Online Sexual Abuse and Symptomatology in Chilean Adolescents: The Role of Peer Support

Several authors are studying sexual abuse via the Internet and its consequences. However, the available studies have not sufficiently detected factors that could help reduce the symptoms that victims may experience. Given the importance of peers during adolescence, especially in the online world, the objective of this study was to evaluate the relationship between online sexual abuse, perceived peer support, and internalizing and externalizing symptomatology. Three hundred and eighty Chilean adolescents (M = 16.12 years, SD = .52, 49.7% girls, 50.3% boys) responded to a set of self-report instruments. The results showed a relationship between online sexual abuse and depressive symptomatology, as well as self-injurious and antisocial behaviors. In turn, peer support was inversely associated with internalizing symptomatology. Results of the study highlight the relevance of peers as factors in intervention programs for adolescents dealing with online sexual abuse.

Chronic Illness and Internalizing Symptomatology in a Transdiagnostic Clinical Sample of Youth

Objective In research with community samples, children with chronic physical illnesses have shown elevated anxiety and depressive symptoms, compared to healthy peers. Less is known about whether physical illnesses are associated with elevated internalizing symptoms even among children referred for mental health treatment—a pattern that would indicate distinctive treatment needs among physically ill children receiving mental health care. We investigated the relationship between chronic physical illness and internalizing symptomatology among children enrolling in outpatient mental health treatment. Method A total of 262 treatment-seeking children ages 7–15 and their caregivers completed a demographic questionnaire, Child Behavior Checklist, and Youth Self-Report during a pre-treatment assessment. Physical illnesses were identified through caregiver report. Results There was no overall association between the presence/absence of chronic physical illness and parent- or child-reported symptoms. However, number of chronic physical illnesses was related to parent- and child-reported affective symptoms. Children with two or more chronic physical illnesses had more severe depressive symptoms than those with fewer physical illnesses. Conclusion Having multiple chronic illnesses may elevate children’s risk of depression symptomatology, even in comparison to other children seeking mental health care. This suggests a need to identify factors that may exacerbate depression symptoms in physically ill children who are initiating therapy and to determine whether different or more intensive services may be helpful for this group. The findings suggest the potential utility of screening for depression in youth with chronic physical illnesses, as well as addressing mental and physical health concerns during treatment.

Emerging Adults’ Psychopathology in Seven Countries: The Impact of Identity-Related Risk Factors

The impact of identity-related risk factors on psychopathology was analyzed in 2,113 emerging adults ( M = 22.0 years; 66% female) from France, Germany, Turkey, Greece, Peru, Pakistan, and Poland. Identity stress, coping with identity stress, maternal parenting (support, psychological control, and anxious rearing), and psychopathology (internalizing, externalizing, and total symptomatology) were assessed. After partialing out the influence of stress, coping, and perceived maternal behavior, country did no longer exert a significant effect on symptom scores. The effect for gender remained, as did an interaction between country and gender. Rather unexpected, on average, males reported higher internalizing symptomatology scores than females. Potential causes for the higher scores of males are therefore discussed. Partialing out covariates resulted in a clearer picture of country-specific and gender-dependent effects on psychopathology, which is helpful in designing interventions.

Heightened connectivity between the ventral striatum and medial prefrontal cortex as a biomarker for stress-related psychopathology: understanding interactive effects of early and more recent stress

BackgroundThe experience of childhood maltreatment is a significant risk factor for the development of depression. This risk is particularly heightened after exposure to additional, more contemporaneous stress. While behavioral evidence exists for this relation, little is known about biological correlates of these stress interactions. Identifying such correlates may provide biomarkers of risk for later depression.MethodsHere, we leverage behavioral, experiential, and neuroimaging data from the Duke Neurogenetics Study to identify potential biomarkers of stress exposure. Based on the past research, we were specifically interested in reward-related connectivity and the interaction of early and more recent stress. We examined psychophysiological interactions between the ventral striatum and other brain regions in relation to these stress variables, as well as measures of internalizing symptomatology (n = 926, participant age range = 18–22 years of age).ResultsWe found relatively increased reward-related functional connectivity between the left ventral striatum and the medial prefrontal cortex in individuals exposed to greater levels of childhood maltreatment who also experienced greater levels of recent life stress (β = 0.199, p < 0.005). This pattern of functional connectivity was further associated with elevated symptoms of depression (β = 0.089, p = 0.006). Furthermore, using a moderated mediation framework, we demonstrate that this functional connectivity provides a biological link between cumulative stress exposure and internalizing symptomatology.ConclusionsThese findings suggest a novel biomarker linking cumulative stress exposure with the later experience of depressive symptoms. Our results are discussed in the context of past research examining stress exposure in relation to depression.

Gendered pathways to young adult symptomatology

The transition to adulthood is a critical juncture in the course of psychopathology. This study examined the ways in which earlier capacity to deal with relationship stress during adolescence contributed to an adaptive outcome in emerging adulthood. In a prospective study of 145 individuals, relationship stress, individual coping capacities, and perceived support from fathers, mothers, and peers were analyzed, when the participants were 13 and 17 years old. The effects of these earlier capacities to deal with relationship stress on health outcomes were examined in young adulthood (age 23). Gendered pathways to young adults’ symptomatology emerged. Females experiencing earlier relationship stress, but also support by mothers, fathers, and friends, showed less symptomatology at age 23. In addition, females’ withdrawal coping mediated the impact of stressful encounters on later internalizing symptomatology. In contrast, earlier coping with relationship stress was not found to be predictive for males. Earlier support from parents or friends was associated with later externalizing symptomatology in young men. Reasons for the gender-specific pathways to symptomatology are discussed.
