摘要：El autoconcepto es uno de los factores que permite al ser humano gozar de salud y bienestar emocional durante su desarrollo evolutivo. Musitu, García y Gutiérrez (1991) mencionan que el autoconcepto es la percepción que tiene la persona de sí misma en base a la observación de sus capacidades y limitaciones y que le permite tener un sentido de la propia identidad. Quien posee un autoconcepto positivo, podrá ser capaz de aceptar retos, emprender desafíos, perder el temor, aventurarse y experimentar cosas nuevas. El estudio que se informa analiza las propiedades psicométricas de la Escala de Autoconcepto AF5 de García y Musitu. Se utilizó un diseño transver - sal con una muestra de 861 estudiantes de una universidad privada de Tarapoto (Perú). La escala es de tipo Likert y es tá compuesta por 30 ítems distribuidos en cinco dimensiones: autoconcepto académico, autoconcepto social, autoconcepto emo cional, autoconcep to familiar y autoconcepto físico. En primera instancia se realizó un análisis fac torial exploratorio (AFE) con rotación Varimax en el que cinco factores explicaron el 51.98% de la variancia total. Posteriormente, se realizó con la técnica de ecuaciones estructurales un análisis factorial confirmatorio (AFC) para el cual se realizaron cuatro re-especificaciones. La solución final obtuvo índices de ajuste adecuados (RMSEA = .05; p = .05; TL I = .90; CFI = .92, CMIN / DF = 3.521; GFI = .92 y AGFI = .90). Entre los principales hallazgos se encontró que la solución final confirma la propuesta del autoconcepto como un constructo multidimensional de cinco factores. Sin embargo, el número de ítems difiere ligeramente. No se logró identificar una solución de segundo orden que evalúe el autoconcepto global. Los valores de confiabilidad para las escalas oscilaron entre .771 y .835. Los resultados obtenidos coinciden con los hallaz gos de los autores originales por lo que se afirma que el AF5 es un instrumento válido y confiable para estudiantes universitarios peruanos.
其他摘要：Self-concept is one of the factors that allows humans to live healthy and with emotional wellbeing during their evolutionary development. Musitu, García, and Gutiérrez (1991) mention that selfconcept is the perception that people have of themselves based on the observation of their capa bilities and limitations, which allows them to have a sense of identity. People having a positive self-concept may be able to accept dares, undertake challenges, lose fear, venture out, and try new things. In this regard, the present study analyzes the psychometric properties of García and Musitu’s AF5 Selfconcept Scale. We used a cross-sectional design and the study sample consisted of 861 students of both genders (467 female and 394 male) in a private university in Tarapoto (Perú); who filled out the AF5 scale consisting of 30 items divided into five dimensions: academic self-con cept, social self-con - cept, emotional self-concept, family self-concept, and physical self-concept, which are answered through a Likert scale. Firstly, we calculated the Kaiser-Meyer-Olkin (KMO) sampling adequacy index for total scale where we obtained .885 and Bartlett’s index of sphericity was 9377.994 (df = 435, p = .001), these values allowed us to do the exploratory factor analysis (EFA) with Varimax rotation where five factors explained the 51.98% of the total variance. Later, a confirmatory factor analysis (CFA) was executed through the technique of structural equations for which four re-specification were done, the final solution got indexes of adequate adjustments (RMSEA = .05, p = .05; TLI = .90, CFI = .92, CMIN / DF = 3.521; GFI = .92, and AGFI = .90). Among the main findings we found that the final solution confirms the proposal of selfconcept as a multidimensional construct of five factors; however, the number of items differs slightly. It was not possible to identify a second order solution that may evaluate global self-con - cept. With respect to reliability, values for scales ranged from alpha equal to .771 and .835. The re - sults obtained coincide with the findings of the original authors; therefore, we state that the AF5 is a valid and reliable instrument for Peruvian uni ver - sity students.
