This study investigated influence of parental support and monitoring on antisocial behaviour among Secondary School Students in Gwer West Local Government Area of Benue State. The recent hike in the rate of adolescent vices (rape, robbery, thuggery and examination malpractices) experienced in Nigerian society calls for the need for this study while examining the Parental roles. Ex-post facto design was utilized for the study. Purposive and simple random sampling technique was used to sample six secondary schools and 184 students comprising of 118 (64.1%) males and 66 (35.9%) females respectively. The Revised Child Report of Parent Behaviour Inventory, the Parental Monitoring Scale and the Bergen Questionnaire of Antisocial Behaviour were used for data collection. Three hypotheses were tested using simple linear regression and multiple regression. It was found among others that parental support has no significant influence on antisocial behaviour among secondary school students. The result also showed a significant influence of parental monitoring on antisocial behaviour among secondary school students and a significant joint influence of parental support and parental monitoring on antisocial behaviour among secondary schools students in Gwer-West Local Government Area of Benue State. Based on the study findings, recommendations were made.
