Abstract

The purpose of this study was to ascertain coping styles among competitive athletes in response to various acute stressors. Specifically, the authors used a 134-item survey to measure approach and avoidance coping styles, with task-focused and emotion-focused coping tendencies nested hierarchically as subdimensions under each. Australian and U.S. college-aged participants indicated the extent to which they used approach, avoidance, task-focused, and emotion-focused coping strategies (a 4-factor model) in response to selected acute stressors experienced during sport competition. The authors computed confirmatory factor analysis to test the theoretically driven model. The criterion loading of .30 and above for each of the factors reduced the survey to 65 items. Findings indicated stronger links between the 2 approach constructs of task- and emotion-focused coping than between the 2 avoidance constructs of those subdimensions. The goodness-of-fit indices for the 4-factor model were 0.58 and 0.57 for Australian and U.S. samples, respectively, and .71 overall. Concomitant low correlations between the 2 approach (0.18) and the 2 avoidance dimensions (0.43) reflected relatively high residuals between stressors. In general, psychometric analyses suggest that coping style may be more prevalent in some situations than others, lending partial support for the transactional model of coping.  相似文献

二参数逻辑斯蒂模型项目参数的估计精度   总被引:1,自引:0,他引:1  
项目参数的估计精度对于测验的编制尤其是题库的建立十分重要。目前,国内外对项目参数估计精度的研究,大部分是基于在已知项目参数真值的情况下,运用各种参数估计方法产生新的估计值,再和真值进行偏度(BIAS)和均方根差(RMSE)的比较,从而说明该种估计方法的有效性。但是这种方法不能提供不同的参数真值之间的估计误差的变化规律。为了弥补这一缺陷,本文尝试从项目参数估计信息函数的角度出发研究项目参数的估计精度问题。本研究以二参数Logistic模型作为研究对象,首先定义了项目参数的估计信息函数,然后基于完全随机实验设计,通过模拟研究的方法探索影响项目参数的估计精度的因素,实验共设计了(2×3×2)种情形。研究结果表明:(1)项目参数(a,b)的估计精度均随着被试样本量的增大而提高;(2)被试的能力分布对难度参数的估计精度影响较大,对区分度参数的估计精度影响相对较小;(3)难度参数和区分度参数的估计精度都分别受到参数a和参数b的共同作用。  相似文献

The purpose of this study was to explore the process by which emotional abuse occurs and is often sustained in sport. Methods were established in congruence with the iterative nature of grounded theory. In total, 18 retired elite athletes participated in the study. In-depth semistructured interviews were conducted with each participant, and data were coded using open, axial, and selective coding techniques. Data were interpreted to suggest that the perpetration of emotional abuse in the coach–athlete relationship is closely tied to ambitions and philosophies of athlete development. Based on the findings, an ecological transactional model of vulnerability to emotional abuse in the coach–athlete relationship is proposed. Recommendations are made for future prevention and intervention initiatives.  相似文献

Abstract

Previous research indicates the viability of a distinction between cognitive and somatic components of the anxiety response, and multidimensional anxiety scales have proven useful in relating cognitive and somatic anxiety to behavioral outcomes. This article describes the development and validation of a sport-specific measure of cognitive and somatic trait anxiety. The Sport Anxiety Scale measures individual differences in Somatic Anxiety and in two classes of cognitive anxiety, Worry and Concentration Disruption. Both exploratory and confirmatory factor analyses supported these dimensions in several different athlete samples. Psychometric properties of the Sport Anxiety Scale are described, as are its relations with other psychological measures and with precompetition affective state measures. In the last of the four studies reported, scores on the Concentration Disruption scale were negatively related to the performance of college football players over the course of a season. The studies suggest that the Sport Anxiety Scale may be useful in defining sport-related anxiety more sharply and assessing how the cognitive and somatic anxiety components relate to performance and other outcome measures in sport.  相似文献

Previous studies have shown how social networks lead athletes to accept pain as a “part of the game,” which generates pressure on athletes to continue competing despite being in pain. Little is known, however, about the potential coping strategies that are related to pain behavior in sport. This study of 205 combat athletes examined whether pain coping strategies, including distraction from pain, praying, reinterpreting pain sensations, ignoring pain, and pain catastrophizing, are related to athletes’ inclination to play through pain. Results revealed that pain catastrophizing led athletes to reduce their physical involvement in their sport activity. Of particular interest was the moderating effect of ignoring pain such that ignoring pain significantly attenuated the negative effect of pain intensity on athletes’ inclination to play through pain. Few studies have tested and supported the contribution of pain coping to the prediction of behavior in real sport situations. By identifying which coping strategies athletes could use to maintain their physical involvement despite being in (sometimes intense) pain, the current study makes an important contribution for tailoring pain management programs for this at-risk population.  相似文献

The objective of this study was to determine whether the sport psychological profiles of talented 13-year-old sport participants differ from less talented participants. 162 grade 8 learners with a mean age of 13.2 ± 0.33 years voluntarily participated in the study. The participants were subjected to the Australian Talent Search protocol and completed the Athlete Coping Skills Inventory for Sport (ACSI-28). The group was categorize according to the median of all the tests of the talent identification protocol (TID) in a talented (TG) and a less talented group (LTG). The TG obtained higher means in all seven sport psychological characteristics: coping with adversity, peaking under pressure, goal setting, confidence, coachability and the average coping profile, concentration and freedom from worry. The results indicate that talented adolescents exhibit specific sport psychological characteristics compared to less talented adolescents.  相似文献

This study aimed to investigate whether differences exist in the personality profiles of professional and semi-professional rugby union players. Participants were 73 male rugby players, 52 professional players and 21 semi-professional players. All participants completed the NEO Five-Factor Personality Inventory (NEO-FFI) as part of the WebNeuro Sport online assessment. An independent sample t-test showed a statistically significant difference in neuroticism between the professional and semi-professional players. The magnitude-based inference method confirmed the results of the independent sample t-test with a moderate effect. The potential practical value of these findings is that the Neuroticism scale of the Big Five personality dimensions can be used as a screening tool for indicating which players a team would want to recruit and invest time and money in since these players will most likely be capable of progressing to the top level in their sport.  相似文献

The manipulation of small objects requires continuous contributions from both predictive and reactive mechanisms. The authors aimed to study the development of predictive and reactive mechanisms used by children from 6 to 14 years of age to manage impulsive loading. The load of a handheld object was increased rapidly by the drop of a weight hung on the object. The drop was triggered either by the child (predictive condition) or by the examiner (reactive condition). Regardless of the condition, the control strategy was refined with age. Younger children were unable to adapt their grip force (GF) to the friction of their fingers, whereas the older children provided GF that was well adapted to their variable coefficient of friction, thereby producing a secure grip. This reflected either an inadequate amount of force or an inability to integrate cutaneous information from the fingers in younger children. Additionally, a modulation with age for both predictive and reactive mechanisms was observed. All together, the better predictive abilities and the more secure grip exhibited by older children allow decreased slipping and improved performance in an impulsive loading task.  相似文献

Performance errors drive motor learning for many tasks. The authors' aim was to determine which of two strategies, method of amplification of error (MAE) or direct instruction (DI), would be more beneficial for error correction during a full golfing swing with a driver. Thirty-four golfers were randomly assigned to one of three training conditions (MAE, DI, and control). Participants were tested in a practice session in which each golfer performed 7 pretraining trials, 6 training-intervention trials, and 7 posttraining trials; and a retention test after 1 week. An optoeletronic motion capture system was used to measure the kinematic parameters of each golfer's performance. Results showed that MAE is an effective strategy for correcting the technical errors leading to a rapid improvement in performance. These findings could have practical implications for sport psychology and physical education because, while practice is obviously necessary for improving learning, the efficacy of the learning process is essential in enhancing learners' motivation and sport enjoyment.  相似文献
