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., Author(s): Melissa Tracy [sup.1] , Li Shen Chong [sup.2] , Kate Strully [sup.3] , Elana Gordis [sup.2] , Magdalena Cerdá [sup.4] , Brandon D.

The link between childhood harsh parenting and later aggression is well established. However, harsh parenting may occur within the context of nonviolent discipline. Moreover, sympathetic nervous system activity may moderate the effects of harsh parenting on aggression. This study examined whether sympathetic nervous system activity, measured by skin conductance level (SCL), and childhood nonviolent discipline moderate the link between childhood harsh parenting and later aggression among emerging adults. Participants (N = 264, mean age = 19.37, 54% females) reported retrospectively on experiences of childhood harsh parenting and nonviolent discipline as well as current anger, hostility, verbal, and physical aggression. We also measured resting SCL. Regression analyses revealed a significant three-way interaction between childhood harsh parenting, nonviolent discipline, and resting SCL accounting for anger and a significant two-way interaction between childhood harsh parenting and resting SCL accounting for hostility. Results suggested that (1) at high levels of resting SCL and low levels of childhood nonviolent discipline and (2) at low levels of resting SCL and high levels of childhood nonviolent discipline, the link between childhood harsh parenting and anger was stronger. Moreover, the association between childhood harsh parenting and hostility was stronger among participants who exhibited high resting SCL. The findings are consistent with the biological sensitivity to context theory. Our study highlighted the importance to examine the influence of both environmental and biological variables underlying emerging adults' aggression. [ABSTRACT FROM AUTHOR]

Transcendental meditation (TM) is effective in alleviating stress and anxiety and promoting well-being. While the underlying biological mechanisms of TM are not yet fully explored, the hypothalamic-pituitary-adrenal (HPA) axis represents an index providing important clues embodying the stress system cascade. In this pilot study, young adults were randomly assigned to TM training followed by 8 weeks of meditation practice or a wait-list control condition. TM was conducted over 8 weeks. Thirty-four young adult participants were randomized; 27 participants completed the HPA outcome assessments (41% male). To assess HPA axis functioning, salivary samples to assess cortisol awakening response (CAR) that were collected in the morning, both at baseline and at week-4. Salivary cortisol in the context of a social stressor using the Trier Social Stress Test (TSST) was collected at week-8. The results indicate that participants who were randomly assigned to TM had lower awakening salivary cortisol levels and a greater drop in CAR from baseline to week-4 than the control group. There were no significant differences in HPA axis functioning in the context of the TSST. Primary limitations of this randomized controlled trial were the small sample size, the use of a wait-list as opposed to an active control, and the limited scope of HPA axis assessments. The results of this pilot study provide tentative evidence that TM may impact biological stress system functioning and suggests that this may be a worthwhile avenue to continue to examine. It will also be useful to extend these findings to a broader array of meditative and mindful practices, particularly for those who are experiencing more distress. [ABSTRACT FROM AUTHOR]

Purpose: Effective pain management is vital for hip fracture recovery, yet the factors influencing pain reporting and pain medication use during inpatient rehabilitation for hip fractures are not well understood. This observational study aimed to (a) determine how cognitive abilities, expressive and receptive language abilities, and age are related to average daily pain intensity and analgesic use and (b) how average daily pain intensity and analgesic use are related to length of stay and functional outcomes in rehabilitation., Design: Data were retrospectively obtained from 163 patients recovering from unilateral trochanteric fractures of the femur., Results: During the first week of rehabilitation, patients received a daily average of 1,147.8 ± 978 mg of acetaminophen and a morphine milligram equivalent of 15.3 ± 18.2. Multivariable regression revealed independent relationships between more intact general cognitive abilities ( B = -0.40, 95% CI [-0.70, -0.11]), and older age ( B = -0.41, 95% CI [-0.70, -0.11]) with lower average daily pain intensity. Higher average daily pain intensity ( B = 0.97, 95% CI [0.75, 1.20]) was independently related to greater opioid use. The length of stay was shorter among patients administered higher daily doses of acetaminophen ( B = 0.03, 95% CI [-0.05, -0.01]). Average daily pain intensity and analgesic use were not related to functional outcomes in multivariable models., Conclusions: These findings inform the considerations for assessing and treating pain during inpatient rehabilitation. Supplemental strategies for assessing pain in older patients and alternative pain mitigation strategies for patients with impaired cognitive abilities should be considered.

The cortisol awakening response (CAR) has been associated with depression and a broader range of internalizing problems. Emerging adulthood is characterized by numerous stressful transitional life events. Furthermore, the functioning of the neurobiological stress system changes across development. These considerations underscore the importance of evaluating the physiological stress system in emerging adults in identifying the extent to which cortisol levels vary with risk and protective factors for mental health. The present study evaluated the association between internalizing symptoms and perceived life satisfaction with CAR in 32 young adults. Three saliva samples were collected to measure cortisol levels upon awakening and participants completed the Depression Anxiety Stress Scale (DASS) and Satisfaction with Life Scale (SWLS). Results show a significant positive correlation between area under the curve for CAR with internalizing symptoms (DASS total) and the DASS-depression subscale, but not with life satisfaction. Study limitations, implications, and future directions for these finding were discussed., Competing Interests: The authors declare no conflicts of interest.
