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

Background Neuropsychiatric 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. Method This 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. Result Higher ZBI and CESD scores were significantly associated with higher RMBPC frequency total (r = 0.41, r = 0.48, respectively; p
