Interconnectedness through technology presents both challenges and opportunities for suicide prevention and intervention with adolescents and families. The time following discharge from acute care facilities represents a critical period of suicide risk for adolescents, which could be buffered by a technological intervention they could use post-discharge. Crisis Care is a smartphone application intervention developed specifically for suicidal adolescents and their parents to use during this period of increased risk. A web-based prototype of Crisis Care was pilot tested with 20 adolescent-parent dyads. Results demonstrated acceptability and usability, suggesting the utility of technological interventions, such as Crisis Care, as an adjunct to treatment for suicidal adolescents and their parents following discharge from acute care settings.
