Does Fibular Displacement Predict Tibial Malrotation in Simulated Tibia-Fibula Fractures.

INTRODUCTION: Tibial malrotation can occur with medullary nailing of diaphyseal tibial fractures. Fibular alignment has been proposed as a surrogate for axial plane reduction intraoperatively. The purpose of this study was to determine whether fibular alignment is a reliable marker of accurate tibial rotation. METHODS: Deidentified CT scans of 50 patients with normal tibial anatomy were selected. Using ImageJ software, we simulated osteotomies at three sites (proximal third, mid-diaphysis, and distal third). We overlaid adjacent CT slices and rotated them around the central axis of the tibia in 5° increments of external rotation (ER) and internal rotation (IR). At each increment, measurements of fibular overlap (%) were obtained from anteroposterior (AP) and lateral views. To simulate fixation of the fibula, we repeated rotation around the axis of the fibula with and without a simulated medullary implant in the tibia. RESULTS: A total of 50 patients were included. The mean age was 62 years, average BMI was 25.8, and 28 of 50 patients (56%) were male. Earliest loss of fibular contact occurred at 24° ER and 22° IR at the proximal site. Contact was lost at 26° ER and 28° IR on the AP view and 42° ER and 29° IR on the lateral view. The mean fibular contact at each 5° increment was similar for ER and IR. Fibular contact was reduced to 50% at 10 to 15° of rotation in ER and IR at all sites. Tibial canal contact was lost at 24° in both ER and IR around the fibula. With a virtual medullary implant, the mean maximal rotation was 6°. DISCUSSION: Surgeons should be aware that 20° or more of malrotation is likely present when fibular contact is lost during medullary nailing of the tibia. Greater than 50% loss of contact should raise suspicion for malrotation. A fixed fibula and medullary tibial implant theoretically preclude significant tibial malrotation.

Recruitment and Retention of Homeless Youth in a Substance Use and HIV-risk Reduction Program.

Conducting intervention studies with homeless populations can be difficult, particularly in terms of retaining participants across multiple sessions and locating them for subsequent follow-up assessments. Homeless youth are even more challenging to engage due to substance use, mental health problems, wariness of authority figures, and frequent relocations. This article describes methods used to successfully recruit a sample of 200 homeless youth from two drop-in centers in Los Angeles, engage them in a four-session substance use and sexual risk reduction program (79% of youth attended multiple sessions), and retain 91% of the full sample at a three-month follow-up assessment. Our experience indicates that utilizing structured project materials and having a small dedicated staff are essential to recruitment and retention efforts for intervention studies with homeless youth. Using these and other nontraditional methods are likely necessary to engage this at-risk yet hard-to-reach population.

Using marijuana, drinking alcohol or a combination of both: the association of marijuana, alcohol and sexual risk behaviour among adolescents.

Background Although the association between alcohol use and sexual risk behaviour has been well-documented, there is little understanding of whether marijuana use alone or combining marijuana with alcohol use contributes to sexual risk behaviour among adolescents. METHODS: A diverse sample of sexually active adolescents (n = 616) aged 12-18 years (50.32% Hispanic; 31.17% Black) completed a survey on alcohol use, marijuana use and sexual risk behaviour during a visit to a primary care clinic. RESULTS: Adolescents were more likely to report having had two or more sexual partners in the past 3 months if they reported using both alcohol and marijuana (OR=3.90, P<0.0001), alcohol alone (OR=2.51, P<0.0001) or marijuana alone (OR=1.89, P<0.001) compared with adolescents who reported no use during the past month. Adolescents were more likely to report having both two or more partners and condomless sex if they used both alcohol and marijuana (OR=3.19, P<0.001) or alcohol alone (OR=3.41, P<0.01) in the past month compared with adolescents who reported using marijuana alone or had no use of either. CONCLUSIONS: Providers should screen for both alcohol and marijuana use among adolescents and discuss how use of alcohol or alcohol in conjunction with marijuana may be associated with sexual risk behaviours.

Influence of mental health and alcohol or other drug use risk on adolescent reported care received in primary care settings.

BACKGROUND: To describe patterns of alcohol and other drug (AOD) use risk and adolescent reported primary care (PC) screening and intervention, and examine associations of AOD risk and mental health with reported care received. METHODS: We analyzed data from cross-sectional surveys collected from April 3, 2013 to November 24, 2015 from 1279 diverse adolescents ages 12-18 who reported visiting a doctor at least once in the past year. Key measures were AOD risk using the Personal Experience Screening Questionnaire; mental health using the 5-item Mental Health Inventory; binary measures of adolescent-reported screening and intervention. RESULTS: Half (49.2%) of the adolescents reported past year AOD use. Of the 769 (60.1%) of adolescents that reported being asked by a medical provider in PC about AOD use, only 37.2% reported receiving screening/intervention. The odds of reported screening/intervention were significantly higher for adolescents with higher AOD risk and lower mental health scores. CONCLUSIONS: Adolescents at risk for AOD use and poor mental health are most likely to benefit from brief intervention. These findings suggest that strategies are needed to facilitate medical providers identification of need for counseling of both AOD and mental health care for at risk youth.

Predictors of Retention in an Alcohol and Risky Sex Prevention Program for Homeless Young Adults.

Homeless young adults are at risk for alcohol and other drug (AOD) use and risky sexual behavior. Interventions are needed to help these young people reduce their risky behavior, but this population is often difficult to engage and retain in services. We offered a four-session AOD and risky sex reduction program to 100 participants and examined if retention in the program was predicted by a number of factors: demographics, homelessness severity, other service use, AOD behaviors, mental health symptoms, sexual risk behaviors, and readiness to change AOD and condom use. Nearly half (48%) of participants completed all sessions. In bivariate analyses, participants were significantly less likely to be retained in the program if they had slept outdoors in the past month, engaged in more alcohol and marijuana use, experienced more alcohol-related consequences, and received the program in an urban drop-in center (as opposed to a drop-in center near the beach). When controlling for all significant bivariate relationships, only sleeping outdoors and receipt of the program in the urban setting predicted fewer sessions completed. The most endorsed reasons for program non-completion were being too busy to attend and inconvenient day/time of the program. Findings can help outreach staff and researchers better prepare methods to engage higher risk homeless youth and retain them in services. Finding unique ways to help youth overcome barriers related to location of services appears especially necessary, perhaps by bringing services to youth where they temporarily reside or offering meaningful incentives for program attendance.

Ethnic Differences in Cigarette Use Trajectories and Health, Psychosocial, and Academic Outcomes.

PURPOSE: Cigarette smoking among youth is associated with poorer health and psychosocial outcomes. However, few studies address how smoking may differentially relate to the emergence of disparities in functioning across races/ethnicities over adolescence. METHODS: Youth (n = 2,509) were surveyed eight times from ages 11 to 18. We measured cigarette use, academic and social functioning, mental and physical health, and delinquency. Sequelae of change models controlled for sociodemographic factors, and tested whether intercept and slope for smoking trajectories were associated with outcomes at the end of high school, and examined racial/ethnic differences in outcomes assuming similar smoking trajectories across groups. RESULTS: Youth were 45% Hispanic, 20% Asian, 20% white, 10% multiethnic, 2% black, and 1% other ethnicities. Higher average probability of smoking and steeper slopes of smoking trajectories were associated with poorer outcomes in multiple domains. Controlling for smoking trajectories, we observed the following disparities (vs. white youth; all p's < .05): black, Hispanic, and multiethnic youth reported lower academic performance; Asian, black, and multiethnic youth reported higher academic unpreparedness; Asian and multiethnic youth reported poorer mental health; Asian, Hispanic, and multiethnic youth reported poorer physical health; and Asian youth reported higher delinquency and poorer social functioning. CONCLUSIONS: Statistically adjusting for similar smoking trajectories, racial/ethnic minority youth demonstrated poorer outcomes in multiple domains compared with white peers. Smoking may be a particularly robust marker for risk of negative outcomes in racial/ethnic minority youth. Screening for cigarette use and intervening on smoking and associated risk behaviors among minority youth may help reduce disparities in functioning.

Group motivational interviewing for homeless young adults: Associations of change talk with substance use and sexual risk behavior.

Homeless young adults exhibit high rates of alcohol and other drug (AOD) use and sexual risk behaviors. This study is a secondary analysis of data collected in a randomized clinical trial of AWARE, a new 4 session group motivational interviewing intervention. AWARE mainly focused on alcohol use and sexual risk behavior given focus group feedback. We used sequential coding to analyze how the group process affected both AOD use and sexual risk behavior at 3-month follow up among homeless young adults by examining facilitator behavior and participant change talk (CT) and sustain talk (ST). We analyzed 57 group session digital recordings of 100 youth (69% male, 74% heterosexual, 28% non-Hispanic white, 23% African American, 26% Hispanic, 23% multiracial/other; mean age 21.75). Outcomes included importance and readiness to change AOD use and risky sexual behavior, AOD use and consequences, number of partners and unprotected sex, and condom self-efficacy. Sequential analysis indicated that facilitator open-ended questions and reflections of CT increased Group CT. Group CT was associated with a lower likelihood of being a heavy drinker 3 months later; Group ST was associated with decreased readiness and confidence to change alcohol use. There were no associations with CT or ST for drug use or risky sexual behavior. Facilitator speech and peer responses were related to CT and ST during the group sessions with this high risk population, which were then associated with individual changes for alcohol use. Further research is needed to explore associations with drug use and sexual risk behavior. (PsycINFO Database Record

A group-based motivational interviewing brief intervention to reduce substance use and sexual risk behavior among homeless young adults.

Homeless young adults ages 18-25 exhibit high rates of alcohol and other drug (AOD) use, and sexual risk behaviors such as unprotected sex. Yet few programs exist for this population that are both effective and can be easily incorporated into settings serving this population. This pilot cluster cross-over randomized controlled trial evaluates AWARE, a voluntary four session group-based motivational interviewing (MI) intervention to reduce AOD use and sexual risk behavior. We evaluated AWARE with 200 homeless young adults using drop-in center services in Los Angeles County (mean age=21.8years; 73% male; 79% heterosexual; 31% non-Hispanic White, 25% African American, 24% Hispanic, 21% multiracial/other). Surveys were completed at baseline and three months after program completion. Retention in the AWARE program was excellent (79% attended multiple sessions) and participants reported high levels of satisfaction with the program. AWARE participants self-reported positive change in their past 3month and past 30day alcohol use (ps≤0.05), motivation to change drug use (ps<0.05), and condom use self-efficacy (p=0.05) compared to the control group. Among those with multiple sex partners, AWARE participants showed a decrease in unprotected sexual events (p<0.05), whereas the control group did not. Results from this pilot evaluation are promising, suggesting that a brief group-MI risk reduction intervention can be effective in helping homeless young adults make positive changes in their alcohol and condom use. Further work is needed to more fully evaluate the efficacy of AWARE on AOD behavior and sexual risk behavior outcomes.

Gender differences in the association between conduct disorder and risky sexual behavior.

Despite suggestions that there are gender differences in the association between conduct disorder (CD) and risky sexual behavior, limited empirical research has examined this question. Youth (N = 616) were recruited from four primary care clinics and completed questions related to risky sexual behavior, alcohol and marijuana use, and CD. Results of stratified multivariate models indicated that the association between CD and having four or more lifetime partners, having two or more partners in the last 3 months, and engaging in condomless sex was stronger among female youth. However, the association between CD and alcohol and other drug use before sex was stronger in male youth. This is an important contribution to our understanding of gender-specific manifestations of conduct disorder, and has the potential to inform screening and brief intervention efforts for this population.

The role of perceived injunctive alcohol norms in adolescent drinking behavior.

Peers have a major influence on youth during adolescence, and perceptions about peer alcohol use (perceived norms) are often associated with personal drinking behavior among youth. Most of the research on perceived norms among adolescents focuses on perceived descriptive norms only, or perceptions about peers' behavior, and correcting these perceptions are a major focus of many prevention programs with adolescents. In contrast, perceived injunctive norms, which are personal perceptions about peers' attitudes regarding the acceptability of behaviors, have been minimally examined in the adolescent drinking literature. Yet correcting perceptions about these perceived peer attitudes may be an important component to include in prevention programs with youth. Using a sample of 2493 high school-aged youth (mean age=17.3), we assessed drinking behavior (past year use; past month frequency, quantity, and peak drinks), drinking consequences, and perceived descriptive and injunctive norms to examine the relationships of perceived injunctive and descriptive norms on adolescent drinking behavior. Findings indicated that although perceived descriptive norms were associated with some drinking outcomes (past year use; past month frequency; past month quantity; peak drinks), perceived injunctive norms were associated with all drinking outcomes, including outcomes of consequences, even after controlling for perceived descriptive norms. Findings suggest that consideration of perceived injunctive norms may be important in models of adolescent drinking. Prevention programs that do not include injunctive norms feedback may miss an important opportunity to enhance effectiveness of such prevention programs targeting adolescent alcohol use.

Mindfulness Meditation for Chronic Pain: Systematic Review and Meta-analysis.

BACKGROUND: Chronic pain patients increasingly seek treatment through mindfulness meditation. PURPOSE: This study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults. METHOD: We conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use. RESULTS: Thirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life. CONCLUSIONS: While mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.

Frequency of E-cigarette Use, Health Status, and Risk and Protective Health Behaviors in Adolescents.

OBJECTIVES: E-cigarettes (ECs) are increasingly popular among adolescents, who perceive them as "safer" than cigarettes. Although research has examined risk factors for adolescent EC use, little is known about how EC use correlates with health status and protective health behaviors. METHODS: In all, 2488 adolescents (mean age = 17.31 years, SD = 0.67; 46% male) completed a survey on EC and cigarette use, physical and mental health, physical activity, diet, sleep, and alcohol and other drug (AOD) use. Logistic regression compared EC-only users to dual EC/cigarette users, cigarette-only users, and nonusers on these health factors. Among EC-only users, separate ordinary least-squares regression models assessed the effects of health status/behavior variables on frequency of past-year EC use, controlling for demographics and smokeless tobacco use. RESULTS: User groups were similar on physical health and engagement in protective health behaviors (physical activity, sleep duration/quality, healthy diet), but EC-only users reported fewer mental health symptoms and less AOD use than dual or cigarette-only users. Among EC-only users, AOD use (all P < 0.0001) predicted more frequent EC use; healthy diet predicted less frequent use (P < 0.01). CONCLUSIONS: EC-only use is associated with lower engagement in risky behaviors, but not better health status or higher engagement in protective health behaviors, compared with cigarette smoking. Dual EC/cigarette users may represent a particularly high-risk group due to their greater AOD use and cigarette consumption. Among "intermediate-risk" EC-only users, AOD use and unhealthy diet correlated with heavier use, and may be important targets for preventing escalation to more harmful tobacco use.

Screening in Primary Care: What Is the Best Way to Identify At-Risk Youth for Substance Use?

BACKGROUND: It is important to improve primary care providers' capability to identify youth at risk for alcohol and other drug use. To our knowledge, this is the first study to use Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria to compare screeners for youth for both alcohol and marijuana, given that these are the most frequently used substances by this age group. METHODS: We compared the psychometric performance of 4 screeners: the National Institute on Alcohol Abuse and Alcoholism Screening Guide (NIAAA SG), the Alcohol Use Disorders Identification Test, the Car-Relax-Alone-Forget-Family and Friends-Trouble (CRAFFT) screener, and the Personal Experience Screening Questionnaire Problem Severity Scale (PESQ-PS) in identifying alcohol and marijuana use outcomes. Youth age 12 through 18 (N = 1573; 27% black, 51% Hispanic) were screened with the NIAAA SG, followed by a Web survey that included the other screeners and outcomes. RESULTS: Sensitivity for alcohol outcomes indicated that the NIAAA SG (0.87) did not perform as well as the CRAFFT (0.97) or PESQ-PS (0.97) screeners but performed better than the Alcohol Use Disorders Identification Test (0.70). The pattern for sensitivity across screeners for marijuana outcomes was similar. CONCLUSIONS: An important tradeoff in primary care settings is precision versus practicality. Because of brevity and focus on frequency of drinking, the NIAAA SG offers ease of administration and is good at identifying youth with probably problematic drinking levels. The PESQ-PS and the CRAFFT correctly identify more at-risk youth for alcohol and marijuana than the NIAAA SG. Future work is needed to elucidate how to efficiently and accurately identify at-risk youth in the primary care setting, including determining the best cutoff points to use to increase sensitivity.

Alcohol mixed with energy drinks: Associations with risky drinking and functioning in high school.

BACKGROUND: Mixing alcohol with energy drinks is associated with heavier drinking and related problems among college students. However, little is known about how high school drinkers who mix alcohol with energy drinks (AmED) compare to those who do not (AwoED). This study compares high school AmED and AwoED users on their alcohol use during middle and high school, as well as key domains of functioning in high school. METHODS: Two surveys were conducted three years apart in adolescents initially recruited from 16 middle schools in Southern California. The analytic sample consists of 696 past month drinkers. Multivariable models compared AmED and AwoED users on alcohol use, mental health, social functioning, academic orientation, delinquency and other substance use at age 17, and on their alcohol use and related cognitions at age 14. RESULTS: AmED was reported by 13% of past month drinkers. AmED and AwoED users did not differ on alcohol use or cognitions in middle school, but AmED users drank more often, more heavily, and reported more negative consequences in high school. AmED users were also more likely to report poor grades, delinquent behavior, substance use-related unsafe driving, public intoxication, and drug use than AwoED users in high school. Group differences were not found on mental health, social functioning, or academic aspirations. CONCLUSIONS: AmED use is common among high school drinkers. The higher risk behavioral profile of these young AmED users, which includes drug use and substance use-related unsafe driving, is a significant cause for concern and warrants further attention.

Alcohol and marijuana use trajectories in a diverse longitudinal sample of adolescents: examining use patterns from age 11 to 17 years.

AIMS: We tested race/ethnic differences in alcohol and marijuana (AM) trajectories (comprising an intercept term, reflecting overall probability of use, and a slope term, reflecting change in probability of use) during adolescence, whether AM use trajectories predicted high school outcomes, and whether outcomes differed by race/ethnicity after controlling for trajectory of AM use. DESIGN: This longitudinal study involved 6509 youth from 16 middle schools in Southern California surveyed from age 11.5 (2008) to age 17 (2015) years; all surveys assessed AM use, and the final survey also examined high school outcomes. SETTING: Youth completed five surveys in middle school and two on-line surveys in high school. PARTICIPANTS: The sample was 50% male and 80% non-white. MEASUREMENTS: Intercept (at 2.75 years post-baseline) and slope of AM use were examined as outcomes for race/ethnic differences. AM use trajectories were examined as predictors of academic performance and unpreparedness, social functioning, mental and physical health and delinquency. FINDINGS: We found differences in trajectories of use by race/ethnicity, with white youth reporting a higher overall intercept of alcohol use compared to all other groups (versus Asian P < 0.001, black P = 0.001, multi-ethnic P = 0.008). Overall, examination of trajectories of use showed that adolescents with a higher alcohol use intercept term reported greater academic unpreparedness (P < 0.001) and delinquency (P < 0.001) at wave 7 in high school. In addition, youth with a higher intercept for marijuana use reported greater academic unpreparedness (P < 0.001) and delinquency (P < 0.001), and poorer academic performance (P = 0.032) and mental health (P = 0.002) in high school. At wave 7, compared to white youth, Hispanic and multi-ethnic youth reported poorer academic performance (P < 0.001 and P = 0.034, respectively); Asian, black and Hispanic youth reported higher academic unpreparedness (P < 0.001, P = 0.019, and P = 0.001); and Asian youth and multi-ethnic youth reported poorer physical health (P = 0.012 and P = 0.018) controlling for AM use. CONCLUSIONS: Greater AM use was associated with worse functioning in high school for all youth. After controlling for AM use, non-white youth reported worse outcomes in high school for academics and health.

Longitudinal Associations of Homophobic Name-Calling Victimization With Psychological Distress and Alcohol Use During Adolescence.

PURPOSE: Homophobic victimization, and specifically name-calling, has been associated with greater psychological distress and alcohol use in adolescents. This longitudinal study examines whether sexual orientation moderates these associations and also differentiates between the effects of name-calling from friends and nonfriends. METHODS: Results are based on 1,325 students from three Midwestern high schools who completed in-school surveys in 2012 and 2013. Linear regression analysis was used to examine the associations among homophobic name-calling victimization and changes in anxiety symptoms, depressive symptoms, and alcohol use one year later, controlling for other forms of victimization and demographics. RESULTS: Homophobic name-calling victimization by friends was not associated with changes in psychological distress or alcohol use among either students who self-identified as heterosexual or those who self-identified as lesbian, gay, or bisexual (LGB). In contrast, homophobic name-calling by nonfriends was associated with increased psychological distress over a one-year period among LGB students and increased drinking among heterosexual students. CONCLUSIONS: Homophobic name-calling victimization, specifically from nonfriends, can adversely affect adolescent well-being over time and, thus, is important to address in school-based bullying prevention programs. School staff and parents should be aware that both LGB and heterosexual adolescents are targets of homophobic name-calling but may tend to react to this type of victimization in different ways. Further research is needed to understand the mechanisms through which homophobic victimization increases the risk of psychological distress and alcohol use over time.

To Educate or To Incarcerate: Factors in Disproportionality in School Discipline.

The school-to-prison pipeline describes the process by which school suspension/expulsion may push adolescents into the justice system disproportionately based on race/ethnicity, socioeconomic status, and gender. The current study moves the field forward by analyzing a survey of a diverse sample of 2,539 students in 10th to 12th grade in Southern California to examine how demographic, individual, and family factors contribute to disparities in office referral and suspension/expulsion. African Americans, boys, and students whose parents had less education were more likely to be suspended/expelled. Higher levels of student academic preparation for class, hours spent on homework, and academic aspiration were associated with less school discipline. Findings suggest that helping students engage in school may be protective against disproportionate school discipline.

Early Substance Use and Subsequent DUI in Adolescents.

OBJECTIVE: Little is known about risk factors in early adolescence that lead to driving under the influence (DUI) and riding with a drinking driver (RWDD). In a diverse group of adolescents, we longitudinally explored the influence of alcohol and marijuana (AM) use, AM beliefs, and peer and family factors (including familism) on DUI/RWDD in high school. METHODS: We conducted 3 surveys 2 years apart of 1189 students recruited from 16 middle schools in Southern California. We used multivariable models to evaluate the effects of AM use, AM beliefs, and peer and family factors at ages 12 and 14 on DUI/RWDD at age 16. RESULTS: At age 12, adolescents with more positive beliefs about marijuana (odds ratio [OR] = 1.63, 95% confidence interval [CI]: 1.20-2.20) and more ability to resist marijuana offers (OR = 1.89, 95% CI: 1.22-2.92) had significantly higher risk of DUI/RWDD 4 years later. At age 14, youth with more past month alcohol use (OR = 2.10, 95% CI: 1.07-4.11), positive beliefs about marijuana (OR = 1.67, 95% CI: 1.31-2.13), exposure to peer AM use (alcohol: OR = 1.01, 95% CI: 1.00-1.02; marijuana: OR = 2.41, 95% CI: 1.28-4.53), and family marijuana use (OR = 1.54, 95% CI: 1.12-2.11) had higher risk of DUI/RWDD at age 16. CONCLUSIONS: Findings indicate a need to target adolescents as young as sixth grade at multiple levels to help prevent DUI/RWDD in high school. Given recent changes in legislation in several states, research should begin to focus on the distinction between DUI/RWDD of AM.

Predictors and consequences of prescription drug misuse during middle school.

OBJECTIVES: Non-medical prescription drug use (NMPDU) is a growing public health problem among adolescents. This is the first study to examine the correlates of early NMPDU initiation during middle school, and how early initiation is associated with four domains of functioning in high school (mental health, social, academic, and delinquency). METHODS: Students initially in 6th-8th grades from 16 middle schools completed in-school surveys between 2008 and 2011 (Waves 1-5), and a web-based survey in 2013-2014 (Wave 6). We used discrete time survival analysis to assess predictors of initiation from Waves 1 to 5 based on students who provided NMPDU information at any of these waves (n=12,904), and regression analysis to examine high school outcomes associated with initiation based on a sample that was followed into high school, Wave 6 (n=2539). RESULTS: Low resistance self-efficacy, family substance use, low parental respect, and offers of other substances from peers were consistently associated with NMPDU initiation throughout middle school. Further, perceiving that more of one's peers engaged in other substance use was associated with initiation at Wave 1 only. By high school, those students who initiated NMPDU during middle school reported lower social functioning, and more suspensions and fighting, compared to students who did not initiate NMPDU during middle school. CONCLUSION: NMPDU initiation during middle school is associated with poorer social functioning and greater delinquency in high school. It is important for middle school prevention programs to address NMPDU. Such programs should focus on both family and peer influences, as well as strengthening resistance self-efficacy.

A pilot study comparing in-person and web-based motivational interviewing among adults with a first-time DUI offense.

BACKGROUND: Driving under the influence (DUI) is a significant problem, and there is a pressing need to develop interventions that reduce future risk. METHODS: We pilot-tested the acceptance and efficacy of web-motivational interviewing (MI) and in-person MI interventions among a diverse sample of individuals with a first-time DUI offense. Participants (N = 159) were 65 percent male, 40 percent Hispanic, and an average age of 30 (SD = 9.8). They were enrolled at one of three participating 3-month DUI programs in Los Angeles County and randomized to usual care (UC)-only (36-h program), in-person MI plus UC, or a web-based intervention using MI (web-MI) plus UC. Participants were assessed at intake and program completion. We examined intervention acceptance and preliminary efficacy of the interventions on alcohol consumption, DUI, and alcohol-related consequences. RESULTS: Web-MI and in-person MI participants rated the quality of and satisfaction with their sessions significantly higher than participants in the UC-only condition. However, there were no significant group differences between the MI conditions and the UC-only condition in alcohol consumption, DUI, and alcohol-related consequences. Further, 67 percent of our sample met criteria for alcohol dependence, and the majority of participants in all three study conditions continued to report alcohol-related consequences at follow-up. CONCLUSIONS: Participants receiving MI plus UC and UC-only had similar improvements, and a large proportion had symptoms of alcohol dependence. Receiving a DUI and having to deal with the numerous consequences related to this type of event may be significant enough to reduce short-term behaviors, but future research should explore whether more intensive interventions are needed to sustain long-term changes.
