Resumen El propósito del estudio fue desarrollar una escala que mida la expectativa de comportamiento ambiental de otros y observar si hay relación con la conducta proambiental autorreportada. Se generaron 13 reactivos de respuesta tipo Likert, aplicados a una muestra de 218 adultos jóvenes mexicanos. El análisis factorial exploratorio muestra una estructura bifactorial, que distingue entre la expectativa de comportamiento proambiental y antiambiental, cuyos índices de consistencia interna fueron alfa = 0.77 y alfa = 0.79, que explican el 57.65% de la varianza. Se les aplicó también una escala de conductas proambientales. Mediante un modelo de ecuaciones estructurales se mostró que el factor de expectativa de comportamiento en estudio tuvo un efecto significativo sobre la conducta proambiental. Los resultados muestran evidencia de una escala bifactorial con propiedades psicométricas aceptables.
Abstract The purpose of this study was to develop an instrument to measure expectation of others' environmental behavior, and notice if there is a relationship between this variable and self-report of pro-environmental behaviors. Thirteen items Likert-type were development, and was applied to a sample of two hundred eighteen Mexican young adults. The exploratory factor analysis shows a bi-factorial structure distinguishes between, expectation of pro-environmental behavior, and expectation of anti-environmental behavior. Their Cronbach's alpha score was 0.77 and 0.79; both factors accounted for 57.65% of the variance. A scale of pro-environmental actions was applied too. A structural equation model showed that the factor expectation of pro-environmental behavior has a significant effect on pro-environmental actions. The result shows evidence for bi-factorial scale with acceptable psychometrics properties.
