RT journal article T1 Overcoming barriers: a grounded theory of the experience of professionals working with justice-involved adolescents who use substances A1 Herrera-Sánchez, Isabel M. A1 Rueda-Méndez, Samuel A1 Luque Ribelles, Violeta A2 Psicología K1 psychoactive substance K1 Adolescents AB Adolescents involved in the juvenile justice system are particularly vulnerable to the effects ofpsychoactive substance use. Various studies have explored interventions from the perspectiveof professionals who seek strategies to meet their specific needs. This study aims todevelop a substantive theory based on the experiences of professionals working in outpatienttreatment centres, using a convenience sample of 20 interdisciplinary professionals. Semistructuredinterviews were conducted and analysed according to Grounded Theory, identifyinga basic social psychological process termed ‘overcoming barriers’, which includes fourcategories: reflectivity, identifying emotions, influence, and redefining results. Additionally, abasic social structural process was identified, consisting of six categories: succession, normalization,diversification, interrelation, openness, and adaptation. Three stages wereestablished to describe the sequence in which these processes progress. The discussionfocuses on analysing substance use from an ecological perspective, considering the diversityof profiles of justice-involved adolescents and best practices in professional decision-making.
