Abstract
ObjectiveTo evaluate the psychometric characteristics of the Caregiver Preparedness Scale (CPS) in caregivers of stroke survivors. BackgroundCaregiver preparedness can have an important impact on both the caregiver and the stroke survivor. The validity and reliability of the CPS has not been tested for the stroke-caregiver population. MethodsWe used a cross-sectional design to study a sample of 156 caregivers of stroke survivors. Construct validity of the CPS was evaluated by confirmatory factor analysis (CFA). Internal consistency and test-retest reliability were also evaluated. ResultsCaregivers were, on average, 54 year old (SD = 13.2) and most were women (64.7%). CFA supported the unidimensionality of the scale (comparative fit index = 0.98). Reliability was also supported: item-reliability index and item–total correlations above 0.30; composite reliability index = 0.93; Cronbach's alpha = 0.94; factor score determinacy = 0.97; and test-retest reliability = 0.92. ConclusionThe CPS is valid and reliable in caregivers of stroke survivors. Scores on this scale may assist health-care providers in identifying caregivers with less preparedness to provide specific interventions.
