This study evaluated the extent to which two youth measures of Type A behavior--the Matthews Youth Test for Health (MYTH) and the Hunter-Wolf A-B Rating Scale--similarly assess the Type A construct. Data from 25 elementary teachers and from 300 of their students revealed that these scales are weakly correlated and that the concordance of their Type A-Type B classifications was only slightly above that expected by chance. Weak agreement was found even when teachers and students rated the same Type A behaviors, which suggests that variability in content was not the principal reason for the lack of agreement between these measures. The major implication of this study is that the MYTH and the Hunter-Wolf scale should not be considered interchangeable measures of Type A behavior. The study reveals that investigators' choice of a Type A measure may strongly affect the nature of their research findings and may inhibit the integration of their data with data from other investigators who employ different measures of the Type A construct. It is recommended that, if multiple measures cannot be used in a study, the investigator employ the MYTH.  相似文献

The present study examined college students' (86% white) reactions to scenarios of three types of domestic violence situations. Subjects read a brief newspaper report of a battering incident and afterwards rated the situation and participants on a variety of scales. The scenario described either a (1) husband battering his wife, (2) wife battering her husband, or (3) gay male battering his lover. In addition, there was or was not an apparent verbal provocation by the victim. Results showed the harshest evaluation of a batterer who was not provoked. A greater responsibility was placed on the victim in the battered husband scenario, which generally was taken less seriously than the battered wife case. Results suggest the need to examine a diversity of battering situations and variables in order to fully understand attributions made about such situations.  相似文献

Just over two hundred telephone sales staff completed the Eysenck Personality Inventory (EPI) and Honey and Mumford's Learning Styles Questionnaire (LSQ). Extraversion was highly correlated both positively and negatively with three of the four LSQ measures. The lie scale from the EPI was also systematically correlated with the Activist and Reflector scales of the LSQ. Both the EPI and LSQ traits were modestly correlated with two criteria: ratings of Actual Performance and Development Potential. Regressions were used to determine the best predictors of the two ratings measures. Personality variables (extraversion, neuroticism) and certain learning styles (reflector, pragmatist) were statistically significant predictors of rated performance, though they accounted for less than 10% of the explained variance. The results concur with recent meta-analytical studies that show personality variables account for a small but important amount of variance in measures of work performance.  相似文献

This article illustrates stages of group development in a semi-structured team meeting of staff and patients in an inpatient psychiatric unit. Clinical material drawn from such a group at the Massachusetts Mental Health Center is presented in support of the view that, even in a rapid-turnover ward, group process in a mixed-level, mixed-diagnosis "ward meeting" follows some predictable lines and responds to the articulation of certain predictable concerns. Garland's (1981) model of group development is adapted to show the cyclical nature of group process in a teaching hospital, where doctors as well as patients may make only brief stays. Effective leadership strategies are suggested.  相似文献

Estimates of perceived and ideal body size were collected in 216 boys and girls ages 6 through 14 years. Video methodology was used to adjust the width of a life-size frontal image of the children. Longitudinal data were collected annually for three years, beginning at ages 6, 9, and 12. Three psychological methods were used, including the method of adjustment, staircase method, and adaptive probit estimation technique which permitted separate measures of the children's point of subjective equality and just noticeable difference values. The point of subjective equality is the body size which is subjectively equal to the child's perception of self. The just noticeable difference is the amount of change in body size necessary to detect the difference 50% of the time. Acceptable size boundaries were also measured, using the method of adjustment. Over-all, children were accurate in estimating their body width, with average overestimation of less than 2%. Overestimation decreased within each age group during the three years of the study. There were no differences between ages or sexes. Both point of subjective equality and just noticeable difference values decreased significantly during the three years of the study. The latter values significantly decreased as children became older. Body dissatisfaction (the discrepancy between perceived and ideal size) remained low for boys in all age groups. Girls' body dissatisfaction significantly increased across ages, beginning at age 9. Test-retest consistency of both perceived and ideal size judgments at intervals of one and two years were low. Acceptable boundaries in body width were similar between sexes and across age cohorts.  相似文献

The present investigation replicates Jackson and McGill's study (1996) and extends it by considering the effects of respondents' own height, weight, and body mass on perceptions of attractiveness. Results, although generally supportive of those found by Jackson and McGill, point to the influence of respondents' own physical characteristics in the process of perceptions of attractiveness: only 1 of Jackson and McGill's 3 (of a possible 19) differences between responses of African- and Euro-American women was corroborated (the importance of silky hair for Euro-American women), whereas a second difference (the importance of round buttocks for African-American women) disappeared when controlling for respondents' weight, height, and body mass. Although differences between the two investigations may be attributed to regional differences in the surveyed students (Michigan and North Carolina), the small effect of one's own weight, height, and body mass in assessing an other-sex person's attractiveness may reflect adherence to norms learned very early in life that are subject to regional variations.  相似文献

Tourette syndrome (TS) is a neurological disorder of childhood onset that is characterized by the occurrence of motor and vocal tics. TS is associated with cortical-striatal-thalamic-cortical circuit [CSTC] dysfunction and hyper-excitability of cortical limbic and motor regions that are thought to lead to the occurrence of tics. Individuals with TS often report that their tics are preceded by ‘premonitory sensory/urge phenomena’ (PU) that are described as uncomfortable bodily sensations that precede the execution of a tic and are experienced as a strong urge for motor discharge. While the precise role played by PU in the occurrence of tics is largely unknown, they are nonetheless of considerable theoretical and clinical importance as they form a core component of many behavioural therapies used in the treatment of tic disorders. Recent evidence indicates that the cingulate cortex may play an important role in the generation of PU in TS, and in ‘urges-for-action’ more generally. In the current study, we utilized voxel-based morphometry (VBM) techniques, together with ‘seed-to-voxel’ structural covariance network (SCN) mapping, to investigate the putative role played by the cingulate cortex in the generation of motor tics and the experience of PU in a relatively large group of young people with TS. Whole-brain VBM analysis revealed that TS was associated with clusters of significantly reduced grey matter volumes bilaterally within: the orbito-frontal cortex; the cerebellum; and the anterior and mid-cingulate cortex. Similarly, analysis of SCNs associated with bilateral mid- and anterior cingulate ‘seed’ regions demonstrated that TS is associated with increased structural covariance primarily with the bilateral motor cerebellum; the inferior frontal cortex; and the posterior cingulate cortex.  相似文献

The present article examines how job demands and resources are related to indices of strain among healthcare professionals during virus pandemics. The article also presents the results of a study examining the relationships between COVID-19 demands (e.g., lack of personal protective equipment, concerns about infecting family members), resources (meaningful work, social support), and mental health strain within a sample of emergency medicine personnel over six consecutive weeks. COVID-19-related demands and hours worked were hypothesized to be positively related to mental health strain, whereas meaningful work and social support were hypothesized to be negatively related to mental health strain. Hours worked the prior week were hypothesized to exacerbate the positive relationships between COVID-19 demands and mental health strain, whereas the resources of meaningful work and social support were expected to buffer the relationships. Multilevel models controlling for mental health strain the prior week revealed that COVID-19 demands, along with hours worked, were each related to higher mental health strain during the week. Hours worked magnified the within-person relationship between personal COVID-19 demands and mental health strain. In contrast to the hypotheses, social support and meaningful work were not related to mental health strain. Discussion focuses on the implications of the findings for healthcare professionals.  相似文献
