The association between cigarette smoking and DSM-IV nicotine dependence among first year college students.

AIMS: This study was undertaken to evaluate the association between cigarette smoking behavior and DSM-IV nicotine dependence. DESIGN: Drawing on a sample of first year college students selected for representation across a continuum of smoking behavior, current DSM-IV nicotine dependence criteria were assessed among participants reporting any smoking in the preceding week on a web-based survey protocol. Logistic regression and receiver operator characteristic analyses were used to estimate the overall concordance between smoking and DSM-IV nicotine dependence. FINDINGS: Relationships were supported between both quantity and frequency of smoking in the past week and DSM-IV nicotine dependence showing higher prevalence of dependence at higher levels of use (p<0.05). While the highest prevalence of nicotine dependence was seen among those reporting the most frequent and heavy smoking, a substantial number of participants reporting daily and/or heavy smoking did not meet criteria for nicotine dependence. Conversely, nicotine dependence was seen among a subgroup of participants reporting relatively low levels of non-daily smoking. Diagnostic concordance was found to be moderate for both quantity and frequency and was not improved by combining information from these two indices. CONCLUSIONS: Aside from confirming DSM-IV nicotine dependence at relatively low levels of smoking, these results may be used to inform research aimed at identifying samples of nicotine dependent youth across the range of smoking levels.

Alcohol-related and alcohol-free activity participation and enjoyment among college students: a behavioral theories of choice analysis.

College student alcohol abuse remains a significant public health problem, and there is a need for theory-driven and empirically based models to guide prevention efforts. Behavioral theories of choice assume that the decision to consume alcohol is influenced by the relative value of alcohol versus other available activities. In the present study, a sample of college student drinkers (N=108; 56% female, 44% male) who had previously completed a mandatory alcohol intervention completed a measure of alcohol-related and alcohol-free activity participation and enjoyment. The goals of the study were to examine the influence of drinking quantity and contextual variables on activity enjoyment and to identify enjoyable alcohol-free activities that take place on evenings when students might otherwise be drinking. Overall, students found alcohol-related activities more enjoyable than alcohol-free activities, and drinking quantity was positively related to enjoyment. However, alcohol-free activities such as watching movies, going to the theater or museums, going to bars or parties, hanging out with friends, eating at restaurants, and engaging in creative activity were generally as enjoyable as drinking. Alcohol-free activities that included peers or dates were more enjoyable than solitary activities. Men were less likely to engage in alcohol-free activities that included peers and reported less enjoyment related to alcohol-free activities than did women. Further research is required to identify procedures for increasing participation in alcohol-free activities and to determine whether increased alcohol-free activity participation results in decreased alcohol consumption.

Effects of motivational interviewing for incarcerated adolescents on driving under the influence after release.

Motivational Interviewing (MI) to reduce alcohol and marijuana-related driving events among incarcerated adolescents was evaluated. Adolescents were randomly assigned to receive MI or Relaxation Training. Follow-up assessment showed that, as compared to RT, adolescents who received MI had lower rates of drinking and driving, and being a passenger in a car with someone who had been drinking. Effects were moderated by levels of depression. At low levels of depression, MI evidenced lower rates of these behaviors; at high levels of depression, effects for MI and RT were equivalent. Similar patterns were found for marijuana-related risky driving, but effects were non-significant.

"I'll never drink like that again": characteristics of alcohol-related incidents and predictors of motivation to change in college students.

OBJECTIVE: Alcohol use and its associated behaviors are among the most common reasons for medical treatment and disciplinary infractions among college students. The purpose of this study was to describe the characteristics of students who had recent serious alcohol-related incidents and to identify predictors of motivation to change alcohol use and heavy drinking in particular, with specific attention to gender. METHOD: Students (N = 227; 52% female) who had been mandated to attend a session of alcohol education following alcohol-related medical treatment and/or a disciplinary infraction were assessed on their alcohol use, alcohol problems, characteristics of their alcohol-related incident, reactions to the incident, attributions about the incident, and motivation to change drinking and heavy drinking. Path and regression analyses were used to identify the individual and incident-related characteristics that were related to motivation to change. RESULTS: Perceived aversiveness of the incident was directly and positively related to motivation to change drinking and heavy drinking. Alcohol consumption in the month before the incident and past-year alcohol problems were negatively related to motivation to change heavy drinking, and women were more motivated to change heavy drinking than men. The more students consumed in the incident, the more likely they were to feel responsible for it, and the more responsible they felt about the incident, the greater its aversiveness. CONCLUSIONS: Individual and incident-related characteristics are both directly and indirectly associated with motivation to change following an alcohol-related incident, and therefore have implications for interventions with college drinkers who have experienced an alcohol-related incident.

The Marijuana Ladder: measuring motivation to change marijuana use in incarcerated adolescents.

The purpose of this study was to determine if a modified version of the Contemplation Ladder, a measure of motivation to change marijuana use among incarcerated adolescents (Marijuana Ladder; ML), was related to marijuana use and treatment engagement. Participants (N=122) in this study were all incarcerated at a state juvenile correctional facility in the Northeast. Adolescents were assessed at the beginning of their incarceration, 2 months into their incarceration, and 3 months after their release. There was a significant negative relationship between ML scores and marijuana use and a significant positive relationship between ML scores and treatment engagement. When controlling for prior marijuana use and age, ML scores at baseline significantly added to the prediction of marijuana use and treatment engagement among incarcerated adolescents. Results support the concurrent validity and the predictive validity of the ML. This measure has the potential to provide important information for Juvenile Justice Facilities that might aid in treatment planning and discharge planning for incarcerated adolescents. In addition, researchers may find a quick visual analog measure of motivation to change marijuana use with good psychometric properties useful.

Nicotine and other substance interaction expectancies questionnaire: relationship of expectancies to substance use.

Smoking and substance abuse co-occur at high rates and substance abusers are less likely to quit smoking than are smokers in general. Therefore, more information about the beliefs substance abusers have about the role of smoking in substance use and in recovery would be useful when designing interventions to impact smoking among substance abusing patients. The present study developed a Nicotine and Other Substance Interaction Expectancies Questionnaire (NOSIE) to investigate the expectancies held by substance abusers in treatment about the effects of smoking on substance use, the effects of substance use on smoking, smoking to cope with recovery, and receptivity to smoking cessation during substance abuse treatment. The 29 items were Likert-rated by 160 substance dependent patients in an inner-city residential substance abuse treatment program and participating in a larger study of smoking at this site. Four components were derived and reduced to a 20-item measure with good reliability. No differences by gender or age were found. On average, the patients reported that substance use almost always increases their smoking or urges to smoke but that smoking only increased substance use or urges about half of the time, that they use smoking to cope with urges to use substances about half of the time, and that they generally agreed that smoking cessation or treatment should be tried during substance abuse treatment and would not harm recovery efforts. Three of the scales correlated with smoking dependence while one scale correlated with drug use severity and heavy drinking days. The scale of receptivity to smoking cessation correlated significantly with measures of motivation and barriers and predicted 1-month smoking cessation outcomes. However, scale scores on smoking to cope with recovery did not significantly predict 3-month relapse to substance use. Implications for theory and clinical interventions with substance abusers who smoke were discussed.

Validation of the timeline follow-back in the assessment of adolescent smoking.

The timeline follow-back instrument (TLFB) is a valid and reliable method of quantifying alcohol use patterns. The use of this instrument has been expanded to assess other behaviors, such as drug use, sexual behavior, binge eating, and panic attacks. Some evidence for the validity and reliability of this assessment instrument has emerged in the area of adult smoking. However, to date, there is no published evidence of its reliability and validity in the assessment of adolescent smoking. The purpose of this study is to present early evidence of the utility of the TLFB to collect information on adolescent smoking behavior. Through secondary data analysis of four studies on adolescent smokers, we examined the associations between the TLFB and measures of dependence, smoking history, respiratory symptoms, and saliva cotinine. Moreover, we examined the stability of the TLFB data across two 15-day time periods. Results provide preliminary evidence of the validity and reliability of the TLFB in the assessment of adolescent smoking. In particular, the TLFB instrument offered important data on the heterogeneity of adolescent smoking patterns beyond a global measure of cigarettes per day, and the reduction of digit bias. Implications of these findings for the assessment of adolescent smoking are discussed.

Using behavioral theories of choice to predict drinking outcomes following a brief intervention.

Behavioral theories of choice predict that substance use is partly a function of the relative value of drugs in relation to other available reinforcers. This study evaluated this hypothesis in the context of predicting drinking outcomes following an alcohol abuse intervention. Participants (N = 54, 69% female, 31% male) were college student heavy drinkers who completed a single-session motivational intervention. Students completed a baseline measure of substance-related and substance-free activity participation and enjoyment. Only women showed a significant reduction in drinking at the 6-month follow-up, and the ratio of substance-related to substance-free reinforcement accounted for unique variance in their drinking outcomes. Women who at baseline derived a smaller proportion of their total reinforcement from substance use showed lower levels of follow-up drinking, even after the authors controlled for baseline drinking level. Male and female participants who reduced their drinking showed increased proportional reinforcement from substance-free activities.

Use of the adolescent SASSI in a juvenile correctional setting.

The Substance Abuse Subtle Screening Inventory-Adolescent (SASSI-A) is used in evaluation and treatment planning for incarcerated juveniles. Validity of the SASSI-A in a juvenile correctional facility was examined using archival data. Findings generally support the validity of SASSI-A substance use scales. However, there is concern regarding the potential for ethnic bias in this setting. Cut-scores suggest that the SASSI-A may best be used for detecting problematic alcohol consumption using the Face Valid Alcohol Scale > or = 3. Future studies should more closely investigate whether the three underlying dimensions of the SASSI-A are useful in treatment planning. Results are presented in light of the relatively new SASSI-A2.

Cue reactivity in adolescents: measurement of separate approach and avoidance reactions.

OBJECTIVE: There were two specific goals for the current study: (1) to demonstrate that adolescents display drug-specific cue reactivity to alcohol and cigarette visual cues that varies based on drug-use history and (2) to test the unique contribution of adolescents' avoidance reactions to alcohol and cigarette cues, independent of approach/craving reaction. METHOD: Adolescents (N = 143; age 13-20 years; 58 males) with varied substance-use histories were recruited from school and community sites. Adolescents were presented with a series of alcohol, cigarette, and nondrug comparison visual cues and reported their approach/craving and avoidance reactions. They also completed individual difference measures related to their alcohol and cigarette use and experiences. RESULTS: When adolescents were grouped according to their current alcohol or cigarette use (no use, low use, high use), increased use of alcohol or cigarettes was associated with stronger reactions (increased approach, decreased avoidance) to cues for that substance but not to nondrug control cues. Simultaneous regression analyses demonstrated that after controlling for approach/craving reactions, avoidance cue reactions predicted unique and/or incremental variance in measures of alcohol and cigarette usage, recent change in patterns of use, alcohol expectancies, alcohol restraint and parental alcohol problems. CONCLUSIONS: Adolescents displayed robust alcohol and cigarette cue-specific reactions that varied systematically with their current use of these drugs. Across numerous clinically relevant individual difference variables, predictive power was greatly enhanced through the inclusion of both avoidance and approach reactions.

Brief motivational intervention for adolescent smokers in medical settings.

This study evaluated the efficacy of using a brief motivational intervention to reduce smoking among adolescent patients treated in a hospital outpatient clinic or Emergency Department. Patients aged 14-19 years (N=85) were randomly assigned to receive either one session of motivational interviewing (MI) or standardized brief advice (BA) to quit smoking. The assessment and intervention were conducted in the medical setting proximal to the patient's medical treatment. Patients were proactively screened and recruited, and were not seeking treatment for smoking. Follow-up assessments were conducted at 1, 3, and 6 months post-intervention. Self-report data indicated that 7-day abstinence rates at 6-month follow-up were significantly higher in the MI group than in the BA group, but this difference was not confirmed biochemically. Self-reported smoking rate (average cigarettes per day) was significantly lower at 1, 3, and 6 months follow-up than it was at baseline. Cotinine levels indicated reduced smoking for both groups at 6 months, but not at 1 month. At 3-month follow-up, only those in MI showed cotinine levels that were significantly reduced compared to baseline. Findings offer some support for MI for smoking reduction among non-treatment-seeking adolescents, but overall changes in smoking were small.

Effects of tobacco deprivation on alcohol cue reactivity and drinking among young adults.

Nicotine and alcohol may have common neurobiological mechanisms of reinforcement. Therefore, withholding one substance might result in compensatory increases in self-administration of the other. This laboratory study investigated the effects of brief tobacco deprivation on alcohol cue-elicited urges to drink, corresponding psychophysiological reactions, and alcohol consumption. Young adults (N=78) who were moderate to heavy smokers and drinkers were stratified and randomized to a 2 x 2 design. Participants were either deprived of tobacco for 5 h or not deprived and then exposed to in vivo alcohol or control beverage cues. Subsequently, participants engaged in a taste-rating task as an unobtrusive measure of alcohol consumption. Tobacco deprivation resulted in increased urge to smoke and decreased cardiovascular responses but did not increase alcohol urges or alcohol consumption. Results indicate that brief tobacco deprivation does not result in compensatory increases in alcohol consumption among young moderate to heavy drinkers.

A randomized clinical trial of a brief motivational intervention for alcohol-positive adolescents treated in an emergency department.

We tested whether a brief motivational interview (MI) would reduce alcohol-related consequences and use among adolescents treated in an emergency department (ED) after an alcohol-related event. Patients aged 13 to 17 years (N = 152) with a positive blood alcohol concentration (BAC) by lab test or self-report were recruited in the ED and randomly assigned to receive either MI or standard care (SC). Both conditions resulted in reduced quantity of drinking during the 12-month follow-up, whereas alcohol-related negative consequences were relatively low and stayed low at follow-up. Adolescents who screened positive for problematic alcohol use at baseline reported significantly more improvement on 2 of 3 alcohol use outcomes (average number of drinking days per month and frequency of high-volume drinking) if they received MI compared with SC. We conclude that brief interventions are recommended for adolescents who present to an ED with an alcohol-related event and report preexisting problematic alcohol use.

Brief alcohol interventions with mandated or adjudicated college students.

This article summarizes the proceedings of a symposium presented at the 2003 RSA Meeting in Ft. Lauderdale, Florida, organized and chaired by Nancy Barnett. The purpose of the symposium was to present information and efficacy data about approaches to brief intervention with students who get into trouble on their campuses for alcohol and as a result are required to attend alcohol education or counseling. Presentations were (1) Differences Between Mandated College Students and Their Peers on Alcohol Use and Readiness to Change, by Tracy O'Leary Tevyaw; (2) An Effective Alcohol Prevention Program for Mandated College Students, by Kim Fromme; (3) Two Brief Alcohol Interventions for a Referred College Population, by Kate Carey; and (4) Brief Motivational Intervention With College Students Following Medical Treatment or Discipline for Alcohol, by Nancy Barnett. The data presented in this symposium indicated that students who are evaluated or disciplined for alcohol use are on average heavy drinkers who drink more heavily than their closest peers. Brief intervention approaches described by the speakers included group classroom sessions, individual motivational intervention, individual alcohol education, and computerized alcohol education. Reductions in consumption and problems were noted across the various intervention groups. Brief motivational intervention as a general approach with mandated students shows promise in that it reduced alcohol problems in a group of mandated students who were screened for being at risk (in the Borsari and Carey study) and increased the likelihood that students would attend further counseling (in the Barnett study).

Motivational enhancement and coping skills training for cocaine abusers: effects on substance use outcomes.

AIMS: This clinical trial investigated effects of motivational enhancement treatment (MET) and group coping-skills training (CST) tailored for cocaine dependence. Effects of MET were hypothesized to be greater with CST and for less motivated patients. DESIGN AND INTERVENTIONS: A 2 x 2 design investigated two individual sessions of MET compared to meditation-relaxation (MRT), followed by four group sessions of CST versus drug education (ED), as daily adjuncts to intensive treatment. SETTING: The substance abuse program provided full-day treatment with a learning-theory and 12-Step orientation. PARTICIPANTS: Cocaine-dependent patients were recruited. MEASUREMENTS: Assessment included treatment retention; change in cocaine-related urge, self-efficacy, pros and cons, and motivation; substance use and problems during 12-month follow-up. Findings Of 165 patients, follow-up status is known for 90% (n = 149). Patients in MET with low initial motivation to change reported less cocaine and alcohol relapse and use days and fewer alcohol problems than MET patients with higher initial motivation. MET produced more employment improvement than MRT, with no other significant benefit for MET. Patients with higher motivation had more cocaine use and alcohol problems after MET than MRT. Group CST reduced cocaine and alcohol use during follow-up for women only and reduced alcohol relapse for men and women. CONCLUSIONS: MET is more beneficial for patients with lower initial motivation than for patients with high initial motivation. CST reduced cocaine and alcohol use for women only and reduced alcohol relapses, in contrast to results with lengthier individual CST.

Adolescent alcohol misuse: methodological issues for enhancing treatment research.

AIMS: The objective of this article is to present an overview of the current state of the field of adolescent alcohol treatment research and to discuss several priorities for future research directions. METHOD: The authors identified trends in adolescent alcohol treatment research from multiple sources, including searches of the National Institutes of Health grantee listings, proceedings from annual meetings of the Research Society on Alcoholism and relevant English-language journal articles available in MEDLINE and PSYCHLIT databases over the past decade. RESEARCH RECOMMENDATIONS: This field must build on its major strength, which has been its success in appreciating the unique developmental characteristics of adolescence and meaningfully incorporating them into adolescent alcohol treatment approaches. Priorities for future research include: empirically investigating the potential value of harm reduction approaches for promoting public health and reducing total harm for adolescents; developing efficacious interventions across a wide range of intensities and settings; increasing the reach and relevance of randomized treatment efficacy trials and their products, with a particular focus on enhancing the recruitment and retention of diverse treatment samples; increasing a focus on key individual difference variables such as co-occurring diagnoses, that may serve as the basis for treatment tailoring; and exploration of the potential benefits of transdisciplinary research.

Screening for cannabis use disorders in an adolescent emergency department sample.

Cannabis, more often than alcohol, is the drug mentioned in substance-related reasons for treatment of an adolescent in an emergency department (ED). This study examined the prevalence of DSM-IV cannabis and alcohol diagnoses in an adolescent ED sample, evaluated the performance (i.e. sensitivity and specificity) of DSM-IV cannabis symptoms and other screening items as indicators of cannabis diagnosis status, and examined parent-adolescent agreement on the presence of cannabis and alcohol diagnoses. Adolescents (ages 13-19, n=442) admitted to an ED for a non-substance-related injury were administered the diagnostic interview schedule for children (DISC). Parents (n=272) of adolescents younger than age 18 completed the DISC-parent version to report on their child's drug use. A minority met criteria for a current DSM-IV cannabis or alcohol diagnosis: 7.9% for both alcohol and cannabis, 7.5% for cannabis-only, and 9.0% for alcohol-only. Frequency of cannabis use had the best overall performance in discriminating those with and without a cannabis diagnosis compared with items on perceived risk of cannabis use, peer cannabis use, and alcohol and cigarette use. Parent reports generally underestimated the adolescent's substance use. Questions on level of substance use generally provide an efficient method of screening adolescents for substance-related problems in an ED setting.
