Study on the physiological factors, psychological factors and social factors of patients with somatoform disorders / 中华行为医学与脑科学杂志

ABSTRACT

Objective To explore the physiological and psychosocial risk factors of the patients with somatoform disorders and to provide references for clinical psychological intervention.Methods Totally 60 patients with somatoform disorder and 60 normal controls were tested with biochemical analyzer,electrocardiogram machine,electroencephalogram machine,computed tomographic scanner,general situation questionnaire,minnesota multiphasic personality inventory(MMPI),toronto alexithymia scale(TAS),life event scale(LES),defense style questionnaire(DSQ) and social support rating scale(SSRS) to explore the physiological and psychosocial risk factors of the patients with somatoform disorders.Results The score of immature defense styles of the study group(4.04±0.89) were higher than those in the control group(3.43 ± 0.65)with significant difference (P＜0.05).The total and factor scores of TAS of study group((86.20±11.15),(21.12±3.28),(26.08±3.86),(18.21±4.69),(23.44±5.60)) were higher than control group((65.00±10.12),(12.43±5.18),(15.64±5.57),(15.56±3.16),(18.71 ±4.30)) with significant difference (P＜0.05).The MMPI scale scores of Hs (hypochondriasis),D (depression),Hy (hysteria),Men-Nancy (Mf),Paranoid (Pa),Psychotic (Pt) were higher in patients with somatoform disorder ((72.79± 10.50),(68.46±13.63),(79.03±12.12),(51.72±7.74),(57.98±10.60),(54.98±8.83)) than those in normal controls((51.66±10.11),(47.96±9.42),(51.47±11.90),(43.66±8.77),(47.67±6.69),(47.48±8.67)) with significant difference(P＜0.05).The total life event score and the negative life event score of LES of the study group ((89.66±68.60),(82.65±65.16)) were higher than those in the control group((56.00±56.79),(39.14± 46.05)) with significant difference (P＜ 0.05).Multiple factors logistic regression analysis showed immature defense styles,higher alexithymia score,higher negative life event score,higher HS,D,Hy of MMPI may increase the risk of somatoform disorders(OR=6.84,9.12,5.83,2.69,1.81,11.20,P＜0.01).Conclusion Patients with somatoform disorder are almost in normal physiological condition.They have the personality characteristics and significant alexithymia.Their social support are almost normal,but they have more negative life events and their defense styles are almost immature.
