OBJECTIVES: To examine whether self-efficacy mediated the effect of the
Home-based Post-Hip Fracture Rehabilitation program on activity limitations in
older adults after hip fracture and whether the mediating effect was different
between sex and age groups. DESIGN: Randomized controlled trial. SETTING:
Community. PARTICIPANTS: Participants with hip fracture (N=232; mean age +/- SD,
79+/-9.4y) were randomly assigned to intervention (n=120, 51.7%) and attention
control (n=112, 48.3%) groups. INTERVENTIONS: The 6-month intervention, the
Home-based Post-Hip Fracture Rehabilitation, is a functionally oriented,
home-based exercise program. Data were collected at baseline, postintervention
(6mo), and follow-up (9mo). MAIN OUTCOME MEASURES: Activity Measure for
Post-Acute Care. RESULTS: The mediating effect of the Home-based Post-Hip
Fracture Rehabilitation program on Basic Mobility function through self-efficacy
for exercise was significant at 9 months (betaindirect=.21). Similarly, the
mediating effect of the intervention on Daily Activity function through
self-efficacy for exercise was significant at 9 months (betaindirect=.49). In
subgroup analyses, the mediating effect was significant at 9 months in the
younger group (age, </=79y) in comparison to the older group and was significant
in women in comparison to men. CONCLUSIONS: Self-efficacy may play a partial
mediating role in the effect on some longer-term functional outcomes in the
Home-based Post-Hip Fracture Rehabilitation intervention. The results suggest
that program components that target self-efficacy should be incorporated in
future hip fracture rehabilitation interventions. Age and sex of the targeted
participants may also need to be considered when developing interventions.
