MARTINEZ MIR, Raúl. Validation of the Cook and Medley Hostility Scale in Adult Population from Northwestern Mexico. Acta de investigación psicol [online]. 2022, vol.12, n.1, pp.107-116.  Epub Apr 24, 2023. ISSN 2007-4719.  https://doi.org/10.22201/fpsi.20074719e.2022.1.429.

Based on the description of the Type A Behavior Pattern (PCTA) as a risk factor for cardiovascular disease and the subsequent confirmation of hostility as one of the main predictors of the condition, different measurement scales have been used for its evaluation. One of the most cited is the Cook and Medley Hostility Scale (HO) (1954), which was initially created with English-speaking teachers, and later used with cardiovascular patients to identify the presence of the risk factor. The objective of this work was to determinate the reliability and validity of the hostility scale for the population of northwestern Mexico. It was used in a sample of 1669 participants with an age range between 30 and 85 years, a mean of 38 and a standard deviation of 10.16. This sample has a higher age range than other studies that tend to use students. A confirmatory factor analysis showed a factor structure with five factors, following the model of Barefoot et al. (1989, 1991), with an explained variance of 29.67% and an internal consistency index of 0.86, also obtaining that the indicators of goodness of fit of the data were optimal. We conclude that the hostility scale has appropriate reliability and validity, which will allow its use to measure the construct in the adult population, which allows its use in cardiovascular patients to measure the hostility that is shown as a risk factor for these diseases.
