La agresión es una problemática de importancia para los adolescentes, por ello, la comprensión de este fenómeno es crucial. El propósito de este estudio es analizar la validez estructural y la invarianza del Reactive/Proactive Aggression Questionnaire (RPQ) en adolescentes limeños institucionalizados y no institucionalizados. Se seleccionaron 344 adolescentes hombres, entre 15 y 17 años (Medad = 16.055, DEedad = .674), el 51.16% se encontraban institucionalizados en un centro juvenil de diagnóstico y rehabilitación social debido a conflictos con la ley penal. Los resultados muestran que el modelo bidimensional del RPQ presenta índices de ajuste relativamente aceptables (SB-χ2 = 461.463(229), CFI = .914, RMSEA = .054 [.047-.062]). Además, en ambos grupos, se estableció la invarianza configuracional, métrica, escalar y estricta. Se reportan coeficientes omega adecuados para la agresión reactiva (ω = .797) y agresión proactiva (ω = .837). Se concluye que el RPQ es una medida bidimensional, parsimoniosa e interpretable que mide la agresión reactiva y proactiva en los adolescentes ya mencionados. Aggression is an important problem of adolescents, the understanding of this phenomenon is crucial. The pur-pose of this study is to analyze the structural validity and invariance of the Reactive/Proactive Aggression Question-naire (RPQ) in institutionalized and non-institutionalized adolescents from Lima. 344 male adolescents were se-lected, among 15 and 17 years old (Mage = 16.055, SDage= .674), 51.16% were institutionalized in a youth center for diagnosis and social rehabilitation due to conflicts with criminal law. The results show that the two-dimensional model of the RPQ presents relatively acceptable fit indices (SB-χ2 = 461.463(229), CFI = .914, RMSEA = .054 [.047-.062]). Additionally, the configurational, metric, scalar and strict invariance was established in both groups. Adequate omega coefficients are reported for reactive aggression (ω = .797) and proactive aggression (ω = .837). It is concluded that the RPQ is a two-dimensional, parsimonious, and in-terpretable measure that determines reactive and proactive aggression in the aforementioned adolescents.
