The Study On The Relationship Of Impulsiveness With Suicidal Ideation

Suicide is a public health problem, which may have a series of negative effects on the individual,the family and even the whole society. Suicidal ideation is a major psychological activity of the suicide, as well as an important independent predictor of the suicide. In addition, persons at the risk of suicide are more likely to attempt to suicide. Therefore, it is important to understand risk factors impacting the suicidal ideation and suicide risk in order to prevent the suicide. Some studies have shown that there lies a close relationship between some certain personalities and suicidal ideation. However, there are few researches on the relationship of impulsivity with suicidal ideation. Besides, foreign researches on the relationship of impulsivity with suicidal ideation focus on the youngest, and in China, there is only one research on the relationship of impulsivity with suicidal ideation through correlation analysis which takes the suicide attempters as the object.The thesis aims to explore whether there is a relationship between impulsive personality and the emergence and degree of suicidal ideation and suicide risk, in order to propose academic and empirical suggestion for the prevention of the suicide.Total of 1190 rural residents in Laiwu, Shandong province and urban residents in Tianjin were selected by the random number table. Subjects were assessed through 4 questionnaires, including general circumstances,lifetime Suicidal Ideation Scale,Barratt Impulsiveness Scale-11 and Scale for Suicide Ideation through the one-to-one interview. Lifetime Suicidal Ideation Scale is used to assess whether the object has the suicide ideation, Scale for Suicide Ideation is used to evaluate the intensity of the suicide ideation and the suicide risk, Barratt Impulsiveness Scale-11 is used for assessing the impulsiveness. Spearman rank correlation analysis was employed to identify the correlation of impulsivity to the suicidal ideation; t-test analysis was used to distinguish the difference of the impulsivity of persons with suicidal ideation and without suicidal ideation; logistic regression analysis was employed to determine the impact of impulsivity on the suicidal ideation in the context of demographic factors; multiple linear regression analysis was used to determine whether the impulsivity is the independent risk factor of the degree of suicidal ideation and suicide risk in the context of demographic factors. The results got from these methods are as follows:1) Rate of lifetime suicidal ideation of residents is 7.3%.2) Impulsivity may make independent contribution to the appearance and intensity of the suicidal ideation. The stronger the impulsivity, the more likely the appearance of the suicidal ideation and the stronger the suicidal ideation.3) Impulsivity may make independent contribution to the suicide risk. The stronger the impulsivity, the higher the suicide risk.4) There are many demographic factors relating to the suicide ideation, such as: gentle,age,family economic situation and suicide history of familiar persons. The female is more prone to appear suicidal ideation than the male. As growing older, the possibility of the appearance of the suicidal ideation decreases and the suicidal ideation becomes weaker. Persons whose familiar persons had suicide history are more likely to appear suicidal ideation. The better the family economic situation, the stronger the suicidal ideation.5) Gentle has impact on the suicide risk. The male has positive impact on the suicide risk, while the female has negative impact on it. In other words, the male's suicide risk is higher than the female, female is more likely to have suicidal action.This research shows impulsivity is the independent impacting factor on the suicide ideation and suicide risk. Besides, youngsters and the female are at high risk of the suicide ideation and suicide risk. Hence, the society should pay more attention to them to help them keep psychological health and deal with crisis properly.
