The authors tested whether self-efficacy for orthopedic rehabilitation tasks accounted for significant variance in rehabilitation outcome, over the variance accounted for by dispositional optimism, health competence, and health value. Whether health value moderated expectancy-outcome relationships also was examined. One hundred five older clients at 2 orthopedic rehabilitation facilities completed a battery of instruments; physical functioning also was assessed. After controlling for physical functioning at admission and for other variables, self-efficacy predicted significant variance in rehabilitation outcome. Health value did not moderate expectancy-outcome relationships. Results suggest that psychologists can improve patients' recovery from serious orthopedic problems by augmenting their self-efficacy beliefs.Orthopedic injury is a major health care concern in the United States for persons 65 years old and older. For example, approximately 250,000 persons are hospitalized each year for treatment of a fractured hip. Risk factors include age, gender, race, medication use, and mental distress (Allegrante, MacKenzie, Robbins, & Cornell, 1991;Forsen et al., 1999). In addition to fall-related orthopedic injuries, elderly persons also require orthopedic surgery for degenerative joint disease of the hip or knee (Orbell, Espley, Johnston, & Rowley, 1998). National health care costs from orthopedic injuries exceed $7 billion per year (Allegrante et al., 1991), and up to 60% of orthopedic patients face postsurgery complications including loss of functional capacity and independence, with many patients requiring long-term institutional care.In an attempt to ameliorate the negative effects of orthopedic surgery and aid rehabilitation, psychologists have begun to focus on psychological factors that affect the disabled patient's condition, including thoughts, beliefs, and attitudes (Bloom, 1988). Broad beliefs such as dispositional optimism (Scheier & Carver, 1985), moderately broad beliefs such as perceived health competence (Wallston, 1991), and more specific beliefs such as selfefficacy expectancies (SE; Bandura, 1997) all have predicted important outcomes among disabled persons or other populations. However, no study has examined these beliefs as predictors of rehabilitation following orthopedic surgery. Studying positive beliefs and their relationship to health-related outcomes is consistent with counseling psychology's emphasis on psychological assets and positive facets of growth (Fretz, 1982;Gelso & Fretz, 1992).
