Of the several tests for comparing population means, the best known are the ANOVA, Welch, Brown–Forsythe, and James tests. Each performs appropriately only in certain conditions, and none performs well in every setting. Researchers, therefore, have to select the appropriate procedure and run the risk of making a bad selection and, consequently, of erroneous conclusions. It would be desirable to have a test that performs well in any situation and so obviate preliminary analysis of data. We assess and compare several tests for equality of means in a simulation study, including non‐parametric bootstrap techniques, finding that the bootstrap ANOVA and bootstrap Brown–Forsythe tests exhibit a similar and exceptionally good behaviour. 相似文献

This study analyzed the psychometric properties of the Career Adapt-Abilities Scale (CAAS) in a Spanish speaking sample and then its relationships with adaptive readiness (i.e., self-regulation), career construction and adapting responses (i.e., vocational coping behaviors), and adaptation results (academic engagement, burnout, and vocational identity). The measures were completed by 577 Spanish university students. The psychometric properties of the newly translated CAAS Spanish Form included internal consistency values ranging from good to excellent for the total score and for the subscales. The results obtained through the confirmatory factor analysis verified the presence of the four CAAS dimensions: concern, control, curiosity, and confidence, which were the same factors observed in other international studies with other languages. The significant correlations obtained between the CAAS and the adaptive readiness, adapting, and adaptation measures confirmed the validity of the CAAS scores. In addition, this study tested a theoretical model of mediation between variables, adding further support to the distinction between the three dimensions leading to adaptation. 相似文献

This study investigated whether men with a history of real-life aggressive, dominant behavior show increases in testosterone and cortisol levels after brief social contact with women. Furthermore, we tested the prediction that such changes in hormones would be larger than those observed previously in young male students. Sixty-seven male participants convicted of intimate partner violence (IPV) either had brief social contact with a female confederate (experimental condition) or a male confederate (control condition). We also performed meta-analyses to investigate whether IPV perpetrators' hormonal responses were larger than the typical responses of young male students in prior studies. All statistical analyses were preregistered. Change in testosterone did not differ across experimental conditions, and testosterone in the IPV perpetrators actually declined from baseline in the female confederate condition. Our meta-analysis showed that this testosterone decrease was different from the testosterone increase typically observed in young male students. The cortisol levels of IPV perpetrators did not change in response to contact with women. This result was consistent with our meta-analysis since young male students also did not experience a cortisol change in response to interactions with women. In sum, our findings provide no evidence that male IPV perpetrators exhibit larger hormone increases to brief interactions with women, although it is possible that the men in this sample did not perceive the social contact period as a courtship opportunity. These results suggest that hormone reactivity to social encounters may differ across subject populations and depend on how subjects perceive social situations within laboratory settings. 相似文献

The purpose of this study was to test an explanatory model of the relationships between physical self-concept and some healthy habits. A sample of 472 adolescents aged 16 to 20 answered different questionnaires assessing physical self-concept, physical activity, intention to be physically active and consumption of alcohol and tobacco. The results of the structural equation model showed that perceived sport competence positively correlated with current physical activity. Body attractiveness positively correlated with physical activity in boys and negatively in girls. Current physical activity positively correlated with the intention to be physically active in the future and negatively with the consumption of alcohol and tobacco. Nevertheless, this last relationship was only significant in boys. The results are discussed in connection with the promotion of healthy lifestyle guidelines among adolescents. This model shows the importance of physical self-concept for engaging in physical activity in adolescence. It also suggests that physical activity is associated with the intention to continue being physically active and with healthy lifestyle habits. 相似文献

Posture-related affordances guide attacks in basketball 总被引:1,自引:0,他引:1

Objectives
The purpose of this study was to investigate the decision made by the attacker to drive to the left or right of the defender.Method
Participants were 32 novice and intermediate basketball players who were assigned the role of attacker or defender in a one-on-one subphase. We manipulated the defender’s posture and measured both the postures of defenders and attackers and the ensuing decision on drive direction.Results
As hypothesized, the posture of defenders guided the decision behavior of the attacker. Both novice and intermediate attackers made the same affordance-based decision by driving to the side of the defender’s most advanced foot, but only when the distance between attacker and defender was small. Moreover, novice attackers conveyed postural information regarding their upcoming drive direction while intermediate attackers were better able to conceal this information.Conclusions
These results lend further support to the notion of information-based control of interpersonal actions in sport contexts. 相似文献347.

In this study, we investigated the associations between body image and psychological well-being, exploring the mediating role
of controlled regulation for entering obesity treatment. In addition, we analyzed whether investment body image was more strongly
associated with controlled regulation (and subsequent well-being) compared to evaluative body image. These analyses were performed
controlling for baseline BMI effects. Participants were 139 overweight women (age: 38.0 ± 6.7 year; BMI: 32.0 ± 4.1 kg/m2) entering treatment. Evaluative and investment body image, controlled regulation, and psychological well-being were assessed.
Body image investment was positively associated with controlled regulation; evaluative body image was not. Controlled regulation
was negatively associated with self-esteem and psychological functioning. Controlled regulation partially mediated the effects
of body image investment on self-esteem, but did not mediate its effects on psychological functioning. Results suggest that
dysfunctional body image investment might undermine well-being within overweight women, partly by increasing controlled regulation
for entering obesity treatment. Discussion focuses on the importance of enhancing body image and autonomy during treatment
to improve well-being and weight outcomes. 相似文献

The aim of this study was to analyze the psychometric properties of two scales that assess the perceived quality and patient satisfaction with outpatient surgery in the Health Service of Murcia. These scales assess the degree of Professional Competence (PC) and Personnel Treatment (PT). The scales were administered to a sample of 2017 users of outpatient surgery in the Health Service of Murcia during the years 2008 and 2009. Exploratory factor analysis indicates a unidimensional structure for each scale. Internal consistency was adequate: .68 for PC and .75 for PT. The correlation between the PC scale and patients' global satisfaction was positive and statistically significant. The correlation between the PT scale and patients' global satisfaction was also statistically significant. The scales have shown their utility to detect areas of improvement and to plan intervention strategies. 相似文献

The study aims to analyze how health is self-perceived by a sample of caregivers of dependant relatives and how it compares with general Spanish population scores. The study also focuses on the relations between self-perceived health and burden. The sample comprised 1,257 caregivers living in Biscay who completed the protocol including sociodemographic data, measures of health-related quality of life (SF-36) and burden (Zarit Burden Inventory). Results show that the health perception of the caregivers taking part into the study reached lower scores in comparison to general Spanish population and that this perception was lower in mental than in physical health. Correlational data supports previous findings indicating that high levels of burden are associated with a worse perception of mental and physical health and provide information on how to guide interventions to improve family caregivers' quality of life. 相似文献

Most studies focusing on the antecedents and consequences of workplace bullying have used a cross-sectional design, which impedes determining the causality of the relationships. In the present work, we analyzed, by means of structural equation models, the relationship between workplace bullying and some variables that are considered antecedents (interpersonal conflicts, role ambiguity, role conflict, and workplace social support) or consequences (health complaints and inclination to absenteeism from work) of this phenomenon. Multicenter study with two phases. The sample consisted of 696 employees from 66 centers. Workplace bullying was assessed by means of the "Mobbing-UNIPSICO" questionnaire, and the other variables with frequency scales. The cross-sectional models indicated a significant association between role conflict, workplace social support, and workplace bullying in both study periods. Concerning the longitudinal relationships, only workplace social support was a significant predictor of workplace bullying, which, in turn, was a cross-sectional and longitudinal predictor of workers' health complaints. Our results show the mediating effect of workplace bullying between certain work conditions and health complaints, and it is recommendable to replicate these findings in a multi-occupational sample. 相似文献
