Socio-demographic and mental health correlates of internet addiction amongst Hong Kong university students under COVID-19.

Introduction: Regarding the problem of Internet addiction (IA) amongst university students under the pandemic, there are several research gaps. Firstly, few studies have examined IA of university students in Hong Kong, which is a Chinese society heavily influenced by Western values. In addition, findings on the socio-demographic correlates and psychological well-being predictors of IA in university students are unclear. Finally, researchers have not systematically examined the interaction effects of socio-demographic factors (particularly gender and personal infection of COVID-19) and psychological morbidity on IA. This pioneer study aimed to investigate the predictive role of socio-demographic factors and psychological morbidity in IA, and the moderating effects of gender and personal infection of COVID-19 on the relationship between psychological morbidity and IA. Methods: We conducted an online survey (N = 1,020 university students) during the ending phase of Wave 5 of the pandemic in Hong Kong (late 2022 to early 2023). Socio-demographic correlates included age, gender, living status, personal and family financial situation, student status, personal and family infection of COVID-19. Participants responded to validated measures of psychological morbidity, including depression, suicidal behavior, and hopelessness. Hierarchical regression and simple slope analyses were used to examine the predictive role of socio-demographic variables and psychological morbidity in IA and the interactive effect of gender and personal infection of COVID-19 with psychological morbidity on IA. Results: Personal financial difficulty was a significant socio-demographic predictor of IA. Depression, suicidal behavior, and hopelessness positively predicted IA. We also found a significant interaction effect of gender and psychological morbidity on IA. While the predictive relationship between depression and IA was stronger in males than in females, hopelessness was more strongly related to IA in females than in males. Finally, there was a significant interaction effect of personal infection of COVID-19 and suicidal behavior on IA. Conclusion: Personal financial difficulty was a socio-economic correlate of IA. Psychological morbidity also predicted IA. Gender and personal infection of COVID-19 moderated the linkage between psychological morbidity and IA. The findings of the study enhance our understanding of individual differences in IA in university students during the pandemic, particularly concerning different ecological risk factors.

Use of instructional videos in leadership education in higher education under COVID-19: A qualitative study.

The use of online teaching mode has grown rapidly in recent years, particularly under the COVID-19 pandemic. To promote the learning motivation of students and teaching effectiveness, development of attractive online teaching material such as videos is important. In the present study, we developed 15 theory-related videos and 9 case-based videos in the context of a leadership course focusing on psychological well-being and psychosocial competence. Using a qualitative research methodology via focus groups (N = 48 students) to evaluate these videos, six themes emerged from the data, including video arrangement, design of videos, content of videos, benefits to students' pre-lesson self-learning, benefits to students' learning of course content, and contribution to students' class participation. The findings suggest that the videos can elicit positive perceptions of the students in a flipped classroom arrangement. Students also benefit from the videos in terms of their understanding of course content and their participation in class discussion. Besides, the study suggests that the videos promote the learning efficiency of the students. The present qualitative findings concurred with the previous quantitative findings, suggesting the value of using virtual teaching and learning to promote psychosocial competence in university students.

Stress and depressive symptoms in university students in Hong Kong under the pandemic: Moderating effect of positive psychological attributes.

Introduction: There are very few studies examining the psychological well-being of university students in Hong Kong under the COVID-19 pandemic. Besides COVID-19-related stress, the "social event" in 2019-2020 has caused significant stress in young people. As such, we attempted to answer several research questions in this paper. First, what are the relationships between stresses (COVID-19 and "social event" related stresses) and psychological well-being indexed by depressive symptoms? Based on the stress and coping perspective, we predicted that there would be positive relationships between both types of stress and depression. Second, what are the relationships between different positive psychological factors (including life satisfaction, resilience and emotional management, flourishing, and beliefs about adversity) and depression? Based on different theoretical models of positive psychology, we hypothesized that negative relationships would exist between positive psychological factors and depressive symptoms. Third, do positive psychological attributes moderate the associations between stresses (COVID-19 and "social event" related stresses) and depressive symptoms? Based on the positive psychology literature, we hypothesized that positive psychological attributes would buffer the negative impact of stresses on depression. Methods: We recruited university students roughly one year after the first wave of the pandemic (N = 1,648) in early 2021. We used 25 items to measure COVID-19-related stress and "social event" related stress. For psychological well-being indexed by depressive symptoms, we used the "Centre for Epidemiologic Studies Depression Scale Revised (CESD-R)". For positive psychological attributes, we employed established measures of life satisfaction, resilience and emotional management, flourishing, and beliefs about adversity. Results: Regarding the relationship between stress and depression, we found positive relationships between both types of stress and depressive symptoms. As predicted, negative relationships existed between all positive psychological attributes and depressive symptoms. Besides, the positive psychological attributes significantly moderated the effects of stresses on depression, suggesting that these factors can reduce the negative impacts of stresses on depression. The present findings provide support for those models, highlighting the importance of positive psychological attributes as protective factors for university students' depression. Discussion: The findings of this study underscore the important role of positive psychological attributes in the stress-depression relationship in university students under the pandemic. The findings also generalize the positive youth development theory in the Chinese context. In terms of practice, university administrators and service providers should consider cultivating positive psychological attributes in university students with the purpose of promoting their psychological well-being.

Ecological predictors of academic satisfaction in senior secondary school students in Hong Kong: The mediating role of academic confidence.

Introduction: Although the secondary school curriculum reform has taken place for more than 1 decade in Hong Kong, very few studies have examined senior secondary school students' academic satisfaction and its predictors at the individual and school levels. The present study examined the influence of academic stress, school support, positive youth development (PYD) attributes on academic satisfaction via the mediation of academic confidence among senior secondary school students using three-wave longitudinal data. Methods: This study was derived from a 6-year longitudinal project examining youth development among Hong Kong adolescents. Only three waves of data collected from 2,023 students, including 959 boys (47.4%) and 1,040 girls (51.4%), from grade 10 to 12 (i.e., Waves 4-6), were used in the present study focusing on senior high school years. Students responded to a questionnaire concerning different aspects of their development, including their perceptions of school support, PYD attributes, academic stress, academic confidence, and satisfaction with the NSS curriculum. We conducted structural equation modeling (SEM) to test the hypothesized model. Results: Results showed that while Wave 4 academic stress negatively predicted academic satisfaction at Wave 6, Wave 4 positive youth development attributes and school support had positive associations with Wave 6 academic satisfaction; Wave 5 academic confidence also served as a mediator in these relationships, except for the relationship between school support and academic satisfaction. Discussion: The theoretical, practical, and policy implications of the findings are discussed. The present study generally supports previous findings on the relationships between academic stress, school support, PYD attributes, academic confidence, and academic satisfaction. The findings emphasize the prominence of PYD attributes, school support, and confidence in enhancing students' academic satisfaction.

Need Satisfaction and Depressive Symptoms Among University Students in Hong Kong During the COVID-19 Pandemic: Moderating Effects of Positive Youth Development Attributes.

As studies on the mental health status of university students during the COVID-19 pandemic are almost non-existent in Hong Kong, we examined four research questions in this paper: What is the prevalence of depressive symptoms in university students in Hong Kong? What are the socio-demographic correlates of depressive symptoms? Do need satisfaction and positive youth development (PYD) attributes, including beliefs about adversity, psychosocial competence (resilience and emotional competence) and family functioning predict depression? Do PYD attributes moderate the predictive effect of need satisfaction on depression? We examined the above research questions using the Centre for Epidemiologic Studies Depression Scale Revised (CESD-R) in 1,648 university students in Hong Kong. For PYD attributes, we utilized validated measures of Chinese beliefs about adversity, psychosocial competence (resilience and emotional competence), and family functioning. For need satisfaction, we used a measure derived from two focus group interviews involving university students. Results showed that 48.4% of the respondents (95% confidence interval = [45.9%, 51.1%]) scored 16 or above (i.e., "at-risk" for clinical depression). As predicted, age, gender, student status (local vs. international), and family financial hardship were significant socio-demographic correlates of depressive symptoms. Besides, need satisfaction and PYD attributes negatively predicted depression scores. Finally, multiple regression analyses controlling for gender, age, and student status as covariates showed that all PYD attributes moderated the impact of need satisfaction on depression. The findings reinforce the theoretical proposition that PYD attributes serve as important factors in protecting the mental health of university students during the pandemic.

Subjective Outcome Evaluation of Instructional Videos in Leadership Education.

The aims of this study were to examine the psychometric properties of two subjective outcome evaluation tools measuring students' perceptions of 24 instructional videos and to understand the profiles of students' perceptions of the videos. Online teaching and learning played an important role when school lockdown measures were imposed during the COVID-19 pandemic. To facilitate online teaching in a college-level leadership education subject, we developed and piloted 24 instructional videos, including 15 animated videos and 9 case-based videos, in the 2021/22 academic year. To understand students' perceptions of the videos, we developed two subjective outcome evaluation scales (one for the animated videos and another for the case-based videos) to assess the subjective perceptions of 1308 students. Results showed that the developed tools possessed good psychometric properties, including factorial, convergent and discriminant validity. The findings of this study also revealed the students had positive attitudes towards the developed videos, including positive perceptions of the videos' design and the benefits gained from watching them. The present study suggests teachers can meaningfully use the 24 instructional videos in the context of leadership education in higher education.

Matrix-assisted laser desorption ionisation-time of flight mass spectrometry for rapid identification of Laribacter hongkongensis.

Laribacter hongkongensis is a Gram-negative, facultative anaerobic, motile, S-shaped, urease-positive bacillus associated with invasive infections in liver cirrhosis patients and community-acquired gastroenteritis. Most cases of L hongkongensis infections occur in eastern countries. Information is lacking on the usefulness of matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) for the identification of bacteria important in eastern countries. Using the Bruker database extended with 21 L hongkongensis reference strains, all 240 L hongkongensis isolates recovered from patients, fish, frogs and water were correctly identified, with 224 (93.3%) strains having top match scores ≥2.0. Notably, the strain of Chromobacterium violaceum was not reliably identified although it is included in the database. MALDI-TOF MS is useful for the accurate routine identification of L hongkongensis after adding reference L hongkongensis main spectra to the database. The number of strains for each species in MALDI-TOF MS databases should be expanded to cover intraspecies variability.
