Mind it! A mindfulness-based group psychotherapy for substance use disorders in adolescent inpatients.

Cannabis use disorder (CUD) is the most frequent reason for psychiatric inpatient substance use disorder (SUD) treatment among 15-19-year-olds in Germany. Despite effective treatment programs, relapse rates remain high. Thus, existing multi-component programs (TAU) need to be enhanced with SUD-specific elements. Mindfulness-based interventions (MBI) seem promising as they can positively influence SUD-related behaviors (e. g. craving). Given limited research in adolescents, this randomized controlled trial investigated the extent to which MBI-based group therapy (Mind it!) as an add-on treatment to TAU led to fewer cannabis use days after 6 months in 84 adolescent inpatients with CUD. Additionally, craving, severity of CUD, and changes in mindfulness were monitored (pre-, post-, and follow-up (FU) assessments). The results revealed a significant reduction in cannabis use days in both groups at 6-month FU (d = - 0.72 and = - 0.75). Although minor additional benefits of Mind it! were evident post-treatment, specifically reduction of craving and SUD severity, by the 6-month mark, TAU exhibited a more substantial decrease in SUD severity (d = 0.78), and reward craving (d = 0.28) compared to Mind it!. Regarding self-regulation skills (mindfulness), Mind it! demonstrated superiority over TAU after 6-month FU (d = 0.27). Therapists judged the MBI as feasible. (Serious) adverse events were unrelated to Mind it!. There was a systematic dropout among Mind it! participants. Primarily, the results emphasize the effectiveness of TAU in reducing cannabis use. MBI also seem feasible for youth, but results remain inconsistent and unstable over time. Importantly, enhanced adherence to reduce dropouts is needed.Trial registration: German Clinical Trials Register, DRKS00014041. Registered on 17 April 2018.

Problematic Consumption of Alcohol, Cannabis and Cigarettes­a German Nationwide Survey on Psychopathology, Stress, Mindfulness, and Quality of Life.

BACKGROUND: Even among minors, the use of psychotropic substances is widespread in Europe. Data on the use of tobacco, alcohol and cannabis are regularly reported in Germany, but data on problematic use are lacking. In the present study, established screening instruments were used to investigate the prevalence of problematic use of cigarettes, alcohol and cannabis among children and adolescents. METHODS: A survey that was designed to be representative was conducted across Germany in a sample of 4001 persons aged 12-17. The survey consisted of established screening instruments for problematic consumption patterns and related psychosocial aspects. Prevalences were estimated, and bivariate and multivariate associated characteristics were studied. RESULTS: Among 12- to 17-year-olds in Germany, the prevalence values (with 95% confidence intervals) of problematic use were: for cigarettes, 0.5% [0.3; 0.7]; for alcohol, 11.3% [10.3; 12.3]; and for cannabis, 0.5% [0.3; 0.7]. For the problematic use of cigarettes, alcohol and cannabis, there were both bivariate and multivariate statistically significant associations with greater psychopathology, lower mindfulness, and a lower quality of life. For example, greater psychopathology and stress experience were both associated with an increased risk of problematic cannabis use (odds ratios 1.21 [1.11; 1.31] and 1.59 [1.33; 1.88]). CONCLUSION: A comparison with the few available previous findings implies that problematic alcohol consumption has become more prevalent. There were both similarities and differences across the three substances studied with respect to patterns of problematic consumption, particularly in relation to the experience of stress.

The Impact of Video-Based Microinterventions on Attitudes Toward Mental Health and Help Seeking in Youth: Web-Based Randomized Controlled Trial.

BACKGROUND: Mental health (MH) problems in youth are prevalent, burdening, and frequently persistent. Despite the existence of effective treatment, the uptake of professional help is low, particularly due to attitudinal barriers. OBJECTIVE: This study evaluated the effectiveness and acceptability of 2 video-based microinterventions aimed at reducing barriers to MH treatment and increasing the likelihood of seeking professional help in young people. METHODS: This study was entirely web based and open access. The interventions addressed 5 MH problems: generalized anxiety disorder, depression, bulimia, nonsuicidal self-injury, and problematic alcohol use. Intervention 1 aimed to destigmatize and improve MH literacy, whereas intervention 2 aimed to induce positive outcome expectancies regarding professional help seeking. Of the 2435 participants who commenced the study, a final sample of 1394 (57.25%) participants aged 14 to 29 years with complete data and sufficient durations of stay on the video pages were randomized in a fully automated manner to 1 of the 5 MH problems and 1 of 3 conditions (control, intervention 1, and intervention 2) in a permuted block design. After the presentation of a video vignette, no further videos were shown to the control group, whereas a second, short intervention video was presented to the intervention 1 and 2 groups. Intervention effects on self-reported potential professional help seeking (primary outcome), stigma, and attitudes toward help seeking were examined using analyses of covariance across and within the 5 MH problems. Furthermore, we assessed video acceptability. RESULTS: No significant group effects on potential professional help seeking were found in the total sample (F2,1385=0.99; P=.37). However, the groups differed significantly with regard to stigma outcomes and the likelihood of seeking informal help (F2,1385=3.75; P=.02). Furthermore, separate analyses indicated substantial differences in intervention effects among the 5 MH problems. CONCLUSIONS: Interventions to promote help seeking for MH problems may require disorder-specific approaches. The study results can inform future research and public health campaigns addressing adolescents and young adults.

[Substance use and the usage of social media, computer games, and gambling among apprentices at vocational schools]. / Substanzkonsum und Nutzung von sozialen Medien, Computerspielen und Glücksspielen unter Auszubildenden an beruflichen Schulen.

BACKGROUND: The aim of the current study was to assess the prevalence of the (problematic) consumption of alcohol, tobacco, and cannabis as well as the (problematic) use of social media, e­products, computer games, and gambling among apprentices. METHOD: Cross-sectional survey of 4591 apprentices at 17 vocational schools from Bavaria, Schleswig-Holstein, and Hamburg. Data was collected using questionnaires between March 2021 and April 2022. The primary endpoints were the 30-day prevalence and the problematic consumption and usage behavior of the mentioned substances/behaviors using screening instruments. RESULTS: Among the assessed substances/behaviors, social media were used most frequently by the apprentices with a 30-day prevalence of 97.7%, followed by alcohol (64.3%) and computer games (55.8%). Cigarettes were consumed by 35.1%, e­products by 17.9%, and cannabis by 15.4% of the apprentices. Of the apprentices, 12.2% reported having gambled in the past 30 days. Rates of problematic use were 47.4% for alcohol, 18.0% for tobacco, 6.2% for e­products, and 1.6% for cannabis. Problematic use of social media was indicated by 45.0% of the apprentices, of gambling by 2.2%, and of computer games by 0.7%. DISCUSSION: These results suggest that apprentices constitute a risk group for problematic substance use, indicating increased need for intervention. In particular, secondary prevention efforts in the areas of alcohol and social media should be taken into consideration due to their widespread prevalence in the vocational school setting.

Prevalence of substance use disorders and associations with mindfulness, impulsive personality traits and psychopathological symptoms in a representative sample of adolescents in Germany.

Adolescence is a critical phase for the development of substance use disorders (SUDs). For Europe and Germany, there are limited data on problematic substance use from representative youth samples. Trait mindfulness is relevant in buffering against substance use-related problems and associated deficits in self-regulatory control. The objective of this study is to estimate 12-month prevalence rates for SUDs in a representative sample of adolescents in Germany and to examine associations with mindfulness and related factors such as stress, impulsivity, sensation seeking and symptoms of psychopathology. A sample of 4001 adolescents aged 12-18 years from Germany was surveyed based on DSM-IV diagnostic criteria for SUDs. Logistic regression analyses were used to examine associations with mindfulness-related variables. Criteria of at least one of the assessed SUDs were endorsed by 11.2% of the adolescents. Alcohol use disorders had the highest prevalence rate (10.1%) followed by cannabis use disorders (2.6%). For both substances, the criteria for abuse were met about twice as often as those for dependence. The prevalence of cigarette dependence was 1.7%, while the prevalence for e-cigarette dependence was only 0.1%. Prevalence rates were higher for male youth and increasing with age. SUD prevalence was also related to mindfulness, impulsivity and sensation seeking and externalizing symptoms of psychopathology. The statistically significant associations varied across different SUDs. SUDs appear highly prevalent among German adolescents. The results have public health implications with regard to treatment needs and prevention measures in the youth population in Germany.

Risky Sexual Behaviour and Sexual Victimization among Young People with Risky Substance Use in Europe-Perspectives from Belgium, Sweden, the Czech Republic, and Germany.

BACKGROUND: Research indicates that among the risks associated with young people's alcohol and illicit drug use are sexual risks. However, insights into co-occurrence of substance use and sexual risks in adolescent samples and possible differences across countries are limited. METHODS: A sample of 1449 adolescents from Belgium, Sweden, the Czech Republic, and Germany screened positive for risky alcohol/illicit drug use in a web-based intervention against alcohol and illicit drug use. They also reported incidents of sex while being drunk and/or high on drugs, condomless sex on these occasions, and sexualized touching and sexual victimization while being drunk or high on drugs. RESULTS: In the sample, 21.5% of the participants reported sexualized touching, 9.9% being victim to sexual assault, and 49.8% having had sex while being drunk and/or high on drugs; of the latter, 48.3% had condomless sex. Reports on having had sex while being drunk and/or high on drugs were associated with higher levels of past 30-day binge drinking. Being a victim of sexual assault was associated with past 30-day binge drinking only in young men. CONCLUSION: When devising preventive interventions against risky substance use in adolescents, an additional focus should be set on integrating steps against sexual risks.

Effects of an App-Based Mindfulness Intervention during Pregnancy on the Infant's Prenatal Androgen Exposure: A Randomized Controlled Pilot Trial.

Prenatal androgen exposure modulates the development of the brain, with lasting effects on its function and behavior over the infant's life span. Environmental factors during pregnancy, in particular maternal stress, have been shown to influence the androgen load of the unborn child. We here addressed the research gap on whether a mindfulness intervention or a pregnancy education administered to pregnant women more affects the androgen exposure of the unborn child (quantified by the proxies of second-to-fourth digit length ratio (2D:4D) and anogenital distance assessed one year after delivery and at delivery, respectively). Moreover, we tested the mindfulness intervention's effects on maternal perceived stress, anxiety, depressiveness, and mindfulness. Pregnant women (gestation weeks 8-14) were randomized to a 15-week app-based mindfulness-oriented intervention (N = 72) or a pregnancy education intervention (control condition; N = 74). The mindfulness-oriented group did not significantly differ from the pregnancy education group in infants' 2D:4D or anogenital distance (partial η2 ≤ 0.01) or in maternal stress, anxiety, depressiveness, or mindfulness. However, the descriptive results indicate that across pregnancy, stress and anxiety decreased and mindfulness increased in both groups. Overall, this study did not show that the mindfulness intervention (relative to the pregnancy education) reduced the prenatal androgen exposure of the unborn children or improved the maternal outcomes significantly.

Model-based reconstruction of whole organ growth dynamics reveals invariant patterns in leaf morphogenesis.

Plant organ morphogenesis spans several orders of magnitude in time and space. Because of limitations in live-imaging, analysing whole organ growth from initiation to mature stages typically rely on static data sampled from different timepoints and individuals. We introduce a new model-based strategy for dating organs and for reconstructing morphogenetic trajectories over unlimited time windows based on static data. Using this approach, we show that Arabidopsis thaliana leaves are initiated at regular 1-day intervals. Despite contrasted adult morphologies, leaves of different ranks exhibited shared growth dynamics, with linear gradations of growth parameters according to leaf rank. At the sub-organ scale, successive serrations from same or different leaves also followed shared growth dynamics, suggesting that global and local leaf growth patterns are decoupled. Analysing mutants leaves with altered morphology highlighted the decorrelation between adult shapes and morphogenetic trajectories, thus stressing the benefits of our approach in identifying determinants and critical timepoints during organ morphogenesis.

Effects of an App-Based Intervention Program to Reduce Substance Use, Gambling, and Digital Media Use in Adolescents and Young Adults: A Multicenter, Cluster-Randomized Controlled Trial in Vocational Schools in Germany.

Vocational students are a risk group for problematic substance use and addictive behaviors. The study aim was to evaluate the effects of an app-based intervention on tobacco, e-cigarettes, alcohol, and cannabis use as well as gambling and digital media-related behaviors in the vocational school setting. A total of 277 classes with 4591 students (mean age 19.2 years) were consecutively recruited and randomized into an intervention (IG) or waitlist control group (CG). Students from IG classes received access to an app, which encouraged a voluntary commitment to reduce or completely abstain from the use of a specific substance, gambling, or media-related habit for 2 weeks. Substance use, gambling, and digital media use were assessed before and after the intervention in both groups with a mean of 7.7 weeks between assessments. Multi-level logistic regression models were used to test group differences. Intention-to-treat-results indicated that students from IG classes had a significantly larger improvement on a general adverse health behavior measure compared to CG (OR = 1.24, p = 0.010). This difference was mainly due to a significantly higher reduction of students' social media use in the IG (OR = 1.31, p < 0.001). Results indicate that the app "Meine Zeit ohne" is feasible for the target group and seems to have a small but measurable impact on students' health behavior.

An app-based training for adolescents with problematic digital-media use and their parents (Res@t digital): protocol for a cluster-randomized clinical trial.

Background: Digital media-use disorders (DMUD) in adolescents are a rising phenomenon associated with psychological distress, comorbid mental disorders, and high burden on affected families. Since the ICD-11 introduced criteria for gaming disorder, these can now be transferred to describe additional DMUD associated with social media platforms and streaming services. Most evidence for effective treatments comes from cognitive-behavioral therapy (CBT). However, interventions based on theoretical models for adolescents and their parents are widely missing, leading to a significant clinical gap. Methods: Res@t digital (Resource-Strengthening Training for Adolescents with Problematic Digital-Media Use and their Parents) is the app-based translation of the first model-based digital intervention for adolescents with DMUD and their parents based on CBT. It comprises separate but content-related modules for adolescents (Res@t-A) and parents (Res@t-P), applying multimodal techniques. The effectiveness of Res@t will be evaluated within a multicenter cluster-randomized controlled evaluator-blinded pre-post follow-up trial with the waitlist control group (CG). In addition to the Res@t program in the intervention group, both groups will receive treatment as usual within primary child and adolescent psychiatric/psychotherapeutic healthcare. The primary outcome addresses DMUD symptom reduction after 10 weeks. Secondary outcomes are related to a reduction in psychological and family-related problems and an increase in parental self-efficacy. All outcomes will be assessed using standardized self-report measures. A total of 1,334 participating adolescent-parent dyads from a large clinical network throughout Germany are planned to be included in the primary analyses based on an intention-to-treat approach, applying linear mixed models. Discussion: Assuming superiority of Res@t over the control condition, the intervention has the potential to provide evidence-based treatment for a significant number of help-seeking families, supporting local healthcare structures and resources. It is a promising program for practicable implementation and flexible use in different settings. Clinical trial registration: https://drks.de, DRKS00031043.

Substance-Use Disorders in Children and Adolescents.

BACKGROUND: The most common substance use disorders in childhood and adolescence have to do with alcohol and cannabis. These disorders begin as early as puberty, are often accompanied by other mental disorders, and, if untreated, very frequently persist into adulthood. METHODS: This review is based on pertinent publications retrieved by a selective search in PubMed on substance use disorders in children and adolescents. RESULTS: Substance use disorders are among the commonest mental disorders in childhood and adolescence. In Germany, approximately 10% of adolescents have tried cannabis at least once. The prognosis is negatively affected by individual (bio-)psychological traits, mental comorbidities, laws that facilitate consumption, socioeconomic disadvantage, consuming peers, and parental substance use disorders. A timely diagnosis, motivation by the pediatrician, and referral to specialized child and adolescent psychiatric services helps assure that those affected receive appropriate treatment, with the goal of abstinence from the substance as well as improvement in emotional regulation, affectivity, and attention. According to studies from the English-speaking countries and considering all treatment forms, treatment is completed by approximately 60% to 65% of children and adolescents; 20% to 40% of these patients are abstinent six months after the end of treatment. No studies of this type have been carried out to date in Germany. CONCLUSION: As the results of treatment are generally poor, there is a major need for research on the treatment and care of children and adolescents with substance use disorders. In particular, the interfaces between outpatient and inpatient care need further improvement.

A cell wall-associated gene network shapes leaf boundary domains.

Boundary domains delimit and organize organ growth throughout plant development almost relentlessly, building plant architecture and morphogenesis. Boundary domains display reduced growth and orchestrate development of adjacent tissues in a non-cell-autonomous manner. How these two functions are achieved remains elusive despite the identification of several boundary-specific genes. Here, we show using morphometrics at the organ and cellular levels that leaf boundary domain development requires SPINDLY (SPY), an O-fucosyltransferase, to act as cell growth repressor. Furthermore, we show that SPY acts redundantly with the CUP-SHAPED COTYLEDON transcription factors (CUC2 and CUC3), which are major determinants of boundaries development. Accordingly, at the molecular level CUC2 and SPY repress a common set of genes involved in cell wall loosening, providing a molecular framework for the growth repression associated with boundary domains. Atomic force microscopy confirmed that young leaf boundary domain cells have stiffer cell walls than marginal outgrowth. This differential cell wall stiffness was reduced in spy mutant plants. Taken together, our data reveal a concealed CUC2 cell wall-associated gene network linking tissue patterning with cell growth and mechanics.

Effectiveness of an app-based intervention to reduce substance use, gambling, and digital media use in vocational school students: study protocol for a randomized controlled trial.

BACKGROUND: Substance-related and addictive disorders are among the most common mental disorders in adolescence and young adulthood. Vocational school students are a risk group for problematic substance use and addictive behavior. However, the availability of evidence-based prevention concepts and programs is underdeveloped in the vocational school setting. METHODS/DESIGN: A two-arm cluster randomized waitlist-controlled trial will be conducted to evaluate the effectiveness of an app-based intervention to decrease substance use, gambling, and digital media use in vocational school students in Germany. Vocational students will participate in an app-based intervention that is designed to support voluntary commitment to abstain from or reduce substance or digital media use over a period of 2 weeks. The "education-as-usual" control arm will have access to the intervention after data collection is completed. One of the primary outcome measures will be the use of alcohol, nicotine, and digital media 30 days after the intervention. Several secondary outcome measures will also be included, such as cannabis consumption, gambling, symptoms of stress, physical activity, mindfulness, well-being, impulsivity and sensation seeking, and readiness to change. A total of 4500 vocational students from 225 classes will be recruited and randomized across three German federal states. DISCUSSION: This study protocol describes the design of an RCT testing the effectiveness of an app-based intervention to reduce addictive behaviors in vocational school students. It is expected that this approach will be feasible for and effective in the vocational school setting and that the study provides comprehensive information on the key factors involved in temporary abstaining or reducing substance or digital media use.

[Substance-related disorders and transition psychiatry]. / Substanzbezogene Störungen und Transitionspsychiatrie.

BACKGROUND: Addictive disorders are typically manifested during adolescence and have a high transmission rate into adulthood. When adulthood is reached the responsibility by the child and adolescent psychiatric care system ends and patients transition to adult psychiatry. A lack of supportive concepts and approaches to this transition can have detrimental effects on the long-term health of affected individuals. OBJECTIVE: Addiction treatment requirements of young adults transitioning between the systems of care are presented. Developmental psychopathological concepts are presented and treatment recommendations are provided. MATERIAL AND METHODS: The scientific literature on development-related approaches to addiction treatment was evaluated. Care conditions relevant to transitional psychiatry are discussed and a description of needs is carried out. RESULTS: Adolescents and young adults are very frequently affected by addictive disorders. The need for disorder-specific and age-specific transition-related concepts and services for these patients is high. During the transition from child and adolescent psychiatry to the psychiatric care system for adults, patients with substance-related disorders require treatment-related educational and age-appropriate psychosocial support services that address the high comorbidity and developmental delays. CONCLUSION: Age-specific and disorder-specific treatment services should be broadly expanded and the interfaces to youth welfare, addiction counseling and adult psychiatry should be better coordinated.

[Use of Electronic Cigarettes (e-cigs) and e-Shishas by Children and Adolescents: Evidence Paper of the Joint Addiction Commission of the German Societies and Professional Associations of Child and Adolescent Psychiatry and Psychotherapy]. / Nutzung elektronischer Zigaretten (E-Zigaretten) und E-Shishas durch Kinder und Jugendliche.

Use of Electronic Cigarettes (e-cigs) and e-Shishas by Children and Adolescents: Evidence Paper of the Joint Addiction Commission of the German Societies and Professional Associations of Child and Adolescent Psychiatry and Psychotherapy Abstract. The particular risks associated with the consumption of electronic cigarettes (e-cigs) in children and adolescents are not sufficiently considered in the health policy discourse. The present article evaluates the current dissemination and consumption patterns of e-cigarettes as well as the health risks attached to children and adolescents. Based on data from current national and international studies, there has been a clear increase in the consumption of e-cigarettes over the past years. This stands in sharp contrast to the overall decline in tobacco consumption among both children and adolescents in Germany. Young people without tobacco experience are now consuming more frequently e-cigarettes than those who occasionally or regularly use tobacco. They also are experimenting more frequently with conventional cigarettes if they have previously consumed e-cigarettes. The largely unregulated availability of e-cigarette products to the newest generation, such as JUUL, led to a dramatic increase in their prevalence among high-school students in the USA. Products with high nicotine content and multiple flavors are being marketed intensively as trendy lifestyle products to young user groups via advertising and social media campaigns. These products are also becoming increasingly relevant in Germany. The success of tobacco prevention in recent years is presently jeopardized by the ongoing effective advertising for e-cigarettes. The Addiction Commission of the German Child and Youth Psychiatric Federations and Scientific Societies therefore call for an immediate, strict, and comprehensive ban of e-cigarette advertising.

Strigolactones (SLs) modulate the plastochron by regulating KLUH (KLU) transcript abundance in Arabidopsis.

The timing of leaf emergence at the shoot apical meristem, or plastochron, is highly regulated in plants. Among the genes known to regulate the plastochron in Arabidopsis (Arabidopsis thaliana), KLUH (KLU), orthologous to the rice (Oryza sativa) PLASTOCHRON1, encodes the cytochrome P450 CYP78A5, and is thought to act through generation of a still unknown mobile signal. As klu mutants display not only a short plastochron but also a branching phenotype reminiscent of strigolactone (SL) mutants, we investigated whether KLU/CYP78A5 is involved in SL biosynthesis. We combined a genetic approach, a parasitic plant seed germination bioassay to test klu root exudates, and analysis of transcript abundances of SL-biosynthesis genes in the Arabidopsis klu mutants. We demonstrate that KLU is not involved in the SL-biosynthesis pathway. Moreover, this work allowed us to uncover a new role for SL during Arabidopsis development in modulating plastochron via a KLU-dependent pathway. Globally our data reveal that KLU is required for plastochron-specific SL responses, a first indication of crosstalk between SL and the KLU-derived signal.

Risk factors for prospective increase in psychological stress during COVID-19 lockdown in a representative sample of adolescents and their parents.

BACKGROUND: COVID-19 lockdown measures imposed extensive restrictions to public life. Previous studies suggest significant negative psychological consequences, but lack longitudinal data on population-based samples. AIMS: We aimed to prospectively identify increased psychological stress and associated risk factors in parent-child dyads. METHOD: We conducted a prospective, observational online study on a representative German sample of 1221 adolescents aged 10-17 years and their parents. Psychological stress and psychosocial variables were assessed before the pandemic (baseline) and 1 month after the start of lockdown (follow-up), using standardised measures. We used multilevel modelling to estimate changes in psychological stress, and logistic regression to determine demographic and psychosocial risk factors for increased psychological stress. RESULTS: The time of measurement explained 43% of the psychological stress variance. Of 731 dyads with complete data, 252 adolescents (34.5%, 95% CI 31.0-37.9) and 217 parents (29.7%, 95% CI 26.4-33.0) reported a significant increase in psychological stress. Baseline levels were lower than in dyads without increased psychological stress. Risk factors for increased psychological stress included sociodemographic (e.g. female parents, severe financial worries) and emotion regulation aspects (e.g. non-acceptance of emotional responses in parents, limited access to emotion regulation strategies in adolescents), explaining 31% of the adolescent (Nagelkerke R2 = 0.31) and 29% of the parental (Nagelkerke R2 = 0.29) model variance. CONCLUSIONS: This study is the first to prospectively show an increase in psychological stress during COVID-19 lockdown in a representative family sample. Identified demographic and psychosocial risk factors lead to relevant implications for prevention measures regarding this important public health issue.

[Disorders due to substance use or addictive behaviours in the ICD-11]. / Störungen durch Substanzgebrauch und abhängige Verhaltensweisen in der ICD-11.

Disorders due to substance use or addictive behaviours in the ICD-11 Abstract. This paper concerns the revised classification of Substance-Related and Addictive Disorders in the 11th edition of the International Classification of Diseases (ICD-11) of the World Health Organization. The revision of the ICD serves to reflect changes in the understanding and diagnosis of addictive disorders and the need to improve clinical applicability. Regarding substance-related and non-substance-related addictive disorders, considerable innovations were introduced compared to the previous version. Major innovations include an expanded range of substance classes, significant adjustments (i. e., simplifications) in the conceptual and diagnostic guidelines of substance-related disorders, particularly "substance dependence", the introduction of the category of "addictive behaviour," and, associated with this, the assignment of "gambling disorder" to the addictive disorders, and the inclusion of the new (screen-related) "gaming disorder." In addition, for the first time the ICD catalogue includes an expansion of diagnostic options for early, preclinical phenotypes of addiction disorders ("Episodic Harmful Use"). This article summarizes the changes in the field of addiction disorders and discusses them from a child and adolescent psychiatric perspective.

[Mindfulness in Development-oriented Approaches to Substance Use Prevention and Therapy: Rationale, Design and Objectives of the Research Consortium IMAC-Mind]. / Achtsamkeit in der entwicklungsorientierten Suchtprävention und -therapie: Rational, Design und Ziele des Forschungsverbundes IMAC-Mind.

Mindfulness in Development-oriented Approaches to Substance Use Prevention and Therapy: Rationale, Design and Objectives of the Research Consortium IMAC-Mind Substance use disorders (SUD) are a major contributor to morbidity and mortality. They are typically initiated during adolescence and can have fatal implications for healthy development. Despite substantial scientific advances, there remains a need to prioritize research directed at reducing risks for SUD, particularly in vulnerable periods and populations from a developmental perspective. Research indicates that reward sensitivity, impulsivity, deficient self-regulation, and stress reactivity develop markedly in childhood and adolescence and play an important role in the initiation and maintenance of SUD. A growing number of research results suggest that these factors can be favorably influenced by mindfulness-based interventions and that mindfulness-based exercises can be successfully integrated into established prevention and treatment programs. In this paper we summarize the conceptual relationships between the development and maintenance of addiction disorders and mindfulness, discuss existing empirical findings with regard to childhood and adolescence, and present the aims, study designs and intervention models of the subprojects from the ongoing research network "IMAC-Mind: Improving Mental Health and Reducing Addiction in Childhood and Adolescence through Mindfulness: Mechanisms, Prevention and Treatment".
