Psychosocial factors affected by burden in family caregivers of people with Alzheimer's disease.

The world's population is experiencing an aging process, which is resulting in an increase in diseases such as Alzheimer's disease. Consequently, more and more people need care, which can lead to overload and harm to their family's quality of life.

Objective: Identify the psychosocial factors affected by the burden on family caregivers of people with Alzheimer's disease.

Methods: Forty-nine family caregivers of people with Alzheimer's disease, from a city in Minas Gerais, Brazil, participated in the study. They filled out a form of sociodemographic variables, and answered the Burden Interview Scale (BI-Zarit), Quality of Life in Alzheimer's Disease Caregiver version (CQoL-AD), the Depression, Anxiety and Stress Scale (DASS-21), the Mindfulness and Awareness Scale (MAAS) and the Clinical Dementia Rating Scale (CDR).

Results: All participants were female with an average age of 54.26 (±8.99). Daughters comprised 77.55% of the sample, and 34.69% were sole caregivers. The Bi-Zarit scale positively and significantly correlated with DASS-21 Depression (r=0.440; p=0.002), DASS-21 Anxiety (r=0.415; p=0.003), DAAS-21 Stress (r=0.583; p<0.001). On the other hand, it showed a negative correlation with MAAS (r=-0.429; p=0.002) and CQoL-AD (r=-0.533; p<0.001).

Conclusion: This study demonstrates that family caregivers of people with Alzheimer's disease may be overloaded, and that the heavier the burden, the lower level of attention, the worse quality of life and the greater the possibility for the caretaker to present symptoms of depression, anxiety, and stress.
