Spain is the second country in the world in numbers of missing people, with 114,226 men and women still in mass graves without having been identified and buried by their relatives. Added to them are the families of stolen babies: 300,000 babies were stolen during and after Franco's dictatorship. Faced with these disappearances, a digital health intervention (DHI) for the accompaniment and monitoring of the process of mourning and trauma recovery could improve the situation of this extensive and diverse population, situated throughout Spain. Limitations in resources for the care and accompaniment of this population are due to various logistical, geographical, financial, stigmatic, and demographic factors—this is an ageing population—preventing them from accessing places of treatment. In this chapter, the author proposes a health app for trauma recovery that can be readily standardized for the wide dissemination of evidence-based care and adapted to the needs of this specific population.
