• When wanting to change is not enough: automatic appetitive processes moderate the effects of a brief alcohol intervention in hazardous-drinking college students
  Background: Research indicates that brief motivational interventions are efficacious treatments for hazardous drinking. Little is known, however, about the psychological processes that may moderate intervention success. Based on growing evidence that drinking behavior may be influenced by automatic (nonvolitional) mental processes, the current study examined whether automatic alcohol-approach associations moderated the effect of a brief motivational intervention. Specifically, we examined whether the efficacy of a single-session intervention designed to increase motivation to reduce alcohol consumption would be moderated by the strength of participants' automatic alcohol-approach associations. Methods: Eighty-seven undergraduate hazardous drinkers participated for course credit. Participants completed an Implicit Association Test to measure automatic alcohol-approach associations, a baseline measure of readiness to change drinking behavior, and measures of alcohol involvement. Participants were then randomly assigned to either a brief (15-minute) motivational intervention or a control condition. Participants completed a measure of readiness to change drinking at the end of the first session and returned for a follow-up session six weeks later in which they reported on their drinking over the previous month. Results: Compared with the control group, those in the intervention condition showed higher readiness to change drinking at the end of the baseline session but did not show decreased drinking quantity at follow-up. Automatic alcohol-approach associations moderated the effects of the intervention on change in drinking quantity. Among participants in the intervention group, those with weak automatic alcohol-approach associations showed greater reductions in the amount of alcohol consumed per occasion at follow-up compared with those with strong automatic alcohol-approach associations. Automatic appetitive associations with alcohol were not related with change in amount of alcohol consumed per occasion in control participants. Furthermore, among participants who showed higher readiness to change, those who exhibited weaker alcohol-approach associations showed greater reductions in drinking quantity compared with those who exhibited stronger alcohol-approach associations. Conclusions: The results support the idea that automatic mental processes may moderate the influence of brief motivational interventions on quantity of alcohol consumed per drinking occasion. The findings suggest that intervention efficacy may be improved by utilizing implicit measures to identify those who may be responsive to brief interventions and by developing intervention elements to address the influence of automatic processes on drinking behavior.

• Building the first step: a review of low-intensity interventions for stepped care
  Within the last 30 years, a substantial number of interventions for alcohol use disorders (AUDs) have received empirical support. Nevertheless, fewer than 25% of individuals with alcohol-related problems access these interventions. If several intensive psychosocial treatments are relatively effective, but most individuals in need do not access them, it seems logical to place a priority on developing more engaging interventions. Accordingly, after briefly describing findings about barriers to help-seeking, we focus on identifying an array of innovative and effective low-intensity intervention strategies, including telephone, computer-based, and Internet-based interventions, that surmount these barriers and are suitable for use within a stepped-care model. We conclude that these interventions attract individuals who would otherwise not seek help, that they can benefit individuals who misuse alcohol and those with more severe AUDs, and that they can facilitate subsequent help-seeking when needed. We note that these types of low-intensity interventions are flexible and can be tailored to address many of the perceived barriers that hinder individuals with alcohol misuse or AUDs from obtaining timely help. We also describe key areas of further research, such as identifying the mechanisms that underlie stepped-care interventions and finding out how to structure these interventions to best initiate a program of stepped care.

• Testing the effects of brief intervention in primary care for problem drug use in a randomized controlled trial: rationale, design, and methods
  Background: A substantial body of research has established the effectiveness of brief interventions for problem alcohol use. Following these studies, national dissemination projects of screening, brief intervention (BI), and referral to treatment (SBIRT) for alcohol and drugs have been implemented on a widespread scale in multiple states despite little existing evidence for the impact of BI on drug use for non-treatment seekers. This article describes the design of a study testing the impact of SBIRT on individuals with drug problems, its contributions to the existing literature, and its potential to inform drug policy. Methods: The study is a randomized controlled trial of an SBIRT intervention carried out in a primary care setting within a safety net system of care. Approximately 1000 individuals presenting for scheduled medical care at one of seven designated primary care clinics who endorse problematic drug use when screened are randomized in a 1:1 ratio to BI versus enhanced care as usual (ECAU). Individuals in both groups are reassessed at 3, 6, 9, and 12 months after baseline. Self-reported drug use and other psychosocial measures collected at each data point are supplemented by urine analysis and public health-related data from administrative databases.DiscussionThis study will contribute to the existing literature by providing evidence for the impact of BI on problem drug use based on a broad range of measures including self-reported drug use, urine analysis, admission to drug abuse treatment, and changes in utilization and costs of health care services, arrests, and death with the intent of informing policy and program planning for problem drug use at the local, state, and national levels.Trial registration: ClinicalTrials.gov NCT00877331

• Brief FASD prevention intervention: physicians' skills demonstrated in a clinical trial in Russia
  Background: Alcohol consumption during pregnancy can result in a range of adverse pregnancy outcomes including Fetal Alcohol Spectrum Disorders (FASD). Risky drinking among Russian women constitutes a significant risk for alcohol-exposed pregnancies (AEP). Russian women report that obstetrics and gynecology (OB/GYN) physicians are the most important source of information about alcohol consumption during pregnancy and developing effective prevention interventions is indicated. This is the first study focused on implementation of an AEP prevention intervention at women's clinics in Russia.MethodThe paper describes the intervention protocol and addresses questions about the feasibility of a brief FASD prevention intervention delivered by OB/GYN at women's clinics in Russia. Brief physician intervention guidelines and two evidence-based FASD prevention interventions were utilized to design a brief dual-focused physician intervention (DFBPI) appropriate to Russian OB/GYN care. The questions answered were whether trained OB/GYN physicians could feasibly deliver DFBPI during women's routine clinic visits, whether they maintained skills over time in clinical settings, and which specific intervention components were better maintained. Data were collected as part of a larger study aimed at evaluating effectiveness of DFBPI in reducing AEP risk in non-pregnant women. Methods of monitoring the intervention delivery included fidelity check lists (FCL) with the key components of the intervention completed by physicians and patients and live and audio taped observations of intervention sessions. Physicians (N= 23) and women (N= 372) independently completed FCL, and 78 audiotapes were coded. Results: The differences between women's and physicians' reports on individual items were not significant. Although the majority of physician and patient reports were consistent (N=305), a discrepancy existed between the reports in 57 cases. Women reported more intervention components missing compared to physicians (p<0.001). Discussing barriers was the most difficult component for physicians to implement, and OB/GYN demonstrated difficulties in discussing contraception methods. Conclusions: The results supported the feasibility of the DFBPI in Russia. OB/GYN physicians trained in the DFBPI, monitored, and supported were able to implement and maintain skills during the study. In addition to the alcohol focus, DFBPI training needs to have a sufficient component to improve physicians' skills in discussing contraception use.

• Qualitative analysis of cocaine and heroin users' main partner sex-risk behavior: is safety in love safety in health'
  Background: In 2009, 27% of the 48,100 estimated new cases of HIV were attributed to heterosexual contact with an infected or at-risk person. Sexually active adults are less likely to use condoms in relationships with main partners than with non-regular partners, despite general knowledge that condom use reduces HIV transmission. Methods: The purpose of this secondary qualitative analysis was to explore and contextualize perceptions of main partnerships, HIV risk, and attitudes toward condom use within main partner relationships among a subsample of intervention-arm cocaine- and/or heroin-using patients enrolled in a negative trial of brief motivational intervention to reduce the incidence of sexually transmitted disease and unsafe sexual behaviors. The open-ended portion of these interview audiotapes consisted of questions about perceptions of risk and attitudes about condom use with main partners. Enrollees were aged 18-54, English or Spanish speaking, and included in this analysis only if they reported having a main partner. We identified codes and elaborated important themes through a standard inductive three step coding process, using HyperRESEARCHTM software. Results: Among 48 interviewees, 65% were male, half were non-Hispanic white, over 60% were 20-39 years of age, 58% had intravenous drug use (IDU), and 8% were HIV-positive. Participants defined respect, support, trust, and shared child-rearing responsibility as the most valued components of main partner relationships. Condom use was viewed occasionally as a positive means of showing respect with main partners but more often as a sign of disrespect and a barrier to intimacy and affection. Enrollees appraised their partners' HIV risk in terms of perceptions of physical health, cleanliness, and sexual and HIV testing history. They based decisions regarding condom use mainly on perceived faithfulness, length of involvement, availability of condoms, and pregnancy desirability. Conclusions: Risk appraisal was commonly based on appearance and subjective factors, and condom use with main sexual partners was described most often as a demonstration of lack of trust and intimacy.Trial registration: NCT01379599

• Feasibility of a computer-assisted alcohol SBIRT program in an urban emergency department: patient and research staff perspectives
  Objectives: The study objective was to assess the feasibility of a computerized alcohol-screening interview (CASI) program to identify at-risk alcohol users among adult emergency department (ED) patients. The study aimed to evaluate the feasibility of implementing a computerized screening, brief intervention, and referral to treatment (SBIRT) program within a busy urban ED setting, to report on accurate deployment of alcohol screening results, and to assess comprehension and satisfaction with CASI from both patient and research staff perspectives. Methods: Research assistants (RAs) screened a convenience sample of medically stable ED patients. The RAs brought CASI to patients' bedsides, and patients entered their own alcohol consumption data. The CASI intervention consisted of an alcohol use screening identification test, a personalized normative feedback profile, NIAAA low-risk drinking educational materials, and treatment referrals (when indicated). Results: Five hundred seventeen patients were enrolled. The median age of participants was 37 years (range, 21-85 years); 37% were men, 62% were Hispanic, 7% were Caucasian, 30% were African American, and 2% were multiracial. Eighty percent reported regular use of computers at home. Eighty percent of patients approached consented to participate, and 99% of those who started CASI were able to complete it. Two percent of interviews were interrupted for medical tests and procedures, however, no patients required breaks from using CASI for not feeling well. The CASI program accurately provided alcohol risk education to patients 100% of the time. Thirty-two percent of patients in the sample screened positive for at-risk drinking. Sixty percent of patients reported that CASI increased their knowledge of safe drinking limits, 39% reported some likeliness to change their alcohol use, and 28% reported some intention to consult a health care professional about their alcohol use as a result of their screening results. Ninety-three percent reported CASI was easy to use, 93% felt comfortable receiving alcohol education via computer, and 89% liked using CASI. Ninety percent of patients correctly identified their alcohol risk level after participating in CASI. With regard to research staff experience, RAs needed to provide standby assistance to patients during <1% of CASI administrations and needed to troubleshoot computer issues in 4% of interviews. The RAs distributed the correct alcohol risk normative profiles to patients 97% of the time and provided patients with treatment referrals when indicated 81% of the time. The RAs rated patients as "not bothered at all" by using CASI 94% of the time. Conclusions: This study demonstrates that an ED-based computerized alcohol screening program is both acceptable to patients and effective in educating patients about their alcohol risk level. Additionally, this study demonstrates that few logistical problems related to using computers for these interventions were experienced by research staff: in most cases, staff accurately deployed alcohol risk education to patients, and in all cases, the computer provided accurate education to patients. Computer-assisted SBIRT may represent a significant time-saving measure, allowing EDs to reach larger numbers of patients for alcohol intervention without causing undue clinical burden or interruptions to clinical care. Future studies with follow-up are needed to replicate these results and assess drinking reductions post-intervention.

• Alcohol use disorder-related sick leave and mortality: a cohort study
  Background: Alcohol use disorders (AUDs) are associated with the highest all-cause mortality rates of all mental disorders. The majority of patients with AUDs never receive inpatient treatment for their AUD, and there is lack of data about their mortality risks despite their constituting the majority of those affected. Absenteeism from work (sick leave) due to an AUD likely signals worsening. In this study, we assessed whether AUD-related sick leave was associated with mortality in a cohort of workers in Germany. Methods: 128,001 workers with health insurance were followed for a mean of 6.4 years. We examined the associations between 1) AUD-related sick leave managed on an outpatient basis and 2) AUD-related psychiatric inpatient treatment, and mortality using survival analysis, and Cox proportional hazard regression models (separately by sex) adjusted for age, education, and job code classification. We also stratified analyses by sick leave related to three groups of alcohol-related conditions (all determined by International Classification of Diseases 9th ed. (ICD-9) codes): alcohol abuse and dependence; alcohol-induced mental disorder; and alcohol-induced medical conditions. Results: Outpatient-managed AUD-related sick leave was significantly associated with higher mortality (hazard ratio (HR) 2.90 (95% Confidence interval (CI) 2.24-3.75) for men, HR 5.83 (CI 2.90-11.75) for women). The magnitude of the association was similar for receipt of AUD-related psychiatric inpatient treatment (HR 3.2 (CI 2.76-3.78) for men, HR 6.5 (CI 4.41-9.47) for women). Compared to those without the conditions, higher mortality was observed consistently for outpatients and inpatients across the three groups of alcohol-related conditions. Those with alcohol-related medical conditions who had AUD-related psychiatric inpatient treatment appeared to have the highest mortality. Conclusions: Alcohol use disorder-related sick leave as documented in health insurance records is associated with higher mortality. Such sick leave does not necessarily lead to any specific AUD treatment. Therefore, AUD-related sick leave might be used as a trigger for insurers to intervene by offering AUD treatment to patients to try to reduce their risk of death.

• Screening and brief intervention for alcohol and other drug use in primary care: associations between organizational climate and practice
  Background: Numerous studies have demonstrated that positive organizational climates contribute to better work performance. Screening and brief intervention (SBI) for alcohol, tobacco, and other drug use has the potential to reach a broad population of hazardous drug users but has not yet been widely adopted in Brazil's health care system. We surveyed 149 primary health care professionals in 30 clinics in Brazil who were trained to conduct SBI among their patients. We prospectively measured how often they delivered SBI to evaluate the association between organizational climate and adoption/performance of SBI. Methods: Organizational climate was measured by the 2009 Organizational Climate Scale for Health Organizations, a scale validated in Brazil that assesses leadership, professional development, team spirit, relationship with the community, safety, strategy, and remuneration. Performance of SBI was measured prospectively by weekly assessments during the three months following training. We also assessed self-reported SBI and self-efficacy for performing SBI at three months post-training. We used inferential statistics to depict and test for the significance of associations. Results: Teams with better organizational climates implemented SBI more frequently. Organizational climate factors most closely associated with SBI implementation included professional development and relationship with the community. The dimensions of leadership and remuneration were also significantly associated with SBI. Conclusions: Organizational climate may influence implementation of SBI and ultimately may affect the ability of organizations to identify and address drug use.

• Perceived efficacy of e-cigarettes versus nicotine replacement therapy among successful e-cigarette users: a qualitative approach
  Background: Nicotine is widely recognized as an addictive psychoactive drug. Since most smokers are bio-behaviorally addicted, quitting can be very difficult and is often accompanied by withdrawal symptoms. Research indicates that nicotine replacement therapy (NRT) can double quit rates. However, the success rate for quitting remains low. E-cigarettes (electronic cigarettes) are battery-powered nicotine delivery devices used to inhale doses of vaporized nicotine from a handheld device similar in shape to a cigarette without the harmful chemicals present in tobacco products. Anecdotal evidence strongly suggests that e-cigarettes may be effective in helping smokers quit and preventing relapse, but there have been few published qualitative studies, especially among successful e-cigarette users, to support this evidence. Methods: Qualitative design using focus groups (N = 11); 9 men and 2 women. Focus groups were conducted by posing open-ended questions relating to the use of e-cigarettes, comparison of effectiveness between NRTs and e-cigarettes, barriers to quitting, and reasons for choosing e-cigarettes over other methods. Results: Five themes emerged that describe users' perceptions of why e-cigarettes are efficacious in quitting smoking: 1) bio-behavioral feedback, 2) social benefits, 3) hobby elements, 4) personal identity, and 5) distinction between smoking cessation and nicotine cessation. Additionally, subjects reported their experiences with NRTs compared with e-cigarettes, citing negative side effects of NRTs and their ineffectiveness at preventing relapse. Conclusion: These findings suggest tobacco control practitioners must pay increased attention to the importance of the behavioral and social components of smoking addiction. By addressing these components in addition to nicotine dependence, e-cigarettes appear to help some tobacco smokers transition to a less harmful replacement tool, thereby maintaining cigarette abstinence.

• Telephone care coordination for smokers in VA mental health clinics: protocol for a hybrid type-2 effectiveness-implementation trial
  Background: This paper describes an innovative protocol for a type-II hybrid effectiveness-implementation trial that is evaluating a smoking cessation telephone care coordination program for Veterans Health Administration (VA) mental-health clinic patients. As a hybrid trial, the protocol combines implementation science and clinical trial methods and outcomes that can inform future cessation studies and the implementation of tobacco cessation programs into routine care. The primary objectives of the trial are (1) to evaluate the process of adapting, implementing, and sustaining a smoking cessation telephone care coordination program in VA mental health clinics, (2) to determine the effectiveness of the program in promoting long-term abstinence from smoking among mental health patients, and (3) to compare the effectiveness of telephone counseling delivered by VA staff with that delivered by state quitlines. Methods: The care coordination program is being implemented at six VA facilities. VA mental health providers refer patients to the program via an electronic medical record consult. Program staff call referred patients to offer enrollment. All patients who enroll receive a self-help booklet, mailed smoking cessation medications, and proactive multi-call telephone counseling. Participants are randomized to receive this counseling from VA staff or their state's quitline. Four primary implementation strategies are being used to optimize program implementation and sustainability: blended facilitation, provider training, informatics support, and provider feedback. A three-phase formative evaluation is being conducted to identify barriers to, and facilitators for, program implementation and sustainability. A mixed-methods approach is being used to collect quantitative clinical effectiveness data (e.g., self-reported abstinence at six months) and both quantitative and qualitative implementation data (e.g., provider referral rates, coded interviews with providers). Summative data will be analyzed using the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework.DiscussionThis paper describes the rationale and methods of a trial designed to simultaneously study the clinical effectiveness and implementation of a telephone smoking cessation program for smokers using VA mental health clinics. Such hybrid designs are an important methodological design that can shorten the time between the development of an intervention and its translation into routine clinical care.Trial registration: ClinicalTrials.gov NCT00724308

• Randomized controlled trial to evaluate screening and brief intervention for drug-using multiethnic emergency and trauma department patients
  Background: Screening and brief intervention (SBI) is a comprehensive, integrated public health approach to identify and deliver a spectrum of early detection and intervention services for substance use in general medical care settings. Although the SBI approach has shown promise for alcohol use, relatively little is known about its effectiveness for illicit drug use. We are evaluating the SBI approach for drug use using a rigorous randomized controlled trial. The purpose of the report is to describe the overall trial and its programmatic and methodological strengths with a focus on health educator (HE) selection and training. In addition, the baseline characteristics of the recently enrolled multiethnic cohort are described. Methods: A randomized two-group repeated measures design is being used in which drug-related outcomes of an intervention group will be compared with those of an attention-placebo control group. Selection of bicultural paraprofessional HEs---their training in research concepts, comorbid mental health issues, special treatment of marijuana use, and nonscripted enhanced motivational interviewing as well as their ongoing monitoring and evaluation---are among the features described. The HEs enrolled, consented, and conducted an intervention among 700 illicit drug users in two large hospital emergency departments/trauma units. To be eligible, a participant needed to be an adult (age >=18 years), an English or Spanish speaker, awake and able to give consent, and reachable by telephone to schedule a six-month follow-up interview.DiscussionA comprehensive HE training protocol combined with rigorous, ongoing process measurement resulted in skill mastery in many areas and a successful participant recruitment period. Strengths and limitations of the study protocol are discussed as well as the characteristics of those recruited. This trial will be among the first to provide information about the effectiveness of SBI for illicit drug use. Outcome analysis has not yet been completed, but demonstrated programming and design successes have implications for future research and service delivery.Trial registration: NCT01683227

• Prolonged delusional state triggered by repeated ingestion of aromatic liquid in a past 5-methoxy-N, N-diisopropyltryptamine abuser
  A 30-year-old Japanese man with no previous psychiatric history presented to our facility with delusions, which had been ongoing for 2 months. Upon further interview, he confided that he had a past history of recurrent 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT or "Foxy") abuse, as well as a recent history of recurrent ingestion of a legal aromatic liquid used as a recreational drug. After this episode, his condition improved and he did not follow up at subsequent appointments. However, 6 months later, he suffered a relapse of prolonged delusions after again ingesting a recreational aromatic liquid. An evaluation of the chronological sequence of the patient's condition revealed that ingestion of these aromatic liquids, which can be purchased easily on the Internet, likely triggered the patient's delusional episodes. We speculate that the patient's recurrent abuse of 5-MeO-DIPT caused sensitization (or reverse tolerance), thus prolonging his delusions. Sensitization is the amplification of a response following repeated administrations of a stimulus. 5-MeO-DIPT is a popular drug of abuse, and it is highly probable that a large number of past 5-MeO-DIPT users are currently sensitized. This is an important latent factor underlying subsequent episode of drug-induced psychosis. Psychiatrists should consider the possibility of 5-MeO-DIPT sensitization when evaluating patients with acute psychoses.
