Research on whether parents of children with externalizing disorders are at elevated risk for alcohol problems is equivocal. To reduce this ambiguity, we examined how individual differences in stress reactivity might moderate the drinking behavior of such parents. Parents (119 mothers, 44 fathers) of ADHD sons interacted with different child confederates during each of two counter-balanced sessions. In one, the confederate portrayed a friendly, cooperative, “normal” boy; in the other, the confederate portrayed a “deviant” boy who exhibited behavior characteristic of externalizing disorders. Following each interaction, parents were given an opportunity for ad lib consumption of alcohol while anticipating a second interaction. Latent class analysis identified three subgroups of parents using distress scores and alcohol consumption: minimal stress reactivity; reacts to child deviance with increased distress, but not increased drinking; marked stress-induced drinking. Decisions about the nature and proper treatment of parents raising children with ADHD may be compromised by failure to attend to individual differences in stress reactivity and inclinations to use drinking to cope. 相似文献

Ecological momentary assessments (EMA) of anxiety and anger/hostility were obtained every 25–30 min over two 24-h periods, separated by a median of 6 months, from 165 employees at a university in the Northeast. We used a multilevel trait-state-error structural equation model to estimate: (1) the proportion of variance in EMA anxiety and anger/hostility attributable to stable trait-like individual differences; (2) the correspondence between these trait-like components of EMA anxiety and anger/hostility and traditional questionnaire measures of each construct; and (3) the test–retest correlation between two 24-h averages obtained several months apart. After adjustment for measurement error, more than half the total variance in EMA reports of anxiety and anger/hostility is attributable to stable trait-like individual differences; however, the trait-like component of each construct is only modestly correlated with questionnaire measures of that construct. The 6-month “test–retest” correlations of latent variables representing the true 24-h EMA average anxiety and average anger are quite high (r ? 0.83). This study represents the longest follow-up period over which EMA-based estimates of traits have been examined. The results suggest that although the trait component (individual differences) of EMA momentary ratings of anxiety and anger is larger than the state component, traditional self-report questionnaires of trait anxiety and anger correspond only weakly with EMA-defined traits. 相似文献

Four studies present the first evidence showing that public (vs. private) provocation augments triggered displaced aggression by increasing the perceived intensity of the provocation. This effect is shown to be independent of face‐saving motivation. Following a public or private provocation, Study 1 participants were induced to ruminate or were distracted for 20 min. They then had an opportunity to aggress against another person who either acted in a neutral or mildly annoying fashion (viz. triggering event). As expected, the magnitude of the greater displaced aggression of those who ruminated before the triggering event compared with those distracted was greater under public than private provocation. Study 2 replicated the findings of Study 1 and confirmed that public provocations are experienced as more intense. Studies 3 and 4 both manipulated provocation intensity directly to show that it mediated the moderating effect of public/private provocation found in Study 1. The greater intensity of a public provocation increases reactivity to a subsequent trigger, which in turn, augments triggered displaced aggression. Aggr.

The prevalence and pervasive nature of technology has fundamentally changed how individuals interact. Social networking has significantly altered communication and interaction patterns and created a dynamic venue for perpetration and victimization of bullying. A large population of middle and high school students was surveyed on perceptions and engagement in drug and alcohol usage, school violence, social networking usage, and cyberbullying victimization and perpetration. Findings indicate that although cyberbullying has many similarities to traditional bullying, there are important differences. Participation in school violence and usage of alcohol, tobacco, and illegal drugs predict both victimization and perpetration of cyberbullying. 相似文献

This article reviews, and offers supportive reflections on, the main points of Ernan McMullin's provocative 1998 article, “Cosmic Purpose and the Contingency of Human Evolution,’’ reprinted in this issue of Zygon. In it he addresses the important science‐theology issue of how the Creator's purpose and intention to assure the emergence of human beings is consonant with the radical contingency of the evolutionary process. After discussing cosmic and biological evolution and critically summarizing recent solutions to this question by Keith Ward, John Polkinghorne, Arthur Peacocke, Alvin Plantinga, and others, who presuppose in different ways that God is subject to time, McMullin compellingly argues for the traditional position, that God is unconditioned by time, and this enables God to work purposefully through contingency, randomness, and chance just as easily as through law‐like regularity. 相似文献

Relative to other components of Clark and Wells’ (1995) model, anticipatory processing has been understudied, despite research that suggests that anticipatory processing may maintain social anxiety through mechanisms such as increased anxiety, negative memory biases, and other negative consequences. Anticipatory processing has only been examined as a unitary process, with no efforts examining the underlying structure of this process. The purpose of the current study was to examine the factor structure of the Anticipatory Social Behaviours Questionnaire (ASBQ, Hinrichsen and Clark Journal of Behavior Therapy and Experimental Psychiatry, 34, 205–218, 2003) and identify relationships between the measure’s factors and other constructs of social anxiety. Study 1 (N?=?861) used exploratory factor analysis and concluded that a two-factor model (Avoidance and Preparation) was the best conceptualization of anticipatory processing. Study 2 confirmed the two factor model in a separate sample (N?=?485) and demonstrated the superiority of the two-factor model over a unitary model. Results of Study 3 suggested that, with a sample of high-socially-anxious undergraduates (N?=?59), the Avoidance factor was more maladaptive than the Preparation factor. Results are discussed in the context of the anticipatory processing literature and future directions are proposed. 相似文献

AbstractSalespeople use a variety of selling techniques in their jobs. Little published research, however, has examined how adequately sales training programs prepare sales personnel to employ these techniques. This paper reports the results of a survey that focused on salespeople's adequacy of preparation to utilize various sales techniques. The results of the study lead to several managerial implications about how to improve sales training programs. 相似文献
