Family Dynamics in Dementia Caregiving: Development and Validation of the Interpersonal Triggers of Guilt in Dementia Caregiving Questionnaire (ITGDCQ).

The objective was to develop the Interpersonal Triggers of Guilt in Dementia Caregiving Questionnaire (ITGDCQ). An emotion frequently experienced by caregivers is guilt. However, the studies analyzing potential factors that generate guilt are scarce. Guilt may be generated through interpersonal interactions. A total of 201 dementia caregivers were evaluated for frequency of leisure, guilt, anxiety, depression, and a pool of items measuring the frequency, and guilt was derived from different behaviors performed by the care recipient (ITGDCQ-CR) and other relatives (ITGDCQ-OR). Exploratory factor analysis of the ITGDCQ-CR showed a two-factor solution, explaining 56.24% of the variance. The ITGDCQ-OR subscale also showed two factors, explaining 63.24% of the variance. All the factors had acceptable to good reliability indexes. Positive associations were found between both subscales and depression, anxiety, guilt, and stress associated with CR's behavioral problems. ITGDCQ-CR was negatively correlated with frequency of leisure. The interpersonal dynamics assessed with the ITGDCQ generated other emotions such as anger or sadness. Through structural equation modeling, 28% of the variance of caregivers' distress was explained by the assessed variables, including a significant contribution of the interpersonal dynamics assessed with the ITGDCQ. The results provide preliminary support for the use of the ITGDCQ as a valid and reliable measure of care recipients' or other relatives' factors that trigger or facilitate the experience of guilt in the caregivers. The association between these factors and caregiver distress suggests potential clinical implications for the findings.
