ObjectivesTo provide initial evidence for the construct, concurrent, and predictive validity of the Team-Referent Attributions Measure in Sport (the TRAMS).DesignCross-sectional in Studies 1 and 2, and multiple time points in Study 3.MethodStudy 1 required participants (N = 500) to complete the TRAMS for their “least successful” and “most successful” performances in the preceding three months. In Study 2, after performance, participants (N = 515) completed the TRAMS and the Causal Dimension Scale for Teams (CDS-T; Greenlees et al., 2005). Study 3 required participants (N = 165) to complete a measure of pre-competition collective-efficacy prior to performance (Day 1, Time 1), the TRAMS following performance (Day 1, Time 2), and a measure of subsequent collective-efficacy prior to subsequent performance (Day 7–9, Time 3).ResultsStudy 1 supported the factor structure of the TRAMS across least successful and most successful conditions. Study 2 provided further support for the factor structure of the TRAMS, together with evidence of concurrent validity with subscales of the CDS-T. Study 3 revealed, following team defeat, interactions between controllability and generalisability dimensions: Controllability had a significant effect upon subsequent collective-efficacy when causes of team defeat were also perceived to generalise across situations and/or across teams. Following team victory, stable attributions were positively associated with subsequent collective-efficacy.ConclusionsThis article provides initial evidence for the validity of the TRAMS and demonstrates for team-referent attributions the theoretical advantages of examining a broader conceptualisation of generalisability attributions and interactive effects of attributions.  相似文献

This article presents information on the development and initial validation of the 16-item Response to Intervention (RTI) Beliefs Scale. The scale is designed to measure the extent to which educators working in schools hold beliefs consistent with the tenets of RTI. The authors administered the instrument to 2,430 educators in 62 elementary schools in the fall of 2007 and 2,443 educators in 68 elementary schools in the spring of 2008. Exploratory, single-level confirmatory, and multilevel confirmatory factor analysis procedures were used to examine construct validity. Results supported a correlated 3-factor model (Academic Abilities and Performance of Students with Disabilities, Data-Based Decision Making, and Functions of Core and Supplemental Instruction) at both the school and educator levels of analysis. Furthermore, the factor scores derived from the model demonstrated significant, positive relations to RTI implementation. Reliability estimates for two of the three factor scores exceeded.70. Implications for research on educator beliefs and implementation of RTI as well as implications for school psychologists supporting RTI implementation are discussed.  相似文献

Previous observations of a New Caledonian crow (Corvus moneduloides) spontaneously bending wire and using it as a hook [Weir et al. (2002) Science 297:981] have prompted questions about the extent to which these animals 'understand' the physical causality involved in how hooks work and how to make them. To approach this issue we examine how the same subject ("Betty") performed in three experiments with novel material, which needed to be either bent or unbent in order to function to retrieve food. These tasks exclude the possibility of success by repetition of patterns of movement similar to those employed before. Betty quickly developed novel techniques to bend the material, and appropriately modified it on four of five trials when unbending was required. She did not mechanically apply a previously learned set of movements to the new situations, and instead sought new solutions to each problem. However, the details of her behaviour preclude concluding definitely that she understood and planned her actions: in some cases she probed with the unmodified tools before modifying them, or attempted to use the unmodified (unsuitable) end of the tool after modification. Gauging New Caledonian crows' level of understanding is not yet possible, but the observed behaviour is consistent with a partial understanding of physical tasks at a level that exceeds that previously attained by any other non-human subject, including apes.  相似文献

The General Health Questionnaire (GHQ) is a self-report questionnaire designed to identify psychological distress. Psychometric properties of two versions of GHQ-12 and GHQ-20 were assessed in a large population-based sample of Finnish twins, ages 22 to 27 (n= 4580). Participants were randomized into two subgroups, namely Twin1 (n= 2294) and Twin2 (n= 2286). The GHQ-12 data were assessed using Confirmatory Factor Analysis (CFA). The factor structure of the GHQ-20 was first assessed with Exploratory Factor Analysis (EFA) in the Twin1 dataset, and the results obtained were then subjected to CFA in Twin1 and Twin2 datasets. The CFA of the GHQ-12 indicated that the best fit and the simplest solution were provided by the three-factor solution in both subpopulations. Analyses of the GHQ-20 suggested that the four-factor structure was superior to the three-factor model. This result is also theoretically justifiable. Compared to the 12-item version, GHQ-20 provides additional fourth factor of anhedonia, suggesting some discriminative power.  相似文献

This study investigated whether facilitating a benign interpretive bias decreases negative thought intrusions in generalized anxiety disorder (GAD). Clients were randomly allocated to an interpretation modification condition in which they repeatedly accessed benign meanings of emotionally ambiguous homographs and scenarios, or to a control condition in which they accessed threat and benign meanings with equal frequency. Worry frequency was assessed using a breathing focus task that involved categorising the valence of thought intrusions before and after an instructed worry period. Interpretation bias was assessed during the modification tasks, and on a different measure of interpretation bias (sentence completion) following a period of worry. The experimental procedure modified interpretations made during training, and in the later sentence completion task. Furthermore, compared to the control group, the benign group showed fewer negative thought intrusions during breathing focus (as rated by both participants and an assessor). These findings show that it is possible to induce a more benign interpretive bias in GAD clients and that this reduces negative thought intrusions.  相似文献

In this experiment we investigated the effect of different instructions on the modification of attentional biases, and subsequently on worry persistence. Participants without excessive worry completed a modified dot-probe task, designed to train attention either to threat or neutral words. Half of each group was given explicit instructions regarding the relationship between word valence and target location, and half were given the more usual minimal instructions. Impact on worry persistence was assessed by categorizing the valence of thought intrusions before and after a period of instructed worry. Response latencies to test items on the dot-probe task showed that attention had been successfully manipulated in the expected direction, and explicit instructions led to more effective attention modification. Moreover, participants in the attend-threat group who received explicit instructions reported significantly more negative thought intrusions following instructed worry, as rated by an assessor, whereas participants in the attend-neutral group did not. These findings suggest that an attentional bias towards threatening information plays a role in worry persistence, and that explicit instructions may be helpful in modifying this bias.  相似文献

《大学生主观幸福感量表》的编制   总被引:10,自引:0,他引:10  
根据国内外关于主观幸福感的文献和已有的研究经验,编制了大学生主观幸福感问卷。以往大多数研究认为,主观幸福感由生活满意度和情绪体验两个基本成分构成,本研究认为主观幸福感还应包括社会性行为和人际关系等成分。对376名大学生进行初测,通过探索性因素分析,表明大学生主观幸福感由自我满意、家庭满意、消极情绪、积极情绪、精力、生活满意、社会性行为和人际关系8个维度构成,共41个项目。对511名大学生施测41个项目的主观幸福感问卷,进行验证性因素分析,结果表明,上述结构是合理的。  相似文献

Factor analyses were conducted on scores from the Reynolds Adolescent Adjustment Screening Inventory (RAASI; Reynolds, 2001 ) representing at‐risk Latino youth. The 4‐factor model of the RAASI did not exhibit a good fit. However, evidence of generalizability for Latino youth was noted.  相似文献
