The Influence Of Domestic Violence Experience On The Threat Sensitivity Of University Students

The experience of domestic violence includes not only the physical violence and mental violence that adults in the family directly impose on individuals,but also the violence witnessed between family members.The former can be referred to as direct domestic violence while the latter is to witness domestic violence.Both forms of domestic violence experience can affect individuals' cognitive development,emotional development,and behavioral development.Threat sensitivity can be understood from two perspectives: physiological orientation and cognitive orientation.Threat sensitivity of the physiological orientation refers to the sensitivity of the threat defense system,and operational definition as the physiological,emotional,and behavioral response level of the body's response to the threat process.Measured scales include Behavioral Inhibition Scale(BIS)and revised Reinforcement Sensitivity Theory(r-RST).BIS includes behavior activation system and behavior inhibition system.Besides behavioral activation system and behavior inhibition system,r-RST also includes an r-FFFS system that more fully describes the physical,emotional,and behavioral responses to threats.Threat alert is the most used conceptual expression in the field of cognitive orientation threat sensitivity.It refers to the sensitivity characteristics of relatively more cognitive resources invested in threat information during the processing of threat information.It is expressed as a high expectation before threats appeared and high level of threat detection after threats appeared.The operational definition is the interpretation bias and attentional bias toward threat stimuli.There are mature tools for measuring the threat sensitivity abroad,and studies have found that domestic violence experience can affect children's/adults' threat sensitivity.Although there is a behavioral inhibition /activation system scale in China,this scale lacks a behavioral response system in which the individual responds to threats.Therefore,this study intends to revise the more complete the r-RST scale,using Chinese college students as the research object,to investigate the impact of domestic violence experience on threat sensitivity through questionnaire surveys(physiological perspectives)and cognitive experiments(cognitive perspectives).There were two sub studies.Study I(Chapter 3): Study on the characteristics of threat sensitivities of university students experiencing domestic violence,including the revision of the r-RST scale,the comparison of the gender differences of the r-RST scale,and the correlation of the domestic violence experience of college students with the r-RST scale.Research II(Chapter 4 and Chapter 5): Experimental research on the effect of domestic violence experience on the threat sensitivity of college students.This section explores the bias and mechanism of attention to violence threat vocabulary by college students with domestic violence through emotional Stroop paradigm and spatial clue task experiments..The conclusions of this study are as follows:1.The revised r-RST scale included 22 items,which could be divided into three systems:behavioral activation,behavioral inhibition,fight-flight-freezing and five factors: behavioral activation,behavioral inhibition,fight,flight,and freezing.At the same time,the scale had a good internal consistency coefficient,test-retest reliability,and criterion-related validity,and the structural validity fit index is above 0.90,indicating that it had good structural validity,met the measurement requirements,and could be applied to college students;2.Threat sensitivity had significant gender differences in flight factors,freezing factors,and fight-flight-freezing systems.Specifically,female students score significantly higher than boys;domestic violence experience scores and threat-sensitive fight factors,flight factors,and freezing Factors,fight-flight-frzzing systems were all significantly positively correlated.From the physiology perspective,domestic violence experience may affect the sensitivity of college students;3.From the perspective of cognition,domestic violence experience would affect the threat sensitivity of university students.The high family violence experience group had an attention bias toward the threat vocabulary and the nature of attention bias was a difficulty of attention liberation.The low family violence experience group did not have an attention bias to the threat vocabulary.
