Counselling Strategies for Managing Adolescent Delinquency in Secondary Schools in Delta State

This study examines the effectiveness of selected counselling strategies in managing adolescent delinquency among secondary school students in Delta State, South South Nigeria. Adolescent delinquency, including truancy, aggression, theft, and gang affiliation, has escalated in many Nigerian secondary schools, straining school management resources and undermining the academic environment. This research employed a quasi-experimental design in which three counselling approaches, namely Cognitive Behavioural Therapy, Reality Therapy, and Group Counselling, were each applied to separate groups of identified delinquent students across nine schools in Warri, Asaba, and Agbor over a 12-week period. A control group received no structured intervention. Delinquency frequency, assessed through school discipline records and the Jesness Behaviour Checklist, served as the primary outcome measure. Results indicate that all three counselling approaches significantly reduced delinquent behaviour frequency compared to the control group, with Cognitive Behavioural Therapy showing the largest effect size. Group counselling demonstrated particular effectiveness in improving peer relationship quality and reducing gang-related activities. Trained school counsellors delivered the interventions, and fidelity monitoring ensured programme integrity. The study recommends that secondary schools in Delta State deploy qualified counsellors trained in evidence-based approaches and develop school-wide behaviour management policies that complement individual-level interventions.
