Workshops are typically short educational courses that focus on specific concepts in a particular course of study, or on the development of a particular skill. Workshops on mental health are often informal and interactive. Trainers and participants may take part in discussions, presentations, debates, or hands-on demonstrations to engage with new ideas and techniques. Workshops are also time-limited and self-contained. While many academic courses may take months to complete, a typical workshop for therapists, psychologists, clinical social workers, or the general public may last from only 1 hour up to several days.
