This study aims to explore the factorial structure of the most prevalent psychopathological symptoms in adolescence, and to explore the associations between the resulting psychopathological factors with both the Five-Factor Model of personality and the General Factor of Personality (GFP). A sample of 835 adolescents (M = 14.35, SD = 1.58; 49% girls) completed personality and psychopathology self-reports. The confirmatory factor analyses showed that a bifactor model of psychopathology, which included a general psychopathological factor (p factor) and specific factors (i.e., internalizing, externalizing, and hyperactivity and attention problems), better fitted the data than other competing models. The main associations found in the regression analyses were: neuroticism and introversion with the internalizing factor; low agreeableness with the externalizing factor; low conscientiousness with the hyperactivity and attention problems score; high neuroticism, low conscientiousness and low agreeableness with the p factor. Last, the GFP and p factor were substantially related, with  coefficients between .42 and .49 (p<.001). This study suggests that a bifactor model adequately depicts the psychopathology structure in adolescence. This structure was supported by differential associations of personality traits with each resulting factor.

ResumenAims. This work described patterns of alcohol drinking in youth that attended pregaming events (i.e., the practice The results suggest that this consumption practice (i.e., pregaming) involves distinctive risks and represents a vulnerability factor for the development of negative alcohol-related consequences.

The impact of violent video game exposure (VVGE) on aggressive behaviors has been extensively explored, but still remains controversial. Although some studies have shown slight detrimental short-term effects of VVGE, other studies have failed to find any consequence. In addition, the existence of long-lasting effects on aggressiveness, or their impact on adolescents, are still not well established. One limitation of most of these studies is that they do not control for other important risk variables for aggressive behaviors, such as personality and deviant peers, nor have they investigated the possible moderation role of these risk factors in the link between VVGE and aggression. Therefore, the main aim was to examine the additive and interactive role of VVGE, personality, and deviant peers in adolescent aggressive behaviors cross-sectionally and longitudinally. Many regression analyses and a cross-lagged autoregressive model were carried out. At both waves, aggressive behavior was predicted by having deviant peers and specific personality traits, especially low agreeableness. VVGE also presented a slight but significant effect at both waves, but it became nonsignificant when controlling for other variables. No long-term effects on the relation between VVGE and aggressive behaviors were found. Some moderation effects were consistently found at both waves: when participants reported having more deviant peers, the effects of VVGE and low agreeableness on aggressive behaviors significantly increased. These findings suggest that multiple biopsychosocial variables and their complex interplay need to be examined to gain a better understanding of the origin and expression of aggressive behavior.
