Costa and McCrae's operationalization of the Five-Factor Model, the Neuroticism, Extraversion, and Openness Personality Inventory—Revised (NEO-PI-R; Costa and McCrae, 1992a), measures five broad dimensions of personality: Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness. According to Costa and McCrae, the Neuroticism (N) domain scale subsumes six facets. Although derived rationally and tested factor analytically, the factorial structure of the facet scales has yet to be unequivocally confirmed with analytic methods imposed at the item level. Using confirmatory and exploratory factor-analytic techniques, this study examines and tests the structure of the N domain scale of the NEO-PI-R. Confirmatory factor analysis indicates poor replication of the structure of the N scale. Results of the exploratory factor analysis indicate that while three of the facets replicated quite well, the other three factors did not correspond to Costa and McCrae's formulation. Future research should elaborate on the factorial structure and construct validity of the N facet scales, especially if they are to be used and interpreted in personality and clinical assessment. © 1997 by John Wiley & Sons, Ltd. 相似文献

Adherence to medical treatment is a significant problem for children and adolescents with chronic conditions, such as asthma, diabetes, and cystic fibrosis. The consequences of nonadherence can be serious, contributing to increased symptoms, unnecessary hospitalizations, and declines in physical functioning. The quality of data obtained from clinical trials can also be affected by poor adherence, leading to erroneous conclusions concerning the efficacy of drug treatments and the dosages that are needed to achieve those effects. Adherence problems in both clinical research and practice also lead to substantially higher health care costs. In order to further our understanding of the barriers that lead to poor adherence and identify strategies that are effective in addressing them, we need to develop reliable and valid measures of adherence behaviors. Using cystic fibrosis as a model of a serious, chronic disease that requires a difficult and time-consuming medical regimen, three different types of adherence measures are considered: self-report questionnaires, daily diary reports, and electronic monitors. The specific advantages and disadvantages of each type of measurement are reviewed, and specific recommendations are made for future research. 相似文献

This study investigated predictions of the life-span theory of selection, optimization, and compensation, focusing on different patterns of task priority during dual-task performance in younger and older adults. Cognitive (memorizing) and sensorimotor (walking a narrow track) performance were measured singly, concurrently, and when task difficulty was manipulated. Use of external aids was measured to provide another index of task priority. Before dual-task testing, participants received extensive training with each component task and external aid. Age differences in dual-task costs were greater in memory performance than in walking, suggesting that older adults prioritized walking over memory. Further, when given a choice of compensatory external aids to use, older adults optimized walking, whereas younger adults optimized memory performance. The results have broad implications for systemic theories of cognitive and sensorimotor aging, and the costs and benefits of assistive devices and environmental support for older populations. 相似文献

The UK is reported to have the highest rate of self-injurious behaviour (SIB) in Europe. It is no longer underrepresented in adolescent male populations, and further appears to correlate significantly with the increase in young male completed suicides. Early research suggested mental health professionals view males as being psychologically healthier than females. Gender differences in behavioural presentation and conceptual understanding of SIB may account for such disparity. The fields of counselling psychology and psychotherapy are in the advantageous position of embracing broader perspectives in which to challenge methodological and conceptual biases within existing medical frameworks. Differential gender biases in the nosology of comorbid conditions, psychodiagnosis, and treatment decisions are identified. Mental health workers across disciplines continue to find the management of SIB a challenge despite the wealth of theoretical models available to inform practice. Some techniques and promising therapies (dialectical behaviour therapy and problem-solving therapy) are highlighted as practicable approaches for counselling psychologists. Conclusions reveal future research may benefit from incorporating broader definitions of SIB expressed across the sexes. Further investigation into treatment efficacy with particular emphasis on the impact of gender role socialization is also indicated. 相似文献

Differences in mothers’ parenting behaviors toward their identical twin preschoolers were examined to identify nonshared environmental processes in social‐emotional development. The study included 62 pairs of 3½‐year‐old same‐sex identical twins. Indicators of each child’s social‐emotional development (temperament, prosocial behavior, behavior problems and noncompliance) and parenting environment (warmth and negativity, positive and negative control, responsiveness) were assessed using observers’, interviewers’, and parents’ ratings. Mothers treated their identical twins differently, and this differential treatment covaried in expected ways with identical twin differences in social‐emotional adjustment. The twin who received more supportive and less punitive forms of parenting was also higher in positive mood and prosocial behaviors and lower in negative mood and behavior problems when compared to her or his twin. 相似文献

Bowker's test for marginal equality in contingency tables provides a familiar chi-square test to determine whether the marginal distributions are the same across two or more factors or occasions. In this note it is shown how latent trait theory provides a theoretical framework for the development and application of this test.The research reported here was supported by a grant to the senior author from the National Institute on Aging (AG03164). 相似文献

When presented a series of patterns inside a frame, subjects unintentionally retained information concerning the frame-relative location of the elements composing the patterns; they could use this superficial information to estimate the frequency with which the elements occurred at various locations within the frame. There were two aspects of the results that supported the hypothesis that this superficial element-location information was abstractively encoded and, therefore, retrievable independent of the patterns comprising the elements: (1) Correlations between actual and estimated frequency remained significant after the effects of pattern recall were partialled out, and (2) correlations were enhanced by assuming that the frequency estimate for each location was affected by the imprecise coding of position for elements falling in surrounding locations. Additional experiments indicated that an orienting task emphasizing pattern recall resulted in very inaccurate estimation of element-location frequency, and intentional instructions improved the precision of position coding for individual elements. 相似文献

In two experiments, we explored the degree to which sentence context effects operate at a lexical or conceptual level by examining the processing of mixed-language sentences by fluent Spanish-English bilinguals. In Experiment 1, subjects’ eye movements were monitored while they read English sentences in which sentence constraint, word frequency, and language of target word were manipulated. A frequency × constraint interaction was found when target words appeared in Spanish, but not in English. First fixation durations were longer for high-frequency Spanish words when these were embedded in high-constraint sentences than in low-constraint sentences. This result suggests that the conceptual restrictions produced by the sentence context were met, but that the lexical restrictions were not. The same result did not occur for low-frequency Spanish words, presumably because the slower access of low-frequency words provided more processing time for the resolution of this conflict. Similar results were found in Experiment 2 using rapid serial visual presentation when subjects named the target words aloud. It appears that sentence context effects are influenced by both semantic/conceptual and lexical information. 相似文献
