A condensed test battery (the CODE) based on the Utrecht Coping List (UCL) and part of the Defense Mechanisms Inventory (DMI) has been developed to assess coping and defense in large population studies. It was tested for reliability and validity in students and back pain patients. Principal components factor analysis of the subscales of the UCL and DMI in the student sample revealed two coping clusters: “Instrumental mastery-oriented coping” and “Emotion-focused coping” and two defensive clusters: “Cognitive defense” and “Defensive hostility”. “Instrumental mastery-oriented coping” was negatively related to subjective health complaints measured with Ursins Health Inventory (UHI). The back pain patients were clearly different from the students, using less coping and more defensive strategies. They had more subjective health complaints that showed negative correlations with “Instrumental mastery-oriented coping”. The CODE is a comprehensive battery that may be valid for large population studies of psychological determinants of muscle pain and other subjective health problems.  相似文献

To investigate whether girls' attributions about computer use were more likely to follow a pattern of learned helplessness, boys' and girls' attributions about a computerized drill-and-practice task and a tutorial program were assessed. Factor analysis of responses on an attribution questionnaire revealed three factors that differed across gender and across task. Multiple regression, using exposure time, group size, attributions, and interactions to predict posttest scores, showed different patterns for boys and girls and between tasks. For the drill-and-practice task, girls benefited from increased exposure time, and attributions to ease of task and ability predicted performance for both boys and girls. For the tutorial task, increased exposure time did not benefit either sex. Girls, however, benefitted from working in larger groups, while boys benefitted from working in smaller groups. Attributions to luck, as well as perceptions of ability and ease of task, predicted posttest scores. However, for girls, attributions to luck predicted higher scores, while for boys, attributions to luck were negatively correlated with performance. Implications for including appropriate feedback to encourage a mastery approach in computer learning, as well as optimal group size and group composition for positive attributional style and academic success, are discussed.This research was supported by Concordia University and the Fonds Pour la Formation des Chercheurs et l'Aide a la Recherche (Grant EQ-2951), Government of Quebec, Canada.The authors wish to thank Ms. Patricia Peters for assistance with the statistical analysis, and Dr. Philip Abrami, for his contribution to the project.  相似文献

There is a recent increase in interest of Bayesian analysis. However, little effort has been made thus far to directly incorporate background knowledge via the prior distribution into the analyses. This process might be especially useful in the context of latent growth mixture modeling when one or more of the latent groups are expected to be relatively small due to what we refer to as limited data. We argue that the use of Bayesian statistics has great advantages in limited data situations, but only if background knowledge can be incorporated into the analysis via prior distributions. We highlight these advantages through a data set including patients with burn injuries and analyze trajectories of posttraumatic stress symptoms using the Bayesian framework following the steps of the WAMBS-checklist. In the included example, we illustrate how to obtain background information using previous literature based on a systematic literature search and by using expert knowledge. Finally, we show how to translate this knowledge into prior distributions and we illustrate the importance of conducting a prior sensitivity analysis. Although our example is from the trauma field, the techniques we illustrate can be applied to any field.  相似文献

The ability to overcome obstacles is widely regarded as a sign of motivation. Building on recent research on nonconscious goal pursuit, two experiments are presented that test whether activating the goal of helping outside people's awareness by exposure to social stereotypes causes them to overcome physical and social obstacles. Experiment 1 established that although overall participants were less inclined to pick up a tissue that was accidentally dropped on the floor by the experimenter when this tissue was dirty instead of clean, they were able to overcome their aversion toward picking up the physical object when they were primed with the mental representation of a social group (e.g., nurse) containing the goal of helping. Results were replicated in Experiment 2, in which participants had to overcome a social obstacle by providing feedback to a student of a negatively evaluated ethnic minority group, and explanations in terms of demand characteristics and mood were excluded. Implications for the literature on nonconscious goal pursuit are briefly discussed. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Episodic memory is the ability to remember personally experienced past events (Tulving in Organization of memory. Academic Press, San Diego, pp. 381–403, 1972). In non-human animals, the behavioural criterion for episodic-like memory is remembering “what” occurred in conjunction with “when” and “where” (Clayton and Dickinson in Nature 395:272–274, 1998). We conducted tests for “what, where, and when” memory in a food-storing bird, the black-capped chickadee (Poecile atricapillus). In Experiment 1, chickadees found sunflower seeds and mealworms in concealed sites in their home cage. Birds later re-visited these sites after either a short (3 h) or long (123 h) retention interval. Chickadees normally prefer mealworms, but at the long retention interval mealworms were degraded in taste and appearance. Chickadees showed some memory for what kind of food they had encountered and where, but no memory for when food had previously been found. Experiment 2 followed a similar procedure, except that chickadees searched for hidden sunflower seeds and mealworms in trees in an indoor aviary. These more natural conditions increased both the spatial scale of the task and the effort required to find food. In this experiment, birds showed evidence for all three components of what–where–when memory. Unlike some previous studies of episodic-like memory, birds’ behaviour cannot be accounted for by differential memory strength for more recent events. The results show that memory for what, where, and when occurs in food-storing birds outside the corvid family, does not require food caching or retrieval, and that remembering “when” can depend on the nature of the task.  相似文献

This study investigated links between three forms of perfectionism and beliefs associated with fear of failure (FF). College students (N = 372) enrolled in physical activity classes completed the Multidimensional Perfectionism Scale and Performance Failure Appraisal Inventory in a single session. After controlling for other forms of perfectionism, only socially prescribed perfectionism (SPP) was strongly associated with beliefs that failure led to aversive interpersonal consequences (i.e., important others losing interest, upsetting important others). Other-oriented perfectionism (OOP) exhibited a weak negative relation with beliefs that failure would lead to devaluation of one’s self-estimate; individuals who held the highest standards for others’ behavior had the weakest beliefs that failure would lead to them devaluing their self-estimate. Self-oriented perfectionism (SOP) was not associated with any beliefs that failure led to aversive consequences; however, when SOP and OOP were simultaneously elevated, they contributed positively to fears of experiencing shame and embarrassment (above and beyond main effects of SPP). Collectively these findings indicated that FF was not ubiquitous with all forms of perfectionism because the specific beliefs about the consequences of failure that underlie different forms of perfectionism varied tremendously. This research was supported in part by a grant from the College of Health & Human Development, The Pennsylvania State University.  相似文献

Gender differences in posttraumatic stress disorder   总被引:3,自引:0,他引:3  
One of the most consistent findings in the epidemiology of posttraumatic stress disorder (PTSD) is the higher risk of this disorder in women. Explanations reviewed within a psychobiological model of PTSD suggest that women's higher PTSD risk may be due to the type of trauma they experience, their younger age at the time of trauma exposure, their stronger perceptions of threat and loss of control, higher levels of peri-traumatic dissociation, insufficient social support resources, and greater use of alcohol to manage trauma-related symptoms like intrusive memories and dissociation, as well as gender-specific acute psychobiological reactions to trauma. This review demonstrates the need for additional research of the gender differences in posttraumatic stress. Recommendations are made for clinical practice.  相似文献

This study tested a person-group dissimilarity model for the relation between peer preference on the one hand, and bullying and victimization on the other. This model accounts for both individual and group (i.e., classroom) factors and postulates that children will be rejected by their peers when they display behaviors that deviate from the group norm. We tested the model in a sample of 2,578 early adolescents in 109 middle school classrooms. Multilevel analysis was used to account for our nested data when examining individual and group effects simultaneously in cross-level interaction terms. The results supported our hypotheses based on the dissimilarity model. Classroom norms of behavior appeared to affect the relation between involvement in bullying and peer preference, in that early adolescents who bullied were more likely to be rejected by their peers in a classroom where bullying was non-normative. In classrooms where bullying was normative, adolescents who bullied were less likely to be rejected or were even liked by their peers (i.e., positive scores on peer preference). The same was true for victimization, although victims still had low scores on peer preference even when victimization was normative. Theoretical and practical implications of these results are discussed in terms of directions for future research and intervention in bullying.  相似文献
