| Young college students are the future of society,and the mental health condition of college students is highly valued by the state.Although young college students are facing various pressures from academic,employment and interpersonal aspects,their stress responses show individual differences.Stress sensitivity refers to the reactivity of individuals to subtle stressful events in their lives,and is one of the main manifestations of individual differences in stress responses.Based on the existing research,this study combined test,interview and experimental methods to investigate the conceptual connotation,main characteristics and psychological structure of stress sensitivity,to conduct an overall analysis of the stress sensitivity characteristics of contemporary college students,to identify the changing trends and characteristics of emotional changes in individuals with high or low stress sensitivity under stressful conditions,and to reveal the cognitive processing characteristics of individuals with high stress sensitivity.It can further deepen the understanding of stress response process and provide research directions for subsequent interventions in high stress-sensitive individuals.Based on the above research objectives,Study 1 first used semantic analysis to distinguish stress sensitivity from stress susceptibility and to clarify the conceptual connotations of stress sensitivity,and then developed the Stress Sensitivity Scale for University Students and tested its reliability.Study 2 firstly used a test to understand the overall situation of stress sensitivity among contemporary university students,and analysed the relationship between stress sensitivity and academic adaptation and academic stress.An experience sampling method was then used to investigate the characteristics of changes in stress sensitivity during stressful situations and their relationship with negative mood and psychotic symptoms.Study 3 used a 2(word category: high stress words,low stress words)x 2(group: high stress sensitivity group,low stress sensitivity group)experimental design and adopted an emotional stroop paradigm to examine the effects of cognitive characteristics of high and low stress sensitivity college students on stress-related stimuli(high and low stress words).The specific findings of the study are as follows.The results of Study 1 revealed that:Stress sensitivity and stress susceptibility differed significantly on four of the nine dimensions of the Semantic Analysis Scale.The Stress Sensitivity Scale for College Students included eight dimensions,namely loss of control,responsiveness,negative emotions,physical symptoms,negative bias,emotional loss of control,introversion,and decision-making difficulties.The Stress Sensitivity Scale for University Students had good reliability and validity as a measurement tool and can be used in follow-up studies of stress sensitivity.The results of Study 2 revealed that:The overall stress sensitivity among university students was in the range from medium to low and differs by gender,with females having significantly higher stress sensitivity than males,with no significant differences in grade,place of origin,or whether the only child or not;stress sensitivity played a partially mediating role between academic stress and learning adaptation.During stressful periods,students with high stress sensitivity showed significantly higher levels of negative emotions and psychotic symptoms than students with low stress sensitivity;stressful situations caused a slight increase in individual stress sensitivity levels.The results of Study 3 revealed that:The interaction effect of stress sensitivity and lexical type was significant.Highly stress-sensitive individuals had a significant attentional bias towards stress-related negative information,as evidenced by the fact that highly stress-sensitive individuals were more easily distracted by stressful stimuli and took longer to colour name the stimulus material;within the highly stress-sensitive group,subjects took longer to respond to high stress words than to low stress words. |
