广泛性焦虑症的直线回归相关与病因推测

Linear regression and etiology inferring of the generalized anxiety disorder

目的:探讨广泛性焦虑症的直线回归相关与病因。方法:广泛性焦虑症SCL-90第三项"头脑中有不必要的想法或字句盘旋"被视为"时点邪念"的大体表现,与同期BAI进行直线回归相关探讨,并结合临床观察思辨其内在关系,进而推测其病因。结果:当BAI采用粗总分计算时,直线回归方程为Y=15.5075+6.8183 X(t=15.36,P<0.01)。当BAI采用标准总分计算时,直线回归方程Y=18.4539+8.1138 X(t=15.36,P<0.01)。同时临床观察到SCL-90第三项"头脑中有不必要的想法或字句盘旋"对同期BAI的消长有先导与决定性的作用,其在整个病程之串联即形成"持久邪念"的主体而决定着广泛性焦虑症的发生与转归。患者的内心能明确体会到SCL-90第三项"头脑中有不必要的想法或字句盘旋"与BAI之间无论是同期或长期都存在因果关系和消长相随的变化关系。结论:二者数学上具有直线关系并呈较强的正相关,临床上观察到具有消长相随的变化关系,能为患者内心明确体会出因果关系和消长相随的变化关系。它们可作为"持久邪念是广泛性焦虑症病因"的三个证据。

Objectives：To investigate the etiology of generalized anxiety disorder by linear regression. Methods：The third item of Self-Report Symptom Inventory （SCL-90）, “Unwanted thoughts, words, or ideas that won’t leave your mind”, is regarded as the appearance of “time-point wicked idea”. To deduct their inner relationship and etiology of generalized anxiety disorder, the linear regression was conducted to analysis the relationship of scores for third item of SCL-90 and Beck Anxiety Inventory （BAI） . Results：When scoring with coarse total score for BAI, linear regression equation is Y=15.5075＋6.8183 X （ t=15.36, P〈0.01）. When scoring with standard total score for BAI, linear regression equation is Y=18.4539＋8.1138 X （ t=15.36, P〈0.01）. Meanwhile, we observed that the“Unwanted thoughts, words, or ideas that won’t leave your mind”has a predictive and decisive effect on scores for BAI. It exists in the whole course of disease as“persistent wicked idea”and plays a decisive role in the onset and outcome of generalized anxiety disorder. The correlative and causal relationships between the third of SCL-90 and BAI are clearly existent in patients’ sense. Conclusion： There is a significant correlation between scores of SCL-90 and BAI in statistics and clinic. This correlation is definitely experienced by patients. These serve as three proofs of the hypothesis that“persistent wicked idea”is the etiology of generalized anxiety disorder.
