Dermatoglyphic Markers in Forensic Science: A Bio-Psychosocial Study of Juvenile Delinquency and Behavioral Traits

Abstract

Juvenile delinquency represents a significant socio-legal and psychological challenge, particularly in developing nations such as India.
Dermatoglyphics, the scientific study of fingerprint ridge patterns, is grounded in the premise that fingerprint formation occurs concurrently
with neurodevelopment during fetal life and remains unchanged thereafter. The present study investigates the relationship between
dermatoglyphic patterns, psychological attributes (self-efficacy and resilience), and socio-environmental factors influencing juvenile
delinquent behavior. Using a bio-psychosocial framework, the study integrates biological, psychological, and environmental dimensions.The
study adopted a descriptive–correlational research design to examine the relationship between dermatoglyphic patterns, psychological
characteristics, and juvenile delinquent behavior. A mixed-method design was adopted with a sample of 100 juveniles aged 10–18 years.
Dermatoglyphic analysis was conducted using the Ten-Digit Classification System, while psychological attributes were measured through
standardized scales. Socio-economic and environmental data were collected via structured interviews.Findings reveal that loop patterns were
predominant (60%), followed by whorls (30%). Significant associations were found between fingerprint patterns and crime types (χ² = 31.1, p
< .05). Psychological assessment indicated varied levels of self-efficacy and resilience, with higher resilience linked to better adaptive
outcomes. Socio-economic adversity, family disruption, and peer influence emerged as key environmental contributors.The study concludes
that dermatoglyphics, when ethically integrated with psychological assessment, can function as a supportive early-identification and preventive
tool, rather than a deterministic or punitive measure. The outcomes support a rehabilitative and preventive approach aligned with the objectives
of the Juvenile Justice system, emphasizing early intervention, counseling, and individualized rehabilitation strategies for at-risk youth.
