Spouses' use of pressure and persuasion to promote osteoarthritis patients' medical adherence after orthopedic surgery.

Objective: The authors investigated health-related effects of social control (influence) that spouses exert in relation to osteoarthritis patients' medical adherence after total knee replacement surgery. Patients' behavioral and emotional responses to control were examined as mediators of associations between spouses' use of two control strategies (pressure, persuasion) and patients' physical and psychological recovery.

Design: The authors used a three-wave panel design with assessments at one month before surgery, 1 month and 3 months after surgery. Data were collected during in-person interviews with 70 married, older adult patients.

Main Outcome Measures: Recovery outcomes were assessed as improvement in knee limitations and depressive symptoms at the 3 month follow-up.

Results: Spousal pressure and persuasion at one month postsurgery were indirectly associated with patients' recovery outcomes through patients' positive emotional responses to control.

Conclusion: Although there are often immediate behavioral benefits in response to partners' use of both pressure and persuasion, the long-term health effects of these strategies seem to be accounted for by their opposing links to positive emotions. Findings further refine theory on health-related social control in marriage.
