رابطه بین هورمون های استروئیدی جنسی و بازداری رفتاری (BIS) و فعال سازی رفتاری (BAS) در پسران و دختران نوجوان

This paper analyses the association between free testosterone (FT), free estradiol (FE2) and Carver and White’s (1994) four-factor model of behavioural inhibition (BIS) and behavioural activation (BAS) within a sample of adolescent boys (N = 301, mean age: 14.4 years) and girls (N = 298, mean age: 14.3 years). No direct relationship between FT and BIS or BAS was found in either boys or girls. An association between FE2 and BAS-fun was found in boys and in girls. In addition, with respect to girls, interaction-effects were found indicating a positive association between FE2 and BAS-drive and a negative association between FT and BAS-fun depending on menstrual cycle phase.
