Estrutura factorial do Zimbardo Time Perspective Inventory – ZTPI numa amostra de estudantes universitários portugueses

El Zimbardo Time Perspective Inventory – ZTPI (Zimbardo & Boyd, 1999) es una escala compuesta por cinco factores (pasado positivo, pasado negativo, presente hedonista, presente fatalista y futuro) que evalúa la perspectiva temporal de forma multidimensional superando, de esta forma, una de las limitaciones señaladas en otros instrumentos creados en el pasado. El objetivo de este estudio es analizar la estructura factorial de una versión portuguesa del ZTPI en una muestra de 277 estudiantes universitarios portugueses con edades comprendidas entre los 18 y los 53 años (M = 22, DE = 5.43). Fueron encontrados 5 factores que explican 35.25% de la varianza total. Estos resultados son muy parecidos a los expuestos por Zimbardo y Boyd (1999) en la publicación original del instrumento.

Predictors of Attitudes toward Cosmetic Surgery among U.S. and Colombian College Women: The Roles of Eating Behaviors and Demographic Variables

Cross-cultural studies on eating behaviors and related constructs can identify cultural and social factors that contribute to eating disorder symptomatology. Eating disorders (EDs) are a major cause for concern in the U.S., and recent studies in Colombia have shown growing rates among their female population. In addition, cosmetic surgery procedures have been increasing rapidly in both the U.S. and Colombia, and preliminary research suggests a positive relation between disordered eating and endorsement of plastic surgery. In samples of college women from Colombia and the U.S., we investigated patterns of association between disordered eating variables and cosmetic surgery acceptance. Our approach utilized separate analyses for various subcomponents of disordered eating (to determine their unique associations with cosmetic surgery acceptance) while adjusting for potentially relevant covariates and examining cross-cultural patterns. Participants were students at an urban, public college in the U.S. (n=163) and an urban, private college in Colombia (n=179). Overall, our findings suggested that participants from Colombia with greater disordered eating were more likely to endorse cosmetic surgery for social reasons, while those from the U.S. were more likely to consider undergoing cosmetic surgery for personal reasons. Differing findings between the two samples may be due to cultural and social factors, which we delineate. These findings also have potential implications for presurgical counseling of cosmetic surgery candidates.
