Evaluation of training on brief interventions for teachers: health contributions.

Objectives: to evaluate the impact of training on brief interventions for use of substances on the attitudes; and, face validity and internal consistency of Brazilian versions of the Drug and Drug Problems Perceptions Questionnaire (DDPPQ-br) and the Short Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ) for use among teachers.

Methods: methodological (N=122) and quasi-experimental study (n=27). A sociodemographic questionnaire, the DDPPQ-br and the SAAPPQ were applied before and three months after the training. For analysis, were applied the Mann-Whitney and Wilcoxon tests.

Results: the DDPQ-br and SAAPPQ were considered valid by experts. The training improved teachers' attitudes towards accountability on the approach to substance use at schools and on the readiness to perform this role. In relation to drugs, it increased the perception of support.

Conclusions: teachers' training can improve their attitudes and strengthen the school in the function of preventing substance-related harm.
