The Maryland Resource for the Behavioral Utilization of the Reinforcement of Negative Stimuli (MRBURNS) is a novel behavioral task designed to measure individual differences in negative reinforcement-based risk taking propensity. Performance on the MRBURNS has been linked with alcohol-related problems and negative reinforcement-based drinking motives, as well as symptoms of anxiety and depression; however, it is unclear if performance on the task represents a stable measure of negative reinforcement-based risk taking over time. As such, the current study aimed to examine the test–retest reliability of the MRBURNS over a period of one year. Results indicate that the correlation between year 1 and year 2 risk behavior (average number of pumps) on the MRBURNS was .43 across all trials. With the one year test–retest reliability of the MRBURNS established, the MRBURNS may be a useful approach to measuring the relative contribution of negative reinforcement-based risk taking in the development of risky behaviors over time, and may be used to monitor the effects of novel interventions that aim to reduce negative reinforcement based risk taking in the real world. 相似文献

本研究拟探讨5-HTTLPR基因多态性与母亲早期养育压力对中国汉族学前儿童问题行为的交互作用机制和性别差异。355名6个月婴儿及其父母参加了本研究。在婴儿6个月时,收集婴儿的口腔脱落细胞和母亲养育压力数据;在48个月时,再次邀请父母分别报告儿童的问题行为。结果发现:(1)当母亲养育压力较高时,s/s和s/l型男孩的外显问题行为显著高于l/l型男孩;但当母亲养育压力较低时,两组男孩没有显著差异;(2)当母亲养育压力较高时,l/l型女孩的内隐问题行为显著高于s/s和s/l型女孩;但当母亲养育压力较低时,两组女孩没有显著差异。研究结果表明,5-HTTLPR基因多态性与母亲养育压力在预测男孩外显问题行为和女孩内隐问题行为时的交互作用机制均支持素质-压力模型。 相似文献

ABSTRACT A significant number of breast cancer survivors are living with their minor children. In this review we investigated the impact of maternal breast cancer on children. A literature search conducted through PubMed, Scopus, Cochrane Library and CINAHL yielded 26 relevant studies, which documented a variety of effects. Evidence has been presented that dealing with maternal breast cancer can cause uncertainty, anxiety and depression in children, but may also lead to enhanced social and academic performance. The risk of problems in these children is reported to be associated with both low parental affective responsiveness and excessive parental involvement. Internalising child problems were shown to be linked with maternal depression and family dysfunction, and externalising problems with family dysfunction and communication problems. Some of these problems may be modified by interventions for supporting these families, which should be designed to include both parents and children, and also the healthcare personnel. 相似文献
