Emotional and physiological desensitization to real-life and movie violence

Critical Clinical Events and Resilience Among Emergency Nurses in 3 Trauma Hospital-Based Emergency Departments: A Cross-Sectional Study

INTRODUCTION

Emergency nurses experience occupational stressors resulting from exposures to critical clinical events. The purpose of this study was to identify the critical clinical events for emergency nurses serving 3 patient populations (general, adult, pediatric) and whether the resilience of these nurses differed by the patient population served.

METHODS

This study used a cross-sectional survey design. A total of 48 emergency nurses were recruited from 3 trauma hospital-based emergency departments (general, adult, pediatric). Clinical Events Questionnaire, Connor-Davidson Resilience scale, and an investigator-developed demographic questionnaire were used to collect data from respondents.

RESULTS

All respondents were female (n = 48, 100%), and most were White (n = 46, 96%). The average age of participants was 39.6 years, the average number of years as a registered nurse was 12.7 years, and the average number of years as an emergency nurse was 8.8 years. Clinical events considered most critical were providing care to a sexually abused child, experiencing the death of a coworker, and lack of responsiveness by a colleague during a serious situation. The least stress-provoking event was incidents with excessive media coverage. Nurses were less affected by the critical events they experienced more frequently at work. Nurses in the 3 trauma settings had high level of resilience, with no statistically significant differences between groups.

DISCUSSION

The occupational stress from exposure to significant clinical events varied with the patient population served by emergency nurses. It is important that interventions be adopted to alleviate the effect of work-related stressors and promote the psychological health of emergency nurses.

Does Perceived Stress of University Students Affected by Preferences for Movie Genres? an Exploratory Cross-Sectional Study in China

This study aims to explore whether different preferences for movie genres were related to different perceived stress of college students. An online questionnaire was designed and it was filled out by 1,549 students voluntarily. The 10-item perceived stress scale (PSS-10) and multinomial logistic regression were used to access the perceived stress and the association between the movie preference genres. Over 90% of participants had mild to serious levels of stress. Differences were found between participants with different stress perception states in terms of smoking history, active exercise, and sleep duration (p < 0.05). The participants who showed a preference for suspense movies more probably had lower stress [relative risk ratio (RRR)1 = 0.34, RRR2 = 0.26, p < 0.05], while students who showed preferences for crime film and disaster film more probably had higher stress (RRR = 2.03, p < 0.05, RRR = 3.15, p < 0.05). And the significant gender gap in different film genre preferences was observed in this study (p < 0.05). The males who showed preference for horror movies were more probably to have moderate stress (OR = 3.68, p < 0.05), and females who showed a preference for disaster movies were more probably to have high stress (OR = 3.27, p < 0.05). The perceived stress of Chinese university students is high after 1.5 years of coronavirus disease (COVID-19) pandemic. The personal preferences for certain film genres were significantly associated with perceived stress. As different film genre preferences, such as the preference for disaster, crime, and horror, are associated with high perceived stress, it may turn out to be useful to pay more attention to an individual's film viewing. The teachers need to be concerned with the media usage history and preferences of their students and may advise students with high-level stress to avoid potentially harmful media content.

Fatigue influence on inhibitory control: Cardiovascular and performance findings elucidate the role of restraint intensity

Various papers have detailed an analysis of behavioral restraint that provides suggestions regarding fatigue influence on inhibitory control. A well-known limited resource model by Baumeister suggests that fatigue should directly impair it. By contrast, the behavioral restraint analysis suggests-first-that fatigue might affect control indirectly by impacting the intensity of restraint. Second, fatigue should impair control consistently only when it leads people to withhold restraint effort. We evaluated these suggestions in an experiment that presented participants a task designed to induce low- or high- mental fatigue and then challenged them to maintain a neutral facial expression while watching a more- or less emotionally evocative film clip. As expected, cardiovascular assessments during the facial restraint period revealed interactional response patterns indicative of opposing fatigue influence on restraint intensity under low- as compared to high-evocativeness conditions. Also as expected, fatigue combined with evocativeness to produce a three versus one pattern of inhibitory control operationalized in terms of the duration of non-neutral facial displays. Control failure increased with evocativeness only when fatigue was high and increased with fatigue only when evocativeness was high. Findings support the restraint analysis suggestions, extend results from previous research, and bear out the promise of the restraint analysis for advancing understanding of inhibitory control.

Self-Reported Lifetime Violence Exposure and Self-Compassion Associated With Satisfaction of Life in Historically Black College and University Students

In the United States, approximately 25% of minors have witnessed a violent act, specifically physical assault. African Americans from under-served backgrounds are more likely than other racial and ethnic groups to be exposed to traumatic events. However, there is scant literature examining violence exposure, SC, and life satisfaction collectively, specifically in an African American college sample. The current study sought to determine the associations among violence exposure, SC components, and life satisfaction in an African American college sample. The current sample was comprised of 356 participants (80% female) with a mean age of 20.23 (SD = 1.70). Eighty-eight participants (25%) reported being exposed to violence in their lifetime. Employing logistic regression, we determined violence exposed individuals were less likely to report high satisfaction of life than their non-exposed counterparts (OR = 0.58, 95% CIs = 0.33, 1.00). Individuals with high level of self-kindness were approximately two times more likely to have higher satisfaction of life (OR = 2.48; CI = 1.52, 4.05) compared to their low level self-kindness counterparts and in the presence of demographic covariates. These findings may educate and increase awareness of the impacts of traumatic events. This education could lead to the implementation of interventions to build upon overall well-being in order increase life satisfaction in college students.

Understanding and supporting law enforcement professionals working with distressing material: Findings from a qualitative study

This study aimed to extend previous research on the experiences and factors that impact law enforcement personnel when working with distressing materials such as child sexual abuse content. A sample of 22 law enforcement personnel working within one law enforcement organisation in England, United Kingdom participated in anonymous semi-structured interviews. Results were explored thematically and organised in the following headings: "Responses to the material", "Impact of working with distressing evidence", "Personal coping strategies" and "Risks and mitigating factors". Law enforcement professionals experienced heightened affective responses to personally relevant material, depictions of violence, victims' displays of emotions, norm violations and to various mediums. These responses dampened over time due to desensitisation. The stress experienced from exposure to the material sometimes led to psychological symptoms associated with Secondary Traumatic Stress. Job satisfaction, self-care activities, the coping strategies used when viewing evidence, detachment from work outside working hours, social support and reducing exposure to the material were found to mediate law enforcement professionals' resilience. Exposure to distressing material and the risks associated with this exposure were also influenced by specific organisational procedures implemented as a function of the funding available and workload. Recommendations for individual and organisational practices to foster resilience emerged from this research. These recommendations are relevant to all organisations where employees are required to view distressing content.

Do pictures really say more than a thousand words? A network approach to early traumatic experience and empathic responding

Background: Empathy is essential for interpersonal relationships, yet remains difficult to measure. Some evidence suggests that early traumatic experiences leads to alterations in empathic responding. Objective: This study sought to differentiate connections between subtypes of childhood maltreatment, a pictorial test of affective empathy (PET), and self-reported empathy (Interpersonal Reactivity Index; IRI) by using network analysis approach to investigate the structure of relationships between childhood maltreatment and later empathic responding. Method: 301 participants completed the PET, the Early Trauma Inventory Self Report-Short Form (ETISR-SF), the IRI, and questionnaires assessing current mood and perceived stress levels. Results: The PET showed a strong positive association with the IRI subscale empathic concern (EC), after conditioning on all other nodes in the network. EC proved to be a highly central node and was positively related to severity of childhood sexual abuse (CSA), yet not to childhood physical abuse or emotional maltreatment. Pathways between emotional maltreatment and physical abuse and the PET were indirect, passing through self-reported EC and CSA. Conclusions: Our study suggests that CSA more so than other childhood maltreatment experiences is associated with increased self-reported affective empathy, but is not captured directly through a pictorial test of affective empathy.

Effortful Control and Community Violence Exposure as Predictors of Developmental Trajectories of Self-serving Cognitive Distortions in Adolescence: A Growth Mixture Modeling Approach

Self-serving cognitive distortions are biased or rationalizing beliefs and thoughts that originate from the individual persistence into immature moral judgment stages during adolescence and adulthood, increasing the individual’s engagement in antisocial or immoral conducts. To date, the literature examining trajectories of cognitive distortions over time and their precursors is limited. This study sought to fill this gap, by examining effortful control and community violence exposure as individual and environmental precursors to developmental trajectories of cognitive distortions in adolescence. The sample consisted of 803 Italian high school students (349 males; M_age = 14.19, SD = 0.57). Three trajectories of cognitive distortions were identified: (1) moderately high and stable cognitive distortions (N = 311), (2) moderate and decreasing cognitive distortions (N = 363), and (3) low and decreasing cognitive distortions (N = 129). Both low effortful control and high exposure to community violence were significant predictors for moderately high and stable trajectory of cognitive distortions. These results point to the importance of considering moral development as a process involving multiple levels of individual ecology, highlighting the need to further explore how dispositional and environmental factors might undermine developmental processes of morality.

Exploring adversities among parents convicted of killing their children

Experiencing adversities has been associated with the use of violence but this has not been explored with filicide offenders in South Africa. Individual, semi-structured interviews were conducted with 22 parents/stepparents/caregivers convicted of child homicide in South Africa, resulting in 49 in-depth interviews. Data were analyzed by means of grounded theory. Using an ecological framework, this study alludes to the widespread and cumulative nature of violence and trauma experiences within multiple domains of the participants' lives. The study highlighted the absence of support in the aftermath of experiencing trauma, possibly resulting in these parents lacking resources to mitigate the sequelae of adverse experiences. This study calls for trauma related, mental health components to be integrated into violence interventions and for these to address the impact of trauma at the individual, family, and societal levels, to prevent the transition from victim to offender.

Black Lives Matter, and Yes, You are Racist: The Parallelism of the Twentieth and Twenty-First Centuries

The United States of America is at a crossroads, one that we have been at before. This is not the first time that we have battled a pandemic while experiencing an economic downturn, state sanctioned violence and racial terror against Blacks, the boiling over of racial tensions encouraged by the president of the United States, and a movement focused on forcing America to reckon with its endemic racism, anti-Blackness, and state-sanctioned violence against Blacks. This article provides a brief overview of that history and its striking parallel to what is happening today. It pushes White social workers to understand how they are beneficiaries of racism. It reminds social workers of their ethical obligation to be change agents. Finally, it provides basic suggestions for those who are willing to see their complicity and are still willing to work on dismantling the injustice that impacts Black people in America.

Cognitive-Emotional and Inhibitory Deficits as a Window to Moral Decision-Making Difficulties Related to Exposure to Violence

In the present review, we illustrate how exposure to violence results in an increased probability of developing functional impairments of decision mechanisms necessary for moral behavior. We focus in particular on the detrimental effects of exposure to violence on emotional (e.g., Empathy), cognitive (e.g., Theory of Mind), and inhibitory control abilities. Relying on studies that document impaired moral behavior in individuals with deficits in these abilities, we propose a "model" of how exposure to violence can affect moral behavior. We then discuss how impaired moral decision making can also be a factor increasing the likelihood of reiterating violence: agents who lack abilities such as understanding and resonating with others' emotions or inhibitory control, can lead to an increase of violent displays. Thus, if not properly addressed, the noxious effects of exposure to violence on morality can lead to a violence generating cycle. We conclude proposing that interventions targeted at improving moral behavior can maximize their efficacy focusing on mitigating the impact of violence on the basic cognitive, emotional, and inhibitory abilities discussed.

Movie violence acutely affects food choices in young adults

BACKGROUND

Extensive research has been conducted to investigate the effects of media violence on attitudes, behaviors, and cardiovascular health; however, only few studies have examined its effect on appetite, eating behavior and food preferences. Little attention has been given to understand how movie genre manipulates the physiology and the eating behavior of individuals. The present study aimed at investigating the acute effect of violence content in movies on appetite perception, heart rate and blood pressure, along with food preferences and intake in young individuals.

METHODS

Participants (n = 84) were randomly assigned to either watch a violent movie or a non-violent narrative movie. Measurements including anthropometry, heart rate, blood pressure and grip strength were taken and appetite as well as stress perception were assessed. Subjects were then provided with an individual snack tray containing various items to be consumed ad libitum.

RESULTS

Post intervention, the experimental group (EG) had a higher consumption of fatty (t (82) = 2.28, p = 0.025, d = 1.52) and salty (t (82) = 2.61, p = 0.01, d = 0.71) food items compared to the control group (CG). Out of the 42 participants in the EG 62% consumed >2 fatty items and 71.4% consumed >2 salty food items. No significant difference in the consumption of sugary items was observed between the two groups.

CONCLUSION

Movie violence affects eating behavior and may promote weight gain.

Violence exposure is associated with adolescents' same- and next-day mental health symptoms

BACKGROUND

Young people exposed to violence are at increased risk for mental health and behavioral problems. However, very little is known about the immediate, or same-day, associations between violence exposure and adolescents' mental health symptoms or whether daily symptom or behavioral reactivity marks future problems.

METHODS

Young adolescents were assessed three times a day for 30 consecutive days using mobile-phone-based Ecological Momentary Assessment (EMA) (N = 151 adolescents). Over 12,500 assessments and 4,329 person days were obtained via the EMA. Adolescents were recruited from low-income neighborhoods based on parent-reported risk for externalizing symptoms. Mental health symptoms were assessed via parent and child report at baseline, multiple times per day via EMA assessments of the adolescents, and again 18 months later when 93% of the adolescents were reinterviewed.

RESULTS

Results from multilevel models illustrated that young adolescents were more likely to experience symptoms of anger (OR = 1.74, CI: 1.31-2.30), depression (OR = 1.66, CI: 1.26-2.19), and conduct problems (OR = 2.63, CI: 1.71-4.04) on days that they were exposed versus not exposed to violence. Increases in depressive symptoms were also observed on days following violence exposure (OR = 1.46, CI: 1.09-1.97). Adolescents with the highest levels of violence exposure across the 30-day EMA were less behaviorally reactive to violence exposures in daily life, and heightened behavioral reactivity predicted increased risk for substance use across early adolescence.

CONCLUSIONS

Findings support the need to focus on both the immediate and long-term associations between violence exposure and adolescents' mental health and behavior. Results also suggest that heightened behavioral reactivity during early adolescence may signal emerging substance use problems.

Long-Time Exposure to Violent Video Games Does Not Show Desensitization on Empathy for Pain: An fMRI Study

As a typical form of empathy, empathy for pain refers to the perception and appraisal of others’ pain, as well as the corresponding affective responses. Numerous studies investigated the factors affecting the empathy for pain, in which the exposure to violent video games (VVGs) could change players’ empathic responses to painful situations. However, it remains unclear whether exposure to VVG influences the empathy for pain. In the present study, in terms of the exposure experience to VVG, two groups of participants (18 in VVG group, VG; 17 in non-VVG group, NG) were screened from nearly 200 video game experience questionnaires. And then, the functional magnetic resonance imaging data were recorded when they were viewing painful and non-painful stimuli. The results showed that the perception of others’ pain were not significantly different in brain regions between groups, from which we could infer that the desensitization effect of VVGs was overrated.

Lack of Evidence That Neural Empathic Responses Are Blunted in Excessive Users of Violent Video Games: An fMRI Study

The use of violent video games has been often linked to increase of aggressive behavior. According to the General Aggression Model, one of the central mechanisms for this aggressiveness inducing impact is an emotional desensitization process resulting from long lasting repeated violent game playing. This desensitization should evidence itself in a lack of empathy. Recent research has focused primarily on acute, short term impact of violent media use but only little is known about long term effects. In this study 15 excessive users of violent games and control subjects matched for age and education viewed pictures depicting emotional and neutral situations with and without social interaction while fMRI activations were obtained. While the typical pattern of activations for empathy and theory of mind networks was seen, both groups showed no differences in brain responses. We interpret our results as evidence against the desensitization hypothesis and suggest that the impact of violent media on emotional processing may be rather acute and short-lived.

Emotional Desensitization to Violence Contributes to Adolescents' Violent Behavior

Many adolescents are exposed to violence in their schools, communities and homes. Exposure to violence at high levels or across multiple contexts has been linked with emotional desensitization, indicated by low levels of internalizing symptoms. However, the long-term consequences of such desensitization are unknown. This study examined emotional desensitization to violence, together with externalizing problems, as mediators of the relationship between exposure to violence in pre-adolescence and violent behavior in late adolescence. A community sample of youth (N = 704; 48% female; 76% African American, 22% Caucasian) reported on their exposure to violence in multiple settings at ages 11, 13 and 18. Internalizing and externalizing problems were assessed at ages 11 and 13; violent behavior was measured at age 18. Structural Equation Modeling showed that exposure to high levels of violence at age 11 was associated with lower levels of internalizing problems (quadratic effect) at age 13, as was exposure to violence across multiple contexts (linear effect). In turn, fewer internalizing problems and more externalizing problems at age 13 predicted more violent behavior at age 18. The results suggest that emotional desensitization to violence in early adolescence contributes to serious violence in late adolescence.
