Abstract
Effortful control (EC) plays a crucial role in psychopathology disorders. Emerging studies have paid attention to the effects of G × E interaction on EC. The present study investigated interactions between monoamine oxidase A (MAOA) T941G polymorphism with parenting practices on EC in a sample of 1,531 Chinese adolescents. The adolescents completed the Early Adolescent Temperament Questionnaire–Revised (EATQ–R) EC scale and the Parenting Style Index provided during the study to assess EC and parenting practices, respectively. MAOA T941G polymorphism exerted no effect on adolescent EC; however, results revealed that the MAOA gene interacted with parental acceptance/involvement in their associations with EC among boys. Specifically, although increased levels of parental acceptance/involvement benefited all adolescents, boys with G alleles of the MAOA gene exhibited higher sensitivity to parental acceptance/involvement, compared with T carriers; this interaction was not significant among girls. This study is the first to identify MAOA × parenting interaction on adolescent EC, further contributing to the literature in MAOA gene–EC.
Highlights
Effortful control, the self-regulatory aspect of temperament, is defined as the ability to inhibit a dominant response to perform a subdominant response, detect errors, and engage in planning (Ellis and Rothbart, 2001; Eisenberger et al, 2005; Rothbart and Bates, 2006)

All parenting practices showed significant positive correlation with EC; MAOA T941G polymorphism was not associated with EC in adolescents
Summary
The self-regulatory aspect of temperament, is defined as the ability to inhibit a dominant response to perform a subdominant response, detect errors, and engage in planning (Ellis and Rothbart, 2001; Eisenberger et al, 2005; Rothbart and Bates, 2006). This ability is associated with emotional and behavioral regulation and includes effortful modulation of attention (focusing and directing attention), inhibition control (suppressing dominant responses), and activation control (performing an action when intrinsic motivation is lacking) (Rothbart and Posner, 2005). Deficits in EC can have severe consequences; its antecedents need to be examined.
