AbstractThis study examined the relationship between pain self-efficacy beliefs and a range of pain behaviours, as measured by the pain behaviour questionnaire (PBQ), using a prospective design. A heterogeneous sample of 145 chronic pain patients completed sets of questionnaires on four occasions over a nine-month period. Multiple hierarchical regression analyses revealed that the subjects' confidence in their ability to perform a range of tasks despite pain (assessed at baseline), was predictive of total pain behaviour and avoidance behaviour over the nine-month study period. This finding was particularly significant because the analyses controlled for the possible effects of pain severity (at each measurement occasion), pain chronicity, age, gender, physical disability, depression, neuroticism and catastrophising. These findings suggest that pain self-efficacy beliefs are an important determinant of pain behaviours and disability associated with pain, over and above the effects of pain, distress and personality variables. In particular, higher pain self-efficacy beliefs are predictive of reduced avoidance behaviours over an extended period.
