Physical Violence Perpetration Among College Students: Prevalence and Associations With Substance Use and Mental Health Symptoms

Epidemiology of Craniomaxillofacial Fractures Over a 5-year Period at a Midwestern Level 1 Trauma Center Serving a Large Rural Population

BACKGROUND

Though the epidemiology of craniomaxillofacial (CMF) fractures has been well documented at urban hospitals, the characteristics of these fractures in rural hospitals have not been well studied.

PURPOSE

The purpose of this study is to report on the epidemiology of CMF fractures at a regional Level 1 trauma center serving a large rural population in central Illinois.

STUDY DESIGN, SETTING, SAMPLE

This is a retrospective cohort study at a community-based regional tertiary referral center that serves a predominantly rural population. Inclusion criteria comprised patients with radiologically confirmed CMF fractures between 2015 and 2019. Patients with incomplete medical records were excluded.

PREDICTOR VARIABLE

Predictor variables included demographics (age, admission source, race, and sex) and etiology of CMF fracture (assault/domestic violence, all-terrain vehicle/off-road, falls, farm-related, motor vehicle collisions, gunshot wound, and others).

MAIN OUTCOME VARIABLE

The primary outcome variable was the CMF anatomic location including nasal bone, orbit, mandible, malar/maxillary, and other CMF fractures.

COVARIATES

The covariates are not applicable.

ANALYSES

Descriptive statistics were used to summarize a sample of the population characteristics. Wilcoxon ranked sign tests and χ2 tests of independence were used to assess for statistically significant associations between select variables of interest. Statistical significance was defined as P < .05.

RESULTS

Between 2015 and 2019, a total of 2,334 patients presented to the emergency department with a CMF fracture. After applying the inclusion/exclusion criteria, the final sample was composed of 1,844 patients for the management of 2,405 CMF fractures. The majority of patients were male(62.0%) and young adults (aged 18-39) had the highest number of CMF fractures (819) relative to all other age groups. The most common fracture etiology was fall(37.3%), and nasal bone fractures represented the most common fracture location(41.6%). χ2 analyses revealed statistically significant associations between the anatomic location of CMF fracture incurred, and differing categories of age, admission source, race, sex, and etiology.

CONCLUSION AND RELEVANCE

Our study shows that patients seen at our Midwestern Level 1 trauma center are more likely to present with nasal bone and malar/maxillary fractures due to falls. In studies based in urban centers, patients are likely to present with orbital and mandibular fractures due to falls and assault.

Association between psychological flexibility and physical violence perpetration in college student populations: results from the national Healthy Minds Study

ObjectiveTo investigate the association between psychological flexibility and physical violence perpetration among a large sample of college students. Participants: We analyzed data from the 2018-2019 national Healthy Minds Study, which included 21,850 undergraduate and graduate student participants at 78 U.S. campuses. Methods: We used multivariable logistic regression analysis to estimate the association between psychological flexibility, measured by the Acceptance and Action Questionnaire-II (AAQ), and a 12-month history of self-reported physical violence perpetration. Results: Mean scores on the AAQ were higher (p < 0.001) among participants who reported physical violence perpetration (25.6, SD 10.7) compared to those who did not (21.7, SD 9.9). Logistic regression results revealed that psychological inflexibility was associated with slightly higher odds of physical violence perpetration (AOR 1.03, 95% CI 1.02-1.04) while controlling for potential confounders. Conclusions: Campus violence prevention efforts should include programming aimed at increasing psychological flexibility as a means to reduce potential violence.

Dysfunctional parenting and emotional problems and substance misuse: Enhancing psychological flexibility in college students

This cross-sectional study aimed to investigate the mediating role of psychological flexibility in the relationship between dysfunctional parenting (i.e., dysfunctional parent modes) and emotional problems and substance misuse among Turkish college students. Participants were 466 undergraduate students (69% female) aged between 18 and 45 years (M = 21.46, SD = 3.31) from a public university in Turkey. The majority of participants in the study reported never or infrequent use of tobacco, alcohol, and prescription drugs, with daily or almost daily use reported by less than a quarter of the sample for each substance. Results showed that higher levels of dysfunctional parent modes were associated with increased emotional problems and substance misuse. Moreover, psychological flexibility mediated the relationship between dysfunctional parent modes and emotional problems, as well as both mediated and moderated the relationship between dysfunctional parent modes and substance misuse. Results from the study also showed that people in the at-risk group for substance misuse reported higher levels of dysfunctional parent modes and emotional problems, as well as lower levels of psychological flexibility than the typical group. These results suggest that psychological flexibility may play a significant role in the link between dysfunctional parent modes and emotional problems and substance misuse among Turkish college students. Future research should investigate whether interventions targeting psychological flexibility could be effective in reducing emotional problems and substance misuse among students with dysfunctional parent modes.

Emotional dysregulation as a mediator linking sleep disturbance with aggressive behaviors: Disentangling between- and within-person associations

PURPOSE

Sleep problems and aggressive behaviors are two prevalent and highly related problems among adolescents and emerging adults worldwide. This longitudinal study examined the reciprocal relations between sleep disturbance with aggressive behaviors and whether emotional dysregulation functioned as mediator of the relations, after separating within-person effects from between-person effects.

METHODS

A total of 4352 freshman students participated in a five-wave longitudinal study across two and half years. Data from the second wave to the fourth wave was used in this study. Random intercept cross-lagged panel models (RI-CLPM) were utilized to separate between- and within-person effects.

RESULTS

Results from RI-CLPM showed: (a) Sleep disturbance and aggressive behaviors bidirectionally predicted each other at the within-person level; (b) Emotional dysregulation functioned as a mediator of the associations from sleep disturbance to aggressive behaviors at the within-person level.

CONCLUSION

These findings advanced the literature by elucidating longitudinal associations among sleep disturbance, emotional dysregulation, and aggressive behaviors at the within-person level, suggesting that prevention and intervention programs targeted at improving emotional regulation skills may be helpful to prevent the developmental pathway from sleep disturbance to aggressive behaviors among college students.

Sexual and Gender Minority Victimization: Base Rates of Assault in College Students Across Sexual and Gender Identities

Past findings have indicated that sexual and gender minority (SGM) individuals experience disproportionate rates of emotional, physical, and sexual assault compared to their heterosexual/cisgender counterparts. While these findings are robust, many studies report homogenous groupings of SGM participants. This practice likely masks important between-group differences. We sought to address this issue by examining reported base rates of emotional, physical, and sexual assault within 12 months of data collection, split across specific sexual (heterosexual, gay/lesbian, bisexual, questioning, queer, pansexual, asexual, and demisexual) and gender (cisgender men, cisgender women, gender nonconforming female assigned at birth [FAB], and gender nonconforming male assigned at birth) identity groups. Our data came from 2020 to 2021 Healthy Minds Study, a large survey of college students living in the United States (N = 119,181). Results indicated most forms of assault were higher in SGM groups compared to heterosexual and cisgender individuals, both on univariate and multivariate (e.g., one or more type of assault) levels. Demisexual individuals reported the highest base rates for emotional assault (45.7%), whereas pansexual individuals reported highest rates of physical assault (12.5%) and sexual assault (17.3%). Demisexual individuals reported the highest multivariate base rate of experiencing at least one form of assault (49.5%), and pansexual individuals reported the highest multivariate base rate of experiencing all three forms of assault (4.7%) within the past 12 months. Gender nonconforming FAB individuals reported the highest univariate and multivariate base rates across assault types compared to all other gender identity groups. With few exceptions, compared to heterosexual and cisgender men (referents), all other sexual and gender identity groups reported significantly higher adjusted odds of experiencing each assault type. These data suggest SGM individuals experience disproportionate levels of assault.

Patterns of Violence Victimization and Disclosure Among Transgender/Gender Nonconforming and Cisgender Latinx College Students

Although research on sexual violence experiences of minoritized college students has increased in recent years, little is known about the experiences of Latinx students. Even less knowledge is available on whether such violence and disclosure experiences vary by gender identity. The present study addressed this gap by exploring the rates of sexual violence and disclosure patterns after experiences of sexual violence among Latinx college students. Using data from the 2019-2020 Healthy Minds Study, a national sample of Latinx college students was analyzed (n = 6,690). Descriptive statistics, χ² tests, and one-way analyses of variance were conducted to explore differences in gender identity, sexual violence victimization, and disclosure type. Multiple logistic regression analyses were used to estimate the association between (1) gender identity and sexual violence victimization and (2) gender identity and sexual violence disclosure while controlling for various sociodemographic measures. Results indicated sexual violence victimization occurred at significantly higher rates among transgender/gender nonconforming and cisgender women Latinx students, compared to cisgender men. Transgender/gender nonconforming students who experienced sexual violence were significantly less likely to make any disclosure of sexual violence when compared to cisgender men. These findings highlight the extent to which experiences of sexual violence among Latinx students differ based on their gender identity. It also brings attention to the need for campus programming to attend to students who often face structural barriers because of their intersecting identities, specifically transgender/gender nonconforming Latinx students.

Association between binge eating and physical violence perpetration among U.S. college students

BACKGROUND

To date, no known research has explored the link between binge eating and physical violence perpetration despite overlapping psychological constructs that underpin these behaviors (i.e., emotion regulation difficulties, impulsivity). Therefore, this study aimed to determine the association between binge eating and self-reported physical violence perpetration.

METHODS

Cross-sectional data from four survey years (2016-2020) of the national (U.S.) Healthy Minds Study (N = 6210) were analyzed. Unadjusted (Independent samples t test) and adjusted (logistic regression) analyses were conducted to determine the associations between binge eating in the past four weeks and violence perpetration in the past 12 months, while adjusting for potential confounders.

RESULTS

The unadjusted mean number of days of binge eating was significantly higher among participants who reported physical violence perpetration (M = 2.6, SD = 5.2) compared to those who did not (M = 1.8, SD = 3.7). Logistic regression analysis demonstrated that each additional day of binge eating was associated with 5% higher odds (95% confidence interval 1.02-1.09) of self-reported physical violence perpetration, while adjusting for potential confounders.

CONCLUSIONS

Results from this study are the first known to identify an association between binge eating and physical violence perpetration among U.S. college students. Findings are supported by the potential mechanistic overlap of emotion regulation and impulsivity associated with both binge eating and violence perpetration, underscoring the need for more research.

Psychological maltreatment and substance use among college students: Psychological distress, belongingness, and social support

Substance use in college students is an important public health problem associated with substantial consequences. It is a critical step to examine risk and protective factors associated with substance use to develop prevention and intervention strategies for promoting college students' healthy development and well-being. The present cross-sectional study aimed to examine the mediating role of psychological distress in the relationship between childhood psychological maltreatment and substance use and the moderating effect of social support and belongingness in this association among college students. The sample of this cross-sectional study included 382 emerging adults. Participants included 56.8% female and 43.2% male, and they ranged in age between 20 and 29 years (M = 22.05, SD = 2.17). Findings from the study first confirmed that psychological maltreatment was a significant predictor of social support, belongingness, psychological distress, and substance use. Subsequent results revealed that psychological distress mediated the association between psychological maltreatment and college students' substance use. Also, belongingness and social support had a buffering effect on this association. The findings suggest that psychological maltreatment is a significant risk factor in developing substance use behavior and that belongingness and social support services can serve as protective resources. Based on these results, prevention and intervention services focusing on improving the feeling of belonging and social support could be conducive to the decreased substance use of psychologically maltreated emerging adults.

Risk factors for intimate partner violence perpetration among college students: Impact of childhood adversities

Objective Intimate partner violence (IPV) among college students is a significant problem that negatively affects their physical and emotional health. This study aimed at examining risk factors, especially childhood adversities at the individual, relationship, and community levels, of IPV perpetration among college students. Methods: The sample from seven universities in the U.S. and Canada (N = 3,725) completed an online survey. Major variables included IPV perpetration, five types of childhood adversities, alcohol and drug use, depression, and demographic information. Logistic regression was performed. Results: Peer violence victimization, witnessing parental IPV, experiencing child maltreatment, drug use, and depression were associated with a higher odd of perpetrating IPV. Conclusions: Research and practice must account for exposure to multiple risk factors when intervening with college students. An integrative approach that combines trauma-informed interventions with substance use and mental health treatment may be most successful at IPV perpetration prevention and intervention among college students.
