“…Due to the nature of these variables, they can be examined in light of the unified theory of development (Sameroff, 2010 ), which posits that human development is influenced by an array of interacting biological (e.g., neurophysiology, neuroendocrinology), psychological (e.g., social competence, identity), and social (e.g., family, school) factors. Even though adolescent impulsivity has a strong neurobiological component (Steinberg, 2008 ), the literature shows that lower levels of impulsivity/higher levels of self-control are predicted by: biological factors, namely the female gender (e.g., Perez et al, 2016 ) and older age groups (e.g., Inuggi et al, 2014 ); variables related to the family structure subsystem, including higher parental socioeconomic status (e.g., Assari et al, 2018 ); aspects related to the parent characteristics subsystem, namely higher parental self-control/lower parental impulsivity (e.g., Bolger et al, 2022 ); variables related to the peers and the community subsystems, such as positive school environment and positive peer relationships (e.g., Joo & Lee, 2020 ); and factors related to the family processes subsystem, including positive parenting (e.g., Khurana & Romer, 2020 ). Moreover, impulsivity has been found to be negatively correlated with: aspects related to the peers and the community subsystems, such as positive peer relationships (e.g., Moyano et al, 2022 ); variables related to the family processes subsystem, including early memories of warmth and safeness (Barreto Carvalho et al, 2015 ) and positive family relationships (e.g., Song et al, 2019 ); and psychological factors, such as rational decision-making style (Jelihovschi et al, 2018 ), resilience (Ran et al, 2022 ), problem-focused coping (Li et al, 2019 ), and emotion regulation (e.g., Hasking & Claes, 2020 ).…”
