Spouse-caregivers' quality of life in Alzheimer's disease

Background: The relationship between sexuality and quality of life (QoL) of spouse-caregivers remains unclear. We designed this study to evaluate the relationship between sexual satisfaction and spouse-caregivers' QoL, and to determine the influence of the clinical characteristics of people with dementia (PWD) on spouse-caregivers' self-reported QoL. Methods: Using a cross-sectional design, 54 PWD and their spouse-caregivers completed the QoL in Alzheimer's Disease scale (QoL-AD), questionnaire on sexual experience and satisfaction (QSES), Mini-Mental State Examination (MMSE), Clinical Dementia Rating scale (CDR), Assessment Scale of Psychosocial Impact of the Diagnosis of Dementia (ASPIDD), Pfeffer functional activities questionnaire (FAQ), the Cornell scale for depression in dementia (CSDD) and Zarit burden interview (ZBI). Univariate and multivariate regression analyses were conducted to identify the factors that influenced the spouse-caregivers' QoL ratings. Results: We did not find a significant difference in QoL between male and female spouse-caregivers (p = 0.71). We also found that 13% of males and 48.1% of females demonstrated moderate to severe sexual dissatisfaction. However, we did not find a significant correlation between spouse-caregivers' QoL and sexual satisfaction (p = 0.41). The linear regression indicated that impaired awareness and lower QoL of PWD were significantly related to spouse-caregivers' QoL (p = 0.000). Conclusions: The spouse-caregivers' QoL is influenced by awareness of disease and PWD QoL. Our study would be helpful for the development of adequate psycho-educational approaches to increase spouse-caregivers' QoL, considering the specificities of the couples' relationship.
