The Attention Bias On Somatoform Disorder And The Relevance With Pain Symptoms

Purpose: To discuss the existence of attention bias and mechanism of the somatoform disorder patients with pain that use the dot detection paradigm and target clues paradigm.To study the relationship between the somatoform disorder with pain and attention to the associated bias.In order to explore the mechanism of somatoform disorders patients with pain.And provide the new theoretical and help for the treatment of the disease.The 90 Symptom Checlist 90(SCL-90)was used to measure the neurotic symptoms of the two groups.Method: Choose the people who were not have conforms to the diagnostic criteria of ICD-10(international classification of diseases-10)of somatoform disorder diagnosis standard as the experimental group of 30 patients with somatoform pain disorder.Selecting 30 normal healthy people cases matched with experimental group of gender,and age,while to exclude the somatoform disorder and other mental diseases and serious illness as control group at the same time.Use the pot detective paradigm and target clues paradigm to measurement and assessment the 30 patients with somatoform disorder(experimental group)and 30 cases of normal subjects(control group).Use overall pain assessment scale--Chinese version(GPS)to measurement and assessment the experimental group.Result:30 cases of experimental group and 30 cases of control group were done the general information questionnaire which design experiment preliminary to collect in advance,and both groups completed the dot detection paradigm and target clues paradigm.There was no significant difference between two groups of gender,age,level of education(P = 0.796,0.588,0.796),the duration of experimental group(2.25±6.95)years.In the dot detection paradigm,the difference of the reaction time of the two properties of images(positive and negative)in control group was not significant(F = 0.119,P = 0.119).There have the significant differences in reaction time of two kinds of properties image(positive and negative)in experimental group.And there have significantly on negative reactions in greater than the positive pictures(F = 21.004,P = 21.004).The reaction time of the negative image of experimental group is longer than the reaction time of the negative image on control group(F = 42.007,P = 42.007).In target clues paradigm,the group under the effective clues and invalid for negative reaction time were longer than positive pictures(F = 17.33,P = 0.00;F = 16.51,P = 0.00),and further simple effect analysis,the experimental group under the condition of invalid clues,the negative images to stimulate on the average reaction time was significantly longer than positive pictures of average reaction time(F = 17.33,P = 17.33).A1B2 in C level effect group under the condition of effective clues,the negative images to stimulate the average reaction time is longer than stimulate the average reaction time of the positive pictures(F = 16.51,P = 16.51).Experimental group overall pain scale score(63.12±19.60),the project is divided into(17.74±6.43)pain,mood project is divided into(16.38±6.50),and clinical manifestations of the project is divided into(16.00±6.35),daily behavior project is divided into(13.00±6.17).Experimental negative images reaction with GPS GPS scale score and emotions,pain symptoms was significantly positively related to project points(r = 0.429,0.416,0.429);Negative images reaction with GPS scale clinical project points and daily behavior projects not related(r = 0.064,0.299);Positive images reaction with GPS scale scores and significantly associated with the fatherless.There have a significantly positive relevance between the reaction of negative picture and the factor scores of SCL90 that includes somatization,obsessive compulsive disorder,terror,phychoticism.There have a significantly negative relevance between the reaction of positive picture and the factor scores of SCL90 that includes somatization and psychotic factors.Conclusion: The somatoform disorders patients with pain have attention bias to negative sentiment,pay attention to the generation mechanism is difficult to remove pay attention.There have the correlated between the pain of somatoform disorder patients of pain and attention bias to negative sentiment.The characteristics of attentional bias and pain were correlated with somatization,obsessive compulsive disorder,terror,phychoticism.
