A random digit dialing telephone survey was used to interview 8,467 adults in Ontario, Canada. The NODS-CLiP was used to identify
a representative sample of 730 gamblers (54.3% male, mean age 45.3 years) with possible past year gambling problems in order
to explore factors that might affect disordered gamblers’ motivators for seeking gambling-related help. A final sample of
526 gamblers provided useable data on possible reasons for and barriers to seeking help, awareness of services, self-perception
of gambling problems and experience with help-seeking. Financial and relationship issues were the most frequently volunteered
motivators. However, over two-thirds of the respondents could not think of a reason for seeking help. Gamblers who had self-admitted
or more severe problems, who knew how to get help, who were employed and had more education, and who identified possible barriers
to seeking help were more likely to suggest motivators, especially financial ones. More research is recommended on gamblers’
trajectory towards recognition of a gambling problem, the process of overcoming specific barriers to treatment, and the role
of social advantage (e.g., education and employment), in order to devise educational campaigns that will encourage earlier
help-seeking among disordered gamblers. 相似文献

Self-forgiveness is generally understood to be a mechanism that restores and improves the self. In the current study, we examine the possible deleterious consequences of forgiving the self among gamblers-specifically in regard to gamblers' readiness to change their problematic behavior. At a large Canadian university, 110 young adult gamblers' level of gambling pathology was assessed, along with their readiness to change and self-forgiveness for their gambling. Participants were 33 females and 75 males (2 unspecified) with a mean age of 20.33. Results revealed that level of pathology (at risk vs. problem gamblers) significantly predicted increased readiness to change. Self-forgiveness mediated this relationship, such that level of gambling pathology increased readiness to change to the extent that participants were relatively unforgiving of their gambling. Implications for seeking professional assistance as well as treatment and recovery are discussed. 相似文献

Condom Use Trajectories in Adolescence and the Transition to Adulthood: The Role of Mother and Father Support 总被引:1,自引:0,他引:1
Pingel ES Bauermeister JA Elkington KS Fergus S Caldwell CH Zimmerman MA 《Journal of research on adolescence》2012,22(2):350-366
Few studies have investigated how mother and father support differ on predicting youths' sexual risk behavior. We therefore examined the influence of parental support on condom use trajectories and its correlates in a predominantly African American sample [(N=627; 53% female; M = 14.86 years (SD=. 64)] from adolescence to young adulthood. We used hierarchical growth curve modeling to examine the relationship between condom use, substance use, psychological distress and parental support prospectively. We found that consistent condom use decreased over time and was associated negatively with psychological distress and substance use. Furthermore, both maternal and paternal support were associated with more condom use over time. We discuss the implications of our findings for HIV prevention programs. 相似文献

This paper presents a multivariate method to assess the comprehension of safety signs. The proposed method uses the MDS and Procrustes, to obtain a consensus perceptual map. The results show that the map allowed discriminating signs with high levels of comprehension from others. The safety signs have no statistical difference as depicted by Bootstrap Analysis. 相似文献

Decision-making plays an important role in life-critical systems. It entails cognitive functions such as monitoring, as well as fault prevention and recovery. Three kinds of objectives are typically considered: safety, efficiency and comfort. People involved in the control and management of such systems provide two kinds of contributions: positive with their unique involvement and capacity to deal with the unexpected; and negative with their ability to make errors. In the negative view, people are the problem and need to be supervised by regulatory systems in the form of operational constraints or by design. In the positive view, people are the solution and lead the game; they are decision-makers. The former view also deals with error resistance, and the latter with error tolerance, which, for example, enables cooperation between people and decision support systems (DSS). In the real life, both views should be considered with respect to appropriate situational factors, such as time constraints and very dangerous environments. This is known as function allocation between people and systems. This paper presents a possibility to reconcile both approaches into a joint human-machine organization, where the main dimensioning factors are safety and complexity. A framework for cooperative and fault tolerant systems is proposed, and illustrated by an example in Air Traffic Control. 相似文献
