title: [Differences between adolescents with pathological Internet use in inpatient and outpatient treatment].
abstract: In epidemiological studies high prevalence estimates for pathological Internet use in adolescence were reported. There are only few studies published, reporting data of adolescents seeking treatment concerning their pathological Internet use. Currently, a comparison of patients in inpatient versus outpatient treatment is not available.
  
  
  
  We investigated 74 adolescents reporting pathological Internet use with standardized questionnaires concerning problematic Internet use, psychopathological symptoms and life satisfaction. Overall, 35 adolescents were treated in an outpatient and another 39 adolescents in an inpatient setting.
  
  
  
  A substantial portion in both groups showed comorbid mental health problems. There were no differences in the degree of problematic Internet use between the two groups. However, compared to adolescents in an outpatient setting, adolescents in inpatient treatment reported longer average Internet usage times, a lower life satisfaction as well as more anxiety/depressiveness and self-esteem problems. In a multivariate logistic regression analysis Internet usage time and life satisfaction were identified as statistically significant factors for the affiliation to one of the two treatment groups.
  
  
  
  The results of the present study could be useful as a further description of this group of patients and more general to develop interventions for adolescents reporting pathological Internet use.
