Comparison of three school-based prevention programs to reduce cannabis use as a function of provider type

The aim of this work is fitted in line with research that intended to raise levels of quality of preventive strategies developed, analyzing the differential effectiveness of the school-based programs depending on the application agent. This study analyses the effects of three school-based prevention programs on cannabis use and attitudes towards drugs use as a function of provider type. Two hundred eighty students from the first year of Secondary Education were distributed among seven experimental conditions: six treatment conditions (experimental groups) and waiting list condition (control group). Experimental groups were determined by two factors: Type of program (Construyendo Salud program, Saluda program, Barbacana program and Control Group) andType of provider (regular teacher or external psychologist). The teachers applying the Barbacana and Saluda programs and psychologists applying the Construyendo Salud program obtain better outcomes in both cannabis use and attitudes. The results point out an interaction effect between type of program and type of applicators.
