Abstract
Objectives: To develop and test preliminary reliability and validity of a Self-Efficacy Questionnaire for Chinese Family Caregivers (SEQCFC).
Methods: A cross-sectional survey of 196 family caregivers (CGs) of people with dementia (CGs) was conducted to determine the factor structure of a SEQCFC of people with dementia. Following factor analyses, preliminary testing was performed, including internal consistency, 4-week test-retest reliability, and construct and convergent validity.
Results: Factor analyses with direct oblimin rotation were performed. Eight items were removed and five subscales (self-efficacy for gathering information about treatment, symptoms and health care; obtaining support; responding to behaviour disturbances; managing household, personal and medical care; and managing distress associated with caregiving) were identified. The Cronbach's alpha coefficients for the whole scale and for each subscale were all over 0.80. The 4-week test-retest reliabilities for the whole scale and for each subscale ranged from 0.64 to 0.85. The convergent validity was acceptable.
Conclusions: Evidence for the preliminary testing of the SEQCFC was encouraging. A future follow-up study using confirmatory factor analysis with a new sample from different recruitment centres in Shanghai will be conducted. Future psychometric property testings of the questionnaire will be required for CGs from other regions of mainland China.
