Seeking mental health help is a significant step, but that first intake session can often feel more like paperwork than progress, and a significant proportion of people 'drop out' or never return for a second visit, previous research has shown. In a new review investigators confirmed that single-session interventions (SSIs) can significantly improve mental health outcomes in both youth and adults. Common in other countries but not the U.S., an SSI is a structured program intentionally designed to provide meaningful support, guidance or treatment in just one meeting, recognizing that many patients may not return for a follow-up appointment.
