Resumen
Main purpose is to address effectiveness of educational program for pre-drivers regarding driving under influence of alcohol (DUI) or riding with intoxicated driver. Young drivers and participants are at over-average risk in traffic (European Commission, 2012), and DUI is one of major contributing factors (Elliot, 2004). We have designed and developed new road-safety educational program focusing on pre-drivers in high-schools and dealing with DUI taking into account various recommendations and concepts with the integration of different approaches. In the research we have used the Theory of planned behavior (TPB, Ajzen, 1985, 1991; Forward, 2010; Moan, 2013) as a basis of influencing the components of the model. Program has been evaluated with quasi-experimental research, measurements before-after and 1-month follow-up. There were 269 participants included (16 ? 18 years old), which attended the integrated intervention program or control group. We have measured TPB components, as well as evaluation of the program. We?ve also measured phase of behavior change in accordance with Trans-theoretical model of change (TTM, Prochaska and DiClemente, 1983; 1999). Results show no significant effect of the intervention program on general attitudes and TPB components through time. There was an improvement regarding the process of change. Also the intervention group better evaluated the program and assessed the effects and satisfaction showing that there are some promising results. In discussion we address possible reasons for such results, as short duration of the program, very high results before the program etc. Practical implications of research are development and adaptation Slovene relevant instruments for measurement of TPB components for adolescents and DUI and to establish effective components of educational program to perform a road safety education with youngsters in high school level.
