Electronic health literacy and health-related outcomes among older adults: A systematic review.

This review aims to identify, appraise, and synthesize research evidence of the association between electronic health (eHealth) literacy and health outcomes in older adults. English-written articles that presented the relationships between eHealth literacy and health-related outcomes in older adults were identified by searching five scientific databases (Web of Science, PubMed, Cochrane Library, APA PsycInfo, and EMBASE) hand-searching reference lists. Searches yielded 2993 studies after duplicates were removed, of which 24 publications were included in the final review. eHealth literacy was relatively low in older adults, and the eHealth Literacy Scale, developed by Norman and Skinner in 2006, was the most frequently used instrument in the included studies (21/24, 87.5%). The health-related outcomes associated with eHealth literacy were grouped into four categories: physical, behavioral, psychosocial, and cognitive. For behavioral (e.g., health-promoting behaviors, self-care, and medication adherence) and cognitive (e.g., health knowledge and health decision making) outcomes, the evidence was mostly consistent that eHealth literacy was positively associated with better outcomes. For physical (e.g., health-related quality of life) and psychosocial outcomes (e.g., anxiety and self-efficacy), the associations were less consistent, with some studies showing significant associations while others showed no associations. Most included studies were assessed as moderate quality. Overall, higher eHealth literacy is associated with more positive health behaviors and better health knowledge and attitude in older adults, however, the associations with some physical and psychosocial outcomes are less consistent. Clarifying the pathways of the relationships between eHealth literacy and some health-related outcomes is needed for further exploring their underlying mechanisms.

The associations among cognitive social factors, eHealth literacy and health-promoting behaviors in Chinese adolescents.

The internet is a critical source of health information. It is important to understand online health information seeking related factors among college students, as modifications in this have the potentials to enhance their health-promoting behaviors in their transition into early adulthood. This study assessed the associations among cognitive social factors, eHealth literacy, online health information seeking and health-promoting behaviors; and examined the potential mediation effect of online health information seeking and eHealth literacy on the association between cognitive social factors and health-promoting behaviors. A cross-sectional, Internet-based survey was conducted in a sample of Chinese college students (n = 289) during April to June 2018. The structural model fitted the data well: X2/df = 2.27; CFI = 0.95; TLI = 0.94; RMSEA = 0.07 (95% CI: 0.06, 0.08); SRMR = 0.07 and the results showed that performance expectancy and health motivation were significantly and positively associated with health-promoting behaviors indirectly through eHealth literacy, adjusting for other cognitive social factors, frequency of online health information seeking and background factors. eHealth literacy is a strong mediator of the association between cognitive social factors (performance expectancy and health motivation) and health-promoting behaviors. Implications and potential interventions to promote eHealth literacy and health-promoting behaviors are discussed.

Impact of Minority Stress and Poor Mental Health on Sexual Risk Behaviors among Transgender Women Sex Workers in Shenyang, China.

This study examined the associations between minority stressors, poor mental health, and sexual risk behaviors, and whether there were interactive effects of minority stress and mental health factors in their associations with sexual risk behaviors in a sample of Chinese transgender women sex workers (TGSW). A cross-sectional study was conducted in 204 TGSW in Shenyang, China (mean age 33.4 years and 18.1% self-reported as HIV positive). We found a high prevalence of condomless anal intercourse (CAI) with male clients (27.9%) and CAI with male regular partners (49.5%) in the past three months among TGSW. Multivariate logistic regression analysis showed that discrimination, victimization, and life dissatisfaction were significantly associated with higher odds of CAI with male clients (AOR range: 1.05-1.42, all p < 0.05). Likewise, CAI with male regular partners was more frequently reported by participants who experienced higher levels of victimization, rejection, and anxiety (AOR range: 1.37-2.88, all p < 0.05). No significant interaction effects of gender minority stress and mental health on sexual behaviors were observed. Interventions addressing the multiple psychosocial risks are warranted to prevent behavioral risks of TGSW.

Same-sex behavior disclosure to health care providers associated with greater awareness of pre-exposure prophylaxis.

BACKGROUND: This study aimed to determine whether the disclosure of same-sex behavior to health care providers (HCPs) is associated with higher rates of prior human immunodeficiency virus (HIV) testing experience and greater awareness of immediate antiretroviral therapy (ART), Undetectable = Untransmittable (U=U), and pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM). METHODS: We conducted a cross-sectional survey among 689 adult males in Chengdu, China who self-reported having had anal intercourse with at least one man in the past 6 months. We measured same-sex behavior disclosure to three types of HCPs (hospital clinicians, community-based organization peer educators, and Center for Disease Control and Prevention public health specialists), and the awareness of immediate ART, U=U, and PrEP. RESULTS: Of the 689 enrolled participants, 31.4% had disclosed their same-sex behavior to some or all of the clinicians, 83.9% had done so to the peer educators, and 56.8% had done so to the public health specialists. Approximately four in five (82.1%) of the participants had ever been tested for HIV. The awareness rate was 84.8% for immediate ART, 20.2% for U=U, and 50.7% for PrEP. After controlling for significant background variables, same-sex behavior disclosure to clinicians was associated with greater awareness of PrEP (adjusted odds ratio [AOR] = 1.64; 95% confidence interval [CI]: 1.08-2.48), but similar findings were not reported regarding disclosure to peer educators or public health specialist. Same-sex behavior disclosure to any types of HCPs was not associated with HIV testing experience, and awareness of immediate ART or U=U. CONCLUSIONS: The rates of same-sex behavior disclosure varied with different types of HCPs. Disclosure to clinicians was associated with greater awareness of PrEP, but not awareness of immediate ART or U=U.

Impulsivity, Self-control, Interpersonal Influences, and Maladaptive Cognitions as Factors of Internet Gaming Disorder Among Adolescents in China: Cross-sectional Mediation Study.

BACKGROUND: Gaming disorder, including internet gaming disorder (IGD), was recently defined by the World Health Organization as a mental disease in the 11th Revision of the International Classification of Diseases (ICD-11). Thus, reducing IGD is warranted. Maladaptive cognitions related to internet gaming (MCIG) have been associated with IGD, while impulsivity, self-control, parental influences, and peer influences are key risk factors of IGD. Previous literature suggests that MCIG is associated with the aforementioned 4 risk factors and IGD, and may thus mediate between these risk factors and IGD. These potential mediations, if significant, imply that modification of MCIG may possibly alleviate these risk factors' harmful impacts on increasing IGD. These mediation hypotheses were tested in this study for the first time. OBJECTIVE: This study tested the mediation effects of MCIG between intrapersonal factors (impulsivity and self-control) and IGD, and between interpersonal factors (parental influences and peer influences) and IGD among adolescents in China. METHODS: An anonymous, cross-sectional, and self-administered survey was conducted among secondary school students in classroom settings in Guangzhou and Chengdu, China. All grade 7 to 9 students (7 to 9 years of formal education) of 7 secondary schools were invited to join the study, and 3087 completed the survey. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) checklist was used to assess IGD. MCIG was assessed by using the Chinese version of the Revised Internet Gaming Cognition Scale. Impulsivity, self-control, and parental or peer influences were measured by using the motor subscale of the Barratt Impulsiveness Scale, the Brief Self-Control Scale, and the modified interpersonal influence scale, respectively. Structural equation modeling was conducted to examine the mediation effects of MCIG between these risk factors and IGD. RESULTS: The prevalence of IGD was 13.57% (418/3081) and 17.67% (366/2071) among all participants and adolescent internet gamers, respectively. The 3 types of MCIG (perceived rewards of internet gaming, perceived urges for playing internet games, and perceived unwillingness to stop playing without completion of gaming tasks) were positively associated with IGD. Impulsivity, self-control, parental influences, and peer influences were all significantly associated with the 3 types of MCIG and IGD. The 3 types of MCIG partially mediated the associations between the studied factors and IGD (effect size of 30.0% to 37.8%). CONCLUSIONS: Impulsivity, self-control, and interpersonal influences had both direct and indirect effects via MCIG on IGD. Modifications of the 3 types of MCIG can potentially reduce the harmful impacts of impulsivity and interpersonal influences on IGD and enhance the protective effect of self-control against IGD. Future longitudinal studies are warranted.

Association of Perceived Threat, Negative Emotions, and Self-Efficacy With Mental Health and Personal Protective Behavior Among Chinese Pregnant Women During the COVID-19 Pandemic: Cross-sectional Survey Study.

BACKGROUND: COVID-19 is an emerging infectious disease that has created health care challenges worldwide. Pregnant women are particularly affected by this disease. OBJECTIVE: The aims of this study are to assess the levels of perceived threat (susceptibility, severity, impact), negative emotions (fear, worry), and self-efficacy of pregnant women in China related to COVID-19 and to examine their associations with mental health (depression and anxiety) and personal protective behavior (wearing a face mask). METHODS: A total of 4087 pregnant women from China completed a cross-sectional web-based survey between March 3 and 10, 2020. RESULTS: The prevalence of probable depression and anxiety was 48.7% (1989/4087) and 33.0% (1347/4087), respectively; 23.8% participants (974/4087) reported always wearing a face mask when going out. Of the 4087 participants, 32.1% (1313) and 36.4% (1490) perceived themselves or their family members to be susceptible to COVID-19 infection, respectively; 3216-3518 (78.7%-86.1%) agreed the disease would have various severe consequences. Additionally, 2275 of the 4087 participants (55.7%) showed self-efficacy in protecting themselves from contracting COVID-19, and 2232 (54.6%) showed efficacy in protecting their family members; 1303 (31.9%) reported a high level of fear of the disease, and 2780-3056 (68.0%-74.8%) expressed worry about various aspects of COVID-19. The results of the multivariate multinominal logistic regression analyses showed that perceived severity, perceived impact, fear, and worry were risk factors for probable depression and anxiety, while self-efficacy was a protective factor. The results of the multivariate logistic regression analysis showed that perceived susceptibility was associated with always wearing a face mask. CONCLUSIONS: Chinese pregnant women showed high levels of mental distress but low levels of personal protective behavior during the COVID-19 pandemic. Interventions are needed to promote the mental health and health behavior of pregnant women during the pandemic.

Web-Based Behavioral Intervention Utilizing Narrative Persuasion for HIV Prevention Among Chinese Men Who Have Sex With Men (HeHe Talks Project): Intervention Development.

BACKGROUND: In the era of potent antiretroviral therapy, a high level of condomless anal intercourse continues to drive increases in HIV incidence in recent years among men who have sex with men. Effective behavior change strategies for promoting HIV-preventive behaviors are warranted. Narrative persuasion is a novel health communication approach that has demonstrated its persuasive advantages in overcoming resistance to counterattitudinal messages. The efficacy of narrative persuasion in promoting health behavior changes has been well documented, but critical research gaps exist for its application to HIV prevention. OBJECTIVE: In this study, we aimed to (1) capitalize on narrative persuasion to design a web-based multisession intervention for reducing condomless anal intercourse among men who have sex with men in Hong Kong (the HeHe Talks Project) by following a systematic development process; and (2) describe the main components of the narrative intervention that potentially determine its persuasiveness. METHODS: Persuasive themes and subtopics related to reducing condomless anal intercourse were initially proposed based on epidemiological evidence. The biographic narrative interview method was used to elicit firsthand experiential stories from a maximum variation sample of local men who have sex with men with diverse backgrounds and experiences related to HIV prevention; different types of role models were established accordingly. Framework analysis was used to aggregate the original quotations from narrators into collective narratives under 6 intervention themes. A dedicated website was finally developed for intervention delivery. RESULTS: A series of video-based intervention messages in biographic narrative format (firsthand experiential stories shared by men who have sex with men) combined with topic-equivalent argumentative messages were produced and programmed into 6 intervention sessions. The 6-week intervention program can be automatically delivered and monitored online. CONCLUSIONS: We systematically created a web-based HIV prevention intervention derived from peer-generated stories. Strategies used to enhance the efficacy of the narrative intervention have been discussed within basic communication components. This paper describes the methods and experiences of the rigorous development of a narrative communication intervention for HIV prevention, which enables replication of the intervention in the future.

The Effectiveness of Electronic Health Interventions for Promoting HIV-Preventive Behaviors Among Men Who Have Sex With Men: Meta-Analysis Based on an Integrative Framework of Design and Implementation Features.

BACKGROUND: The disproportionately high prevalence of HIV among men who have sex with men (MSM) is a global concern. Despite the increasing utilization of electronic health (eHealth) technology in the delivery of HIV prevention interventions, few studies have systematically explored its effectiveness and association with various intervention characteristics. OBJECTIVE: This study aimed to conduct a meta-analysis of the effectiveness of eHealth technology-based interventions for promoting HIV-preventive behaviors among MSM and to determine effectiveness predictors within a framework integrating design and implementation features. METHODS: A systematic literature search using terms related to eHealth technology, HIV, the MSM population, and an experimental study design was performed using 5 databases (ie, MEDLINE, PsycINFO, EMBASE, Web of Science, and ProQuest Dissertations & Theses) and other sources (eg, bibliographies of relevant reviews and JMIR Publications). First, primary meta-analyses were conducted to estimate the effectiveness of eHealth interventions (d+) in changing 3 HIV-preventive behaviors among MSM: unprotected anal intercourse (UAI), HIV testing, and multiple sex partnership (MSP). Moderation analyses were then conducted to examine a priori effectiveness predictors including behavioral treatment components (eg, theory use, tailoring strategy use, navigation style, and treatment duration), eHealth technology components (eg, operation mode and modality type), and intervention adherence. RESULTS: A total of 46 studies were included. The overall effect sizes at end point were small but significant for all outcomes (UAI: d+=-.21, P<.001; HIV testing: d+=.38, P<.001; MSP: d+=-.26, P=.02). The intervention effects on UAI were significantly larger when compared with preintervention groups than with concurrent groups. Greater UAI reductions were associated with the increased use of tailoring strategies, provision of feedback, and tunneling navigation in interventions with a concurrent group, whereas reductions were associated with the use of self-paced navigation in interventions with a preintervention group. Greater uptake of HIV testing was associated with longer treatment duration; computer-mediated communication; and the use of messaging, social media, or a combined technology modality. Higher intervention adherence consistently predicted larger effects on UAI and HIV testing. CONCLUSIONS: This study provided empirical evidence for the effectiveness of eHealth interventions in promoting HIV-preventive behaviors among MSM. Features of treatment content and eHealth technology might best predict the intervention effects on UAI and HIV testing, respectively. Most importantly, intervention adherence tended to play an important role in achieving better effectiveness. The findings could help inform the development of efficacious interventions for HIV prevention in the future.

Validation of the Outcome Expectancy Scale for HIV Serostatus Disclosure to Female Sex Partners Among Men Who Have Sex with Men and Women Living with HIV in China.

The study aimed to develop an instrument, Outcome Expectancy Scale (OES), to assess outcome expectancies regarding disclosing HIV-positive status to the regular female sex partner (i.e. girlfriend, wife) based on a cross-sectional survey among 217 men who have sex with men and women living with HIV. We developed the positive OES and negative OES, and five factors were identified for each of them by the Exploratory Factor Analysis, respectively. The psychometric properties were satisfactory. This 30-item OES was valid and reliable in assessing outcome expectancies, and it could be used to inform intervention design and theory development.

Relationship between illness representations and mental health among HIV-positive men who have sex with men.

Illness representations play a significant role on mental health across various health conditions. The present study explores the associations between illness representations of HIV and mental health (suicidal ideation and depression), and the mediation effects of emotional representations on the associations between cognitive representations and mental health among men who have sex with men who were newly diagnosed with HIV (ND-MSM) in China. A total of 225 ND-MSM were recruited from a non-governmental organisation and were invited to complete a cross-sectional survey. Results showed that 48.0% had suicidal ideation since HIV diagnosis and 48.4% scored higher than the cut-off for mild depression or above. Stepwise regression analyses showed that higher levels of emotional representations of HIV and lower levels of treatment control were associated with both suicidal ideation and depression. Emotional representations were shown to mediate the associations between some cognitive representations variables and mental health. Findings suggest that both cognitive and emotional representations of HIV were important factors of mental health among ND-MSM. Interventions to promote the mental health of ND-MSM are warranted and should seek to improve their cognitive and emotional representations of HIV.

The role of social support on resilience, posttraumatic growth, hopelessness, and depression among children of HIV-infected parents in mainland China.

Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has a profound impact not only on the infected individuals, but also on their families. Children of the HIV-infected parents are particularly affected. The present study examined the relationship between social support, resilience, posttraumatic growth (PTG), hopelessness, and depression among 195 children of HIV-infected parents in mainland China. Results showed that 35.4% of the sample scored above the cutoff of the Children's Depression Inventory. Results from structural equation modeling reported that social support had a significant positive relationship with resilience and PTG. Higher levels of resilience and PTG were associated with lower level of hopelessness which in turn, was associated with lower level of depression. The overall model achieved satisfactory fit. Interventions are needed to improve social support of the children affected by HIV so as to improve their mental health.

Common stressors, coping processes, and professional help-seeking of medical professionals in Hong Kong: A qualitative study.

Despite the high prevalence of perceived stress and mental health problems among medical professionals (MPs), their professional help-seeking is extremely low. This qualitative study explored MPs' stressors, stress-coping, barriers and facilitators of professional help-seeking. 10 MPs (30% male, Mage = 34.8 years) were recruited by purposive-sampling for views from different roles/settings. Thematic analyses revealed five central stressors: emerging novel diseases, challenges from technology-advancement, patient-communication difficulties, lack of workplace mental health care culture, excessive workload/manpower shortage. Participants predominantly used peer support/supervision and de-stress activities for stress-coping. Five factors affecting professional help-seeking were time constraint versus flexibility, mental health stigma versus de-stigmatization, concern over confidentiality/anonymity versus sense of privacy, worry about damage on professional role versus least work disruption, doubts of service providers versus perceived efficacy. All participants indicated a preference for online mental health service delivery. Results reflected unmet needs and service gaps from MPs' perspectives for the development of future interventions.

Social Support, Resilience, and Mental Health Among Three High-Risk Groups in Hong Kong: A Mediation Analysis.

Objectives: To compare the prevalence of anxiety/depression, resilience, and social support among nurses, foreign domestic helpers (FDHs), and residents living in subdivided units (SDUs), and to examine their associations in these high-risk groups in Hong Kong during Omicron waves. Methods: We recruited 1,014 nurses, 621 FDHs, and 651 SDU residents from December 2021 to May 2022 in this cross-sectional survey. The depression, anxiety, social support, and resilience levels were measured by the validated scales. The multivariate binary logistic regression and causal mediation analysis were applied to examine the associations. Results: We observed a prevalence of 17.7% in anxiety and 21.6% in depression which were the highest in SDU residents, followed by FDHs, and lowest in nurses. Social support was associated with increased resilience levels and decreased risks of anxiety/depression. The association of social support with mental disorders was partly mediated by resilience, accounting for 30.9% and 20.9% of the total effect of social support on anxiety and depression, respectively. Conclusion: Public health strategies should target improving social support and providing resilience-promoting interventions to help reduce mental disorders in vulnerable groups.

Patient preferences in the treatment of chronic musculoskeletal pain: a systematic review of discrete choice experiments.

ABSTRACT: Chronic musculoskeletal pain (CMP) is a preference-sensitive condition for which numerous treatment options are available, each with benefits and risks. Thus, patient preferences play a critical role in decision making. This study summarized evidence from discrete choice experiments (DCEs) to quantify patient preferences for CMP treatment and identified important treatment attributes. A systematic review of DCEs on patient preferences for CMP treatment was conducted. Studies were included if they used DCE to determine patient preferences for CMP. A previously described methodological assessment tool was used to assess the risk of bias. The treatment attributes were summarized and sorted according to the frequency of citation and relative weight. Subgroup analyses were conducted to explore the intervention-specific attributes. A total of 15 eligible studies with 4065 participants were included. We identified "capacity to realize daily life activities," "risk of adverse events," "effectiveness in pain reduction," and "out-of-pocket cost" as important attributes. Although "treatment frequency" and "onset of treatment efficacy" were less frequently mentioned, they were also important attributes. The attribute of "risk of adverse events" was especially important for drug treatment. The "out-of-pocket cost" and "treatment location and mode" were important attributes of exercise therapy. The attributes identified in this review will inform the design of future DCE studies, facilitate the translation of measurement-based care to value-based care, and provide the rationale to promote shared decision making and patient-centered care.

Parental Acceptance, Parental Hesitancy, and Uptake of Seasonal Influenza Vaccination among Children Aged 6-59 Months: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis summarises the literature on parental acceptance, parental hesitancy, uptake, and the associated factors of seasonal influenza vaccination (SIV) among children aged 6-59 months. Studies were sourced from the following platforms: PubMed, Web of Science, MEDLINE, and EMBASE databases. A random-effects model was used to evaluate the prevalence and 95% confidence intervals (CI) of parental acceptance, parental hesitancy, and SIV uptake in the last flu season and lifetime among children. A total of 36 studies were included for analysis. The overall prevalence was 64% for parental acceptance (95% CI: 51-75%), 34% for parental hesitancy (95% CI: 22-48%), 41% for SIV uptake in the last flu season (95% CI: 33-50%), and 46% for SIV uptake in a lifetime (95% CI: 20-74%). Associated factors of parental acceptance/hesitancy and uptake included the age of the children or parents, parental education level, household income level, ethnicity, and other modifiable factors, including perceived benefits, perceived barriers, perceived severity, perceived susceptibility, and cues to action related to SIV. Meta-regression analyses revealed regional differences in parental acceptance (Americas: 79% vs. Asia: 60%). The results provided implications informing us of the development of intervention programs targeting parents to improve SIV coverage among young children.

Associations between Health Literacy, Trust, and COVID-19 Vaccine Hesitancy: The Case of Hong Kong.

This study investigates how health literacy (HL) and trust in health information affected COVID-19 vaccine hesitancy among Chinese Hong Kong adults. A cross-sectional study was conducted in August 2022. A total of 401 participants completed the study. Participants completed a newly developed Hong Kong HL scale and self-reported their trust levels in health information from different resources. The proportions of early uptake of the first dose and booster dose of COVID-19 vaccine were 69.1% and 71.8%, respectively. The risk of delaying the first dose was higher among participants with inadequate functional HL (OR = 0.58, p = 0.015), adequate levels of two subdomains of critical HL (OR = 1.82, p = 0.013; OR = 1.91, p < 0.01), and low-level trust in health information from the government (OR = 0.57, p = 0.019). Respondents with adequate interactive HL (OR = 0.52, p = 0.014) and inadequate level of one subdomain of critical HL (OR =1.71, p = 0.039) were more likely to delay the booster dose. This negative association between critical HL and vaccination was suppressed by trust in health information from the government. This study shows that HL and trust in health information from the government are associated with COVID-19 vaccine hesitancy. Efforts should be directed at providing tailored communication strategies with regard to people's HL and increasing public confidence in health authorities to decrease vaccine hesitancy.

Chinese Mothers' Intent to Disclose Their HIV Status to Their Children: The Role of Positive Outcome Expectations and Reward Responsiveness.

Objective: The current study investigated the role of positive outcome expectations and reward responsiveness in intention to disclose HIV status to children among women living with HIV in China. The moderating role of reward responsiveness was also explored. Method: A 1-year longitudinal survey was conducted. 269 women living with HIV who had at least one child aged >5 years and had not yet disclosed their HIV status to their oldest child were selected from a larger sample of women living with HIV at baseline, with a total of 261 respondents completing the follow-up survey. Results: After adjusting for significant socio-demographic and medical variables, positive outcome expectations positively predicted mothers' intention to disclose HIV, while reward responsiveness had a negative effect. A moderation effect of reward responsiveness was found, with further analysis showing that reward responsiveness has strengthened the relationship between positive outcome expectations and intention to disclose HIV. Conclusion: Findings support the relevance of positive outcome expectations and reward responsiveness to intention of disclosure among women living with HIV in China.

Effects of Social Media Use for Health Information on COVID-19-Related Risk Perceptions and Mental Health During Pregnancy: Web-Based Survey.

BACKGROUND: Social media has become an important source of health information during the COVID-19 pandemic. Very little is known about the potential mental impact of social media use on pregnant women. OBJECTIVE: This study aims to examine the association between using social media for health information and risk perception for COVID-19, worry due to COVID-19, and depression among pregnant women in China. METHODS: A total of 4580 pregnant women were recruited from various provinces of China. The participants completed a cross-sectional, web-based survey in March 2020. RESULTS: More than one-third (1794/4580, 39.2%) of the participants reported always using social media for obtaining health information. Results of structural equation modeling showed that the frequency of social media use for health information was positively associated with perceived susceptibility (ß=.05; P<.001) and perceived severity (ß=.12; P<.001) of COVID-19, which, in turn, were positively associated with worry due to COVID-19 (ß=.19 and ß=.72, respectively; P<.001). Perceived susceptibility (ß=.09; P<.001), perceived severity (ß=.08; P<.001), and worry due to COVID-19 (ß=.15; P<.001) all had a positive association with depression. Bootstrapping analysis showed that the indirect effects of frequency of social media use for health information on both worry due to COVID-19 (ß=.09, 95% CI 0.07-0.12) and depression (ß=.05, 95% CI 0.02-0.07) were statistically significant. CONCLUSIONS: This study provides empirical evidence on how social media use for health information might have a negative impact on the mental health of pregnant women. Interventions are needed to equip this population with the skills to use social media properly and with caution.

The associations between psychological needs, health-related quality of life and subjective well-being among Chinese older people: A cross-sectional study.

The present study investigated the associations between the three psychological needs (autonomy, competence and relatedness) derived from the Self-determination Theory and well-being [health-related quality of life (HRQOL) and subjective well-being (SWB)] among older people in Hong Kong SAR, China. A cross-sectional study was conducted from May to August 2018 in Hong Kong. A total of 230 participants aged 60-year-old or above were recruited from eight community service centres. Results from adjusted regression analysis showed that, among the three psychological needs, competence and relatedness were positively associated with SWB, while relatedness was positively associated with physical health domain of HRQOL. The three psychological needs had no significant associations with mental health domain of HRQOL. Interventions to improve HRQOL and SWB should promote older people's sense of competence and relatedness. Longitudinal studies are warranted to clarify the causal relationships and look at other physical, mental and social health outcomes.

Development and validation of a comprehensive health literacy tool for adults in Hong Kong.

Introduction: Health literacy (HL) refers to an individual's ability to process and use health information to make health-related decisions. However, previous HL scales did not fully cover all aspects of this concept. This study aimed to develop a comprehensive Hong Kong HL scale (HLS-HK) and evaluate its psychometric properties among Chinese adults. Methods: A scale of 31-item covering Nutbeam's framework, namely functional and interactive HL (FHL and IHL), and critical HL (CHL) within three subdomains: critical appraisal of information, understanding of social determinants of health, and actions to address social determinants of health, was developed based on previous literature review and Delphi survey. Cognitive interviews were performed to examine all items' face validity in terms of three aspects: comprehensiveness, clarity, and acceptability. A cross-sectional survey was conducted to investigate the scale's psychometric properties, including its internal consistency reliability, factorial structure validity, convergent validity, and predictive validity. Results: Nine interviewees participated in the cognitive interviews in October 2021. Based on the input from respondents, two items were deleted, two items were combined, and several items' wording was revised. The other items were clear and readable. Finally, 28 items remained. A total of 433 adults completed the questionnaire survey between December 2021 and February 2022. After excluding one item with low inter-item correlations, the scale's internal consistency reliability was acceptable, with a Cronbach's alpha of 0.89. Exploratory factor analysis produced a five-factor model, as shown in the original theoretical framework. These factors accounted for 53% of the total variance. Confirmatory factor analysis confirmed that the fit indices for this model were acceptable (comparative fit index = 0.91, root mean square error of approximation = 0.06, and root mean square residual = 0.06). The scale is also significantly correlated with theoretically selected variables, including education and self-rated health. Conclusion: The HLS-HK is a valid and reliable tool for evaluating HL. Compared with existing tools, this scale extended the operationalization of FHL, IHL, and CHL and fully operationalized the CHL via three subdomains. It can be used to understand the difficulties and barriers that people may encounter when they use health-related information and services.
