The Caregiver Thoughts Scale: An Instru...

Objectives: Caregivers' care-related thoughts critically effect their well-being. Currently, there is a lack of validated measures to systematically assess caregivers' functional and dysfunctional thoughts. We therefore aimed to develop a measure of caregivers' thoughts that assesses not only their dysfunctional but also their functional thoughts in multiple domains.

Methods: A pool of potential questionnaire items was generated from therapy sessions with caregivers and was rated by experts. A sample of 322 main family caregivers (M_age = 63.9 years) of a person with dementia then completed a set of 28 items about their care-related thoughts and a number of related measures at three measurement points. Items were then aggregated via a formative measurement approach based on theoretical considerations. Correlational analyses were used to examine the construct validity of the subscale scores.

Results: The final 28-item scale assesses caregiving thoughts in four distinct domains: dysfunctional caregiving standards, self-care, dysfunctional assumptions about dementia, and acceptance. The correlational analyses demonstrated the subscales' construct validity, by showing that scale scores are meaningfully related to theoretically relevant constructs.

Conclusions: The Caregiving Thoughts Scale is a promising measure of caregivers' thoughts in four important domains.

Clinical implications: The scale can be applied in clinical research settings.
