Secondary school students often exhibit maladaptive behaviours that disrupt academic performance and social development, including bullying, truancy, anxiety, aggression, cultism, substance abuse, and other forms of misconduct. Factors such as overprotective parenting, where parents excuse or cover up children’s wrongdoings, can further exacerbate these behaviours. Maladaptive behaviour is broadly defined as any action that violates societal norms, school regulations, or ethical standards, and it may manifest as antisocial, criminal, or unethical conduct. While schools provide formal academic instruction, the development of socially acceptable behaviours and character formation largely depends on familial and community influence. This study examines the prevalence, causes, and impacts of maladaptive behaviours among secondary school students, emphasizing the need for effective interventions by educators, counsellors, and parents. By understanding the multifaceted nature of maladaptive behaviours, stakeholders can implement strategies to promote responsible behaviour, enhance student performance, and foster holistic development within the school environment.
