Background: With the increasing availability of digital media, the prevalence of problematic digital media use (PDMU) has risen, with children and adolescents being particularly affected. Mindfulness is discussed in relation to PDMU as a protective factor and as a key mechanism underlying mindfulness-based interventions (MBI’s). Given the high prevalence rates and the lack of age-specific research, this review provides an overview of studies examining the role of mindfulness and MBI’s in the context of PDMU in children and adolescents. Methods: Systematic literature search in four databases (PubMed, Embase, Cochrane, and Web of Science). Identified studies were independently screened by two authors. Results: Of the 93 articles identified, 16 studies were included in the review. The findings can be summarized into four main points: (1) mindfulness is negatively associated with PDMU; (2) mindfulness may attenuate the effects of risk factors on PDMU; (3) mindfulness is part of mediation models involving direct and indirect associations with PDMU and other outcomes; and (4) MBI’s show promise for reducing media-related symptoms. Conclusion: Despite the high need for preventive approaches, there is a lack of studies specifically targeting PDMU in children and adolescents. The current evidence on MBI’s is limited but promising. Future research should develop age-appropriate adaptations and systematically evaluate their effectiveness.

Online therapies have the potential to improve access to psychological services for individuals in need while alleviating the burden on healthcare systems. However, child and adolescent psychiatrists and psychotherapists (CAPPs) rarely integrate these services into their daily practice. This exploratory study investigates CAPPs’ acceptance of online therapy, with a focus on treating children and adolescents with digital media use disorders (DMUD). The study aimed to examine attitudes toward online therapy for DMUD treatment and to identify barriers and facilitating factors to its implementation. A cross-sectional online survey (5–10 min) was distributed to 1000 members of a German practitioner network, with 142 respondents completing it in full. Attitudes toward online therapy were assessed using adapted versions of the Attitude towards Telemedicine in Psychiatry and Psychotherapy (ATiPP) questionnaire. Barriers and facilitating factors were explored using open-ended questions. Descriptive statistics, correlations, and regressions were used to analyze the closed-ended questions, while responses to open-ended questions were categorized. CAPPs reported considerable experience with DMUD, but less experience with online therapy. Attitudes towards online therapy were generally neutral, with less favorable views on its use for DMUD treatment. Key barriers to implementation in outpatient care included technical challenges, lack of personal contact or control, and concerns about data security. Facilitators included access to adequate technical resources, user-friendly and evidence-based programs, interactive tools, and opportunities for regular face-to-face interactions. The results highlight the need to develop online therapy solutions that align practitioners’ needs and acceptance. However, further qualitative and quantitative research with more representative samples is essential for a more comprehensive understanding of this topic.

Adolescents are at an increased risk of developing addictive disorders due to a variety of risk factors. Addictive behaviour is characterised by a limited ability to control one's own behaviour. The potential of improved self-regulation through mindfulness-based interventions is increasingly being investigated in connection with addictive behaviour. Whether a benefit also relates to addictive disorders in childhood and adolescence is still largely unclear. This overview summarises the current state of knowledge and classifies the potential of this approach for prevention and therapy in childhood and adolescence. Results from behavioural studies show that mindfulness is associated with and mitigates the risks for substance-related and non-substance-related addictive behaviours. Mindfulness is directly related to problematic forms of substance and media use and mediates the associations with key risk factors of addictive behaviours in adolescence. The effects of mindfulness-based interventions in children and adolescents in the area of addictive behaviour can so far only be inferred indirectly. On the one hand, too few high quality studies are available for children and adolescents. On the other hand, meta-analyses with adults show that although there is a preventive and therapeutic benefit, the effects decrease with increasing study quality. The translation of promising conceptual research into effective intervention models for the vulnerable group of children and adolescents remains an important goal for future research.

Background: During adolescence, substance use and digital media exposure usually peak and can become major health risks. Prevention activities are mainly implemented in the regular school setting, and youth outside this system are not reached. A mobile app (“Meine Zeit ohne”) has been developed specifically for vocational students and encourages participants to voluntarily reduce or abstain from a self-chosen addictive behavior including the use of a substance, gambling, or a media-related habit such as gaming or social media use for 2 weeks. Results from a randomized study indicate a significant impact on health-promoting behavior change after using the app. This exploratory study focuses on the intervention arm of this study, focusing on acceptance and differential effectiveness. Objective: The aims of this study were (1) to examine the characteristics of participants who used the app, (2) to explore the effectiveness of the mobile intervention depending on how the app was used and depending on participants’ characteristics, and (3) to study how variations in app use were related to participants’ baseline characteristics. Methods: Log data from study participants in the intervention group were analyzed including the frequency of app use (in days), selection of a specific challenge, and personal relevance (ie, the user was above a predefined risk score for a certain addictive behavior) of challenge selection (“congruent use”: eg, a smoker selected a challenge related to reducing or quitting smoking). Dichotomous outcomes (change vs no change) referred to past-month substance use, gambling, and media-related behaviors. The relationship between these variables was analyzed using binary, multilevel, mixed-effects logistic regression models. Results: The intervention group consisted of 2367 vocational students, and 1458 (61.6%; mean age 19.0, SD 3.5 years; 830/1458, 56.9% male) of them provided full data. Of these 1458 students, 894 (61.3%) started a challenge and could be included in the analysis (mean 18.7, SD 3.5 years; 363/894, 40.6% female). Of these 894 students, 466 (52.1%) were considered frequent app users with more than 4 days of active use over the 2-week period. The challenge area most often chosen in the analyzed sample was related to social media use (332/894, 37.1%). A total of 407 (45.5%) of the 894 students selected a challenge in a behavioral domain of personal relevance. The effects of app use on outcomes were higher when the area of individual challenge choice was equal to the area of behavior change, challenge choice was related to a behavior of personal relevance, and the individual risk of engaging in different addictive behaviors was high. Conclusions: The domain-specific effectiveness of the program was confirmed with no spillover between behavioral domains. Effectiveness appeared to be dependent on app use and users’ characteristics.

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.

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.
