Factor Analysis- Statistical

Introduction: To examine the psychometric properties of different short versions of the Zarit Burden Interview (ZBI), and to find an efficient and valid short version for clinical use among dementia caregivers.; Materials and Methods: A total of 270 Taiwanese dementia caregivers filled out the full form of the ZBI, which contains 22 items. Using the 22-item ZBI, we used confirmatory factor analysis (CFA) to calculate the fit indices of all proposed short versions with various items to determine useful short versions.

Background: The study is aimed at developing a new measure devised to evaluate gains associated with caregiving for a person with dementia.; Methods: We conducted two studies with Spanish informal caregivers. In Study 1 a total of 152 participants responded to a preliminary set of 62 items referred to gains related with caregiving.
