          Abstract

          Se presentan los resultados obtenidos de la estimación de la consistencia interna y la validez de constructo de la escala de Impacto de las Imágenes Femeninas presentadas por los medios de comunicación sobre Adolescentes Mujeres (IMAMIF) de Larraín, Camus, Orellana y Arrieta, en una muestra de 662 adolescentes de Santiago de Chile. Es un cuestionario de 45 afirmaciones que se evalúa a través de 5 alternativas de respuesta (1 = nunca; 5 = siempre). Se encontró una alta consistencia interna (Alfa de Cronbach 0.969). A través del Análisis Factorial Exploratorio con el método de Factores Principales (AFP), se encontró una estructura conformada por tres factores (Dieta patológica, Disconformidad corporal y Objetivación del cuerpo). En conjunto, estos tres factores explican el 84.11% de la estructura de correlación de las variables originales.

          This paper aimed to estimate reliability and construct validity of an instrument to assess the impact of female images presented by the mass media on body image of female adolescents (IMAMIF) of Larraín, Camus, Orellana and Arrieta, in a sample of 662 female adolescents. It is a questionnaire of 45 statements that evaluates the impact that female images presented by mass media, has on body image of adolescent girls. An overall Cronbach's alpha coefficient of 0.969 was obtained revealing a high internal consistency. Through an exploratory factorial analy sis with principal factors it was found a structure conformed by three factors (Pathological Diet, Body Dissatisfaction and Self Objectivation). As a whole these 3 factors explain 84.11% of the correlational structure of the original variables.

            That swimsuit becomes you: sex differences in self-objectification, restrained eating, and math performance.

            Objectification theory (B. L. Fredrickson & T. Roberts, 1997) posits that American culture socializes women to adopt observers' perspectives on their physical selves. This self-objectification is hypothesized to (a) produce body shame, which in turn leads to restrained eating, and (b) consume attentional resources, which is manifested in diminished mental performance. Two experiments manipulated self-objectification by having participants try on a swimsuit or a sweater. Experiment 1 tested 72 women and found that self-objectification increased body shame, which in turn predicted restrained eating. Experiment 2 tested 42 women and 40 men and found that these effects on body shame and restrained eating replicated for women only. Additionally, self-objectification diminished math performance for women only. Discussion centers on the causes and consequences of objectifying women's bodies.
