Development Of Multidimensional Scale Of Psychosomatic Stress Table(MSPS)

Objective:Based on the former research of SSMD, development MSPS, which hasthe function of screening function of the original by SSMD, and the classification ofthe disease diagnosis function.Method:Adjust the SSMD survey questionnaire in supplement20entries, a total of51, an additional10cardiac adverse events.Using MSPS questionnaire in thecommunity group test and Selected690cases of normal people.In psychosomaticDepartment selected2171cases of patients of all disease.Statistical analysis includeditem analysis,Screening validity study,ROC curve segmentation value, reliability andvalidity testing, research on clustering and validity of disease.Results:(1)Factor analysis indicated that MSPS has23independent factors,accounting for71.238%of the total variance;(2)All MSPS entries identification indexis positive (scoring direction).There was statistical significance in most discriminationindex,2items of no statistical significance.But there is still discrimination in diseaseentry analysis,and after eliminate not significantly increased screening validity,so allthe reservations;(3)The normal group MSPS total score and all the patients thedelimitation of the value of14points,then the positive rate is33.3%in communitypopulation,and diagnosis of leakage for20.1%patients,Missed patient score is lowbecause the K-induced.Instead of the other family members to do the MSPS,the totalscore becomes35.36±21.187of others assessment form19.45±14.329of Selfassessment.(4)Excluding normal samples of patients,and the area under the ROCcurve was0.93;When MSPS total score is13.5,0.826is the largest which is equal tosensitivity+specificity-1.(5)Internal reliability of MSPS:Symptom scale is 0.934,Event scale is0.792.(6)Put forward a new concept and method of a lot ofpsychological measurement technology:Preparation technology of entries;The controlof the subjects’ compliance and the adjustment technique in K score;A small sampleof normal group instead of a large sample of the norm group; Normal samplepurification technology;10-axis medical record format；Clinical normal valuesinstead of psychological norm;ROC segmentation algorithm;Analysis of a largesample of all disease symptom factor;Disease cluster analysis;Validity study insteadof the validity test;Screening validity is not equal to the diagnosticvalidity;Mathematical gold standard of screening study and diagnosis study.Conclusion:MSPS and its predecessor SSMD screening validity are beyond theGHQ12;Screening and diagnostic validity of MSPS transcend the most famousSCL-90and MMPI,and it can do maths classification of diseases.Combination ofMSPS and10-axis medical record in Department of Psychosomatic Medicine canachieve the best diagnostic level.
