Patients and spouses coping with inflammatory arthritis: Impact of communication and spousal perceived social support and burden

Objectives: To guide Therapeutic Patient Education (TPE) programs to improve patients' and spouses' perceived health, we aimed to analyze the effect of the spouse health state and patient-spouse relationship on functional impairment, mental health and self-efficacy of patients with RA or SpA.

Methods: In this observational cross-sectional study, inclusion criteria were age≥18years and diagnosis of RA or SpA. The outcome criteria were functional impairment and mental health measured by the Medical Outcomes Study Short-Form 12-item version (SF-12-MCS); mental health measured by the General Health Questionnaire (GHQ-12); and self-efficacy by the General Self-Efficacy Scale (GSE Scale). Caregiver-patient relationship was assessed by the Personal Assessment of Intimacy in Relationships (PAIR) questionnaire and the Dyadic Adjustment Scale (DAS); social support by the Social Support Questionnaire-6 and spousal burden by the Zarit questionnaire.

Results: A total of 88 patient-spouse couples were included. Patients were mostly female (n=68, 77%), with mean age 59 (SD 12.6) years; 69% had RA. On bivariate analyses, only spousal burden was associated with patients' functional impairment. Patients' mental health was associated with satisfaction with social support and the dyad relationship. Self-efficacy of patients was associated with spousal burden, satisfaction with social support, spousal anxiety/depression and the dyad relationship. On multivariate analysis, improved mental health and perceived self-efficacy of patients were associated with spousal satisfaction with social support (Beta=0.8, P=0.1 with GHQ-12) good communication in the couple (Beta=0.5, P=0.04 with SF-12-MCS and Beta=0.4, P=0.04 with GSE Scale) and low spousal-assessed burden (Beta=-0.2, P=0.003 with GSE Scale).

Conclusion: This study has identified potential focus for intervention. It has highlighted the importance of recognizing the role of couple communication (experiencing an open and fluent exchange of ideas) in the patient's mental health and self-efficacy but also perceived satisfaction with social support of both members of the couple on the patient's mental health.
