This scale is a 40-item measure that was used in the NIDA Cocaine/Psychotherapy Study to evaluate mediators of outcome in drug counseling. Items are based on the 12-step approach to recovery ("I know that recovery from addiction is a lifelong process," "When I experience craving, I go to a 12- step meeting," "I haven't gotten around to getting a sponsor," "I rely on my higher power to help me stay clean." The internal consistency reliability (Cronbach's alpha) of the total of the 40-items was found to be 0.82 using baseline data from the main clinical trial in the Cocaine/Psychotherapy Study.

This assessment includes physical, sexual and emotional abuse items. In each domain the participant is asked to report: lifetime occurrence (YES/NO); lifetime frequency (4-point scale from once to regularly); need for medical treatment (YES/NO); use of medical treatment (YES/NO); length of time since last occurrence; occurrence with main partner (YES/NO); occurrence with other than main partner (YES/NO); and past 3 month frequency (on a 1 – 6 scale of daily to no occurrence). Participants are also asked age of first sexual abuse and description of perpetrator (e.g. different family members, strangers, etc.). It has been shown that abuse is positively associated with sexual risk behavior.
