title: Older adults' recovery from surgery for osteoarthritis of the knee: psychosocial resources and constraints as predictors of outcomes.
abstract: The authors investigated psychosocial resources (positive support, active coping) and psychosocial constraints (negative support, avoidant coping) as predictors of improvement in the health of 63 older adults undergoing surgery for osteoarthritis of the knee. Following surgery, patients and social partners are motivated both to strive for the appetitive goal of recovery (approach), and to protect themselves from pain and impairment (avoidance). The authors assessed resources and constraints 6 weeks after surgery as predictors of outcomes (improvement in knee pain, knee functioning, and psychological well-being) 6 months after surgery. The constraints patients encountered early in recovery were strong predictors of poor recovery. Although resources were associated with some improvement, these effects were largely accounted for by constraints.
