"THE EVOLVING SPECTRUM OF BEHAVIOURAL PROBLEMS IN ADOLESCENTS: AN ANALYTICAL STUDY OF DEVELOPMENTAL, EMOTIONAL, AND ENVIRONMENTAL DETERMINANTS AND INTERVENTION PATHWAYS"

Abstract

Adolescence is a critical developmental phase marked by rapid biological maturation, cognitive restructuring, emotional intensification, and expanding social interactions. While these transitions are essential for growth and identity formation, they also render adolescents particularly vulnerable to a wide spectrum of behavioural problems. Such problems—ranging from aggression, impulsivity, and defiance to withdrawal, rule-breaking, and academic disengagement—often emerge from the complex interplay of developmental, emotional, and environmental factors. The evolving nature of adolescent behaviour underscores the need for a multidimensional understanding that goes beyond viewing behavioural problems as isolated or purely pathological phenomena. For empirical implementation, the present study adopts a school-based, cross-sectional research design utilizing a defined adolescent cohort. The sample comprises 150 students of Class XII (Grades 12), aged 16–18 years, drawn from a co-educational senior secondary school located in Delhi (NCT). Late adolescence has been purposively selected as it represents a developmental phase characterized by heightened cognitive demands, increased autonomy, and intensified academic and psychosocial stressors, all of which are empirically linked to the manifestation of behavioural problems. The selection of a single institutional setting ensures environmental homogeneity, thereby minimizing extraneous variability related to school climate, academic structure, and disciplinary practices.

The sample is selected using a purposive sampling technique, guided by predefined inclusion criteria, namely enrollment in Class XII, regular school attendance, and willingness to participate in the study. Students with identified severe psychiatric or neurological conditions requiring clinical intervention are excluded to maintain focus on behavioural problems within the non-clinical school population. This sampling approach facilitates targeted examination of behavioural patterns within a developmentally and academically comparable group, enhancing internal validity while maintaining contextual relevance.

Data collection is conducted within the school premises under standardized conditions to ensure procedural consistency. The chosen sample size of 150 participants is considered adequate for descriptive and inferential analysis of behavioural dimensions, allowing for meaningful interpretation of trends and associations within the defined cohort. By situating the investigation within a real-world educational context, the study strengthens its ecological validity and provides empirically grounded insights into the developmental, emotional, and environmental determinants of behavioural problems among adolescents in an urban school setting.
