Randomized Controlled Trial Clinical Trial
Assessment of pain-related cognitions in chronic pain patients.
The construction of the Pain-Related Self Statements Scale (PRSS) and the Pain-Related Control Scale (PRCS) is described. The PRSS assesses situation-specific aspects of patients' cognitive coping with pain, while the PRCS measures general attitudes towards pain. ⋯ The analysis of the PRSS yielded two scales termed 'Catastrophizing' and 'Coping'; the PRSC consists of the subscales 'Helplessness' and 'Resourcefulness'. All four subscales were demonstrated to be valid and sensitive to change, and they are closely related to pain intensity and interference from pain experiences.
