Self\u2010efficacy is about patients\u2019 beliefs and abilities to handle the symptoms and implications of having arthritis. Patients\u2019 self\u2010efficacy is also a phenomenon that nurses may affect through patient education. Therefore, the aim of the present study was to investigate the factors that predict self\u2010efficacy in patients with chronic inflammatory polyarthritis.<\/jats:p><\/jats:sec><jats:sec><jats:title><jats:bold>Methods<\/jats:bold><\/jats:title><jats:p>The participants (<jats:italic>n<\/jats:italic>\u2009=\u2009132) were recruited from St Olavs University Hospital in central Norway from 2008 to 2010, and consisted of adult patients with RA, PsA or UA. We performed secondary analyses on data collected in a randomized controlled trial studying the long\u2010term effects of nurse\u2010led patient education. We carried out bivariate and multivariate linear regression analyses. The predictor variables consisted of baseline data on demographics, disease characteristics (diagnosis, disease duration, disease activity, use of disease\u2010modifying anti\u2010rheumatic drugs, pain and tiredness) and psychological variables (well\u2010being, psychological distress and patient activation). The dependent variables were self\u2010efficacy over other symptoms and self\u2010efficacy over for pain after one year.<\/jats:p><\/jats:sec><jats:sec><jats:title><jats:bold>Results<\/jats:bold><\/jats:title><jats:p>The analyses showed that female gender and patient activation predicted higher self\u2010efficacy over other symptoms, whereas female gender and better well\u2010being predicted higher self\u2010efficacy over pain.<\/jats:p><\/jats:sec><jats:sec><jats:title><jats:bold>Conclusion<\/jats:bold><\/jats:title><jats:p>To strengthen arthritis patients\u2019 self\u2010efficacy, nurses need to focus on patients\u2019 well\u2010being and activation.
