects.

3. Measure focuses on identifying disruptions in cognitions related to relational difficulties. Given the link between relational difficulties and trauma exposure, a measure of this type may be very useful for clinical and research purposes.

4. Measure may be a useful way for measuring one aspect of vicarious traumatization in clinicians.

Cons: 

1. Difference in mean scores for different ethnic groups suggest caution is needed when interpreting results for those from different cultural backgrounds. While this is a limitation, it should be noted that most measures have not been examined in depth for differences of this type and may also be subject to the same limitation.

2. While there is evidence for the validity of using the measure to assess vicarious traumatization with clinicians, there is no evidence of its reliability with this population.

3. The scale appears to have been more widely used to measure vicarious traumatization than direct traumatization. More research is needed looking at its utility in assessing individuals who have directly experienced trauma.
