Abstract

Pain beliefs influence understanding of pain mechanisms and outcomes. This study in rheumatologic conditions sought to determine a relationship between beliefs about pain and functioning. Participants in Arthritis New Zealand’s (ANZ) exercise and education programmes were used. Demographic data and validated instruments used included the Arthritis Impact Measurement Scale 2nd version-Short Form (AIMS2-SF) to measure functioning, and two scales of organic and psychological beliefs in Pain Beliefs Questionnaires (PBQ) to measure pain beliefs. 236 Members of ANZ were surveyed anonymously with AIMS2-SF and PBQ, with a 61% response rate; 144 responses were entered into the database. This study used α of 0.05 and a 1-β of 0.8 to detect for significant effect size estimated to be 𝑟 = 0 . 2 5 . Analysis revealed a significant relationship between organic beliefs scale of PBQ and functioning of AIMS2-SF, with an 𝑟 value of 0.32 and 𝑃 value of 0.00008. No relationship was found between psychological beliefs scale of PBQ and AIMS2-SF. Organic pain beliefs are associated with poorer functioning. Psychological pain beliefs are not. Beliefs might have been modified by ANZ programmes. Clinicians should address organic pain beliefs early in consultation. Causal links between organic pain beliefs and functioning should be clarified.
