The present study compared immigrant and Italian native adolescents with regard to drug use. Additionally, we analysed the role of family and peer risk and protective factors for drug use. Participants included 2533 Italian native and immigrant adolescents (mean age = 17.19, SD = 1.6; 66.7% male). Results showed that immigrant adolescents reported lower levels of marijuana and pharmaceutical drug abuse than non‐immigrant adolescents. These results confirm the so‐called immigrant paradox phenomenon: the counterintuitive finding that although immigrants often live under challenging conditions and reported lower economic affluence compared with nationals, some health outcomes have not always corresponded to their relative disadvantage. Immigrant adolescents also reported higher level of parental control and lower levels of affiliation with deviant peers, but lower levels of child disclosure, parental solicitation and parental knowledge. Socio‐economic status and parental monitoring showed equivalent effects on drug use for immigrant and non‐immigrant adolescents. Results have implications for preventive interventions for immigrant adolescents and families, including the need to develop programmes that leverage the benefits of the immigrant paradox for immigrant communities. Future research should analyse the processes that lead to lower levels of drug use in immigrant adolescents and investigate the influence of friendship networks on immigrant adolescent drug use behaviour.

Violence and interpersonal aggression are considered major public health problems throughout the world. Yet there is considerable variability in how these terms are operationalized, measured, and studied in the social sciences, which can lead to ambiguity and confusion in the field. In this introduction to the special issue, the authors highlight some of the difficulties inherent in studying interpersonal aggression and violence and briefly review the heterogeneous nature of the research conducted in this area. The authors conclude with a summary of the key findings of the articles that appear in this special issue. 相似文献

Uncontrollable episodes of emotional expression occur in a variety of neurological conditions. This emotional disinhibition syndrome is characterized by episodes of crying or laughing that are unrelated to or out of proportion to the eliciting stimulus. This syndrome is common among patients with amyotrophic lateral sclerosis, multiple sclerosis, stroke, and traumatic brain injury and a variety of terms and definitions have been used to describe it. The confusing nomenclature has been a barrier to understanding, diagnosis, and treatment of this disorder. The authors propose a unifying term, involuntary emotional expression disorder (IEED), and provide diagnostic criteria for this disorder. 相似文献
