Existing published studies about health-related quality of life (HRQOL) in caregivers of dementia patients living in Latin American countries are very limited. However, cultural aspects, personal values, and social structure may affect the way caregivers experience their role in different societies. The current study investigated the relationship between HRQOL and psychological factors using a cross-sectional design. The sample consisted of 102 informal caregivers of patients with dementia from Bogotá, Colombia, South America. Measures included the Patient Health Questionnaire (PHQ-9) for depression, the Satisfaction with Life Scale (SWLS), the Zarit Burden Interview, and the Short Health Questionnaire (SF36) for HRQOL. Canonical correlations revealed that there was a significant relationship between caregivers' mental health and HRQOL, such that caregivers with better satisfaction with life and less symptoms of depression had more vitality and better general health. There is a strong relationship between mental health and health-related quality of life in Colombian caregivers of dementia patients living in their country of origin. Specific aspects of mental health, including satisfaction with life and depression, need to be addressed in order to improve caregivers' quality of life. Given that mental health care resources may be scarce in Latin American countries, culturally appropriate interventions should focus on preventing/treating depression and promote life satisfaction, as a way to improve their quality of life.
