Purpose: This qualitative research was conducted to explore the experiences of social workers encountering peer conflicts among abused boys living in child counseling protection center (center) and psychosocially intervening to resolve peer conflicts. Methods: The participants were four social workers who were caring for twenty abused boys at the center. Data were collected through participatory observation, in-depth interview, and field data. The collected data were analyzed by emic coding. Results: First, the experiences of social workers encountering peer conflict phenomena among abused boys were ‘psychological distortion from abuse trauma’, ‘manifestation of impulse or aggression to trivial stimuli’, and ‘lack of mutual respect among peers’. Second, the experiences of social workers intervening in resolving peer conflicts among abused boys were ‘stabilize offended feeling’, ‘maintain stability through verbal and non-verbal interventions’, ‘apply positive techniques to improve peer relations’, and ‘help abused children overcome trauma and grow’. Conclusion: Social workers confirmed that the role of social welfare experts was important to secure understanding and insight into peer conflicts between abused children and to convert the pain of abused children into positive energy. The results of this study will help social welfare professionals develop a family-centered abuse trauma recovery program for abused children.
