In this cross-cultural study, the authors attempted to identify high-risk subgroups for alcohol consumption among college students. American and Greek students (N = 132) answered questions about alcohol consumption, religious beliefs, attitudes toward drinking, advertisement influences, parental monitoring, and drinking consequences. Heavy drinkers in the American group were younger and less religious than were infrequent drinkers. In the Greek group, heavy drinkers tended to deny the negative results of drinking alcohol and use a permissive attitude to justify it, whereas infrequent drinkers were more likely to be monitored by their parents. These results suggest that parental monitoring and an emphasis on informing students about the negative effects of alcohol on their health and social and academic lives may be effective methods of reducing alcohol consumption. Classification tree analysis revealed that student attitudes toward drinking were important in the classification of American and Greek drinkers, indicating that this is a powerful predictor of alcohol consumption regardless of ethnic background.  相似文献

This article reports a prospective study of religiousness and recovery from heart surgery. Religiousness and other psychosocial factors were assessed in 142 patients about a week prior to surgery. Those with stronger religious beliefs subsequently had fewer complications and shorter hospital stays, the former effect mediating the latter. Attendance at religious services was unrelated to complications but predicted longer hospitalizations. Prayer was not related to recovery. Depressive symptoms were associated with longer hospital stays. Dispositional optimism, trait hostility, and social support were unrelated to outcomes. Effects of religious beliefs and attendance were stronger among women than men and were independent of biomedical and other psychosocial predictors. These findings encourage further examination of differential health effects of the various elements of religiousness.  相似文献

Experimental work on modes of problem representation (Sylvan, Diascro, & Haddad, 1996) has found that the story model of Pennington and Hastie (1986, 1988) is a helpful construct in understanding how people reach decisions when dealing with questions of foreign policy. Here, a modified version of the story model is applied to statements by military officers in the Soviet Union and in France, representing the situations they face before and after the loss of Eastern Europe and Indochina, respectively (Charlick-Paley, 1997). Both baseline stories and those after the losses of empire are examined to test the hypothesis that when a military experiences the loss of its state's empire, officers will formulate a new story that justifies the change in its status, and that this new story will motivate new patterns of civil-military relations in the post-imperial era. The hypothesis finds general support, and stories are found to be a useful vehicle in understanding differences between groups of military officers. An analysis of how officers' stories change over time yields intriguing results as to how mutable stories are and which elements of a story are most likely to change first. In particular, expansion of the level of a goal is found to be a representational response to the political stimulus of loss of empire.  相似文献

Background

To examine the efficacy of sequential sertraline and cognitive-behavioral therapy (CBT) treatment relative to CBT with pill placebo over 18 weeks in children and adolescents with obsessive–compulsive disorder (OCD).

Methods

Forty-seven children and adolescents with OCD (Range = 7–17 years) were randomized to 18-weeks of treatment in one of three arms: 1) sertraline at standard dosing + CBT (RegSert + CBT); 2) sertraline titrated slowly but achieving at least 8 weeks on the maximally tolerated daily dose + CBT (SloSert + CBT); or 3) pill placebo + CBT (PBO + CBT). Assessments were conducted at screening, baseline, weeks 1–9, 13, and 17, and post-treatment. Raters and clinicians were blinded to sertraline (but not CBT) randomization status. Primary outcomes included the Children's Yale-Brown Obsessive–Compulsive Scale, and response and remission status. Secondary outcomes included the Child Obsessive Compulsive Impact Scale–Parent/Child, Children's Depression Rating Scale-Revised, Multidimensional Anxiety Scale for Children, and Clinical-Global Impressions-Severity.

Results

All groups exhibited large within-group effects across outcomes. There was no group by time interaction across all outcomes suggesting that group changes over time were comparable.

Conclusions

Among youth with OCD, there was no evidence that sequentially provided sertraline with CBT differed from those receiving placebo with CBT.

ABSTRACT

Drawing on survey data from a sample of Latino college students, we examine the generalizability of social learning theory, general strain theory, social bond theory, and self-control theory to a Latino population and consider how these four theories can elaborate on the relationship between immigrant status and substance use. We find that social learning and general strain provide the most robust explanations of substance use across four outcomes. Also, third-plus generation respondents generally reported more substance use than first-generation respondents. Our findings suggest that this latter trend is due mostly to varying effect sizes in social learning by immigrant status.  相似文献

We evaluated the influence of speed–accuracy trade-offs on performance in the sustained attention to response task (SART), a task often used to evaluate the effectiveness of techniques designed to improve sustained attention. In the present study, we experimentally manipulated response delay in a variation of the SART and found that commission errors, which are commonly used as an index of lapses in sustained attention, were a systematic function of manipulated differences in response delay. Delaying responses to roughly 800 ms after stimulus onset reduced commission errors substantially. We suggest the possibility that any technique that affects response speed will indirectly alter error rates independently of improvements in sustained attention. Investigators therefore need to carefully explore, report, and correct for changes in response speed that accompany improvements in performance or, alternatively, to employ tasks that control for response speed.  相似文献

Abstract

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric condition with a heterogeneous array of obsessions and compulsions. Although factor analytic studies have identified symptom dimensions comprising the clinical presentation of OCD, many frequently reported miscellaneous symptoms are not considered in factor analytic studies because they do not fit conceptually within a particular symptom category, despite being functionally related. In the present study, we examined the associations between miscellaneous symptoms and OCD symptom dimensions in a sample of 111 adults with OCD. Overall, most miscellaneous symptoms were associated with one or more symptom dimensions in previously identified four- (14 of the 22 symptoms) and five-factor models (12 of the 22 symptoms). In both models, Contamination/Cleaning was the only dimension not related to any miscellaneous symptom. The present results provide information about which miscellaneous symptoms may be related to particular symptom dimensions, which will assist in clinical evaluations and help planning behavioral psychotherapy (e.g., hierarchy development).  相似文献

Listeners rapidly adjust to talkers’ pronunciations, accommodating those pronunciations into the relevant phonemic category to improve subsequent perception. Previous work has suggested that such learning is restricted to pronunciations that are representative of how the speaker talks (Kraljic, Samuel, & Brennan, 2008). If an ambiguous pronunciation, for example, can be attributed to an external source (such as a pen in the speaker’s mouth), or if it is preceded by normal pronunciations of the same sound, learning is blocked.In three experiments, we explore this blocking effect in more detail. Our aim is to better understand the nature of the representations underlying the perceptual learning process. Experiment 1 replicates the blocking effect. Experiments 2 and 3 demonstrate that it can be eliminated when certain visual information occurs simultaneously with the auditory signal. The pattern of learning and non-learning is best accounted for by the view that speech perception is mediated by episodic representations that include potentially relevant visual information.  相似文献

In the context of decreased demand for whole blood and increased demand for plasma‐derived products, donors in Australia are increasingly being asked to convert from whole‐blood to plasmapheresis donations. Plasmapheresis is a different type of donation to whole blood as the process takes longer and can be engaged in more frequently. What is unknown is whether whole‐blood donors view donating plasma as consistent with their donor identity and how they respond to the possibility of donating more frequently. To explore this, we undertook semistructured telephone interviews with 26 whole‐blood donors who had recently made their first plasma donation. Findings indicated that whereas donating plasma was viewed as a bigger ask than donating whole blood, the former was viewed as consistent with their identity as a donor because both behaviours were seen to benefit others and self and were located within the same institutional context. Donating plasma was an opportunity for donors to enhance their self‐concept as an altruistic giver. When contemplating their future donation behaviour, donors considered how their donor identity would fit alongside other salient roles. These findings have implications for how institutions can position their request of existing donors to give a different gift.  相似文献
