The Integrative Influence of Behavioral Genetics on Psychological Development: A Multidimensional Analysis of MPQ, PRISM, and ASSM Frameworks

Abstract Behavioral genetics provides a critical foundation for understanding how genetic factors interact with environmental influences to shape enduring personality traits. Within this framework, the Multidimensional Personality Questionnaire (MPQ) serves as a comprehensive psychometric instrument for evaluating key personality dimensions—Positive Emotionality (PEM), Negative Emotionality (NEM), and Constraint (CON)—which reflect the interplay of heritable predispositions and adaptive behavioral processes. Twin and family studies indicate moderate to high heritability for these core traits, underscoring the significant genetic basis for emotional reactivity, motivation, and self-regulation. To explore these relationships, Personality and Role Identity Structural Modeling (PRISM) and Advanced Statistical and Structural Modeling (ASSM) approaches were applied to examine the structural organization and interconnections among MPQ dimensions. These analytical frameworks revealed that the genetic and environmental integration of PEM and CON forms a stable foundation for emotional regulation, persistence, and adaptive control. The application of ASSM further established a hierarchical model accounting for significant variance in emotional and behavioral outcomes, confirming satisfactory model fit and internal consistency. In conclusion, integrating behavioral genetics with PRISM and ASSM modeling enhances the understanding of personality as a biologically grounded yet dynamically modulated system.
