The TSEE is a brief measure of participants’ prior experiences with 12-step groups. Individuals are asked to indicate whether they have ever attended 12-step groups (AA, NA, CA, and CMA) or other substance-related selfhelp groups (Secular Organizations for Sobriety [SOS], Rational Recovery [RR]). If they have, they are asked to estimate the number of meetings they have attended in total and over the past 3 months, and to rate how helpful they feel that the meetings have been. They are also asked how likely they are to get involved in a 12-step group during this treatment episode and how helpful they anticipate such involvement will be.

The Treatment Effect Assessment (TEA) (Ling, 2009) is a 4-item self-administered assessment used to assess patient progress in treatment and recovery. It  uses a Likert scale (1-10) to document the patient's sense of what is important within four domains established by prior research: substance use, health (physical or emotional), lifestyle (e.g. housing/living situation, family, employment, relationships), and community (e.g. obeying laws, responsible member of society).

Greater congruence of participant’s expectations of treatment and beliefs regarding the causes and nature of substance use with those of the treatment they receive may result in improved outcome over participants whose treatment expectations contrast with study treatment received (Hall et al., 1991). The Treatment Attitudes and Expectation form, a self-report of treatment attitudes, adapted from the NIMH TDCRP (Elkin et al., 1985), has been modified for use with drug dependent individuals.
