Purpose: The purpose of the current study is to assess the validity of a screening instrument widely used in addictions treatment (the Substance Abuse Subtle Screening Inventory or "SASSI-3" ), when applied to adults with recent brain injuries.
Subjects: 200 persons who had cleared PTA and were receiving TBI rehabilitation; 70 subjects completed the instrument twice to assess test-retest reliability.
Results: Test-retest reliability for most of the subscales was under .75, however many of the items were reliable. New subscales were devised with the reliable items; decision rules were developed and cross-validated.
Conclusions: With some modifications, this instrument will likely have utility in this population; additional research is warranted.
