'Before, we ended up in conflicts, now we can provide support'-Experiences of Community Reinforcement and Family Training (CRAFT) for parents of young adults with hazardous substance use.

BACKGROUND: The prevalence of hazardous substance use is highest in the age between 18 and 25, but few young adults enter treatment. Community Reinforcement and Family Training (CRAFT) is a support program for concerned significant others (CSOs) of individuals with diverse substance use disorders and is proven efficacious in promoting treatment entry. The aim of the current study was to investigate the experiences of CRAFT among parents of substance using young adults. METHODS: We used a qualitative design conducting semi-structured interviews with 10 parents of young adults (18-24 years) with hazardous substance use. The participants were recruited from a randomized controlled trial of the CRAFT program. The transcribed interviews were analyzed using thematic analysis. RESULTS: We divided the results into three overall domains-Reasons for entering the CRAFT program, Strengths of the CRAFT program and Limitations of the CRAFT program - with three to four themes under each domain. The parents appreciated the accessible support at a time when they needed it due to feelings of shock and powerlessness, and they described communication strategies together with positive reinforcement as the two most helpful CRAFT-sessions. Regarding limitations of CRAFT in the current population, the parents wanted more accessible support for the young adults when they were ready to enter treatment, and described difficulties to practice CRAFT-components due to changing life-circumstances and fear of aggravated health for their young adults. CONCLUSION: The results provide arguments for the health care system to implement support programs to parents of young adults with hazardous substance use. The results show that CRAFT is suitable for the current population, but with some possible additions due to changing circumstances that are common in the young adult developmental phase emerging adulthood. TRIAL REGISTRATION: The trial was pre-registered at isrctn.com, reference number ISRCTN12212515 date: November 7, 2018.

Quality-adjusted life years among people who inject drugs in a needle syringe program in Sweden.

PURPOSE: Needle syringe programs (NSP) significantly reduce risk behavior and HIV and hepatitis transmission in people who inject drugs (PWID). However, PWID are underrepresented in studies on health-related quality of life (HRQoL), representing a barrier to evaluate effects of public health and preventive measures related to injecting drug use. In this study, we investigate how well the two questionnaires EQ-5D-3L and SF-6D measure health in PWID. We also estimate HRQoL in the PWID population. METHOD: Data on demographics, injection drug use, HIV, hepatitis status, and self-reported HRQoL were collected from 550 PWID enrolled in the Stockholm NSP at enrollment and at 6-, 12-, and 24-month follow-up. Self-rated HRQoL was measured as QALY, using EQ-5D-3L and the SF-6D. Item response theory (IRT) was used to evaluate which of the two instruments that measure health most accurately in this population. Regression analysis was used to estimate population-specific QALYs. RESULTS: The IRT analysis showed that SF-6D was better suited to measure health in PWID. More specifically, SF-6D to a larger extent discriminated between persons regardless of their health status, while EQ-5D was more suitable to detect persons with poorer health. Self-rated HRQoL showed that average QALY was lower among PWID compared to the general Swedish population. However, a general increase in self-reported health was noted over time among participants. CONCLUSION: This study increase knowledge of what instruments are most suitable to measure health among PWID. This is of great importance when evaluating effects of public health and preventive measures in the PWID population.

'Ageing with an alcohol problem is not what I envision': reclaiming agency in shaping personal ageing trajectory and recovery from alcohol problems.

BACKGROUND: Eliciting and understanding older persons' descriptions of their resources for healthy ageing and the interaction of these resources with alcohol use and alcohol problems can facilitate health promotion. It can also inform clinicians when identifying areas of recovery capital that present risks and strength for older people seeking alcohol treatment. The objective of this study was to illuminate the experiences and perspectives of older persons on ageing, alcohol use, treatment, and recovery from alcohol problems, as well as their understanding of healthy ageing. METHODS: Eight men and two women, aged 61 to 73 years, with moderate drinking as a treatment goal and treated at an outpatient alcohol clinic in Sweden, participated in semi-structured audio-recorded virtual interviews. A qualitative content analysis examined the transcribed interviews. RESULTS: Three themes were identified: "Tipping the balance", "Staying behind a veil" and "Lifting the vail". First, participants understood healthy ageing as a personal and multidimensional process that involved actively expanding, maintaining or adjusting to the resources needed to lead an active and meaningful life while preserving autonomy, dignity and independence for as long as possible. Second, most participants viewed moderate alcohol use as a contributor to healthy ageing. They sought treatment when their drinking became unsustainable and an immediate threat to their healthy ageing resources. Stigma, ambivalence and a lack of treatment options, however, contributed to delayed treatment. Third, the participants responded to treatment approaches that elicited their concern, incorporated their expertise and treatment and life goals, appreciated their autonomy and agency, and considered them partners in goal setting and decision making. Reduced drinking helped participants regain their agency and improved their healthy ageing capital which in turn catalyzed continuing recovery. CONCLUSIONS: Older persons in non-abstinent recovery perceive healthy ageing and alcohol recovery as personal and interacting multidimensional processes involving their agency to improve biopsychosocial functioning. Treatment approaches that recognize older persons' desire for healthy ageing, incorporate their treatment goals and respect their autonomy are likely to be acceptable and effective.

Absence of interferon-λ 4 enhances spontaneous clearance of acute hepatitis C virus genotypes 1-3 infection.

OBJECTIVES: Absence of a functional interferon-λ 4 (IFN-λ4) gene (IFNL4) predicts spontaneous resolution of acute hepatitis C virus (HCV) infections in regions with a predominance of genotype 1, whereas variants of the inosine triphosphate pyrophosphatase (ITPase) gene (ITPA) entailing reduced activity associate with increased sustained virologic response rates following some therapeutic regimens. This study aimed at investigating the impact of IFNL4 on acute HCV genotype 2 or 3 infections, and whether ITPase activity influenced outcome. MATERIALS AND METHODS: Two hundred and seven people who injected drugs (PWID) with documented anti-HCV seroconversion, and 57 PWID with reinfection with HCV were analyzed regarding IFNL4 (rs368234815 and rs12979860) and ITPA (rs1127354 and rs7270101), and longitudinally followed regarding HCV RNA. RESULTS: The spontaneous clearance of HCV infection in anti-HCV seronegative PWID was enhanced when IFN-λ4 was absent (44% vs. 20% for IFNL4 TT/TTrs1368234815 and ΔGrs1368234815 respectively, p < .001; OR 3.2) across genotypes 1-3. The proportion lacking IFN-λ4 was further increased following resolution of repeated re-exposure to HCV (74% among re-infected participants who had cleared at least two documented HCV infections). ITPA genetic variants did not independently impact on the outcome, but among males lacking IFN-λ4, reduced ITPase activity markedly augmented the likelihood of resolution (65% vs. 29% for <100% and 100% ITPase activity, p = .006). CONCLUSIONS: Absence of IFN-λ4 entails an enhanced likelihood of spontaneous resolution both following primary acute infection and repeated re-exposure to HCV across genotypes 1-3. Among men lacking IFN-λ4, reduced ITPase activity improved outcome.

Treatment of alcohol dependence in Swedish primary care: perceptions among general practitioners.

OBJECTIVE: To describe general practitioners' (GPs) attitudes to the management of patients with alcohol dependence in primary care and current treatment routines and their view on a new treatment approach; internet-based Cognitive Behavioral Therapy (iCBT). DESIGN: A qualitative interview study with ten GPs participating in a randomized controlled trial. The interviews were analyzed using qualitative content analysis. SETTING: The participating GPs were recruited via purposeful sampling from primary care clinics in Stockholm. SUBJECTS: The GPs were participants in an RCT investigating if iCBT when added to treatment as usual (TAU) was more effective than TAU only when treating alcohol dependence in primary care. RESULTS: The GPs found alcohol important to discuss in many consultations and perceived most patients open to discuss their alcohol habits. Lack of training and treatment options were expressed as limiting factors when working with alcohol dependence. According to the respondents, routines for treating alcohol dependence were rare. CONCLUSION: GPs believed that iCBT might facilitate raising questions about alcohol use and thought iCBT may serve as an attractive treatment option to some patients. The iCBT program did not require GPs to acquire skills in behavioral treatment, which could make implementation more feasible.KEY POINTSAlcohol dependence is highly prevalent, has a large treatment gap and is relevant to discuss with patients in many consultations in primary care.This study is based on interviews with 10 GPs participating in a randomized controlled trial comparing internet-based Cognitive Behavioral Therapy (iCBT) for alcohol-dependent patients to treatment as usual.GPs viewed alcohol habits as important to discuss and they perceived most patients are open to discuss this.The access to iCBT seemed to increase GPs' willingness to ask questions about alcohol and was viewed as an attractive treatment for some patients.The iCBT program did not require GPs to acquire skills in behavioral treatment, which might be timesaving and make implementation more feasible.

Treating alcohol use disorders in primary care - a qualitative evaluation of a new innovation: the 15-method.

OBJECTIVE: This study aims to explore how the characteristics of an innovation, the 15-method, a stepped care model for treatment of alcohol use disorders in primary care was perceived. METHODS/DESIGN/SETTING/SUBJECT: General practitioners and heads of primary care units (n = 10) that delivered the 15-method in a randomized controlled trial participated in individual interviews at two occasions in Stockholm, Sweden. Data were analyzed with theoretical thematic analysis, using Diffusion of Innovation Theory. RESULTS: The participants described that offering the 15-method met a need among their patients. Participants were positive towards the training and the manual for the method. They mentioned a previous lack of routines to work with alcohol use disorders. The 15-method was described as easy to use. It would however be more feasible to implement in a team of different professions, rather than among general practitioners only. Priorities made by regional health care managers were described as important for the implementation, as well as financial incentives. A barrier to implementation was that alcohol screening was perceived as difficult. While the 15-method was perceived as effective in reducing the patients' alcohol use and cost effective, participants expressed uncertainty about the long-term effects. CONCLUSIONS: The 15-method provides structure for treatment of alcohol use disorders and is described by general practitioners and heads as a promising approach. Being able to offer treatment for alcohol dependence may increase the uptake of alcohol interventions in primary care.KEY POINTSLittle attention has been given to develop treatment models for alcohol use disorders that are adapted to primary care settings.This study describes how an innovation, the 15-method, a stepped care model for treatment of alcohol use disorders in primary care was perceived.The 15-method provides structure for treatment of alcohol use disorders in primary care and is described by general practitioners and heads as a promising approach.Being able to offer treatment for alcohol dependence may increase the uptake of alcohol interventions in primary care.

Psychometric properties of the short version of the children of alcoholics screening test (CAST-6) among Swedish adolescents.

AIMS: The Children of Alcoholics Screening Test (CAST-6) is a brief screening instrument developed to identify children with parents having problematic alcohol use. The aim of this study was to evaluate the psychometric properties of the CAST-6 among adolescents aged 15-18 years, and also to identify an optimal cut-off score for this age group. METHODS: A total of 3000 15 to18 year-olds were randomly selected from a register of postal addresses in Sweden. An invitation letter, including access information to the electronic questionnaire, was sent out by regular mail and 1450 adolescents responded with baseline data. Test-retest reliability within a 2-3-week period was calculated based on the 111 respondents who answered the same questionnaire twice. To determine an optimal cut-off score, a small treatment-seeking sample (n = 22) was recruited from a support group agency to be used as a reference group. RESULTS: The six items of the CAST-6 screening test loaded onto one latent factor with good internal consistency (alpha = 0.88), and excellent test-retest reliability (ICC = 0.93, 95% CI 0.90-0.95). The optimal cut-off score among adolescents was 2 points with a sensitivity of 55% and specificity of 79% (AUROC = 0.71, 95% CI 0.58-0.83). CONCLUSIONS: The CAST-6 has good to excellent psychometric properties among adolescents. The identified optimal cut-off score of 2 points should be treated with caution due to study limitations. The CAST-6 can be used in various settings to identify a vulnerable at-risk group of children and adolescents that may be in need of support.

Efficacy of an Internet-Based Community Reinforcement and Family Training Program to Increase Treatment Engagement for AUD and to Improve Psychiatric Health for CSOs: A Randomized Controlled Trial.

AIMS: Community Reinforcement Approach and Family Training (CRAFT) is a support program for concerned significant others (CSOs) to identified persons (IPs) with alcohol use disorders, with the purpose of engaging IPs to treatment and to improve CSO functioning. The purpose of the present study was to investigate the efficacy of an internet-based version of CRAFT (iCRAFT). METHODS: Randomized controlled trial comparing iCRAFT with a wait-list (WL) condition with a nation-wide uptake in Sweden. A total of 94 CSOs to a treatment refusing IP, who described the IP according to DSM-IV criteria for alcohol dependence or abuse, were included in the study. iCRAFT consisted of five weekly administered therapist-guided modules with the following content: (a) improve CSOs' own mental health, (b) improve the CSOs skills in asking the IP to seek treatment, (c) positive communication skills training, (d) contingency management of IP drinking behavior. Main outcome measure was IPs initiative to seek treatment measured at 24 weeks. Secondary outcomes were IP's daily alcohol consumption, CSOs mental health, quality of life and relational satisfaction. RESULTS: Of 94 participants, 15 CSOs reported IP treatment initiative during the study period. Of these, 10 belonged to the iCRAFT condition and five to the WL condition. The difference between conditions was nonsignificant, and the results were inconclusive. Participants in iCRAFT showed short-term improvements regarding depressive symptoms, quality of life and relational happiness. CONCLUSION: This study was unable to demonstrate substantial changes in the iCRAFT program regarding IP treatment seeking or CSO mental health.

A qualitative study of facilitators and barriers to participate in a needle exchange program for women who inject drugs.

BACKGROUND: Women who inject drugs (WWID) show higher levels of injecting risk behaviour compared to men, putting them at risk of contracting HIV and hepatitis C (HCV). Compared to men, WWID are also less present in harm reduction programs such as needle exchange programs (NEP). The aim of this study is to investigate reasons for, and barriers to, participation in NEP among WWID in Sweden, and to identify measures that could be taken to strengthen the program and increase participation among WWID. METHOD: In-depth interviews (IDIs) were conducted with 20 WWID who had participated in the Stockholm NEP for at least six months and was over 18 years old. IDIs were audio recorded and transcribed et verbatim. Qualitative content analysis was used to identify themes. RESULTS: The need for sterile injection equipment was identified as the main driver to join and remain in the NEP program. Continuous participation in the NEP was further driven by easy access to a multitude of health-related services. The most valued service was the sexual and reproductive health services (SRHR), allowing participants to access contraceptives, cervical cancer screening and sexually transmitted infections testing (STI-testing). NEP staffs' respectful treatment of participants further contributed to program participation. However, participants also expressed a number of concerns around NEP participation, which created barriers to joining. These included losing custody or visitation rights to children, male partner jealousy and violence, unwillingness to spend time in the waiting area and fear of receiving positive HIV/HCV test results. Practical barriers included limited opening hours and travel distance to the NEP. To strengthen the program, most participants requested additional SRHR services. Most participants also proposed some form of "women only" access to the NEP, to strengthen the feeling of the NEP as a safe space. CONCLUSION: This study identified factors that may increase uptake of NEP among WWID. Additional SRHR services and "women only" access are recommended to be implemented and evaluated as part of NEP. These findings may inform and improve the current scale-up of NEPs in Sweden to ensure equal access to services.

Hepatitis C virus (HCV) related liver fibrosis in people who inject drugs (PWID) at the Stockholm Needle Exchange - evaluated with liver elasticity.

Background and aims: Sharing of unsterile injection equipment among people who inject drugs (PWID) is the major transmission-route for hepatitis C (HCV). HCV is highly prevalent in PWID in the Stockholm needle exchange programme (NEP). The frequency of advanced liver fibrosis among the participants is, however, unknown. Methods: From December 2016 to April 2018, all participants with chronic hepatitis C infection (CHC) were offered liver fibrosis evaluation at the Stockholm NEP, including liver stiffness measurement (LSM), a medical history and expanded blood tests to evaluate APRI and FIB-4 scores. Results: A total of 2037 individuals were enrolled of whom 964 (47.3%) had CHC. LSM was performed in 203 (21.1%) of eligible participants of whom 85% had mild fibrosis (LSM ≤9.4 kPa) and 15% advanced fibrosis (LSM ≥9.5 kPa). APRI >1 and FIB-4 > 3.25 only identified 30% of participants with advanced fibrosis. However, all 31(100%) participants with advanced fibrosis were detected when APRI >1 was combined with an age of ≥40 years and an injection drug use (IDU) duration of ≥15 years. Conclusions: We found that the diagnostic work-up for advanced fibrosis can be simplified with this combination of easily available factors. This allows identification of PWID in need of immediate HCV treatment to prevent further disease progression. Furthermore, LSM can be avoided among PWID with mild fibrosis, identified by age <40 years combined with IDU duration of <15 years and APRI score <1. This strategy enhances the HCV care cascade where LSM is not easily available, and will thus facilitate HCV treatment initiation.

Psychometric Properties of the AUDIT, AUDIT-C, CRAFFT and ASSIST-Y among Swedish Adolescents.

BACKGROUND/AIMS: Not enough is known about the psychometric properties of screening instruments for problematic alcohol consumption among adolescents. The aim of the current study was to evaluate and compare the performance of the screening instruments: Alcohol Use Disorders Identification Test (AUDIT), AUDIT-C, CRAFFT, and the alcohol domain of Alcohol, Smoking and Substance Involvement Screening Test-Youth (ASSIST-Y) among adolescents and to suggest optimal cut-offs indicating problematic use. METHODS: Data was collected from a general population sample (n = 1,421) and a treatment-seeking sample (n = 59) using electronic versions of the instruments. RESULTS: The internal consistencies for the instruments were fair (alpha's AUDIT 0.74, AUDIT-C 0.75, CRAFFT 0.67, ASSIST-Y 0.62), and test-retest reliabilities were good to excellent (intraclass correlation coefficients AUDIT 0.86, AUDIT-C 0.93, CRAFFT 0.77, ASSIST-Y 0.63). The CRAFFT and ASSIST-Y demonstrated reasonable construct validities while factor solutions for AUDIT and AUDIT-C could not be determined. The optimal cut-off score was 2 for both CRAFFT and ASSIST-Y (61 and 73% sensitivities and 79 and 65% specificities, respectively), while sensitivity scores were poor for AUDIT and AUDIT-C. CONCLUSION: Based on the current sample, ASSIST-Y and the CRAFFT performed better than AUDIT and AUDIT-C. Health-care clinics working with adolescents should carefully consider their choice of screening instruments.

Incidence and spontaneous clearance of hepatitis C virus (HCV) in people who inject drugs at the Stockholm Needle Exchange-Importance for HCV elimination.

The major transmission route for hepatitis C virus (HCV) is through sharing of unsterile injection equipment among people who inject drugs (PWID). The WHO strategy for HCV elimination by 2030 proposes increased efforts to treat PWID populations that drive the HCV epidemic. Among participants in the Stockholm needle exchange programme (NEP), the HCV prevalence is 60%. We aimed to study HCV incidence, spontaneous HCV clearance rate, and predictors associated with new HCV infections and reinfections in NEP participants. All 2320 patients enrolled in the programme between 8 April 2013 and 23 September 2016 were tested for HCV at baseline, and responded to a questionnaire regarding sociodemographic data and injection risk behaviour. Tests for HCV were repeated at an interval of 3-6 months. The anti-HCV prevalence in the NEP participants at baseline was 77%, and the prevalence of HCV RNA was 57%. 24% of the anti-HCV positive were HCV RNA negative with a spontaneously cleared HCV infection. The overall HCV incidence rate was 22/100 PY. The HCV incidence rate in the HCV naive group was 26/100 PY, and in the spontaneously cleared group 19/100. Although there were no significant differences in becoming HCV infected between the two groups (31% vs 29%), the rate of spontaneous HCV clearance was significantly lower in the HCV naive group, 20% vs 44%, (P < 0.05). A high HCV incidence rate was noted among the PWID indicating that treatment needs to be scaled up in conjunction with harm reduction measures to achieve HCV elimination goals set by WHO. This includes high coverage needle exchange programmes and effective addiction treatment for substance users, including opiate substitution treatment.

Treatment for Alcohol Dependence in Primary Care Compared to Outpatient Specialist Treatment-A Randomized Controlled Trial.

AIM: To investigate if treatment for alcohol dependence in primary care is as effective as specialist addiction care. METHOD: Randomized controlled non-inferiority trial, between groups parallel design, not blinded. The non-inferiority limit was set to 50 grams of alcohol per week. About 288 adults fulfilling ICD-10 criteria for alcohol dependence were randomized to treatment in primary care (men n = 82, women n = 62) or specialist care (men n = 77, women n = 67). General practitioners at 12 primary care centers received 1-day training in a treatment manual for alcohol dependence. Primary outcome was change in weekly alcohol consumption at 6-months follow-up compared with baseline, as measured with timeline follow back. Secondary outcomes were heavy drinking days, severity of dependence, consequences of drinking, psychological health, quality of life, satisfaction with treatment and biomarkers. RESULTS: Intention-to-treat analysis (n = 228) was statistically inconclusive, and could not confirm non-inferiority for the primary outcome, since the high end of the confidence interval exceeded 50 grams (estimated mean weekly alcohol consumption was 30 grams higher in primary care compared with specialist care; 95% confidence interval -10.20; 69.72). However, treatment in specialist care was not significantly superior to primary care (P = 0.146). Subanalysis suggests that specialist care was superior to primary care only for patients with high severity of dependence. CONCLUSIONS: Treatment for alcohol dependence in primary care is a promising approach, especially for individuals with low to moderate dependence. This may be a way to broaden the base of treatment for alcohol dependence, reducing the current treatment gap.

Web-Based Self-Help for Problematic Alcohol Use: a Large Naturalistic Study.

PURPOSE: This observational study examined user characteristics, intervention use patterns, and variables associated with reductions in alcohol consumption for anonymous Internet help-seekers using a Web-based self-help program. METHOD: A Web-based cognitive behavioral therapy (CBT) program with eight modules delivered over 10 weeks was offered to participants with at least hazardous use of alcohol according to the Alcohol Use Disorders Identification Test (AUDIT) (n = 4165). At baseline and 10-week follow-up, participants completed the Timeline-followback (TLFB), AUDIT, Drug Use Disorders Identification Test (DUDIT), Hospital Anxiety and Depression Scale (HADS), EuroQol-5 dimension (EQ-5D), World Health Organization Quality of Life Scale-abbreviated version (WHOQOL-BREF), Readiness to Change Questionnaire (RCQ), and Readiness Ruler. Follow-up completers and non-completers were compared at baseline, and follow-up completer outcomes were reported. Predictors of change in drinking behavior were evaluated at follow-up. RESULTS: Registered users were 41.88 years old on average (SD = 12.36), and 52 % were women; the mean baseline number of drinks during the past week was 27.27 (SD = 17.92) with 62 % in the AUDIT category of probable dependence and only 7 % having low-risk consumption according to public health guidelines. At follow-up (n = 1043), 53 % showed a clinically significant change to a lower level of alcohol use (χ2 = 254.403, p < 0.001); the mean alcohol consumption fell (t = 22.841, p < 0.001) and the proportion with low-risk consumption rose to 40 %. Being male, scoring higher on baseline readiness, completing the program, and accessing other support predicted low-risk drinking and clinically significant change to a lower level of alcohol use at follow-up. CONCLUSION: A publicly available Web-based program for managing problematic alcohol use attracted users with considerable alcohol- and health-related problems, which were changed to lower severity for follow-up completers.

Varenicline for treatment of alcohol dependence: a randomized, placebo-controlled trial.

BACKGROUND: Alcohol dependence is a devastating illness affecting a large population, and new pharmacological treatments with good efficacy are greatly needed. One potential candidate is varenicline, a smoking cessation agent with partial agonist action at α4 ß2 nicotinic acetylcholine receptors. METHODS: A total of 160 subjects, 30 to 70 years of age, fulfilling DSM-IV criteria for alcohol dependence without any serious physical or mental disorders, were recruited through advertisement at 3 university clinics in Sweden during March 2009 to January 2011. After a 2-week placebo run-in period, subjects received 2 mg varenicline daily (titrated from 0.5 mg during first week) or placebo for 12 weeks in a double-blind manner. RESULTS: The primary outcome was the proportion of heavy drinking days, measured by self-reported alcohol consumption. Primary and secondary outcomes were calculated as a mean over the 10-week steady-state active treatment period. In the primary outcome analysis, no effect of varenicline over placebo was found (p = 0.73 for the intention to treat [ITT] and 0.92 for per protocol [PP]). Secondary outcome analysis found a significant reduction of specific alcohol marker phosphatidylethanol (PEth) in the blood in the varenicline group compared to placebo (p = 0.02 ITT). Craving (p = 0.048 PP) and Alcohol Use Disorders Identification Test (AUDIT) scores (p = 0.015 ITT) were also reduced in the active treatment group. PEth more strongly correlated with self-reported alcohol consumption than carbohydrate-deficient ttransferrin and γ-glutamyl transferase, and correlation coefficients were higher in the varenicline group than in the placebo group for all markers. CONCLUSIONS: Although the results of the main outcome of this study did not support an effect of varenicline in alcohol-dependent individuals, the secondary analyses of PEth, craving and AUDIT score support an effect of varenicline on alcohol consumption. The disclosure of a treatment effect and the lack of a clear placebo effect when using PEth as outcome variable, together with a nonsymmetric bias associated with self-reported data, strongly argue for using the specific biomarker PEth in studies of treatments of alcohol dependence.

Phosphatidylethanol is superior to carbohydrate-deficient transferrin and γ-glutamyltransferase as an alcohol marker and is a reliable estimate of alcohol consumption level.

BACKGROUND: In clinical practice as well as research situations, it is of great importance to get reliable information about a patient's alcohol consumption. The aim of the study was to investigate the correlation of alcohol biomarkers (phosphatidylethanol [PEth], carbohydrate-deficient transferrin [CDT], γ-glutamyltransferase, aspartate aminotransferase, and alanine aminotransferase) to retrospective as well as diary-based alcohol self-reports and to examine whether it is possible to correlate a biomarker result to a more precise level of alcohol consumption. METHODS: One hundred and sixty alcohol-dependent patients were included in a randomized, placebo-controlled clinical trial of pharmacotherapy for alcohol dependence, of which 115 (76 men and 39 women) completed the study. Retrospective alcohol consumption data were collected at baseline, and alcohol diaries were used during the study. Blood samples for determination of alcohol biomarkers were collected on 5 occasions during the study. RESULTS: PEth and CDT showed a better correlation with alcohol consumption documented in the diary (PEth rs = 0.56 and CDT rs = 0.35) than with retrospective consumption data (PEth rs = 0.23 and CDT rs = 0.22). An even higher correlation (rs = 0.63) was seen between the 2 alcohol biomarkers PEth and CDT. At all consumption levels, PEth had the highest sensitivity of all biomarkers studied. CONCLUSIONS: PEth was the biomarker with the best correlation to self-reported alcohol consumption. PEth was superior to CDT owing to its substantially higher sensitivity but also due to its closer correlation to self-report. PEth values can be translated into an approximate level of alcohol consumption and PEth appears to be a more reliable measure of alcohol consumption than self-reports.

Predictors of treatment outcome for individuals with alcohol use disorder with a goal of controlled drinking.

BACKGROUND: Research is lacking on predictors of outcome for the treatment of alcohol use disorder (AUD) with a goal of controlled drinking (CD). The aim of the study was to investigate one-year outcomes of an RCT, investigating Behavioral Self-Control Training (BSCT) and Motivational Enhancement Therapy (MET) and predictors of positive outcome for weekly alcohol consumption, CD and symptom reduction in AUD. METHODS: This study is based on secondary analyses from a randomized controlled trial including 250 individuals with AUD (52% men) recruited from three specialized addiction clinics in Stockholm, Sweden. Linear and logistic mixed regression models were used for outcomes at 52 weeks, and linear and logistic regression models for the predictor analyses. RESULTS: BSCT was superior to MET for the change between baseline to 52 weeks for the outcome of CD, defined as low-risk drinking below ten standard drinks per week for both genders (p = 0.048). A total of 57% of individuals in BSCT attained a level of CD, as opposed to 43% in MET. Females were significantly better in attaining low-risk drinking levels compared to men. The predictor for obtaining CD and reducing weekly alcohol consumption, was a lower baseline alcohol consumption. Predictors of symptom reduction in AUD were lower baseline level of AUD, and a lower self-rated impaired control over alcohol consumption. CONCLUSIONS: BSCT was superior to MET in obtaining CD levels, and women were superior to men for the same outcome. The study corroborated baseline consumption levels as an important predictor of outcome in CD treatments. The study contributes with important knowledge on key treatment targets, and knowledge to support and advice patients in planning for treatment with a goal of controlled drinking. TRIAL REGISTRATION: The original study was registered retrospectively at isrtcn.com (14539251).

Community Reinforcement and Family Training versus counselling for parents of treatment-refusing young adults with hazardous substance use: A randomized controlled trial.

BACKGROUND AND AIMS: Despite the high prevalence and negative effects of hazardous substance use, few young adults enter treatment. Community Reinforcement and Family Training (CRAFT), a support programme for concerned significant others of people with substance use disorders, has proved efficacious in promoting treatment entry. The aim of the current trial was to compare the efficacy of CRAFT with an active control for parents of young adults (aged 18-24 years) with hazardous substance use. DESIGN: This was a randomized controlled superiority trial comparing CRAFT (n = 58) with an active control group receiving manualized counselling (n = 55), with outcome assessments at 6, 12 and 24 weeks (primary end-point). A sequential design with a stopping rule was added post recruitment commencement. SETTING: The study took place in two outpatient clinics for young adults in Stockholm, Sweden, and subsequently via video-conference due to COVID-19. PARTICIPANTS: Between October 2018 and May 2021, 113 participants (92% female) who were parents of young adults (87% male) were recruited. Recruitment was discontinued when 70% of the planned sample had been recruited, following an interim analysis of the primary outcome showing no difference between conditions. INTERVENTION AND COMPARATOR: Participants were randomized (ratio 1 : 1) to eight manual-based individual CRAFT sessions or five individual manual-based counselling sessions + one voluntary psychoeducative group session, delivered over maximum 14 weeks. MEASUREMENTS: The primary outcome measure was the rate of young adult entry in substance use treatment during the trial period (24 weeks). FINDINGS: At the 24 weeks follow-up, 19 (33%) of CRAFT participants and 17 (31%) of counselling participants had reported young adult treatment entry, with no difference between conditions (odds ratio CRAFT versus counselling 0.84, 95% confidence interval = 0.35; 1.99, P = 0.700). Both conditions reported clinically relevant reductions in young adult substance use, but no change in participants' levels of depression, anxiety or stress. CONCLUSIONS: This trial showed no statistically significant evidence that Community Reinforcement and Family Training (CRAFT), a support programme for concerned significant others of people with substance use disorders, is more efficacious than manual-based counselling regarding treatment entry for young adults.

Behavioural self-control training versus motivational enhancement therapy for individuals with alcohol use disorder with a goal of controlled drinking: A randomized controlled trial.

BACKGROUND AND AIMS: Controlled drinking (CD) is an attractive treatment goal for a large proportion of individuals with alcohol use disorder (AUD), but the availability of treatment methods supporting a goal of CD is scarce. We tested if behavioural self-control training (BSCT) was superior to motivational enhancement therapy (MET) for individuals with AUD with a treatment goal of CD. DESIGN: Randomized controlled two-group trial. Follow-ups were conducted at 12 and 26 weeks (primary end-point) after inclusion. SETTING: Three specialized dependency care clinics in Stockholm, Sweden. PARTICIPANTS: Two hundred and fifty self-referred adults (52% men) fulfilling criteria of AUD (DSM-5) and a stated treatment goal of CD. INTERVENTION AND COMPARATOR: BSCT (n = 125), a five-session treatment based on cognitive behavioural therapy versus the active comparator, MET (n = 125), containing four sessions based on Motivational Interviewing. MEASUREMENTS: Primary outcome measure was mean weekly alcohol consumption at the 26-week follow-up, adjusted for baseline consumption. CONCLUSIONS: A randomized controlled trial found no evidence of a difference between behavioural self-control training and motivational enhancement therapy in reducing weekly alcohol consumption. Both groups substantially reduced consumption and behavioural self-control training was superior in reducing hazardous drinking.

A qualitative interview study of patient experiences of receiving motivational enhancement therapy in a Swedish addiction specialist treatment setting.

BACKGROUND: Motivational enhancement therapy (MET) has shown to be efficacious as treatment of alcohol use disorder (AUD), in reducing alcohol consumption and related consequences. However, qualitative research on how patients perceive this treatment is lacking. The aim of this study was to explore how patients experience MET as a treatment for AUD. METHODS: Fifteen patients (8/7 female/male) participated in semi-structured interviews after receiving MET at a specialized addiction outpatient clinic in Sweden. Data were analyzed by thematic analysis. RESULTS: Five themes were identified: the therapist conveyed the MI-spirit, the therapist did not guide on how to reach the goal, participants were committed to change before starting treatment, participants were uncertain if treatment was enough to maintain change, and significant others were not wanted in sessions. Participants appreciated the supportive relationship with their therapist, but some experienced therapy as overly positive, with no room to talk about failure. Further, they experienced a low level of guidance in goal-setting. For some, this was empowering, while others requested more direction and advice. Participants perceived their motivational process to have started before treatment. MET was considered to be too brief. None of the participants brought a significant other to a session. CONCLUSIONS: Therapist behaviors in line with MI spirit were emphasized as key to the development of a positive therapeutic relationship. More specific advice on goal-setting may be effective for supporting change in some patients. Longer treatment is requested among patients to support the patient's self-efficacy for change. Significant others can support change without necessarily being present in sessions. TRIAL REGISTRATION: The current trial was retrospectively registered at isrtcn.com (14539251).
