For students, practitioners, and educators, Laser and Nicotera (social work, U. of Denver) detail how to work with adolescents who are having difficulties. Social work and other researchers from the US address protective and risk factors and resilience; the importance of a multisystematic-ecological approach in understanding adolescent development, which takes into account different contexts and sociopolitical factors; how this approach is applicable to different practice settings; individual, family, peer, school, neighborhood, and media influences on development; and interventions for specific challenges like substance abuse, sexual identity issues, mental health problems like depression and suicidal behavior, risky sexual behavior, and delinquency.
