Abstract

Objective: To evaluate the psychometric characteristics of the Caregiver Preparedness Scale (CPS) in caregivers of stroke survivors.

Background: Caregiver 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.

Methods: We 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.

Results: Caregivers 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.

Conclusion: The 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.
