Although many factors have been recognized as important contributors to the pain experiences and functional abilities of fibromyalgia patients, the factors that are most impactful (and therefore represent optimal targets for intervention) are still unclear. The aim of the present study was to examine the pathways among depression, self\u2010efficacy, pain, and physical functioning in a large sample of fibromyalgia patients over a 1\u2010year timeframe.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data from 462 participants (441 women) were analyzed using an autoregressive path analytical model with first\u2010 and second\u2010order cross\u2010lagged effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Self\u2010efficacy was the only significant predictor of depression, physical functioning, and pain intensity ratings across time. Physical functioning at 6 months predicted self\u2010efficacy at 1 year; no other factors related significantly to self\u2010efficacy in the model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our model suggests that self\u2010efficacy is a salient factor in fibromyalgia symptomatology. Our findings support designing interventions that use a multimodal approach, with an explicit focus on combining exercise (or other means) to improve physical functioning and psychotherapy (e.g., cognitive\u2013behavioral therapy) with the intention of reprocessing the functional improvements and the implications of these improvements for the patients' ability to manage their fibromyalgia symptoms. By doing so, self\u2010efficacy should be enhanced, and this would produce the greatest and broadest benefits for fibromyalgia patients.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acr.21792","type":"journal-article","created":{"date-parts":[[2012,11,20]],"date-time":"2012-11-20T09:03:32Z","timestamp":1353402212000},"page":"251-256","source":"Crossref","is-referenced-by-count":19,"title":["Predictors
