title: Differential modulation of impulsive behavior by loneliness and testosterone in adolescent females.
abstract: OBJECTIVE
  Adolescence is characterized by increases in loneliness, impulsiveness and circulating testosterone levels. We investigated the relationship between these characteristics in adolescent females.
  
  
  METHODS
  For this purpose, we measured impulsivity and loneliness by means of a Go/No-go task and the UCLA loneliness scale, respectively. Testosterone levels in saliva were measured by Enzyme-Linked Immunosorbent Assay (ELISA).
  
  
  RESULTS
  The results showed that testosterone and loneliness have a positive relevance to impulsivity in adolescent females, whereas there was no relationship between loneliness and testosterone levels.
  
  
  CONCLUSIONS
  These results suggest that testosterone and loneliness modulate impulsivity via distinctive pathways.
