The COVID-19 pandemic has highlighted the implementation of the Fourth Industrial Revolution (4IR), especially in the educational system, in which online learning can also be used as online training among school students. Interestingly, prior studies have highlighted trainers’ role as the most important factor affecting online training. However, prior studies that reported the effectiveness of online training among school students and the right trainers’ characteristics to sustain its effectiveness have been very limited. Therefore, the objective of this study was to determine online training effectiveness among 150 students in a Malaysian high school using pre-experimental research. Trainers’ characteristics perceived by participants were also determined and compared between classroom and online training. Findings indicated that online training was significantly effective regardless of gender and race differences; trainers’ characteristics explained 40.5% of variance in online training effectiveness. However, the school students preferred classroom training compared to online training; trainers’ characteristics were better in classroom training. Hence, it can be concluded that online training among school students can be effective; however, the characteristics of trainers can be improved to sustain the effectiveness of online training. These results have implications for the sustainability of effective 4IR in the educational system for the post-pandemic era.

Background Previous studies have cautioned about the negative impact of social media use on the mental health of adolescents and emerging adults. In 2021, the National Institutes of Health Malaysia emphasized the urgent need to address digital-related mental health issues, which pose a significant gap in our understanding. Nevertheless, there has been a lack of research on the effects of social media addiction on the mental well-being of local adolescents. This study aims to examine the effect of social media use on mental health issues among adolescents in Kelantan, Malaysia. Methods A total of 384 respondents voluntarily participated in this cross-sectional study involving ten districts in Kelantan using the snowball sampling method. Results Analysed data finds social media addiction correlates significantly with depression, suicide ideation and self-esteem. Multiple regression analysis indicated that suicide ideation was predicted by social media addiction and depression but not self-esteem. Furthermore, social media moderates the relationship between depression and suicidal ideation. Conclusion Controlling social media use may prevent addiction and promote greater mental health among adolescents.

Amidst the COVID-19 pandemic, mental health challenges have emerged, highlighting the need to identify psychological distress and coping strategies, particularly among occupational safety and health (OSH) competent persons. This is a cross-sectional study measuring stress, anxiety, and depression levels while exploring coping mechanisms among OSH professionals in Malaysia during the COVID-19 recovery phase, using DASS-21 and Brief-COPE questionnaires. The findings indicate that chronic illness increases the risk of depression (p=0.005) and stress (p=0.047). Higher income is associated with greater risks of depression (p<0.001) and stress (p<0.001). Monthly expenses exceeding budget limits heighten the risk of depression (p<0.001) and anxiety (p=0.024). Conversely, older age decreases the risk of both depression (p<0.001) and stress (p=0.001). Caring for family members affected by COVID-19 reduces depression (p<0.001) and stress (p<0.001). Having more monthly savings decreases the risk of depression (p<0.001) and anxiety (p=0.017). The study reveals that stress individuals prefer emotional focus coping (p=0.006). Addressing these factors is crucial for mitigating psychological distress among OSH professionals.
