The check-up: in-person, computerized, and telephone adaptations of motivational enhancement treatment to elicit voluntary participation by the contemplator.

Countless barriers come between people who are struggling with substance abuse and those charged with providing substance abuse treatment. The check-up, a form of motivational enhancement therapy, is a harm reduction intervention that offers a manner of supporting individuals by lowering specific barriers to reaching those who are untreated. The check-up was originally developed to reach problem drinkers who were neither seeking treatment nor self-initiating change. The intervention, marketed as an opportunity to take stock of one's experiences, involves an assessment and personalized feedback delivered with a counseling style termed motivational interviewing. Check-ups can be offered in care settings to individuals who, as a result of screening, manifest risk factors for specific disorders such as alcoholism. They can also be free-standing and publicized widely to the general public. This paper will discuss illustrations of in-person, computerized, in-school, and telephone applications of the free-standing type of check-up with reference to alcohol consumers, adult and adolescent marijuana smokers, and gay/bisexual males at risk for sexual transmission of HIV. The paper's major focus is to highlight how unique features of each application have the potential of reducing barriers to reaching specific at-risk populations. Also considered are key policy issues such as how check-up services can be funded, which venues are appropriate for the delivery of check-up interventions, pertinent competency criteria in evaluating staff who deliver this intervention, how marketing can be designed to reach contemplators in untreated at-risk populations, and how a check-up's success ought to be defined.

Internet-based intervention for mental health and substance use problems in disaster-affected populations: a pilot feasibility study.

Early interventions that reduce the societal burden of mental health problems in the aftermath of disasters and mass violence have the potential to be enormously valuable. Internet-based interventions can be delivered widely, efficiently, and at low cost and as such are of particular interest. We describe the development and feasibility analysis of an Internet-delivered intervention designed to address mental health and substance-related reactions in disaster-affected populations. Participants (n = 285) were recruited from a cohort of New York City-area residents that had been followed longitudinally in epidemiological research initiated 6 months after the terrorist attacks of September 11, 2001. The intervention consisted of 7 modules: posttraumatic stress/panic, depression, generalized anxiety, alcohol use, marijuana use, drug use, and cigarette use. Feasibility data were promising and suggest the need for further evaluation.

Motivational enhancement therapy for adolescent marijuana users: a preliminary randomized controlled trial.

This study's aims were (a) to investigate the feasibility of a school-based motivational enhancement therapy (MET) intervention in voluntarily attracting adolescents who smoke marijuana regularly but who are not seeking formal treatment and (b) to evaluate the efficacy of the intervention in reducing marijuana use. Ninety-seven adolescents who had used marijuana at least 9 times in the past month were randomly assigned to either an immediate 2-session MET intervention or to a 3-month delay condition. Two thirds of the sample characterized themselves as in the precontemplation or contemplation stages of change regarding marijuana use. Participants' marijuana use and associated negative consequences were assessed at baseline and at a 3-month follow-up. Analyses revealed that both groups significantly reduced marijuana use at the 3-month follow-up ( p = .001); however, no between-group differences were observed. Despite the absence of a clear effect of MET, this study demonstrated that adolescents could be attracted to participate in a voluntary marijuana intervention that holds promise for reducing problematic levels of marijuana use.

Abstinence and moderate use goals in the treatment of marijuana dependence.

AIMS: The purpose of this study was to examine the influence of personal goals (abstinence or moderation) on treatment outcomes for marijuana use. Hypotheses regarding self-efficacy for goal attainment were tested. DESIGN: Adult marijuana users seeking treatment were assigned randomly to three treatment conditions: (1) cognitive-behavioral relapse prevention support group; (2) individualized brief motivational enhancement; and (3) delayed treatment control group. Follow-up assessments were conducted at 4, 7, 13 and 16 months. SETTING: University research offices. PARTICIPANTS: Participants were 291 adult marijuana users. Measurements Marijuana use, personal treatment goals and self-efficacy for achieving one's goal were assessed across the 16-month follow-up. FINDINGS: Greater marijuana related problems and dependence symptoms were associated with an initial goal of abstinence. Participants were more likely to achieve outcomes consistent with their personal goals. Participants with abstinence goals reported greater self-efficacy for goal achievement than those with moderation goals after participating in the abstinence oriented treatment; self-efficacy for goal success predicted goal achievement for both moderate use and abstinence goals. CONCLUSIONS: Marijuana users approaching an abstinence-oriented treatment varied in the extent to which they were actively seeking abstinence as the outcome. Differences in goals were predictable from severity of problems related to use. Goal preference and self-efficacy for achieving goals predicted outcomes. Future research should incorporate personal goals into treatment and assess their effects on outcomes.

Information-Motivation-Behavioral Skills (IMB) Model: testing direct and mediated treatment effects on condom use among women in low-income housing.

BACKGROUND: The Information-Motivation-Behavioral Skills (IMB) model of HIV preventive behavior (1-4) specifies that treatment effects on behavior occur largely as the result of treatment effects on behavioral skills, which follow from effects on information and motivation. PURPOSE: The objective was to determine whether the variables specified by the IMB model of HIV preventive behavior (1-4) accounted for the relation between an IMB-based treatment and resulting HIV preventive behavior (condom use). METHOD: Women (n = 557) living in 18 low-income housing developments in 5 geographically dispersed cities were recruited to participate in an HIV-prevention study. Women (within housing developments) were randomly assigned to receive an IMB-based, HIV risk-avoidance intervention or a comparison intervention. Baseline and posttreatment (16 months after baseline) data were collected on condom use information, motivation (social norms, attitudes, intentions, and perceived risk), enactment of behavioral skills (condom negotiation and procurement), and rates of condom use in the past 2 months. RESULTS: The IMB intervention led to a 12% to 16% increase in condom use rates over the course, whereas the comparison intervention led to 2% decrease. In addition, the IMB treatment led to greater increases in condom use information, in the intentions and social norms components of motivation and the condom procurement and condom conversations components of behavioral skills. The IMB model provided an acceptable fit to the data (root mean square error of approximation < .05) and accounted for 50% of the variance in posttreatment condom use among the sample. Treatment effects on condom use were almost entirely mediated by the IMB variables; specifically, motivation and enactment of behavioral skills mediated the intervention's impact on condom use. CONCLUSIONS: These results provide supporting evidence as to how theoretical variables operate to effect change within a theory-based intervention and provide evidence as to the applicability of a prevailing theory of HIV risk behavior among low-income minority women.

Marketing the 'Sex Check': evaluating recruitment strategies for a telephone-based HIV prevention project for gay and bisexual men.

Designing effective marketing and recruitment strategies for HIV prevention research requires attention to cultural relevance, logistical barriers, and perceived psychosocial barriers to accessing services. McGuire's communication/persuasion matrix (1985) guided our evaluation, with particular attention to success of each marketing "channel" (i.e., strategy) vis-à-vis the number of all callers, eligible callers, and enrolled callers, as well as reaching so-called "hard-to-serve" individuals. Nearly all channels offered success in reaching specific subgroups. Latinos responded favorably to posters, bisexuals responded favorably to paid media in an alternative (non-gay) publication, and precontemplators responded to referrals by family and friends. Although multiple recruitment strategies were used, three were crucial to the success of the project: (a) recruiters' presence in gay venues, (b) referrals by family and friends (snowball technique), and (c) paid advertisements in alternative (non-gay) local newspapers. Resource allocation and costs are also presented for each channel.

Correlates of nonparticipation in an HIV prevention program for MSM.

Providing HIV prevention services to high-risk individuals remains challenging. We assessed factors associated with nonparticipation among high-risk, sexually active MSM found eligible to participate in a brief, telephone-delivered HIV prevention trial designed to evaluate the efficacy of motivational enhancement therapy (the Sex Check). Two levels of nonparticipation are evaluated: eligible participants who did versus those who did not complete their baseline/enrollment interview, and enrolled participants who did versus those who did not attend any of their counseling sessions. Nonenrollers were younger, less educated, more closeted, and were more likely to report sex with an injection drug using partner. Enrolled participants who did not engage in their counseling session(s) were less educated, reported greater use of alcohol and drugs during sex and use of injection drugs. Innovative methods to reduce barriers to engaging high-risk, sexually active MSM in risk reduction counseling are needed.

Outcomes of a randomized, controlled community-level HIV prevention intervention for adolescents in low-income housing developments.

OBJECTIVES: Youth are increasingly at risk for contracting HIV infection, and community-level interventions are needed to reduce behavioral risk. DESIGN: A randomized, controlled, multi-site community-level intervention trial was undertaken with adolescents living in 15 low-income housing developments in five US cities. METHODS: Baseline (n = 1172), short-term follow-up (n = 865), and long-term follow-up (n = 763) risk assessments were conducted among adolescents, ages 12-17, in all 15 housing developments. The developments were randomly assigned in equal numbers to each of three conditions: experimental community-level intervention (five developments); "state-of-the-science" skills training workshops (five developments); and, education-only delayed control intervention (five developments). RESULTS: At long-term follow-up, adolescents living in the housing developments receiving the community-level intervention were more likely to delay onset of first intercourse (85%) than those in the control developments (76%), while those in the workshop developments (78%) did not differ from control condition adolescents. Adolescents in both the community-level intervention (77%) and workshop (76%) developments were more likely to use a condom at last intercourse than those in control (62%) developments. CONCLUSIONS: Community-level interventions that include skills training and engage adolescents in neighborhood-based HIV prevention activities can produce and maintain reductions in sexual risk behavior, including delaying sexual debut and increasing condom use.

Psychological distress and marijuana use before and after treatment: testing cognitive-behavioral matching hypotheses.

The purpose of this study was to examine the relationship between psychological distress, self-efficacy, and marijuana use using data from a randomized controlled trial of treatments for marijuana dependence [J. Consult. Clin. Psychol. 68 (2000) 898-908]. Adult marijuana users seeking treatment (N=291) were randomly assigned to three treatment conditions: (1) cognitive-behavioral relapse prevention support group (RPSG), (2) individualized assessment and advice group (IAI), and (3) delayed treatment control group (DTC). As predicted, psychologically distressed individuals had lower self-efficacy for avoiding marijuana use in psychologically distressing (PD) situations as opposed to nonpsychologically distressing (NPD) situations. However, all participants tended to have lower self-efficacy for NPD situations than PD situations. Efficacy increased and marijuana use decreased following treatment but the RPSG treatment did not have greater benefit for psychologically distressed participants.

HIV risk behavior among ethnically diverse adolescents living in low-income housing developments.

PURPOSE: To describe patterns and predictors of HIV risk behaviors among ethnically diverse, low-income adolescents. METHODS: Computer-assisted surveys were administered to 1172 adolescents between the ages of 12 and 17 years living in 15 low-income housing developments in three urban areas in the United States to characterize and identify predictors of HIV risk behavior. Data were analyzed using multinomial logistic regression to identify variables predictive of "no risk," "lower risk," and "higher risk" group classification. RESULTS: Most adolescents were not yet sexually active; nonetheless, a subset of youth reported high rates of HIV risk-related behaviors. HIV risk was highest among adolescents who were older, had weaker intentions to reduce risk, stronger beliefs that their sexual partners did not favor risk-reduction, lower risk-reduction behavioral skills, higher risk-reduction outcome expectation, and higher rates of substance use. CONCLUSIONS: HIV prevention efforts are needed that are tailored to ethnically diverse communities of adolescents, including those in early adolescence and those at highest risk.

The Marijuana Check-up: reaching users who are ambivalent about change.

AIMS: A brief intervention called the Marijuana Check-up (MCU) was designed to attract adult marijuana users who were experiencing adverse consequences, but who were ambivalent about change and would be unlikely to seek treatment. Our objective was to determine whether the MCU would reach the target population. DESIGN: Comparisons were made between those who enrolled in the MCU versus those who were screened but failed to follow through with enrollment on demographic, drug use and stage of change variables. Comparisons were also made between participants in the MCU and participants in a concurrently offered treatment project that targeted marijuana users who wanted to quit. SETTING: The study took place at the University of Washington in Seattle. PARTICIPANTS: Participants were adult marijuana users who telephoned and expressed interest in the MCU (n = 587). MEASUREMENT: Study variables included stage of change, frequency and duration of drug use, DSM-IV cannabis dependence and abuse diagnoses and negative consequences of marijuana use assessed via interviews and questionnaires. FINDINGS: Callers to the MCU were near-daily marijuana users, two-thirds of whom were in the pre-contemplation or contemplation stage of change. Participants who enrolled in the MCU reported fewer problems related to marijuana use and less readiness to make changes compared to those enrolled in the treatment study, despite similar levels of drug use. CONCLUSIONS: The MCU attracted and enrolled near-daily users of marijuana who experienced negative consequences but were ambivalent about making changes. The MCU potentially has a role in the continuum of care for substance abuse problems.

Cognitive functioning of long-term heavy cannabis users seeking treatment.

CONTEXT: Cognitive impairments are associated with long-term cannabis use, but the parameters of use that contribute to impairments and the nature and endurance of cognitive dysfunction remain uncertain. OBJECTIVE: To examine the effects of duration of cannabis use on specific areas of cognitive functioning among users seeking treatment for cannabis dependence. DESIGN, SETTING, AND PARTICIPANTS: Multisite retrospective cross-sectional neuropsychological study conducted in the United States (Seattle, Wash; Farmington, Conn; and Miami, Fla) between 1997 and 2000 among 102 near-daily cannabis users (51 long-term users: mean, 23.9 years of use; 51 shorter-term users: mean, 10.2 years of use) compared with 33 nonuser controls. MAIN OUTCOME MEASURES: Measures from 9 standard neuropsychological tests that assessed attention, memory, and executive functioning, and were administered prior to entry to a treatment program and following a median 17-hour abstinence. RESULTS: Long-term cannabis users performed significantly less well than shorter-term users and controls on tests of memory and attention. On the Rey Auditory Verbal Learning Test, long-term users recalled significantly fewer words than either shorter-term users (P =.001) or controls (P =.005); there was no difference between shorter-term users and controls. Long-term users showed impaired learning (P =.007), retention (P =.003), and retrieval (P =.002) compared with controls. Both user groups performed poorly on a time estimation task (P<.001 vs controls). Performance measures often correlated significantly with the duration of cannabis use, being worse with increasing years of use, but were unrelated to withdrawal symptoms and persisted after controlling for recent cannabis use and other drug use. CONCLUSIONS: These results confirm that long-term heavy cannabis users show impairments in memory and attention that endure beyond the period of intoxication and worsen with increasing years of regular cannabis use.

Tailoring cannabis dependence treatment for a diverse population.

Accumulating evidence suggests that psychosocial treatment for cannabis dependence is effective. Earlier investigations were well designed and sought to evaluate efficacy of manual-guided therapies with particular attention to protecting the independent variable. The Marijuana Treatment Project (MTP) represents an effort to build upon previous knowledge about cannabis dependence treatment through an evaluation of an integrative therapy, which was meant to allow for greater therapist latitude in its delivery, and to be more responsive to a potentially more diverse population of clients. The treatment intervention developed for delivery in the Marijuana Treatment Project (MTP) reflects an effort to find a true compromise between the needs of the scientific community to have clearly specified and measurable treatments, and the realities of the treatment community, which demand flexibility, appreciation of the multi-determined nature of most problems, and individualized approaches. This paper will describe the clinical interventions used with the MTP participants, the theoretical rationale guiding their design and practical aspects related to implementation and treatment response.
