- Background and Aims: The prevalence of cannabis use based on self-reports is likely to be underestimated in population surveys, especially in contexts where its use is a criminal offence. Indirect survey methods ask sensitive questions ensuring that answers cannot be identified with an individual respondent, therefore potentially resulting in more reliable estimates. We aimed to measure whether the indirect survey method ‘randomized response technique’ (RRT) increased response rate and/or increased disclosure of cannabis use among young adults compared with a traditional survey.Design: We conducted two parallel nation-wide surveys during the spring and the summer of 2021. The first survey was a traditional questionnaire-based one (focusing on substance use and gambling). The second survey applied an indirect survey method known as ‘the cross-wise model’ to questions related to cannabis use. The two surveys employed identical procedures (e.g. invitations, reminders and wording of the questions)Setting and Participants: The participants were young adults (aged 18–29 years) living in Sweden. The traditional survey had 1200 respondents (56.9% women) and the indirect survey had 2951 respondents (53.6% women).Measurements: In both surveys, cannabis use was assessed according to three time-frames: life-time use; use during the past year; and use during the past 30 days.Findings: The estimated prevalence of cannabis use was two- to threefold higher on all measures when estimated using the indirect survey method compared with the traditional survey: use during life-time (43.2 versus 27.3%); during the past year (19.2 versus 10.4%); and during the past 30 days (13.2 versus 3.7%). The discrepancy was larger among males and individuals with an education shorter than 10 years, who were unemployed, and who were born in non-European countries.Conclusions: Indirect survey methods may provide more accurate estimates than traditional surveys on prevalence of self-reported cannabis use.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: This article summarizes the findings and conclusions of the third edition of Alcohol: No Ordinary Commodity. The latest revision of this book is part of a series of monographs designed to provide a critical review of the scientific evidence related to alcohol control policy from a public health perspective.Design: A narrative summary of the contents of the book according to five major issues.Findings: An extensive amount of epidemiological evidence shows that alcohol is a major contributor to the global burden of disease, disability and death in high-, middle- and low-income countries. Trends in alcohol products and marketing are described, indicating that a large part of the global industry has been consolidated into a small number of transnational corporations that are expanding their operations in Asia, Africa and Latin America. The main part of the book is devoted to a review of strategies and interventions designed to prevent or minimize alcohol-related harm. Overall, the most effective strategies to protect public health are taxation that decreases affordability and restrictions on the physical availability of alcohol. A total ban on alcohol marketing is also an effective strategy to reduce consumption. In addition, drink-driving counter-measures, brief interventions with at-risk drinkers and treatment of drinkers with alcohol dependence are effective in preventing harm in high-risk contexts and groups of hazardous drinkers.Conclusion: Alcohol policy is often the product of competing interests, values and ideologies, with the evidence suggesting that the conflicting interests between profit and health mean that working in partnership with the alcohol industry is likely to lead to ineffective policy. Opportunities for implementation of evidence-based alcohol policies that better serve the public good are clearer than ever before as a result of accumulating knowledge on which strategies work best.

- Background and Aims The global growth of mobile phone use has led to new opportunities for health interventions, including through text messaging. We aimed to estimate the effects of text messaging interventions on alcohol consumption among risky drinkers. Methods Systematic review and meta-analysis of reports on randomized controlled trials (RCTs) published in English. Searches were conducted on 23 May 2019 in PubMed; PubMed Central; CENTRAL; CDSR; DARE; NHS-EED; Scopus; PsycINFO; PsycARTICLES; CINAHL; and Web of Science. Measurements included number of episodes of heavy drinking (HED) per month and weekly alcohol consumption (WAC) in grams. Trials among risky drinkers who were not receiving co-interventions were included in the review (n = 3481, mean age 29 years, 41% female). Data were extracted from reports and authors were contacted for additional data. Results Ten trials were included and all analyses were based on random-effects models. Primary analyses, including seven trials (n = 2528) for HED and five trials (n = 2236) for WAC, found that the interventions may reduce self-reported HED [-0.33 episodes per month; 95% confidence interval (CI) = -0.79, 0.12] and WAC (-18.62 g per week; 95% CI = -39.61, 2.38), although both estimates included the null. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) quality of evidence was judged to be low for both HED and WAC, primarily due to risk of attrition and performance bias, heterogeneity and influence of pilot trials on estimates. Conclusions Text messaging alcohol interventions may reduce alcohol consumption compared with no or basic health information; however, there are doubts about the overall quality of the evidence.

- Background and aims Although an individual's childhood adversity is predictive of later substance misuse, the effect of adversity within an individual's friendship network has not been established. The current study aims to estimate the strength of the association between exposure to childhood adversity among individuals' friends at the onset of adolescence, relative to individuals' own exposure to childhood adversity, and hospitalization for substance misuse between young adulthood and retirement. Design Prospective cohort study. Setting Stockholm, Sweden. Participants Individuals born in 1953, living in Stockholm in 1963, and who nominated three best friends in the 6th grade school class (n = 7180; females = 3709, males = 3471), followed to 2016. Measurements The outcome was hospitalization with a main or secondary diagnosis attributed to substance misuse, reflected in Swedish inpatient records (ages 19-63 years). Five indicators of childhood adversity (ages 0-12 years) were operationalized into composite measures for individuals and their friends, respectively. Friendships were identified using sociometric data collected in the school class setting (age 13 years). Findings Individuals' own childhood adversity does not predict childhood adversity among friends (P > 0.05). Childhood adversity among friends is independently associated with an increased risk of an individual's later substance misuse [hazard ratio (HR) = 1.17, 95% confidence interval (CI) = 1.09-1.24], independently of an individual's own childhood adversity (HR = 1.47, 95% CI = 1.34-1.61). However, childhood adversity among friends does not moderate the association between individuals' own childhood adversity and later substance misuse. Conclusions Within a birth cohort of individuals born in 1950s Stockholm, Sweden, childhood adversity among an individual's friends appears to predict the individual's substance misuse in later life independently of an individual's own exposure to childhood adversity.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Treatment-resistant depression (TRD), defined as inadequate treatment response after at least two adequate treatment trials, is common among patients initiating antidepressant treatment. Current or previous substance use disorders (SUD) are common among patients with depression and often lead to worse treatment outcomes. However, in clinical studies, SUD have not been found to increase the risk for TRD. The aim of this study was to investigate the association between SUD and TRD.Design: Nested case-control study.Setting: Nation-wide governmental health-care registers in Sweden.Cases and controls: Data on prescribed drugs and diagnoses from specialized health care were used to establish a prospectively followed cohort of antidepressant initiators with depression (n = 121 669) from 2006 to 2014. Of these, 15 631 patients (13%) were defined as TRD cases, with at least three treatment trials within a single depressive episode. Each case with TRD was matched on socio-demographic data with five controls with depression.Measurements: Crude and adjusted odds ratios (aOR) with 95% confidence intervals (CI) estimated the association between TRD and SUD diagnosis and/or treatment in five different time intervals until the time for fulfillment of TRD definition for the case. The analysis was adjusted for clinical and socio-demographic covariates.Findings: Having any SUD during, or <= 180 days before start of, antidepressant treatment was associated with almost double the risk for TRD [<= 180 days before: adjusted OR (aOR) = 1.86, CI = 1.70-2.05]. Increased risks for TRD were found <= 180 days before treatment start for the subcategories of sedative use (aOR = 2.37; 1.88-2.99), opioids (aOR = 2.02; 1.48-2.75), alcohol (aOR = 1.77; CI = 1.59-1.98) and combined substance use (aOR = 2.31; 1.87-2.99).Conclusions: Recent or current substance use disorders is positively associated with treatment resistance among patients initiating treatment for depression.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Survey questions on usual quantity and frequency of alcohol consumption are regularly used in screening tools to identify drinkers requiring intervention. The aim of this study was to measure age-based differences in quantity and frequency of alcohol consumption on the Alcohol Use Disorders Identification Test (AUDIT) and how this relates to the prediction of harmful or dependent drinking.Design: Cross-sectional survey.Setting: Australia.Participants: Data were taken from 17 399 respondents who reported any alcohol consumption in the last year and were aged 18 and over from the 2016 National Drug Strategy Household Survey, a broadly representative cross-sectional survey on substance use.Measurement: Respondents were asked about their frequency of consumption, usual quantity per occasion and the other items of the AUDIT.Findings: In older drinkers, quantity per occasion [β = 0.53, 95% confidence interval (CI) = 0.43, 0.64 in 43–47-year-olds as an example] was a stronger predictor of dependence than frequency per occasion (β = 0.24, 95% CI = 0.17, 0.31). In younger drinkers the reverse was true, with frequency a stronger predictor (β = 0.54, 95% CI = 0.39, 0.69 in 23–27-year-olds) than quantity (β = 0.26, 95% CI = 0.18, 0.34 in 23–27-year-olds). Frequency of consumption was not a significant predictor of dependence in respondents aged 73 years and over (β = −0.03, 95% CI = −0.08, 0.02). Similar patterns were found when predicting harmful drinking. Despite this, as frequency of consumption increased steadily with age, the question on frequency was responsible for at least 65% of AUDIT scores in drinkers aged 53 years and over.Conclusions: In younger drinkers, frequent drinking is more strongly linked to dependence and harmful drinking subscale scores on the Alcohol Use Disorders Identification Test (AUDIT) than quantity per occasion, yet quantity per occasion has a stronger influence on the overall AUDIT score in this group. In older drinkers, frequency of consumption is not always a significant predictor of the AUDIT dependence subscale and is a weak predictor of the harmful drinking subscale.
