Influence Of Emotion Regulation Strategies On Risk Decision Of Students With Subthreshold Depression Under Different Emotional States

Subthreshold depression(SD)refers to a state between health and depression that contains some depressive symptoms but does not fully meet the clinical diagnostic criteria for depression.Many schools pay more attention to students with depression,but do not understand and pay enough attention to people with subthreshold depression,if their groups are not timely and effective intervention,it will be very likely to develop depression.Risk decision-making is an important cognitive activity in people's daily life.When people make a certain decision,they are vulnerable to some factors,especially emotional factors,and make wrong decisions in decision-making.Therefore,choosing appropriate and effective emotion regulation strategies can help students with subthreshold depression to better regulate their emotions and minimize the negative effects of emotional factors on risk decision-making behavior.In this study,two experiments were used to explore in depth the impact of these factors on the risk decision-making of Subthreshold depression universities and the interaction between different factors.Study 1 using the method of video short film to induce different emotions of students with subthreshold depression,and to explore the effects of different emotional states on students with subthreshold depression.study 2: on the basis of study 1,we added the variable of emotion regulation strategy,aimed at guiding subjects to implement emotion regulation strategy through emotion regulation guidance in happy and sad emotional state,and explored the effect of cognitive re-evaluation and expression inhibition on emotion regulation and risk decision of students with subthreshold depression.The results are as follows:(1)Under different emotional states,there were differences between students with subthreshold depression and those with normal subjects.Under the emotional state of sadness,subjects with subthreshold depression experienced more sadness than subjects with normal control group.(2)There are differences in risk decision-making between students with subthreshold depression and normal students in different emotional states: compared with normal individuals,individuals with subthreshold depression tend to avoid risk,especially in sad mood.(3)Subthreshold depressive individuals used cognitive re-evaluation strategy to increase the positive(happy)emotional experience,reduce the negative(sad)emotional experience,the use of expression to suppress emotional changes no difference;normal individuals used cognitive re-evaluation of the emotional regulation effect is better than subthreshold depression individuals.(4)The emotion regulation strategy influenced the risk decision of college students.Subthreshold depressive individuals and normal individuals were more inclined to risk seeking than expression inhibition strategies.(5)Emotional state and emotion regulation strategies affect the risk decision-making of college students together.When using cognitive re-evaluation strategy,college students in happy mood state tend to seek risk more than in sad mood state.
