An internet survey of emotional health,treatment seeking and barriers to accessing mental health treatment among Chinese-speaking international students in Australia

The present internet survey examined the demographic characteristics of Chinese-speaking international students in Australia, psychological distress levels as measured by the Kessler-10 (K-10) Item scale, help-seeking history and preferences, as well as treatment barriers. Of the 144 respondents, 54% reported high psychological distress (mean K-10 score?=?23.96; SD?=?9.03). However, only 9% of those who were highly distressed reported they had sought mental health services in the past year. While the majority preferred help from informal social networks, they tended to favour mental health services over traditional culture-specific forms of help. Common barriers to accessing mental health services reported by respondents with high psychological distress included costs or transportation concerns, limited knowledge of available services, time constraints, the perception that symptoms were not severe enough to warrant treatment, language difficulties and lack of knowledge of symptoms of psychological distress. Although the majority preferred face-to-face treatments over internet treatments, a considerable percentage of respondents were willing to try either treatment modality. Chinese-speaking international students are a high risk group for developing psychological distress, yet they tend to underuse mental health services. Education about the effectiveness of face-to-face and online treatments may increase treatment seeking by this population.     

Ethics,Changing Populations,and the Dental Profession

This review emphasizes the worldwide and U.S. evolving population demographics and the need for the dental profession to exercise its professional and ethical duty to expand its traditional patient base to provide needed services.     

Task-irrelevant visual motion and flicker attenuate the attentional blink

Our reduced ability to correctly report two sequentially presented targets is seen in the robust effect known as the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992). One recent report (Olivers & Nieuwenhuis, 2005) strikingly reveals the AB to be virtually abolished when non-task-demanding music occurs in the background. The authors suggest that a diffuse attentional state is the mediating factor. Here, we seek to broaden the finding’s generality by determining if task-irrelevant visual motion and flicker also attenuate the AB. In our experiments, the AB task was presented together with a background field of moving dots that could moveaway from ortoward the central AB task, or flicker. In the control condition, the dots remained static. The AB was attenuated—though to different degrees—in all experimental conditions, but not in the static condition. Our findings add to the generality of the previous conclusions, and we emphasize an account based on the overallocation of attention.
