Mechanisms Underlying the Use of Abusive and Neglectful Behaviors in Dementia Caregiving: The Role of Caregiver Mental Health.

Purpose: In dementia family caregiving, caregiver psychopathology has been frequently identified as a possible risk factor for the use of physically abusive, psychologically abusive, and neglectful behaviors toward care recipients. Yet, the mechanistic role of psychopathology in the use of these behaviors is not understood. The purpose of the current study is to determine the role of caregiver mental health in their daily risk of engaging in physically and psychologically aggressive and neglectful behaviors toward their care recipient with dementia.

Method: We used an intensive longitudinal design to survey family caregivers daily over 21 days. Using generalized linear mixed models, we evaluated the differential impact of caregivers' (N = 453) experience of major depression and generalized anxiety disorders measured at baseline versus 9,513 daily ratings of depressive and anxiety symptom severity, and interactions across levels, on the daily odds of engaging in physically abusive, psychologically abusive, and neglectful behaviors.

Results: Caregivers with clinically significant depression or anxiety at baseline had higher daily odds of engaging in each type of abusive and neglectful behavior. Worsened depressive symptoms (compared to individuals' average across all days) on a given day were associated with increased odds of engaging in psychologically and physically aggressive behaviors on the same day. Worsened anxiety symptoms on a given day were associated with increased odds of psychologically aggressive and neglectful behaviors.

Conclusion: A key finding was lack of a significant interaction effect between depression and anxiety disorders and mental health symptomology on the daily odds of engaging in abusive and neglectful behaviors. This finding indicates that daily depressive and anxiety symptoms are generalizable intervention targets across the family caregiver population and do not only increase risk among family caregivers with depressive and anxiety disorders.
