Purpose
This study investigated the associations between some factors related to working from home status (WFHS) and positive/negative experiences due to social distancing and their interactions ...effects on depressive symptoms during the COVID-19 pandemic.
Methods
A random population-based telephone survey interviewed income-earning adults in the Hong Kong general population during April 21–28, 2020 (
n
= 200).
Results
Mild to severe depression (according to PHQ-9) was reported by 12% of the participants. The prevalence of WFHS categories was 14% for 3–7 days and 13% for ≥ 8 days (past 2 weeks). The multivariable regression analysis showed that, social isolation (
β
= 0.36;
p
< 0.001), relaxation feeling in daily life (
β
= − 0.22;
p
= 0.002), and WFHS ≥ 8 days (
β
= 0.15;
p
= 0.027), but not perceived huge inconvenience and improved family relationship, were associated with depressive symptoms. Statistically significant interaction effects were found. Some positive experiences buffered the potential harms of some negative experiences of social distancing on depressive symptoms; WFHS ≥ 8 days significantly moderated the risk/protective effects of social isolation, improved family relationship, and relaxation feeling on depressive symptoms.
Conclusions
Social distancing is double-edged. Positive experiences should be maximized while negative experiences be minimized, as both were directly and interactively associated with depression. Intensive but not mild to moderate (< 80%) WFHS may impact depressive symptoms negatively via its direct association with depression; it also moderated the associations between positive/negative experiences due to social distancing and depression. Further research is required to discern the inter-relationships among WFHS, positive/negative experiences of social distancing, and depression to better cope with the stressful pandemic.
During the SARS pandemic in Hong Kong, panic and worry were prevalent in the community and the general public avoided staying in public areas. Such avoidance behaviors could greatly impact daily ...routines of the community and the local economy. This study examined the prevalence of the avoidance behaviors (i.e. avoiding going out, visiting crowded places and visiting hospitals) and negative psychological responses of the general population in Hong Kong at the initial stage of the H1N1 epidemic.
A sample of 999 respondents was recruited in a population-based survey. Using random telephone numbers, respondents completed a structured questionnaire by telephone interviews at the 'pre-community spread phase' of the H1N1 epidemic in Hong Kong.
This study found that 76.5% of the respondents currently avoided going out or visiting crowded places or hospitals, whilst 15% felt much worried about contracting H1N1 and 6% showed signs of emotional distress. Females, older respondents, those having unconfirmed beliefs about modes of transmissions, and those feeling worried and emotionally distressed due to H1N1 outbreak were more likely than others to adopt some avoidance behaviors. Those who perceived high severity and susceptibility of getting H1N1 and doubted the adequacy of governmental preparedness were more likely than others to feel emotionally distressed.
The prevalence of avoidance behaviors was very high. Cognitions, including unconfirmed beliefs about modes of transmission, perceived severity and susceptibility were associated with some of the avoidance behaviors and emotional distress variables. Public health education should therefore provide clear messages to rectify relevant perceptions.
Purpose
Internet use has global influences on all aspects of life and has become a growing concern. Cross-sectional studies on Internet addiction (IA) have been reported but causality is often ...unclear. More longitudinal studies are warranted.
Methods
We investigated incidence and predictors of IA conversion among secondary school students. A 12-month longitudinal study was conducted among Hong Kong Chinese Secondary 1–4 students (
N
= 8286). Using the 26-item Chen Internet Addiction Scale (CIAS; cut-off >63), non-IA cases were identified at baseline. Conversion to IA during the follow-up period was detected, with incidence and predictors derived using multi-level models.
Results
Prevalence of IA was 16.0% at baseline and incidence of IA was 11.81 per 100 person-years (13.74 for males and 9.78 for females). Risk background factors were male sex, higher school forms, and living with only one parent, while protective background factors were having a mother/father with university education. Adjusted for all background factors, higher baseline CIAS score (ORa = 1.07), longer hours spent online for entertainment and social communication (ORa = 1.92 and 1.63 respectively), and Health Belief Model (HBM) constructs (except perceived severity of IA and perceived self-efficacy to reduce use) were significant predictors of conversion to IA (ORa = 1.07–1.45).
Conclusions
Prevalence and incidence of IA conversion were high and need attention. Interventions should take into account risk predictors identified, such as those of the HBM, and time management skills should be enhanced. Screening is warranted to identify those at high risk (e.g. high CIAS score) and provide them with primary and secondary interventions.
•From 1200 telephone interviews, the COVID-19 vaccine acceptance rate was 37.2%.•Acceptance rate was the highest in adults aged 18–24 years then increased with age.•Government recommendation was the ...strongest predictive factor of vaccine acceptance.•A key obstacle of acceptance included lack of confidence on vaccine manufacturers.•These predictors provide evidence-based formulation of vaccination strategies.
Vaccines for COVID-19 are anticipated to be available by 2021. Vaccine uptake rate is a crucial determinant for herd immunity. We examined factors associated with acceptance of vaccine based on (1). constructs of the Health Belief Model (HBM), (2). trust in the healthcare system, new vaccine platforms and manufacturers, and (3). self-reported health outcomes.
A population-based, random telephone survey was performed during the peak of the third wave of COVID-19 outbreak (27/07/2020 to 27/08/2020) in Hong Kong. All adults aged ≥ 18 years were eligible. The survey included sociodemographic details; self-report health conditions; trust scales; and self-reported health outcomes. Multivariable regression analyses were applied to examine independent associations. The primary outcome is the acceptance of the COVID-19 vaccine.
We conducted 1200 successful telephone interviews (response rate 55%). The overall vaccine acceptance rate after adjustment for population distribution was 37.2% (95% C.I. 34.5–39.9%). The projected acceptance rates exhibited a “J-shaped” pattern with age, with higher rates among young adults (18–24 years), then increased linearly with age. Multivariable regression analyses revealed that perceived severity, perceived benefits of the vaccine, cues to action, self-reported health outcomes, and trust in healthcare system or vaccine manufacturers were positive correlates of acceptance; whilst perceived access barriers and harm were negative correlates. Remarkably, perceived susceptibility to infection carried no significant association, whereas recommendation from Government (aOR = 10.2, 95% C.I. 6.54 to 15.9, p < 0.001) was as the strongest driving factor for acceptance. Other key obstacles of acceptance included lack of confidence on newer vaccine platforms (43.4%) and manufacturers without track record (52.2%), which are of particular relevance to the current context.
Governmental recommendation is an important driver, whereas perceived susceptibility is not associated with acceptance of COVID-19 vaccine. These HBM constructs and independent predictors inform evidence-based formulation and implementation of vaccination strategies.
Background. Little is known about the community psychological and behavioral responses to influenza pandemics. Methods. Using random digit dialing, we sampled 12,965 Hong Kong residents in 13 ...cross-sectional telephone surveys between April and November 2009, covering the entire first wave of the 2009 influenza A(H1N1) pandemic. We examined trends in anxiety, risk perception, knowledge on modes of transmission, and preventive behaviors. Results. Respondents reported low anxiety levels throughout the epidemic. Perceived susceptibility to infection and perceived severity of H1N1 were initially high but declined early in the epidemic and remained stable thereafter. As the epidemic grew, knowledge on modes of transmission did not improve, the adoption of hygiene measures and use of face masks did not change, and social distancing declined. Greater anxiety was associated with lower reported use of hygiene measures but greater social distancing. Knowledge that H1N1 could be spread by indirect contact was associated with greater use of hygiene measures and social distancing. Conclusion. The lack of substantial change in preventive measures or knowledge about the modes of H1N1 transmission in the general population suggests that community mitigation measures played little role in mitigating the impact of the first wave of 2009 influenza A(H1N1) pandemic in Hong Kong.
Although the pandemic has ended officially, COVID-19 remains impactful. Booster COVID-19 vaccination is still needed to protect individuals against COVID-19 and the disease’s harmful consequences. ...This study investigated the prevalence of the intention to get booster COVID-19 vaccination after receiving the COVID-19 diagnosis and its associated factors among people reporting prior COVID-19.
A population-based anonymous telephone survey was conducted in Hong Kong, China from June to August 2022 among Chinese people reporting prior COVID-1 between February and August 2022 and having taken up ≥2 doses of COVID-19 vaccines prior to COVID-19 diagnosis.
The prevalence of the intention to get booster vaccination was 59.2 %. Older age (>60 years), being currently married, not employed full-time, and having chronic diseases were positively associated with the intention to get booster vaccination. Adjusted for the background factors, higher levels of the cognitive factors of perceived susceptibility to COVID-19, perceived acquired moderate-to-strong immunity against COVID-19, and perceived adequate knowledge of COVID-19 were positively associated with the intention to get booster vaccination; stronger perceived severity of prior infection despite vaccination was negatively associated with the intention outcome. In contrast, stronger mental distress due to COVID-19, illness concern, and emotional representation were positively associated with the intention. Self-perceived long COVID status was not a significant factor.
The prevalence of the intention to get booster COVID-19 vaccination was limited, especially among younger people reporting prior COVID-19. Health promotion is still required among people reporting prior COVID-19 and may emphasize the significant cognitive factors positively associated with the intention. Future studies are needed to confirm the findings, clarify the role of emotional factors on booster vaccination, and explore other factors of the intention to get booster vaccination among people reporting prior COVID-19.
•Very low prevalence of intention of free COVID-19 vaccination (11% if 50% effectiveness) was reported.•A low proportion of participants (13%) would like to take up COVID-19 vaccination as soon as it ...becomes available.•Positive/negative outcome expectancies were associated with intention of COVID-19 vaccination.•In general, the associations involving risk perception/self-efficacy were non-significant.•Health promotion that modifies positive and negative outcomes is greatly warranted.
COVID-19 vaccination needs a high population coverage to achieve herd immunity. We investigated prevalence of three scenarios of intention of free COVID-19 vaccination involving: 1) 80% effectiveness and rare and mild side effects (Scenario 1), 2) 50% effectiveness and rare and mild side effect RMSE (Scenario 2), and 3) immediate vaccination (Scenario 3), and their associated factors derived from the pre-intentional motivational phase of the Health Action Process Approach (HAPA).
A random population-based telephone survey interviewed 450 Chinese adults in the general population (September 16–30, 2020). The four HAPA constructs included a) risk perception scale, b) overall scale/four subscales of positive outcome expectancy of COVID-19 vaccination, c) overall scale/three subscales of negative outcome expectancy of COVID-19 vaccination, and d) the overall scale/two subscales of self-efficacy of COVID-19 vaccination.
The prevalence of intention of COVID-19 vaccination under Scenarios 1 to 3 was 38.0%, 11.1%, and 13.1%, respectively. Logistic regression analyses adjusted for background factors showed that 1) the associations between risk perception and the three scenarios of intention were non-significant; 2) the overall scale/four subscales of positive outcome expectancy were in general positively associated with two scenarios of intention (80% effectiveness and immediate vaccination); 3) the overall scale/three subscales of negative outcome expectancy were in general negatively associated with all three scenarios of intention; 4) the overall scale/two subscales of self-efficacy were only positively associated with the intention that involved 80% effectiveness. When all the four overall scales were entered into an adjusted model, positive and negative outcome expectancy, but not risk perception and self-efficacy, were independently associated with the three scenarios.
In this study population, the prevalence of intention of COVID-19 vaccination was very low and might not result in population protection. Health promotion should modify outcome expectancies to increase intention of COVID-19 vaccination.
This study was to investigate the prevalence of actual uptake of pre-exposure prophylaxis (PrEP), willingness to use daily oral PrEP under two cost scenarios, and potential issues related to PrEP use ...among men who have sex with men (MSM) with HIV negative/unknown sero-status in Hong Kong, China. Factors associated with the two measures of willingness were also investigated.
403 eligible MSM completed the anonymous venue-based face-to-face interview/telephone interview.
Only 1% had ever used PrEP. After being briefed about some facts of PrEP, the prevalence of willingness to use daily oral PrEP was 7.7% if they could purchase PrEP at private hospitals/clinics at HK$8,000 (US$1,032)/month (market rate) and 45.2% if free PrEP was provided by public hospitals/clinics in Hong Kong (free PrEP). After adjusted for significant background variables, significant factors of these two measures of willingness included: (1) number of correct responses to knowledge on PrEP, (2) perceived risk of HIV infection in the next six months, and (3) constructs of the Theory of Planned Behavior: positive and negative attitudes toward PrEP, perceived their significant others would support them take PrEP (perceived subjective norm), perceived number of local MSM who were willing to take PrEP (perceived descriptive norm), and confidence in using PrEP under the two scenarios (perceived behavioral control). Among all participants, 9.7% and 25.1% would start and discontinue using PrEP without consulting doctors; 26.0% would not take PrEP daily if it was provided for free, and 42.4% would not take up HIV testing every 3 months after using PrEP.
Different strategies should be considered for promoting PrEP at market rate and if free PrEP is made available. Future promotion should increase their knowledge about PrEP, modify their perceptions related to HIV and PrEP, and address some potential issues related to PrEP use.
Online social networking use has been integrated into adolescents' daily life and the intensity of online social networking use may have important consequences on adolescents' well-being. However, ...there are few validated instruments to measure social networking use intensity. The present study aims to develop the Social Networking Activity Intensity Scale (SNAIS) and validate it among junior middle school students in China.
A total of 910 students who were social networking users were recruited from two junior middle schools in Guangzhou, and 114 students were retested after two weeks to examine the test-retest reliability. The psychometrics of the SNAIS were estimated using appropriate statistical methods.
Two factors, Social Function Use Intensity (SFUI) and Entertainment Function Use Intensity (EFUI), were clearly identified by both exploratory and confirmatory factor analyses. No ceiling or floor effects were observed for the SNAIS and its two subscales. The SNAIS and its two subscales exhibited acceptable reliability (Cronbach's alpha = 0.89, 0.90 and 0.60, and test-retest Intra-class Correlation Coefficient = 0.85, 0.87 and 0.67 for Overall scale, SFUI and EFUI subscale, respectively, p<0.001). As expected, the SNAIS and its subscale scores were correlated significantly with emotional connection to social networking, social networking addiction, Internet addiction, and characteristics related to social networking use.
The SNAIS is an easily self-administered scale with good psychometric properties. It would facilitate more research in this field worldwide and specifically in the Chinese population.
•Mobile phone dependence (MPD), college adjustment (CA) and mental health status (MHS) were significantly correlated.•T1 MPD predicted poor T3 MHS.•T2 CA mediated the effect of T1 MPD on T3 MHS.
This ...3-year longitudinal study investigated the prospective relationships between mobile phone dependence and mental health status (i.e., subjective well-being, anxiety and depression) and the mediating role of college adjustment among Chinese undergraduate students.
The study recruited 265 first-year undergraduate students from a university (mean age = 18.95 years, SD = 0.72) in Wenzhou, China. A baseline survey and two follow-up surveys were conducted between November 2013 and December 2015 (the response rate was 76.4%). The validated Mobile Phone Addiction Tendency Scale (MPATS), Chinese College Student Adjustment Scale (CCSAS), Index of Well-being, Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS) were used for assessments.
The prevalence of anxiety and depression at Year 3 was 7.5% and 9.4%, respectively. Correlation analyses showed that mobile phone dependence at Year 1, college adjustment at Year 2, and mental health status at Year 3 were significantly correlated with each other. Structural equation modeling analyses showed that mobile phone dependence at Year 1 significantly predicted poor mental health status at Year 3. College adjustment at Year 2 significantly mediated the effect of mobile phone dependence at Year 1 on mental health status at Year 3.
Interventions both on reduction of mobile phone dependency and improvement of college adjustment (especially among those with mobile phone dependence) are possible and needed among new college students to prevent their future depression and anxiety. Such interventions should be incorporated into regular education programs in universities.
