Can a before-school physical activity program decrease bullying victimization in disadvantaged children? The Active-Start Study

Background/ObjectiveTo test the effectiveness of an 8-week before-school physical activity program to reduce bullying victimization among a group of socially disadvantaged children in the Active-Start study.MethodA non-blinded randomized controlled trial was conducted in three public schools classified as highly vulnerable and located in a deprived area of Santiago (Chile). A total of 5 classes participated, totaling 170 fourth grade children. The intervention was delivered before starting the first school-class (8:00–8:30 a.m.). The program lasted for 8 weeks. Primary outcome measurement on bullying victimization was assessed by the CUBE questionnaire at baseline and post-intervention.ResultsThere was a statistically significant reduction in the probability of suffering physical bullying (OR= 0.18, 95% CI, 0.04-0.82; p= .027) and verbal bullying (OR=0.13, 95% CI, 0.02-0.97; p= .046) after the 8-week program.ConclusionsParticipation in an 8-week before-school physical activity intervention implemented in schools located in a disadvantaged district in Santiago (Chile) resulted in lower levels of bullying victimization among study participants. The Active-Start program may be a feasible and potentially scalable intervention option to improve the climate and pro-sociality environment at schools.     

Does experienced pain affects local brain volumes? Insights from a clinical acute pain model

Background/Objective:To study pain-brain morphometry associations as a function of post-surgery stages (anesthesia, pain and analgesia) in an acute pain model. Method:Impacted mandible third molar were extracted. Before surgery, an anatomical T1 scan was obtained. Regional brain volumen and subcortical nuclei shapes were obtained. Statistical analyses were done using multiple regression, being pain scores the predictors and voxel volumes, subcortical nuclei volumes and subcortical nuclei shapes, the outcomes. Results:Pain was significantly larger at pain than at anesthesia and analgesia stages, and was higher during anesthesia than during analgesia. Pain intensity was related to grey matter in several cortical (Insula, Mid Frontal and Temporal Gyruses, Precuneus, Anterior Cingulate), and subcortical nuclei (Hippocampus, Thalamus, Putamen, Amygdala), depending of the post-surgical stage. A larger number of brain areas showed significance at pain that at anesthesia and analgesia stages. Conclusions:The relationships of regional brain volumes and subcortical nuclei shapes with pain scores seemed to be unsteady, as they changed with the patient's actual pain stage.     

学校氛围与青少年学校适应：一项追踪研究

通过对709名青少年进行追踪研究,分别以青少年自我报告与教师评价的方式测查了学校氛围与学校适应,主要探讨学校氛围与青少年学校适应的长期预测关系,以及性别在二者间的调节效应.结果表明:(1)青少年第一年感知到的学校氛围能预测其第二年、第三年的适应问题和适应能力,第二年感知到的学校氛围能预测其第三年的适应能力和学业成绩;(2)青少年感知到的自主机会对其学校适应有负面作用;(3)教师支持和同学支持对青少年学校适应具有积极作用,但同学支持的作用会随着在校时间的增加而发生逆转,即第一年的同学支持负向预测第二年的学习问题和第三年的学业成绩,正向预测第三年的适应能力,而第二年的同学支持则对第三年的适应能力和学业成绩均有负向预测作用;(4)女生的学校适应普遍好于男生,性别对学校氛围与青少年学校适应之间的关系具有部分调节作用.     

School Sense of Community,Teacher Support,and Students’ School Safety Perceptions

This study examined the association between two characteristics of school climate (sense of community and teacher support, measured both at the individual and at the school level) and students’ feelings of being unsafe at school. The study involved a sample of 49,638 students aged 10–18 years who participated in the 2010–2012 California Healthy Kids Survey. Using hierarchical linear modeling (HLM), our findings revealed that, at the individual level, students perceiving higher levels of sense of community and teacher support at school were less likely to feel unsafe within the school environment. At the school level, sense of community was negatively associated with unsafe feelings, whereas there was no association between school‐level teacher support and feelings of being unsafe at school.     

The amount of recent action-outcome coupling modulates the mechanisms of the intentional binding effect: A behavioral and ERP study

Our everyday interactions depend on the ability to maintain a feeling of control over our bodily actions, that is, the sense of agency. The intentional binding effect – a perceived temporal shortening between voluntary actions and sensory outcomes – has been shown to implicitly measure agency. We investigated the effect’s underlying mechanisms: prediction and retrospective inference. First, long-term and recent action-outcome coupling were compared. Second, brain activity was recorded to uncover the neural correlates of the two mechanisms. Our results show that the recent accumulation of action-outcome coupling, but not that of a long-term accumulation, is correlated with the binding effect of actions and accounts for both mechanisms. Temporal action binding was reflected in both the readiness potential and the auditory evoked potential. The results shed new light on our understanding of the influence that immediate context of an action has on its temporal binding and the neural substrate of human agency.     

Antecedents and outcomes of intervention program participation and task priority change among school psychology counselors: A latent variable growth framework

A three-year national intervention program introduced into the School Psychology Service (SPS) in Norway with the aim of increasing systemic level work among SP counselors was investigated. Latent variable growth models based on longitudinal data from 195 SP counselors gave no significant mean level change in systemic level work. This concurred with GLM analyses based on data from a sample of 20 schools. However, retrospective self-reported significant positive mean level change for systemic level work was detected among the SP counselors. Intervention program participation was associated with individual change in systemic level work. Self-efficacy beliefs about systemic level work, and school-related etiology beliefs predicted individual change to a certain degree. Comparison of two rival models gave no support for a hypothesized interaction among intervention program participation and beliefs in their effects on systemic level work. Open-ended questions indicated that individual level workload and the perceived expectations from the schools may have concern for a successful effect of the intervention program in addition to the hypothesized ones. Individual change in systemic level work was positively associated with individual change in job satisfaction.     

Counselor perceptions of students who vary in gender and socioeconomic status

The present study experimentally examined how counselor perceptions of hypothetical students are affected by student gender and socioeconomic status (SES). Results showed that counselors perceive students from low SES backgrounds as having less promising futures and lower math abilities. Counselors also rated female students as lower in math abilities than male students. Our results indicate that institutions should consider providing more school counselor training to reduce bias based on gender and SES.

A consequence of school grade labels: preservice teachers’ interpretations and recall of children’s classroom behavior

This study investigated whether preservice teachers’ attitudes surrounding school grade labels influenced interpretations and recall of children’s classroom behavior using the automatic attitude activation model (Fazio, In R. M. Sorrentino & E. T. Higgins (Eds.), Handbook of motivation and cognition: Foundations of social behavior, 1986) as a theoretical framework. Participants were randomly assigned to one of three conditions: The expectation of viewing a video of children in schools labeled as “A,” “F,” or “typical” as a result of the school’s aggregated student performance on standardized tests. Results indicated that participants who believed that they were viewing a video of an “F” classroom recalled more negative and fewer positive behaviors compared to the “typical” classroom. Likewise, there was a trend for participants to recall more negative and fewer positive behaviors when viewing a video of an “F” compared to an “A” school. Therefore, negative attitudes about a school label of “F” biased preservice teachers’ perceptions and memories of children’s classroom behaviors.

Self-esteem,motivation and school attendance among sub-Saharan African girls: A self-determination theory perspective

Sub-Saharan samples are severely under-represented in the psychological literature. Taking an ecological approach, the current study examines key propositions derived from self-determination theory in a sample of adolescent girls in Mozambique. As a framework theory, self-determination theory consists of six sub-theories. We test the main premises of two of these theories: organismic integration theory and basic psychological need theory. In line with organismic integration theory, we assess the role of intrinsic, extrinsic, introjected and identified motivation for school attendance. We also test the possible moderating role of the ecological variable resource scarcity. The second part of the study focuses on the main premise of the basic psychological need sub-theory, which states that satisfaction of the needs for relatedness, competence and autonomy underlies intrinsic motivation, goal-directed behaviour (school attendance) and well-being (self-esteem). The study also assesses the moderation of resource scarcity in these relationships. Results provide support for both sub-theories of self-determination theory. Resource scarcity is not found to moderate the relationships between motivation and attendance or between need satisfaction and well-being, motivation and attendance. Implications for the universality claim of self-determination theory, as well as for the field of international development aid, are discussed.
