Study On The Social Function And It's Correlated Factors In Patients With Head Injury

Objective: To investigate the prevalence and the correlated factors of social function in patients with head injury, To compare the incidence of social function disorders and mental disorder in patients with or without brain injury based on CT or MRI; By using social function way, to provide evidence for the severity of head injury, and the evaluation of mental injury as well.Method: To use a series of social function tests to assess the social function of 56 out-patients without brain injury based on CT or MRI in Sichuan university West China Hospital and that of 55 brain injury controls. The social function tests included SDSS, GAF and GAS; 111 subjects with head injury were assessed SCL —90, SDS, SAS and social support tests, at the same time, evaluated with SCID-I/ P and MMSE. Based on the DSM-IV, CCMD-3 and ICD— 10, mental disorders were diagnosed. All statistical analysis has adopted SPSS10.0 software packet that is international used. Statistic description, t-test, chi-square test, rank sum test, Pearson correlation analysis and multiple regressive test were used to analyze the collected data.Results: The study found that the incidence of social function deficit based on SDSS score was 39.6% in 111 patients of headinjury. And the incidence of social function deficit among patients without CT or MRI abnormality was 33.9% ,at the same time, that of the control was 45.5%.The result of statistical analysis manifested that the incidence of social function deficit of two groups was not significant( x 2= 1.544, P = 0.214).The difference of GAS score of two groups wasn't significant t = 0.021, P=0.983),and the difference ofGAF score of two groups as well (t=0.391, P=0.697) .Among patients, there were 97 (87.4%) who had different kinds of mental disorders. Further more, the study displayed that the social function deficit in the patients with head injury were positive correlated with depression and intelligence lesion. At the same time, the social function deficit was not related to CT abnormality( x 2 — 0.598, P = 0.560).Conclusion: The study found that the incidence of social function deficit in the patients with head injury was higher, and implied that the social function of the patients without CT or MRI abnormality was the same impaired as the patients with CT or MRI abnormality. It was necessary to pay attention to this result in the assessment of mental injury. The difference of social function level was not significant in the two groups. The social function deficit was not related to CT abnormality. Therefore, we suggest that the evaluation of mental injury could be partly based on the degree of social function deficit.
