MIRON JUAREZ, Carlos Alberto  e  LABORIN ALVAREZ, Jesús Francisco. PSYCHOMETRIC CHARACTERISTICS OF THE SCALE OF HEURISTIC AVAILABILITY IN STOP SIGNAL TRANSGRESSION OF YOUNG DRIVERS. Rev. de psicol. y cienc. del comport. de la Unidad Académica de Cienc. Juríd. y Sociales [online]. 2016, vol.7, n.2, pp.52-67. ISSN 2007-1833.

The psychosocial research recognizes that young people make reasoning mistakes when estimating the risk of a road accident. Therefore, a descriptive and cross-sectional study was conducted with young drivers residents of Hermosillo, Sonora to obtain the psychometric properties of a scale to evaluate cognitive shortcuts in risk behaviours for violation of stop sign. A total of 436 young men and women with a driving history and an age range of 16 to 24 years old were selected. The Rasch method and the graduated response model showed the unidimensionality of the total of the items; As well as adequate criteria of discrimination and measure of affinity. Next, the factor analysis showed three factors that explain 76.6% of the total variance with a Keizer-Meyer-Olkin (KMO) index of 0.89 and a Cronbach's alpha of 0.95. Based on the results it was concluded that cognitive biases related to personal experience and parents' behavior are involved in the interpretation of road accidents of young drivers.
