The Cigarette Purchase Task is a behavioral economic assessment tool designed to measure the relative reinforcing efficacy of cigarette smoking across different prices. An exponential demand equation has become a standard model for analyzing purchase task data, but its utility is compromised by its inability to accommodate values of zero consumption. We propose a two‐part mixed effects model that keeps the same exponential demand equation for modeling nonzero consumption values, while providing a logistic regression for the binary outcome of zero versus nonzero consumption. Therefore, the proposed model can accommodate zero consumption values and retain the features of the exponential demand equation at the same time. As a byproduct, the logistic regression component of the proposed model provides a new demand index, the “derived breakpoint”, for the price above which a subject is more likely to be abstinent than to be smoking. We apply the proposed model to data collected at baseline from college students (N = 1,217) enrolled in a randomized clinical trial utilizing financial incentives to motivate tobacco cessation. Monte Carlo simulations showed that the proposed model provides better fits than an existing model. We note that the proposed methodology is applicable to other purchase task data, for example, drugs of abuse. 相似文献

Sexual victimization is associated with mental health problems, trauma, substance use, and incarceration. We recruited 200 formerly incarcerated women with substance use disorders in Chicago. We examined whether empowerment moderates relationships between trauma symptoms, trading sex, and being forced to have sex. There was a significant 3-way interaction among sexual coercion, trading, and empowerment scores on trauma symptoms. For women who have not traded sex, lower levels of empowerment were associated with a larger difference in trauma symptoms between women who have been coerced or traded sex. For women who had been coerced, lower levels of empowerment were associated with a larger difference in trauma symptomatology between those who have traded sex or not. Promoting empowerment in sexually traumatized women might reduce the harm that results from being victimized. Furthermore, providing interventions that educate women regarding gender and cultural roles could help women avoid situations that result in exploitation. 相似文献

African‐American adolescents exposed to neighborhood disadvantage are at increased risk for engaging in problem behavior and academic underachievement. It is critical to identify the mechanisms that reduce problem behavior and promote better academic outcomes in this population. Based on social disorganization and socioecological theories, the current prospective study examined pathways from parental monitoring to academic outcomes via externalizing behavior at different levels of neighborhood disadvantage. A moderated mediation model employing maximum likelihood was conducted on 339 African‐American students from 9th to 11th grade (49.3% females) with a mean age of 14.8 years (SD ± 0.35). The results indicated that parental monitoring predicted low externalizing behavior, and low externalizing behavior predicted better academic outcomes after controlling for externalizing behavior in 9th grade, intervention status, and gender. Mediation was supported, as the index of mediation was significant. Conversely, neighborhood disadvantage did not moderate the path from parental monitoring to externalizing behavior. Implications for intervention at both community and individual levels and study limitations are discussed. 相似文献

The objective was to evaluate the validity of sluggish cognitive tempo (SCT) and ADHD-inattention (IN) symptoms in children from Nepal. Teachers rated SCT, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), oppositional defiant disorder (ODD), anxiety, depression, academic impairment, social impairment, and peer rejection dimensions in 366 children (50 % girls) in first through sixth grades (M age?=?9.35, SD age?=?1.96) on two separate occasions separated by 4-weeks. Seven of the eight SCT symptoms and all nine ADHD-IN symptoms showed convergent validity (substantial loadings on their respective factors) and discriminant validity (higher loadings on their respective factor than the alternative factor) at both time-points. Across all three separate analyses (assessment 1, assessment 2, and from assessment 1 to assessment 2), higher SCT scores were associated with lower ADHD-HI scores and higher depression, academic impairment, and social impairment scores after controlling for ADHD-IN while higher ADHD-IN scores were associated with higher ADHD-HI, ODD, academic impairment, and peer rejection scores after controlling for SCT. Also, as hypothesized, SCT scores were not related to ODD scores after controlling for ADHD-IN. The study provides the first evidence for the internal and external validity of the SCT dimension relative to the ADHD-IN dimension with teacher ratings of children from Nepal, thereby increasing the validity of the SCT construct beyond North America, Western Europe, South America, and South Korea. 相似文献

Flow is a psychological state people experience when performing highly challenging tasks with a high degree of skill. It is related to happiness, creativity, and productivity. In three experiments, we developed a manipulation of flow and assessed its effects on subsequent defensive behavior. In all three experiments, participants who played a game with more features of flow (e.g. engagement, match of challenge and skill, performance feedback) reported more feelings of flow (e.g. enjoyment, concentration and interest) and less downstream defensiveness. The results suggest that we developed a flexible, reliable manipulation of flow, and that inducing people to experience flow may reduce their subsequent defensive behavior. 相似文献

This paper is based on current research which is concerned with the revival of religious and ethnic identity among Jews in Hungary after the collapse of communism. Several non-governmental institutions, groups and individuals from various countries, but especially Israel, the UK and the USA, are involved in the revitalization and transformation of Jewish life in the areas of education, ethnicity, religion and social welfare. I examine the complex relationship between emigre donors, often from an Hungarian background, and local Hungarian Jews, to show how cultural aid is accepted, transformed and sometimes resisted. Such aid is not uni-directional from donor to recipient. Rather, it may require the donors to modify their goals; to realize that their assessment of Hungarian needs may be based on anachronistic attitudes. The impact of the recipients on the donors is such that reciprocal change occurs between the two parties. 相似文献

The results reported herein support the hypotheses that (1) situation-specific, contextual features of a task can cause people to use explanation-based reasoning (Pennington and Hastie, 1993); (2) such reasoning can cause experienced personnel, both individually and in two-person teams, to reinterpret the meaning of the same information when it is presented in two different ordered sequences; and (3) the result will be primacy or recency (or no) effects depending on whether the most recent conflicting information can be explained away or not, respectively. These results extend the belief-adjustment model proposed by Hogarth and Einhorn (1992), which does not address information reinterpretations, and always predicts recency effects for an evaluation task with a short series of conflicting information. More generally, the results demonstrate the importance of situation-specific, contextual features in understanding judgment processes. © 1997 John Wiley & Sons, Ltd. 相似文献

The present study investigated the psychological health effects and motivational origins of digital stress based on a representative survey of 1,557 German Internet users between 14 and 85 years of age. Communication load resulting from private e-mails and social media messages as well as Internet multitasking were positively related to perceived stress and had significant indirect effects on burnout, depression, and anxiety. Perceived social pressure and the fear of missing out on information and social interaction were key drivers of communication load and Internet multitasking. Age significantly moderated the health effects of digital stress as well as the motivational drivers of communication load and Internet multitasking. The results, thus, underline the need to address digital stress from a life span perspective. 相似文献
