Validity of construct of the Cook and Medley Hostility Scale in a student group

The aim of this research was to assess the validity of construct of the Cook and Medley Hostility Scale. With this purpose were estimated, through confirmatory factorial analyses, different measurement models previously suggested in the literature. The results showed the multidimensional nature of hostility and, in general, they support the model proposed by Barefoot and colleagues (1989). However, some psychometric deficiencies were found, such as the low reliability of some of the subscales. Finally, it was observed that dimensions of hostility were negatively associated to perceived social support and social skills, and positively correlated to different dimensions of experience and expression of anger.
