EPP0167 - Effectiveness of the KiVa antibullying program with and without the online game in Chile: a three-arm cluster randomised controlled trial
ABSTRACT
Introduction
Bullying is a major problem worldwide and Chile is no exception. Whole school-based antibullying programs offer an opportunity for preventing bullying at school. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on self-reported bullying victimization and bullying perpetration.
Objectives
To test the effectiveness of a culturally adapted version of the KiVa antibullying program in socio-economically vulnerable schools in Santiago, Chile.
Methods
We did a cluster randomized controlled trial in 5th and 6th graders at socially vulnerable schools. Schools were randomly assigned (1:1:1) to three groups: full KiVa group (including the online game), partial KiVa group (did not include the online game), and control group in which the regular school curriculum was implemented. The primary outcome was self-reported bullying victimization, measured with the Olweus Bully/Victim Questionnaire-Revised version (OBVQ-R). Students were assessed at the end of the academic year (November 2016) and 12 months later at the end of the academic year (November 2017). This trial is registered with ClinicalTrials.gov, number NCT02898324.
Results
We included 39 schools (13 in each group). The baseline survey included a total of 5923 participants, and the endpoint survey included 3968 participants. Participants in the partial KiVa group had lower victimization and lower witnessing bullying at school at the endpoint survey than those in the control group. There was no effect of the full KiVa group. No effects were found for bullying perpetration in any of the comparisons between arms.
Conclusions
The KiVa antibullying Program had small effects in its implementation in Chile.
O038 - Validation of the European Drug Addiction Prevention Trial Questionnaire (EU-Dap) for substance use screening and to assess risk and protective factors among adolescents in Chile
ABSTRACT
Introduction
Substance use is highly prevalent among Chilean adolescents, and the damage it causes at the neurobiological, psychological, and social levels is well known. However, there are no validated screening instruments that also assess risk and protective factors for this Chilean population.
Objectives
To evaluate the psychometric properties of the European Drug Addiction Prevention Trial Questionnaire (EU-Dap).
Methods
A cross-sectional study was carried out in 13 schools in Santiago of Chile. The sample included 2,261 adolescents of 10 to 14 years old. The linguistic and cultural adaptation was conducted using focus groups, the construct validity was evaluated using confirmatory factor analysis, and measures of its reliability were also determined. Furthermore, the associations regarding risk and protective factors with substance use were explored.
Results
Substance use questions were well understood by adolescents. Regarding the subscales of risk and protective factors, they needed some changes, and once completed, all new subscales had good or adequate goodness of fit adjustment. Regarding reliability, all of the new subscales had good or acceptable internal consistency according to the omega coefficient (range from 0.69 to 0.89). Finally, most of the risk and protective factors measured by the questionnaire were strongly associated with different substance use outcomes, especially those related to positive and negative beliefs or attitudes towards drugs, normative beliefs, and refusal skills.
Conclusions
The current findings suggest that the EU-Dap questionnaire is a valid and reliable instrument, and it may help to evaluate the effectiveness of preventive interventions in the future.
