Abstract
BACKGROUNDFamily caregivers of people living with dementia can experience feelings of burden and stress but the concept of sense of coherence has been identified as an important protective trait against the negative impact of caregiving. Despite this, there has been no psychometric evaluation of the Sense of Coherence scale-13 with this population. Therefore, a psychometric evaluation was conducted using a mixed-methods approach.METHODFive hundred and eighty-three caregivers of people living with dementia participated in the study. We examined the feasibility, internal consistency, construct validity, floor and ceiling effects, concurrent validity and face validity of the Sense of Coherence scale-13.RESULTSThe Sense of Coherence scale-13 demonstrated adequate internal consistency. Sense of coherence was positively related to resilience, sense of competence and health related quality of life, demonstrating good concurrent validity. However, the face validity of the scale was assessed as poor.CONCLUSIONThe sense of coherence scale performed well under psychometric evaluation however guidance for caregivers should be examined and revised to reflect feedback from caregivers who completed this study, which could lead to improved face validity for this scale.TRIAL REGISTRATION NUMBERISRCTN10748953 .
