Parkinson’s disease and factors influencing the quality of the dyadic relationship

Objectives: The aim of this project is to explore how the quality of the dyadic relationship (mutuality) is affected by motor and non-motor symptoms, other perceived difficulties and quality of life (HRQoL) when one person in the dyad is having Parkinson´s disease (PD). Methods: Fifty dyads (age m=70.5[SD=8.5], PD-duration m=8.6[SD=6.6], Hoehn & Yahr md=2[IQR=1]) completed validated scales measuring mutuality (MS), caregiver burden (CB), caring difficulties (CADI), depression (GDS) and HRQoL (PDQ8). Spearman´s correlations were used to evaluate univariate associations. To investigate multivariate associations between independent factors and mutuality, multiple regression analysis was used. Results: Partner mutuality score was significantly associated with CB (rho=-0.69), CADI (rho=-0.61), partner GDS (rho=-0.52), patient MS (rho=0.49), patient GDS (rho=-0.42), and PDQ8 (rho=-0.38). Partner mutuality score did not strongly correlate with motor (rho=-0.24) and non-motor symptoms (rho=-0.24) or disease duration (rho=-0.11). Instead CADI, GDS, PDQ8, CB and patient MS score explained 62 % of the variance in partner mutuality. Of the included variables CADI and patient MS score showed the largest contribution (standardized beta=-0.43, p =.043 vs beta=0.35, p=0.005). Conclusion: Findings suggest that higher experience of carer difficulties and patient experience of mutuality may exert an effect on partner mutuality in care-dyads with mild to moderate PD. This ongoing longitudinal study aims now to explore how the course of PD affects mutuality, CB and HRQoL from the perspective of the care-dyad.
