Adolescents' Mental Well-Being and Social Support: Mixed Methods Study.

Adolescents are vulnerable to developing mental health problems and mental health disorders if untreated. Various factors can influence their mental well-being, including personal, interpersonal, community and environmental factors. Interpersonal relations with family and friends may have an influence on the vulnerability of adolescents to developing mental health problems. The aim of this paper is to determine adolescents' mental well-being and the correlation between adolescents' mental well-being and the support of family, friends, teachers, and registered nurses. We performed a mixed-methods study. The survey method was used to collect the data among adolescents, and semi-structured interviews were conducted among adolescents, parents, teachers, decision makers, and registered nurses. A total of 2972 adolescents participated in the quantitative part of the study. The mental well-being of adolescents is positively correlated (r = 0.624) with their social support, while their mental well-being (r = -0.286) and social support (r = -0.239) decline with age. Furthermore, the perceived level of support from registered nurses did not differ significantly by age (r(2965) = -0.004, p = 0.863) or gender (W = 310 616, p = 0.903). Qualitative findings further emphasised that adolescents perceive registered nurses as important sources of advice, guidance, and emotional support, underscoring the nursing contribution to adolescent mental health promotion. The mental well-being of adolescents is related to their interactions and interpersonal relations with parents, friends, and teachers. In ensuring the mental well-being of adolescents, we must consider the multidimensional model of well-being. Adolescents' mental well-being declines with age and is higher among adolescents who receive more social support. Therefore, future interventions and actions should focus on social support and interdisciplinary work.
