Caring for an older adult who needs help or supervision is in many cases associated with mental and physical health issues, especially if the care recipient has dementia, although positive consequences associated with caregiving have also been reported. Several theoretical models have shown the relevance of psychological variables for understanding variations in the stress process associated with caregiving and how interventions may benefit from psychological techniques and procedures. Since the 1990s it has been witnessed an increment in the number of studies aimed at analyzing caregiver health and developing and testing interventions for decreasing caregiver distress. Several examples of interventions for helping caregivers are considered empirically supported, including interventions for ethnically and culturally diverse caregivers, with psychotherapeutic and psychoeducational interventions showing strong effect sizes. However, efforts are still needed to maintain the results of the interventions in the long term and to make the interventions accessible (e.g., through technological resources) to a large number of caregivers who, because of time-pressure issues associated with caregiving or a lack of support, are not benefiting from them. Making these interventions available in routine healthcare settings would help a large population in need that presents with high levels of psychological suffering.
