- The caregiver-care receiver relationship (mutuality) in Parkinson’s disease (PD) and its association with motor and non-motors symptoms, health-related quality of life (HRQoL), and caregiver burden have not fully been investigated. The aim of our study was to explore if (1) the level of mutuality perceived by PD-patients and PD-partners differs, (2) different factors are associated with perceived mutuality by PD-patients and PD-partners, and (3) mutuality is associated with PD-patients health-related quality of life (HRQoL) and caregiver burden. We collected data on motor signs (UPDRS III), non-motor manifestations (NMSQuest), PD-patients’ cognition (IQCODE), mutuality scale (MS), PD-patients’ HRQoL (PDQ8), and caregiver burden (CB) from 51 PD dyads. Predictors were identified using multivariate regression analyses. Overall, the dyads rated their own mutuality as high with no significant difference between the dyads except for the dimension of reciprocity. PD-patients’ MS score (p=.001) and NMSQuest (p≤ .001) were significant predictors of PDQ8. Strongest predictor of CB was PD-partners’ MS score (<.001) and IQCODE (p=.050). In general, it seems that non-motor symptoms contribute to a larger extent to the mutual relationship in PD-affected dyads than motor disabilities.

- The relationship quality, mutuality, has been identified as a protective factor in family care situations, but its role in mediating health-related quality of life (HRQoL) in patients having Parkinson’s disease (PD) is not known. Data on patients’ and partners’ mutuality (MS), motor signs (UPDRS III), non-motor symptoms (NMSQuest), impaired cognition (IQCODE), dependency in activities of daily life (ADL), and HRQoL (PDQ8) were collected from 51 dyads. Structural equation model with manifest variables was applied to explore if the MS score mediated the effect of UPDRS III, NMSQuest, IQCODE, and dependency in ADL on PDQ8. The results suggest that increasing severity of motor and non-motor symptoms decreases patients’ mutuality which leads to worse HRQoL. Partners’ mutuality mediated the effect of impaired cognition which in turn decreased patients’ mutuality. The findings enhance our understanding of how various symptoms may influence PD patients’ HRQoL. This may help clinicians to personalize interventions to provide more effective interventions to improve the lives of patients with PD.

- OBJECTIVES: The 15-item mutuality scale (MS) has been used in several neurological conditions assessing the quality of relationship associations with negative effects of the caregiving situation. The aim of this study was to translate the original MS into Swedish and assess its psychometric properties in Parkinson's disease (PD).MATERIALS AND METHODS: Following the forward-backward translation method, the scale was evaluated regarding linguistic correctness at a conceptual level and user-friendliness. The scale was filled out by a sample of 50 care dyads where one was having PD. Scale assumptions and scale structure were evaluated using floor/ceiling effect and principal component analyses (PCA) with promax rotation. Internal consistency was evaluated using Cronbach's alpha and mean inter-item correlation coefficients.RESULTS: The Swedish MS was evaluated as user-friendly and relevant by the participants. The scale demonstrated no floor/ceiling effect and showed high internal consistency (α≥0.93) with a mean inter-item correlation coefficient of ≥0.5. Through the PCA, a two factor solution emerged, which accounted for 67% and 64% of the variance of the MS score by PD-partners and PD-patients, respectively. However, some variables were complex and discarded in the final solution.CONCLUSION: Our findings provide initial support of the Swedish MS as a user-friendly and useful instrument with acceptable psychometric properties even though more research is needed to evaluate the existence of subscales.
