Conditioned responses to drug-related environmental cues (such as craving) play a critical role in relapse to drug use. Animal models demonstrate that repeated exposure to drug-associated cues in the absence of drug administration leads to the extinction of conditioned responses, but the few existing clinical trials focused on extinction of conditioned responses to drug-related cues in drug-dependent individuals show equivocal results. The current study examined drug-related cue reactivity and response extinction in a laboratory setting in methamphetamine-dependent individuals. Methamphetamine cue-elicited craving was extinguished during two sessions of repeated (3) within-session exposures to multi-modal (picture, video, and in-vivo) cues, with no evidence of spontaneous recovery between sessions. A trend was noted for a greater attenuation of response in participants with longer (4-7 day) inter-session intervals. These results indicate that extinction of drug cue conditioned responding occurs in methamphetamine-dependent individuals, offering promise for the development of extinction- based treatment strategies. 相似文献

In accordance with the Self‐determination Theory (SDT), six dimensions of parenting (autonomy support vs. psychological control, structure vs. chaos, warmth vs. rejection) could be defined in their relation to adolescents’ adjustment. However, the mechanisms of these relations need to be further deepened. In accordance with SDT, the aims of this study were: (1) to examine the relationships between the six dimensions of parenting and the three psychological basic needs; (2) to examine the mediation role of basic psychological needs in the relation between parental practices, and positive and negative outcomes in a sample of Italian adolescents. In a sample of 342 adolescents, results suggest that supportive parenting practice (autonomy support, structure, and warmth) promotes need fulfillment and adjustment, while thwarting parenting practice (psychological control, chaos, and rejection) reduces need fulfillment and adjustment. Furthermore, the three psychological basic needs (autonomy, competence and relatedness) mediate the relations between parenting and adolescents’ adjustment. These findings highlight the role of parenting in adolescents’ adjustment and in line with SDT provide evidence of the dynamic between parenting, psychological needs and adjustment. 相似文献

Despite extensive research regarding patterns and outcomes of victimization in dating relationships, there has been limited investigation of the developmental profiles of the perpetration of adolescent dating abuse (ADA). We estimated longitudinal latent growth models of ADA perpetration in a sample of 2,269 U.S. adolescents/young adults ages 12–18 at baseline, drawing on four waves (2013–2017) of data from the nationally representative Survey of Teen Relationships and Intimate Violence. Model results revealed three classes representing “nondaters,” respondents showing “increasing dating/ADA,” and respondents with “high/stable dating/ADA.” Results support prior research finding heightened patterns of ADA perpetration by older youth, and distinguish individual and family characteristics associated with adolescent/young adults’ ADA perpetration for the purpose of informing individual and programmatic prevention efforts. 相似文献

Psychopathy is a disorder that occurs primarily in males. Offenders with psychopathic traits are responsible for a disproportionate amount of crime in society, particularly violent crime. Early childhood is a time when individual differences in empathy and guilt—key indicators of the construct of psychopathy—are first evident. A growing number of longitudinal studies have begun to investigate how factors in infancy and early childhood predict psychopathic-like traits in later childhood, adolescence, and adulthood. These studies have suggested that parenting styles during infancy (parental sensitivity, maternal harsh intrusion, commenting on the emotional state of the child) as well as attachment styles are predictive of later psychopathic-like traits. In addition, child characteristics such as temperament and the functioning of biological systems such as the autonomic nervous system and hypothalamic–pituitary–adrenal axis are predictive. Overall, studies have suggested that at least some of the origins of psychopathic traits are present in infancy and early childhood, which is consistent with the perspective of psychopathy as a neurodevelopmental disorder. A recent evolutionary-developmental model provides hypotheses regarding how psychopathy may develop and why it is more common in males than females. This model, and its implications for intervention, is discussed in the context of the longitudinal studies that have been conducted on psychopathy. 相似文献

Toddlerhood is a sensitive period in the development of self-regulation, a set of adaptive skills that are fundamental to mental health and partly shaped by parenting. Healthy sleep is known to be critical for self-regulation; yet, the degree to which child sleep alters interactive child–parent processes remains understudied. This study examines associations between observed parenting and toddler self-regulation, with toddler sleep as a moderator of this association. Toddlers in low-income families (N = 171) and their mothers were videotaped during free play and a self-regulation challenge task; videos were coded for mothers’ behavior and affect (free play) and toddlers’ self-regulation (challenge task). Mothers reported their child's nighttime sleep duration via questionnaire. Results revealed significant Sleep × Maternal Negative Affect and Sleep × Maternal Negative Control interactions. Children who did not experience negative parenting had good self-regulation regardless of their nighttime sleep duration. For children who did experience negative parenting, self-regulation was intact among those who obtained more nighttime sleep, but significantly poorer among children who were getting less nighttime sleep. Thus, among children who were reported to obtain less nighttime sleep, there were more robust associations between negative parenting and poorer self-regulation than among toddlers who were reported to obtain more sleep. 相似文献

This article describes an infant–toddler court team in Michigan, the community-based participatory research approach to the implementation evaluation, and the resulting changes in parenting. Like other court teams, Michigan's Baby Court is led by a science-informed jurist, and all service providers are knowledgeable about the developmental needs of young children and engage in collaborative communication throughout the case. Relationship-based treatment in the form of infant mental health home-visiting was provided to families. Sixteen parents participated in pre- and posttest evaluation visits to assess changes in parents’ reflective functioning and interactions with their child. Findings suggest improvements in parents’ responsiveness, positive affect, and reflective functioning, with moderate effects. Higher risk parents demonstrated significant changes in reflective functioning, as compared to those at lower risk. These findings add to and support the limited literature on the effectiveness of infant–toddler court teams, which include relationship-based and trauma-informed services. 相似文献

采用环境×基因×环境(E×G×E)研究设计, 以637名青少年为被试, 考察了负性生活事件、COMT基因Val158Met多态性和父母教养行为对青少年早期抑郁的影响。结果发现:负性生活事件对青少年早期抑郁具有显著正向预测作用, 且COMT基因Val158Met多态性和父亲积极教养行为在其中起调节作用, 但该调节作用仅存在于男青少年群体中:在携带Val/Val基因型的男青少年中, 当父亲积极教养行为水平较低时, 青少年的抑郁水平随负性生活事件的增多而显著上升, 当父亲积极教养行为水平较高时, 负性生活事件对抑郁无显著预测作用; 在携带Met等位基因的男青少年中, 上述交互作用不显著。 相似文献

研究旨在探讨父亲和母亲的抚养压力在母亲抑郁与学龄前儿童内、外部问题行为间的作用。以北京市某区75所幼儿园的2222名3~5岁在园幼儿及其父母为被试,采用《流调中心抑郁量表》、《抚养压力量表》、《学龄前儿童问题行为问卷》分别对母亲抑郁、父母抚养压力及儿童问题行为进行测查,结果发现:(1)母亲抑郁可以正向预测儿童的内、外部问题行为;(2)母亲抑郁对儿童内部问题行为的作用被"母亲抚养压力"、"母亲抚养压力-父亲抚养压力"两条路径部分中介;(3)母亲抑郁对儿童外部问题行为的作用被"母亲抚养压力"、"母亲抚养压力-父亲抚养压力"两条路径完全中介。综上,研究揭示了母亲抚养压力、父亲抚养压力在母亲抑郁和学龄前儿童内、外部问题行为间的链式中介作用。 相似文献

以105名2岁儿童及其母亲为被试,采用实验室录像观察法,探讨在自由游戏情景下母亲教养目标、使用策略及两者的关系.母亲的教养目标分为四个方面:鼓励儿童的独立、鼓励儿童的接近、不鼓励独立和不鼓励接近;根据压力程度的不同将教养策略分为三大类共11种.结果表明:(1)鼓励儿童独立自主活动是母亲在自由游戏情景下的主要教养目标;(2)母亲使用得最多的为中等程度压力策略、其次是低压力的建议策略;(3)与四种教养目标相关密切的为中、低程度压力的教养策略,即建议、解释、积极评价和指导,在否定的教养目标下使用高压力的干扰和坚持要求执行策略. 相似文献
