An International Comparison of a Web-Based Personalized Feedback Intervention for Alcohol use During the Transition out of High School in the United States and Sweden.

Young adult drinkers engage in a range of drinking patterns from abstaining to heavy drinking in both the United States and Sweden. Heavy drinking during young adulthood in both countries is associated with a variety of negative consequences. Personalized feedback interventions have been identified as effective prevention strategies to prevent or reduce heavy drinking in the United States. This study examined transitions in drinking profiles and compared the efficacy of a personalized feedback intervention for 3965 young adults in the United States (1,735) and Sweden (2230) during their transition out of high school. Using goodness-of-fit criteria, results indicated that three drinking profiles exist among young adults transitioning out of high school: very low drinkers/abstainers, moderate to heavy drinkers, and very heavy drinkers. Latent Markov models revealed a moderating effect of country on personalized feedback intervention such that intervention condition participants in the United States were more likely to belong to the light drinker/abstainer or moderate to heavy profile relative to the very heavy drinking profile at 6-month follow-up. There was no significant effect of personalized feedback intervention in Sweden. Future research could investigate the impact of when personalized feedback interventions are administered and could examine if personalized feedback interventions should be more intentionally culturally adapted in order to be more effective.

Daily Assessment of Acute Dynamic Risk in Paroled Offenders: Prediction, Predictive Accuracy and Intervention Effect.

Few studies have assessed acute dynamic risk repeatedly among paroled offenders to investigate the relationship between changes in acute dynamic risk and recidivism in crime. The present study investigates whether one-month changes in ten stress-related acute dynamic risk factors, collected through automated telephony while the participants were still in prison and over 30 consecutive days following parole, predict one-year criminal recidivism, including its predictive accuracy. The study also investigates whether a brief feedback intervention in conjunction with the daily assessments reduces recidivism compared to an assessment-only control group. Changes in five risk factors were found to be associated with increased risk of criminal recidivism after controlling for the results in prison, the initial value after parole, and the intervention. The predictive accuracy is marginally accurate: Summary score (AUC) = .666; Level of stress (AHSS) = .644; Psychiatric symptoms (SCL-8D) = .641; Anxiety symptoms = .673; Severity of most stressful daily event = .690. No differences in one-year recidivism rates were established between the intervention group and the control group. The study shows that daily assessments can usefully be made of dynamic risk factors in paroled offenders.

Non-medical prescription drug use (NMPDU) and poor quality of life in the Swedish general population.

BACKGROUND AND OBJECTIVES: Quality of life has become an increasingly important measurement in the substance use field. The main aim of the present study was to examine the relationships between non-medical use of prescription analgesics and sedatives and poor quality of life in the general population. METHODS: Data were drawn from a Swedish national household survey conducted in 2008-2009. A stratified sample of 58,000 individuals aged 15-64 was randomly selected, with a response rate of 38.3% (n = 22,095). We examined the relationships between non-medical prescription drug use and quality of life in a logistic regression analysis, controlling for other substance use and sociodemographic variables. RESULTS: In the final logistic regression model, both non-medical use of prescription analgesics and sedatives were independently associated with poor quality of life. Non-medical use of prescription sedatives was the strongest correlate of poor quality of life among the substance use variables. DISCUSSION AND CONCLUSIONS: The associations between non-medical prescription drug use and poor quality of life might imply a need to better identify and provide treatment for this group, especially individuals with non-medical prescription sedative use, which seems to be a particularly strong correlate of poor quality of life. SCIENTIFIC SIGNIFICANCE: Using a large, general population sample, the present paper is one of few to examine the relationships between non-medical prescription drug use and quality of life.

Mortality, attempted suicide, re-hospitalisation and prescription refill for clozapine and other antipsychotics in Sweden-a register-based study.

PURPOSE: The aim of this study was to analyse prescription refill, re-hospitalisation, total mortality, mortality because of suicide and attempted suicide among patients who were taking various types of antipsychotics. METHODS: A population-based cohort study analysed all patients (n=26046) in Sweden who had been treated for schizophrenia from 2006 to 2009 with regard to re-hospitalisation and prescription refill for various types of antipsychotic treatment. A case-control study nested within the cohort analysed all-cause mortality, mortality because of suicide and attempted suicide in relation to antipsychotic use. The study adjusted for history of hospitalisation for psychiatric and medical care, attempted suicide and use of antidepressants. RESULTS: Aripiprazole users were the only ones who showed significantly lower all-cause risks of death, but so few events occurred among users of this relatively new drug that the results should be interpreted with caution. Clozapine users showed lower odds of death by suicide (odds ratio [OR]=0.45 [95%CI 0.20-0.98]) and of attempted suicide (OR=0.44 [0.28-0.70]) than haloperidol users after adjustment for age, sex and year of discharge. Olanzapine users showed approximately the same favourable pattern. Patients who used clozapine were most likely to refill prescriptions and had lower rates of re-hospitalisation. Only one death and 23 cases of agranulocytosis were reported compared with 223 suicides and 831 suicide attempts. An etiologic fraction calculation suggests that the use of clozapine rather than traditional drugs could have prevented 95 suicide attempts during the period. CONCLUSION: Clozapine and olanzapine reduce the risk of suicide, attempted suicide and re-hospitalisation.

Alcohol and drug use in groups of cannabis users: results from a survey on drug use in the Swedish general population.

BACKGROUND AND OBJECTIVES: Although cannabis is well studied in the scientific literature, relatively little is known about the relationship between the frequency of cannabis use and the use of alcohol and other drugs. The aim of this study was to identify differences between frequent and occasional cannabis users with respect to the use of other illicit drugs, hazardous alcohol use, and unauthorized use of prescription drugs. METHODS: Results from a questionnaire on drug use taken by 22,095 individuals in the Swedish general population were analyzed with a logistic regression model. Active cannabis use was defined as having used cannabis in the past 12 months. Use of cannabis two-to-three times per week or more was classified as frequent use. RESULTS: Cannabis users were more likely to report hazardous alcohol use, use of other illicit drugs, and unauthorized use of prescription drugs than were non-users. Within the group of active cannabis users, frequent cannabis use, compared to occasional use, was associated with the use of other illicit drugs and negatively associated with hazardous alcohol use. DISCUSSION AND CONCLUSIONS: The association between cannabis use and hazardous alcohol use, use of other illicit drugs, and unauthorized use of prescription drugs was expected. However, the negative association between frequent cannabis use and hazardous alcohol use among active cannabis users was surprising. This indicates that frequent cannabis users may differ from more occasional users in clinical needs. SCIENTIFIC SIGNIFICANCE: These results show a previously unknown characteristic of the association between frequency of cannabis use and hazardous alcohol use in the general population.

The AVI-R2: an inventory for a differentiated diagnosis of alcohol problems.

Often in clinical practice, a diagnosis of alcohol dependence or abuse does not provide enough information to establish an adequate treatment plan. Hence, multidimensional instruments have been constructed better to describe the extent and character of a patient's alcohol problem. The purpose of the current article is to present the AVI-R2, a self-report test that provides a standardized and differentiated description of an ongoing drinking problem. The instrument includes 81 items categorized into 16 primary scales that were further summarized into four secondary scales: alcohol dependence, psychological benefits, relational complications and multiple dependence. The article provides reference values and psychometric properties of the Swedish version of the test. Data were based on 270 alcoholic patients recruited from the Centre for Dependency Disorders in Stockholm. Except for one primary scale (social complications due to drinking), the psychometric properties of the test were satisfactory. Recommendations on when and how the test can be used were also provided.

Case management in aftercare of involuntarily committed patients with substance abuse. A randomized trial.

OBJECTIVE: Case management has since the 1970s been widely used to co-ordinate services for mental health patients. The methodology has expanded to support patients in many different types of conditions. This study is one of very few randomized trials on case management in a European setting. It examined the impact of case management on substance abuse and use of service after discharge from court-ordered institutional care. METHODS: Court-ordered patients with substance abuse ( n = 36) were randomly assigned to either strengths based case management or treatment-as-usual during 6 months in aftercare. Data was collected at intake, at conclusion of intervention and at 6 month's follow-up with a follow-up rate of 94%. RESULTS: Case management interventions were well received by the patients with no drop-out during intervention. Patients with the support of a case manager seemed to sustain abstinence in a higher degree compared with treatment-as-usual but no differences were detected in regard to use of care. A subgroup analysis showed that patients with a continuous drug abuse did have access to care from both social welfare and hospital care systems. CONCLUSIONS: Case management may be useful in order to retain abstinence in aftercare following court-ordered treatment. The social welfare and hospital care systems seem to provide care irrespective of case manager intervention. The study design, interventions and assessments instruments were well received by patients but needs to be replicated with a larger population. CLINICAL IMPLICATIONS: The 100% retention in the case management support group indicates that patients were satisfied with this type of intervention and the methodology seems to be useful in order to retain abstinence.

Intervention with feedback using Outcome Questionnaire 45 (OQ-45) in a Swedish psychiatric outpatient population. A randomized controlled trial.

AIM: The objective of the study was to evaluate the efficacy of the Outcome Questionnaire 45 (OQ-45) with feedback in a Swedish psychiatric outpatient population using a randomized controlled design. METHOD: In all 1720 patients made at least one regular visit to the clinics in the period 12 February 2007 to 10 February 2008 and received information about the study. Of these, 374 patients (22%) agreed to participate. After written consent, 188 patients were randomized to the feedback group and 186 patients to the control group. Those constituted the intention-to-treat (ITT) group. Two hundred and sixty-two patients (70%) completed the OQ-45 questionnaire at least twice, and they were included in the per-protocol analysis. Those who improved less than expected and were at risk for treatment failure were called alerted patients. RESULTS: There was a tendency that patients who received feedback improved more than the controls in OQ-45 total score. In the ITT analysis, the P-value was 0.061 and the effect size g = 0.21. In the per-protocol analysis the P-value was 0.076 and the effect size g = 0.24. In the intervention group, 27% of the patients were alerted because of risk of treatment failure vs. 28% in the control group (reaching level of alertness). The OQ-45 differences between the intervention and control groups did not significantly differ for patients who were alerted/reaching level of alertness and for non-alerted patients (g = 0.17 and g = 0.28, respectively). CONCLUSIONS: The feedback group had a tendency to improve more than the control group, possibly indicating that the method is effective, and the result (basically) supports previous findings.

Risk factors for criminal recidivism - a prospective follow-up study in prisoners with substance abuse.

BACKGROUND: Substance use in general has been shown to predict criminal recidivism. The present study aimed to examine potential predictors of criminal recidivism, including substance-specific substance use patterns, in prisoners with substance use. METHODS: A cohort of prisoners with substance use problems (N = 4,152) were assessed with the Addiction Severity Index (ASI) in the Swedish criminal justice system. Clients were followed for an average of 2.7 years. Criminal recidivism was defined as any return to the criminal justice system. RESULTS: During follow-up, 69 percent (n = 2,862) returned to the criminal justice system. Recidivism was associated with amphetamine and heroin use, with an additive risk for injectors, and with polysubstance use. Also, recidivism was negatively associated with alcohol, other opioids than heroin/methadone and with hallucinogenic drugs, and positively associated with previous psychiatric in-patient treatment, violent behaviour, and with a shorter index sentence. Associations remained when controlling for type of crime. CONCLUSIONS: Even when controlling for type and severity of crime, and for psychiatric problems, risk of criminal relapse was increased by substance use variables, including amphetamine, heroin and polysubstance use, and an additional risk was shown for injection drug users. These findings have implications for the need for substance abuse treatment after release from prison.

Respondent-driven sampling in a syringe exchange setting.

AIMS: Respondent-driven sampling is a research technique, new to the Scandinavian setting, used in hard-to-reach populations, such as subjects at risk for HIV, including drug users. This study aimed to evaluate the use of respondent-driven sampling originating from syringe exchange clients, as a method to identify 'hidden' drug users without treatment or social service contact. METHODS: Nine heroin and amphetamine injectors were recruited as 'seeds' and instructed to recruit up to three heavy drug users in a chain-referral process. Recruited clients were interviewed about drug use, social conditions and contacts with treatment, syringe exchange and other authorities. In order to estimate whether the recruitment managed to evolve into groups of 'hidden' drug users, clients included beyond the fourth wave of chain-referral were compared with seeds (wave 0) and clients recruited in waves 1-3. RESULTS: Five seeds were generative, and in total, 66 clients were assessed. Except for one of the 35 variables studied, clients in waves 4-9 did not differ from clients in waves 0-3, and were no less likely to have contacts with authorities. All clients except one were injectors and syringe exchangers, and clients recruited later in the chain-referral even tended to attend the syringe exchange more frequently. CONCLUSIONS: Respondent-driven sampling originating from syringe exchange clients may have difficulty reaching beyond the population of injectors and syringe exchangers. The technique, new to this geographical setting, has potential for future studies, but particular efforts may be necessary to study out-of-treatment heavy drug users unknown to the syringe exchange program.

Anabolic androgenic steroids in the general population: user characteristics and associations with substance use.

AIMS: To analyse correlates of anabolic androgenic steroids (AAS) use in the general male population. DESIGN: A national household survey. PARTICIPANTS: Individuals aged 15-64 years in Sweden. MEASUREMENTS: AAS use and potential correlates of AAS use, including demographic data, financial situation, physical training, and substance use. In hierarchical logistic regression analyses, lifetime users of AAS (n = 240) were compared to all nonusers (n = 13,920) and to nonusers who reported that they had been offered AAS (n = 487). RESULTS: AAS use was most strongly associated with a lifetime history of illicit drug use and the misuse of prescription drugs. When controlling for substance use, AAS was associated with physical training and lower education. Illicit drug use and misuse of prescription drugs separated AAS users from nonusers who had been offered AAS. No associations were seen with AUDIT scores for risk alcohol drinking. CONCLUSIONS: In this general population survey in men, lifetime use of AAS appears to share common characteristics with illicit substance use. Both substance use variables and physical training remained associated with AAS use when controlling for one another.

Repetition of suicide attempts across episodes of severe depression. Behavioural sensitisation found in suicide group but not in controls.

BACKGROUND: Those who die by suicide and suffer from depression are known to have made more suicide attempts during their life-span as compared to other people with depression. A behavioural sensitisation or kindling model has been proposed for suicidal behaviour, in accordance with a sensitisation model of depressive episodes. The aim of the present study was to test such a model by investigating the distribution of initial and repeated suicide attempts across the depressive episodes in suicides and controls with a unipolar severe depression. METHOD: A blind record evaluation was performed of 80 suicide victims and controls admitted to the Department of Psychiatry between 1956 and 1969 and monitored to 2010. The occurrence of initial and repeated suicide attempts by order of the depressive episodes was compared for suicides and controls. RESULTS: The risk of a first suicide attempt decreased throughout the later episodes of depression in both the suicide group (p < .000) and control group (p < .000). The frequencies of repetition early in the course were actually higher in the control group (p < .007). After that, the risk decreased in the control group, while the frequencies remained proportional in the suicide group. At the same time, there was a significantly greater decreased risk of repeated attempts during later episodes in the control group as compared to the suicide group (p < .000). The differences were found despite a similar number of episodes in suicides and controls. CONCLUSION: Repeated suicide attempts in the later episodes of depression appear to be a risk factor for suicide in severe depression. This finding is compatible with a behavioural sensitisation of attempts across the depressive episodes, which seemed to be independent of a corresponding kindling of depression.

Commitment to coercive care in relation to substance abuse reports to the social services. A 2-year follow-up.

BACKGROUND: In Sweden, a person with substance abuse can be reported to the social services for an investigation about commitment to coercive care. After a change in legislation, municipalities varied greatly in the ratio of commitments/reports compared with the period before the legislation was amended. AIMS: The primary aims of this study were first, to investigate whether subjects from municipalities with a high ratio of commitments/reports have a better outcome compared with subjects from municipalities with a low ratio and second, if a high ratio has an impact on mortality. METHODS: The study involved two municipalities with high ratio of commitments/reports with 56 cases reported for substance abuse including 31 committed cases (55%). It also included two municipalities with a low ratio, 50 reported cases including six committed cases (12%). Two social service inspectors at the country administrative board assessed the cases in terms of severity of addiction according to legal criteria (κ(s)=0.66), indicating good inter-rater agreement. A global index based on information about substance abuse, employment and housing was used as outcome measure at the 2-year follow-up. RESULTS: Global outcome did not differ between cases from high- and low-ratio municipalities. Seven subjects had deceased because of causes related to substance abuse. None of the deceased had been committed to coercive care. CONCLUSIONS AND CLINICAL IMPLICATIONS: In conclusion, the different ratios of commitments/reports did not influence global outcome. Commitment may reduce substance-related deaths.

Daily Automated Telephone Assessment and Intervention Improved 1-Month Outcome in Paroled Offenders.

This randomized trial evaluates whether automated telephony could be used to perform daily assessments in paroled offenders (N = 108) during their first 30 days after leaving prison. All subjects were called daily and answered assessment questions. Based on the content of their daily assessments, subjects in the intervention group received immediate feedback and a recommendation by automated telephony, and their probation officers also received a daily report by email. The outcome variables were analyzed using linear mixed models. The intervention group showed greater improvement than the control group in the summary scores (M = 9.6, 95% confidence interval [CI] = [0.5, 18.7], p = .038), in mental symptoms (M = 4.6, CI = [0.2, 9.0], p = .042), in alcohol drinking (M = 0.8, CI = [0.1, 1.4], p = .031), in drug use (M = 1.0, CI = [0.5, 1.6], p = .000), and in most stressful daily event (M = 1.9, CI = [1.1, 2.7], p = .000). In conclusion, automated telephony may be used to follow up and to give interventions, resulting in reduced stress and drug use, in paroled offenders.

Repetition and severity of suicide attempts across the life cycle: a comparison by age group between suicide victims and controls with severe depression.

BACKGROUND: Suicide attempts have been shown to be less common in older age groups, with repeated attempts generally being more common in younger age groups and severe attempts in older age groups. Consistently, most studies have shown an increased suicide risk after attempts in older age. However, little is known about the predictive value of age on repeated and severe suicide attempts for accomplished suicide. The aim of the present study was to investigate the reduced incidence for initial, repeated, or severe suicide attempts with age in suicide victims and controls by gender. METHODS: The records of 100 suicide victims and matched controls with severe depression admitted to the Department of Psychiatry, Lund University Hospital, Sweden between 1956 and 1969, were evaluated and the subjects were monitored up to 2006. The occurrence of suicide attempts (first, repeated, or severe, by age group) was analysed for suicide victims and controls, with gender taken into consideration. RESULTS: There was a reduced risk for an initial suicide attempt by older age in females (suicide victims and controls) and male controls (but not suicide victims). The risk for repeated suicide attempts appeared to be reduced in the older age groups in female controls as compared to female suicide victims. The risk for severe suicide attempts seemed reduced in the older age groups in female suicide victims. This risk was also reduced in male controls and in male controls compared to male suicide victims. CONCLUSION: In the older age groups repeated attempts appeared to be predictive for suicide in women and severe attempts predictive in men.

Number of addictive substances used related to increased risk of unnatural death: a combined medico-legal and case-record study.

BACKGROUND: Substance use disorders have repeatedly been found to lead to premature death, i.e. drug-related death by disease, fatal intoxications, or trauma (accidents, suicide, undetermined suicide, and homicide). The present study examined the relationship between multi-drug substance use and natural and unnatural death. METHODS: All consecutive, autopsied patients who had been in contact with the Addiction Centre in Malmö University Hospital from 1993 to 1997 inclusive were investigated. Drug abuse was investigated blindly in the case records and related to the cause of death in 387 subjects. RESULTS: Every substance apart from alcohol used previously in life added to the risk of unnatural death in a linear way. There were independent increased risks of fatal heroin overdoses or undetermined suicide. Death by suicide and violent death were unrelated to additional abuse. CONCLUSION: The number of drugs used was related to an increased risk of unnatural death by undetermined suicide (mainly fatal intoxications) and heroin overdose.

Do responsible beverage service programs reduce breath alcohol concentration among patrons: a five-month follow-up of a randomized controlled trial.

AIMS: To examine whether the decrease in the mean breath alcohol concentration (BrAC) and the rowdy social atmosphere reported after one month remained stable in the five-month assessment. DESIGN: Randomized controlled trial. SETTING: University bars. PARTICIPANTS: The five-month assessment was based on 596 students visiting student bars during ordinary pub evenings. INTERVENTION: Bartenders (n = 40) in 6 of 12 bars on a university campus underwent training programs in a randomized pattern. Bartenders in control bars did not participate in the program. MEASUREMENTS: The BrAC and reported social atmosphere in a five-month follow-up assessment. FINDINGS: All measurements (BrAC, rowdy, cozy, and high social atmosphere) showed that time had a significant decreasing effect. The positive effects on BrAC and rowdy atmosphere shown in the one-month follow-up were no longer evident after five months. CONCLUSION: The positive results after one month were not stable after five months. The study's limitations are noted.

From Substance Use Disorders in Life to Autopsy Findings: A Combined Case-Record and Medico-Legal Study.

Objectives: Several studies have shown mortality and suicide risk in substance use disorders, and autopsy findings with respect to the used substances. However, there seems to be a gap in the knowledge about substances misused in life and at death at the within-person level. Methods: All consecutive, autopsied patients during 1993 to 1997, who had been in contact with the Addiction Centre in Malmö from 1968, were investigated (365 subjects). Drug misuse in the long-term course noted in case records was related to autopsy findings. Self-inflicted death (suicide/undetermined suicide/accidental overdose) was compared with natural death. Results: Benzodiazepine misuse was associated with a high risk of autopsy findings of the substance in suicide and death of undetermined intent. It was also associated among non-misusers, but less so. An alcohol level above 1‰ was found more often in self-inflicted death. Prescription opioids at autopsy were mainly found in self-inflicted death among non-misusers. Heroin misuse was related to overdose. Central nervous system stimulants (CNS-S) and cannabis were rarely found in self-inflicted death among previous misusers. The overlap between depression in life and antidepressants at death was low. Conclusions: Benzodiazepines and alcohol seem to disinhibit suicidal tendencies. Suicide risk among users of cannabis and CNS-S may be related to other risk factors than acute use. Implications for suicide prevention are discussed.

World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Substance Use and Related Disorders, Part 1: Alcoholism.

These practice guidelines for the biological treatment of substance use disorders were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). The goal during the development of these guidelines was to review systematically all available evidence pertaining to the treatment of substance use disorders, and to reach a consensus on a series of practice recommendations that are clinically and scientifically meaningful based on the available evidence. These guidelines are intended for use by physicians evaluating and treating people with substance use disorders and are primarily concerned with the biological treatment of adults suffering from substance use disorders. The data used to develop these guidelines were extracted primarily from various national treatment guidelines for substance use disorders, as well as from meta-analyses, reviews and randomized clinical trials on the efficacy of pharmacological and other biological treatment interventions identified by a search of the MEDLINE database and Cochrane Library. The identified literature was evaluated with respect to the strength of evidence for its efficacy and then categorized into four levels of evidence (A-D). This first part of the guidelines covers the treatment of alcohol dependence; Part 2 will be devoted to the treatment of drug dependence.

Cross-cultural patterns in college student drinking and its consequences--a comparison between the USA and Sweden.

AIMS: The aim of the study was to compare alcohol use, consequences and common risk factors between American and Swedish college students. METHODS: A secondary comparative analysis from one American and two Swedish studies in college settings. RESULTS: Swedish freshmen report higher alcohol use than US freshmen students. Swedish residence hall students report higher alcohol use than US residence hall students, but lower than American fraternity/sorority members. US students were less likely to be drinkers. Controlling for age, country moderated the relationship between family history and harmful drinking scores for women (stronger in the USA), and between expectancies and harmful drinking scores for men (stronger in Sweden), though in both cases this represented a small effect and patterns were similar overall. CONCLUSIONS: Swedish students are at higher risk for alcohol use than US students, but similar patterns between aetiological predictors and outcomes in both countries suggest that research from the USA is generalizable to Swedish students and vice versa. More research is needed to better understand unique relationships associated with age and family history.
