Student's and Classmates' Prosocial Behavior predict Academic Engagement in Middle School.

Students' academic engagement is greatly informed by a classroom's social climate. However, more research is needed regarding how specific peer behavior, especially prosocial behavior, come to shape academic engagement. The present study investigated whether students' perceptions about their classmates' prosocial behavior were associated with their academic engagement (cognitive, behavioral, affective) across the school year. Indirect effects via increases in students' own prosocial behavior were examined. Participants were 905 middle school students from rural, low-income communities in the Midwestern United States (50% girls, 46% boys; Mage = 12.94 years). Students completed self-report surveys in the fall and spring of the 2022-2023 school year. Results revealed that students' perceptions of their classmates' prosocial behavior were positively associated with students' own prosocial behavior. Students' own prosocial behavior was positively associated with all three dimensions of engagement. The positive indirect effect of classmates' prosocial behavior on engagement through students' own prosocial behavior was significant. The findings highlight the importance of classmates' behavior on individuals' academic engagement and offer insights into classroom-based interventions aimed at improving collective behavior.

Assessing the effectiveness of virtual reality to promote empathy for patients through a mixed-methods study.

OBJECTIVE: To describe the implementation and outcomes of EmpathyVR, an immersive experience using virtual reality (VR) to promote empathy for patients with physical limitations due to chronic diseases. METHODS: First-year student pharmacists participated in a learning experience that incorporated VR and stiff gloves to simulate physical limitations associated with color-blindness and arthritis, respectively. Students completed pre- and post-intervention surveys that included the Kiersma-Chen Empathy Scale and measures of immersion, user enjoyment, perceived usefulness for learning, and adverse effects of the experience. A focus group was also conducted with 6 students to obtain additional feedback on the learning experience. RESULTS: Of the 132 students who were enrolled in the program, 131 completed the assigned tasks; 117 of these agreed to participate in the study, and their data were included in the analyses. There was a significant improvement in empathy scores in the cognitive domain from pre- to post-intervention. Post-intervention survey results also demonstrated a high degree of immersion in the experience, high levels of self-reported enjoyment, and high levels of perceived usefulness of the activity to support learning. There was a low to moderate incidence of minor self-reported adverse effects from the activity. Focus group feedback was also positive. One student stated, "… it really allowed you to think and put yourself in their shoes." CONCLUSION: Implementation of a VR-based learning activity into the first semester of the PharmD curriculum was successful and resulted in improved student empathy scores and a positive learning experience.

Developing a Multi-Tiered System of Support-Based Plan for Bullying Prevention Among Students with Disabilities: Perspectives from General and Special Education Teachers During Professional Development.

Students with disabilities or at risk for disability identification (SWD) are disproportionately affected by the bullying dynamic; however, professional development and educator-focused training on preventing bullying for this population is lacking. To address this gap, this study presents an analysis of qualitative data collected from general and special education teachers (n = 33) participating in an online professional development training using Multi-Tiered System of Supports (MTSS) to prevent bullying among students with disabilities. Braun and Clarke's six-step process was used to identify key themes and exemplar quotes from qualitative reflections collected as knowledge check responses embedded within two training modules. Three themes were identified and examined based on MTSS tiers: (1) teacher perceptions of SWD and their inclusion in a MTSS-based bullying prevention plan; (2) identifying key stakeholders for preventing bullying within a MTSS-based bullying prevention plan; and (3) potential challenges and solutions of implementing a MTSS-based bullying prevention plan within the individual, classroom, and school contexts. Findings highlight the need to educate teachers on how to use MTSS, especially for bullying prevention and interventions that are inclusive of SWD. Implications from this work extend to all students including those with mental health considerations, regardless of disability status.

Impact of Gravity Compensation on Upper Extremity Movements in Harmony Exoskeleton.

Robots have been used to offset the limb weight through gravity compensation in upper body rehabilitation to delineate the effects of loss of strength and loss of dexterity, which are two common forms of post-stroke impairments. In this paper, we explored the impact of this anti-gravity support on the quality of movement during reaching and coordinated arm movements in a pilot study with two participants with chronic stroke. The subjects donned the Harmony exoskeleton which supported proper shoulder coordination in addition to providing gravity compensation. Participants had previously taken part in seven one-hour sessions with the Harmony exoskeleton, performing six sets of passive-stretching and active exercises. Pre- and post-training sessions included assessments of two separate tasks, planar reaching and a set of six coordinated arm movements, in two conditions, outside of and supported by the exoskeleton. The movements were recorded using an optical motion capture system and analyzed using spectral arc length (SPARC) and straight line deviation to quantify movement smoothness and quality. We observed that gravity compensation resulted in an increased smoothness for the subject with high level of impairment whereas compensation resulted in a reduction in smoothness for the subject with low level of impairment in the reaching task. Both participants demonstrated better coordination of the shoulder-arm joint with gravity compensation. This result motivates further studies into the role of gravity compensation during coordinated movement training and rehabilitation interventions.

Caregiver's difficulty paying child's healthcare bills and bullying victimization of adolescents with physical disabilities.

Guided by the ecological systems perspective, the objective of the study was to examine whether caregivers' difficulty paying their child's health-care bills is associated with bullying victimization directly and indirectly through the mediating mechanisms of caregivers' frustration, adolescents' internalizing problems, and social difficulty focusing on adolescents with physical disabilities. The 2019 National Survey of Children's Health dataset, which collected data on adolescents' and caregivers' demographic characteristics and health and well-being, was used. The study sample consisted of 368 caregivers of adolescents, 12-17 years of age with physical disabilities. No direct association between caregivers' difficulty paying their child's health-care bills and bullying victimization was found. However, caregivers' frustration and adolescents' internalizing problems were shown to have an indirect association with bullying victimization, which was mediated by difficulty making friends. In addition, adolescents' difficulty making friends was positively associated with bullying victimization. Practitioners working with adolescents with physical disabilities are encouraged to foster collaborative processes across various ecological systems of the adolescent and family to address caregivers' frustration and promote positive social and emotional development of the adolescent with physical disabilities, which can decrease their risk of bullying victimization.

Social Camouflaging in Autistic and Neurotypical Adolescents: A Pilot Study of Differences by Sex and Diagnosis.

Camouflaging is a process through which individuals mask autistic traits. Studies suggest autistic females may camouflage more than autistic males. However, research has focused on adults and includes few comparisons between autistic and neurotypical individuals. This study compared levels of camouflaging by sex and diagnosis in autistic and neurotypical adolescents. Females reported higher overall levels of camouflaging when not accounting for age. When accounting for age, an age by diagnosis interaction effect emerged. This possible effect of age on camouflaging has implications for understanding how camouflaging behaviors develop and warrants further exploration. Differences also emerged on behaviors labeled as masking and assimilation, subcomponents of camouflaging, with females appearing more similar to their neurotypical peers on behaviors related to social awareness.

Exploring the Capabilities of Harmony for Upper-Limb Stroke Therapy.

Harmony is a bimanual upper-limb exoskeleton designed for post-stroke rehabilitation. It moves the subject's shoulders and arms through their entire ranges of motion while maintaining natural coordination, is capable of force/torque control of each joint, and is equipped with sensors to measure motions and interaction forces. With these capabilities Harmony has the potential to assess motor function and create individualized therapy regimens. As a first step, five stroke survivors underwent rehabilitation sessions practicing multijoint movements with the device. Each participant performed a total of 1130 motions over seven hours of therapy with no adverse effects reported by participants or the attending therapist, supporting the suitability of Harmony for use in a clinical setting. Donning and doffing time averaged 3.5 minutes and decreased with therapist experience. Reported levels of stress, anxiety, and pain indicate that the Harmony safely assisted in the completion of the trained movements and has great potential to motivate and engage patients. We developed a novel methodology for assessing coordination capability and results from the study indicate that Harmony can enable therapists to identify neuromuscular weakness and maladaptive coordination patterns and develop targeted interventions to address these aspects of upper-limb function. The results suggest Harmony's feasibility and show promising improvements, motivating future study to gain statistical support.

The Milwaukee Youth Belongingness Scale (MYBS): Development and validation of the scale utilizing item response theory.

The examination of belonging in schools, connecting school belonging to a plethora of academic and psychosocial outcomes, has been well established in the literature. Researchers have measured school belonging most frequently with the Psychological Sense of School Membership, but its psychometric properties have been called into question by several researchers. Further, the scale measures 1 subset of belonging (i.e., school), leaving out powerful belonging connections in other areas of a student's life, namely peers and family. The current study examines the development and validation of the Milwaukee Youth Belongingness Scale. This process was examined by utilizing item response theory and a secondary analysis confirming the factor structure and the validation of the scale by comparing it to other constructs. The results confirm a 9-item scale that involves a total scale score and 3 factors (School, Peers, Family). Implications for mental health professionals and future research are discussed.

Assessing Wrist Movement With Robotic Devices.

Robotic devices have been proposed to meet the rising need for high intensity, long duration, and goal-oriented therapy required to regain motor function after neurological injury. Complementing this application, exoskeletons can augment traditional clinical assessments through precise, repeatable measurements of joint angles and movement quality. These measures assume that exoskeletons are making accurate joint measurements with a negligible effect on movement. For the coupled and coordinated joints of the wrist and hand, the validity of these two assumptions cannot be established by characterizing the device in isolation. To examine these assumptions, we conducted three user-in-the-loop experiments with able-bodied participants. First, we compared robotic measurements to an accepted modality to determine the validity of joint- and trajectory-level measurements. Then, we compared those movements to movements without the device to investigate the effects of device dynamic properties on wrist movement characteristics. Last, we investigated the effect of the device on coordination with a redundant, coordinated pointing task with the wrist and hand. For all experiments, smoothness characteristics were preserved in the robotic kinematic measurement and only marginally impacted by robot dynamics, validating the exoskeletons for use as assessment devices. Stemming from these results, we propose design guidelines for exoskeletal assessment devices.

Maintaining subject engagement during robotic rehabilitation with a minimal assist-as-needed (mAAN) controller.

One challenge of robotic rehabilitation interventions is devising ways to encourage and maintain high levels of subject involvement over long duration therapy sessions. Assist-as-needed controllers have been proposed which modulate robot intervention in movements based on measurements of subject involvement. This paper presents a minimal assist-as-needed controller, which modulates allowable error bounds and robot intervention based on sensorless force measurement accomplished through a nonlinear disturbance observer. While similar algorithms have been validated using healthy subjects, this paper presents a validation of the proposed mAAN control algorithm's ability to encourage user involvement with an impaired individual. User involvement is inferred from muscle activation, measured via surface electromyography (EMG). Experimental validation shows increased EMG muscle activation when using the proposed mAAN algorithm compared to non-adaptive algorithms.

Design and characterization of the OpenWrist: A robotic wrist exoskeleton for coordinated hand-wrist rehabilitation.

Robotic devices have been clinically verified for use in long duration and high intensity rehabilitation needed for motor recovery after neurological injury. Targeted and coordinated hand and wrist therapy, often overlooked in rehabilitation robotics, is required to regain the ability to perform activities of daily living. To this end, a new coupled hand-wrist exoskeleton has been designed. This paper details the design of the wrist module and several human-related considerations made to maximize its potential as a coordinated hand-wrist device. The serial wrist mechanism has been engineered to facilitate donning and doffing for impaired subjects and to insure compatibility with the hand module in virtual and assisted grasping tasks. Several other practical requirements have also been addressed, including device ergonomics, clinician-friendliness, and ambidextrous reconfigurability. The wrist module's capabilities as a rehabilitation device are quantified experimentally in terms of functional workspace and dynamic properties. Specifically, the device possesses favorable performance in terms of range of motion, torque output, friction, and closed-loop position bandwidth when compared with existing devices. The presented wrist module's performance and operational considerations support its use in a wide range of future clinical investigations.

Estimating anatomical wrist joint motion with a robotic exoskeleton.

Robotic exoskeletons can provide the high intensity, long duration targeted therapeutic interventions required for regaining motor function lost as a result of neurological injury. Quantitative measurements by exoskeletons have been proposed as measures of rehabilitative outcomes. Exoskeletons, in contrast to end effector designs, have the potential to provide a direct mapping between human and robot joints. This mapping rests on the assumption that anatomical axes and robot axes are aligned well, and that movement within the exoskeleton is negligible. These assumptions hold well for simple one degree-of-freedom joints, but may not be valid for multi-articular joints with unique musculoskeletal properties such as the wrist. This paper presents an experiment comparing robot joint kinematic measurements from an exoskeleton to anatomical joint angles measured with a motion capture system. Joint-space position measurements and task-space smoothness metrics were compared between the two measurement modalities. The experimental results quantify the error between joint-level position measurements, and show that exoskeleton kinematic measurements preserve smoothness characteristics found in anatomical measures of wrist movements.

Virtual Environments, Online Racial Discrimination, and Adjustment among a Diverse, School-Based Sample of Adolescents.

Given the recent rise in online hate activity and the increased amount of time adolescents spend with media, more research is needed on their experiences with racial discrimination in virtual environments. This cross-sectional study examines the association between amount of time spent online, traditional and online racial discrimination and adolescent adjustment, including depressive symptoms, anxiety and externalizing behaviors. The study also explores the role that social identities, including race and gender, play in these associations. Online surveys were administered to 627 sixth through twelfth graders in K-8, middle and high schools. Multiple regression results revealed that discrimination online was associated with all three outcome variables. Additionally, a significant interaction between online discrimination by time online was found for externalizing behaviors indicating that increased time online and higher levels of online discrimination are associated with more problem behavior. This study highlights the need for clinicians, educational professionals and researchers to attend to race-related experiences online as well as in traditional environments.

Peer reactions to early childhood aggression in a preschool setting: Defenders, encouragers, or neutral bystander.

PURPOSE: The purpose of the current study was to determine if peer reactions to aggression among preschool youth were consistent with those conceptualized in the adolescent bullying literature as defenders, encouragers, and neutral bystanders. RESEARCH DESIGN: Direct observations were used to document patterns for types of peer-directed aggression in early childhood settings to ascertain interaction differences between individuals involved within the bullying dynamic. METHODS AND PROCEDURES: Observations of 50 students in preschool were conducted over 5.5 months. Event recording procedures were used to document aggressive behaviors and reactions from peers and teachers. RESULTS: Results indicated that the majority of aggression was physical. Additionally, peer reactions, as described in the bullying literature for school-aged youth, occurred very infrequently. CONCLUSION: Peer aggression tended to be more physical, suggesting that early childhood educators should attend to these physical interactions, and cultivate a classroom community that emphasizes social supports and appropriate interactions.

Longitudinal Associations Between Cybervictimization and Mental Health Among U.S. Adolescents.

PURPOSE: An emerging body of literature suggests that victims of bullying report detrimental mental health outcomes, such as depression and anxiety. The purpose of this study was to explore the relationship between cybervictimization, depression, and anxiety among school-aged youth over a 3-year time frame. METHODS: Students in Grades 6 through 12 at the initial wave of the study responded to survey items designed to assess their online experiences, including cybervictimization and self-reported depression and anxiety at three separate time points, over a 3-year period. In total, 559 school-aged youth participated in the study. RESULTS: Results suggest a reciprocal relationship between cybervictimization and depression and cybervictimization and anxiety. More specifically, depression at Time 1 predicted cybervictimization at Time 2, depression at Time 2 predicted cybervictimization at Time 3, and cybervictimization at Time 1 predicted depression at Time 3. Additionally, cybervictimization at Time 1 predicted anxiety at Time 2, cybervictimization at Time 2 predicted anxiety at Time 3, and anxiety at Time 1 predicted cybervictimization at Time 2. CONCLUSIONS: Based on the findings from this study, cybervictimization, depression, and anxiety seem to have a reciprocal relationship. Therefore, educational and mental health professionals should consider interventions that address adolescents' online experiences, while supporting mental health and social and emotional learning.

Bullying and middle school students with and without specific learning disabilities: an examination of social-ecological predictors.

The current study investigated demographic variables, sense of belonging, and social supports as predictors for involvement in bullying for students with specific learning disabilities (SLD) and students without disabilities. Although these student groups are characteristically different, results suggested involvement in bullying was invariant. However, gender, race, grade point average, and participation in extracurricular activities emerged as significant predictors for involvement in the bullying dynamic. In addition, increased peer social support was found to be the most significant predictor of decreased bullying, victimization, fighting, and anger for both students with SLD and students without disabilities. Educational implications include the suggestion that schools adopt multitiered antibullying programs that foster increased social supports and peer acceptance and incorporate targeted interventions for at-risk subpopulations of students.

System Characterization of MAHI EXO-II: A Robotic Exoskeleton for Upper Extremity Rehabilitation.

This paper presents the performance characterization of the MAHI Exo-II, an upper extremity exoskeleton for stroke and spinal cord injury (SCI) rehabilitation, as a means to validate its clinical implementation and to provide depth to the literature on the performance characteristics of upper extremity exoskeletons. Individuals with disabilities arising from stroke and SCI need rehabilitation of the elbow, forearm, and wrist to restore the ability to independently perform activities of daily living (ADL). Robotic rehabilitation has been proposed to address the need for high intensity, long duration therapy and has shown promising results for upper limb proximal joints. However, upper limb distal joints have historically not benefitted from the same focus. The MAHI Exo-II, designed to address this shortcoming, has undergone a static and dynamic performance characterization, which shows that it exhibits the requisite qualities for a rehabilitation robot and is comparable to other state-of-the-art designs.

System characterization of RiceWrist-S: a forearm-wrist exoskeleton for upper extremity rehabilitation.

Rehabilitation of the distal joints of the upper extremities is crucial to restore the ability to perform activities of daily living to patients with neurological lesions resulting from stroke or spinal cord injury. Robotic rehabilitation has been identified as a promising new solution, however, much of the existing technology in this field is focused on the more proximal joints of the upper arm. A recently presented device, the RiceWrist-S, focuses on the rehabilitation of the forearm and wrist, and has undergone a few important design changes. This paper first addresses the design improvements achieved in the recent design iteration, and then presents the system characterization of the new device. We show that the RiceWrist-S has capabilities beyond other existing devices, and exhibits favorable system characteristics as a rehabilitation device, in particular torque output, range of motion, closed loop position performance, and high spatial resolution.
