This study aims to examine the role of interoceptive abilities in the use of emotion regulation strategies and the success of emotion regulation in regulating the negative mood in healthy individuals. First, it is expected that better interoceptive functioning (namely, higher interoceptive accuracy and interoceptive sensibility) will facilitate the use of adaptive emotion regulation strategies (vs. maladaptive emotion regulation strategies) to regulate the negative mood. In addition, it is expected that individuals with greater interoceptive abilities will show greater efficacy in the emotion regulation process (i.e., greater reduction of negative mood after the emotion regulation task) than individuals with lower interoceptive abilities. However, it is hypothesized that interoceptive abilities will not be related to the induced negative affect.
The whole study is conducted in one single 1-hour session. First, participants will be screened to check eligibility inclusion/exclusion criteria. Second, eligible participants will complete baseline measures, namely, trait emotion regulation abilities and interoceptive abilities. Third, participants will complete a mood rating scale, after which they will be applied a negative mood induction procedure (MIP) that has previously been shown to effectively induce sadness. During this MIP, the heart rate variability will be recorded. Next, participants will complete the mood rating scale again. Later, they will perform a spontaneous emotion regulation task. In this task, participants will have 2 min to do, say, and/or think about whatever they need to feel better. Afterwards, participants will again rate their mood and complete the final measures regarding state emotion regulation. Finally, participants will receive a positive MIP (while recording their heart rate variability) and be debriefed. The study will be conducted following the principles stated in the Declaration of Helsinki.
