概括
药物使用障碍 (SUD) 涉及线索,渴望和使用之间的复杂相互作用. 动态系统理论揭示了两个患者概况:一个是由提示和驱动的,另一个是由使用和驱动的,渴望作为关键调节器.
科学领域:
- 行为科学 行为科学
- 计算精神病学是一种计算精神病学.
- 成研究 研究成研究
背景情况:
- 药物使用障碍 (SUD) 通常被视为从环境线索到渴望和随后的物质使用的途径.
- 了解暗示暴露,渴望强度和实际使用之间的复杂,非线性动态对于有效的SUD治疗至关重要.
- 生态瞬间评估 (EMA) 为分析日常生活中的这些复杂关系提供了有价值的实时数据.
研究的目的:
- 通过使用动态系统理论 (DST) 来研究SUD个体中与物质相关的线索和渴望之间的非线性关系.
- 根据线索对渴望的影响和相反,根据SUD患者的表型,使用季节性自动回归集成移动平均线与异源变量 (SARIMAX) 模型.
- 使用DST来建模SUD的时间动态,探索暗示暴露和渴望强度如何相互作用来预测物质使用.
主要方法:
- 应用DST到EMA的数据来自211个SUD (酒精,烟草,大麻,阿片类药物,可卡因) 的个人.
- 采用优化的线性SARIMAX模型来表型患者数据,识别了154名受渴望暗示影响的患者和57名受渴望暗示影响的患者.
- 开发并调整了两个DST计算模型,以模拟和分析基于SARIMAX发现的线索,渴望和使用之间的非线性相互作用.
主要成果:
- 第一个DST模型,反映了暗示对渴望的影响,确定了一个"最大暗示和"配置文件,其中增加的暗示导致渴望增加,随后减少两者,在渴望之后使用.
- 第二个DST模型,反映了渴望对线索的影响,确定了一个"最大使用和"配置文件,其中增加的渴望导致了更多的线索报告和使用,随后是渴望下降.
- 两种模型都始终表明,渴望行为作为一个关键的中间体之间的提示暴露和物质使用行为.
结论:
- 在SUD患者中,渴望是从线索到物质使用的途径中的中心调节器.
- 已识别的DST模型和患者资料 ("最大提示和"和"最大使用和") 为SUD复杂的时间动态提供了新的见解.
- 这些发现为开发针对物质使用障碍的有针对性的治疗干预措施开辟了新的途径.

Drug Abuse and Addiction: Pharmacological Phenomena
1.1K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Substance Use Disorders Affecting Sleep
398
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Drug Dependence
1.6K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Modeling in Therapy
378
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
