Exposure-based Interventions for the management of individuals with high levels of needle fear across the lifespan: a clinical practice guideline and call for further research

Needle fear typically begins in childhood and represents an important health-related issue across the lifespan. Individuals who are highly fearful of needles frequently avoid health care. Although guidance exists for managing needle pain and fear during procedures, the most highly fearful may refuse or abstain from such procedures. The purpose of a clinical practice guideline (CPG) is to provide actionable instruction on the management of a particular health concern; this guidance emerges from a systematic process. Using evidence from a rigorous systematic review interpreted by an expert panel, this CPG provides recommendations on exposure-based interventions for high levels of needle fear in children and adults. The AGREE-II, GRADE, and Cochrane methodologies were used. Exposure-based interventions were included. The included evidence was very low quality on average. Strong recommendations include the following. In vivo (live/in person) exposure-based therapy is recommended (vs. no treatment) for children seven years and older and adults with high levels of needle fear. Non-in vivo (imaginal, computer-based) exposure (vs. no treatment) is recommended for individuals (over seven years of age) who are unwilling to undergo in vivo exposure. Although there were no included trials which examined children < 7 years, exposure-based interventions are discussed as good clinical practice. Implementation considerations are discussed and clinical tools are provided. Utilization of these recommended practices may lead to improved health outcomes due to better health care compliance. Research on the understanding and treatment of high levels of needle fear is urgently needed; specific recommendations are provided.     

Understanding the underlying mechanism of the spacing effect in verbal learning: a case for encoding variability and study-phase retrieval

The spacing effect refers to the mnemonic benefit of spacing repeated study events across time compared to massing (i.e. cramming) repeated study events. Due to the robustness of this finding, substantial research has been devoted to uncovering the spacing effect’s underlying mechanism. Specification of such a mechanism has been guided by consistent findings across methodologies and several experimental manipulations that serve as boundary conditions. Past reviews of the spacing effect literature have generally considered subsets of these factors but never an exhaustive set. Thus, the current review considers more comprehensively six consistent findings in the extant spacing effect literature pertaining to human memory to better discriminate among the previously proposed theories. Review of the literature provides substantial evidence indicating the need for an encoding variability mechanism [e.g. Glenberg, A. M. (1976). Monotonic and nonmonotonic lag effects in paired-associate and recognition memory paradigms. Journal of Verbal Learning and Verbal Behavior, 15, 1–16] in addition to a reminding mechanism [e.g. Benjamin, A. S., &; Tullis, J. G. (2010). What makes distributed practice effective?

高校教师职业心理资本与工作绩效:社会支持的中介效应

用"高校教师职业心理资本量表"、"工作绩效量表"及"社会支持问卷"对来自全国8所高校的718名高校教师进行问卷调查。通过描述性分析、回归及结构方程模型等实证统计方法,深入分析了社会支持、职业心理资本与工作绩效关系模型的理论架构,探究了社会支持在职业心理资本对工作绩效影响的中介模型效应的内在作用机制。研究发现,社会支持、职业心理资本、工作绩效及其各维度之间均存在显著的相关;职业心理资本及其各维度对工作绩效的主效应非常显著;社会支持在职业心理资本及其各维度与工作绩效间的中介效应也均显著。这表明高校教师职业心理资本及各维度对工作绩效不但起着直接的影响作用,而且通过社会支持工作绩效产生了间接的影响。因此,提升高校教师的职业心理资本,建立良好的内、外社会支持系统对提升工作绩效都会形成良好的激励效果,从而实现教师和高校的共同发展。     

A cluster randomized trial to evaluate need-supportive teaching in physical education on physical activity of sixth-grade girls: A mixed method study

ObjectiveThe purpose of this study was to evaluate the efficacy of need-supportive teaching in physical education on girls' daily moderate-to-vigorous physical activity using a mixed method evaluation.Methods507 sixth-grade girls aged 9–14 years of 33 single-sex physical education classes participated in the cluster randomized control trial. During the 16-week intervention period, trained teachers conducted enhanced physical education lessons which were designed based on self-determination theory. In a randomized process, independent researchers using a computer-based algorithm allocated classes to the trial groups (IG n = 19 classes, CG n = 14). These lessons were subject to repeated systematic observations. The students' perceptions of basic psychological need support and satisfaction in physical education were measured using repeated self-report questionnaires. Students' daily moderate-to-vigorous physical activity (MVPA) was assessed by accelerometry. Semi-structured interviews provided a deeper understanding of how purposively sampled focus groups perceived teacher behavior in physical education. After a separate analysis of qualitative and quantitative data, results were merged to investigate the intervention's efficacy and treatment fidelity.FindingsThroughout the school year, the girls' MVPA levels decreased in both groups. Girls who reported their complete physical activity data had a lower body mass index than girls who reported no, or only one or two sets of physical activity data. Results of mixed measures converge on the finding that the teachers in the intervention group provided slightly stronger need support than the control teachers, however, intervention components were not delivered consistently. Therefore, a significant intervention effect on daily MVPA could not be quantified. Autonomy satisfaction significantly predicted MVPA.ConclusionQualitative insights of teaching behavior in PE underlined the importance of need support and revealed structural barriers, which compromised the implementation quality.Trial registrationEthics Committee of the Technical University of Munich 155/16S; Bavarian Ministry of Education IV.8-BO6106/52/12.FundingGerman Research Foundation grant DE2680/3-1.     

The Mediation Effect of Ethical Leadership and Creative Performance: A Social Information Processing Perspective

Drawing upon social information processing theory, the study examined how ethical leadership shapes creative performance. Specifically, we tested a theoretical model integrating the sequential roles of psychological safety and creative self‐efficacy. A two‐waved sample of 512 supervisor‐subordinate dyads from frontline employees of three service industries located in Ghana was administered. The results of the hierarchical linear modeling analysis revealed that there is a positive relationship between ethical leadership and creative performance and that psychological safety positively and significantly mediates the relationship between ethical leadership and creative performance. Similarly, creative self‐efficacy significantly and positively mediates the relationship between ethical leadership and creative performance. Moreover, both psychological safety and creative self‐efficacy sequentially mediate the relationship between ethical leadership and creative performance. We discuss the implications of these results for research and practice.     

Personal and Political: Post-Traumatic Stress Through the Lens of Social Identity,Power, and Politics

Post-traumatic stress disorder (PTSD) has always been controversial and highly politicized. Here, using a social identity approach, we review evidence that trauma and its aftermath are fundamentally linked to social position, sociopolitical capital, and power. We begin this contribution by demonstrating how a person's group memberships (and the social identities they derive from these memberships) are inherently linked to the experience of adversity. We then go on to consider how it is through group memberships that individuals are defined by their trauma risk and trauma histories—that is, a person's group memberships and their trauma are often inherently linked. Considering the importance of group memberships for understanding trauma, we argue that it is important to see these, and group processes more generally, as more than just “demographic” risk factors. Instead, we argue that when groups are defined by their trauma history or risk, their members will often derive some sense of self from this trauma. For this reason, attributes of group memberships are important in developing an understanding of adjustment and adaptation to trauma. In particular, groups' status, their recourse to justice, and the level of trust and solidarity within the group are all central to the impact of traumatic events on individual-level psychological resilience. We review evidence that supports this analysis by focusing on the exacerbating effects of stigma and social mistrust on post-traumatic stress, and the value of solidarity and strong identities for resilience. We conclude that because of these group-related processes, trauma interweaves the personal with the political and that post-traumatic stress is fundamentally about power, positionality, and politics.     

初中生羞怯与手机依赖的关系:一个有调节的中介模型

为探讨初中生羞怯、疏离感、班级心理环境和手机依赖的关系,采用羞怯量表、青少年疏离感量表、班级心理环境量表和手机依赖指数量表对山东省两所学校的1077名初一至初三年级的学生进行调查。结果显示：（1）羞怯显著正向预测初中生手机依赖;（2）疏离感在初中生羞怯与手机依赖之间起完全中介作用;（3）班级心理环境对中介效应的后半段路径起调节作用,高班级心理环境会缓解疏离感对手机依赖的影响,但在极高疏离感水平下,高班级心理环境反而会加剧个体的手机依赖水平。研究有助于了解羞怯对手机依赖的复杂影响机制,对预防以及减少初中生手机依赖具有一定的现实意义。     

Influence of emotional valence on perceived psychological distance depends on emotional intensity

Previous findings regarding the relationship between emotional valence and psychological distance were mixed. The current research examined whether emotional intensity moderates the influence of emotional valence on psychological distance. We manipulated intensity and valence by asking participants to describe a positive or negative event from either a high intensity or low intensity perspective. Studies 1 and 2 revealed that negative events were perceived to be more distant than positive events in the low‐intensity condition in two distinct cultural groups. Study 3 further proved that the obtained patterns were generalizable to different emotions. Finally, Study 4 found that a reduced alert level, but not perceived threats, mediated the interactive effects of valence and intensity on psychological distance. This research highlights the importance of considering the joint effect of different dimensions of emotion, thus advancing the understanding of complex processes of emotion.     

International students’ attachment and psychological well-being: the mediation role of mental toughness

This study examined the relationships of adult attachment, mental toughness (MT), and psychological well-being of international students. We hypothesized that attachment anxiety and avoidance would predict psychological well-being outcome variables and that MT would mediate the attachment-wellbeing links. The participants were 217 international students from a large public college in the United States. Structure Equation Modeling analyses were used to examine the proposed mediation effects. Result showed that MT functioned as a mediator for the paths between attachment anxiety and the two well-being latent variables of psychological distress and life satisfaction. On the other hand, attachment avoidance was found to have a more direct effect on adjustment difficulties without going through MT. Limitation and counseling implications are discussed.     

Positive Psychology Factors as Predictors of Latina/o College Students’ Psychological Grit

Latina/o college students (N = 130) provided perceptions of psychological grit, presence of meaning in life, search for meaning in life, hope, life satisfaction, and mindfulness. Hope and mindfulness were significant predictors of psychological grit. A discussion regarding the importance of these findings and implications for counselors are presented. Un grupo de estudiantes universitarios latinos (N = 130) aportó sus percepciones de perseverancia psicológica, presencia de sentido en la vida, búsqueda de sentido en la vida, esperanza, satisfacción vital y atención plena. Se presenta una discusión sobre la importancia de estos hallazgos y sus implicaciones para los consejeros.
