Effects of a brief intervention for reducing violence and alcohol misuse among adolescents: a randomized controlled trial.

CONTEXT Emergency department (ED) visits present an opportunity to deliver brief interventions to reduce violence and alcohol misuse among urban adolescents at risk of future injury. OBJECTIVE To determine the efficacy of brief interventions addressing violence and alcohol use among adolescents presenting to an urban ED. DESIGN, SETTING, AND PARTICIPANTS Between September 2006 and September 2009, 3338 patients aged 14 to 18 years presenting to a level I ED in Flint, Michigan, between 12 pm and 11 pm 7 days a week completed a computerized survey (43.5% male; 55.9% African American). Adolescents reporting past-year alcohol use and aggression were enrolled in a randomized controlled trial (SafERteens). INTERVENTION All patients underwent a computerized baseline assessment and were randomized to a control group that received a brochure (n = 235) or a 35-minute brief intervention delivered by either a computer (n = 237) or therapist (n = 254) in the ED, with follow-up assessments at 3 and 6 months. Combining motivational interviewing with skills training, the brief intervention for violence and alcohol included review of goals, tailored feedback, decisional balance exercise, role plays, and referrals. MAIN OUTCOME MEASURES Self-report measures included peer aggression and violence, violence consequences, alcohol use, binge drinking, and alcohol consequences. RESULTS About 25% (n = 829) of screened patients had positive results for both alcohol and violence; 726 were randomized. Compared with controls, participants in the therapist intervention showed self-reported reductions in the occurrence of peer aggression (therapist, -34.3%; control, -16.4%; relative risk [RR], 0.74; 95% confidence interval [CI], 0.61-0.90), experience of peer violence (therapist, -10.4%; control, +4.7%; RR, 0.70; 95% CI, 0.52-0.95), and violence consequences (therapist, -30.4%; control, -13.0%; RR, 0.76; 95% CI, 0.64-0.90) at 3 months. At 6 months, participants in the therapist intervention showed self-reported reductions in alcohol consequences (therapist, -32.2%; control, -17.7%; odds ratio, 0.56; 95% CI, 0.34-0.91) compared with controls; participants in the computer intervention also showed self-reported reductions in alcohol consequences (computer, -29.1%; control, -17.7%; odds ratio, 0.57; 95% CI, 0.34-0.95). CONCLUSION Among adolescents identified in the ED with self-reported alcohol use and aggression, a brief intervention resulted in a decrease in the prevalence of self-reported aggression and alcohol consequences.

Minimizing participant attrition in panel studies through the use of effective retention and tracking strategies: Review and recommendations☆

Abstract Participant attrition poses a significant threat to the internal and external validity of panel studies, in part because participants who successfully complete all follow-up measurements often differ in significant ways from those respondents lost to attrition. The only certain safeguard against potential biases resulting from attrition is to ensure high interview completion rates during follow-up. Unfortunately, information about reducing preventable attrition is not discussed in most research reports and a comprehensive review paper has not yet been published. The purpose of the present paper is to provide a brief overview of how attrition can threaten the validity of panel studies and to discuss eight promising methods of minimizing attrition through the use of effective retention and tracking strategies. Attempts to reduce attrition are not always met with complete success, therefore, a brief discussion of statistical techniques to assess and correct for potential attrition biases is provided. Finally, methods of calculating attrition rates are suggested along with recommendations for future research.

Individual and social/environmental predictors of alcohol and drug use 2 years following substance abuse treatment.

The purpose of this study was to identify individual and social/environmental predictors of alcohol and drug use 2 years following substance abuse treatment. Participants (n=180) self-administered questionnaires within their first month of substance abuse treatment and completed a 2-year follow-up interview. Individual factors (coping, self-efficacy, resource needs, and expectations for sober fun), social/environmental factors (craving, exposure, negative social influences, and involvement in substance-using leisure activities), and background characteristics measured during treatment were used to predict alcohol and drug use during a 2-year follow-up using manifest variable regression analysis. Results suggest that poorer self-efficacy, greater involvement in substance-using leisure activities, being single, and less income predicted alcohol use directly, whereas greater resource needs and involvement in substance-using leisure activities, being of minority status, and being single predicted drug use directly. Income, gender, problem severity, marital status, and race also predicted alcohol and drug use indirectly. Findings highlight differential predictors of posttreatment substance use that may be useful in developing alternative approaches to prevent relapse.

Brief motivational interviewing intervention for peer violence and alcohol use in teens: one-year follow-up.

BACKGROUND AND OBJECTIVES: Emergency department (ED) visits present an opportunity to deliver brief interventions (BIs) to reduce violence and alcohol misuse among urban adolescents at risk for future injury. Previous analyses demonstrated that a BI resulted in reductions in violence and alcohol consequences up to 6 months. This article describes findings examining the efficacy of BIs on peer violence and alcohol misuse at 12 months. METHODS: Patients (14–18 years of age) at an ED reporting past year alcohol use and aggression were enrolled in the randomized control trial, which included computerized assessment, random assignment to control group or BI delivered by a computer or therapist assisted by a computer. The main outcome measures (at baseline and 12 months) included violence (peer aggression, peer victimization, violence-related consequences) and alcohol (alcohol misuse, binge drinking, alcohol-related consequences). RESULTS: A total of 3338 adolescents were screened (88% participation). Of those, 726 screened positive for violence and alcohol use and were randomly selected; 84% completed 12-month follow-up. In comparison with the control group, the therapist assisted by a computer group showed significant reductions in peer aggression (P < .01) and peer victimization (P < .05) at 12 months. BI and control groups did not differ on alcohol-related variables at 12 months. CONCLUSIONS: Evaluation of the SafERteens intervention 1 year after an ED visit provides support for the efficacy of computer-assisted therapist brief intervention for reducing peer violence.

Before and after the trauma bay: the prevention of violent injury among youth.

Despite a decline in the incidence of homicide in recent years, the United States retains the highest youth homicide rate among the 26 wealthiest nations. Homicide is the second leading cause of death overall and the leading cause of death for male blacks aged 15 to 24 years. High rates of health care recidivism for violent injury, along with increasing research that demonstrates the effectiveness of violence prevention strategies in other arenas, dictate that physicians recognize violence as a complex preventable health problem and implement violence prevention activities into current practice rather than relegating violence prevention to the criminal justice arena. The emergency department (ED) and trauma center settings in many ways are uniquely positioned for this role. Exposure to firearm violence doubles the probability that a youth will commit violence within 2 years, and research shows that retaliatory injury risk among violent youth victims is 88 times higher than among those who were never exposed to violence. This article reviews the potential role of the ED in the prevention of youth violence, as well as the growing number of ED- and hospital-based violence prevention programs already in place.

Rates and Correlates of Violent Behaviors Among Adolescents Treated in an Urban Emergency Department

PURPOSE Violence is a leading cause of death for adolescents in inner-city settings. This article describes violent behaviors in relation to other risk behaviors (e.g., substance use) among adolescents screened in an urban emergency department (ED). METHODS Patients aged 14-18 years were approached to self-administer a computerized survey assessing violent behaviors (i.e., physical aggression), substance use (cigarettes, alcohol, marijuana), and weapon carriage. RESULTS A total of 1128 adolescents (83.8% participation rate; 45.9% male; 58.0% African-American) were surveyed. In the past year, 75.3% of adolescents reported peer violence, 27.6% reported dating violence, and 23.5% reported carrying a weapon. In the past year, 28.0% drank alcohol, 14.4% binge drank, 5.7% reported alcohol-related fighting, and 36.9% smoked marijuana. Logistic regression analyses predicting violent behaviors were significant. Teens reporting peer violence were more likely to be younger, African-American, on public assistance, carry a weapon, binge drink, and smoke marijuana. Teens reporting dating violence were more likely to be female, African-American, carry a weapon, binge drink, screen positive for alcohol problems, and smoke marijuana. Teens reporting alcohol-related fighting were more likely to carry a weapon, binge drink, screen positive for alcohol problems, and smoke marijuana. CONCLUSIONS Adolescents presenting to an urban ED have elevated rates of violent behaviors. Substance use (i.e., binge drinking and smoking marijuana) is an important risk factor for violent behaviors among urban adolescents. Universal screening and intervention protocols to address multiple risk behaviors, including violent behaviors and substance use, may be useful to prevent injury among adolescents presenting to the urban ED.

The Relationship Between Alcohol Problems and Health Functioning of Older Adults in Primary Care Settings

OBJECTIVE: The purpose of this study was to determine the relationship between alcohol use and health functioning in a sample of older adults screened in primary care settings.

Older adult treatment outcome following elder-specific inpatient alcoholism treatment

This study examined multidimensional 6-month outcomes of elder-specific inpatient alcoholism treatment for 90 participants over the age of 55. At baseline, physical health functioning was similar to that reported by seriously medically ill inpatients in other studies while psychosocial functioning was worse, and nearly one third of the sample had comorbid psychiatric disorders. Based on 6-month outcomes, participants were classified into the following groups: Abstainers, Non-Binge Drinkers, and Binge Drinkers. The groups did not differ on any baseline measures (demographics, drinking history, alcohol symptoms and age of onset, comorbidity, or length of treatment). General health improved between baseline and follow-up for all groups. Psychological distress decreased for Abstainers and Non-Binge Drinkers, but did not change for Binge Drinkers. Results suggest that a large percentage of older adults who receive elder-specific treatment attain positive outcomes across a range of outcome measures.

Partner aggression among men and women in substance use disorder treatment: correlates of psychological and physical aggression and injury.

This study examined intimate partner aggression in a sample of 489 participants enrolled in substance use disorder treatment, and expands on prior research by including measures of various forms of aggression, a mixed gender sample (76% men, 24% women), and measurement of several potential risk domains. Aggression measures included both participant-partner and partner-to-participant psychological aggression, physical aggression and injury. Analyses focused on the role of distal and proximal risk factors, including demographics, history of childhood physical and sexual abuse, and family history of problems with alcohol, drugs and depression, as well as recent substance use and symptoms of depression. Overall rates of participant-partner psychological aggression (77%), physical aggression (54%) and injuring partners (33%) were high, as were rates of partner-to-participant psychological aggression (73%), physical aggression (51%), and injury (33%). Several distal (family history variables, physical abuse) and proximal factors (binge drinking, several different drugs, depressive symptoms) were bivariately related to most of the aggression measures. However, according to multivariate analyses predicting aggression and injury measures, binge drinking and cocaine use were the drugs significantly associated with most measures, depression symptoms also were related to most aggression and injury measures, and a history of reported childhood physical abuse was related to all frequency of aggression and injury measures among those reporting such behaviors. Overall, the high rates of aggression among both men and women observed in this study further illustrate the need for interventions targeting substance use and aggression, and for further research regarding the inter-relationships among substance, aggression and depressive symptoms.

Characteristics of adults seeking medical marijuana certification

BACKGROUND Very little is known about medical marijuana users. The present study provides descriptive information on adults seeking medical marijuana and compares individuals seeking medical marijuana for the first time with those renewing their medical marijuana card on measures of substance use, pain and functioning. METHODS Research staff approached patients (n=348) in the waiting area of a medical marijuana certification clinic. Chi-square and Wilcoxon signed rank tests were used to compare participants who reported that they were seeking medical marijuana for the first time (n=195) and those who were seeking to renew their access to medical marijuana (n=153). RESULTS Returning medical marijuana patients reported a higher prevalence of lifetime cocaine, amphetamine, inhalant and hallucinogen use than first time patients. Rates of recent alcohol misuse and drug use were relatively similar between first time patients and returning patients with the exception of nonmedical use of prescription sedatives and marijuana use. Nonmedical prescription sedative use was more common among first time visitors compared to those seeking renewal (p<0.05). The frequency of recent marijuana use was higher in returning patients than first time patients (p<0.0001). Compared to first time patients, returning patients reported somewhat lower current pain level and slightly higher mental health and physical functioning. CONCLUSIONS Study results indicate that differences exist between first time and returning medical marijuana patients. Longitudinal data are needed to characterize trajectories of substance use and functioning in these two groups.
