Background: This paper describes the theory and development of Take it personal! an indicated prevention programme aimed at reducing substance use in individuals with mild intellectual disabilities and borderline intellectual functioning. Method: The process of the development of Take it personal! followed the steps of the Intervention Mapping p...

Aims To assess the effectiveness of Take it personal!, a prevention programme for individuals with mild intellectual disabilities and borderline intellectual functioning (MID‐BIF) and substance use (SU). The prevention programme aims to reduce SU (alcohol, cannabis, and illicit drugs) among experimental to problematic substance users. Design A qua...

Take it personal! is een programma om risicovol gebruik van alcohol, cannabis of harddrugs te beperken bij jongeren met een licht verstandelijke beperking (LVB) en gedragsproblemen. Het programma is bedoeld voor jongeren met gebruik van experimenteel gebruik tot een milde stoornis in gebruik. Take it personal! houdt rekening met verschillende perso...

In dit artikel bespreken we de wetenschappelijke kennis over de effecten van interventies die jongeren helpen bij het stoppen met roken en interventies die moeten voorkomen dat jongeren beginnen met roken. Daarnaast beschrijven we de interventies die in Nederland, na een kwaliteitstoetsing, zijn opgenomen in de databank van het RIVM Centrum Gezond...

In this paper we present three studies that have been conducted amongst first year prevocational and special education students in which we examined whether narratives increase the effectiveness of health education materials. We compare various forms of narratives with standard expository materials. Results show short-term effects of exposure to he...

Health education about alcohol and tobacco use for low literate adolescents: the role of connectives This paper first overviews the results of eight experiments that examined the effects of school health communication about alcohol and tobacco on low educated adolescents. Overall, it was found that there was a short term knowledge increase but only...

Objective: This study tests the effectiveness of narrative versus informational smoking education on smoking beliefs, attitudes and intentions of low-educated adolescents. Design: A field experiment with three waves of data collection was conducted. Participants (N = 256) were students who attend lower secondary education. At the first and third wa...

Aim To explore whether specific groups of adolescents (i.e., scoring high on personality risk traits, having a lower education level, or being male) benefit more from the Preventure intervention with regard to curbing their drinking behaviour. Design A clustered randomized controlled trial, with participants randomly assigned to a 2-session coping...

- In this article, we discuss the scientific knowledge on the effects of interventions that help young people to quit smoking and interventions that should prevent young people from starting to smoke.- We also describe the interventions in the Netherlands that, after a quality assessment, have been included in the database of the National Institute...

This study aims to provide insight into which modality is most effective for educating low-educated adolescents about smoking. It compares the persuasive effects of print and audiovisual smoking education materials. We conducted a field experiment with two conditions (print vs. video) and three measurement times (Time 1, Time 2, and Time 3). A tota...

Problematic substance use and mental health problems often co-occur in adolescents. Effective school-based interventions that are brief and target multiple problems are promising in the field of health promotion. Preventure is a brief, school-based, selective preventive intervention, tailored to four personality profiles. Preventure has already pro...

Background: Findings from systematic reviews and meta-analyses about the effectiveness of school-based programmes to prevent or reduce substance abuse are inconclusive. We hypothesise that in order to be effective, programmes have to be aligned with the developmental stages of the intended target group (childhood, early, middle, or late adolescenc...

Background: Traditionally most health education materials are written in an expository non-narrative format. Scholars have argued that the effectiveness of materials may increase when these texts are replaced by narrative texts, and that the non-narrative texts should be replaced by narrative texts. However, no previous studies have tested these c...

The effectiveness of Preventure was tested on drinking behaviour of young adolescents in secondary education in The Netherlands. A cluster randomized controlled trial was carried out, with participants randomly assigned to a 2-session coping skills intervention or a control no-intervention condition. Fifteen secondary schools throughout The Netherl...

To evaluate the effectiveness of the Healthy School and Drugs programme on alcohol, tobacco, and marijuana use among Dutch early adolescents. Randomized clustered trial with two intervention conditions (i.e., e-learning and integral). General population of 11 to 15-year-old adolescents in the Netherlands. A total of 3,784 students of 23 Dutch secon...

In deze studie wordt verslag gedaan van een gerandomiseerd onderzoek met controlegroep naar De Gezonde School en Genotmiddelen dat bestaat uit: (1) een lesprogramma en (2) een programma met de methode verhalend ontwerpen. Zeven basisscholen met 251 leerlingen (M = 10.86; SD = .71; 49% jongens) deden mee. Deze scholen werden willekeurig toegewezen a...

To examine the mediation by drinking motives of the association between personality traits (negative thinking, anxiety sensitivity, impulsivity, and sensation seeking) and alcohol frequency, binge drinking, and alcohol-related problems using a sample of students (n=3053) aged between 13 and 15, who reported lifetime use of alcohol. Structural equat...

Various studies found personality to be related to substance use, but little attention is paid to the role of personality risk dimensions with regard to an early onset of alcohol, tobacco, and marijuana use. Therefore, the current study used a variable-centered approach to examine whether anxiety sensitivity, hopelessness, sensation seeking, and im...

In comparison to other Europe countries, Dutch adolescents are at the top in drinking frequency and binge drinking. A total of 75% of the Dutch 12 to 16 year olds who drink alcohol also engage in binge drinking. A prevention programme called Preventure was developed in Canada to prevent adolescents from binge drinking. This article describes a stud...

Alcoholmisbruik gedurende de adolescentie hangt samen met een breed scala aan problemen op zowel korte als lange termijn. Universele preventieprogramma’s zijn echter weinig effectief gebleken in het voorkomen van alcoholmisbruik onder jongeren. In dit artikel wordt een overzicht geschetst van het aanbod aan selectieve en gëındiceerde preventie en w...

We examined whether anxiety sensitivity, hopelessness, sensation seeking, and impulsivity (i.e., revised version of the Substance Use Risk Profile Scale) would be related to the lifetime prevalence and age of onset of alcohol, tobacco, and cannabis use, and to polydrug use in early adolescence. Baseline data of a broader effectiveness study were us...

Het drinken van alcohol op jonge leeftijd brengt verschillende risico’s met zich mee voor onder andere de schoolprestaties en de hersenontwikkeling. Onderzoek naar de effecten van de nieuwe interventie Preventie Alcoholgebruik Scholieren (PAS) laat zien dat als ouders en jongeren worden betrokken in preventie, het beginnen met (zwaar) wekelijks dri...

Substance use is highly prevalent among Dutch adolescents. The Healthy School and Drugs program is a nationally implemented school-based prevention program aimed at reducing early and excessive substance use among adolescents. Although the program's effectiveness was tested in a quasi-experimental design before, many program changes were made after...
