- The safe, highly effective measles vaccine has been recommended globally since 1974, yet in 2017 there were more than 17 million cases of measles and 83,400 deaths in children under 5 years old, and more than 99% of both occurred in low- and middle-income countries (LMICs)1–4. Globally comparable, annual, local estimates of routine first-dose measles-containing vaccine (MCV1) coverage are critical for understanding geographically precise immunity patterns, progress towards the targets of the Global Vaccine Action Plan (GVAP), and high-risk areas amid disruptions to vaccination programmes caused by coronavirus disease 2019 (COVID-19)5–8. Here we generated annual estimates of routine childhood MCV1 coverage at 5 × 5-km2pixel and second administrative levels from 2000 to 2019 in 101 LMICs, quantified geographical inequality and assessed vaccination status by geographical remoteness. After widespread MCV1 gains from 2000 to 2010, coverage regressed in more than half of the districts between 2010 and 2019, leaving many LMICs far from the GVAP goal of 80% coverage in all districts by 2019. MCV1 coverage was lower in rural than in urban locations, although a larger proportion of unvaccinated children overall lived in urban locations; strategies to provide essential vaccination services should address both geographical contexts. These results provide a tool for decision-makers to strengthen routine MCV1 immunization programmes and provide equitable disease protection for all children.

- A healthy lifestyle with sufficient physical activity (PA) can contribute to weight management. Yet, many people do not maintain a healthy lifestyle. To explain PA, we propose a model that incorporates the Theory of Planned Behavior (TPB) with weight-related self-stigma. We recruited 325 young adults to complete questionnaires regarding their physical activities, weight-related self-stigma, and TPB factors. We used structural equation modeling to examine the model fit and the path invariance across weight groups. The model showed excellent model fit, but path invariance was not supported. Weight-related self-stigma significantly explained the perceived behavioral control, behavioral intention, and engagement of PA. People without overweight and people with overweight have different considerations for PA. Weight-related self-stigma is important for PA as well. To promote a healthy lifestyle, healthcare providers should provide different suggestions or interventions that suit their patients' weight-related concerns.

- Background: Binge-watching, the viewing of online videos or streamed content, may be associated with different types of mental health problems. The present study aimed to investigate the associations between binge-watching and five mental health concerns including depression, loneliness, sleep problems, anxiety, and stress. Methods: Academic databases of PubMed, Scopus, Web of Science, ProQuest, PsycINFO, and Psych Articles were systematically searched through February of 2022. The Newcastle-Ottawa Scale was used to assess the methodological quality. A meta-analysis was performed on Fisher's z values as effect sizes, using a random effect model. Publication bias, small study effect, and moderators in this association were assessed. Results: Binge-watching was significantly associated with the five types of mental health concerns with the most robust correlations found with stress (0.32) and anxiety (0.25). Stronger associations between binge-watching and two types of mental health problems (depression and sleep problems) were found during the COVID-19 pandemic than before the pandemic. Moreover, stronger associations between binge-watching and two types of mental health problems (stress and sleep problems) were found in developing countries than in developed countries. Conclusions: The associations between binge-watching and mental health concerns were significant and positive. Programs and interventions to reduce binge-watching should be considered and tested.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The percentage of individuals who were fully vaccinated against COVID-19 was 53% worldwide, 62% in Asia, and 11% in Africa at the time of writing (February 9, 2022). In addition to administrative issues, vaccine hesitancy is an important factor contributing to the relatively low rate of vaccination. The Motors of COVID-19 Vaccination Acceptance Scale (MoVac-COVID19S) was developed to assess COVID-19 vaccination acceptance levels. However, it has only been tested among Taiwanese, mainland Chinese, and Ghanaian populations (Chen et al, 2021; Fan et al, 2021; Yeh et al, 2021). Therefore, the present study examined the construct validity and measurement invariance of the MoVac-COVID19S among individuals from five countries (ie, Taiwan, mainland China, India, Ghana, and Afghanistan). Participants and Methods: A cross-sectional survey study recruited 6053 participants across five countries who completed the survey between January and March 2021. Confirmatory factor analysis (CFA) fit indices were used to examine factor structure and measurement invariance across the five countries. Results: The fit indices of the CFA were relatively good across the countries except for the root mean square error of approximation (RMSEA). Moreover, the four-factor structure (either nine or 12 items) had a better fit than the one-factor structure. However, the four-factor model using nine MoVac-COVID19S items was the only model that had measurement invariance support for both factor loadings and item intercepts across the five countries. Conclusion: The present study confirmed that the MoVac-COVID19S has acceptable psychometric properties and can be used to assess an individual's willingness to get COVID-19 vaccination.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Aside from personal beliefs, young adults’ intention to uptake the COVID-19 vaccine can be influenced by their fear of COVID-19 and perceived infectability of COVID-19. The present study incorporated fear of COVID-19 and perceived infectability with the theory of planned behavior (TPB) to form an expanded TPB to analyze factors affecting Pakistani young adults’ intentions to uptake the COVID-vaccine in Pakistan.Methods: A cross-sectional study was conducted and recruited participants from Pakistani social media users. The proposed extended TPB model was examined by using structural equation modeling.Results: A total of 1034 individuals replied to the survey. The three factors of the original theory of planned behavior and the fear of COVID-19 were positively related to their intention to uptake COVID-19 vaccination (r = 0.25-0.66). Moreover, the perceived infectability positively influenced the three theories of planned behavioral factors and the fear of COVID-19 (r = 0.27-0.60), also affecting the participants’ intentions to uptake COVID-19 vaccination.Conclusions: Perceived infectability was positively related to the participants’ intentions to uptake COVID-19 vaccination, and perceived behavioral control was the strongest mediator. More evidence-based information concerning treatments and COVID-19 vaccination are needed to encourage individuals to uptake the vaccine.

- The combination of inadequate health systems and the occurrence of humanitarian crisis results in significant logistics and supply chain management (LSCM) challenges in the support of their vulnerable populations. Because of the high cost of humanitarian LSCM and the limited funding available, it is important that organizations make the most of their limited resources. The aim of this research is to develop our understanding of the drivers of LSCM cost in a humanitarian setting. The paper explores the importance of a range of different underpinning potential factors impacting the cost per beneficiary and develops a resultant set of hypotheses tested with a robust regression model. The results demonstrate that the number of beneficiaries and the type of organization, the country’s gross domestic product (GDP) per capita, and the type of health programme all affect the supply chain costs per beneficiary. This research helps further the understanding of the drivers of efficiency for humanitarian supply chains and the impact of health programme design on supply chain costs.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: The nine-item Internet Gaming Disorder Scale -Short Form (IGDS-SF9) is brief and effective to evaluate Internet Gaming Disorder (IGD) severity. Although its scores show promising psychometric properties, less is known about whether different groups of gamers interpret the items similarly. This study aimed to verify the construct validity of the Persian IGDS-SF9 and examine the scores in relation to gender and hours spent online gaming among 2,363 Iranian adolescents. Methods: Confirmatory factor analysis (CFA) and Rasch analysis were used to examine the construct validity of the IGDS-SF9. The effects of gender and time spent online gaming per week were investigated by multigroup CFA and Rasch differential item functioning (DIF). Results: The unidimensionality of the IGDS-SF9 was supported in both CFA and Rasch. However, Item 4 (fail to control or cease gaming activities) displayed DIF (DIF contrast = 0.55) slightly over the recommended cutoff in Rasch but was invariant in multigroup CFA across gender. Items 4 (DIF contrast = -0.67) and 9 (jeopardize or lose an important thing because of gaming activity; DIF contrast = 0.61) displayed DIF in Rasch and were non-invariant in multigroup CFA across time spent online gaming. Conclusions: Given the Persian IGDS-SF9 was unidimensional, it is concluded that the instrument can be used to assess IGD severity. However, users of the instrument are cautioned concerning the comparisons of the sum scores of the IGDS-SF9 across gender and across adolescents spending different amounts of time online gaming.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To translate and cross-culturally adapt the Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A) for use in Taiwan and to validate their internal consistency, construct validity, measurement invariance, and convergent validity in Taiwanese young adults.Methods: The GDT and GADIS-A were translated into traditional (unsimplified) Chinese characters and culturally adapted according to standard guidelines. A sample of 608 Taiwanese university students were recruited online. All participants completed the GDT, GADIS-A, Internet Gaming Disorder Scale – Short Form (IGDS9-SF), and Depression Anxiety Stress Scale-21 (DASS-21). Internal consistency was assessed using Cronbach's α and McDonald's ω. Factor structure was examined using Confirmatory Factor Analysis (CFA). Measurement invariance in gender was assessed by three nested models in CFA. Convergent validity was determined by calculating Pearson's r among the GDT, GADIS-A, IGDS9-SF, and DASS-21.Results: The GDT and GADIS-A showed adequate internal consistency (both α and ω = 0.90). The CFA results supported a one-factor structure for the GDT and a two-factor structure for the GADIS-A. Measurement invariance across gender was supported for both the GDT and GADIS-A. The convergent validity of the GDT and GADIS-A were acceptable.Conclusions: The Chinese versions of the GDT and GADIS-A are valid and reliable tools that can be used to assess gaming disorder in Taiwanese young adults. Measurement invariance across genders was supported for both tools. The convergent validity of the GDT and GADIS-A were also satisfactory.

- AIM: To explore the perspectives of preceptors about clinical assessment for undergraduate nursing students in transition to practice.BACKGROUND: The assessment of clinical competence is a complex process due to the diverse nature of nursing practice. As such, nurse preceptors play a crucial role in clinical assessment for nursing students. Although preceptors may enjoy the process of clinical teaching and assessment, they face challenges that need to be addressed to facilitate students' clinical learning and assessment.METHODS: An exploratory qualitative approach was adopted. A purposive sample of 17 preceptors from two tertiary hospitals in Singapore was recruited to participate in three focus group discussions from March to July 2014.FINDINGS: Five themes emerged from the data analysis: the need for a valid and reliable clinical assessment tool; meaningful reflection and feedback; varied methods in clinical assessment; high level of commitment and struggles with dual roles and the need to enhance the support system for preceptors.CONCLUSIONS: There is no doubt that a valid and reliable clinical assessment tool can serve as a guide for preceptors to enhance their clarity in assessment and feedback. It is essential for all stakeholders to be involved in the development of the clinical assessment tool. Workload, time, support system and formal educational programmes for preceptors influenced their preparation and self-confidence.IMPLICATIONS FOR NURSING AND/OR HEALTH POLICY: The themes that emerged from the focus group discussions could assist in the development of a more reliable and valid clinical assessment tool to evaluate the clinical competence of nursing students in transition to practice. Clinical and educational institutions could collaborate closely to develop an educational programme and a preceptorship handbook, focusing on pedagogical contents for clinical education and assessment.
