[Influence of cognitive-emotional processing on pain and disability. A psychobiological perspective].

In the context of the biopsychosocial pain concept and on the basis of empirical evidence those cognitive traits and mechanisms are described that have reliably been found to be potent moderators of pain and disability. Expectations of patients which result in placebo or nocebo effects as well as more complex belief patterns influence subjective pain severity as well as disability. Especially beliefs which relate to self-control, self-efficacy or its counterpart helplessness can distinctly moderate pain, lead to an increase or mitigation of pain intensity and associated disability. The impact of most of these cognitive factors, such as catastrophizing, low self-efficacy, certain pain beliefs, low acceptance or fear of pain can be integrated into the general stress coping model. It denominates situational appraisal and self-appraisal processes beside actual coping behaviors as the main psychological factors influencing severity of pain and related disability.
