The present study examines the relationship between parental involvement and impulsiveness of high school students. Adolescence is a developmental stage marked by heightened emotional reactivity and susceptibility to impulsive behaviors, making parental involvement a crucial factor in promoting selfregulation and positive behavioral outcomes. The objective of the study is to determine whether a significant correlation exists between parental involvement and impulsiveness in adolescents. A descriptive survey method was employed, and data were collected from a randomly selected sample of 100 high school students using the Parental Involvement Scale by Chouhan and Arora (2009) and the Impulsiveness Scale by Rai and Sharma (2013). Statistical analysis included measures of central tendency, variability, and Pearson’s correlation. Results indicated a significant negative correlation between parental involvement and impulsiveness demonstrating that higher levels of parental involvement are associated with lower impulsive behaviour. These findings highlight the importance of parental engagement in shaping adolescents’ emotional regulation, academic behaviour, and overall developmental outcomes, particularly during a sensitive stage of psychological growth. The study underscores the need for school-based and community-based initiatives that strengthen parent– adolescent relationships to foster healthier behavioural patterns during the high school years.
