Researchers have long debated whether adopted youth manifest disproportionate levels of psychological dysfunction compared with non‐adopted youth. Yet, missing from the debate has been a clear understanding of the specific subgroups of adopted youth who may develop behaviour problems and of the risk factors associated with various vulnerable populations. This longitudinal study examined one subpopulation of adopted youth – former foster children – in order to determine their immediate and long‐term functioning, particularly in comparison with their adopted non‐foster care peers. The central goal of this study was to ascertain the prevalence of behavioural problems in adopted foster youth compared with adopted non‐foster youth and to chart the longitudinal course of their behavioural problems. Participants included adopted foster youth (n = 293) and adopted non‐foster youth (n = 312) from a statewide sample of adopted youth, aged 2–18 years. Data were collected from the adoptive parents at approximately 2, 4 and 8 years after adoption. Adoptive parents rated youths’ functioning with the Behaviour Problems Inventory. According to parental report, a striking number of the foster youth displayed behaviour problems, although the non‐foster care group of children also displayed noteworthy levels of problem behaviours. The rates of behaviour problems in both groups far exceed what is observed in the general population of children. 相似文献

Young lesbian, gay, bisexual, and transgender (LGBT) people labeled with intellectual disabilities have unique sexual health needs that are not being met. Denial by others of their right to pleasure and the exercise of heightened external control over their sexuality are commonplace. Current research indicates that these youth are at heightened risk for compromised sexual health. This study aimed to explore the ways in which social and environmental conditions influence vulnerability to adverse sexual health outcomes for this population. We used a community-based research approach to conduct qualitative interviews and focus groups with 10 young LGBT people (aged 17-26) labeled with intellectual disabilities. Participants reported multiple limitations on their autonomy that resulted in having sex in places where they did not feel comfortable and were unlikely to practice safer sex. Attempts by authority figures to protect youth through limits on their autonomy may be unintentionally leading to negative sexual health outcomes. 相似文献

This study was designed to empirically examine the effects of iPod device and text-messaging activities on driver distraction. Sixty participants were asked to perform a driving simulation task while searching for songs using an iPod device or text messaging. Driving errors as measured by lane deviations were recorded and analyzed as a function of the distracters. Physiological measures (EEG) were also recorded during the driving phases in order to measure participant levels of cortical arousal. It was hypothesized that iPod use and text messaging would result in a profound effect on driving ability. The results showed a significant effect of iPod use and text-messaging on driving performance. Increased numbers of driving errors were recorded during the iPod and text-messaging phases than the pre- and post-allocation phases. Higher levels of Theta activity were also observed during the iPod and Text-messaging phase than the pre- and post-allocation phases. Implications for in-vehicle systems design, training, and safety are also discussed. 相似文献

This poster presents a study to assess one's ability to detect motorcycles under different conditions of conspicuity while performing a secondary visual load task. Previous research in which participants were required to detect motorcycles revealed differences in age (young adults/older adult) as well as differences associated with motorcycle conspicuity conditions. Past research has specifically found motorcycles with headlights ON and modulating headlights (flashing) to be more conspicuous than motorcycles with headlights OFF within traffic conditions. The present study seeks to provide more information on the effects of multitasking on motorcycle conspicuity and safety. The current study seeks to determine the degree to which multitasking limits the conspicuity of a motorcycle within traffic. We expect our results will indicate main effects for distraction task, age, gender, motorcycle lighting conditions, and vehicular DRLs on one's ability to effectively detect a motorcycle. The results have implications for motorcycle safety in general and through this research, a better understanding of motorcycle conspicuity can be established so as to minimize the risk involved with motorcycle operation. 相似文献

Heaping is often found in discrete quantitative data based on subject responses to open-ended interview questions or observer assessments. Heaping occurs when subjects or observers prefer some set of numbers as responses (e.g. multiples of 5) simply because of the features of this set. Although heaping represents a common type of measurement error, apparently no prior general measure of heaping exists. We present simple measures and tests of heaping in discrete quantitative data, illustrate them with data from an epidemiologic study, and evaluate the bias of these statistics. These techniques permit formal measurement of heaping and facilitate comparisons of the degree of heaping in data from different samples, substantive domains, and data collection methods. 相似文献

Distracted driving has been shown to be a safety issue in numerous studies. To combat this problem, in-vehicle technology, legislation, media interventions, and other methods have been proposed and attempted. However research indicates that the drivers themselves may circumvent, ignore, or not be able to react in time for these interventions to be effective. Therefore research into training programs for drivers may improve reaction time under distraction. Research indicates that action game players have faster reaction times and more attentional resources than non-players on paper-based tests. However, transferability to driving has not been studied yet. This paper outlines a study to determine if action game players perform better at a driving task based on frequency of game-play. Participants will be placed into two groups of play (high vs. low) and tested against two levels of distraction (none vs. phone conversation). It is expected that participants who play higher frequency of action games will perform better under distraction than lower frequency players. Driver performance, conversation recall, frequency and durations of eye fixations will be analyzed based on previous research which has validated those variables as a measure of distraction and higher workload. 相似文献

Abstract Collegiate American football players may be at risk for cardiovascular disease. Objective: To compare cardiovascular disease risk factors and cardiovascular structure and function parameters of football players, stratified by position, to a group of sedentary, nonathletes. Participants: Twenty-six collegiate football players and 13 nonathletes participated in this study. Methods: Blood pressures, anthropometrics, and blood chemistries were obtained and analyzed using standardized procedures. Resting echocardiography was used to evaluate cardiac morphology and function. Brachial artery flow-mediated dilation was assessed using high-resolution ultrasonography. Results: The prevalence of the metabolic syndrome was significantly higher amongst the linemen compared to the skill-position players (46% versus 0%, p < .05). Mildly abnormal wall thickness was noted in 20% of the football players. No significant differences in vascular function were observed between the groups. Conclusions: The increased prevalence of the metabolic syndrome and its components in the collegiate linemen may increase cardiovascular disease risk. 相似文献
