A sample of 199 persons with spinal cord injury (SCI) were assessed on Big Five personality dimensions using the NEO Five-Factor Inventory (NEO-FFI; Costa & McCrae, 1992) at admission to an inpatient medical rehabilitation program. A cluster analysis of the baseline NEO-FFI yielded 3 cluster prototypes that resemble resilient, undercontrolled, and overcontrolled prototypes identified in many previous studies of children and adult community samples. Compared with normative samples, this sample had significantly fewer resilient prototypes and significantly more overcontrolled and undercontrolled prototypes. Undercontrolled individuals were the modal prototype. The resilient and undercontrolled types were better adjusted than the overcontrolled types, showing lower levels of depression at admission and higher acceptance of disability at discharge. The resilient type at admission predicted the most effective reports of social problem-solving abilities at discharge and the overcontrolled type the least. We discuss the implications of these results for assessment and interventions in rehabilitation settings. 相似文献

The working memory (WM) construct is conceptualized similarly across domains of psychology, yet the methods used to measure WM function vary widely. The present study examined the relationship between WM measures used in the laboratory and those used in applied settings. A large sample of undergraduates completed three laboratory-based WM measures (operation span, listening span, and n-back), as well as the WM subtests from the Wechsler Adult Intelligence Scale-III and the Wechsler Memory Scale-III. Performance on all of the WM subtests of the clinical batteries shared positive correlations with the lab measures; however, the Arithmetic and Spatial Span subtests shared lower correlations than the other WM tests. Factor analyses revealed that a factor comprising scores from the three lab WM measures and the clinical subtest, Letter-Number Sequencing (LNS), provided the best measurement of WM. Additionally, a latent variable approach was taken using fluid intelligence as a criterion construct to further discriminate between the WM tests. The results revealed that the lab measures, along with the LNS task, were the best predictors of fluid abilities. 相似文献

Computer-simulated microworlds can provide a controlled method for investigating concepts related to naturalistic decision making (NDM). However, the extent to which these tools can be used to generate meaningful outcomes is unknown. The current study used a microworld called Networked Fire Chief (NFC) to explore the range of skills and knowledge acquired as participants gained practice on the program. The complexity of the NFC NDM environment was also explored. Twenty participants each completed 20 equivalent 5-min scenarios on NFC. Interview data, behavioral data and performance scores were collected across the trials. Results confirmed that NFC provides an environment that promotes appropriate perceptual-cognitive processing for NDM. However, performance improved to only a small extent across the 20 trials in four performance areas: speed, accuracy, efficiency and planning. In addition, the number of personal and situational factors to be considered when decision making on NFC was not comparable with real-world NDM environments. Overall, results indicated that the use of microworlds for research should be regulated by an understanding of the limitations of their applicability. 相似文献

OBJECTIVE: Examined the influence of mutual communal behaviors on the adjustment reported by persons with spinal cord injury (SCI) and their family caregivers. Previous research has found that persons who have a history of mutually communal behaviors in relationships may react differently to relationship changes after an acquired physical disability than dyads with few communal behaviors. METHOD: Family caregivers and persons with SCI were administered measures of mutual communal behaviors, depression, and life satisfaction. Structural equation modeling was used to test the relations among caregivers' communal behaviors and care recipients' communal behaviors, depression, and life satisfaction. RESULTS: Caregiver and care recipient reports of communal behaviors were not significantly correlated. Significant paths indicated that care recipients' communal behavior scores were positively associated with their life satisfaction, and care recipients' depression was inversely associated with their life satisfaction. Caregivers' communal behavior scores were unrelated to their self-reported adjustment. CONCLUSIONS: Caregiver-care recipient dyads may differ in their perceptions of communal behaviors in their relationships. Although care recipient reports of communal behavior may be related to their life satisfaction, communal behaviors may not serve a similar function among caregivers of persons with SCI. 相似文献

In a number of studies, we have demonstrated that the spatial-temporal coupling of eye and hand movements is optimal for the pickup of visual information about the position of the hand and the target late in the hand's trajectory. Several experiments designed to examine temporal coupling have shown that the eyes arrive at the target area concurrently with the hand achieving peak acceleration. Between the time the hand reached peak velocity and the end of the movement, increased variability in the position of the shoulder and the elbow was accompanied by a decreased spatial variability in the hand. Presumably, this reduction in variability was due to the use of retinal and extra-retinal information about the relative positions of the eye, hand and target. However, the hand does not appear to be a slave to the eye. For example, we have been able to decouple eye movements and hand movements using Müller-Lyer configurations as targets. Predictable bias, found in primary and corrective saccadic eye movements, was not found for hand movements, if on-line visual information about the target was available during aiming. That is, the hand remained accurate even when the eye had a tendency to undershoot or overshoot the target position. However, biases of the hand were evident, at least in the initial portion of an aiming movement, when vision of the target was removed and vision of the hand remained. These findings accent the versatility of human motor control and have implications for current models of visual processing and limb control. 相似文献

Fatal and nonfatal intentional self‐harm events in eight U.S. states were compared using emergency department, hospital, and vital statistics data. Nonfatal event rates increased by an estimated 24.20% over 6 years. Case fatality ratios varied widely, but two northeastern states' total event rates (fatal plus nonfatal) were very high (New Hampshire 206.5/100,000 person years; Massachusetts 166.7/100,000). Geographic context did not uniformly impact the likelihood of self‐harm across event types. The state‐level public health burden posed by such acts cannot, therefore, be accurately estimated from either mortality or morbidity data alone. 相似文献

This article addresses common dilemmas faced by mental health professionals working on behalf of law enforcement agencies, focusing on those relating to informed consent; conflicts in values, norms, or their relative importance; and the erosion of professional identity. The authors suggest 10 strategies that mental health professionals may invoke to reduce their risk of confronting ethical dilemmas or of experiencing role conflicts while working on behalf of law enforcement agencies. The need for each strategy is illustrated with one or more examples of problems that have arisen when mental health professionals have failed to obtain consent for their activities, have been insufficiently sensitive to or unaware of conflicts between the usual norms in their professions, and the norms of law enforcement agencies, or have identified too strongly with law enforcement personnel. The 10 strategies recommended here are intended to reduce professional conflicts without compromising operational effectiveness. 相似文献

The effects of self-appraisal problem-solving ability and oral contraceptive use on ratings of menstrual pain were studied among 130 undergraduate women. Participants completed the Problem-Solving Inventory (Heppner, 1988) and the Menstrual Distress Questionnaire (Moos, 1984). Regression analyses indicated that oral contraceptives–which are often prescribed to relieve menstrual pain among college women–were not predictive of lower pain ratings. Problem-solving appraisal, however, was significantly predictive of pain. Ratings of effective personal control during problem solving were associated with lower ratings of premenstrual and menstrual pain. Results are discussed as they pertain to the study of psychological factors in menstruation, and to the study of problem solving and behavioral health. 相似文献
