Abstract
BACKGROUND: Qualitative evidence points to the importance of both mental health-related barriers and benefits to exercise in chronic pain, yet this bidirectional relationship has not been established quantitatively. METHODS: 89 adults with chronic pain (75 female, Age: M = 34.7, SD=13.2), and 89 demographically-matched individuals without chronic pain (73 female, Age: M = 32.0, SD=13.3) self-reported demographic and health information, mental health-related barriers and benefits to exercise, and leisure-time exercise activity. RESULTS: Adults with chronic pain had significantly higher scores on mental health-related barriers to exercise, and lower leisure-time exercise participation than adults without chronic pain. The groups did not differ on mental health-related benefits of exercise scores. Benefits scores positively predicted exercise, yet there was a significant negative interaction between pain and benefit scores, indicating a weaker positive relationship between benefits and exercise for adults with chronic pain than for those without chronic pain. Barrier scores significantly negatively predicted exercise engagement, but did not interact significantly with chronic pain. CONCLUSION: Mental health-related barriers and benefits to exercise are important considerations when prescribing exercise for adults with chronic pain. Adults with chronic pain may require individualised support to address mental health-related barriers to leisure-time exercise.
