Long-term effects of telephone-based cognitive-behavioral intervention for family caregivers of people with dementia: Findings at 3-year follow-up.

Tele.TAnDem is successful in buffering detrimental effects of caregiving on caregiver burden and social relationships in the long term. The small- to medium-sized effects lie in the range of effect sizes reported in the few previous investigations. The findings add to the scant evidence that interventions yielding long-term outcomes have to date mostly been multicomponent interventions based on CBT principles with structured techniques and at least seven sessions over more than 2 months.
