This supplemental instrument is a measure of immediate recall, in which the participant is presented with a list of 15 unrelated words via audio recording and is asked to recall as many as he/she can. This process is repeated, and the score is equal to the total number of words recalled across all trials.

The RFQ is composed of 20 self-report items, and measures intrinsic and extrinsic motivation for quitting smoking. It consists of two intrinsic motivation subscales, self-control (e.g., "To show myself I can quit if I really want to") and health concerns (e.g., "Because I'm concerned that smoking will shorten my life"), and two extrinsic motivation subscales, immediate reinforcement (e.g., "To save money that I spend on cigarettes") and social pressure (e.g., "Because someone has given me an ultimatum to quit"). The RFQ is both valid and reliable and may be useful from a research perspective as well as a clinical one, especially in randomized trials when comparing one study population to another.

This assessment includes a four-item scale to assess participants’ readiness to use condoms consistently.

This assessment includes one question to assess participants’ readiness for HIV testing

The QIDS-SR-16 is a 16-item depression scale, yielding scores from 0-27, which covers the symptom domains of major depressive disorder, for the time frame of the past week: mood; concentration; suicidal ideation; anhedonia; loss of energy; insomnia; appetite change; psychomotor agitation/retardation; as well as self-esteem.

Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF; Endicott et al,1993). The Q-LES-Q-SF evaluates general activities that are assessed in the longer form of the Q- LES-Q. Each item uses a 5-point scale ranging from 1 (very poor) to 5 (very good). A total score is derived from 14 items with a maximum score of 70 and with higher scores indicating greater life satisfaction and enjoyment. Participants rate their satisfaction with the following domains of activity: physical health, feelings, work, household duties, school/course work, leisure time activities, and social relations. Test-retest reliability for the Q-LES-Q-SF has been shown to be .86 (Rapaport et al, 2005) and internal consistency (Cronbach’s alpha) has been shown to range from .86 to .90 (Rapaport et al, 2005; Wyrwich et al, 2009).

The PRISM (formerly known as the SCID-A/D) is a semi-structured clinician-administered interview that measures the major Axis I DSM-IV diagnoses (current and past) of alcohol, drug, and psychiatric disorders. The PRISM was designed to provide clear guidelines for differentiating between the expected effects of intoxication and withdrawal, substance-induced disorders, and primary disorders. It is also useful for studying the effects of comorbidity on the longitudinal course of alcoholism or alcoholism treatment outcome. The PRISM can also be used to differentiate subjects in order to study treatment-matching strategies when psychopathology is one of the matching variables. The PRISM also covers two Axis II disorders, Borderline Personality Disorder and Antisocial Personality Disorder. This instrument was designed to maximize reliability and validity in heavy drinkers and users of drugs. Although primarily designed as a research instrument, the PRISM provides systematic coverage of alcohol- and drug-related experiences and symptoms that may be useful in identifying areas of focus for treatment. Additionally, the unusually high reliability of the depression diagnoses in individuals with heavy drinking may provide a better basis for treatment decisions than less consistent methods for assessing major depression and dysthymia.

This is a self-report inventory that assesses the frequency and severity of PTSD symptoms corresponding to DSM-IV diagnostic criteria.

The Pittsburgh Sleep Quality Index (PSQI) (Buysse et al., 1989) is a brief, validated instrument that measures sleep quality. It is a nineteen item self assessment of sleep quality and disturbances over a one-month time interval, and generates seven component scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.
