COVID-19 has spread worldwide causing an unprecedented public health crisis. After the World Health Organization declared a pandemic in March 2020, the number of confirmed cases and deaths has continued to increase. This situation may be prolonged until an effective, tested, and safe treatment is available. COVID-19 can occur at any age. However, the maximum confirmed cases and deaths have occurred among the elderly. Particularly, the mental and physical health of the elderly aged above 60 and classified as high-risk groups is more vulnerable than other age groups, requiring more attention. Strong social restraint, social distancing, and quarantine measures to prevent the COVID-19 spread have raised concerns about their mental health. Therefore, it is crucial to analyze and identify the psychological concepts and protective factors that support and constitute these guidelines and strategies and prepare practical suggestions and guidelines to protect the mental health of the elderly during COVID-19. These discussions will facilitate a deeper understanding and expansion of these guidelines and strategies. Therefore, this study explores factors—including pandemic-induced stress, self-integration, self-efficacy, and resilience—in order to prepare practical and detailed suggestions and guidelines using studies that considered these factors, including coping with COVID-19-induced stress, social support, and physical activity.

The declining fertility rate and an aging population have accelerated the number of single-person households and nuclear families, and the number of households raising pets has naturally increased. However, pet owners experience great sorrow and trauma due to the death of their pets. The stronger the attachment to pets, the more severe the separation pain caused by pet loss. The purpose of this study was to analyze the moderating effect of a cognitive emotion regulation strategy mediated through separation pain on the relationship between attachment and post-traumatic growth after pet loss among owners. The study participants were 303 owners who have experienced pet loss. We analyzed the mediated moderating effects by PROCESS macro. The results showed that the adaptive cognitive emotion regulation strategy strengthened the effect of attachment to pets on post-traumatic growth and decreased the effect on separation pain. Conversely, the maladaptive cognitive emotion regulation strategy weakened the effect of attachment to pets on post-traumatic growth and strengthened the effect on separation pain. The act of intentionally expanding the perspective on pet loss experience, switching into a more positive focus, and accepting reality will reduce the grief of its companions and become an opportunity for growth.

Although the smoking rate among women has been continuously increasing recently, it is very difficult to explore the actual situation because of negative social views. This study aimed to analyze the effects of smoking awareness and living environment on the intention to quit smoking among female smokers. After receiving approval from the Research Ethics Committee in September 2021, secondary data analysis was performed for this study. A total of 378 working women who smoked were included in this study. The mean age was 34.4 years. The results showed that women living alone had significantly lower intentions to quit smoking, and women with experience in smoking cessation education had significantly higher intentions to quit smoking. In addition, it was found that the group having awareness of smoking cessation policy and smoking cessation treatment had high intention to quit smoking. As a result of the analysis of decision trees using data mining techniques, the strongest predictor of the intention of female workers who smoke to quit smoking was their perception of smoking cessation policies. In addition, it was found that the state’s policy support was important in that the group with the highest intention to quit smoking was the one with high awareness of both the smoking cessation policy and smoking cessation treatment. Finally, the risk group with the lowest intention to quit smoking was the group with low awareness of the anti-smoking policy, living alone, and having low awareness of the harmfulness of cigarettes. The importance of establishing policies for this vulnerable group, smoking cessation policies and treatment of female smokers, and improving awareness of the harmful effects of tobacco are discussed.

This study examined the differences in perceived stress, subjective well-being, psychosocial variables, and differences in parents’ parenting styles according to game use type among Korean adults. The study involved 300 participants in their 20s and 30s, a demographic typically associated with frequent gaming. Data were collected through an online survey company, and analyses were conducted using SPSS 25.0, including correlation, cluster, ANOVA, and correspondence analyses. The results showed that the general and adaptive game use groups had significantly lower levels of perceived stress than the maladaptive and risky game use groups. Additionally, the adaptive game use group exhibited significantly higher subjective well-being than the maladaptive game use group. In terms of psychosocial characteristics, except for the general game use group, none of the other groups considered online gaming as addictive. Parenting styles showed significant differences in relation to game use in adulthood. Notably, democratic parenting styles were associated with the general and adaptive game use groups, whereas neglectful parenting styles were linked to the risky game use group. These findings suggest that the risky game use group is as vulnerable to stress as the maladaptive game use group, emphasizing the need for targeted screening and social attention for the risky game use group.

With the rise of digital devices, gaming has become both a pastime and part of the culture for young people. Teenagers use games to communicate, enjoy leisure time, and relieve stress. However, the maladaptive use of gaming can lead to difficulties in adolescents’ daily lives and school adjustment. Increasing adolescents’ self-regulation competencies can improve maladaptive gaming behaviors and help them use gaming adaptively. Therefore, this study examined the moderating effect of self-regulation on the impact of adolescent gaming behavior on school adjustment. This study considered 359 adolescent participants in South Korea. Data were analyzed using hierarchical regression to test the moderating effect. The results indicated that adolescents’ adaptive use of games significantly increased school adjustment. Self-regulation significantly moderated the negative effects of the maladaptive use of games on school adjustment. Furthermore, the results revealed that the groups with highly adaptive and maladaptive use of games had high school adjustment but low self-regulation, indicating that they required active intervention.

As the coronavirus disease (COVID-19) pandemic ends, it is worth considering whether the ability to cope with such a pandemic has improved. The initial response to COVID-19 was hampered by the fear of new infectious diseases and spread of misinformation on the Internet. This highlights the need to enhance our ability to critically evaluate information rather than indiscriminately search for and trust information on the Internet. Therefore, this study examined how cyberchondria and eHealth literacy moderate the effect of fear of COVID-19 on the efficacy of coping behaviors for future epidemics and pandemics. The participants were 1000 adults in South Korea who were selected based on population proportionality. The results showed that fear of COVID-19 was significantly positively related to cyberchondria, and eHealth literacy was significantly positively related to the efficacy of coping behaviors. Further, the fear of COVID-19 had a significantly negative effect on the efficacy of coping behaviors, and the moderating effect of cyberchondria varied according to the level of eHealth literacy. These results emphasize the importance of eHealth literacy in enabling critical decision-making regarding misinformation.
