Participant liking of OROS-MPH/placebo will be assessed with the Drug Rating Questionnaire. This questionnaire is a derivative of the ARCI Benzedrine scales [Martin et al., 1971] to evaluate likeability and potential abuse based on the subjective response of the participant with ADHD. The Drug Rating Questionnaire is a visual analog scale that includes additional questions that assist in disentangling the therapeutic effects of the medication from the euphoria scales - an important confound as recently articulated by Kollins [2003] in children with ADHD. There are no currently psychometrically validated scales available for such purposes in ADHD adults. The Drug Rating Questionnaire has been used successfully in clinical trials of adults with ADHD.

"The Drug Abuse Screening Test (DAST) was designed to provide a brief instrument for clinical and non-clinical screening to detect drug abuse or dependence disorders. It is most useful in settings in which seeking treatment for drug use problems is not the patient's stated goal. The DAST provides a quantitative index of the severity of problems related to drug abuse other than alcohol. DAST scores are highly diagnostic with respect to a DSM diagnosis of psychoactive drug dependence. The DAST is available in both 20-item and 10-item formats; an Adolescent version is also available. In addition, the DAST provides a general measure of lifetime problem severity that can be used to guide further inquiry into drug-related problems and to help determine treatment intensity. It takes about 5 minutes to administer the DAST-20 and 2 minutes to score the DAST-10. NOTE re: history and alternate names: The original measure had 28 items and was adapted from the MAST. The 20-item version of the DAST was found to have psychometric properties comparable with the 28-item version, and is now commonly referred to as the DAST, or DAST-20. The DAST is also known as the Drug Use Questionnaire (DUQ) (DUQ-20 and DUQ-10). The DAST-10 was selected in 2012 by a group of researchers from the National Drug Abuse Treatment Clinical Trials Network (CTN) to serve as the recommended assessment tool for use in general medical settings.

The DISC-C has undergone several adaptations and now features a DSM-IV version. There are separate forms of the interview for the parent and the child. As part of a larger study focusing on several diagnoses, Fisher and colleagues (1993) found the DISC-C to be highly sensitive in correctly identifying youth who had received a hospital diagnosis of any substance use disorder (n=8). Both interview forms had a sensitivity of 75%. For the one parent-child disagreement case, the parent indicated that they did not know any details about their child's substance use.

This survey was developed to collect information clinic-wide in order to assess interest in smoking cessation.

This 23-item questionnaire (originally adapted from the Processes of Change questionnaire, Prochaska et al. 1998) assesses change processes and skills taught in coping skills treatment, such as problem solving and dealing with urges to use substances of abuse. Participants will rate on a 4-point scale their frequency of using each strategy to help avoid substance use. Total coping is measured by taking the mean across all 23 items. The CSS yields 4 subscales: active-behavioral, active-cognitive, avoidant-behavioral, and avoidant-cognitive.

The Conventional Activities of Friends Scale will be used to measure prosocial activities of friends. This scale includes 8 questions concerning the number of friends that engaged in prosocial activities. These behaviors range from obeying school rules to participating in religious activities. High scores indicate that most friends engage in these conventional behaviors, and the lowest scores reflect the complete absence of any friends involved in these prosocial and traditional activities. Scale scores are summed for each subject, thereby reflecting the overall degree of exposure to peers engaged in these conventional behaviors. This scale will be used as an indicator of prosocial activities in testing Hypothesis 2d.

Condom use skill is measured, separately, for male and female condoms using checklists of necessary actions. It is measured by (dichotomous) observer ratings of the presence or absence of basic skills for use of each. For each, a total count of number of skills observed is obtained. The following skills for putting a male condom on a penis model are observed: Expiration date on package is checked; package is opened carefully; condom checked for damage; condom rolled correctly downward; condom rolled to base of penis; air removed from condom; space left at tip of condom; lubricant added to condom or penis; withdrew condom and moved away from mode; took care to avoid spilling; and tied off condom and disposed of in trash. The following skills for putting a female condom in a vagina model are observed: expiration date checked; the package is opened carefully; condom checked for damage; condom unrolled and two rings separated; condom rubbed gently to evenly spread lubricant; inner ring squeezed between finger; inner ring pushed into vaginal canal while squeezed; inner ring placed against cervix; outer ring covers outside of vagina; after used condom is twisted and removed taking care not spill contents; and condom disposed of in trash can.

The Condom Use Self-Efficacy Scale (CUSES) can be used to assess an individual's perception of his or her ability to use condoms. It has four subscales: Mechanics (putting a condom on self or other), Partner Disapproval (use of condom with a partner's approval), Assertive (ability to persuade a partner to use a condom), and Intoxicants (ability to use condoms while under the influence).

The Condom Barriers Scale is an 29-item instrument designed to measure men and women's perceived barriers to condom use for prevention of HIV and other sexually transmitted diseases. Items are rated on a five-point Likert scale (from "strongly agree" to "strongly disagree") and include statements like: "Most of the time, neither of us has a condom available," "Condoms rub and cause irritation," "Condoms cost too much," or "If I suggested my partner use a condom he/she might think I am putting him/her down or insulting him/her."
