Purpose: The Mutuality Scale is composed of 4 theoretically derived factors (love, shared pleasure activities, shared values and reciprocity) but this structure has never been confirmed. Also, research involving the patient’s perspective on the Mutuality Scale is limited. In this study we tested the factorial structure of the Mutuality Scale and its reliability in stroke caregivers and patients. Design and Method: cross-sectional, with a follow up after 15 days for test-retest reliability. 163 stroke caregivers and 248 stroke patients completed the Mutuality Scale. Stroke patients and their caregiver were enrolled in ten rehabilitation hospital across Italy. Mutuality Scale factorial structure was analyzed with Confirmatory Factor Analysis; internal consistency reliability was evaluated with Cronbach’s alpha and model-based internal consistency index; test-retest reliability was evaluated with intraclass correlation coefficient. Results: Confirmatory Factor Analysis supported the four factor structure of Mutuality Scale in its caregiver and patient version (CFI=0.94 and RMSEA 0.06 for both). Cronbach’s alphas and modelbased internal consistency index were > 0.90 and Intraclass Correlation ranges between 0.66 to 0.93 in Mutuality Scale caregiver and patient version. Implication: This study tested the theoretical dimensions of the Mutuality Scale in stroke caregivers and patients. From a scientific and clinical point of view, an assessment of stroke caregiver and patient mutuality would allow dyadic approaches to data analysis and care that account for the non-indipendence between the stroke caregiver and the patient

Abstract
Purpose: The Mutuality Scale is composed of 4 theoretically derived factors (love, shared pleasure activities, shared values and reciprocity) but this structure has never been confirmed. Also, research involving the patient’s perspective on the Mutuality Scale is limited. In this study we tested the factorial structure of the Mutuality Scale and its reliability in stroke caregivers and patients. Design and Method: cross-sectional, with a follow up after 15 days for test-retest reliability. 163 stroke caregivers and 248 stroke patients completed the Mutuality Scale. Stroke patients and their caregiver were enrolled in ten rehabilitation hospital across Italy. Mutuality Scale factorial structure was analyzed with Confirmatory Factor Analysis; internal consistency reliability was evaluated with Cronbach’s alpha and model-based internal consistency index; test-retest reliability was evaluated with intraclass correlation coefficient.
