Impulsivity is clearly associated with adolescent substance use. However, contemporary models of impulsivity argue against a unitary construct and propose at least two potential facets of impulsivity: reward drive and disinhibition. This study investigated the mediating role of prosocial risk‐taking in the association between these two facets of impulsivity, family environment, and substance use in Grade 8 students, age 12–14 years (N = 969). For girls, traits related to disinhibition referred to as rash impulsivity were directly associated with greater substance use and, unexpectedly, reward drive was indirectly associated with greater substance use through participation in physical‐risk activities, which itself predicted greater use. For boys, participation in physical‐risk activities was the only direct predictor of substance use and, as in girls, reward drive conveyed indirect risk through this pathway. Family environment, reward drive, and rash impulsivity were associated with participation in performance‐risk activities, and prosocial behavior more generally, but neither of these hypothesized mediators was related to substance use.

Objective Research and theory suggest the aetiological nature and symptomatic profile of eating disorders (EDs) can be explained by multiple factors, including the development of early maladaptive schemas (EMS). Yet, there is lack of consensus regarding the evidence supporting the relationship between EMS and EDs. Therefore, this systematic review aimed to examine existing literature concerning the relationship between different ED diagnoses and EMS to provide a synthesis and evaluation of relevant research. Method A comprehensive literature search of four electronic databases was conducted and studies were included that examined the association between EMS and EDs. Studies were required to use a variant of Young Schema Questionnaire and establish ED diagnosis or symptomology using self‐report questionnaires or clinical interview. Results A total of 29 studies were included in the review. Compared to healthy controls and varying clinical populations, individuals with EDs generally reported significantly higher scores across all EMS except for Entitlement. Furthermore, Unrelenting Standards consistently appeared as a significant EMS across all ED diagnoses whilst Insufficient Self‐Control was significantly lower in ED diagnoses with restrictive behaviour compared to diagnoses with binge eating or purging behaviour. Discussion Research supports significant associations between EMS and EDs, which may contribute to our understanding of ED aetiology, including different diagnostic categories. This review underscores the need for studies to explore more gender and age diverse samples and highlights important implications for practitioners.
