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.

Randomized Controlled Trial Comparative Study Clinical Trial
Operant-behavioural and cognitive-behavioural treatment for chronic low back pain.
Fifty-eight outpatients with chronic low back pain were randomly allocated to one of six experimental conditions. Four conditions were designated as treatment conditions and two as control conditions. The four treatment groups consisted of: cognitive treatment (either with or without relaxation training) and behavioural treatment (either with or without relaxation training). ⋯ However, these differences were only weakly maintained at 6- and 12-month follow-ups. The behavioural conditions improved significantly more than the cognitive conditions from pre to posttreatment on the self-rated measure of functional impairment, but this difference was not maintained at 6- and 12-month follow-ups. Progressive relaxation training was found to make little contribution to either cognitive or behavioural treatments.
