Factors Associated With Dementia‐Related Behaviors Among Caregivers Experiencing Poor Sleep

Abstract

AbstractBackgroundNeuropsychiatric symptoms of dementia are common and have the potential to negatively impact the physical and mental health of family caregivers, hindering their ability to provide care. Such impact may be worse among caregivers experiencing poor sleep. This study aimed to explore factors associated with the frequency of and caregivers’ distress to dementia‐related problematic behaviors.MethodThis was a cross‐sectional study, using data from a clinical trial of dyadic sleep intervention for persons living with dementia (PLWD) and their family caregivers. Dementia‐related behaviors were measured using a 24‐item, Revised Memory and Behavioral Problems Checklist (RMBPC): total scores of frequencies and caregivers’ distress; scores for three subscales (memory‐related, depression, and disruptive behaviors). Caregiver‐related variables included demographic background, Zarit Burden Interview (ZBI), Positive Aspects of Caregiving (PAC), Pittsburgh Sleep Quality Index (PSQI), and Center for Epidemiological Studies of Depression (CESD). Patient‐related variables included activities of daily living (ADLs), instrumental ADLs (IADLs), and Mini‐Mental State Examination (MMSE) scores. A total of 47 dyads were included in the analysis (caregivers: n = 29 spouses, n = 17 non‐spouses; 40% Whites). Pearson correlation analyses were conducted.ResultHigher ZBI and CESD scores were significantly associated with higher RMBPC frequency total (r = 0.41, r = 0.48, respectively; p<0.01) and caregiver distress total scores (r = 0.58, r = 0.43, respectively; p<0.01). Lower PAC (r = ‐0.31, p = 0.04) and higher MMSE scores (r = 0.37, p = 0.03) were also associated with higher caregiver distress total scores. ZBI and CESD scores were associated with RMBPC‐depression subscale scores (frequency/caregiver distress). There were positive associations between CESD and MMSE with RMBPC‐disruptive behaviors (frequency), and ZBI and PAC scores with RMBPC‐disruptive behaviors (caregiver distress). No patient or caregiver‐related factors were associated with RMBPC‐memory subscale scores. There was no significant association between PSQI scores and RMBPC total/subscale scores. Patient factors were not significantly associated with RMBPC frequency total or caregiver distress total scores.ConclusionDementia‐related problems, particularly depressive symptoms and disruptive behaviors of PLWD are associated with both positive and negative aspects of caregiving. Future studies will need to further examine how each RMBPC subscale of behavior contributes to caregiver burden or perceived caregiving experiences among family caregivers.
