TL;DR
This study validates a new inventory for measuring self-regulation of socioemotional behavior in adolescents, showing it is reliable and influenced by both genetics and environment.
Contribution
The study introduces a validated multidimensional inventory for self-regulation of socioemotional behavior with genetic and environmental insights.
Findings
The inventory's structure shows a bipolar factor representing vulnerability to psychopathology versus self-regulation capacity.
Self-ratings on the inventory correlate highly with co-twin ratings at age 17 and with earlier ratings at age 14.
Both genetic and environmental factors contribute to individual differences in self-regulation.
Abstract
Instruments for rating socioemotional behavior with a strong theoretical basis, broad coverage of behaviors, and adequate validation are rare. Here, the Multidimensional Peer Nomination Inventory (MPNI) Form SERI (Socio(E]motional Regulation Inventory) was employed in a longitudinal population-based sample of Finnish twins at age 17 to study: (1) the structure of self-ratings on self-regulation of socioemotional behavior, (2) construct, criterion, concurrent, and predictive validity of the scales, as well as invariance analysis, and (3) genetic and environmental factors contributing to individual differences in self-regulation. A bipolar factor for low versus high self-regulation was interpreted as representing vulnerability to a p-factor (general psychopathology) versus src-factor (self-regulation capacity), and respective scales were formed for both. Behavioral regulation in each was…
