The sample consisted of 802participants (48.6% girls, 51.4% boys) aged between 9 and 16 years (M = 11.97, SD = 1.40). The Strengths and DifficultiesQuestionnaire (SDQ) and the Psychosocial Risk Index were used. Significant differences were found as a function of sex, ageand risk level. The presence of problems increased with age and under more adverse psychosocial conditions. The behaviouralsymptoms were more frequent in the boys, and the emotional symptoms and prosocial behaviours were more frequent inthe girls. The regression analyses confirmed the predictive capacity of these variables. These results have implications forthe understanding of mental health difficulties in adolescence, and they guide in the prevention for this population group.
