Abstract
<title>Abstract</title> <p> Background Caregivers help manage the behavioral and psychological symptoms that people living with dementia experience. However, caregivers’ knowledge is imperfect, and available resources (e.g., online webpages) can promote low-quality learning that is ineffective. Objectives We evaluated an evidence-based, self-guided, digital learning intervention aimed at improving caregivers’ knowledge and long-term retention of dementia care information. Methods A pre-registered, randomized-controlled experiment was conducted with 64 caregivers of people living with dementia. Caregivers learned about managing symptoms of dementia via practice testing with detailed, corrective feedback, which was contrasted against two active control comparisons – practice testing without feedback and rereading. Results Practice testing with detailed, corrective feedback intervention enhanced immediate learning and knowledge on a 2-day delayed test relative to both active control comparison conditions. Benefits of the digital intervention were observed on a 1-year-delayed test relative to the re-read active control comparison. Caregivers rated this intervention favorably. Conclusions Practice testing with detailed, corrective feedback is an effective intervention for targeting caregivers’ dementia-related knowledge. Psychoeducational interventions should implement testing with feedback. Trial Registration: ClinicalTrials.gov, <bold>NCT07377318</bold> . </p>
