Premenstrual dysphoric disorder is a psychiatric disorder that reportedly affects between 3 to 8% of women. Although not an official diagnosis in the current Diagnostic and Statistical Manual of Mental Disorders, premenstrual dysphoric disorder has received increasing attention in the clinical literature, and considerable debate exists regarding the validity of this proposed condition. This study examined the prevalence of premenstrual dysphoric disorder in a sample of women and men and assessed the construct validity of the disorder. Twenty percent of women met the criteria for provisional diagnosis of premenstrual dysphoric disorder using Diagnostic and Statistical Manual criteria. In addition, 4% of men met these criteria when given sex-neutral assessment forms. Self-reported psychological distress and impaired interpersonal functioning did not predict women's likelihood of meeting the criteria for premenstrual dysphoric disorder. Results cast doubt on the sex-specificity of the diagnostic criteria of premenstrual dysphoric disorder and the construct validity of the disorder. Limitations of this study are discussed. 相似文献

Mechanical Turk (MTurk), an online labor system run by Amazon.com, provides quick, easy, and inexpensive access to online research participants. As use of MTurk has grown, so have questions from behavioral researchers about its participants, reliability, and low compensation. In this article, we review recent research about MTurk and compare MTurk participants with community and student samples on a set of personality dimensions and classic decision‐making biases. Across two studies, we find many similarities between MTurk participants and traditional samples, but we also find important differences. For instance, MTurk participants are less likely to pay attention to experimental materials, reducing statistical power. They are more likely to use the Internet to find answers, even with no incentive for correct responses. MTurk participants have attitudes about money that are different from a community sample's attitudes but similar to students' attitudes. Finally, MTurk participants are less extraverted and have lower self‐esteem than other participants, presenting challenges for some research domains. Despite these differences, MTurk participants produce reliable results consistent with standard decision‐making biases: they are present biased, risk‐averse for gains, risk‐seeking for losses, show delay/expedite asymmetries, and show the certainty effect—with almost no significant differences in effect sizes from other samples. We conclude that MTurk offers a highly valuable opportunity for data collection and recommend that researchers using MTurk (1) include screening questions that gauge attention and language comprehension; (2) avoid questions with factual answers; and (3) consider how individual differences in financial and social domains may influence results.

Studies on adults have revealed a disadvantageous effect of negative emotional stimuli on executive functions (EF), and it is suggested that this effect is amplified in children. The present study’s aim was to assess how emotional facial expressions affected working memory in 9- to 12-year-olds, using a working memory task with emotional facial expressions as stimuli. Additionally, we explored how degree of internalizing and externalizing symptoms in typically developing children was related to performance on the same task. Before employing the working memory task with emotional facial expressions as stimuli, an independent sample of 9- to 12-year-olds was asked to recognize the facial expressions intended to serve as stimuli for the working memory task and to rate the facial expressions on the degree to which the emotion was expressed and for arousal to obtain a baseline for how children during this age recognize and react to facial expressions. The first study revealed that children rated the facial expressions with similar intensity and arousal across age. When employing the working memory task with facial expressions, results revealed that negatively valenced expressions impaired working memory more than neutral and positively valenced expressions. The ability to successfully complete the working memory task increased between 9 to 12 years of age. Children’s total problems were associated with poorer performance on the working memory task with facial expressions. Results on the effect of emotion on working memory are discussed in light of recent models and empirical findings on how emotional information might interact and interfere with cognitive processes such as working memory. 相似文献

ABSTRACTThe Multifactorial Memory Questionnaire (MMQ) is a participant-reported measure of memory satisfaction, ability, and strategy use. Initially validated with healthy older adults, it has since been used in many different populations and settings for a variety of purposes. We conducted a systematic review and meta-analysis of the measurement properties of the MMQ across multiple, diverse studies. Methods: The study was designed using the Consensus-Based Standards for the Selection of Health Measurement Instruments and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We calculated aggregate statistics and evaluated the methodological quality of 29 studies retrieved from PsycINFO, MEDLINE, EMBASE, and Web of Science. Results: Analyses revealed high-quality evidence for internal consistency, stability, measurement error, convergent validity, and known-groups validity of the three MMQ scales. There was moderate-quality evidence for responsiveness and structural validity, with some studies identifying separate factors for internal and external memory strategy use. Measurement properties were similar across languages, participant samples, and study designs. Conclusions: The MMQ is a valid, reliable, and responsive measure across diverse settings and populations. Future research is needed to determine whether more detailed information can be obtained from the scales, specifically, internal versus external strategy use. 相似文献

The Socratic function of single case studies (SCSs) is described in its relation to the problem of scientific theory development. Contrary to the traditional point of view, the single case study is not a demonstration or verification of theoretical concepts, but a method of their generation and opportunity for analysis of their interrelations. Considering the case study from the perspective of the Socratic function brings to light important conclusions about the ecological validity of theory development. The essential features of the Socratic function are illustrated using the example of the famous Romantic Essays of Alexandr Luria. 相似文献

This study examined the one-year temporal stability and the predictive and incremental validity of the Body, Eating, and Exercise Comparison Measure (BEECOM) in a sample of 237 college women who completed study measures at two time points about one year apart. One-year temporal stability was high for the BEECOM total and subscale (i.e., Body, Eating, and Exercise Comparison Orientation) scores. Additionally, the BEECOM exhibited predictive validity in that it accounted for variance in body dissatisfaction and eating disorder symptomatology one year later. These findings held even after controlling for body mass index and existing measures of social comparison orientation. However, results regarding the incremental validity of the BEECOM, or its ability to predict change in these constructs over time, were more mixed. Overall, this study demonstrated additional psychometric properties of the BEECOM among college women, further establishing the usefulness of this measure for more comprehensively assessing eating disorder-related social comparison. 相似文献

In this article, Vansina's assertions expressed in his comments on my article: \"Fantasies and fairy tales in groups and organizations: Bion's basic assumptions and the deep roles\" (Moxnes, 1998) are refuted. Bion's possible hatred for his parents, his tendency for schizoid isolation, his abandonment of group studies, and his detached leadership style are discussed. The relationship between basic assumptions and deep roles are clarified, and some new ideas about the unconscious in groups and organizations are suggested. It is maintained that access to the unconscious is an age-old function of everyday life and that introspection of the collective unconscious is possible. A fourth basic assumption related to deep roles is proposed, and support for the existence of deep roles in psychodynamic group research is given. 相似文献

Given the increased testing of school-aged children in the United States there is a need for a current and valid scale to measure the effects of test anxiety in children. The domain of children's test anxiety was theorized to be comprised of three dimensions: thoughts, autonomic reactions, and off-task behaviors. Four stages are described in the evolution of the Children's Test Anxiety Scale (CTAS): planning, construction, quantitative evaluation, and validation. A 50-item scale was administered to a development sample (N=230) of children in grades 3–6 to obtain item analysis and reliability estimates which resulted in a refined 30-item scale. The reduced scale was administered to a validation sample (N=261) to obtain construct validity evidence. A three-factor structure fit the data reasonably well. Recommendations for future research with the scale are described. 相似文献

Mindfulness has its roots in Eastern contemplative traditions and is rapidly gaining popularity in Western psychology. However, questions remain regarding the validity of Western operationalizations of mindfulness. Therefore, the purpose of this study was to assess the applicability of several Western mindfulness measures among a sample of Thai Theravāda Buddhist monks. Twenty-four monks recruited from Buddhist temples in Thailand participated in the study. The monks evinced similar associations between mindfulness and related variables as American validation study samples did, and on two facets of mindfulness the monks’ mean scores were greater than an American college student sample. However, the American sample endorsed significantly higher scores on three other facets of mindfulness. These results raise concerns about whether these scales are measuring mindfulness as it is conceptualized in a Buddhist context. Future research with larger samples is needed to further assess the cultural validity and measurement equivalence of Western mindfulness measures across cultural groups. 相似文献
