Attention to chronic pain is dependent upon pain-related fear

Pain interrupts, distracts, and is difficult to disengage from. In this study, the role of pain-related fear in moderating attentional interference produced by chronic pain was investigated. Forty chronic pain patients completed a list of questionnaires assessing pain severity, pain-related fear (Tampa Scale for Kinesiophobia), and negative affect (Negative Emotionality scale). Attentional interference was measured by a numerical interference test. Multiple regression analysis revealed that the attentional interference was best predicted by the interaction between pain severity and pain-related fear. These results are discussed in terms of how pain-related fear creates a hypervigilance to pain.
