Purpose : Exposure to aggressive parenting is a well-established environmental risk factor for anxiety symptoms. Moreover, autonomic nervous system (ANS) activity, including activity in both parasympathetic and sympathetic nervous systems (PNS and SNS), may moderate the effects of aggressive parenting on anxiety. This study aims to examine the interactive effects of aggressive parenting and ANS activity (both PNS and SNS) in accounting for trait anxiety among emerging adults. Methods: Participants (n = 190, mean age = 19.29, 56% females) reported retrospectively on childhood aggressive parenting and trait anxiety. In addition, we measured resting respiratory sinus arrhythmia (RSA), an index of PNS, and resting skin conductance level (SCL), an index of SNS. Results: Regression analyses revealed that the three-way interaction between resting SCL, RSA, and aggressive parenting significantly accounted for trait anxiety. Simple slope analyses suggest that the relation between aggressive parenting and trait anxiety is stronger at lower conditional values of resting RSA and lower conditional values of resting SCL. Conclusion: Coinhibition, or relatively low activity across both systems, may exacerbate the link between aggressive parenting and trait anxiety. This study highlights the importance of considering the interaction effects of multiple physiological systems and environmental context on later psychological functioning. [ABSTRACT FROM AUTHOR]

Purpose: We aimed to synthesize insights from systems science approaches applied to domestic and gender-based violence. Methods: We conducted a systematic review of systems science studies (systems thinking, group model-building, agent-based modeling [ABM], system dynamics [SD] modeling, social network analysis [SNA], and network analysis [NA]) applied to domestic or gender-based violence, including victimization, perpetration, prevention, and community responses. We used blinded review to identify papers meeting our inclusion criteria (i.e., peer-reviewed journal article or published book chapter that described a systems science approach to domestic or gender-based violence, broadly defined) and assessed the quality and transparency of each study. Results: Our search yielded 1,841 studies, and 74 studies met our inclusion criteria (45 SNA, 12 NA, 8 ABM, and 3 SD). Although research aims varied across study types, the included studies highlighted social network influences on risks for domestic violence, clustering of risk factors and violence experiences, and potential targets for intervention. We assessed the quality of the included studies as moderate, though only a minority adhered to best practices in model development and dissemination, including stakeholder engagement and sharing of model code. Conclusions: Systems science approaches for the study of domestic and gender-based violence have shed light on the complex processes that characterize domestic violence and its broader context. Future research in this area should include greater dialogue between different types of systems science approaches, consideration of peer and family influences in the same models, and expanded use of best practices, including continued engagement of community stakeholders.
