Depressive Symptom Trajectories Among Sexually Abused Youth: Examining the Effects of Parental Perpetration and Age of Abuse Onset

Differential effects of lifetime stressors on major depressive disorder severity: a longitudinal community-based cohort study

BACKGROUND

Stressors across the lifespan are associated with the onset of major depressive disorder (MDD) and increased severity of depressive symptoms. However, it is unclear how lifetime stressors are related to specific MDD subtypes. The present study aims to examine the relationships between MDD subtypes and stressors experienced across the lifespan while considering potential confounders.

METHODS

Data analyzed were from the Zone d'Épidémiologie Psychiatrique du Sud-Ouest de Montréal (N = 1351). Lifetime stressors included childhood maltreatment, child-parent bonding, and stressful life events. Person-centered analyses were used to identify the clusters/profiles of the studied variables and multinomial logistic regression analyses were performed to examine the relationships between stressors and identified MDD subtypes. Intersectional analysis was applied to further examine how distal stressors interact with proximal stressors to impact the development of MDD subtypes.

RESULTS

There was a significant association between proximal stressors and melancholic depression, whereas severe atypical depression and moderate depression were only associated with some domains of stressful life events. Additionally, those with severe atypical depression and melancholic depression were more likely to be exposed to distal stressors such as childhood maltreatment. The combinations of distal and proximal stressors predicted a greater risk of all MDD subtypes except for moderate atypical depression.

CONCLUSIONS

MDD was characterized into four subtypes based on depressive symptoms and severity. Different stressor profiles were linked with various MDD subtypes. More specific interventions and clinical management are called to provide precision treatment for MDD patients with unique stressor profiles and MDD subtypes.

A prospective longitudinal study of multidomain resilience among youths with and without maltreatment histories

The majority of children with maltreatment histories do not go on to develop depression in their adolescent and adult years. These individuals are often identified as being "resilient", but this characterization may conceal difficulties that individuals with maltreatment histories might face in their interpersonal relationships, substance use, physical health, and/or socioeconomic outcomes in their later lives. This study examined how adolescents with maltreatment histories who exhibit low levels of depression function in other domains during their adult years. Longitudinal trajectories of depression (across ages 13-32) in individuals with (n = 3,809) and without (n = 8,249) maltreatment histories were modeled in the National Longitudinal Study of Adolescent to Adult Health. The same "Low," "increasing," and "declining" depression trajectories in both individuals with and without maltreatment histories were identified. Youths with maltreatment histories in the "low" depression trajectory reported lower romantic relationship satisfaction, more exposure to intimate partner and sexual violence, more alcohol abuse/dependency, and poorer general physical health compared to individuals without maltreatment histories in the same "low" depression trajectory in adulthood. Findings add further caution against labeling individuals as "resilient" based on a just single domain of functioning (low depression), as childhood maltreatment has harmful effects on a broad spectrum of functional domains.

Understanding posttraumatic stress trajectories in adolescent females: A strength-based machine learning approach examining risk and protective factors including online behaviors

Heterogeneity in the course of posttraumatic stress symptoms (PTSS) following a major life trauma such as childhood sexual abuse (CSA) can be attributed to numerous contextual factors, psychosocial risk, and family/peer support. The present study investigates a comprehensive set of baseline psychosocial risk and protective factors including online behaviors predicting empirically derived PTSS trajectories over time. Females aged 12-16 years (N = 440); 156 with substantiated CSA; 284 matched comparisons with various self-reported potentially traumatic events (PTEs) were assessed at baseline and then annually for 2 subsequent years. Latent growth mixture modeling (LGMM) was used to derive PTSS trajectories, and least absolute shrinkage and selection operator (LASSO) logistic regression was used to investigate psychosocial predictors including online behaviors of trajectories. LGMM revealed four PTSS trajectories: resilient (52.1%), emerging (9.3%), recovering (19.3%), and chronic (19.4%). Of the 23 predictors considered, nine were retained in the LASSO model discriminating resilient versus chronic trajectories including the absence of CSA and other PTEs, low incidences of exposure to sexual content online, minority ethnicity status, and the presence of additional psychosocial protective factors. Results provide insights into possible intervention targets to promote resilience in adolescence following PTEs.

One-year Cohort Follow-up on the Diagnosis and Posttraumatic Symptoms in Child Sexual Assault Victims in Korea

OBJECTIVE

The victims and their families of child sexual abuse (CSA) may confront persistent psychological sequela. We aimed to investigate the psychological symptoms, diagnosis, and family functions in children and adolescents with CSA.

METHODS

We assessed the symptom scales at 6-month intervals, and conducted diagnostic re-assessments at 1-year intervals. Trauma Symptom Checklist for Children (TSCC), Trauma Symptom Checklist for Young Children (TSCYC), Family Adaptability and Cohesion Evaluation Scales IV (FACES-IV), and Family Communication Scale (FCS) scores were reported by children or parents.

RESULTS

We found in parent-reported TSCYC, that posttraumatic stress symptoms domain scores significantly decreased with time progression. The scores decreased more in the evidence-based treatment group over time in anxiety and posttraumatic stress symptom domains of TSCC. In FACES-IV and FCS scores, indices of family function have been gradually increasing both after 6 months and after 1 year compared to the initial evaluation. Further, about 64% of the children diagnosed with psychiatric diseases, including posttraumatic stress disorder (PTSD) at the initial assessment maintained the same diagnosis at follow-up.

CONCLUSION

We observed changes in psychological symptoms and family functioning in sexually abused children with time progression during 1 year. It is postulated that PTSD may be a persistent major mental illness in the victims of CSA.

Long-Term Trajectories of Depressive Symptoms Among Children Affected by Parental HIV: A 12-Year Follow-Up Study

The present study explored the trajectories of depressive symptoms over 12 years spanning from childhood to emerging adulthood and the between-trajectory differences in psychosocial adjustment among Chinese children (N = 492, 52.8% boys, aged 6 to 18 years at baseline) affected by parental HIV. Rebounding (12.6%), resilient (64.8%), and improving  (22.6%) trajectories were identified. Individuals in the rebounding trajectory reported the highest levels of psychological distress and the lowest levels of subjective well-being, positive self-regard, and personal strengths in adulthood. Individuals in the resilient trajectory reported lower levels of psychological distress and negative affect than those in the improving trajectory. The findings support the development of programs by policymakers and practitioners to improve the psychosocial adjustment of children who have been affected by parental HIV while considering individual differences in the trajectories of depressive symptoms.

Child Sexual Abuse: The Need for a Perpetration Prevention Focus

In the evolution of efforts to reduce child sexual abuse (CSA) rates in the United States, there has been a gradual shift to add preventive measures to after-the-fact interventions (i.e., interventions and policies implemented after the abuse has already happened, such as services and treatment for victims and punishment, treatment, and management of offenders). Prevention of CSA perpetration, however, is often missing from these efforts, despite decades of experts calling for broader prevention solutions. The current paper describes the scope of the problem of CSA, highlights problems with an over-reliance on after-the-fact interventions, and describes promising perpetration-focused CSA prevention interventions. While most existing preventive efforts focus on teaching children to protect themselves from incurring sexual harm, perpetration prevention efforts may hold more promise by addressing the onset of harmful behavior. As such, perpetration prevention efforts can contribute to a more robust and comprehensive approach to CSA - an approach that focuses on prevention of harm from occurring in the first place, as well as responding once harm has occurred.
