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.
