The mediating role of anger rumination on the relationship between anger and pain intensity in chronic musculoskeletal pain patients

Experience of anger is an indicator of the living conditions of patients with chronic musculoskeletal pain disorders. The aim of this study was to examine the mediating role of anger rumination on the relationship between anger and pain intensity in chronical musculoskeletal pain patients. For this purpose, a sample of ۱۰۹ chronic musculoskeletal pain patients selected by convenience sampling method. Multidimensional pain questionnaire, multidimensional anger inventory and anger rumination scale used for collecting data. The present study is descriptive-correlation and analysis of data carried using simple correlation coefficient and regression analysis by Baron and Kenny method. Finding showed that anger and all of its dimensions except anger-eliciting situations and anger-out predicted pain intensity. Anger and all of its dimensions predicted anger rumination. In addition, results showed that anger rumination completely mediated the relationship between anger and pain intensity. Furthermore, the mediator role of anger rumination confirmed only for internal dimensions that had a significant relationship with the pain severity, such as anger arousal, hostile outlook and anger-in. However, this mediator role of anger was not confirmed for the dimensions with external nature (such as anger-eliciting situations and anger out), and there was not any significant correlations between pain severity and these dimensions. In general, anger rumination exacerbates the negative effects of anger on the pain severity in patients with chronic musculoskeletal pain.
