Problematic use of the Internet among adolescents has risen in the last decade. The Compulsive Internet Use Scale (CIUS) is one of the most frequently internationally-used tools developed to assess Problematic Internet Use (PIU). However, evidence concerning its validity and reliability in its Spanish version for the adolescent population is currently lacking. Thus, the main goal of the present study was to analyse the psychometric properties of CIUS scores in a large sample of Spanish adolescents. The sample consisted of 1,790 participants (53.7% female, mean age = 15.70 years old, SD = 1.26). The one-dimensional model displayed appropriate goodness of fit indices after error covariance of five items were allowed to correlate. Strong measurement invariance was found for the one-dimensional model across age and gender. The McDonald's Omega coefficient for the total score was 0.91. Furthermore, PIU was positively associated with different indicators of poor wellbeing and psychological difficulties and negatively associated with prosocial behaviour, self-esteem and sense of belonging to the educational centre. The study provided evidence of validity for the CIUS, confirming its utility for screening PIU in non-clinical adolescents.

In its action plan (2022-2030) to reduce the harmful use of alcohol, WHO calls on economic operators to "substitute, whenever possible, higher-alcohol products with no-alcohol and lower-alcohol products in their overall product portfolios, with the goal of decreasing the overall levels of alcohol consumption in populations and consumer groups". This paper investigates substitution within beer brands at the level of the consumer, based on Spanish household purchase data using interrupted time series analysis. For households (n = 1791, 9.1% of all households) that newly bought at least one of eleven branded zero-alcohol beers (responsible for over three-quarters of all zero-alcohol beer purchased), the associated purchases of all grams of alcohol after the first purchase of zero-alcohol beer were reduced by 5.5%, largely due to substituting every one litre of higher strength beer (ABV > 3.5%) with 0.75 litres of same-branded zero-alcohol beer (ABV = 0.0%). For households (n = 337, 1.8% of all households) that had never previously purchased a same-branded higher-strength beer, but newly purchasing a same-branded zero-alcohol beer, the associated purchases of all grams of alcohol after the first purchase of zero-alcohol beer were reduced by 14%; this reduction was largely due to such households' decreasing their associated purchases of wines and spirits. Thus, at the level of the consumer, based on Spanish household purchase data of branded zero-alcohol beers, the evidence behind WHO's call for substitution appears to be substantiated.

Substance use and abuse is a major public health problem. Research has generally shown that sexual minority groups such as lesbian, gay, bisexual, transgender and other (LGBT+) people are among the most at-risk vulnerable groups for substance use. However, research in the Spanish context is very scarce and has not analyzed these issues. This research, therefore, aimed to analyze substance use in young people according to their sexual orientation through two studies using representative samples of adolescents. The analyses revealed only some differences in substance use by sexual minority groups. Bisexual adolescents showed a higher frequency of use in some indicators of tobacco, cannabis and alcohol, and lesbians showed a higher frequency of heavy alcohol use but no other indicators of differential use. Questioning adolescents, on the other hand, had the lowest rates of use compared to the other groups on many indicators. Results derived from both studies could indicate, at least with these samples and indicators, that there is no generalized and more frequent use of substances by people of sexual minority groups, which could suggest the existence of a stereotype rather than a fact.

The school environment is of great relevance in the prevention of drug use in students because it is where they spend most of their time and, since education is compulsory until upper secondary school in Spain, interventions in this area can reach the majority of children up to that stage. The objective of this systematic review is to determine the level of efficacy of the school preventive programs that have been implemented in Spain. Following the PRISMA recommendations, a systematic literature search was carried out in the Web of Science, PubMed/MEDLINE, Embase, Scopus, and Cochrane Library databases. The search yielded 274 studies, of which 29 studies were selected. It was found that 48 drug addiction prevention programs have been implemented in Spanish school context, of which only 18 (37.5%) had an evaluation of their effectiveness following the criteria and standards of effective prevention. Conversely, the programs that were not evaluated are far from these standards in their design. It is concluded that there are two models of school prevention of drug addiction in Spain: a model that meets this description; and another model classified as "pseudo-prevention", since its design does not meet the standards of effective prevention nor has its preventive efficacy been demonstrated.

There are few cross-cultural studies utilizing longitudinal analysis to explore problematic internet use (PIU), and almost none among adults. The present follow-up study compared three waves across 12-month period every six months and observed the natural course and trajectory of PIU in a European multi-country sample of adults from 11 countries (Finland, Germany, Italy, Spain, France, Switzerland, Hungary, Poland, UK, Norway, Belgium). A total of 139 participants (45.5% females) provided data across all three waves with an average age of 26.14 years (SD = 5.92). There were longitudinal effects in PIU, with statistical differences between at-risk users compared to healthy users in Waves 1 and 2, and Waves 1 and 3. The analyses of variance showed a longitudinal effect of waves on the PIU symptoms. PIU was significantly affected by time and type of user, with those classed as at-risk having higher scores than healthy users, although PIU decreased over time. In addition, the type of PIU detected in adults contained mild addictive symptoms. In conclusion, this study demonstrated that PIU was generally low among European adult population and tended to decrease over the one-year period, what contrasts with adolescent population findings.

Given the causal impact of alcohol use on stroke, alcohol control policies should presumably reduce stroke mortality rates. This study aimed to test the impact of three major Lithuanian alcohol control policies implemented in 2008, 2017 and 2018 on sex- and stroke subtype-specific mortality rates, among individuals 15+ years-old. Joinpoint regression analyses were performed for each sex- and stroke subtype-specific group to identify timepoints corresponding with significant changes in mortality rate trends. To estimate the impact of each policy, interrupted time series analyses using a generalized additive mixed model were performed on monthly sex- and stroke subtype-specific age-standardized mortality rates from January 2001-December 2018. Significant average annual percent decreases were found for all sex- and stroke subtype-specific mortality rate trends. The alcohol control policies were most impactful on ischemic stroke mortality rates among women. The 2008 policy was followed by a positive level change of 4,498 ischemic stroke deaths per 100,000 women and a negative monthly slope change of -0.048 ischemic stroke deaths per 100,000 women. Both the 2017 and 2018 policy enactment timepoints coincided with a significant negative level change for ischemic stroke mortality rates among women, at -0.901 deaths and -1.431 deaths per 100,000 population, respectively. Hemorrhagic stroke mortality among men was not affected by any of the policies, and hemorrhagic stroke mortality among women and ischemic stroke mortality among men were only associated with the 2008 policy. Our study findings suggest that the impact of alcohol control policies on stroke mortality may vary by sex and subtype.

One of the factors that increase the likelihood of adolescents starting to exhibit and consolidate anti-social behavior is drug use, with a consistent pattern of consumption of different substance found in young offenders (Aebi, Bessler & Steinhausen, 2021). A cognitive-behavioral group treatment program inspired by the positive psychology approach was developed and applied to drug use in minors deprived of liberty (experimental group); the results were compared to those of a group of adolescents with the same type of drug use in the same center (active control group) at two points in time: during and after incarceration. The fall in the rate of problems associated with drug use after incarceration in the experimental group was statistically significant compared to the control group, and the effect size of the experimental condition was large (ῆ2 = 0.55), much higher than the control group (ῆ2 = 0.16). The treatment program has proven to be an effective tool for reducing problems associated with drug use and is especially effective in reducing alcohol and cannabis consumption.

The objective was to analyze the changes in cannabis use during lockdown considering sex, age, living situation and level of addiction. This descriptive and non-probabilistic study used a convenience sample of 208 participants with ages between 18-57 years (64.3% men; mean age = 31.39 years), that reported consuming cannabis. The frequency of distinct typologies of cannabis use was analyzed and the level of addiction with the Cannabis Abuse Screening Test (CAST). An online survey was used to collect the variables under study. A total of 25% consumers increased their spliff (marijuana mixed with tobacco) consumption, 11.9% increased their joint (marijuana cigarette) consumption and 11.8% increased their hashish spliff consumption. Men had higher levels of cannabis addiction, however, during lockdown they reduced their marijuana spliff consumption while both men and women increased their joint consumption. Marijuana spliff consumption showed a greater increase in the 25-29 age group, in those living with people other than relatives or a partner, alone, or with a partner and was reduced mainly in those living with parents or other relatives. The living alone 18-24 years old group, and the living with parents 35-44 years old group showed higher levels of cannabis addiction (CAST). The rate of dependent consumers who increased their marijuana spliff consumption (49%) doubled compared to consumers with no addiction and moderate addiction. Regarding joints, consumption was 1.5 times higher than for moderate addiction consumers and three times higher than those with no addiction. The risk of cannabis addiction increased in certain groups during lockdown.

The profits obtained by the gambling industry in Spain represent almost one point of GDP and the proportion of minors who have gambled has reached a quarter. This situation occurs despite the law regulating gambling, which included among its objectives the prevention of addictive behaviors, as well as the protection of minors and other vulnerable groups. Recently, an additional regulation was approved to control gambling advertising. Bearing in mind the new regulatory context, we analyze the relationship between advertising and gambling in adolescents and young adults, studying especially young people who have already gambled and minors. We conducted an empirical investigation with a sample of 2,181 adolescents and young adults who filled out a questionnaire on gambling and advertising. We found that the variables associated with advertising are significantly related to gambling behavior and that, in addition, this correlation occurs with greater magnitude in men. We obtained higher scores in advertising influence among those subjects who have ever gambled compared to those who have not, highlighting the importance of discouraging the arrival of new gamblers. Regarding minors, we found significant differences in the different variables of advertising influence compared to young adults. These findings point to the need to evaluate this influence considering the new habits and interests of minors today.
