Latent Classes of Substance Use in Young Adults - A Systematic Review.

Background: This systematic review provides an overview of studies on latent classes related to the substance use among young adults (18-25 years). Identifying these classes helps to detect high-risk groups, setting a base for selective prevention.Methods: This systematic literature review included peer-reviewed studies (published up to February, 2021) that identified latent classes and investigated predictors of latent classes relating to the use of marijuana, alcohol and/or other substances within samples of young adults.Results: Twenty studies (sample sizes N = 171 to N = 21945) met the inclusion criteria. 14 studies identified 'low-level engagers', 'light alcohol and tobacco use', 'heavy alcohol and tobacco use' and 'heavy use/polysubstance use' classes. Four studies differentiated within the 'heavy/polysubstance' class and found 'traditional clubdrugs', 'hallucinogens' and 'wide-range illicit drugs' classes. Male gender and white race predicted membership of the 'heavy use/polysubstance use' class consistently across studies. Other predictors of polysubstance use that were consistent across studies were peer substance use, depressive symptoms, parental drinking and participating in an honor society.Conclusions: The investigated predictors of class membership provide insight into social settings and characteristics that predict heavy use or polysubstance use. They can contribute to the development of effective prevention interventions by allowing for a more targeted approach.

Acquiring Financial Support for Children's Sports Participation: Co-Creating a Socially Safe Environment for Parents from Low-Income Families.

Despite the many benefits of club-organized sports participation for children, sports participation is lower among children from low-income families than among those from middle- or high-income families. Social safety experienced by parents from low-income families is an important facilitator for parents to request financial support for their children's sports participation. Therefore, the first aim of this study was to better understand parental social (un)safety in the context of acquiring financial support for children's sports participation and how to create a safe social environment for low-income parents to request and receive this financial support. The second aim was to describe the co-creation process, which was organized to contribute to social safety solutions. To reach these goals, we applied a participatory action research method in the form of four co-creation sessions with professionals and an expert-by-experience, as well as a group interview with parents from low-income families. The data analysis included a thematic analysis of the qualitative data. The results showed that from the perspective of parents, social safety encompassed various aspects such as understandable information, procedures based on trust, and efficient referral processes. Sport clubs were identified as the primary source of information for parents. Regarding the co-creation process, the study found that stakeholders tended to overestimate parental social safety levels. Although the stakeholders enjoyed and learned from the sessions, differences in prior knowledge and a lack of a shared perspective on the purpose of the sessions made it challenging to collaboratively create solutions. The study's recommendations include strategies for increasing parental social safety and facilitating more effective co-creation processes. The findings of this study can be used to inform the development of interventions that contribute to a social environment in which parents from low-income families feel safe to request and receive financial support for their children's sports participation.

Facilitating Children's Club-Organized Sports Participation: Person-Environment Misfits Experienced by Parents from Low-Income Families.

Despite the many benefits of club-organized sports participation for children, studies have shown that sports participation is lower among children from low-income families than among children from middle- or high-income families. Adopting a socioecological perspective, the main aim of our study was to identify and describe experiences of person-environment (PE) misfits in relation to parental facilitation of children's sports participation. We conducted 24 interviews with parents from low-income families. PE misfits were found in multiple behaviors related to the facilitation of children's sports participation: financing sports participation; planning and investing time; transporting children; acquiring, processing, and providing information; and arranging support. Across these PE misfits, influential attributes were found on the individual level (e.g., skills) as well as within the social, policy, physical, and information environment. In response to PE misfits experienced, parents deployed multiple strategies to reduce these PE misfits, aimed at enhancing either themselves (e.g., increasing financial capacities) or their environments (e.g., arranging social support). These results provide an insight into experienced PE misfits that took the form of multiple specific behaviors which parents found difficult while facilitating their children's sports participation. Furthermore, the results provide insight into the environmental and individual attributes that were involved in these PE misfits, and into how parents modified themselves or their environments in order to make their environments more supportive. The study contributes to future research on individual and environmental influences on parental facilitation of their children's sports participation, as well as on the development of multilevel interventions aimed at increasing sports participation among children from low-income families.

Characterization of ecotoxicological risks from unintentional mixture exposures calculated from European freshwater monitoring data: Forwarding prospective chemical risk management.

Current regulatory chemical safety assessments do not acknowledge that ambient exposures are to multiple chemicals at the same time. As a result, potentially harmful exposures to unintentional mixtures may occur, leading to potential insufficient protection of the environment. The present study describes cumulative environmental risk assessment results for European fresh water ecosystems, based on the NORMAN chemical surface water monitoring database (1998-2016). It aims to characterize the magnitude of the mixture problem and the relative contribution of chemicals to the mixture risk, and evaluates how cumulative risks reduce when the acceptable risk per single chemical is fractionally lowered. Available monitoring data were curated and aggregated to 26,631 place-time combinations with at least two chemicals, of which 376 place-time combinations had at least 25 chemicals identified above the Limit of Detection. Various risk metrics were based on measured environmental concentrations (MECs). Mixture risk characterization ratio's (ΣRCRs) ≥ 1 were found for 39% of the place-time combinations, with few chemicals dominating the ΣRCR. Analyses of mixture toxic pressures, expressed as multi-substance Potentially Affected Fractions of species based on No Observed Effect Concentrations (msPAFNOEC), showed similar outcomes. Small fractional reductions of the ambient chemical concentrations give a steep increase of the percentage of sufficiently protected water bodies (i.e. ΣRCR < 1 and msPAFNOEC < 5%). Scientific and regulatory aspects of these results are discussed, especially with reference to the representativeness of the monitoring data for characterizing ambient mixtures, the robustness of the findings, and the possible regulatory implementation of the concept of a Mixture Allocation Factor (MAF) for prospective chemicals risk management. Although the monitoring data do not represent the full spectrum of ambient mixture exposures in Europe, results show the need for adapting policies to reach European Union goals for a toxic-free environment and underpin the utility and possible magnitude of a MAF.

Do Dutch News Reports About Suicide Refer to Suicide Prevention Strategies?

Background: Previous research and media guidelines suggest two potential protective characteristics of news reports about suicide: (1) individuals who adopt coping strategies other than suicidal behavior are described and (2) information about resources for support is provided. Aims: Our aim was to investigate the extent to which Dutch news reports contain these two potential protective characteristics. Method: A random selection of Dutch news reports (N = 296) published in the previous 6 months was coded on the presence of each of the two potential protective characteristics. Results: Of the 296 news reports, 50 news reports (16.9%) mentioned available resources for support. Only one news report (0.3%) described an individual who adopted coping strategies other than suicidal behavior in adverse circumstances, namely, entering a mental health care institution. Limitations: One of the limitations is that, owing to the selection of news reports, conclusions pertain only to news reports published by Dutch media sources with the most readership in that period. Conclusion: The results of this study suggest that current knowledge about protective characteristics of news reports on suicide needs to be better implemented in The Netherlands.

Responsibly Communicating Delays After Suicides on Railways.

Background: By communicating collision with a person as a reason for post-suicide railway delays, railway companies may involuntarily communicate to the public that colliding with a train is a suicide method. Aims: To compare the impact of the collision with a person delay announcement with an announcement about emergency services and one about collision with an animal (control announcement), we measured suicide-related emotions, associations with suicide, and announcement appreciation. Method: A randomized controlled online experiment (N = 664) was conducted. Results: After exposure to the collision with a person announcement, participants were 9.1 times more likely to indicate suicide as the most probable reason for the delay than after the emergency services announcement. The emotional impact of both announcements was low. Still, participants reported more anger toward the victim after exposure to the collision with a person announcement than after exposure to the emergency services announcement. Announcement appreciation was significantly higher after exposure to collision with a person. Limitations: This online experiment may have reflected real-life situations concerning train delays to only a limited extent. Conclusion: From the perspective of suicide prevention, the emergency services announcement is a more appropriate delay announcement than the collision with a person announcement.

Cue-Reminders to Prevent Health-Risk Behaviors: A Systematic Review.

Introduction: It has been proposed that the use of cue-reminders may increase the effectiveness of interventions that aim to prevent health-risk behaviors (i.e., having unsafe sex, unhealthy dietary intake, lack of physical activity, and substance use). The aim of this systematic review was to explore whether there is evidence supporting this proposition, and to explore how cue-reminders are applied in health-risk behavior interventions to date. Method: We systemically reviewed (non-) randomized trials that examine differences in health-risk behaviors between an experimental group receiving an intervention with exposure to a cue-reminder and a control group receiving the intervention without such cue. Results: Six studies were eligible for inclusion. The studies differed in sample and research design, and how the cue-reminder was applied. One study demonstrated a positive and small effect, and one study found a negative medium effect of the cue-reminder. In the remaining studies, the effect sizes were positive but non-significant. Discussion: It is unclear whether complementing health-risk behavior interventions with cue-reminders increases the effectiveness of these interventions. Further investigation and experimentation into the efficiency and effectiveness of cue-reminders is needed before health-risk behavior interventions are complemented with cue-reminders.

Televised entertainment-education to prevent adolescent alcohol use: perceived realism, enjoyment, and impact.

Alcohol use among adolescents is a concern in the Netherlands because of its high prevalence and risks. To discourage adolescents from drinking alcohol, a televised entertainment-education (E-E) intervention was developed. This study investigated responses of adolescents on perceived realism and enjoyment of the E-E intervention, as well as its impact on alcohol drinking behavior. Viewers perceived the E-E narratives to be credible and enjoyable but did not relate to the characters in the narratives. However, exposure to the E-E intervention predicted desired changes in alcohol drinking behavior, intentions to decrease alcohol use, and perceived normative pressure, especially in less educated viewers. These findings demonstrate that E-E is a promising strategy to target adolescent alcohol use. Future research will focus on the individual processes and story elements that account for the positive results.
