Brown et al developed the two-item conjoint screening (TICS) based on a 5-item conjoint screening questions. While the two-item score is the best for screening for alcohol and/or subtance abuse, the other items provide additional insights. The authors are from the University of Wisconsin at Madison.
A conjoint screening question inquires simultaneously and "in aggregate" the person's experience with alcohol and/or drugs.
Time Interval: during the last year
Questions - Have you:
(1) felt that your usage was more than intended (meant to used)? (loss of control)
(2) felt a need to cut-down on usage? (recognized a problem)
These two items were used in the two-item screen (TICS).
There were 3 additional questions that were evaluated:
(3) not remembered things that happened (blackout)
(4) used alcohol or drugs to dealt with feelings, stress or frustrations? (feelings, coping, self-medication)
(5) done anything that you wish hadn't happened? (regret)
