The aim of this study was to analyze the psychometric properties of the Spanish version (COPE-28) of the Brief Cope Inventory (Carver, 1997) with 1204 adolescents (M= 15.3 years, SD= 1.8). An exploratory factor analysis showed a solution of eight factors that explains 54.19% of the variance (KMO= .752 and Bartlett’s test was significant, χ2= 6625.262, df= 378, p< .001). The internal consistency for the total score of the COPE-28 was .78. Concurrent validity was obtained with the Aggression Questionnaire (AQ; Buss & Perry, 1992) and Reactive and Proactive Aggression Questionnaire (RPQ; Raine et al., 2006). The most significant correlations were between Self-incrimination (COPE-28) and Hostility (AQ) (r= 0.414), Disconnection (COPE-28) and Proactive aggression (RPQ) (r= .315), and finally Substance use (COPE-28) with Reactive aggression (RPQ) (r= .360), Proactive aggression (RPQ) (r= .455) and Physical aggression (AQ) (r= .392). These data support the reliability and validity of COPE-28 but point to the need for further studies.
