Applying an Evolutionary Approach of Risk-Taking Behaviors in Adolescents

Risk-taking behaviors in adolescents have traditionally been analyzed from a psychopathological approach, with an excessive emphasis on their potential costs. From evolutionary theory we propose that risk-taking behaviors can be means through which adolescents obtain potential benefits for survival and reproduction. The present study analyses sex differences in three contexts of risk (i.e., risk propensity, expected benefits and risk perception) in the evolutionary specific domains and the predictive value of these domains over risk-taking behaviors, separately in female and male adolescents. 749 adolescents (females = 370) valued their risk perception, expected benefits and risk propensity through the Evolutionary Domain-Specific Risk Scale, as well as their engagement in risk-taking behaviors through the Risky Behavior Questionnaire. Male adolescents showed lower risk perception in two evolutionary domains, expected higher benefits in two other domains and showed higher risk propensity in six domains. Female adolescents showed lower risk perception in two domains. Additionally, risk perception, expected benefits and risk propensity in the evolutionary domains predicted the engagement in risk-taking behaviors in male adolescents, whereas in female adolescents only expected benefits and risk propensity showed a predictive effect over risk-taking behaviors. These results suggest the potential role of evolutionary mechanisms on risk-taking behaviors in adolescents. Results have practical implications for interventions programs aimed at reducing risk-taking behaviors. In addition to considering sex differences, intervention programs should consider alternative behaviors through which adolescents can reach their evolutionary goals, and handle the risks related to those behaviors that cannot be replaced but have potential benefits for adolescents.

Effects of an intensive slow cortical potentials neurofeedback training in female and male adolescents with autism spectrum disorder

Summary Background This study aims to compare the effects of neurofeedback training on male and female adolescents with autism spectrum disorder (ASD). Furthermore, it examines sex differences regarding improvements in co-occurring psychopathological symptoms, cognitive flexibility and emotion recognition abilities. The study might provide first hints whether there is an influence of sex on treatment outcomes. Methods Six female and six male adolescents with ASD were matched according to age, IQ and symptom severity. All participants received 24 sessions of electroencephalography-based neurofeedback training. Before and after the intervention, psychological data for measuring co-occurring psychopathological symptoms as well as behavioral data for measuring cognitive flexibility and emotion recognition abilities were recorded. Results Caregivers rated statistically significant higher psychopathological problems in female than in male adolescents with ASD at baseline. Apart from that, no statistically significant sex-related differences were revealed in this sample; however, male adolescents tended to report greater improvements of externalizing, internalizing and total symptoms, whereas females experienced smaller improvements of externalizing and total problems, but no improvements of internalizing problems. Regarding caregivers’ assessments, more improvement of total problems was reported for females. For males, only improvements of internalizing and total problems were described. Conclusion This study reveals preliminary results that sex-related differences might play a role when evaluating treatment outcomes after neurofeedback training regarding comorbid psychopathological symptoms. Adolescents’ self-report and parental assessments, especially concerning psychopathological symptoms, should be combined and considered in future studies to help prevent sex bias in adolescents with ASD.

Traumatic injuries in children and youth from Southern Brazil: A cross-sectional study

Objectives: The objective of the study was to identify the prevalence of firearm injuries (FI) and bladed weapon injuries (BWIs) in underage people and their respective outcomes. Methods: Using a retrospective observational design, data were recorded on patients who met the inclusion criteria receiving care in a public hospital between June 30, 2015, and June 30, 2018. Results: Ninety-one medical records were found, 76.9% of patients were males and 23.1% were females. Most injuries were caused by firearms (76%) and the remainder by bladed weapons (24%). The majority of patients were 12–18 years old (92.3%), while 7.7% were 6–12 years old. Male participants were the ones who most needed medical care (77%). Male adolescents in the older age group with injury-associated fractures (P = 0.015 and P = 0.032) accounted for the most common association in the sample, demonstrating greater susceptibility to fractures in these groups. Analysis of detailed location proved that BWIs BWIs were the leading cause of injuries to soft abdominal organs (P = 0.011). Conclusion: The occurrence of FI and BWIs in the pediatric population is significant and can imply death and tragic sequelae. Emergency services need to be prepared to provide care to these victims, particularly males and the 12–18 age range, as these are the most affected groups. Further studies should be conducted on this theme to gain a greater and better understanding of the etiology and repercussions of this type of injury in the lives of young patients.

How is Online Disinhibition Related to Adolescents’ Cyberbullying Perpetration? Empathy and Gender as Moderators

The present study examined the relationship between online disinhibition and adolescents’ cyberbullying perpetration and investigated whether empathy and gender would moderate this relationship. A total of 2407 Chinese adolescents aged 11–16 years completed the questionnaires to measure their online disinhibition, empathy, and cyberbullying perpetration. Results indicated that high levels of online disinhibition were associated with high levels of cyberbullying perpetration, even after controlling for key covariates related to cyberbullying perpetration. Empathy significantly moderated the relationship between online disinhibition and cyberbullying perpetration. Specifically, this relationship was not significant at high levels of empathy. Moreover, the impact of empathy was moderated by gender. For male adolescents, online disinhibition was significantly associated with cyberbullying perpetration only when their empathy was low. For female adolescents, the relationship between online disinhibition and cyberbullying perpetration became nonsignificant, regardless of whether they had a low or high level of empathy.

Changes in pulmonary function after long-duration adventure racing in adolescent athletes

The present study investigated the acute effects of a mixed-modality, long-duration adventure race on pulmonary function in adolescent athletes. Twenty male adolescents aged 14 to 17 years volunteered to participate in a wilderness adventure race of 68.5-km. Expiratory function was evaluated before, immediately after, and 24 h after race completion. Measurements included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and peak expiratory flow (PEF). Maximal inspiratory and expiratory mouth static pressures (MIP and MEP, respectively) were also measured using a portable hand-held mouth pressure meter across the same time points. The mean completion time of the race was 05:38 ± 00:20 hours. A significant post-race decrease in FVC was observed immediately after the race (-5.2%, p = 0.01). However, no significant changes were observed for FEV1, PEF and the FEV1/FVC and FEV1/PEF ratios. In addition, estimates of respiratory muscle strength (MIP and MEP) were unaffected by the race. The long-duration adventure race induced no marked reduction in expiratory pulmonary function and this response was associated with no apparent respiratory muscle fatigue. Therefore, the pulmonary system of trained adolescent athletes was sufficiently robust to sustain the mixed-modality, long-duration adventure race of ∽5-6 h.

Optimizing Urban Forest Landscape for Better Perceptions of Positive Emotions

Interacting with urban spaces that are green and blue is believed to promote mental well-being and positive emotions. Therefore, there is an incentive to strategically design urban forest landscapes in a given space to evoke more positive emotion. In this study, we conducted a pilot study in Northeast China with 24 parks from 11 cities across 3 provinces. The subjects of the study are the visitors and a total of 1145 photos and selfies were collected from open micro-twitters in Sino Weibo (~50 individuals per park). Facial expressions of happy and sad emotions were recognized and rated as percent scores by FireFACE v1.0. Demographically, male adolescents smiled more than male visitors in other age groups and female teens. Females expressed more positive emotions than males according to their positive response index (PRI; happy-sad). Multivariate linear regression indicated positive contribution of green space to happy scores (estimate of 0.0040) and a stronger negative contribution of blue area to sad scores (estimate of −0.1392). Therefore, an urban forest landscape can be optimized by mapping green- and blue-spaces to predict spatial distributions of positive emotions. Male teens are recommended more as frequent visitors than people in other age ranges.

CHU9D Normative Data in Peruvian Adolescents

Background: Due to the vulnerability to protective and risk factors during adolescence, there is a growing interest in the study of health-related quality of life (HRQoL) at this stage. The CHU9D is a generic and practical HRQoL instrument that provides values on all dimensions of self-perceived health, in addition to providing utilities and a cost-utility assessment fee, unlike other instruments. This study was conducted with an adolescent population in Peru. The main objective of this article is to report the normative values of the CHU9D questionnaire in Peruvian adolescents. Methods: The CHU9D questionnaire was administered to Peruvian adolescent students. A total of 1229 young people participated in the survey. The CHU9D score was reflected as a function of gender, age, weight, height, and educational level. Results: The mean CHU9D utility index for the total sample was 0.890; this rating was significantly better for boys with 0.887 and girls with 0.867. The ceiling effect was higher for male adolescents with 32.6 than for female adolescents. Conclusions: The results of the present study show that adolescents in school show a positive perception of HRQoL. It is also concluded that the CHU9D instrument can be effectively applied to economic evaluations for interventions to improve the quality of life of adolescents.

Gaming Motivation and Negative Psychosocial Outcomes in Male Adolescents: An Individual-Centered 1-Year Longitudinal Study

“Gaming motivation” is a useful concept to draw upon when considering inconsistencies in the effects of online gaming on psychosocial wellbeing. However, most prior studies that utilize it are cross-sectional and do not allow that individuals can be driven by multiple motives. The present study uses an individual-centered method to classify gaming motivation styles of male adolescents and longitudinally observes the relationship between gaming motivations and psychosocial outcomes. A total of 929 healthy, male, adolescent gamers were recruited in October 2019 and classified into “recreational” “achiever,” and “escaper” categories according to their baseline gaming motivations and self-esteem levels. Then, 1-year incidence rates of players and relative risks (RRs) of social withdrawal problems, anxiety/depression syndrome, and self-destructive/identity problems were assessed. Recreational players were found to have the lowest incidence of all the three psychosocial problems among the three categories, achievers only had a moderate risk of social withdrawal, compared to recreational players, while escapers showed a strong risk for social withdrawal, anxiety/depression, and self-destructive/identity problems, relative to recreational gamers. Overall, the different motivation subgroups were associated with different psychosocial problems. Both achievers and escapers were found to be maladaptive, but their psychosocial outcomes were different, a finding that provides further insight into the psychological mechanisms underlying these subgroups.
