Introduction: Deficits of self-regulation (SR) are a hallmark of externalizing (EXT: offending or aggressive behaviors) symptoms in adolescence. Objectives: This scoping review aims (1) to map non-pharmaceutical interventions targeting SR processes to reduce EXT symptoms in adolescents and (2) to identify research gaps, both of which will provide recommendations for future studies. Methods: Systematic searches were carried out in eight bibliographic databases up to March 2021, combining the following concepts: self-regulation, externalizing symptoms, adolescents, and non-pharmaceutical interventions. Results: We identified 239 studies, including 24,180 youths, mainly from North America, which described a plethora of non-pharmaceutical interventions targeting SR to alleviate EXT symptoms in adolescents (10–18 years of age). The majority of studies (about 70%, k = 162) represent samples with interventions exposed to “selective” or “indicated” prevention. Curriculum-based (i.e., multiple approaches targeting several domains such as emotion, cognition, and social) interventions (31.4%) were the most common type of intervention. Moreover, studies on cognitive-based interventions, mind-based interventions, and emotional-based interventions have increased over the last decades. Network analyses allowed us to identify several hubs between curriculum-based interventions, cognitive SR processes, as well as aggressiveness, conduct problems, and irritability/anger dysregulation. In addition, we identified gaps of studies concerning the physiological SR processes and on some types of interventions (i.e., body-based interventions and externally mediated interventions) or, more specifically, on promising tools, such as biofeedback, neurofeedback, as well as programs targeting neuropsychological processes (e.g., cognitive remediation). Conclusions: This scoping review stresses the plethora of interventions, identified hubs, and emerging fields, as well as some gaps in the literature, which together may orient future studies.

Deficits in self-regulatory control (SRC) represent a core characteristic of externalizing (EXT) symptoms (e.g., rule-breaking behavior or aggressive behaviors) in adolescents. This review aims to specify the added value of ecologically valid assessments at a micro-level when examining the associations between SRC and EXT symptoms in adolescents. This systematic review was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020. The search strategy addressed the added value of (1) naturalistic assessment for the understanding of the relationship between (2) SRC and (3) EXT symptoms in (4) adolescents. We conducted comprehensive searches in bibliographic databases. An additional search was conducted in Google Scholar and supplementary studies were identified through backward and forward citation tracking. Twenty-four studies (n = 4071 adolescents) met the inclusion criteria. The methods used to assess naturalistic aspects included the experience sampling method (ecological momentary- or ambulatory assessment) and the time-course approach (i.e., real-time assessment of SRC processes referring to situations approximating real-life experience where SRC are to be engaged such as in frustrating situations). Micro-level ecological assessments, when mapping the intra-individual relationships between SRC processes and EXT symptoms over time in adolescents within their natural context (i.e., real world) of expression in real time, added a finer-grained observation alongside with a higher ecological validity. Micro-level approaches may enhance the understanding of the complex interplay between SRC and EXT symptoms in adolescence, especially in interventional studies, allowing for the acquisition of endpoints with a higher relevance for everyday functioning.

IntroductionIn this study, we aimed to examine the association between aggressive ideations and aggressive behaviors in everyday life, as well as the role of processes related to self-regulatory control (i.e., self-control, ego depletion, and emotional states), using experience sampling methods (ESM).MethodsA total of 62 male adolescents performed a baseline measure of aggression, violent ideations (trait level), and ESM assessments, including four measures per day during nine consecutive days.ResultsAt a state level, aggressive ideations were associated with higher negative emotions during the previous day as well as with lower self-control and stronger anger rumination at the moment. Aggressive behaviors were related to higher anger rumination at the moment and to the manifestation of higher intensity of aggressive ideations derived in the previous measure. Higher self-control was related to a lower probability of aggressive behavior.DiscussionThis study highlights the temporal link between aggressive ideations and behaviors in everyday life as well as the role of self-control in understanding aggressivity in the lap of time. Furthermore, we observed that expressions of anger (i.e., reactivity, as well as rumination) were central in the understanding of aggressive ideations and behaviors in the everyday life (i.e., at within-person variability at the state level).
