Resumen

Introduction: the negative effects of anger on health highlight the value of developing short, reliable, and valid instruments that allow its assessment whether for the purpose of research, clinical diagnosis, and/or evaluation of interventions aimed at reducing it effectively. Objective: the primary aim of this research was to determine the construct, convergent, and discriminant validity, as well as the factorial invariance, of a new scale to measure anger proneness. Method: a confirmatory factorial analysis was used. Results: an online nonprobability sample composed of 457 participants (35.2% men and 64.8% women), with a mean age of 36.87 years (SD = 12.513) was recruited. The unidimensional model of the García’s Brief Scale for Assessing Anger Proneness (APS-G scale) shows a good data fit (df = 2; χ2 = 5.515; χ2/df = 2.575; CFI = .993; GFI = .996; RMSEA = .051; SRMR = .0193). There are factorial, configural, metric, unrestricted, strong, and strict factorial invariances between men and women. Likewise, a positive correlation coefficient exists between the APS-G scale and the State-Trait Anger Expression Inventory-2 (STAXI-2) (r = .561; p < .01); on the other hand, there is a negative correlation coefficient between the studied scale and the Satisfaction with Life Scale (SWLS) (r = -.179; p < .01). Discussion and conclusion: a new reliable and valid instrument to measure anger prone-ness has been created, and its use is proposed for research and screening purposes with Spanish-speaking population.
