Differences between methamphetamine users and cocaine users in treatment

To better understand the distinguishing characteristics of methamphetamine users versus cocaine users, we conducted a retrospective chart review of the 345 patients admitted to an outpatient stimulant treatment program during 1995--1997. Analyses revealed an increase in methamphetamine patients over the 3-year period, and that these patients were more likely than cocaine patients to be male, Caucasian, and gay or bisexual. Methamphetamine patients were also more likely to be HIV-positive, engage in behaviors such as using and sharing needles that place them at high risk for HIV transmission, have a psychiatric diagnosis, and be on psychiatric medications. The two populations did not differ in treatment adherence, as measured by clinic attendance, drug-free urines, and successful completion of treatment. These findings suggest that highly specialized substance abuse treatments for methamphetamine patients may not be needed. Resources may be directed toward addressing their medical and psychiatric diagnostic issues by providing ancillary services to stimulant treatment programs.

Testing the causal role of expectancies in smoking motivation and behavior

The causal role of outcome expectancies in smoking motivation and behavior was tested in a laboratory experiment. Two expectancy manipulations-Health Consequences Expectancy Increase (HC) and Mood Management Expectancy Challenge (MM)-were crossed in a 2 x 2 factorial design. One hundred twenty-three heavy smokers were randomly assigned to the conditions and shown videotaped interviews of smokers and exsmokers followed by an interview that personalized the information. Both manipulations produced changes in targeted expectancies on at least one of two expectancy instruments. As predicted, only the HC manipulation produced increases in motivation to quit smoking and a reduction in smoking 3 months later. This study provides initial evidence that smoking expectancies play a causal role in smoking motivation, consistent with previous research with alcohol.

Wise Mind Project: A School-based Environmental Approach for Preventing Weight Gain in Children

Objective: The Wise Mind pilot study compared the efficacy of an environmental approach for prevention of inappropriate weight gain in children with an active control condition that used an environmental approach for modifying expectancies related to the use of alcohol, tobacco, and drugs.

Programmed therapeutic messages as a smoking treatment adjunct: reducing the impact of negative affect.

Maintaining treatment gains remains a challenge to smoking cessation programs. Smokers prone to negative affect are most likely to relapse. In an effort to improve maintenance, a standard cognitive-behavioral treatment was supplemented with the provision of computer-controlled audiotape players containing personalized therapeutic messages. Either the standard treatment alone, or the standard treatment plus 2 months use of the tape player were provided to 41 smokers. No outcome difference was found between the 2 conditions during the 1-year follow-up. (The combined 1-year abstinence rate was 61%, with 34% continuously abstinent.) The frequency with which participants used the device predicted both posttreatment coping skill use and smoking rate. Most notable was an interaction between treatment condition and negative affect. Provision of the devices negated or reversed the usual association between negative affect and poorer outcome.

Smoking expectancies as mediators between dietary restraint and disinhibition and smoking in college women.

Womens beliefs about the appetite and weight control properties of cigarette smoking, dietary restraint and disinhibition, and smoking status were examined. As hypothesized, dietary restraint and disinhibition predicted appetite and weight control expectancies and smoking rate, such that women higher in dietary restraint and disinhibition reported stronger beliefs in the appetite and weight control properties of cigarettes and were more likely to be smoking than those lower in dietary restraint and disinhibition. Consistent with previous research, smoking expectancies for appetite and weight control predicted smoking status and smoking rate. Smoking expectancies for appetite and weight control were found to mediate the relationship between dietary restraint and smoking, and between disinhibition and smoking. This relationship between smoking and dietary constructs should be considered in smoking cessation and dietary interventions with young women.

The role of social anxiety in a brief alcohol intervention for heavy-drinking college students

The Brief Alcohol Screening and Intervention for College Students (BASICS) reduces alcohol use and alcohol-related problems among undergraduates, yet variability in outcomes exists. Identifying individual difference variables related to outcomes could inform efforts to improve treatment protocols. The current study evaluated the role of social anxiety during BASICS. High socially anxious (HSA; n = 26) and low socially anxious (LSA; n = 44) heavy-drinking undergraduates were randomly assigned to BASICS (n = 38) or an assessment-only control (n = 32). HSA patients reported higher baseline alcohol consumption (typical drinks, weekly quantity, and frequency). BASICS significantly decreased weekly alcohol consumption and alcohol-related problems relative to the control group. Social anxiety moderated outcomes such that in the BASICS condition; HSA patients reported heavier typical drinks at posttest, even after controlling for referral status, baseline typical drinks, and trait anxiety. This was not the case in the control group. HSA patients may benefit from social anxiety-specific interventions during BASICS.

A comparison of delay discounting among smokers, substance abusers, and non-dependent controls

Previous studies have shown that smokers and substance-dependent individuals discount rewards that are available after a delay more than individuals without a history of substance dependence. However, it is not clear whether delay discounting is similar among smokers and substance-dependent individuals. Further, the influence of the combination of smoking and other substance dependence on delay discounting remains unknown. The present study compared the performance of four groups of individuals on a delay discounting task. The groups were (a) heavy smokers with comorbid substance dependence, (b) heavy smokers with no history of substance dependence, (c) never smokers with comorbid substance dependence, and (d) never smokers with no history of substance dependence. Analysis revealed that individuals who smoked and/or were dependent on another substance discounted delayed rewards more than individuals with no history of smoking or other substance dependence. No differences in the task performance of heavy smokers and substance-dependent individuals were found. Notably, participants who were dependent on multiple substances did not discount delayed rewards more than those dependent on only one substance. Overall, findings indicate that smoking and other substance dependence are similarly related to delay discounting.

Brief alcohol intervention for college drinkers: How brief is?

OBJECTIVE Brief interventions for college student drinkers have been shown to be effective in reducing the amount of alcohol consumed as well as the number of alcohol-related problems. However, the duration of brief interventions varies substantially across studies. METHOD In the present study 114 undergraduate students who drank alcohol heavily were randomly assigned to a 10-minute brief intervention, a 50-minute brief intervention, or assessment-only control. The content of the active interventions was based on the same concept, and both interventions incorporated motivational interviewing components. Participants were assessed at baseline and 4-week post intervention on quantity of alcohol use, alcohol-related problems, and protective behavioral strategies. RESULTS As hypothesized, there was a significant difference between participants in the 10-minute intervention and control condition regarding their alcohol consumption at 4-week follow up. However, there was no significant difference between the 50-minute intervention and the control condition on alcohol consumption. There were also no significant differences between active intervention conditions, and neither intervention showed advantages for reducing problems or increasing protective behaviors relative to the control condition. CONCLUSIONS Results suggest a very brief intervention can impact short-term alcohol use outcomes, with potentially no advantage of longer interventions for this population.

The Brief Smoking Consequences Questionnaire– Adult (BSCQ-A): Development of a short form of the SCQ-A

A brief form of the Smoking Consequences Questionnaire-Adult (SCQ-A) was developed as an economical alternative to the 55-item SCQ-A in assessing smoking outcome expectancies in adult, heavy smokers. A total of 25 items (two to three items per each of the 10 SCQ-A scales) were administered to current smokers and ex-smokers. Confirmatory factor analysis was used to determine whether the brief form was better accounted for by a 4- or 10-factor model. Several variants of 9- and 8-factor models also were compared. The 10-factor model, representing the 10 subscales of the full-length SCQ-A, fit the data more adequately than the other models. The Brief SCQ-A (BSCQ-A) scales demonstrated good internal consistency (mean coefficient alpha = .79) and convergent validity. The BSCQ-A also showed promising validity in distinguishing among current smokers and ex-smokers. In a separate sample of smokers, strong and positive associations were present between corresponding pairs of the SCQ-A and BSCQ-A subscales.

Effects of Brief Mindfulness Instructions on Reactions to Body Image Stimuli Among Female Smokers: An Experimental Study

INTRODUCTION Recent research has shown that body image stimuli increase negative affect and smoking urges among female smokers. Mindfulness (paying attention to present-moment experience with an attitude of nonjudgmental acceptance) may be a useful technique to minimize the influence of body dissatisfaction on negative affect, smoking urges, and smoking behavior. METHODS This study investigated whether mindfulness influences how female college smokers respond to a body image challenge. The study used a 2 × 2 factorial design with body image challenge (trying on a bathing suit vs. looking at a purse) crossed with instructions (mindfulness vs. silence). Female smokers (n = 64; M (age) = 20.03 [± 1.77], 87.5% Caucasian) were randomly assigned to one of four conditions: Purse + Silence (n = 16), Body Image + Silence (n = 15), Purse + Mindfulness (n = 15), and Body Image + Mindfulness (n = 18).
