Serotonin transporter 5-HTTLPR genotype is associated with intrusion and avoidance symptoms of DSM-5 posttraumatic stress disorder (PTSD) in Chinese earthquake survivors

Background and Objectives: Prior studies have found that the serotonin transporter gene-linked polymorphic region (5-HTTLPR) interacts with trauma exposure to increase general risk for Posttraumatic Stress Disorder (PTSD). However, there is little knowledge about the effects of the interaction on distinct symptom clusters of PTSD. This study aimed to investigate the relation between the interaction of 5-HTTLPR and earthquake-related exposures and a contemporary phenotypic model of DSM-5 PTSD symptoms in a traumatised adult sample from China.

Design: A cross-sectional design with gene-environment interaction (G?×?E) approach was adopted. Methods: Participants were 1131 survivors who experienced 2008 Wenchuan earthquake. PTSD symptoms were assessed with the PTSD Checklist for DSM-5 (PCL-5). The 5-HTTLPR polymorphism was genotyped with capillary electrophoresis (CE) in ABI 3730xl genetic Analyzer.

Results: Although there was no significant interaction between 5-HTTLPR and traumatic exposure on total PTSD symptoms, respondents with the LL genotype of 5-HTTLPR who were highly exposed to the earthquake experienced lower intrusion and avoidance symptoms than those with the S-allele carriers.

Conclusions: The findings suggest that the 5-HTTLPR may have an important impact on the development of PTSD and add to the extant knowledge on understanding and treating of posttraumatic psychopathology.     

Benefits of team participative decision making and its potential to affect individual creativity

How does team participative decision‐making affect individual creative performance? Building on team climate theory (Anderson & West, 1998; West 1990, 2002; West & Sacramento, 2012), this study investigates the indirect effect of team participative decision making on employee creativity through individual perception of cognition team diversity and psychological safety. Results from 256 supervisor–subordinate dyads in 45 teams show that team participative decision making is positively associated with cognitive team diversity and psychological safety. For the mediating effects, team participative decision‐making climate is positively indirectly related to creative performance via psychological safety but not via cognitive team diversity. Theoretical and practical implications are discussed.     

Development and Initial Validation of a Scale Measuring the Beliefs of Educators Regarding Response to Intervention

This article presents information on the development and initial validation of the 16-item Response to Intervention (RTI) Beliefs Scale. The scale is designed to measure the extent to which educators working in schools hold beliefs consistent with the tenets of RTI. The authors administered the instrument to 2,430 educators in 62 elementary schools in the fall of 2007 and 2,443 educators in 68 elementary schools in the spring of 2008. Exploratory, single-level confirmatory, and multilevel confirmatory factor analysis procedures were used to examine construct validity. Results supported a correlated 3-factor model (Academic Abilities and Performance of Students with Disabilities, Data-Based Decision Making, and Functions of Core and Supplemental Instruction) at both the school and educator levels of analysis. Furthermore, the factor scores derived from the model demonstrated significant, positive relations to RTI implementation. Reliability estimates for two of the three factor scores exceeded.70. Implications for research on educator beliefs and implementation of RTI as well as implications for school psychologists supporting RTI implementation are discussed.

系统性综述干细胞来源的生物材料采集的供者健康风险

通过检索国内外6个文献数据库以获取发表于2010年1月~2020年7月研究相关的文献,并对干细胞来源的生物材料采集的供者健康风险进行了系统性综述。50篇相关文献分析显示,在许多情况下,生物材料采集可使供者承受健康风险,包括麻醉、粒细胞集落刺激因子或促排卵药物使用、中心静脉导管放置、穿刺等带来的风险。此外,生物材料采集还可影响供者的心理健康。根据上述发现,建议干细胞来源的生物材料采集需要严格的伦理管控,以保障生物材料供者的健康权益。

Bi-Directional Relationship Between Self-Regulation and Improved Eating: Temporal Associations With Exercise,Reduced Fatigue,and Weight Loss

ABSTRACT. Severely obese men and women (body mass index ≥ 35 ≤ 55 kg/m²; M_age = 44.8 years, SD = 9.3) were randomly assigned to a 6-month physical activity support treatment paired with either nutrition education (n = 83) or cognitive-behavioral nutrition (n = 82) methods for weight loss. Both groups had significant improvements in physical activity, fatigue, self-regulation for eating, and fruit and vegetable intake. Compared to those in the nutrition education group, participants in the behavioral group demonstrated greater overall increases in fruit and vegetable intake and physical activity. These group differences were associated with changes that occurred after Month 3. Increased physical activity predicted reduced fatigue, β = ?.19, p =.01. A reciprocal relationship between the mediators of that relationship, which were changes in self-regulation and fruit and vegetable intake, was identified. There was significantly greater weight loss over six months in the behavioral nutrition group when contrasted with the nutrition education group. Self-regulation for eating and fruit and vegetable intake were significant predictors of weight loss over both three and six months. Findings enabled a better understanding of psychosocial effects on temporal aspects of weight loss and may lead to more effective behavioral treatments for weight loss.
