Editorial Perspective: Effective mental health and psychosocial interventions for children and adolescents in street situations.

Children and adolescents in street situations (CASS) in low- and middle-income countries (LAMIC) could arguably be regarded as the most at-risk group of children for mental health and psychosocial impairments compared with any other group of children. CASS, street-connected children and street children are some of the terms used to describe this group of children who have some association with the street; such as living, working or loitering for long periods of time on the street. These children are often described as 'voiceless'; a vulnerable group of children who experience a considerable amount of adversity from a young age.
