【摘要】： 研究背景:自杀(suicide)是现代社会人类的10大死因之一,并已经成为15-35岁间的年轻人前3位的死因。关于自杀的原因有很多种,但冲动性是一个不可忽视的因素。目前关于冲动的研究样本很多只是局限在自杀未遂和正常人群中,用自杀死亡群体做关于冲动的研究很少,但是用自杀死亡群体做关于冲动的研究最具有说服力。自杀死亡的研究需要心理解剖,而心理解剖方法则需要他评版的心理测量工具。研究目的:本研究旨在修订Dickman冲动量表( Dickman’s Impulsivity Inventory,DII)他评版,在中国东北农村社会文化背景下,通过对DII他评版信度、效度的检验,对在农村自杀死亡的危险因素进行初步验证性研究。到目前为止此类量表还未见他评版本,所以此次修订为探索性的研究。研究方法:随机抽取大连地区庄河农村居民及整群抽取庄河农村2006年6月1日-2008年6月30日自杀死亡病例作为研究对象,进行量表的修订及检验。量表修订程序为(1)在DII正式测验版的基础上对措辞进行修改调整,形成DII他评预测版;(2)将DII他评预测版应用于预实验组的102例农村居民,测验的结果经项目分析后筛选出不合适的题目,对其进行翻译的调整,形成DII他评正式测验版;(3)将DII他评正式测验版施测于参与正式测验的258例农村居民,测验结果经项目分析和因子分析后删除不合适的题目,形成DII他评版;(4)随机抽取参加正式施测的258例农村居民中的52例,于4周后进行重测,以检验量表的重测信度;(5)对DII他评版进行内部一致性信度检验。(6)通过对自杀死亡病例及对照组施测,进行初步验证性研究,检验DII他评版的区分效度。研究结果:(1)预实验的结果显示D5、D7、D18、D20的临界比小于3,并且相关系数得分低于0.3,经过修改调整后,在正式测验的项目分析后删除了鉴别度仍较低的D18;并且将因子分析中两个结果与所测验的目的相反的项目进行交换。(2)DII他评版的信度结果显示本量表具有良好的内部一致性和稳定性,其中,总量表和非功能性与功能性冲动分量表的Cronbach’sα系数分别为0.8795,0.8626,0.8387,分半信度分别为0.8852,0.8352,0.8320,重测信度为0.870;(3)效度分析,结构效度是通过因子分析进行检验,结果支持DII他评版的非功能性与功能性冲动的理论建构;区分效度是对农村自杀人群和与之配对的农村正常人群进行相关分析,结果表明自杀组显著高于对照组,说明DII他评版有区分不同属性人群的能力,具有较好的区分效度。研究结论:DII他评版具有较好的信度和效度,符合心理测量学的要求。DII他评版可用于对农村自杀死亡危险因素的分析,也可用于农村的冲动性人格研究。
[Abstract]:Background: suicide is one of the 10 leading causes of death in modern society and has become the top three causes of death among young people aged 15-35. There are many reasons for suicide, but impulsiveness is a factor that cannot be ignored. At present, a lot of research samples about impulse are confined to attempted suicide and normal population. There are few studies on impulse in suicide death group, but it is most persuasive to use suicide death group to do impulse research. The research of suicide death requires psychological anatomy, and psychological anatomy method requires his psychological measurement tool. Objective: the purpose of this study was to revise the Dickman impulse scale (Dickman's Impulsivity inventor DII), and to test the reliability and validity of DII evaluation under the social and cultural background of rural areas in Northeast China. The risk factors of suicide death in rural areas were preliminarily verified. So far, he has not seen a version of the scale, so this revision is an exploratory study. Methods: random sampling of Zhuanghe rural residents in Dalian area and cluster sampling of Zhuanghe rural areas from June 1, 2006 to June 30, 2008, as research objects, the scale was revised and tested. The revised procedure of the scale was: (1) on the basis of the formal test version of DII, the wording was revised and adjusted to form the DII other assessment prediction version, which was applied to 102 rural residents in the pre-experimental group. After item analysis, the results of the test were selected out and the unsuitable questions were selected, and the translation was adjusted to form the DII he evaluation formal test version. (3) the DII other evaluation formal test version was applied to 258 rural residents who participated in the formal test. After item analysis and factor analysis, the results of the test were used to remove the inappropriate questions and form a DII other evaluation page. 52 of 258 rural residents who took part in the formal survey were randomly selected and re-tested 4 weeks later. To test the reliability of internal consistency of DII's other evaluation version by using the test-retest reliability of test scale / 5) to test the distinguishing validity of DII's other evaluation edition by means of a preliminary confirmatory study on the suicide death cases and the control group. The critical ratio of D _ 5 / D _ 7 / D _ (18) D _ (20) is less than 3, and the score of correlation coefficient is lower than 0.3. After the item analysis of the formal test, D18, which is still low, was deleted; and the reliability of the scale was shown to be good by exchanging two items in factor analysis that were opposite to the purpose of the test. Ministry consistency and stability, Among them, the Cronbach's 伪 coefficients of total table and non-functional and functional impulse component tables were 0.879 5 / 0.8626 / 0.8387, the split-half reliability were 0.8852 / 2 / 0.8352 / 0.8320, and the test-retest reliability were 0.870 / 3, respectively. The structural validity was tested by factor analysis. Results the results supported the theoretical construction of non-functional and functional impulses in DII's evaluation version. The distinguishing validity was to analyze the correlation between rural suicide population and matched rural normal population. The results showed that the suicide group was significantly higher than the control group. It shows that DII has the ability to distinguish different attribute groups, and has good distinguishing validity. Conclusion: DII / DII has good reliability and validity. It can be used to analyze the risk factors of suicide death in rural areas and to study impulsive personality in rural areas.
