The key role of rumination and perseveration processes in anger experience has been empirically supported. The tendency to ruminate has been demonstrated to be crucial in understanding pathological and adaptive behaviours. The Anger Rumination Scale (ARS) was developed to assess anger rumination frequency when people are angry, showing adequate levels of reliability and validity. However, although it has been adapted to several languages, the development of the Spanish version was still pending. The aim of this study, therefore, was to develop the Spanish adaptation of the ARS and to validate it in a general population sample (N = 388). Participants were asked to complete the ARS as well as other measures of anger (STAXI-2), anxiety (STAI-T), depression (BDI-II short form), rumination (PSWQ), and thought self-regulation (TCQ). A confirmatory factor analysis replicated the four-factor structure obtained with the original version (S-B χ2(145) = 323.26, p < .00005; CFI = .92; TLI = .90; RMSEA = .06; SRMR = .05). The resulting subscales (i.e., Angry Afterthoughts, Angry Memories, Thoughts of Revenge, and Understanding of Causes) met psychometric criteria of reliability (α = .89) and validity. In conclusion, a psychometrically sound Spanish adaptation of the ARS is now available.
El objetivo de este estudio era examinar la relación entre ira, depresión y pensamientos negativos de ira-hostilidad, y comprobar si la relación entre estos pensamientos e ira está moderada por la depresión. Una muestra de 253 adultos de la población general completó medidas de ira rasgo (STAXI-2), depresión (BDI-II) y pensamientos negativos de ira-hostilidad (IPRI). Los resultados apoyan la hipótesis de la especificidad del contenido cognitivo de Beck ya que, controlando depresión, la ira rasgo estaba asociada con los pensamientos negativos de ira-hostilidad, pero también apoyan el papel moderador de la depresión: la asociación fue más fuerte en las personas bajas en depresión que en las altas. Además, entre las personas bajas en ira rasgo, pero no entre las altas, la depresión influía en la presencia de pensamientos negativos. Los resultados subrayan la necesidad investigar la relación entre cognición y un constructo emocional negativo considerando los demás constructos emocionales relacionados.
