Neuropsychologists are increasingly asked to make judgments regarding treatment options and rehabilitation strategies in addition to evaluating the degree and scope of neuropsychological impairment following acquired brain injuries. The capacity to make informed clinical decisions relies upon research investigating the relationships between neuropsychological and psychosocial status (i.e., ecological validity). Unfortunately, much of this research employs exploratory analyses, an approach that can lead to theoretical ambiguity and ad-hoc interpretations. The current availability and accessibility of analytical tools, like structural equation modeling (SEM), however, permits the testing of specific hypotheses regarding ecological validity and promotes a-priori theory development. In the current study, a theory-driven model of the ecological validity of a neurocognitive assessment was tested against data obtained from individuals with acquired brain injury using SEM. The results provide confirmatory evidence for the ecological validity of neurocognitive constructs and empirical support for a theory-driven analytical approach to ecological validity research.  相似文献

This paper describes an adaptation of behavioral activation (BA) for the early intervention of posttraumatic stress disorder (PTSD) and depression among physically injured survivors of traumatic injury, and presents pilot data on a small randomized effectiveness trial (N = 8). The application of BA to PTSD is based on the theory that increases in guided activity may break patterns of avoidance that can maintain PTSD. Compared to treatment as usual (TAU), those who received BA showed improvement in PTSD symptom severity from pre- to posttreatment, and there was a trend for the BA group to score better than the TAU group on physical functioning. Contrary to expectation, this brief adaptation did not have an impact on depression. Implications of these results for the effective early intervention after trauma are discussed.  相似文献

Although home Internet access has continued to increase, little is known about actual usage patterns in homes. This nationally representative study of over 4,700 Italian households with children measured computer and Internet use of each family member across 3 months. Data on actual computer and Internet usage were collected by Nielsen//NetRatings service and provide national baseline information on several variables for several age groups separately, including children, adolescents, and adult men and women. National averages are shown for the average amount of time spent using computers and on the Web, the percentage of each age group online, and the types of Web sites viewed. Overall, about one-third of children ages 2 to 11, three-fourths of adolescents and adult women, and over four-fifths of adult men access the Internet each month. Children spend an average of 22 hours/month on the computer, with a jump to 87 hours/month for adolescents. Adult women spend less time (about 60 hours/month), and adult men spend more (over 100). The types of Web sites visited are reported, including the top five for each age group. In general, search engines and Web portals are the top sites visited, regardless of age group. These data provide a baseline for comparisons across time and cultures.  相似文献

OBJECTIVES: Autonomy support is a component of the motivational climate in youth sport that may promote youth's internalization of behaviors and attitudes. This study examined the psychometric properties of the Autonomy-Supportive Coaching Questionnaire (ASCQ), a measure of two forms of autonomy-supportive coaching perceived by young athletes. DESIGN: The study design was non-experimental. METHODS: Over a six-week season, youth (N = 165) participating in a recreational summer swim league completed measures of perceived coaching behavior (weeks 1 and 5), autonomy-supportive coaching (week 5) and psychological need satisfaction (weeks 1 and 6). RESULTS: Responses to the ASCQ could be reduced to two correlated factors representing an "interest in athlete's input" and "praise for autonomous behavior." These factors exhibited slightly different relations with perceived coaching behaviors and positively predicted coaching-associated contrasts in the satisfaction of all three basic psychological needs. CONCLUSIONS: The ASCQ appears to provide a valid assessment of young athlete's perceptions of autonomy-supportive coaching. Autonomy-supportive coaching should be evaluated as a potential source of motivational consequences of coaching and as a potential moderator of coaching effects on youth internalization.  相似文献

With increasing numbers of older drivers on Australian roads, it is important to determine the functional abilities most closely related to driving ability among older adults. To this end, 90 drivers aged from 60 to 91 completed a battery of psychological, visual, physical and cognitive tests, and a standardised on-road driving test. A computerised test of visual attention, devised specifically for the study, was the best predictor of on-road driving performance. Other abilities that made independent contributions to the prediction of driving performance were contrast sensitivity and visuospatial memory. These functional abilities provided a better prediction of driving performance than chronological age, reinforcing the argument that drivers should only have their driving tested when their functional abilities decline, rather than when they reach a particular age.  相似文献

The role of worry in generalized anxiety disorder (GAD) has been posited to serve as an avoidance of emotional experience, and emotion regulation deficits in GAD have been found in several previous studies. It remains unclear whether those with GAD experience more dysregulated emotions during periods of euthymia and positive affect or whether these deficits occur only during periods of worry. Individuals with GAD (with and without co-occurring dysphoria) and non-anxious controls were randomly assigned to receive a worry, neutral, or relaxation induction. Following the induction, all participants viewed a film clip documented to elicit sadness. Intensity of emotions and emotion regulation were examined following the induction period and film clip. The results revealed that, regardless of co-occurring dysphoria, individuals with GAD in the worry condition experienced more intense depressed affect than GAD participants in the other conditions and controls participants. In contrast, presence of worry appeared to have less impact on indices of emotion dysregulation, which were greater in participants with GAD compared to controls, but largely insensitive to contextual effects of worry or of relaxation. Following film viewing, both GAD participants with and without dysphoria displayed poorer understanding, acceptance, and management of emotions than did controls. However, acceptance and management deficits were most pronounced in individuals with both GAD and co-occurring dysphoria. Implications for the role of emotions in conceptualization and treatment of GAD are discussed.  相似文献

This study examined how social reality restricts children's tendency for in-group favoritism in group evaluations. Children were faced with social reality considerations and with group identity concerns. Using short stories, in this experimental study, conducted among 3 age groups (6-, 8-, and 10-year-olds), the authors examined the trait attribution effects of reality constraints on eye-color differences and national group differences. The results show that the trait attributions of all age groups were restricted by the acceptance of socially defined reality. In addition, when the information about reality was not considered accurate, only the youngest children showed positive in-group favoritism. It is argued that these findings are useful in trying to reconcile some of the divergent and contrasting findings in the developmental literature on children's intergroup perceptions and evaluations.  相似文献
