Effect of Beni-Koji on Blood Pressure and Learning Behavior in Spontaneously Hypertensive Rats

1)紅麹投与群は米粉を投与した対照群と比べ､体重増加に対しては有意な差は認められなかった｡ 2)紅麹投与群は対照群と比べ2週目より有意な血圧下降作用が認められた｡ 3)紅麹投与群は､対照群に比べ総エラー数および参照記憶エラー数の減少､すなわち学習獲得能が高いことが判明した｡ 4)以上の成績より､紅麹の投与により生じた血圧下降が二次的に学習獲得能を上昇させたのではないかと考えられる

Moderating Effect of Agreeableness on Coping Among Cancer Survivors: A Longitudinal Analysis

The current study examined interactions among Agreeableness, problem-focused coping (PFC), and emotional expression in predicting purpose in life and self-acceptance. The sample included 345 cancer survivors, who participated in the National Survey of Midlife Development in the United States (MIDUS) studies II and III. We found three-way interactions after statistically controlling for sex, age, level of educational attainment, years since cancer diagnosis, previous levels of purpose in life and self-acceptance, and the Big Five personality traits. Results indicate that, depending on the levels of Agreeableness, the effect of utilizing PFC and emotional expression after a cancer may vary

Influence of community-level factors on relation between community resilience and posttraumatic growth.

The current study aimed at exploring the influence of individual- and community-level factors on posttraumatic growth (PTG) after Hurricane Harvey and whether the community-level factors moderate the relation between perceived community resilience and PTG. Final participants were 415 adults who reported directly experiencing Hurricane Harvey, which made landfall on August 26, 2017. Data collection occurred approximately 16 months after the hurricane. Perceived community resilience and household income were significantly associated with PTG. There was a marginally significant cross-level interaction effect between perceived community resilience and median household income on PTG. The current study raises an important implication of economic development on facilitating PTG. (PsycInfo Database Record (c) 2020 APA, all rights reserved

Association Between Daily Rumination and Posttraumatic Growth During the COVID-19 Pandemic: An Experience Sampling Method

Objective: The current intensive longitudinal study aimed at examining the association between daily rumination (i.e., intrusive rumination and deliberate rumination) and posttraumatic growth (PTG) associated with the pandemic of coronavirus disease 2019 (COVID-19). Method: Final participants were 71 adults who were recruited from Amazon’s Mechanical Turk. Participants responded to daily questions regarding ruminations they engaged in and PTG they experienced that day for a total of 29 days. Results: As expected, there was no significant association between intrusive rumination and PTG, but a significant positive association was found between deliberate rumination and PTG. In addition, a person of color and those who reported as religious experienced higher levels of PTG. Furthermore, there was a significant between-person variability on the effect of deliberate rumination on PTG. Conclusions: The current study supports previous findings between rumination and PTG. It also raises the importance of acknowledging that the levels of one’s PTG following deliberate rumination may differ greatly from the typical individual, indicating the need to be mindful of individual experience

Examining reciprocal influence between posttraumatic stress and depressive symptoms among natural disaster survivors

Background: The current study examined reciprocal effects of symptoms of posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) among individuals affected by Hurricane Ike, which made landfall on September 13, 2008 Methods: Participants were 658 survivors, who participated in the Galveston Bay Recovery Study (GBRS; National Center for Disaster Mental Health Research, Galea, and Norris, 2016). Assessment was conducted at 3, 6, and 15 months after the disaster. Bivariate latent change score modeling was conducted to examine the nature of the time-sequential associations between symptoms of PTSD and MDD Results: Results revealed a unidirectional coupling effect from depression to change in PTSD, but unidirectional coupling effect from PTSD to change in depression was not supported. Limitations: Only linear relations of within-individual change and time-sequential associations between PTSD and depression were examined, and therefore, it precludes potential nonlinear relations between these constructs. Also, the results of the current study are limited to the studied timespan (i.e., 3 to 15 months). Lastly, other factors that could be confounding the change in PTSD symptoms were not examined, leaving a possibility of other constructs that may influence the change in future PTSD symptoms Conclusions: The current study suggests that disaster survivors with higher symptoms of depression may be at higher risk of experiencing increased PTSD symptoms even after one year, raising an importance of tailoring a treatment to alleviate depressive symptoms and to mitigate the risk of future symptoms of PTS

Reciprocal influence between posttraumatic stress and posttraumatic growth approximately one year after hurricane harvey: A bivariate latent change score modeling approach

The current study examined reciprocal effects of posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) at 16, 17, and 19 months after Hurricane Harvey. The final sample included 443 adults who were physically residing in the area when Hurricane Harvey made landfall on August 26, 2017. Bivariate latent change score modeling was conducted to examine the nature of the time-sequential associations between PTSS and PTG. A result from the latent change score modeling revealed a unidirectional coupling effect from PTG to change in PTSS, indicating that individuals with higher levels of PTG were more likely to experience decreased prevalence of PTSS. However, the unidirectional coupling effect from PTSS to change in PTG was not supported. The current study suggests that disaster survivors with higher levels of PTG may experience decreased prevalence of PTSS, raising the importance of tailoring a treatment incorporating PTG to alleviate future PTSS
