童年及当前环境压力对跨期选择的影响:时间感知的中介作用

本文分别以90名和70名大学生为被试,通过问卷调查和实验任务的方式,探究童年环境、当前环境压力、时间感知和跨期选择四者之间的关系。结果表明:(1)童年环境影响时间感知,相比童年社会经济地位高的个体,童年社会经济地位低的个体更倾向于高估时距。(2)在正常环境下,个体时间感知完全中介作用于童年环境和跨期选择之间的关系,童年环境通过影响个体时间感知进而影响个体的跨期选择。(3)在当前环境压力下,时间感知并未起到中介作用。研究表明,时间感知在童年压力与在当前环境压力条件下,对跨期选择的影响作用不同。     

童年期不良经历对中学生良心的影响：特质自我控制和自我损耗的链式中介作用

为探讨童年期不良经历对中学生良心的影响及作用机制,基于生物生态学理论和自我控制资源模型,采用整群取样法抽取湖南省7所城市7所中学初一到高三学生共3648名,使用童年期不良经历问卷、青少年良心问卷、特质自我控制量表和自我调节疲劳量表进行问卷调查。结果发现:(1)童年期不良经历负向预测中学生良心;(2)特质自我控制和自我损耗在童年期不良经历和中学生良心间起部分中介作用;(3)特质自我控制和自我损耗在童年期不良经历和中学生良心间起链式中介作用。研究结果表明,童年期不良经历不仅是影响中学生良心的重要外部因素,而且还会通过影响特质自我控制和经由自我损耗对中学生良心产生间接作用;减少和避免童年期不良经历对中学生心理的冲击,提升其特质自我控制水平,降低其自我损耗,是预防中学生良心失守和提升良心水平的重要途径。     

儿童期创伤与有留守经历大学生负性情绪：心理韧性的调节作用

本研究旨在考察有留守经历的大学生儿童期创伤与负性情绪关系,以及心理韧性在其间的调节作用。对391名有留守经历的大学生进行间隔3个月的两次问卷调查。结果:(1)相较于没有儿童期创伤的个体,有儿童期创伤的个体心理韧性更低,抑郁、焦虑、压力水平更高;(2)在控制性别、城乡来源、是否独生、年龄与T1时间点负性情绪的作用后,T1时间点的儿童期创伤、心理韧性均能显著预测T2时间点的负性情绪;(3)低心理韧性水平下,儿童期创伤显著预测留守经历大学生的负性情绪;高心理韧性水平下,预测作用不再显著。表明儿童期创伤是有留守经历的大学生负性情绪的风险因素,心理韧性可以调节儿童期创伤对有留守经历大学生的负性情绪的预测。     

Primary school teacher outcomes from online professional development for physical literacy: A randomised controlled trial

IntroductionPrimary (or elementary) school teachers are often relied upon to provide children with opportunities for physical literacy development; however, many of these teachers feel they lack the skills to effectively promote or ‘teach’ physical literacy. We examined the effects of an online physical literacy professional development program—relative to receiving widely-available online resources or continuing with ‘normal’ practice—on primary school teachers’ physical literacy knowledge and application.MethodsA parallel three-arm randomised controlled trial in which 92 primary school teachers were assigned to (a) an online professional development program designed to support teachers’ physical literacy instructional skills (‘intervention’), (b) receive widely-available online physical literacy resources (‘comparison’), or (c) a typical practice ‘control’ condition. Data were collected at baseline and following the four-week intervention period. The primary outcome was teachers’ physical literacy knowledge and application; secondary outcomes included teachers’ self-reported perceptions of confidence, values, and barriers. Between-group differences were assessed using the intention-to-treat principle with analysis of covariance accounting for demographic factors and baseline differences in the focal outcome.ResultsTeachers in the intervention arm scored significantly higher on post-intervention physical literacy knowledge and application than their counterparts in both the control (d = .47, p = .044) and comparison (d = 0.87, p = .007) arms. This pattern of differences was also observed for teachers’ value of physical literacy, autonomy support, and perceived personal barriers.ConclusionTo the best of our knowledge, this is the first adequately powered randomised controlled trial to demonstrate improvements in physical literacy instructional outcomes as a result of primary school teacher participation in targeted online professional development.     

A longitudinal analysis of reciprocal relationships between actual and perceived motor competencies and physical self-concept in primary-school age children

Physical self-concept (PSC) and motor competencies are important factors in view of the development of a physically active lifestyle. There are research gaps regarding longitudinal studies of these relationships. This article presents findings of a longitudinal study (n = 200; 58% girls, M = 8.84 ± 0.63 years) at three primary schools. The aim of this study was to analyze the relationship between actual motor competencies (AMC) and perceived motor competencies (PMC) and PSC. Therefore, manifest path models in cross-lagged design were performed. Results show that correlations between PMC and AMC increased over time and were stronger in object control than in locomotor. Effects of AMC on PSC were more strongly mediated by PMC in object control than in locomotor. To promote physical activity, developing strategies should be aimed at the acquisition of AMC, particularly in object control, and PMC, especially in locomotor, during childhood.     

心理社会因素在糖尿病发病及其干预中的作用

近年来,全球糖尿病患病率逐年上升,并成为继肿瘤、心脑血管疾病后第三大严重危害人类健康的疾病。本文从生物-心理-社会医学角度出发,通过查阅并汇总文献,论述了糖尿病对现代人生活质量的影响,并探究了影响糖尿病的各种心理社会因素,最后提出了三种防治糖尿病的心理干预措施。     

35岁～64岁糖尿病患者1O年内心肌梗死＼中风发病和死亡危险评估

应用《未来10年内心肌梗死、中风发病和死亡危险的科学预测量表》,对某社区335例35岁～64岁糖尿病患者进行了评估。结果显示,35岁～64岁糖尿病人群未来10年内严重心血管事件发生风险甚高,对可逆危险因素的评估和调整刻不容缓。     

妊娠期糖尿病管理策略

妊娠期糖尿病(gestational diabetes mellitus,GDM)是指妊娠期发生或首次发现的不同程度的糖代谢异常。未加控制的妊娠期高血糖可对母子产生极大的围产期和远期危害。妊娠后糖代谢发生明显变化妊娠期血糖的管理和控制与非孕期不同。GDM一经确诊,应及时干预,加强母儿监测,控制妊娠期血糖,以降低母儿并发症,改善围生儿结局;产后对母儿严密随访,异常者给予相应处理,以减少或延缓产妇在产后发展为成为2型糖尿病的可能及预防子代发生肥胖、高血压、糖尿病等代谢综合征的发生。     

Childhood trauma and psychosis: Review of the evidence and directions for psychological interventions

There is controversy over whether childhood trauma (CT) is a causal risk factor for psychosis. The aim of this study was to provide psychologists with a brief overview of the research into relationship between childhood trauma and psychosis and directions for psychological interventions. It details six of the highest quality studies in the area and tentatively concludes from these that there is evidence for a relationship between CT and psychosis. Hallucinations and delusions have been implicated as important factors in the relationship between CT and psychotic disorder and these are discussed, along with post‐traumatic intrusions and schemas, which have been conceptualised as part of the psychological mechanisms whereby CT confers a risk for psychosis. The development of psychological interventions for people with psychosis who have experienced CT is in its infancy but has been based on evidence‐based cognitive behavioural interventions in psychosis and post‐traumatic stress disorder. A formulation‐based approach is described in this paper, along with a case study.     

Internet-based contingency management to improve adherence with blood glucose testing recommendations for teens with type 1 diabetes

The current study used Internet-based contingency management (CM) to increase adherence with blood glucose testing to at least 4 times daily. Four teens diagnosed with Type 1 diabetes earned vouchers for submitting blood glucose testing videos over a Web site. Participants submitted a mean of 1.7 and 3.1 blood glucose tests per day during the 2 baseline conditions, respectively, compared to 5.7 tests per day during the intervention. Participants and their guardians rated the program favorably on a number of dimensions. The results suggest that Internet-based CM is feasible, acceptable, and effective to increase self-monitoring of blood glucose in teens.
