Two Web-Based and Theory-Based Interventions With and Without Brief Motivational Interviewing in the Promotion of Human Papillomavirus Vaccination Among Chinese Men Who Have Sex With Men: Randomized Controlled Trial. J Med Internet Res 2021; 23:e21465. [PMID: 33528372 PMCID: PMC7886619 DOI: 10.2196/21465] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 11/30/2020] [Accepted: 12/24/2020] [Indexed: 01/09/2023] Open
Abstract
Background Human papillomavirus (HPV) vaccination is effective in the prevention of vaccine-type genital warts and cancers among men who have sex with men (MSM). Objective The primary objective of this randomized controlled trial (RCT) is to evaluate the efficacies of 2 web- and theory–based interventions with and without brief motivational interviewing (MI) over the phone to increase the completion of HPV vaccination among unvaccinated participants within a 24-month follow-up period compared with the control group. Methods A 3-arm parallel-group RCT was conducted between July 2017 and December 2019. Five telephone surveys were conducted at baseline and at 3, 6, 9, and 24 months by blinded interviewers. Participants were Hong Kong Chinese–speaking MSM aged between 18 and 45 years with regular internet access who were recruited from outreaching at venues, web-based recruitment, and peer referral. Those who had ever received HPV vaccination were excluded. A total of 624 participants were randomized into either the online tutorial (OT) only group (n=208), the OT plus MI group (OT-MI; n=208), or the control group (n=208). In total, 459 (459/624, 73.6%) completed the follow-up evaluation at 24 months. Participants in the OT group received a fully automated OT developed based on the health belief model. On top of the same OT, the OT-MI group received brief MI over the phone. Reminders were sent to the participants of the OT and OT-MI groups after 1, 2, 4, 6, and 8 months. Participants in the control group received web-based health communication messages unrelated to HPV or HPV vaccination. The research team validated the self-reported HPV vaccination uptake. Intention-to-treat analysis was used for outcome analyses. Logistic regression models and multivariable linear regression models were used to test the between-group differences in primary and secondary outcomes. Baron and Kenny’s methods were used to test the mediation hypothesis. Results The participants in the OT-MI group reported a significantly higher validated completion of HPV vaccination at 24 months than the control group (36/208, 17.3% vs 15/208, 7.2%; P=.006). However, the difference in HPV vaccination completion between the OT and the control groups (24/208, 11.5% vs 15/208, 7.2%; P=.17), or between OT-MI and OT groups (P=.13), was not statistically significant. The association between randomization status (OT-MI group vs control group) and HPV vaccination completion became statistically nonsignificant after controlling for changes in the perceived susceptibility to HPV (24 months vs baseline), whereas perceived susceptibility remained strongly associated with HPV vaccination uptake in the model (P<.001). Changes in perceived susceptibility fully mediated the intervention effect. Conclusions Theory-based OT with brief MI over the phone was effective in increasing HPV vaccination completion among Chinese MSM. Perceived susceptibility is an active theoretical component that causes behavioral changes. Trial Registration ClinicalTrials.gov NCT03286907; https://clinicaltrials.gov/ct2/show/NCT03286907

Social, Cognitive, and eHealth Mechanisms of COVID-19-Related Lockdown and Mandatory Quarantine That Potentially Affect the Mental Health of Pregnant Women in China: Cross-Sectional Survey Study. J Med Internet Res 2021; 23:e24495. [PMID: 33302251 PMCID: PMC7836909 DOI: 10.2196/24495] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 11/01/2020] [Accepted: 11/30/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Although lockdown and mandatory quarantine measures have played crucial roles in the sharp decrease of the number of newly confirmed/suspected COVID-19 cases, concerns have been raised over the threat that these measures pose to mental health, especially the mental health of vulnerable groups, including pregnant women. Few empirical studies have assessed whether and how these control measures may affect mental health, and no study has investigated the prevalence and impacts of the use of eHealth resources among pregnant women during the COVID-19 outbreak. OBJECTIVE This study investigated (1) the effects of lockdown and mandatory quarantine on mental health problems (ie, anxiety and depressive symptoms), (2) the potential mediation effects of perceived social support and maladaptive cognition, and (3) the moderation effects of eHealth-related factors (ie, using social media to obtain health information and using prenatal care services during the COVID-19 pandemic) on pregnant women in China. METHODS An online cross-sectional survey was conducted among 19,515 pregnant women from all 34 Chinese provincial-level administrative regions from February 25 to March 10, 2020. RESULTS Of the 19,515 participants, 12,209 (62.6%) were subjected to lockdown in their areas of residence, 737 (3.8%) were subjected to mandatory quarantine, 8712 (44.6%) had probable mild to severe depression, 5696 (29.2%) had probable mild to severe anxiety, and 1442 (7.4%) had suicidal ideations. Only 640 (3.3%) participants reported that they used online prenatal care services during the outbreak. Significant sociodemographic/maternal factors of anxiety/depressive symptoms included age, education, occupation, the area of residence, gestational duration, the number of children born, complication during pregnancy, the means of using prenatal care services, and social media use for obtaining health information. Multiple indicators multiple causes modeling (χ214=495.21; P<.05; comparative fit index=.99; nonnormed fit index=.98; root mean square error of approximation=.04, 90% CI 0.038-0.045) showed that quarantine was directly and indirectly strongly associated with poor mental health through decreased perceived social support and increased maladaptive cognition (B=.04; β=.02, 95% CI 0.01-0.02; P=.001), while lockdown was indirectly associated with mental health through increased social support and maladaptive cognition among pregnant women (B=.03; β=.03, 95% CI 0.02-0.03; P=.001). Multigroup analyses revealed that the use of social media for obtaining health information and the means of using prenatal care services were significant moderators of the model paths. CONCLUSIONS Our findings provide epidemiological evidence for the importance of integrating mental health care and eHealth into the planning and implementation of control measure policies. The observed social and cognitive mechanisms and moderators in this study are modifiable, and they can inform the design of evidence-based mental health promotion among pregnant women.

Abstract
OBJECTIVE Suboptimal self-care by individuals with diabetes mellitus (DM) is a significant public health concern. The common-sense model (CSM) proposes that illness representations are associated with coping and health outcomes across various conditions. The present study examined the efficacy of a CSM-based intervention in improving illness representations, self-care, self-care self-efficacy, use of adaptive coping strategies, and glycated hemoglobin among individuals with type 2 DM (T2DM). METHODS A two-arm randomized controlled trial was used. A total of 455 T2DM patients were recruited from an outpatient DM clinic and randomized to an intervention group that consisted of five weekly group-based education sessions or a control group that received five weekly educational booklets. Evaluation was conducted at baseline and at 1- and 6-month follow-up. RESULTS The 2 × 3 linear mixed-model analysis using a modified intention to treat revealed a significant time by condition interaction effect on level of self-care (F(2,840) = 7.78, p < .001), self-care self-efficacy (F(1.89,794.57) = 14.40, p < .001), and use of adaptive coping strategies (F(1.94,812.93) = 4.75, p = .010) in which participants in the intervention group reported greater improvement in such aspects compared with those in the control group. A significant time effect was observed in some dimensions of illness representations. No significant effect was found in glycated hemoglobin. Participants reported positive feedback to the intervention and perceived improvement in various domains. CONCLUSIONS The CSM-based intervention was effective in improving self-care and coping among DM patients. The intervention also demonstrated high feasibility and acceptability. Findings provided important insights in improving health-related outcomes for patients with T2DM using the CSM framework.

Abstract
This study investigated the associations between illness representations of pneumonia and pneumococcal vaccination (PV) uptake among a group of community-living aging adults having at least one high-risk condition for severe invasive pneumococcal diseases (IPD). A total of 750 community-living Chinese-speaking individuals aged ≥65 y completed a random telephone survey. This study was based on 483 participants having at least one high-risk condition for severe IPD. The Illness Representation Questionnaire-Revised (IPQ-R) measured four dimensions of illness representations. These dimensions included timeline (whether pneumonia is believed to be acute/chronic), consequences (severity of pneumonia), treatment control (whether pneumonia is under volitional control), and emotional response (anger, guilty, or shame). Using PV uptake (among all participants) and behavioral intention to take up PV (among unvaccinated participants) as the dependent variables, logistic regression models were fitted. Among all participants (n = 483), 17.8% reported PV uptake; 18.6% of unvaccinated participants (n = 397) intended to take up two doses of free PV in the next year. After adjustment for significant background variables, participants who perceived more severe consequences of pneumonia (adjusted odds ratios, AOR: 1.18, 95%CI: 1.01, 1.40) and belief that treatment can control pneumonia (AOR: 1.41, 95%CI: 1.25, 1.58) reported higher PV uptake. Perceived pneumonia to be chronic (AOR: 1.44, 95%CI: 1.16, 1.78), belief that treatment can control pneumonia (AOR: 1.25, 95%CI: 1.12, 1.40) and having negative emotions related to pneumonia (AOR: 1.17, 95%CI: 1.09, 1.25) were positively associated with behavioral intention to take up PV. Results confirmed that illness representations were associated with PV-related behaviors.

Abstract
Background Sexualized drug use (SDU; the use of any psychoactive substance before or during sexual intercourse) is prevalent among men who have sex with men (MSM) and may aggravate the worsening HIV epidemic in this key population. Objective This observational prospective cohort study investigated factors predicting the occurrence of SDU within a 6-month follow-up period among a sample of MSM in Hong Kong. We hypothesized that perceptions related to SDU would mediate the association between the influence of social media/gay social networking apps and SDU during the follow-up period. Methods Participants were Chinese-speaking men in Hong Kong, China who had anal intercourse with at least one man in the past year. Among 600 participants who completed the baseline telephone survey, 407 (67.8%) completed another telephone survey 6 months later. Logistic regression models and path analysis were fitted. Results At Month 6, 6.9% (28/407) and 4.4% (18/407) of participants reported SDU and chemsex during the follow-up period. After adjustment for significant baseline background variables (use of pre-exposure prophylaxis; history of HIV and other sexually transmitted infections; anal intercourse with nonregular male sex partners, condomless anal intercourse with men, multiple male sex partnerships, and SDU at baseline), three constructs of the Theory of Planned Behavior (TPB) were significantly associated with SDU during the follow-up period: (1) positive attitudes toward SDU (adjusted odds ratio [AOR] 1.19, 95% CI 1.05-1.36), (2) perceived support for SDU from significant others (AOR 1.15, 95% CI 1.01-1.30), and (3) perceived behavioral control of refraining from SDU (AOR 0.76, 95% CI 0.59-0.98). Exposure to information supporting SDU on social media and gay social networking apps was also significantly associated with SDU (AOR 1.11, 95% CI 1.01-1.22). Bootstrapping analyses indicated that social media influence was indirectly associated with SDU through TPB-related perceptions of SDU (β=.04; B=.002, 95% CI 0.001-0.01). Conclusions Social media and gay social networking apps may be a major source of influence on MSM’s perceptions and actual behaviors related to SDU.

Abstract
Drug use is globally more prevalent in HIV-positive men who have sex with men (HIVMSM) than their heterosexual counterparts. Yet, few studies have investigated the factors associated with drug use among this population beyond Western societies. A cross-sectional survey was conducted to examine factors associated with drug use among 415 HIVMSM in Chengdu, China. The results show that 10.8% of the participants had used drugs in the past 30 days. Among participants who had anal intercourse in the past 30 days, 11.5% had used drugs during anal intercourse. After adjusting for background variables, logistic regression models show that life satisfaction was associated with past 30-day drug use [Adjusted Odds Ratio (ORa) = 0.90, p < 0.001], and with drug use during anal intercourse in the past 30 days (ORa = 0.89, p < 0.01). Participants with more nonregular partners were more likely to use drugs with or without sex in the past 30 days, whereas those with one regular partner were less likely to use drugs during anal intercourse compared to their counterparts with no regular partners. The findings of this study are informative for designing effective substance-use intervention programs targeting HIVMSM.

Abstract
This study aims to test the associations between interpersonal resources and posttraumatic growth (PTG) and their indirect associations through resilience among women living with HIV (WLWH). A cross-sectional study interviewed 546 WLWH from eight clinics of Yunnan and Guangxi provinces in China. PTG, resilience and doctors' empathy were assessed by the validated scales. Family support, friend support, and partner intimacy were assessed by the self-constructed scales. Significant background factors of PTG included duration of residence in the area, monthly family income, number of years since HIV diagnosis, self-reported presence of AIDS-related symptoms, and current pregnancy. Family social support, partner intimacy, doctors' empathy, and resilience were positively associated with PTG; friend support was negatively associated with PTG (p < .05). Furthermore, resilience partially mediated the relationships between family support/partner intimacy and PTG, explaining 13.6-14.2% of the variance. Structural equation modeling showed that family support was significantly and indirectly associated with PTG through resilience when controlling for other interpersonal resource indicators. Implications and potential interventions to promote PTG are discussed.

Abstract
Background Sexualized drug use (SDU) refers to use of any psychoactive substance before/during sexual intercourse. Chemsex is a subset of SDU, which is defined as the use of some specific psychoactive substances (methamphetamine, mephedrone, γ-hydroxybutyrate, ketamine and cocaine) before/during sexual intercourse. SDU and chemsex are prevalent among gay, bisexual and other men who have sex with men (GBMSM). This study investigated uptake and willingness to use pre-exposure prophylaxis (PrEP) among a sample of GBMSM in Hong Kong with experience of SDU in the past year. Methods A total of 600 GBMSM were recruited by convenient sampling through outreaching in gay venues, online recruitment and peer referral. Participants completed a cross-sectional anonymous telephone interview. This study was based on a subsample of 580 GBMSM self-reported as HIV negative/unknown sero-status. Results Of the participants, 82 (14.1%) and 37 (6.4%) had experience of SDU and chemsex in the past year. The prevalence of PrEP uptake was 4.0% among all participants and 14.6% among those with experience of SDU in the past year. Among GBMSM with experience of SDU in the past year who were not on PrEP (n = 70), 67.1% were willing to use daily oral PrEP in the next 6 months. Multivariate logistic regression models showed that positive attitudes toward PrEP (AOR: 2.37, 95%CI: 1.47, 3.82), perceived support from significant others to use PrEP (AOR: 9.67, 95%CI: 2.95, 31.71), and perceived behavioral control of using PrEP (AOR: 19.68, 95%CI: 5.44, 71.26) were significantly associated with higher willingness to use PrEP. Conclusion GBMSM with experience of recent SDU are potentially good candidates of PrEP implementation. This group of GBMSM reported high prevalence of uptake and willingness to use PrEP. Perceptions related to PrEP based on the Theory of Planned Behavior were significantly associated with willingness to use PrEP.

Abstract
OBJECTIVES Men who have sex with men (MSM) are at high risk of hepatitis C virus (HCV). This study investigated predictors of first-time HCV testing uptake during a 6-month period among a sample of MSM in Hong Kong. METHODS Participants were 351 Chinese-speaking MSM who had never received HCV testing. Participants completed two telephone surveys 6 months apart. At baseline, participants reported on sociodemographics, sexual behaviours, risk perception, depressive symptoms and anxiety symptoms. Illness representations, which refers to how people think about HCV, was measured by the Brief Illness Perception Questionnaire (BIPQ) at baseline. The BIPQ assessed identity (identifying symptoms of HCV), timeline (whether HCV is acute/chronic), consequences (severity of HCV), personal control and treatment control (whether HCV is under volitional control), concern, emotions (anger, guilt or shame) and coherence (overall comprehensibility of HCV). Six months later, participants reported on HCV testing uptake. Logistic regression was used to analyse the associations between baseline predictors and HCV testing uptake. RESULTS Most participants were aged ≤30 years (55.0%) and had attained college education or above (85.2%). Among 242 participants (68.9%) who completed the month 6 follow-up, 12.4% had tested for HCV during the follow-up period. After adjustment for HIV testing and chemsex in the last year, participants who perceived more severe consequences of HCV reported higher HCV testing uptake (adjusted ORs (AOR): 2.22, 95% CI: 1.65 to 3.00). Belief that treatment can control HCV (AOR: 1.75, 95% CI: 1.35 to 2.26) and having negative emotions related to HCV (AOR: 1.59, 95% CI: 1.25 to 2.03) were also positively associated with HCV testing uptake. CONCLUSIONS Targeted health promotion efforts are needed to increase HCV testing among MSM in Hong Kong. Healthcare workers engaged in HCV-related programming should consider modifying the illness representations of HCV. Integrating HCV and HIV testing services may also be beneficial.

Abstract
BACKGROUND Mental illness is a great concern among children of HIV-infected parents (COHIP), who are at their crucial stage of psychosocial development. It has been shown that self-concept (SC) and social support (SS) are important correlates of anxiety symptoms (AS), however, nature of the causality remained unclear. METHODS A 3-year longitudinal study was conducted in rural Central China, where many people were infected with HIV through unhygienic blood donation. A total of 195 COHIP (mean age: 12.6 years, 49.2% male) completed the baseline assessment and were followed for three years. Cross-lagged structural equation modeling analyses were used to test competing theoretical models: vulnerability model (low SC/SS contributes to AS), scar model (AS erodes SC/SS) and reciprocity model (low SC/SS and AS predict each other). RESULTS At each wave, 104 (53.3%) and 67 (41.6%) participants presented with anxiety disorders respectively. Nested-model comparison supported the superiority of scar models wherein AS significantly predicted subsequent low SC (β=-0.24, p=0.013) and SS (β=-0.31, p= 0.033), controlling for synchronous and autoregressive effects of all measures. The most parsimonious multivariate model that included significant relations was finally identified with a good model fit. LIMITATIONS Findings might be subject to reporting bias; and could not inform the temporal relationship between SC and SS. CONCLUSION Prevalence of anxiety was high among Chinese COHIP. The present study provides empirical evidence for scarring effects of AS; thus, highlighted the importance of identifying and treating COHIP's anxiety to mitigate long-term negative impacts on their psychosocial development.

Abstract
Maternal HIV disclosure to children has numerous benefits for both mothers and children. However, the prevalence of maternal HIV disclosure to children remains low in many countries. The present study examined factors associated with intention to disclose maternal HIV status to children among Chinese HIV+ women who have not disclosed their HIV status to their child. Factors from the Theory of Planned Behavior and various norms (injunctive, descriptive and moral norm) were examined. Findings from 179 HIV+ women revealed that only 16.8% intended to disclose their HIV status to their child in the future. Adjusted for significant background variables, all factors from the TPB and various norms (i.e. attitude, injunctive norm, descriptive norm, moral norm, perceived behavioural control) were associated with intention to disclose HIV status (adjusted odds ratios ranged from 3.22, 15.85). Stepwise logistic regression showed that attitude (ORm = 6.96) and injunctive norm (ORm = 6.81) were associated with intention to disclose HIV status. Interventions to promote maternal HIV disclosure were warranted to promote attitude, perceived behavioural control, and various norms associated with HIV disclosure.

Abstract
AIMS The aim of this study was to examine the prevalence and the factors associated with influenza vaccination among nurses in Hong Kong based on the Health Belief Model. The role of moral responsibility was also examined. BACKGROUND Influenza vaccination is the most effective way to prevent influenza infection. Nurses are recommended to receive influenza vaccination annually. However, the rate of vaccination among nurses in Hong Kong is low. DESIGN A cross-sectional study. METHOD A survey was conducted among 214 nurses between January - March 2017. RESULT The prevalence of having ever received influenza vaccination, having received influenza vaccination in the last influenza season and having intention to receive influenza vaccination in the coming influenza season were 64.5%, 29.0% and 23.3% respectively. Results from multiple stepwise logistic regressions showed that perceived benefits of influenza vaccination and having received recommendations from colleagues were associated with higher chances of having ever received influenza vaccination. Perceived susceptibility of influenza, perceived benefits of influenza vaccination and perceived moral responsibility were associated with higher chances of having received influenza vaccination in the last influenza season, whereas perceived barriers of influenza vaccination were associated with lower chances. Furthermore, perceived susceptibility of influenza and perceived benefits of influenza vaccination were associated with higher chances of having the intention to receive influenza vaccination in the coming influenza season, whereas perceived barriers were associated with lower chances. The moderating effect of perceived moral responsibility was not significant. CONCLUSION Health promotion should make use of the Health Belief Model and increase moral responsibility to increase influenza vaccination rate among nurses.

Abstract
This study was to investigate the prevalence and associated factors of inconsistent condom use with HIV-discordant regular male sex partners (RP: defined as their husband or steady boyfriends) in the last six months among HIV-infected women in China. We interviewed 256 HIV-infected women who currently had at least one HIV-discordant RP and had had sexual intercourse with such RP since diagnosis. The prevalence of inconsistent condom use with HIV-discordant RP was 48.4%. Associated factors included perceptions related to condom use and perceived competence in communicating with HIV-discordant RP regarding condom use.

Abstract
BACKGROUND AND AIMS The aim of the study is to investigate (a) whether probable depression status assessed at baseline prospectively predicted new incidence of Internet addiction (IA) at the 12-month follow-up and (b) whether IA status assessed at baseline prospectively predicted new incidence of probable depression at follow-up. METHODS We conducted a 12-month cohort study (n = 8,286) among Hong Kong secondary students, and derived two subsamples. The first subsample (n = 6,954) included students who were non-IA at baseline, using the Chen Internet Addiction Scale (≤63), and another included non-depressed cases at baseline (n = 3,589), using the Center for Epidemiological Studies Depression Scale (<16). RESULTS In the first subsample, 11.5% of the non-IA cases developed IA during follow-up, and probable depression status at baseline significantly predicted new incidence of IA [severe depression: adjusted odds ratio (ORa) = 2.50, 95% CI = 2.07, 3.01; moderate: ORa = 1.82, 95% CI = 1.45, 2.28; mild: ORa = 1.65, 95% CI = 1.32, 2.05; reference: non-depressed], after adjusting for sociodemographic factors. In the second subsample, 38.9% of those non-depressed participants developed probable depression during follow-up. Adjusted analysis showed that baseline IA status also significantly predicted new incidence of probable depression (ORa = 1.57, 95% CI = 1.18, 2.09). DISCUSSION AND CONCLUSIONS The high incidence of probable depression is a concern that warrants interventions, as depression has lasting harmful effects in adolescents. Baseline probable depression predicted IA at follow-up and vice versa, among those who were free from IA/probable depression at baseline. Healthcare workers, teachers, and parents need to be made aware of this bidirectional finding. Interventions, both IA and depression prevention, should thus take both problems into consideration.

Abstract
BACKGROUND AND AIMS The aim of this study is to estimate the longitudinal associations between online social networking addiction (OSNA) and depression, whether OSNA predicts development of depression, and reversely, whether depression predicts development of OSNA. METHODS A total of 5,365 students from nine secondary schools in Guangzhou, Southern China were surveyed at baseline in March 2014, and followed up 9 months later. Level of OSNA and depression were measured using the validated OSNA scale and CES-D, respectively. Multilevel logistic regression models were applied to estimate the longitudinal associations between OSNA and depression. RESULTS Adolescents who were depressed but free of OSNA at baseline had 1.48 times more likely to develop OSNA at follow-up compared with those non-depressed at baseline [adjusted OR (AOR): 1.48, 95% confidence interval (CI): 1.14-1.93]. In addition, compared with those who were not depressed during the follow-up period, adolescents who were persistently depressed or emerging depressed during the follow-up period had increased risk of developing OSNA at follow-up (AOR: 3.45, 95% CI: 2.51-4.75 for persistent depression; AOR: 4.47, 95% CI: 3.33-5.99 for emerging depression). Reversely, among those without depression at baseline, adolescents who were classified as persistent OSNA or emerging OSNA had higher risk of developing depression compared with those who were no OSNA (AOR: 1.65, 95% CI: 1.01-2.69 for persistent OSNA; AOR: 4.29; 95% CI: 3.17-5.81 for emerging OSNA). CONCLUSION The findings indicate a bidirectional association between OSNA and depression, meaning that addictive online social networking use is accompanied by increased level of depressive symptoms.

Abstract
HIV self-stigma in HIV positive men who have sex with men (HIVMSM) has been identified as one of the largest challenges of HIV prevention, and associates with numerous negative outcomes, including depression, decreased social support, and less condom use intentions. In the present study, 321 HIVMSM in Chengdu, China were recruited to examine the prevalence of condom use in the past months and intentions to use condoms in next six months; we also identify pathways between HIV self-stigma and intentions to use condoms by the structural equation modeling approach. Results showed that Chinese HIVMSM had the suboptimal prevalence of consistent condom use and low intentions to use condoms consistently. Additionally, depression and decreased social support were significant mediators between HIV self-stigma and condom use intentions. The complex pathways between HIV self-stigma and intentions to use condoms should be taken into account in the HIV prevention and intervention programs.

Abstract
Suicide is a leading cause of death in adolescence. School provides an effective avenue both for reaching adolescents and for gatekeeper training. This enables gatekeepers to recognize and respond to at-risk students and is a meaningful focus for the provision of suicide prevention. This study provides the first systematic review on the effectiveness of school-based gatekeeper training in enhancing gatekeeper-related outcomes. A total of 815 studies were identified through four databases (Ovid Medline, Embase, PsycINFO and ERIC) using three groups of keywords: 'school based', 'Suicide prevention programme' and 'Gatekeeper'. Fourteen of these studies were found to be adequate for inclusion in this systematic review. The improvement in gatekeepers' knowledge; attitudes; self-efficacy; skills; and likelihood to intervene were found in most of the included studies. Evidence of achieving improvement in attitudes and gatekeeper behaviour was mixed. Most included studies were methodologically weak. Gatekeeper training appears to have the potential to change participants' knowledge and skills in suicide prevention, but more studies of better quality are needed to determine its effectiveness in changing gatekeepers' attitudes. There is also an urgent need to investigate how best improvements in knowledge and skills can be translated into behavioural change.

Abstract
Newly diagnosed HIV-positive men who have sex with men (NHMSM) are at high risk of mental health problems but may also develop post-traumatic growth (PTG). According to the Common Sense Model, illness perception (including both cognitive representation and emotional representation) affects coping and health-related outcomes. A cross-sectional survey was conducted to examine the associations between illness perception and PTG among 225 NHMSM in Chengdu, China. Linear regression analyses indicated that the constructs of emotional representation subscale (β = -0.49) and five cognitive representation subscales (timeline, consequence, identity, attribution to god's punishment/will, and attribution to chance/luck) (β = -0.13 to -0.37) were negative correlates of PTG, while four other constructs of cognitive representation (coherence, treatment control, personal control, and attribution to carelessness) were positive correlates (β = 0.15 to 0.51). No moderating effects were observed. The associations between five cognitive representation subscales and PTG were fully-mediated via emotional representation. The results indicate that interventions promoting PTG among NHMSM are warranted and should alter illness perception, emotional representation in particular. Future studies should clarify relationships between cognitive representation and emotional representation, and extend similar research to other health-related outcomes and HIV-positive populations.

Abstract
Young female sex workers (YFSWs) are confronted with significant threats during sex work. The present cross-sectional study examined different levels of threats (i.e., threats to life and health, threats to humanity, threats to control of work and financial security, and the threats to future) experienced by 87 YFSWs (age 16-25) in Hong Kong, and identified their association with mental health (i.e., psychological well-being) together with other factors, including childhood trauma, self-efficacy, hope, and social support. Results showed that the participants encountered a significant number of threats. More than half reported that they had a condom removed by clients during sex (51.7%); or have been humililated by clients (51.7%). Because of sex work, about a quarter (25.3%) have had sexually transmitted disease, and respectively 10.3% and 12.6% have had abortion and unplanned pregnancy. The majority have had friends found out that they engaged in sex work (72.4%). They also showed a high level of worry about the various threats. Multiple linear regression analysis showed that childhood trauma (β = -.26) and worry about threats during sex work (β = -.22) were significantly negative predictors, while self-efficacy (β = .20) and hope (β = .27) were significantly positive predictors of mental health. Future services should improve YFSWs' skills to minimize potential threats during female sex work, address the structural correlates and relieve their worries, and empower them with more hope and self-efficacy in choosing clients.

Abstract
Background Newly diagnosed HIV-positive men who have sex with men (MSM) are an important subgroup in HIV intervention. How newly diagnosed HIV-positive MSM look at HIV/AIDS is consequential and is potentially associated with their risk behaviors and mental health problems. Illness representation has been used to define patients’ beliefs and expectations on an illness, and the revised Illness Perception Questionnaire (IPQ-R) has been developed to measure illness representations. This study aims to examine the psychometric properties of the IPQ-R among newly diagnosed HIV-positive MSM and to investigate their views towards HIV/AIDS. Method A total of 225 newly diagnosed HIV-positive MSM completed the Chinese version of IPQ-R. Both confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were applied to examine the factor structure of IPQ-R. Results CFA showed a poor goodness of fit to the original factor structure of IPQ-R. EFA of the IPQ-R revealed 7 factors, including Emotional Response, Treatment Control, Timeline-acute/chronic, Illness Coherence, Consequence, Personal Control and Helplessness. Cronbach’s alpha showed acceptable internal consistency for the derived factors, except the Personal Control (0.61) and Helplessness (0.55). Person correlation coefficients demonstrated that the derived factors of IPQ-R had significant associations with the outcome variables (depression and posttraumatic growth). The scores of the Emotional Response, Consequence, Treatment Control, Personal Control, Timeline-acute/chronic and Illness Coherence were above the midpoint, and the score of the Helplessness was below the midpoint. Conclusion Both similarities and differences were found when the IPQ-R is applied to newly diagnosed HIV-positive MSM. The IPQ-R can be used with some refinements in future studies. Newly diagnosed HIV-positive MSM have a relatively high level of negative perceptions towards HIV/AIDS in both cognitive and emotional aspects.

Abstract
Background and aims This study aims to examine the mediating effects of insomnia on the associations between problematic Internet use, including Internet addiction (IA) and online social networking addiction (OSNA), and depression among adolescents. Methods A total of 1,015 secondary school students from Guangzhou in China participated in a cross-sectional survey. Levels of depression, insomnia, IA, and OSNA were assessed using the Center for Epidemiological Studies-Depression Scale, Pittsburgh Sleep Quality Index, Young's Diagnostic Questionnaire, and Online Social Networking Addiction Scale, respectively. Logistic regression models were fit to test the associations between IA, OSNA, insomnia, and depression. The mediation effects of insomnia were tested using Baron and Kenny's strategy. Results The prevalence of depression at moderate level or above (CES-D ≥ 21), insomnia, IA, and OSNA were 23.5%, 37.2%, 8.1%, and 25.5%, respectively. IA and OSNA were significantly associated with depression (IA: AOR = 2.79, 95% CI: 1.71, 4.55; OSNA: AOR = 3.27, 95% CI: 2.33, 4.59) and insomnia (IA: AOR = 2.83, 95% CI: 1.72, 4.65; OSNA: AOR = 2.19, 95% CI: 1.61, 2.96), after adjusting for significant background factors. Furthermore, insomnia partially mediated 60.6% of the effect of IA on depression (Sobel Z = 3.562, p < .002) and 44.8% of the effect of OSNA on depression (Sobel Z = 3.919, p < .001), respectively. Discussion The high prevalence of IA and OSNA may be associated with increased risk of developing depression among adolescents, both through direct and indirect effects (via insomnia). Findings from this study indicated that it may be effective to develop and implement interventions that jointly consider the problematic Internet use, insomnia, and depression.

Abstract
OBJECTIVE The present study conducted a meta-analysis and systematic review on studies evaluating the effectiveness of stigma reduction programs in improving knowledge and reducing negative attitudes towards people living with HIV (PLHIV). RESULTS Meta-analysis (k = 42 studies) found significant and small effect sizes in the improvement of the participants' knowledge of HIV/AIDS from interventions with (Cohen's d = 0.48, 95% CI [0.30, 0.66]) and without control groups (Cohen's d = 0.42, 95% CI [0.28, 0.57]). Significant and small effect sizes were found in the improvement of the participants' attitudes toward PLHIV from interventions with (Cohen's d = 0.39, 95% CI [0.23, 0.55]) and without control groups (Cohen's d = 0.25, 95% CI [0.11, 0.39]). Significant and small effect sizes were sustained at the follow-up assessments. Subgroup analysis showed that number of intervention sessions, intervention settings, and sample type significantly moderated the effect sizes in the meta-analysis. Findings from the systematic review of 35 studies indicated that most of the included studies showed positive results in reducing negative attitudes toward PLHIV and improving HIV-related knowledge. Most of the included studies tended to have low methodological quality. CONCLUSION The present meta-analysis and systematic review indicated that the studies generally found small improvement in HIV-related knowledge and reduction in negative attitudes towards PLHIV among the stigma reduction programs being evaluated. High-quality stigma reduction programs with multidimensional stigma indicators and psychometrically sound outcome measures are highly warranted.
