Overall, the outcome for acute<unk>  is positive. Pain and disability usually improve a great deal in the first six weeks, with complete recovery reported by 40 to 90%. In those who still have symptoms after six weeks, improvement is generally slower with only small gains up to one year. At one year, pain and disability levels are<unk>  to minimal in most people. Distress, previous<unk> , and job satisfaction are predictors of long-term outcome after an episode of acute pain. Certain psychological problems such as depression, or unhappiness due to loss of employment may prolong the episode of<unk> . Following a first episode of back pain, recurrences occur in more than half of people. For persistent<unk> , the short-term outcome is also positive, with improvement in the first six weeks but very little improvement after that. At one year, those with chronic<unk>  usually continue to have moderate pain and disability. People at higher risk of long-term disability include those with poor coping skills or with fear of activity (2.5 times more likely to have poor outcomes at one year), those with a poor ability to cope with pain, functional impairments, poor general health, or a significant psychiatric or psychological component to the pain (Waddell's signs). Prognosis may be influenced by expectations, with those having positive expectations of recovery related to higher likelihood of returning to work and overall outcomes.
