A multi-centre, randomized, 3-month study to evaluate the efficacy of a smartphone app to increase caregiver's positive mental health

To assess the effectiveness of a smartphone app-based intervention compared to a regular intervention of caregivers in primary health care institutions. The intervention is aimed at increasing positive mental health and decreasing caregiver's burden. Randomized and controlled trial with an experimental group and a control group. 108 caregivers over 18, with a minimum of 4 months of experience as caregivers. Description of the intervention: an intervention with a smartphone app (n = 54) or a regular intervention for caregivers (n = 54). Each caregiver installs a smartphone app and uses it for 28 days. This app offers them a daily activity (Monday-Friday). These activities are related to the Decalogue of Positive Mental Health, which was designed ad hoc by a group of experts. The outcomes will be the score of caregiver burden, the positive mental health and participant satisfaction. These results will be assessed after the first, third and sixth month. The results of this study will offer evidence of the effectiveness of an intervention using a free smartphone app. If its effectiveness is proven and the results are acceptable, this could lead to a rethinking of the intervention offered to caregivers in primary care.
