Objectives: The study evaluated the efficacy of an internet‐delivered cognitive‐behavioral intervention for caregivers of people with dementia and examined acceptance of program characteristics. Method: Thirty‐nine caregivers (Mage = 62.11 ± 9.67, 78.4% female) were enrolled in a 2 × 3 randomized‐controlled trial (RCT) that compared an intervention and wait‐list control group. A cognitive‐behavioral intervention program was adapted for delivery via an internet platform. Participants exchanged eight weekly messages with a therapist.
