Post-traumatic stress symptom development as a function of changing witnessing in-home violence and changing peer relationship quality: Evaluating protective effects of peer relationship quality

Quality of the Parent-Child Relationship as a Moderator of Witnessing Violence and Youth Trauma Symptoms

Traumatic event exposure affects two in every three adolescents in the United States and there is the potential for numerous deleterious effects including higher levels of youth depression, anxiety, posttraumatic stress symptoms, and emotional and behavioral problems. Witnessing violence is one of the more common experiences associated with trauma exposure. Despite the ample research on mental health outcomes associated with witnessing violence, less is known about the extent to which parent-child relationships play a role in youth mental health outcomes when youth are exposed to violence. With a clinically relevant, diverse sample of 806 youth ages 12 years old who experienced maltreatment or were at risk of being maltreated, we tested hypotheses that the parent-child relationship quality would moderate the associations between witnessing violence and youth mental health outcomes. Results supported hypotheses for youths' symptoms of anxiety, depression, dissociation, and posttraumatic stress. The study contributes to the trauma literature by determining that the quality of the parent-child relationship moderated the effects of witnessing violence on trauma outcomes.

Exposure to Intimate-Partner Violence and Resilience Trajectories of Adolescents: A Two-Wave Longitudinal Latent Transition Analysis

Despite the serious emotional and social consequences of adolescents' exposure to intimate-partner violence (IPV) and the high prevalence of this exposure, few analyses have focused on person-centered models or considered psychological IPV. Studies that address exposure to violence tend to focus on physical IPV. Therefore, in this study, we examine (across two waves) the trajectories of resilience among adolescents who have witnessed psychological IPV by conducting a latent transition analysis and predicting class membership through socio-demographic and individual-level protective factors. Using a sample of 879 (T1, fall 2020) and 770 (T2, spring 2022) adolescent Swiss students with mean ages of 11.74 (SD = 0.64) and 13.77 (SD = 0.53), we identified four distinct time-invariant resilience classes: comorbid-frustrated, internalizing-frustrated, comorbid-satisfied, and resilient. The classes characterized by some level of psychopathological symptoms and basic psychological-needs frustration were the most stable over time. Furthermore, we found the four typical resilience trajectories: recovery, chronic, delayed, and improving. Gender, socioeconomic background, and protective factors showed a significant prediction of class membership in wave 1, highlighting the importance of increasing sensitivity to psychological-IPV exposure on the one hand, and reinforcing the relevance of prevention in schools regarding the promotion of protective factors on the other.

Trajectories of peer relationship problems and emotional symptoms in children 5 years after a nuclear disaster: Fukushima Health Management Survey

The Fukushima Daiichi Nuclear Power Station (NPS) accident, which occurred in March 2011, is having long-term effects on children. About 3 years after the accident, we identified three patterns of peer relationship problems and four patterns of emotional symptoms using group-based trajectory modeling. As a result, we reported that different factors might be related to very severe trajectories of peer relationship problems and emotional symptoms. In this study, we used five waves of data from fiscal year (FY) 2011 to FY2015 from the Mental Health and Lifestyle Survey, a detailed survey of the Fukushima Health Management Survey started in FY2011. We analyzed 7013 residents within the government-designated evacuation zone (aged 6-12 years old as of 11 March 2011) with responses to all items of psychological distress in at least one wave from FY2011 and FY2015. We planned this study to describe the trajectories of peer relationship problems and emotional symptoms in children and to examine potential risks and protective factors over the 5 years following the NPS accident. We identified four patterns of peer relationship problems and five patterns of emotional symptoms using latent class growth analysis. For peer relationship problems, male sex, experiencing the NPS explosion and lack of exercise habits were associated with the severe trajectory group. For emotional symptoms, experiencing the NPS explosion, experiencing the tsunami disaster and lack of exercise habits were associated with the severe trajectory group. Exercise habits are very important for the mental health of evacuees after a nuclear disaster.

The contribution of interpersonal violence victimization types to psychological distress among youth

BACKGROUND

Associations between different types of victimization and symptomology among youth remain unclear due to methodological limitations preventing the identification of the independent contribution of each type of violence.

OBJECTIVE

The purpose was to examine associations between different types of victimization and the odds of experiencing clinically significant levels of anxiety, depression, and anger/aggression. We also examined the unique contribution of each type of victimization to these outcomes.

PARTICIPANTS

Participants were a nationally representative sample of youth ages 10-17 (n = 1019) who were residing in the United States when data were collected in 2002-2003.

METHODS

Youth reported on their experiences of different forms of victimization (e.g., physical abuse, emotional abuse, neglect, sibling abuse, bullying, sexual assault, and witnessing violence) within the past year. Logistic regression and relative weights analyses were used to examine associations between victimization and symptoms of depression, anxiety, and anger/aggression.

RESULTS

The prevalence of reported victimization ranged from 1.3 % for neglect to 41.3% for sibling abuse. Physical and emotional child abuse, sibling abuse, bullying, and emotional bullying were associated with increased odds of clinically significant anxiety, depression, and anger/aggression. Witnessing parent intimate partner violence was associated with increased odds of clinically significant anger/aggression. Witnessing parental assault of a sibling was associated with increased odds of clinically significant anxiety and anger/aggression. Emotional bullying predicted the largest percentage of variance in anxiety and depression, followed by emotional abuse and sibling aggression.

CONCLUSIONS

These findings underscore the need for further assessment and treatment for sibling abuse and emotional bullying.
