Abstract: The disclosed methods and systems facilitate and deliver online mental healthcare and other therapeutic services to a group of entities (individuals). First, data associated with the group is received. Second, data are analyzed to generate an entity index for one or more entities and an entity pair index for one or more pairs of entities. Third, the entity indexes and the entity pair indexes are used to generate a group network index. The group network index indicates a level of performance of the group. Fourth, a set of interventions are identified using the group network index in combination with its weighted components, based on weights assigned to entity indexes and entity pair indexes. A set of online therapeutic services is associated with the set of interventions. Fifth, the set of online therapeutic services are executed and delivered.
