Recent literature has focused on the relation between childhood teasing and adulthood psychopathology, with the majority of this work dependent on a single measure, the Teasing Questionnaire-Revised (TQ-R; Storch et al. Journal of Anxiety Disorders 18:681–694, 2004). However, the factor structure and reliability of the TQ-R requires further examination. The present investigation reevaluated the factor structure of the TQ-R in two large samples. In Study 1, three previous factor models were investigated through confirmatory factor analyses (CFAs) in a large clinical sample. Due to their poor fit, exploratory factor analyses (EFAs) were used to investigate alternative factor models. In Study 2, the factor structure of the previous models and new models from Study 1 EFAs were investigated through CFAs and estimates of internal consistency in a large college sample. Together, these findings provided the most support for a new 21-item five factor model, identified in the Study 1 EFAs and supported by the Study 2 CFAs, with the content of the teasing subscales consistent with the constructs of anxiety, appearance, academics, weight, and height. 相似文献

Standard interventions, such as antidepressive medication or psychotherapy, show only medium effect sizes in the reduction of depressive symptomatology. In addition, medication has problematic and not well accepted side-effects therefore it seems reasonable to look for alternative, cost-effective, easily available treatments which show no side-effects. A large number of studies have demonstrated similar neurophysiological effects of sport as antidepressants or psychotherapies but the crucial question remains unanswered: does sport show antidepressive effects by alleviating depressive symptomatology? Some randomized, controlled studies and all available recent meta-analysis addressing this question are reviewed. This review concludes that randomized control trials including sport activities have similar positive effect sizes as psychotherapy or antidepressant studies. The pre-post effects are in the medium to high range. Such a conclusion is jeopardized by a limited number of methodolically sound studies. It is too early to make evidence-based recommendations about the antidepressive effect of sport. Currently, it can only be speculated about moderators and mechanisms mediating outcome. 相似文献

Non‐standard work schedules involve work outside the Monday–Friday daytime hours. Although research has heavily studied the health and family effects of such schedules, few studies have investigated their relationship to retention. We draw from Maertz and Campion's discussion of motivational forces that influence turnover to propose that employees on non‐standard schedules are more likely to quit their employer because of general job dissatisfaction and because of normative pressures from family and/or friends. Specifically, we hypothesized that employees on day shifts or weekday only schedules would remain with their employer longer than those who work on nonday shifts or on the weekends. We also hypothesized that perceived employment mobility would moderate the effects of non‐standard schedules on retention length. Hypotheses were tested among 3,178 retail employees who worked five different distinct shift arrangements and different weekday/weekend schedules. Cox regression analyses indicated that, as hypothesized, employees working nonday shifts or schedules including weekends remained with their employer for a shorter duration of time than employees not on such schedules. Perceived mobility moderated the schedule–turnover relationship, though not in the hypothesized manner. We discuss the theoretical and practical implications of these findings for work schedule assignment and retention strategies. 相似文献

An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling. 相似文献

In the present study, introductory-level German students read a simplified story and learned the meanings of new German words
by reading English translations in marginal glosses versus trying to infer (i.e., guess) their translations. Students who
inferred translations were given feedback in English or in German, or no feedback at all. Although immediate retention of
new vocabulary was better for students who used marginal glosses, students who inferred word meanings and then received English
feedback forgot fewer translations over time. Plausible but inaccurate inferences (i.e., those that made sense in the context)
were more likely to be corrected by students who received English feedback as compared with German feedback, providing support
for the beneficial effects of mediating information. Implausible inaccurate inferences, however, were more likely to be corrected
on the delayed vocabulary test by students who received German feedback as compared with English feedback, possibly because
of the additional contextual support provided by German feedback. 相似文献

Naming a picture is slower while ignoring a semantically related versus an unrelated distractor word (semantic picture–word
interference, or PWI). To locate the PWI effect in the word production processing stream (during perceptual encoding, response
selection, or afterward), we used the psychological refractory period paradigm, in which participants identified a tone and
then, at varying SOAs, named a picture while ignoring a semantically related or unrelated word (following Dell’Acqua, Job,
Peressotti, & Pascali, 2007). As in results from the Stroop paradigm (Fagot & Pashler, 1992), we found equivalent PWI effects at short and long SOAs following tone identification in two experiments, indicating that
semantic competition occurs at response selection or later. Our results suggest that it is premature to assume that competitive
selection occurs at multiple levels in the word production system (van Maanen, van Rijn, & Borst, 2009) or that the Stroop and semantic PWI effects are fundamentally different (Dell’Acqua et al., 2007). 相似文献

Emotion processing and decision-making are integral aspects of daily life. However, our understanding of the interaction between these constructs is limited. In this review, we summarize theoretical approaches that link emotion and decision-making, and focus on research with anxious or depressed individuals to show how emotions can interfere with decision-making. We integrate the emotional framework based on valence and arousal with a Bayesian approach to decision-making in terms of probability and value processing. We discuss how studies of individuals with emotional dysfunctions provide evidence that alterations of decision-making can be viewed in terms of altered probability and value computation. We argue that the probabilistic representation of belief states in the context of partially observable Markov decision processes provides a useful approach to examine alterations in probability and value representation in individuals with anxiety and depression, and outline the broader implications of this approach. 相似文献

The papers in this Special Issue compellingly show that older adults' everyday cognitive life is governed not by the decline in elementary cognitive processes as measured in the lab, but by a multitude of compensatory mechanisms, most of which are of the social/motivational variety. Much of this compensatory behavior can be elicited with no or only little experimental prodding, underscoring the self-organizing or self-initiated nature of this type of behavior, even in advanced old age. We suggest that the study of compensation and the orchestration of cognitive, social, and motivational compensatory mechanisms in effective and healthy aging provides a meaningful challenge to traditional ways of examining developmental changes in cognitive performance. 相似文献
