Mental health app boost my mood (BMM) as preventive early intervention for adolescents with (sub)clinical depressive symptoms.

Background: Depression is a common mental disorder. Detecting (sub)clinical depressive symptoms in adolescents at an early stage and offering a low-threshold early intervention can minimize the risk of serious and/or long-term depression. As such, a digital intervention can be a low-threshold preventive and early intervention.

What Do Young Adults Expect from the Recreational Use of Ecstasy (3,4-Methylenedioxymethamphetamine/Molly)? A Latent Class Analysis of a Convenience Sample of Dutch Young Adults.

Introduction: This study offers insights into Dutch young people's expected social and personal consequences of ecstasy use. Substance use expectancies are assumed to be an essential component in explaining substance use behaviour and, therefore, the development of effective substance use prevention and treatment strategies.

Method: Dutch young adults with an online interest in drug-related social media posts were targeted with an online survey about their use of alcohol and drugs.

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

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. 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.

The Intervening Role of Conversational Frequency and Valence in a School-Based Health Intervention.

School-based health interventions are potentially an effective method to communicate health messages to adolescents. Unfortunately, effectiveness of such interventions is limited. Research in other contexts has shown that interpersonal communication can influence the effectiveness of health programs, but this has not been thoroughly tested for school-based health interventions.

The Antecedents and Consequences of Interpersonal Communication during a School-based Health Intervention.

School-based health interventions often have limited and inconsistent effects. Although interpersonal communication likely is important, hardly any studies have investigated interpersonal communication of students with their friends, classmates, and parents about the health programs and health behaviors in school-based health interventions. In a two-wave prospective study of 389 adolescents focusing on three health behaviors (i.
