RESUMEN

Identifying clinical differences between opioid users (OU) and alcohol and other drug users (AOD) may help to tailor treatment to OU, particularly among the majority of OU who are not on opioid agonist treatments. Given the dearth of research on these differences, this study explored gender differences in demographic and clinical characteristics between OU and AOD. Participants (N = 506) were from a multisite, randomized controlled clinical trial of an Internet-delivered psychosocial intervention conducted in 2010-2011. Logistic regression models explored differences in demographic and clinical characteristics by substance use category within and between women and men. Women OU were more likely to be younger, White, employed, benzodiazepine users, and less likely to have children or use cocaine and cannabis than women AOD. Men OU, compared to men AOD, were more likely to be younger, White, younger at first abuse/dependence, benzodiazepine users, and reported greater psychological distress, but were less likely to be involved in criminal justice or use stimulants. Interactions by gender and substance use were also detected for age of first abuse/dependence, employment, and criminal justice involvement. These findings provide a nuanced understanding of gender differences within substance use groups to inform providers for OU seeking treatment.

RESUMEN

Abnormalities across different domains of neuropsychological functioning may constitute a risk factor for heavy drinking during adolescence and for developing alcohol use disorders later in life. However, the exact nature of such multi-domain risk profiles is unclear, and it is further unclear whether these risk profiles differ between genders. We combined longitudinal and cross-sectional analyses on the large IMAGEN sample (N ≈ 1000) to predict heavy drinking at age 19 from gray matter volume as well as from psychosocial data at age 14 and 19-for males and females separately. Heavy drinking was associated with reduced gray matter volume in 19-year-olds' bilateral ACC, MPFC, thalamus, middle, medial and superior OFC as well as left amygdala and anterior insula and right inferior OFC. Notably, this lower gray matter volume associated with heavy drinking was stronger in females than in males. In both genders, we observed that impulsivity and facets of novelty seeking at the age of 14 and 19, as well as hopelessness at the age of 14, are risk factors for heavy drinking at the age of 19. Stressful life events with internal (but not external) locus of control were associated with heavy drinking only at age 19. Personality and stress assessment in adolescents may help to better target counseling and prevention programs. This might reduce heavy drinking in adolescents and hence reduce the risk of early brain atrophy, especially in females. In turn, this could additionally reduce the risk of developing alcohol use disorders later in adulthood.

RESUMEN

Recognizing others' emotions is a fundamental social skill, widely impaired in psychiatric populations. These emotional dysfunctions are involved in the development and maintenance of alcohol-related disorders, but their differential intensity across emotions and their modifications during disease evolution remain underexplored. Affective prosody decoding was assessed through a vocalization task using six emotions, among 17 patients with severe alcohol use disorder, 16 Korsakoff syndrome patients (diagnosed following DSM-V criteria) and 19 controls. Significant disturbances in emotional decoding, particularly for negative emotions, were found in alcohol-related disorders. These impairments, identical for both experimental groups, constitute a core deficit in excessive alcohol use.

RESUMEN

BACKGROUND: Treatment for alcohol use disorders (AUDs) has traditionally been abstinence oriented, but new research and regulatory guidelines suggest that low-risk drinking may also be an acceptable treatment outcome. However, little is known about long-term outcomes for patients who become low-risk drinkers posttreatment. This study explores a posttreatment low-risk drinking outcome as a predictor of future drinking and psychosocial outcomes over 9 years. METHODS: Study participants were adults with AUDs at treatment entry who received follow-up interviews 6 months posttreatment intake (N = 1,061) in 2 large randomized studies conducted at Kaiser Permanente Northern California, a large private, nonprofit, integrated health system. Six-month drinking status was defined as abstinent, low-risk (nonabstinent, no 5+ drinking days), or heavy drinking (1 or more days of 5+ drinks). Using logistic regression models, we explored the relationship between past 30-day drinking status at 6 months and odds of being abstinent or a low-risk drinker (compared to heavy drinking), and positive Addiction Severity Index psychosocial outcomes over 9 years (9-year follow-up rate of 73%). RESULTS: Abstainers and low-risk drinkers at 6 months had higher odds of recent abstinence/low-risk drinking over 9 years than heavy drinkers; abstainers had better drinking outcomes than low-risk drinkers. Additionally, among those with interview data, 95% of abstainers and 94% of low-risk drinkers at 6 months were abstinent/low-risk drinkers at 9 years; surprisingly, 89% of heavy drinkers at 6 months were also abstinent/low-risk drinkers although still significantly fewer than the other groups. Abstainers and low-risk drinkers at 6 months had better psychiatric outcomes, and abstainers had better family/social outcomes than heavy drinkers; medical outcomes did not differ. Low-risk drinkers and abstainers showed no reliable differences across psychosocial measures. CONCLUSIONS: The findings suggest that a low-risk drinking outcome may be reasonable over the long-term for some alcohol-dependent individuals receiving addiction treatment.

RESUMEN

BACKGROUND: Favourable impacts are reported from complex alcohol control strategies, known as 'Alcohol Management Plans' (AMPs) implemented 14 years ago in 19 Aboriginal and Torres Strait Islander (Indigenous) communities in Queensland (Australia). However, it is not clear that all communities benefited and that positive impacts were sustained. Service providers, key stakeholders and community leaders provided insights about issues and impacts. METHODS: Participants (N=382) were recruited from knowledgeable and experienced persons using agency lists and by recommendation across sectors which have a mandate for managing alcohol-related issues and consequences of AMP policies in communities. In semi-structured interviews, participants (51% Indigenous, 55% male and comprised of at least one-third local community residents) were asked whether they believed alcohol controls had been effective and to describe any favourable and unfavourable outcomes experienced or perceived. Inductive techniques were used for thematic analysis of the content of transcribed recorded interviews. Comments reflecting themes were assessed across service sectors, by gender, Indigenous status and remoteness. RESULTS: Participants attributed reduced violence and improved community amenity to AMPs, particularly for 'very remote' communities. Participants' information suggests that these important achievements happened abruptly but may have become undermined over time by: the availability of illicit alcohol and an urgency to consume it; migration to larger centres to seek alcohol; criminalization; substitution of illicit drugs for alcohol; changed drinking behaviours and discrimination. Most issues were more frequently linked with 'very remote' communities. CONCLUSION: Alcohol restrictions in Queensland's Indigenous communities may have brought favourable changes, a significant achievement after a long period of poorly regulated alcohol availability from the 1980s up to 2002. Subsequently, over the past decade, an urgency to access and consume illicit alcohol appears to have emerged. It is not clear that relaxing restrictions would reverse the harmful impacts of AMPs without significant demand reduction, treatment and diversion efforts.

RESUMEN

Alcohol Behavioral Couple Therapy (ABCT) has emerged over the last 30 years as a highly efficacious treatment for those with alcohol use disorders. This review highlights the historical and conceptual underpinnings of ABCT, as well as the specific treatment elements and structure. Proposed active ingredients, moderators, and mediators of treatment outcome are discussed. Efficacy is evaluated for reductions in identified patient drinking, improved relationship functioning, and reductions in intimate partner violence. Adaptations of ABCT for substances other than alcohol are described. Other adaptations, including brief interventions, interventions addressing PTSD and TBI along with alcohol use, and interventions deliverable via technology platforms are described. Additional cost-benefit and cost-effectiveness findings supporting the economic value of ABCT are noted. Future directions for research in this area include possible adaptations for female identified patients, nontraditional couples, LGBT partners and dyads involving nonintimate partner relationships. The development of more flexible models and enhanced dissemination strategies may improve clinical uptake and utility as well as increasing the feasibility of this treatment for integrated healthcare settings.

RESUMEN

OBJECTIVES: The present study assessed combinations of spirituality/religiosity (S/R), a known protective factor against heavy drinking, with drinking motives, and alcohol-related ambivalence to better understand how these factors interrelate and are associated with drinking and alcohol-related problems. METHODS: Participants were 241 heavy drinking undergraduate students (81.74% female; Mage=23.48years; SD=5.50) who completed study questionnaires online. RESULTS: Coping, enhancement, and conformity drinking motives were associated with greater alcohol use and problems, however there were no main effects of either ambivalence or S/R on alcohol outcomes. S/R interacted with ambivalence with respect to drinking and problems. S/R also interacted with conformity drinking motives with respect to drinking and problems. Further, ambivalence interacted with conformity drinking motives regarding problems. Three-way interactions emerged between ambivalence, S/R, and drinking motives (social, coping, and enhancement motives) regarding drinking and problems. Results show that individuals at highest risk for problematic drinking are those who more strongly endorse drinking motives, are low in S/R, and high in ambivalence. CONCLUSIONS: Findings supported hypotheses and provide support for clusters of individual difference factors that put heavy drinking college students at higher risk for problematic drinking. These examinations have practical utility and may inform development and implementation of interventions and programs targeting alcohol misuse among heavy drinking undergraduate students.

RESUMEN

Metacognitive therapy is designed to impact directly on cognitive monitoring and control processes such that individuals can develop alternative ways of experiencing and regulating thoughts. One technique used for this purpose is 'detached mindfulness' which promotes a decentred perspective to thoughts and decouples repetitive thinking and coping from their occurrence. This study set out to test the effects of detached mindfulness against a control condition, a brief exposure to alcohol-related thoughts. Eight patients diagnosed with alcohol use disorder in an abstinence regime were exposed to detached mindfulness versus brief exposure in a counterbalanced repeated-measures design. Results showed that detached mindfulness led to significantly greater decreases in meta-appraisal and metacognitive beliefs about alcohol-related thoughts compared to a brief exposure. Significantly greater decreases in distress and urge to use alcohol were also observed in detached mindfulness. The clinical implications are discussed.

RESUMEN

BACKGROUND: Approximately 15 million persons in the European Union and 10 million persons in the USA are alcohol-dependent. The global burden of disease and injury attributable to alcohol is considerable: worldwide, approximately one in 25 deaths in 2004 was caused by alcohol. At the same time, alcohol use disorders remain seriously undertreated. In this context, alternative or adjunctive therapies such as brain stimulation may play a prominent role. The early results of studies using transcranial direct current stimulation found that stimulations delivered to the dorsolateral prefrontal cortex result in a significant reduction of craving and an improvement of the decision-making processes in various additive disorders. We, therefore, hypothesize that transcranial direct current stimulation can lead to a decrease in alcohol consumption in patients suffering from alcohol use disorders. METHODS/DESIGN: We report the protocol of a randomized, double-blind, placebo-controlled, parallel-group trial, to evaluate the efficacy of transcranial direct current stimulation on alcohol reduction in patients with an alcohol use disorder. The study will be conducted in 14 centers in France and Monaco. Altogether, 340 subjects over 18 years of age and diagnosed with an alcohol use disorder will be randomized to receive five consecutive twice-daily sessions of either active or placebo transcranial direct current stimulation. One session consists in delivering a current flow continuously (anode F4; cathode F3) twice for 13 minutes, with treatments separated by a rest interval of 20 min. Efficacy will be evaluated using the change from baseline (alcohol consumption during the 4 weeks before randomization) to 24 weeks in the total alcohol consumption and number of heavy drinking days. Secondary outcome measures will include alcohol craving, clinical and biological improvements, and the effects on mood and quality of life, as well as cognitive and safety assessments, and, for smokers, an assessment of the effects of transcranial direct current stimulation on tobacco consumption. DISCUSSION: Several studies have reported a beneficial effect of transcranial direct current stimulation on substance use disorders by reducing craving, impulsivity, and risk-taking behavior, and suggest that transcranial direct current stimulation may be a promising treatment in addiction. However, to date, no studies have included sufficiently large samples and sufficient follow-up to confirm the hypothesis. Results from this large randomized controlled trial will give a better overview of the therapeutic potential of transcranial direct current stimulation in alcohol use disorders.

RESUMEN

BACKGROUND: Injury related to self-harm is one of the leading causes of global disease burden. As a formative work for a programme to implement comprehensive mental healthcare in a rural district in Ethiopia, we determined the 12-month prevalence of non-fatal suicidal behaviour as well as factors associated with this behaviour to understand the potential burden of the behaviour in the district. METHOD: Population-based (n = 1485) and facility-based (n = 1014) cross-sectional surveys of adults, using standardised, interview-based measures for suicidality (items on suicide from the Composite International Diagnostic Interview), depressive symptoms (the Patient Health Questionnaire) and alcohol use disorders (Alcohol Use Disorder Investigation Test; AUDIT). RESULTS: The overall 12-month prevalence of non-fatal suicidal behaviour, consisting of suicidal ideation, plan and attempt, was 7.9 % (95 % Confidence Interval (CI) = 6.8 % to 8.9 %). The prevalence was significantly higher in the facility sample (10.3 %) compared with the community sample (6.3 %). The 12-month prevalence of suicide attempt was 4.4 % (95 % CI = 3.6 % to 5.3 %), non-significantly higher among the facility sample (5.4 %) compared with the community sample (3.8 %). Over half of those with suicidal ideation (56.4 %) transitioned from suicidal ideation to suicide attempt. Younger age, harmful use of alcohol and higher depression scores were associated significantly with increased non-fatal suicidal behaviours. The only factor associated with transition from suicidal ideation to suicide attempt was high depression score. Only 10.5 % of the sample with suicidal ideation had received any treatment for their suicidal behaviour: 10.8 % of the community sample and 10.2 % of the facility sample. Although help seeking increased with progression from ideation to attempt, there was no statistically significant difference between the groups. CONCLUSION: Non-fatal suicidal behaviour is an important public health problem in this rural district. A more in-depth understanding of the context of the occurrence of the behaviour, improving access to care and targeting depression and alcohol use disorder are important next steps. The role of other psychosocial factors should also be explored to assist the provision of holistic care.

RESUMEN

Compromised dopamine signaling in the striatum has been associated with the expression of impulsive behaviors in addiction, obesity and alcoholism. In rodents, intragastric infusion of the fatty acid amide oleoylethanolamide increases striatal extracellular dopamine levels via vagal afferent signaling. Here we tested whether supplementation with PhosphoLean™, a dietary supplement that contains the precursor of the fatty acid amide oleoylethanolamide (N-oleyl-phosphatidylethanolamine), would reduce impulsive responding and alcohol use in heavy drinking young adults. Twenty-two individuals were assigned to a three-week supplementation regimen with PhosphoLean™ or placebo. Impulsivity was assessed with self-report questionnaires and behavioral tasks pre- and post-supplementation. Although self-report measures of impulsivity did not change, supplementation with PhosphoLean™, but not placebo, significantly reduced false alarm rate on a Go/No-Go task. In addition, an association was found between improved sensitivity on the Go/No-Go task and reduced alcohol intake. These findings provide preliminary evidence that promoting fatty acid derived gut-brain dopamine communication may have therapeutic potential for reducing impulsivity in heavy drinkers.

RESUMEN

Distinct environmental and conditioned stimuli influencing ethanol-associated appetitive and consummatory behaviors may jointly contribute to alcohol addiction. To develop an effective translational animal model that illuminates this interaction, daily seeking responses, maintained by alcohol-associated conditioned stimuli (CSs), need to be dissociated from alcohol drinking behavior. For this, we established a procedure whereby alcohol seeking maintained by alcohol-associated CSs is followed by a period during which rats have the opportunity to drink alcohol. This cue-controlled alcohol-seeking procedure was used to compare the effects of naltrexone and GSK1521498, a novel selective µ-opioid receptor antagonist, on both voluntary alcohol-intake and alcohol-seeking behaviors. Rederived alcohol-preferring, alcohol-nonpreferring, and high-alcohol-drinking replicate 1 line of rats (Indiana University) first received 18 sessions of 24 h home cage access to 10% alcohol and water under a 2-bottle choice procedure. They were trained subsequently to respond instrumentally for access to 15% alcohol under a second-order schedule of reinforcement, in which a prolonged period of alcohol-seeking behavior was maintained by contingent presentations of an alcohol-associated CS acting as a conditioned reinforcer. This seeking period was terminated by 20 min of free alcohol drinking access that achieved significant blood alcohol concentrations. The influence of pretreatment with either naltrexone (0.1-1-3 mg/kg) or GSK1521498 (0.1-1-3 mg/kg) before instrumental sessions was measured on both seeking and drinking behaviors, as well as on drinking in the 2-bottle choice procedure. Naltrexone and GSK1521498 dose-dependently reduced both cue-controlled alcohol seeking and alcohol intake in the instrumental context as well as alcohol intake in the choice procedure. However, GSK1521498 showed significantly greater effectiveness than naltrexone, supporting its potential use for promoting abstinence and preventing relapse in alcohol addiction.

RESUMEN

Alcohol and cannabis are the primary substances contributing to referrals of adolescents to substance abuse treatment services. Their outcome has not been examined in Ireland. A three month follow-up was conducted in an outpatient adolescent treatment program. We followed up 35 high risk users of alcohol and 55 high risk users of cannabis. Although the high risk drinkers achieved a significant reduction in median number of days drinking (p = 0.004), only four (11 %) were abstinent at follow up. A further five (14%) achieved a reliable reduction in days of drinking. The high risk cannabis users demonstrated a significant drop in median days of use (p < 0.001), although only six (11%) were abstinent at follow up. A further 20 (36%) achieved a reliable reduction in days of use. Calculation of reliable change allows examination of outcomes which fall short of the elusive goal of abstinence.

RESUMEN

This article describes the design, implementation, and evaluation of a clinical pathway system in a two-cohort quasi-experimental study before and after implementation, controlling for confounders. The main outcome measures were retention in care and sensible alcohol use (defined as abstinent or drinking no more than 21 standard drinks per week). Patients with harmful alcohol use or dependence as their primary problem who were seeking psychosocial treatment at one of four alcohol clinics in Denmark participated in the study. After implementation of the clinical pathway system, which incorporated a structured intake, a referral and independent follow-up system, checklists, audit, and feedback, there was no change in length of stay, but significantly more patients had a good clinical outcome (stopped or moderated their consumption) at the end of treatment (OR = 1.9; 1.2-3.1). The study documents the feasibility of using a clinical pathway framework, incorporating a local monitoring system, checklists, audit, and feedback to enhance treatment quality and improve outcomes for alcohol use disorders.

RESUMEN

Reports of functional problems are common among Veterans who served post-9/11 (more than 25% report functional difficulties in at least one domain). However, little prospective work has examined the risk and protective factors for functional difficulties among Veterans. In a sample of recently separated Marines, we used stepwise logistic and multiple regressions to identify predictors of functional impairment, including work-related problems, financial problems, unlawful behavior, activity limitations due to mental health symptoms, and perceived difficulty reintegrating into civilian life. Posttraumatic stress disorder symptoms assessed both before and after military separation significantly predicted functional difficulties across all domains except unlawful behavior. Certain outcomes, such as unlawful behavior and activity limitations due to mental health symptoms, were predicted by other or additional predictors. Although several forms of functioning were examined, the list was not exhaustive. The results highlight a number of areas where targeted interventions may facilitate the reintegration of military servicemembers into civilian life.

RESUMEN

BACKGROUND: Alcohol Management Plans (AMPs) were first implemented by the Queensland Government a decade ago (2002-03). In 2008, further stringent controls were implemented and alcohol was effectively prohibited in some of the affected remote Indigenous communities. With the Queensland Government currently reviewing AMPs, prohibitions may be lifted making alcohol readily available once more in these communities. As yet no work explores the impact of alcohol related injuries in relation to individual, family and community resilience in Indigenous Australians. A resilience model recognises individuals and families for their strengths rather than their deficits. By revealing how some individuals and families survive and thrive, new ways of working with families who need support may be identified and adopted. The research will explore in detail the long-term impact of this kind of injury on individuals, families and communities. METHODS/DESIGN: This project will use a sequential explanatory mixed method design. Four discrete Indigenous communities in Cape York, far north Queensland are included in this program of research, chosen because there is previous data available regarding injury and alcohol related injuries. Four sequential studies will be conducted in order to address the research questions and provide a rich description of the impact of alcohol related injuries and resilience in these populations. The time period January 2006 to December 2011 was chosen because it captures the three years before and three years after 2008 when tight alcohol restrictions were implemented in the four communities. DISCUSSION: Long term effects of the AMPs are as yet unknown and only fragmented attempts to look at the impact of injury related to alcohol have been conducted. A well-structured research program that explores the long-term impact of alcohol related injuries in these communities will help inform policy development to capture the current situation and so that appropriate benchmarking can occur.The project has been approved by the James Cook University Human Research Ethics Committee H5618 & H5241.

RESUMEN

To determine the association between individual substances of abuse and antiretroviral adherence, analyses require a large sample assessed using electronic data monitoring (EDM). In this analysis, EDM data from 1,636 participants in 12 US adherence-focused studies were analyzed to determine the associations between recent use of various substances and adherence during the preceding 4 weeks. In bivariate analyses comparing adherence among patients who had used a specific substance to those who had not, adherence was significantly lower among those who had recently used cocaine, other stimulants or heroin but not among those who had used cannabis or alcohol. In multivariate analyses controlling for sociodemographics, amount of alcohol use and recent use of any alcohol, cocaine, other stimulants and heroin each was significantly negatively associated with adherence. The significant associations of cocaine, other stimulants, heroin, and alcohol use with adherence suggest that these are important substances to target with adherence-focused interventions.

RESUMEN

Distress tolerance refers to the degree to which an individual is able to withstand negative psychological and/or physical states. Empirical literature has indicated that lower distress tolerance is associated with a number of negative alcohol and other drug (AOD) use outcomes and psychopathology. Mindfulness meditation focuses on enhancing affect regulation, and may be particularly beneficial for individuals with lower distress tolerance. This secondary analysis evaluated the basic psychometric properties of the Distress Tolerance Scale (DTS) in a clinical sample of individuals with AOD-use disorders and tested whether distress tolerance for negative psychological states moderated treatment effects on AOD outcomes in an initial efficacy trial of mindfulness-based relapse prevention (MBRP). It was hypothesized that participants with lower distress tolerance would report fewer AOD use days over the 4-month follow-up if they received MBRP versus treatment as usual (TAU). Participants (N=168) in the parent RCT were recruited from a private, nonprofit agency providing inpatient and outpatient care for individuals with AOD-use disorders. Assessments of 60-day frequency of AOD use, as measured by the Timeline Followback, were conducted at baseline, immediately postintervention, and 2months and 4months following the intervention. Distress tolerance, as measured by the DTS, was assessed at baseline. Results indicated a one-factor solution, which is consistent with how the DTS has been implemented in other studies. As predicted, DTS was positively associated with all mindfulness subscales, suggesting its convergent validity in this clinical sample. Findings showed the hypothesized time×treatment×distress tolerance interaction, and thereby indicated that participants with lower distress tolerance who received MBRP treatment experienced a greater curvilinear decrease in AOD use days over time than those with lower distress tolerance who received TAU. However, the observed plateau effect suggests that these effects were not maintained at the 4-month follow-up. Findings suggest that distress tolerance is a clinically relevant client characteristic to consider in matching participants to aftercare treatment and that MBRP may be particularly helpful for individuals with lower distress tolerance.

RESUMEN

OBJECTIVE: The purpose of this research was to investigate whether factors associated with first obtaining care for alcohol problems vary by source of care. METHOD: This study used data from the National Epidemiologic Survey on Alcohol and Related Conditions to examine initiation of different types of care over a 3-year follow-up interval among individuals with baseline alcohol use disorders who had not previously obtained any care (n = 2,170). Three hierarchical, mutually exclusive types of care were compared: substance use disorder (SUD) specialty sources, general medical but no SUD specialty sources, and nonmedical sources only. RESULTS: Having injured oneself or someone else because of drinking was associated with initiating all three types of care. Additional factors associated with initiating care from SUD specialty treatment sources (vs. no care) comprised male sex, alcohol use disorder severity, major financial problems, and nondependent tobacco/drug use. Factors associated with initiating care from general medical but not SUD specialty sources (vs. no care) comprised marriage/cohabitation, college student status, number of medical conditions, and other substance dependence. Factors associated with obtaining care only from nonmedical sources (vs. no care) comprised low income and anxiety disorder. When direct comparisons were made among types of care, factors drawing individuals into general medical care for reasons not necessarily related to alcohol problems were those that primarily distinguished utilization of general medical sources from the other two types of care. CONCLUSIONS: Results support the importance of screening in general medical practice and student health services as an important means of identifying individuals in need of brief intervention or more intensive SUD treatment and reiterate the importance of nonmedical sources for individuals whose alcohol problems might never be addressed in routine medical visits.

RESUMEN

OBJECTIVE: The alcoholism research literature has long reported a significant, reliable, and inverse association between alcohol use disorders and religion/spirituality (R/S), and this is also evident in the period of highest risk--adolescence and young adulthood. In the treatment area, both clinical and mutual-help programs for alcohol use disorders often include a spiritual component, and outcome studies validate the efficacy of such programs. Even so, the alcoholism-R/S relationship is little understood. METHOD: The current study examined data from an existing sample of 4,002 female adolescents/young adults and their families. Data analyses examined five demographic, nine R/S, and eight risk-factor variables as predictors of five alcohol milestones: initial drink, first intoxication, regular use, heavy consumption, and alcohol dependence. RESULTS: Results affirmed the known association between alcoholism risk factors and alcohol use milestones and also found moderate to strong associations between most R/S variables and these risk factors and milestones. A multivariate model simultaneously examining both sets of variables found that specific risk factors and specific R/S variables remained significant predictors of alcohol use milestones after accounting for all other variables. Mediation and moderation tests did not find evidence that R/S accounted for or qualified the relationship between alcohol risk factors and alcohol milestones. CONCLUSIONS: This study confirmed the multidimensional role of R/S influences within the etiological network of alcoholism risk and protective factors in adolescents/young adults and found R/S dimensions to be independent and substantial influences on alcohol use disorders rather than mediators or moderators of other risks.
