Optimising an Online Self-help Program for Coping With the Loss of a Spouse

SOLENA follows the most relevant CBT elements of interventions for prolonged grief: 1) Exposure, e.g., telling the story of the loss; 2) cognitive reappraisal or restructuring of individual dysfunctional thoughts associated with the loss; 3) integration and restoration including self-care and social reengagement; and 4) behavioural activation. SOLENA's content is provided through a conversational virtual agent, Sol, who guides the user through the Study section the CBT intervention itself. In 10 study modules that address either the acceptance of the loss or the restoration and adaptation to a new life, SOLENA includes 1) readings, i.e., texts based about grief related topics that provide the background and rational for the module; and 2) exercises to encourage mourners to actively reflect on their grief and apply their new knowledge to their daily life and to practise the new routines regularly. SOLENA also provides users with the Notebook, Activities, and My Support sections.
