Women who use hormonal contraception only have a greater accuracy and response bias for sad expressions, which can be linked to depression symptoms and diagnoses. It was hypothesized that women who use hormonal contraception have a larger AB towards negative emotions in comparison to naturally cycling women. Healthy female volunteers (N=266) participated in an online AB task, the emotional dot-probe task including the facial expressions: neutral, angry, happy, and fearful faces. Additionally, the participants filled in the DASS-21 questionnaire, where this study utilized the depression subscale. AB was quantified as the difference between reaction times to incongruent and congruent trials. A significant AB was found in this online set-up. The naturally cycling women group showed a stronger AB in comparison to the hormonal contraception users. This effect was independent of emotion. Even though no significant effect of depression was found and no correlation between AB and depression was found, there was a trend for the naturally cycling women group to score higher on depressive symptoms, which may contribute to the higher AB in this group. The contradictory results may be clarified by the fact that, compared to naturally cycling women, hormonal contraception users experience less variation in mood during the menstrual cycle and there is less negative mood throughout the menstrual period. By comparing these groups, these findings contribute to increasing evidence of research examining the use of hormonal contraception and the influence it may have on mood.Show less
