This study examined the relationship between self-efficacy beliefs and pain during the performance of stair climbing and lifting/carrying tasks on speed of movement, ratings of task difficulty, and perceived task ability in a group of patients with osteoarthritis (OA) of the knee. Seventy-nine patients with knee OA completed the tasks in a controlled laboratory setting. Before completing each task, patients' self-efficacy was assessed; following task performance they rated (a) the most intense knee pain experienced, (b) the difficulty of the task, and (c) their perceived ability as they performed each task. Results demonstrated that, even after controlling for physical function, self-efficacy, and knee pain during performance, each contributed significantly to understanding either speed of movement or self-reported ratings of task difficulty and perceived ability.
