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.

Does Trauma Shape Identity? Exploring the Links Between Lifetime Trauma Exposure and Identity Status in Emerging Adulthood.

In emerging adulthood, coherent identity plays a protective role against the development of the disturbed psychosocial functioning and is seen as one of the defining characteristics of positive youth development. The factors that shape the identity are still understudied and little quantitative research has addressed, how trauma exposure is linked to emerging adults' identity. Therefore, the current study aimed to investigate how exposure to traumatic experiences over the lifetime is associated with current identity status among emerging adults in an academic environment and to explore links between different types of traumatic experiences as well as the severity of exposure to trauma and identity statuses. The study sample consisted of 1,614 first-year undergraduate students from Lithuania with the age range of 18-29 years (M = 19.09, SD = 1.05, 68.28% female). The three distinct identity profiles were identified using the Latent Class Analysis, representing diffused, undifferentiated, and coherent identity statuses. The results provided no clear evidence of links between traumatic experiences and identity status for overall exposure and most types of traumatic events. However, our study concerns the potential importance of severe traumatic experiences, such as sexual trauma, on identity.

Prejudice and Health Anxiety about Radiation Exposure from Second-Generation Atomic Bomb Survivors: Results from a Qualitative Interview Study.

The effect of atomic bomb radiation exposure on the survivors and their children has been a worrisome problem since soon after the 1945 Hiroshima and Nagasaki bombings. Researchers have examined physical and genetic effects; however, no research has focused on second-generation survivors' (SGS) psychological effects. Consequently, this study shed light on the SGS' experience of discrimination and prejudice and their anxiety concerning the genetic effects of radiation exposure. This study utilized semi-structured interviews with 14 SGS (10 women, mean age = 56 ± 6.25 years, range = 46-68 years). Data were analyzed using a modified version of the grounded theory approach. Three categories were extracted: low awareness as an SGS, no health anxiety regarding the effect of radiation, and health anxiety regarding the effect of radiation. The results did not reveal that SGS who grew up in the bombed areas experienced discrimination or prejudice. They had little health anxiety from childhood to adolescence. In this study, some of the SGS developed health anxiety about their third-generation children, but only among female participants. Perhaps the transgenerational transmission of anxiety concerning the genetic effects of radiation exposure causes stress, particularly among women with children. However, a change was seen in adulthood health anxiety regarding the effects of radiation, suggesting the possibility that changes in the psychological experiences of SGS can be observed throughout their lifetimes and that their own health status, and that of their children, the third-generation survivors, affects their health anxiety regarding radiation.
