The increase in cyberbullying among adolescents poses a challenge for mental health professionals. One contributing factor is the lack of a clear and consistent def inition of self-control in digital interactions, leading to variability in prevention and intervention strategies in nursing care. This concept analysis aimed to clarify the concept of self-control in the context of adolescents’ experiences with cyberbullying. The concept analysis method developed by Walker and Avant was employed. A comprehensive literature search was conducted in PubMed, ProQuest, ScienceDirect, Scopus, and Google Scholar for articles published between 2010 and 2024. The results revealed that the def ining attributes of self-control include self-regulation, impulse control, delayed gratif ication to achieve goal orientation, responsible decision-making, and self-care capacity. Antecedents comprise emotional intelligence, motivation for positive behaviour, empathy, awareness of digital ethics, understanding of cyberbullying’s impact, and social support. The consequences include improved problem-solving skills, better social relationships, enhanced mental health, increased self-conf idence, and a higher quality of life. In conclusion, understanding the attributes, antecedents, and consequences of self-control provides a transparent framework for designing preventive strategies against cyberbullying. This conceptual clarity can be applied in nursing practice, particularly in psychosocial care programs that empower adolescents to navigate digital environments with resilience and responsibility. © 2026, Thailand Nursing and Midwifery Council.
