This paper presents a revised version of DSM-IV-J criteria for youth, the DSM-IV-MR-J, together with psychometric data stemming from its use in a major prevalence study of adolescent gambling and problem gambling. The case is made for further development and testing of current and emerging instruments to screen for problem gambling in youth, with the aim of establishing one internationally accepted gold standard measure.  相似文献

This study is the first attempt to measure the prevalence of problem gambling attributable to a specific sector of the gambling industry. One thousand, one hundred and five casino patrons in 40 casinos in the UK were interviewed, face-to-face. Respondents were screened for problem gambling using a multiple response version of DSM-IV (DSM-IV-MR). The study found support for Eadington's (1988) hypothesis, that UK casinos could be largely sustained by regular players, among whom the prevalence of problem gambling is high. The study also found support for the hypothesis that, to the extent different gambling sectors are patronised by demographically different client groups, so the problem gamblers associated with them will reflect these client groups. The problem gamblers among the regular casino patrons were demographically distinct from the problem gamblers in the sample who showed a preference for other gambling forms. Other key findings support those found in other jurisdictions. Sector-specific prevalence studies may be the next step forward in epidemiological research on problem gambling. They have the major advantage of netting significantly more problem gamblers from much smaller samples than similar studies in the general population. They also have the potential to reveal the proportion of problem gamblers attributable to each sector, along with their demographic characteristics. Such information would result in more specific information being available for regulators seeking to minimise the social impact of problem gambling and those involved in the development of prevention and treatment strategies.  相似文献

Employee health and productivity losses as a result of work-related injury are estimated to be US dollars 1.2 trillion annually to US companies. This is approximately 14.3% of the gross domestic product [6,8,11,35]. Workers' compensation, medical care, and short and long-term disability are a part of these costs. Controlling or eliminating these costs is a problem for US employers [3,6,14,21,29]. The study discussed in this article examined the perceptions of manufacturing employees in identifying factors that influence a return to work after a work-related musculoskeletal injury. The classification of employees who participated in this study were safety professionals, supervisors and workers from the manufacturing industry in central Kentucky. The worker group consisted of material handlers, assembly line workers and quality control inspectors. The participants completed a developed survey instrument, the Return to Work Perception Survey. This survey instrument examined the perception of the participants on factors related to return to work: company policies and procedures, job satisfaction, worker relationships and work environment. The results indicated safety professionals and supervisors perceptions differ from workers on the variables of job satisfaction, worker relationships and work environment. Their perceptions did not differ on the variable relating to company policies and procedures. In addition, the safety professional and supervisor groups rated the items addressing job satisfaction higher than did the worker group. The worker group did not differ from one another on any of the factors. Implications of this study for manufacturing companies suggest (a). identifying those issues contributing to employee job satisfaction, (b). developing a plan for achieving increased job satisfaction and employee recognition at the workplace among all workers, and (c). consider allowing employees to develop new capacities and new learning, thus fostering motivation and job satisfaction [18,20].  相似文献

Data from 72 infants, tested using a serial paired‐comparison paradigm, were analyzed to better understand infant novelty preferences. Infants between the ages of 15 and 26 weeks were tested in three studies with familiar stimuli displayed adjacent to novel stimuli on each trial. Differences in look duration, look number, and gaze shifts directed at novel versus familiar stimuli were assessed to measure their contributions to group and individual novelty preferences. Infants produced longer looks for novel stimuli in all three studies, and stimulus differences in look duration accounted for more than 50% of the variability in individual novelty preferences. Infants that produced more looks to novel rather than familiar stimuli did not produce overall novelty preferences unless they also looked longer at novel stimuli. Gaze shift patterns did not predict individual novelty preferences, and novel stimuli did not determine where infants looked. The infants’ visual exploration was constrained by memories for the direction of the previous look as well as by the attention‐holding features of novel stimuli.  相似文献

We investigated language development, relational aggression, and relational victimization in ethnically, socioeconomically diverse preschoolers. Relational aggression was positively related to language development. Girls were more relationally aggressive than boys, and higher‐socioeconomic status (SES) children were more relationally aggressive and victimized than lower‐SES children. Neither gender nor SES conclusively moderated the relation between language and relational aggression, though some findings suggest the possibility of stronger relations among boys and lower‐SES children. Teachers agreed on ratings of relational aggression and relational victimization to a moderate extent.  相似文献

A within-subject ABAB reversal design was utilized to investigate the effects of graphic feedback and goal setting on employee closing task completion. Goal setting was contingent upon baseline performance and graphic feedback was posted weekly. It was found that goal setting and graphic feedback improved employee closing task completion.  相似文献
