The present study examined the nature of social support exchanged within an online HIV/AIDS support group. Content analysis was conducted with reference to five types of social support (information support, tangible assistance, esteem support, network support, and emotional support) on 85 threads (1,138 messages). Our analysis revealed that many of the messages offered informational and emotional support, followed by esteem support and network support, with tangible assistance the least frequently offered. Results suggest that this online support group is a popular forum through which individuals living with HIV/AIDS can offer social support. Our findings have implications for health care professionals who support individuals living with HIV/AIDS.

This study compares public stigma towards three types of infectious diseases- human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), severe acute respiratory syndrome (SARS), and tuberculosis (TB)-tests an attribution model of stigma, and explores the relationships between stigma and public attitudes towards government policies in Hong Kong. Using a population-based telephone survey, 3011 Hong Kong Chinese adults were randomly assigned to one of the three disease conditions and were interviewed about their attitudes and beliefs towards the assigned disease. Findings showed that public stigma was the highest towards HIV/AIDS, followed by TB and SARS. Using multi-sample model structural equation modeling, we found that the attributions of controllability, personal responsibility, and blame were applicable in explaining stigma across three disease types. Knowledge about the disease had no significant effect on stigma. Participants with less stigmatizing views had significantly more favorable attitudes towards government policies related to the diseases. The study is an important attempt in understanding the attributional mechanisms of stigma towards infectious diseases. Implications for stigma reduction and promotion of public awareness and disease prevention are discussed.

Physical exercise programmes obtain clinically relevant outcomes in the treatment of depressive symptoms in depressed older people. Exercise, though not appropriate for all in this population, may improve mood in this group. Further research is needed to establish medium- to long-term effects and cost-effectiveness.

This study indicates that the health profile of pre-registration nurses is relatively poor, and that those who are sedentary engage in other negative lifestyle behaviours also. Despite significant education relating to health promotion and health behaviours of patients being targeted at pre-registered nurses, it seems that this knowledge is not always transferred to their own behaviour. There is a need for timely intervention to establish healthy lifestyle behaviours amongst nurses early in their career.

We developed an innovative home-based HIV self-testing (HIVST) service that included mailing of a free HIVST kit, and providing online real-time instructions and pre-test/post-test counseling (HIVST-OIC). The present parallel-group and non-blinded randomized controlled trial was conducted to evaluate the efficacy of promoting HIVST-OIC in increasing HIV testing rate among 430 men who have sex with men (MSM), with access to online live-chat applications in Hong Kong. At month 6, as compared to the control group, the intervention group reported significantly higher prevalence of HIV testing of any type (89.8 vs. 50.7%; relative risk (RR): 1.77; p < 0.001). Among those who have taken up any HIV testing in the last six months, significant between-group difference was found in multiple male sex partnerships (34.2 vs. 47.7%, RR: 0.72; p = 0.021). HIVST-OIC has a strong potential in increasing prevalence of HIV testing and reducing sexual risk behaviors. Implementation research is warranted.

The underutilization of professional care is a perennial problem among Chinese populations. To examine the social-cognitive factors that may affect help-seeking intentions, the present study applied and extended Ajzen's theory of planned behavior (TPB) to understand the intention to seek help from mental health professionals among Chinese. The effect of mental health and perceived barriers to help-seeking were also examined. Nine hundred and forty-one Chinese were recruited using a randomized household design in Hong Kong. Results from structural equation modeling showed that attitude, subjective norm, perceived behavioral control, and perceived barriers significantly predicted help-seeking intention. Mental health showed no significant effect on help-seeking intention. In addition, subjective norm indirectly predicted intention to seek help from mental health professionals through influencing attitude and perceived behavioral control. Results from multi-group analyses revealed that all path coefficients were invariant across gender. Results supported the utilization of TPB in understanding help-seeking intentions and highlighted the importance of subjective norm among Chinese. Implications on the enhancement of mental health awareness and the promotion of mental health services through a social-cognitive approach were highlighted.
