Exploring trauma exposure and post-traumatic stress in university students of different identity statuses in Lithuania and Japan.

Emerging adulthood is the time when identity questions are addressed. It is also a time of excessive stress and risk for mental health problems. Different identity statuses relate to different mental health outcomes. Yet, little research has addressed how identity status is interlinked with trauma exposure and post-traumatic stress reactions, especially in multicultural contexts. The current study aimed to explore whether different traumatic experiences are related to the current identity status of university students aged between 18 and 29 years and investigate to what extent trauma-exposed emerging adults of different identity statuses report symptoms of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). In total, 2237 university students from Lithuania (n = 791) and Japan (n = 1345) participated in the current study. Identity profiles were revealed by using the Latent Class Analysis approach. Lithuania and Japan were comparable in terms of identity profiles and structure of PTSD/CPTSD. Trauma-exposed emerging adults reported a higher probability of being in troubled diffusion identity status; students in achievement identity status had a lower probability of CPTSD and lower rates of symptoms of disturbances in self-organization. The diffused identity of emerging adults from Lithuania and Japan is associated with trauma exposure, and positive identity is linked with fewer CPTSD reactions.

Trauma exposure, posttraumatic stress, and identity content valences among Japanese adolescents.

INTRODUCTION: Theorists and a few empirical studies have suggested that traumatic experiences, posttraumatic stress disorder (PTSD), and complex PTSD (CPTSD) may affect identity development. However, existing studies have overlooked how adolescents' traumas are associated with the alignment of their identity with socio-cultural expectations, which is a crucial component of identity development. To address this gap, this study examined the associations of various types of potentially traumatic experiences and PTSD and CPTSD symptoms with the positive and negative valences of identity affected by desirable and undesirable images within socio-cultural contexts. METHODS: A cross-sectional survey of 341 adolescents (44.0% girls; Mage = 14.8, SD = 1.8) was conducted in Japan. RESULTS: Exposure to certain types of potentially traumatic events (e.g., family violence and physical attack) were related to high levels of negative identity elements, whereas none of the types were related to positive identity elements. The results also indicated that CPTSD-specific symptoms of disturbances in self-organization (DSO) were related to high levels of negative identity elements rather than PTSD. CONCLUSIONS: The findings expand upon related research by suggesting that adolescents' exposure to some types of traumatic events (e.g., family violence and physical attack) and posttraumatic DSO symptoms have the potential to disturb the alignment of their identities with socio-cultural expectations.

Cross-Cultural Comparison of ICD-11 Adjustment Disorder Prevalence and Its Risk Factors in Japanese and Lithuanian Adolescents.

BACKGROUND: Although there is increasing knowledge about adjustment disorder (AjD) based on the new diagnostic criteria of the International Classification of Diseases (ICD-11), less is known on AjD in adolescents. This study aimed to examine the prevalence of AjD and its risk factors in Japanese and Lithuanian adolescents. METHODS: The cross-sectional study sample comprised 1745 adolescents from Japan (n = 913) and Lithuania (n = 832). AjD was assessed using the Adjustment Disorder New Module-8 (ADNM-8). We compared the prevalence of AjD in Japanese and Lithuanian adolescents. Using multinominal logistic regression analysis, we examined the effects of age, gender, socioeconomic status, and cumulative stressors as societal and cultural factors, resilience as an intrapersonal factor, and loneliness and perceived support as interpersonal factors on adolescent AjD. RESULTS: The prevalence of probable AjD was 11.7% in Lithuanian adolescents and 6.9% in Japanese adolescents. Gender, socioeconomic status, cumulative stressors, resilience, loneliness, and perceived positive social support were each significantly associated with AjD risk. CONCLUSIONS: This cross-cultural comparative study revealed characteristics of the stressors and prevalence of AjD among Japanese and Lithuanian adolescents. In terms of the socio-interpersonal framework model for the stress-response syndrome, sociocultural, intrapersonal, and interpersonal factors were found to be risk factors associated with AjD in adolescents.

Survey and comparison of psychological factors between descendants and non-descendants of survivors of the atomic bomb: Generational differences in mental health indicators.

BACKGROUND: The effects of the atomic bomb experience on survivors and their children have been a topic of human and research interest since early in the postwar era. The topic has centered around knowledge of physical health and studies on germline genetic effects in the second-generation offspring of survivors. However, comparatively little has been done to understand the psychological impact. PURPOSE: The present study focuses on generational factors related to the psychological makeup of second and third generation descendants of atomic bomb survivors. Specifically, this study takes depressive symptoms and factors related to health anxiety into consideration as mental health indicators to offer preliminary evidence that addresses this gap. OBJECTIVE: Data was collected from participants with and without familial affiliation to atomic bomb survivors stratified by age. This resulted in 50 participants that reported having at least one parent who was an atomic bomb survivor categorized as second-generation descendants, 50 participants with at least one grandparent that was an atomic bomb survivor, 50 unrelated participants within an age range of 50-69, and 50 unrelated participants within an age range of 30-49. METHOD: Depressive symptom severity among participants was examined with the Center for Epidemiologic Studies Depression Scale (CES-D), and health anxiety was examined using the Sense of Health Anxiety Scale (SHAS). RESULT: A significant difference was observed for participants without relatives who experienced the atomic bomb such that depressive symptom scores for second generation participants were higher than third generation participants (F (1, 197) = 8.38, p < .01, η2 = 0.04). A between-group difference for third generation participants with and without relatives who experienced the atomic bomb was observed such that third-generation participants with relatives had higher CES-D scores (F (1, 197) = 6.36, p < .01, η2 = 0.03). The levels of health anxiety did not differ between generations with or without relatives of atomic bomb survivors. CONCLUSION: Our findings indicated a difference in depressive symptom tendencies between second and third generation individuals related to atomic bomb survivors. These results suggest that future studies examine the difference in psychological effects between generations as they relate to possible processes that lead to an increase in depressive symptoms.

Promoting Self-Regulatory Management of Chronic Pain Through Dohsa-hou: Single-Case Series of Low-Functioning Hemodialysis Patients.

Hemodialysis patients suffer from long-term pain that drains their energy and contributes to behavioral interference and other negative effects on their daily lives that result in or exacerbate functional limitations. In addition, they deal with dietary restrictions, symptoms such as itching, lack of energy, and psychological stressors like the loss of self-concept and self-esteem. Self-regulation involves the capacity to notice, inform, and modulate responses and behavior, and research indicates that it promotes rehabilitation in chronic pain patients. Research on the aspects of self-regulation afforded by the Japanese psychotherapy Dohsa-hou correspond to psychological processes tied to the sense of self-control that clients realize over their body movements. This study pilot tested a hospital-integrated implementation of Dohsa-hou relaxation tasks as a chronic pain management behavioral intervention for five female hemodialysis patients between the ages of 59-62 years. We conducted an ABABABA single-case design to compare baseline A-phases (treatment-as-usual: TAU) taken at recurring 1 week intervals (three sessions per week for a total of 4 weeks, 12 total recordings) with an intervention of Dohsa-hou B-phases every 4 weeks (three sessions per week for 12 weeks, 36 total recordings) over the span of 4 months to compare effectiveness. Visual Analogue Scale (VAS) pain scores between phases were taken and self-regulatory progress was tracked and summarized from a series of semi-structured interviews. Visual analysis of scores for each participant as single cases indicated decreases for the Dohsa-hou phase compared to baseline treatment-as-usual. As a result, participants reported using Dohsa-hou to reduce pain and experienced improvements in quality of life associated with greater self-regulatory capacity to attend to personal care and domestic activities. These preliminary findings suggest that Dohsa-hou body movement relaxation tasks were feasible as a coping skill in a hospital-integrated setting and at home and show promise for promoting quality of life vis-a-vis the management of severe and chronic bodily pain associated with end-stage renal disease and its treatment, particularly by improving aspects of pain-mediated self-regulatory fatigue.

A freshwater clam (Corbicula fluminea) extract improves cholesterol metabolism in rats fed on a high-cholesterol diet.

The effect of a freshwater clam (Corbicula fluminea) extract (FCE) on cholesterol metabolism in rats fed on a high-cholesterol diet was investigated. When rats were fed various amounts of FCE in addition to the high-cholesterol diet for 2 wk, the serum and hepatic cholesterol levels were gradually reduced in a dose-dependent manner, as compared with the control group. The excretion of neutral sterols and bile acids into the feces was increased by feeding FCE. Several phytosterols were detected in the feces of rats fed on the FCE-containing diet. In addition, substantial amounts of phytosterols were found in FCE. Cholesterol 7alpha-hydroxylase (CYP7A1) mRNA in the liver of the rats fed on the FCE-containing diets was higher than that of rats fed on the high-cholesterol diets without FCE. These results may suggest that enhanced cholesterol degradation and the excretion of neutral sterols and bile acids contributed to the hypocholesterolemic effect of FCE observed in the hypercholesterolemic rats fed on the high-cholesterol diet.
