Background: This study examines the psychometric properties of the Dysfunctional Thoughts about Caregiving Questionnaire (DTCQ).
Methods: DTCQ was administered to 227 dementia family caregivers.
Results: Principal components analyses resulted in a two-factor solution: Perception of Sole Responsibility and Perfectionism. The DTCQ has a strong internal consistency and an adequate temporal stability. The DTCQ score differentiated between depressed and non-depressed caregivers, although only in the female group. Construct validity was also supported by significant relationships between DTCQ scores and global dysfunctional attitudes, social support, seeking social support and number of hours per day engaged in caring. The dysfunctional thoughts about caregiving specify rigid and inappropriate contingencies to guide and assess behavior while acting as cognitive barriers that make healthy care difficult.
Conclusion: The results of this study showed that such dysfunctional thoughts have a significant relationship to variables identified as mediators in caregiving stress models. The DTCQ has potential uses for both research and clinical purposes.
