This article describes the development of a questionnaire that assesses problems in adapting to chronic skin disorders, the Adjustment to Chronic Skin Diseases Questionnaire. Patients (N = 442) with different skin disorders completed the original item pool. Principal-components analysis suggested a 6-factor solution that was largely replicated with 2 additional samples of 192 patients with psoriasis or atopic dermatitis and 165 patients with atopic dermatitis. Four of the subscales showed very good internal consistencies, retest reliabilities, and sufficient correlations with expert ratings: Social Anxiety/Avoidance, Itch-Scratch Cycle, Helplessness, and Anxious-Depressive Mood. Two short additional subscales, Impact on Quality of Life and Deficit in Active Coping, showed moderate internal consistencies, but good retest reliabilities. Correlations of the subscales with measures of depression, anxiety, and coping, and meaningful differences between dermatological subgroups support their construct validity. A treatment study showed that changes in some of the subscales correlated with changes in the severity of the skin condition.  相似文献

In the literature on motor control, three theoretical perspectives on the relation between discrete and cyclical movements may be discerned: (a) cyclical movements are concatenated discrete movements; (b) discrete movements are a limiting case of cyclical movements, and (c) discrete and cyclical movements are motor primitives that may be combined but are irreducible to each other. To examine the tenability of these perspectives, 16 participants performed cyclical and discrete (flexion and extension) reaching movements of various amplitudes to differently sized targets. The kinematic properties of the recorded movements were analyzed and compared in detail. The cyclical, ongoing movements differed markedly from the discrete movements as well as from the first and last half-cycles of a bout of cyclical movements, especially in terms of their symmetry ratio. These effects were largely independent of amplitude, target size and movement direction (flexion-extension). The results obtained ruled out perspective (a) and, in principle, left open perspectives (b) and (c). However, the observed kinematic features were not readily accounted for by the specific dynamical models that have been proposed under perspectives (b) and (c). Future modeling attempts should explicate the dynamics of initiation and abortion of both discrete and cyclical movements.  相似文献

There is considerable evidence implicating heart-beat perception (HBP) accuracy and anxiety sensitivity (AS) in the development of panic in adults. However, to date there have been no studies exploring the association between HBP, AS and childhood panic/somatic symptoms. Seventy-nine children aged 8 to 11 years completed a mental tracking paradigm (Psychophysiology 18 (1981) 483) to assess HBP, the Children's Anxiety Sensitivity Index (J Clin Chil Psychol 20 (1991) 162) and the Screen for Childhood Anxiety Related Emotional Disorders (J Am Acad Child Adoles Psych 38 (1999) 1230). Those with good HBP (n = 7, 9%) had significantly higher panic/somatic symptoms (t = -1.71, P < 0.05), and AS (t = -2.16, P < 0.02) than those with poor HBP. There were no effects of age, sex or BMI on HBP. Those with high levels of panic/somatic symptoms were seven times more likely to have good HBP and had AS scores 1 S.D. higher than the remainder of the sample. Multivariate analyses revealed that these two phenotypes had independent associations with high panic/somatic symptoms. These results extend the literature on HBP and panic and suggest that in children, as in adults, increased panic/somatic symptoms are associated with enhanced ability to perceive internal physiological cues, and fear of such sensations.  相似文献

Variations in support for affirmative action were assessed in a sample of 181 African American college students in Massachusetts. These students generally endorsed affirmative action, and endorsement varied positively as a function of the belief that one had personally benefited from affirmative action. Aspects of racial identity, indexed by the Multidimensional Inventory of Black Identity, also predicted variations in attitudes toward affirmative action, over and above background factors and personal benefit. Consistent with realistic group conflict theory, the most influential aspects of identity were centrality (i.e., the degree to which group identity is central to personal identity), private regard (i.e., pride in the group), and an oppressed minority ideology (i.e., a viewpoint that emphasizes the similarities between African Americans and other oppressed groups).  相似文献

This study evaluates how different aspects of travel socialization during childhood and adolescence contribute to the explanation of travel mode choice in young adulthood. In an online survey with 2612 students who had access to a car three different socialization aspects were measured retrospectively: communication with parents about the environmental impact of travel mode choice at the participants’ age of 15, the symbolic-affective importance of driving and acquisition of a driver’s license at the age of 18, and finally multi-mobility in the peer group at the age of 18. It was expected that socialization constructs would have a direct effect on social and personal norm as wells as on car use habit and an indirect effect on car use, mediated by norms, habit and intention. Structural equation modelling showed a significant impact of all socialization constructs on either norms or car use habit or both. Moreover, the postulated mediator effect could be confirmed. The paper encourages widening the perspective of transport studies by aspects of socialization, which have been neglected in former research on adults mobility behaviour.  相似文献

ObjectivesTaking into account the need for applied research on the most effective ways to prepare Olympians psychologically, the first purpose of this study was to gain more insight into the changes perceived by four athletes in view of their participation in the 2008 Beijing Olympic Games. The second purpose of this study was to illustrate how using a holistic and dynamic approach to the identification of the perceptions of these athletes' Olympic experiences can provide information relevant for the provision of individual ASP support to these athletes.DesignUsing a prospective design athletes' perceptions of changes were gathered prior, during as well as after the Olympic Games.MethodsA combination of interview (pre and post Olympic Games) and self-reporting (during Olympic Games) was used to describe athletes' perceptions of changes occurring at athletic, psychological, psychosocial, academic/vocational level.ResultsResults confirmed in first instance athletes' perceptions of the multifaceted nature of their Olympic experience. In second instance, the use of a dynamic and holistic perspective allowed to identify that participants perceived (a) during the phase prior to the Olympic Games 14 changes at all four levels, (b) during the Olympic Games eight changes at three levels, and (c) during the phase after returning from the Olympic Games 11 changes having occurred at four levels.ConclusionsThis study showed the usefulness of using a dynamic and holistic perspective not only in order to identify athletes' perceptions of their Olympic experiences, but also to enhance ASP practitioners' knowledge on the needs for a holistic and dynamic ASP-support provision. In this way, the effectiveness and efficiency of ASP practitioners working with athletes preparing for, or competing at the Olympic Games could be enhanced.  相似文献

The objective of this study was to examine the psychometric properties of the Autobiographical Memory Test (AMT), which is widely used to measure overgeneral autobiographical memory in individuals with depression and a trauma history. Its factor structure and internal consistency have not been explored in a clinical sample. This study examined the psychometric properties of the AMT in a sample of recent trauma survivors (N = 194), who completed the AMT 2 weeks after a trauma. Participants were also assessed with structured clinical interviews for current acute stress disorder and current and past major depressive disorder. Confirmatory factor analysis and item response theory were used to analyze the AMT in the whole sample. The factor structure of the AMT was also compared for (a) individuals with and without lifetime major depressive disorder and (b) individuals with current (posttrauma) major depressive disorder and/or acute stress disorder versus those with neither disorder. In all of these analyses, the AMT with cues of positive and negative valence had a 1-factor structure, which replicates work in nonclinical samples. Based on analyses of the whole sample, scores from the AMT had a reliability estimate of .72, and standard error of measurement was lowest for people who scored low on memory specificity. In conclusion, the AMT measures 1 factor of memory specificity in a clinical sample and can yield reliable scores for memory specificity. More psychometric studies of the AMT are needed to replicate these results with similar and other clinical populations.  相似文献

In this study, we examined the extent to which preschool children were able to understand pans (continuous sideward shifts of a scene generated by rotating the camera around a virtual axis), one of the most typical technical elements of films. This was done by showing 60 participating children a film in which a teddy bear asked them questions about pan sequences. The questions could be answered correctly only if the underlying pan was understood. The study revealed that the increase in the children's comprehension of the pans was significantly correlated with age and was facilitated by gains in visual working memory (VWM). It was found that VWM in 3 year olds is generally so low that they are still not able to understand any pan sequences. Most of the pans were understood by those children who could remember the locations of two simple objects. This VWM level is sex dependent and is usually reached by boys at age 4 and by girls at age 5; thus, boys understand pans quite a bit earlier. Perception speed, pan speed, and television consumption played rather limited roles. An appropriate model for the understanding of pans is subsequently introduced and discussed.  相似文献

Most research on formal child care and children’s outcomes has focused on single countries. We, however, contend that policy context may moderate the association between formal child care characteristics and children’s socioemotional well-being. We examined this by comparing the Netherlands, Finland and the UK; three countries that differ regarding family policies. Of these three countries, Finland was recently ranked highest (ranked 1st) with regards to quality of child care in a recent analysis by the Economist, followed by the UK (ranked 3rd) and then the Netherlands (ranked 7th). We hypothesized that children who attend child-care settings in countries with higher-quality formal child-care provision would generally show better socioemotional outcomes. Data from the comparative ‘Families 24/7’ survey were used, including 990 parents with children aged 0–12. We distinguished between two age groups in our analysis. Results indicated that, compared to the UK, longer hours in formal care were less beneficial in the Netherlands. Furthermore, spending time in formal care during nonstandard hours was more harmful for children in Finland compared to the UK. Lastly, receiving care from multiple caregivers was more disruptive for British children than for Dutch children. No differences were found between Finland and the Netherlands.  相似文献
