冲动性是一种缺乏充分思考、不顾后果的冒险行为或行为倾向, 它既表现在人格特质中, 也会表现为各类环境中的行为。成瘾者具有典型的冲动性特征, 但成瘾者的冲动性是如何影响和促进成瘾行为的发生、发展, 目前还并不明朗。从成瘾形成的不同阶段, 也许可以对此有更进一步的了解。在药物使用的开始阶段, 冲动性人格特质作为动机原因, 促进成瘾物质的首次使用; 接着操作性条件学习导致用药者进入“目标-导向”阶段, 呈现出选择冲动性。第三阶段, 经典条件学习又使相关线索和药物效应不断匹配, 形成条件反射性药物使用行为。成瘾者进入习惯性用药阶段, 表现出显著的停止冲动性。 相似文献

The goal of this study was to determine whether cluster analysis could be used to identify distinct subgroups of text message users based on behavioral economic indices of demand for text messaging. Cluster analysis is an analytic technique that attempts to categorize cases based on similarities across selected variables. Participants completed a questionnaire about mobile phone usage and a hypothetical texting demand task in which they indicated their likelihood of paying an extra charge to continue to send text messages. A hierarchical cluster analysis was conducted on behavioral economic indices, such as demand intensity, demand elasticity, breakpoint, and the maximum expenditure. With the cluster analysis, we identified 3 subgroups of text message users. The groups were characterized by (a) high intensity and low elasticity, (b) high intensity and medium elasticity, and (c) low intensity and high elasticity. In a demonstration of convergent validity, there were statistically significant and conceptually meaningful differences across the subgroups in various measures of mobile phone use and text messaging. Cluster analysis is a useful tool for identifying and profiling distinct, practically meaningful groups based on behavioral indices and could provide a framework for targeting interventions more efficiently. 相似文献

近年来,免疫调节剂(如硫唑嘌呤、6-巯基嘌呤、甲氨喋呤、环孢素等)已广泛应用于临床中,主要用于治疗激素依赖型或激素无效的溃疡性结肠炎患者,显示有良好的疗效。然而,这些药物的剂量、副作用和长期维持治疗,应根据个人的具体情况适当选择适应证,以达到最佳疗效。 相似文献

核苷类似物治疗慢性乙型肝炎中的耐药及治疗决策 总被引:1,自引:0,他引:1
尽管核苷类药物做为慢性乙型肝炎抗病毒治疗的一线用药广泛应用于临床多年,但随着用药时间的延长,治疗过程中出现了耐药这个极具挑战性的问题。核苷类药物的联合治疗或许能阻止或延缓耐药发生。 相似文献

在社会学习理论和生态系统理论基础上提出一个有调节的中介模型,探讨父母心理控制、行为控制与工读生毒品使用的关系,以及结交不良同伴的中介效应和感觉寻求的调节效应。514名工读生完成了父母控制问卷、不良同伴问卷、感觉寻求量表和毒品使用问卷。结果显示:(1)父母心理控制能正向预测工读生的毒品使用,父母行为控制能负向预测工读生的毒品使用。(2)结交不良同伴在心理控制、行为控制与工读生毒品使用的关系中起中介作用。(3)结交不良同伴的中介作用受到感觉寻求的调节。 相似文献

Responses to Life Satisfaction Scale for Problem Youth (LSSPY) items were examined in a sample of 193 substance abusing and conduct disordered adolescents. In responding to the LSSPY, youth endorse their percentage of happiness (0 to 100%) in twelve domains (i.e., friendships, family, school, employment/work, fun activities, appearance, sex life/dating, use of drugs, use of alcohol, money/material possessions, transportation, control of one's life). Results indicated that the LSSPY yielded three factor structures (i.e., Social Satisfaction, External Obligations Satisfaction, Substance Use Satisfaction), demonstrated good initial psychometric properties, and appears to be a useful instrument in the evaluation of treatment outcome in problem youth. Males were more satisfied in the Social and External Obligations domains than females, although no gender differences were indicated in Substance Use Satisfaction. Caucasian, African-American, and Hispanic youths responded to LSSPY items similarly. Future directions are discussed in light of these results. 相似文献

Despite the common occurrence of drug abusers in the psychoanalytic clinic, contemporary literature on the subject, particularly among publications in the IJP, is sparse. This paper aims to review the most important psychoanalytic contributions on drug dependency in the past 100 years, then attempts to compare their postulations to the findings ofpertinent prospective studies. In these patients, a persistent symbiotic object relationship is found, which ties them to narcissistic functioning, where drug use is viewed in the light of both pleasure without object and omnipotently controlled need. The author also discusses the possible contribution of the mother and father in the genesis of this condition, focusing on the compromise of the paternal function as the deciding factor. The theoretical and technical implications of this approach are illustrated by clinical material. 相似文献

Perfectionism and Acceptance 总被引:1,自引:0,他引:1
Lars-Gunnar Lundh 《Journal of Rational-Emotive & Cognitive-Behavior Therapy》2004,22(4):251-265
The present paper argues that there is both a positive and a negative form of perfectionism, and that they can be differentiated in terms of acceptance. The basic argument is that there is nothing unhealthy or dysfunctional about the striving for perfection as such—perfectionism, however, becomes dysfunctional when this striving for perfection turns into a demand for perfection, defined as an inability to accept being less than perfect. Positive perfectionism, in other words, is viewed as a dialectic combination of (a) a striving for perfection, and (b) the acceptance of non-perfection. Some therapeutic implications are discussed, and some directions for further research are pointed out. 相似文献
