Even though boys’ depression has become important, and their smartphone use has increased since COVID-19, little is known about low-income middle and high school boys’ depression in the context of whether they have siblings. Thus, this study investigates the relationship between smartphone addiction and depression as well as the moderating effect of being an only child on the relationship. Participants were limited to middle and high school students whose families were regarded as having a low-income. A total of 129 low-income boys were selected for the final sample. The PROCESS macro 3.4 for Statistical Product and Service Solutions was used to identify the moderating effect. Smartphone addiction was positively related to depression among low-income male students. Being an only child significantly moderated the relationship between smartphone addiction and depression. This study contributes to understanding the importance of examining mental health problems among middle school boys since COVID-19, particularly among low-income boys. It is necessary to provide tailored mental health services for middle school boys in low-income families. Alternative activities and social programs should be provided for adolescent boys who are only children to safely socialize with friends and peers without a smartphone.

This study examines the moderating effect of a mentorship program on the relationship between parental neglect and depression among adolescents from low-income households since COVID-19. A total of 264 participants from all provinces in South Korea were registered for a mentorship program provided by the Korea Development Bank [KDB] Foundation, which is a charitable and non-profit organization. Two-hundred fifty-five middle and high school students from low-income families were included in the final sample. The mentorship program was provided to students based on mentors’ advice and feedback. A bootstrap method using the PROCESS macro 3.4 for SPSS was utilized to examine the moderating effect of satisfaction with the mentorship program. Neglect was positively related to depression among low-income students. Satisfaction with the mentorship program moderated the relationship between low-income students’ neglect and depression. Visits from social workers or other advocates or volunteers to low-income families with children may be helpful to address depression among low-income students. High quality mentorship programs should be provided to more low-income students for their mental health, funded particularly in the context of corporate social responsibility. Particularly since the COVID-19 pandemic, financial contributions by corporations would be valuable to reconstruct the damage to quality of life and psychological well-being among low-income adolescents.

Purposes: This study investigates the moderating effect of age on the association between relationship with mentors and self-efficacy among low-income students. Methods: A total of 255 low-income middle and high school students participated. The PROCESS macro 3.4 for Statistical Product and Service Solutions was employed to test the moderating effect. Results: Quality of relationship between mentors and mentees was positively associated with mentees' self-efficacy. Students' age significantly moderated the association between quality of the relationship with mentors and self-efficacy. Discussion: It is important to expand mentorship programs for low-income students during the COVID-19 pandemic in order to foster high self-efficacy among adolescents. Recruitment of high quality mentors and additional factors that may be helpful to a good relationship between mentees and mentors, such as mentor training, mentor screening, and mentor-mentee matching, should be prioritized to improve self-efficacy among low-income students since COVID-19. Early opportunities for mentoring from high quality mentors is particularly important to increase self-efficacy among younger students such as middle school students.
