AIMS: Structural equation modelling tested hypothesized causal relationships between age, gender, pain, depression, self-efficacy, outcome expectations, functiol status and quality of life in older Australians postorthopaedics surgery across three stages of their rehabilitation. BACKGROUND: Self-efficacy is important in forming persol beliefs about capabilities to perform functiol activities, which is believed to maintain individual's quality of life. Research examining how efficacy beliefs influence functiol status in older people following orthopaedic events is limited. DESIGN: A descriptive, longitudil method was used for this study. METHODS: A convenience sample of 101 older people with orthopaedic surgery to lower extremities was recruited from private rehabilitation units in Brisbane, Australia. Data were collected from September 2008-November 2009. Standardized questionires were used to measure efficacy beliefs, functiol status, and quality of life. RESULTS: Structural equation modelling revealed that depression, efficacy beliefs, age, and gender significantly influenced quality of life, as self-efficacy and gender have a direct relationship on functiol status. Across three stages in the model, outcome expectation at stage 2 was the most significant predictor of functiol recovery after discharge. Older men with higher quality of life at admission was positively related to self-efficacy and negatively associated with depression at stage 2: quality of life influenced outcome expectations and pain positively at stage 3. CONCLUSION: Rehabilitation programmes play a significant role in assisting older people in resuming functiol activities and quality of life following orthopaedic surgery. Enhancing self-efficacy may facilitate older people's participation and adher-ence to rehabilitation programmes during hospitalization and following discharge.
