Life stress versus traumatic stress: The impact of life events on psychological functioning in children with and without serious illness

Modelling the Relationship Between Resilience to Depression and Recent Stressful Life Events in University Students

Resilience, or successful coping with the experience of stressful life events (SLEs), protects against depression, but its operational mechanisms are unclear. Views diverge whether resilience intervenes as a trait or as a process of dynamic interactions of protective factors, such as self-esteem, social support and family cohesion. We evaluated five theoretically-based models of how resilience, defined as either a trait or a process, interacts with recent SLEs, to explain depressive symptomatology in 2434 university students. The moderating effect of problematic, age-inappropriate parenting (i.e., helicopter parenting) was also assessed. SLEs moderated both the effects of trait and process resilience on depression, but models conceptualising resilience as a dynamic process of interacting components showed better explanatory power than models conceptualising resilience solely as a trait. Trait resilience was protective through self-esteem at all levels of SLEs exposure (low, mild, moderate or high), and significantly, but less so through hope or social support. Experiencing helicopter parenting weakened the protective influence of process resilience, through decreasing family cohesion in the presence of SLEs. The overall assessment of the five models supports a process conceptualisation of resilience to depression in the face of adversity. However, the results also suggest that not all protective factors are equally important, with self-esteem appearing a significant and strong mediator of resilience to depression in all models including it as a variable. Building process resilience is proposed as a key intervention target for depressive symptoms. Clinical assessments and interventions following SLEs should routinely consider both trait resilience and self-esteem, as the interaction of these two factors protects against depression even at the highest levels of adversity exposure. Depression prevention approaches should address the individual's experience of overparenting, given the deleterious influence of helicopter parenting on resilience.

Associations of recent stressful life events with anxiety symptoms among Chinese adolescents with a consideration of family functioning

Background: The association between stressful life events (SLEs) and adolescent anxiety symptoms has been extensively studied, but the specific impacts of different SLEs domains remain inconclusive. Moreover, limited research has examined the role of family functioning in these associations.Objective: This study aimed to investigate the associations between various recent SLEs and adolescent anxiety symptoms and explore the role of family functioning.Methods: Data were obtained from the second phase of the Longitudinal Study of Adolescents' Mental and Behavioral Well-being Research in Guangzhou, China. A total of 10,985 students (51.9% boys; mean [SD] age, 15.3 [1.5] years) from forty middle schools participated in the study in 2022 and completed a self-report questionnaire assessing anxiety symptoms, SLEs, and family functioning using the Generalized Anxiety Disorder-7 (GAD-7), Adolescent Self-rating Life Events Checklist (ASLEC; including five subscales: interpersonal stress, academic stress, punishment-related stress, loss-related stress, and adaptation-related stress), and the adapted Chinese version of the Family Assessment Device (FAD), respectively. Linear mixed-effects models were performed and the moderation role of family functioning was also examined.Results: The fully adjusted model revealed that a 1-SD increase in the overall ASLEC score was associated with higher levels of anxiety symptoms (β = 2.23, 95%CI: 2.15-2.32). Among various SLEs domains, the academic domain shows the most significant association (β = 2.25, 95%CI: 2.17-2.33). Family functioning exerted an independent protective influence on anxiety symptoms, with each 1-SD increase in FAD scores negatively associated with anxiety symptoms (β = -2.11, 95%CI: - 2.29 to - 1.93) in the adjusted model. Moreover, family functioning significantly buffered the impacts of overall SLEs and each domain, except for adaptation-related SLEs, on anxiety symptoms.Conclusion: Higher recent SLEs levels were associated with increased anxiety symptoms among adolescents, with academic SLEs showing the greatest association. Positive family functioning had both direct and buffering influences on anxiety symptoms.

Adolescent patient with post traumatic stress disorder due atypical stressor: Case report

INTRODUCTION

Post-traumatic stress disorder (PTSD) is characterised by intrusive, anxious, and avoidant symptoms that are triggered after a stressful experience and affect the mood. The definition of a stressor that generates PTSD has been debated in recent years, as a clinical picture compatible with the disorder can occur after exposure to stressors that do not meet the criteria A1 of the DSM V; these stressors have been defined in the literature as "of low magnitude, uncommon, unusual or atypical".

CLINICAL CASE

We present the clinical case of a paediatric patient who developed PTSD after being exposed to an atypical stressor.

CONCLUSIONS

The literature shows these stressors to be more frequently documented in the paediatric population. We therefore suggest that cases should be analysed as a complex interweaving of variables, where one of the most important is each patient's interpretation of the event according to their life history and social context, and not because of an inherent characteristic of the stressor itself.

The association between stressful experiences and OCD symptoms in young adults at transdiagnostic risk

BACKGROUND

It is unclear whether there is a specific association between stressful experiences and obsessive-compulsive symptoms or whether this relationship is due to stressful experiences increasing risk for psychopathology generally.

AIMS

The current study examined the association between stressful experiences and obsessive-compulsive symptom dimensions, while adjusting for coexisting psychiatric symptoms and psychological distress in a young adult transdiagnostic at-risk sample.

METHODS

Forty-three participants completed self-report measures assessing obsessive-compulsive symptoms, stressful experiences, and a range of other psychiatric symptoms. Regression models examined the relationship between stressful experiences and different obsessive-compulsive symptoms dimensions (i.e., symmetry, fear of harm, contamination, and unacceptable thoughts), adjusting for the influence of coexisting psychiatric symptoms and psychological distress.

RESULTS

The results showed that there was an association between stressful experiences and obsessive-compulsive symptoms dimension of symmetry. Symptoms of borderline personality disorder were positively associated with the obsessive-compulsive symptom dimensions of symmetry and fear of harm symptoms. Symptoms of psychosis were found to be negatively associated with the obsessive-compulsive symptoms dimension of fear of harm.

CONCLUSIONS

These findings have implications for understanding the psychological mechanisms that underlie symmetry symptoms and highlight the need to study OCS dimensions separately to inform more precise, mechanism-targeted interventions.

Association Among Negative Life Events, Sense of Security, and Depressive Symptoms in Chinese Adolescents After the 2013 Ya'an Earthquake

OBJECTIVE

About a fourth of Chinese adolescents developed clinically significant depressive symptoms following a disaster. However, little is known about whether and how post-trauma negative life events and a sense of security are associated with depressive symptoms in this population. This study examined the psychological experiences of Chinese young people who had experienced the 2013 Ya'an earthquake in Sichuan, China.

METHODS

This cross-sectional study was conducted in 2019. A total of 693 Chinese middle school students completed a questionnaire that measured their level of depressive symptoms, trauma exposure, stressful life events, and sense of security.

RESULTS

Results of hierarchical multiple-regression analyses showed that the level of life stress from stressful life events was positively associated with the level of depressive symptoms (β = 0.416, P < 0.001) and the level of the sense of security was negatively associated with the level of depressive symptoms (β = -0.352, P < 0.001) when analysis controlled for age, gender, and trauma exposure.

CONCLUSIONS

These findings highlight the importance of considering the influence of life stressors and the sense of security in devising measures and strategies for the prevention of the manifestation of depression among young people, particularly those who were exposed to disasters.

Definitions, theories, and measurement of stress in children

PROBLEM

Stress in children remains a complex concept to examine due to the inherent subjectivity and lack of specific manifestations, as well as the multiple ways stress can be defined and measured in children. Because stress is multifactorial,is experienced daily by children, and undergirds adolescent health and early mental illness, it is crucial to have a clear understanding of stress and the effects of stress in children from infancy through age twelve years.

ELIGIBILITY CRITERIA

To be included in this review, literature must pertain to and highlight theories, definitions/classifications, and measurements of stress in children from infancy to 12 years of age.

SAMPLE

The most pertinent articles identified through database searches (PubMed, Scopus, PsycINFO, CINAHL, Google Scholar), gray literature sources (e.g., child health websites), and reference lists of identified articles were included in this narrative overview.

RESULTS

The results of this review are organized by themes and include: classifications and definitions of stress, stress-related theories, and tools to measure stress in children.

CONCLUSIONS

Research addressing stressors and stress in children is limited, and there is wide variation in how researchers define and classify stress in children. Existing measures of stress in children younger than 12 address physiological, psychological, and observational components, but may be inconsistent and threaten validity of otherwise well-designed and well-executed studies.

IMPLICATIONS

Improving the understanding and accurate measurement of stress in children enables researchers and clinicians to curtail undesirable health outcomes.

The mediating role of post-traumatic stress disorder symptoms in the relationship between childhood adversities and depressive symptoms in two samples

BACKGROUND

Childhood adversities have been increasingly recognized as a significant risk factor for depression. However, the underlying mediating mechanism between childhood adversities and depression requires further investigation. The literature shows that childhood adversities are also closely associated with post-traumatic stress disorder (PTSD) symptoms and that PTSD symptoms can predict depressive symptoms. It remains unexplored whether PTSD symptoms can act as a mediator between childhood adversities and depression.

OBJECTIVES

The primary goal of this study was to examine whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms.

PARTICIPANTS AND SETTING

We examined in a convenience sample of Hong Kong adults aged 18 or above (N = 418) whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms. We then examined and compared the results with those in another convenience sample of Chinese-speaking young adults (mainly from Taiwan and Hong Kong) aged between 18 and 24 (N = 205). Participants in both samples completed online surveys that included measures of childhood adversities, PTSD symptoms and depressive symptoms.

RESULTS

Childhood adversities were significantly associated with depressive symptoms; and this relationship was mediated by PTSD symptoms in both samples.

CONCLUSION

This study is one of very few studies demonstrating that PTSD symptoms mediate the relationship between childhood adversities and depressive symptoms. Our findings suggest that addressing unresolved PTSD symptoms for adults with childhood adversities may help in preventing or treating depressive symptoms. Therefore, PTSD symptoms should be taken into account in the prevention and management of depression.

Posttraumatic Stress Disorder, Suicidal Behavior, Substance Use, and Sexual Victimization Among Adolescent Girls Aged 10-19 Years Living Under Ethnic-Based Civil War in Ethiopia

BACKGROUND

Posttraumatic stress disorder (PTSD) is a chronic, impairing mental disorder that develops after exposure to a traumatic event. Despite many factors putting adolescent girls at risk of PTSD, little is known about the prevalence and how adolescent girls cope with the PTSD burden. So, this study aimed to investigate the prevalence of PTSD and associated factors among adolescent girls in three selected towns in Southwest Ethiopia.

METHODS

A community-based cross-sectional study was conducted among 397 adolescent girls from May 27 to July 27, 2021. The participants were selected by a systematic random sampling method. PTSD and substance use disorder were assessed by DSM V criteria for mental disorders. The data was entered into Epi Data Manager Version 4.0.2 before being exported to SPSS Version 25 for analysis. A logistic regression model was used, and variables with a p-value less than 0.05 in the final fitting model were stated as independent predictors of PTSD.

RESULTS

The prevalence of PTSD among the adolescent girls was 22%, and about three in four (72.7%) of the adolescent girls developed PTSD after exposure to sexual violence. Furthermore, PTSD was associated with Khat use disorder (AOR, 95% CI: 2.79 (1.47-5.30), alcohol use disorder (AOR, 95% CI: 5.27 (2.21-12.60), and suicidal behavior (AOR, 95% CI: 2.12 (1.20-3.74)).

CONCLUSION

The prevalence of PTSD was high among adolescent girls, and suicidal ideation or attempt, khat use disorder, and alcohol use disorder were risk factors for PTSD. Therefore, early screening for PTSD and comorbid risk factors among this particular age group and managing accordingly is warranted.

Prevalence and factors associated with PTSD among female urban slum dwellers in Ibadan, Nigeria: a cross-sectional study

BACKGROUND

Little is known about the prevalence of and factors associated with PTSD among adult females in Nigeria, particularly those who live in slums. PTSD is a mental health condition that develops among some individuals who experience or witness a traumatic event. Several other factors could place individuals at heightened risk of PTSD including stress and comorbid mental disorders. Therefore, this study aimed to examine the prevalence and factors associated with PTSD among female urban slum dwellers in Ibadan, Nigeria.

METHODS

We conducted a cross sectional survey using multistage sampling of 550 women aged 18 and above from selected slums. Interviewer administered questionnaires were used to elicit information on experience of childhood trauma, recent stressors, intimate partner violence, other mental disorders, sociodemographic characteristics and PTSD. PTSD was measured using the Harvard Trauma Questionnaire (HTQ) which is based on DSM IV. A multivariable linear regression model was built to test associations between PTSD and independent variables.

RESULTS

The prevalence for PTSD was found to be 4.18% and the mean PTSD score was 5.80 ± 7.11. Sexual abuse in childhood, past year intimate partner violence and anxiety were significantly associated with higher PTSD scores. PTSD was not significantly associated with a history of recent stressors. Education, employment and marital status were not associated with PTSD however, age and wealth index showed marginal association with PTSD.

CONCLUSION

The prevalence of PTSD among women living in Ibadan slums was relatively low. Both child sexual abuse and intimate partner violence can be prevented. We also recommend longitudinal studies to better understand risk and protective factors.

Deliberate Context-Driven Conceptualization in Psychological Assessment

Clinical formulation and case conceptualization in clinical psychological assessment typically organize a client's presenting problems within a psychological framework and narrative that explains the cluster of symptoms, etiological and maintenance factors, and explaining both how and why a client is struggling or suffering. However, many of the most commonly used models of case conceptualization, as well as the preponderance of tests and measures used in psychological assessment, minimize or ignore the impacts of contextual factors, including dominant culture's expectations for normative behavior and the client's history of trauma and adverse and negative events. This paper presents a rationale and model for encouraging psychologists conducting clinical psychological assessment to be deliberate in first considering contextual factors in case conceptualization before relying entirely on primarily intrapsychic models. While contextual conceptualizations will not always replace (or join) intrapsychic models of case formulation, being deliberate and explicit about at least considering them is an important way to mitigate some of psychologists' biases and has the potential to situate a narrative of client difficulties in a way that takes at least some of the burden off the client.

Sex-Dependent Changes in miRNA Expression in the Bed Nucleus of the Stria Terminalis Following Stress

Anxiety disorders disproportionately affect women compared to men, which may arise from sex differences in stress responses. MiRNAs are small non-coding RNAs known to regulate gene expression through actions on mRNAs. MiRNAs are regulated, in part, by factors such as stress and gonadal sex, and they have been implicated in the pathophysiology of multiple psychiatric disorders. Here, we assessed putative sex differences in miRNA expression in the bed nucleus of the stria terminalis (BNST) – a sexually dimorphic brain region implicated in anxiety – of adult male and female rats that had been exposed to social isolation (SI) stress throughout adolescence. To assess the translational utility of our results, we assessed if childhood trauma in humans resulted in changes in blood miRNA expression that are similar to those observed in rats. Male and female Sprague-Dawley rats underwent SI during adolescence or remained group housed (GH) and were tested for anxiety-like behavior in the elevated plus maze as adults. Small RNA sequencing was performed on tissue extracted from the BNST. Furthermore, we re-analyzed an already available small RNA sequencing data set from the Grady Trauma Project (GTP) from men and women to identify circulating miRNAs that are associated with childhood trauma exposure. Our results indicated that there were greater anxiogenic-like effects and changes in BNST miRNA expression in SI versus GH females compared to SI versus GH males. In addition, we found nine miRNAs that were regulated in both the BNST from SI compared to GH rats and in blood samples from humans exposed to childhood trauma. These studies emphasize the utility of rodent models in studying neurobiological mechanisms underlying psychiatric disorders and suggest that rodent models could be used to identify novel sex-specific pharmacotherapies for anxiety disorders.

Pediatric cancer, posttraumatic stress and fear-related neural circuitry

This review examines the neurobiological effects of pediatric cancer-related posttraumatic stress symptoms (PTSS). We first consider studies on prevalence and predictors of childhood cancer-related PTSS and compare these studies to those in typically developing (i.e., noncancer) populations. Then, we briefly introduce the brain regions implicated in PTSS and review neuroimaging studies examining the neural correlates of PTSS in noncancer populations. Next, we present a framework and recommendations for future research. In particular, concurrent evaluation of PTSS and neuroimaging, as well as sociodemographic, medical, family factors, and other life events, are needed to uncover mechanisms leading to cancer-related PTSS. We review findings from neuroimaging studies on childhood cancer and one recent study on cancer-related PTSS as a starting point in this line of research.

Systematic Review: Bullying Involvement of Children With and Without Chronic Physical Illness and/or Physical/Sensory Disability-a Meta-Analytic Comparison With Healthy/Nondisabled Peers

Objective

To compare levels of victimization and perpetration associated with bullying among children and adolescents with and without chronic physical illnesses and/or physical or sensory disabilities.

Methods

In total, 107 studies were identified using a systematic search in electronic databases and cross-referencing. A random-effects meta-analysis was computed.

Results

Children and adolescents with chronic physical illness or disability were more likely to be victims of bullying in general (odds ratio [OR] = 1.65), particularly physical bullying (OR = 1.47), relational bullying (OR = 1.47), verbal bullying (OR = 1.67), cyberbullying (OR = 1.39), and illness-specific teasing (OR = 5.29). They were also more likely to be bullies in general (OR = 1.28), as well physical (OR = 1.38) and relational bullies (OR = 1.13). The effect sizes varied across different illnesses and disabilities and, in part, by visibility of the disease, school type, and year of assessment.

Conclusions

Although most between-group differences tend to be small, some form of intervention is needed to reduce bullying among children and adolescents with chronic physical illnesses and/or physical or sensory disabilities, and illness-specific weight- and appearance-related teasing in particular.

Cancer as a stressful life event: Perceptions of children with cancer and their peers

BACKGROUND

The medical traumatic stress model is commonly applied to childhood cancer, assuming that the diagnosis of cancer is a traumatic event. However, to the authors' knowledge, little is known regarding what specifically children perceive as stressful about cancer or how it compares with other stressful events more often experienced by children.

METHODS

Children with cancer (254 children) and demographically similar peers without a history of serious illness (202 children) identified their most stressful life event as part of a diagnostic interview assessing for symptoms of posttraumatic stress disorder (PTSD). The events identified as most stressful were categorized thematically, with categories established separately for cancer-related and non-cancer-related events. Events also were examined to assess whether they met Diagnostic and Statistical Manual of Mental Disorders (DSM) A criteria for PTSD.

RESULTS

In the group of children with cancer, 54% described a cancer-related event as the most stressful event they had experienced. Six distinct categories of cancer-related events and 10 categories of non-cancer-related events were identified. The same noncancer events were identified by children in both groups, and occurred at similar frequencies. The percentage of cancer-related events that met DSM A criteria for PTSD differed dramatically depending on which version of the DSM was applied.

CONCLUSIONS

Children do not necessarily view their cancer experience as their most stressful life event. The findings of the current study suggest that the diagnosis of cancer might be better viewed as a manageable stressor rather than a major trauma, and are consistent with the change in the fifth edition of the DSM to eliminate the diagnosis of a life-threatening illness as a qualifying trauma for PTSD.

Posttraumatic stress disorder symptoms in youth with vs without chronic pain

Chronic pain and posttraumatic stress disorder (PTSD) symptoms have been found to co-occur in adults; however, research has not examined this co-occurrence in adolescence, when pediatric chronic pain often first emerges. The aims of this study were to compare the frequency and intensity of PTSD symptoms and stressful life events in cohorts of youth with (n = 95) and without (n = 100) chronic pain and their parents and to determine the association between PTSD symptoms, health-related quality of life, and pain symptoms within the chronic pain sample. All participants completed questionnaire measures through an online survey. Findings revealed that youth with chronic pain and their parents had significantly higher levels of PTSD symptoms as compared with pain-free peers. More youth with chronic pain (32%) and their parents (20%) reported clinically significant elevations in PTSD symptoms than youth without chronic pain (8%) and their parents (1%). Youth with chronic pain also reported a greater number of stressful life events than those without chronic pain, and this was associated with higher PTSD symptoms. Among the chronic pain cohort, higher levels of PTSD symptoms were predictive of worse health-related quality of life and were associated with higher pain intensity, unpleasantness, and interference. Results suggest that elevated PTSD symptoms are common and linked to reduced functioning among youth with chronic pain. Future research is needed to examine PTSD at the diagnostic level and the underlying mechanisms that may explain why this co-occurrence exists.

Healthy Learning Mind - a school-based mindfulness and relaxation program: a study protocol for a cluster randomized controlled trial

BACKGROUND

Mindfulness has shown positive effects on mental health, mental capacity and well-being among adult population. Among children and adolescents, previous research on the effectiveness of mindfulness interventions on health and well-being has shown promising results, but studies with methodologically sound designs have been called for. Few intervention studies in this population have compared the effectiveness of mindfulness programs to alternative intervention programs with adequate sample sizes.

METHODS/DESIGN

Our primary aim is to explore the effectiveness of a school-based mindfulness intervention program compared to a standard relaxation program among a non-clinical children and adolescent sample, and a non-treatment control group in school context. In this study, we systematically examine the effects of mindfulness intervention on mental well-being (primary outcomes being resilience; existence/absence of depressive symptoms; experienced psychological strengths and difficulties), cognitive functions, psychophysiological responses, academic achievements, and motivational determinants of practicing mindfulness. The design is a cluster randomized controlled trial with three arms (mindfulness intervention group, active control group, non-treatment group) and the sample includes 59 Finnish schools and approx. 3 000 students aged 12-15 years. Intervention consists of nine mindfulness based lessons, 45 mins per week, for 9 weeks, the dose being identical in active control group receiving standard relaxation program called Relax. The programs are delivered by 14 educated facilitators. Students, their teachers and parents will fill-in the research questionnaires before and after the intervention, and they will all be followed up 6 months after baseline. Additionally, students will be followed 12 months after baseline. For longer follow-up, consent to linking the data to the main health registers has been asked from students and their parents.

DISCUSSION

The present study examines systematically the effectiveness of a school-based mindfulness program compared to a standard relaxation program, and a non-treatment control group. A strength of the current study lies in its methodologically rigorous, randomized controlled study design, which allows novel evidence on the effectiveness of mindfulness over and above a standard relaxation program.

Profiles of Resilience and Growth in Youth With Cancer and Healthy Comparisons

OBJECTIVE

Inconsistent links between posttraumatic stress symptoms (PTS) and posttraumatic growth (PTG) in youth following a stressful life event have been observed in previous literature. Latent profile analysis (LPA) provides a novel approach to examine the heterogeneity of relations between these constructs.

METHOD

Participants were 435 youth (cancer group=253; healthy comparisons = 182) and one parent. Children completed measures of PTS, PTG, and a life-events checklist. Parents reported on their own PTS and PTG. LPA was conducted to identify distinct adjustment classes.

RESULTS

LPA revealed three profiles. The majority of youth (83%) fell into two resilient groups differing by levels of PTG. Several factors predicted youth's profile membership.

CONCLUSIONS

PTS and PTG appear to be relatively independent constructs, and their relation is dependent on contextual factors. The majority of youth appear to be resilient, and even those who experience significant distress were able to find benefit.
