摘要:

物质成瘾者具有明显的冲动性特征, 表现为难以戒断的成瘾物质使用。这种行为的产生除了抑制控制的问题外, 源于多个维度的驱动力也是重要的原因。低弱的抑制力无法抵挡驱力的作用, 出现不平衡状态, 形成难以控制的渴求下的强迫性用药或习惯性用药行为倾向。驱动力来源于多方面, 奖赏效应, 通过条件作用形成的S-R式相关线索反应以及感觉寻求等人格特质; 控制成分则包括了反应抑制与无法延迟满足的执行控制功能。

关键词: 成瘾行为, 冲动性, 驱动力, 抑制力

Abstract:

Impulsivity, consisted of driving forces and controlling forces, is an endophenotypic feature which predicts addiction. The driving force is the factor that determines the impulsivity of addiction, while inhibitory control plays the role of regulating the driving force. The addicts of different types all tend to act at a low level of inhibitory control and an abnormally high level of driving force. The imbalance of the two forces can result in drug abuse and relapse.
Reward effect of substance is the main driving force of addiction. Besides, the stimulus-response association triggered by conditional learning, and the personality traits of addicts such as sensation seeking and negative urgency, are all factors associated with driving force. These psychological phenomena can trigger significant impulsivity and evoke habitual and compulsive drug use when inhibitory control is low.
The controlling force mainly includes: the response inhibition characteristic that related to impulsivity personality trait, the cognitive control defect (waiting impulsivity) that cannot delay gratification. Behavioral and neurophysiological studies showed that addicts do possess the traits of low inhibitory control, including at least high sensation seeking and low response inhibition. Rooted in the unusual neurophysiological mechanism, these characteristics may result in the innate susceptibility to drug use and weak inhibitory control among individuals with addition. Waiting impulsivity based on ventral striatum - prefrontal lobe function may also relate to inherited personality traits.
For individuals with addiction, response inhibition and executive control functions that regulate their impulsivity level are influenced by genetic factors and may deteriorate along the course of drug use. The inhibitory and executive control of addicts cannot regulate the tendency of drug use caused by driving forces, thus resulting in impulsive drug use in different stages of addiction.Empirical studies have found that inhibitory control functions remain largely unchanged after short-term abstinence. Moreover, the psychological phenomenon of impulsive personality, which is hereditary, is difficult to be changed within a short time. That is to say, even after a long-term abstinence, it is hardly possible for addicts to elevate the inhibitory control fundamentally. Therefore, one potential way to decrease impulsivity is to alleviate the driving force. Through reducing the reward effect, eliminating the S-R connection or reducing the appearance of related stimulus, the driving force can be decreased, thereby mitigating the impulsivity of drug use. This method might be effective in the treatment of addiction and the prevention of relapse with strong practicability and applicability.
