Attenuation of cortisol across development for victims of sexual abuse / Penelope K. TRICKETT in Development and Psychopathology, 22-1 (January 2010)  

Public ISBD [article]  inDevelopment and Psychopathology > 22-1 (January 2010) . - p.165-175 Titre : Attenuation of cortisol across development for victims of sexual abuse Type de document : Texte imprimé et/ou numérique Auteurs : Penelope K. TRICKETT, Auteur ; Frank W. PUTNAM, Auteur ; Jennie G. NOLL, Auteur ; Elizabeth J. SUSMAN, Auteur ; Chad E. SHENK, Auteur Année de publication : 2010 Article en page(s) : p.165-175 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Inconsistencies exist in literature examining hypothalamic–pituitary–adrenal (HPA) axis activity in children and adults who have experienced childhood abuse. Hence, the extent and manner to which childhood abuse may disrupt HPA axis development is largely unknown. To address these inconsistencies, the developmental course of nonstress cortisol in a long-term longitudinal study was assessed at six time points from childhood through adolescence and into young adulthood to determine whether childhood abuse results in disrupted cortisol activity. Nonstress, morning cortisol was measured in 84 females with confirmed familial sexual abuse and 89 nonabused, comparison females. Although dynamically controlling for co-occurring depression and anxiety, hierarchical linear modeling (HLM) showed that relative to comparison females, the linear trend for abused females was significantly less steep when cortisol was examined across development from age 6 to age 30, t (1, 180) = −2.55, p < .01, indicating attenuation in cortisol activity starting in adolescence with significantly lower levels of cortisol by early adulthood, F (1, 162) = 4.78, p < .01. As a more direct test of the attenuation hypothesis, supplemental HLM analyses of data arrayed by time since the disclosure of abuse indicated that cortisol activity was initially significantly higher, t (1, 425) = 2.18, p < .05, and slopes were significantly less steep t (1, 205) = −2.66, p < .01, for abused females. These findings demonstrate how the experience of childhood abuse might disrupt the neurobiology of stress, providing some support for the attenuation hypothesis that victims of abuse may experience cortisol hyposecretion subsequent to a period of heightened secretion.

Developmental pathways from child maltreatment to adolescent pregnancy: A multiple mediational model / Justin RUSSOTTI in Development and Psychopathology, 35-1 (February 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-1 (February 2023) . - p.142-156 Titre : Developmental pathways from child maltreatment to adolescent pregnancy: A multiple mediational model Type de document : Texte imprimé et/ou numérique Auteurs : Justin RUSSOTTI, Auteur ; Sarah A.

NOLL, Auteur Article en page(s) : p.142-156 Langues : Anglais (eng) Mots-clés : adolescent childbirth  adolescent pregnancy  child maltreatment Index. décimale : PER Périodiques Résumé : Adolescent pregnancy (AP) is a significant public health issue. Child maltreatment (CM) represents an established risk factor, yet little is known about the explanatory mechanisms linking the phenomena. Informed by developmental theory, this study prospectively tested seven multi-level, indirect pathways that could plausibly explain the relationship between CM and AP: (1) substance use (polysubstance use and frequency); (2) sexual risk behavior; (3) depressive symptoms; (4) posttraumatic stress disorder symptoms; (5) cognitive dysregulation; (6) pregnancy desire and difficulty expectancies; and (7) age at menarche. Data came from a prospective, longitudinal cohort study of 469 ethnically diverse, nulliparous adolescent females, designed to examine the impact of substantiated CM on reproductive outcomes such as pregnancy and childbirth (265 maltreated and 204 demographically matched comparison adolescents). A multiple-mediator structural equation model was conducted to simultaneously test multiple indirect effects while accounting for confounding variables. Maltreatment had an indirect effect on pregnancy via substance use and higher pregnancy desire/lower perceived difficulty. Findings represent a step towards elucidating pathways linking CM with AP. Recommendations are offered to prevent pregnancy by addressing the pregnancy-specific mechanisms that are part of the maltreatment sequelae.

A longitudinal study of several potential mediators of the relationship between child maltreatment and posttraumatic stress disorder symptoms / Chad E. SHENK in Development and Psychopathology, 26-1 (February 2014)

SHENK, Auteur ; Frank W. PUTNAM, Auteur ; Joseph R. RAUSCH, Auteur ; James L. PEUGH, Auteur ; Jennie G. NOLL, Auteur Article en page(s) : p.81-91 Langues : Français (fre) Index. décimale : PER Périodiques Résumé : Child maltreatment is a reliable predictor of posttraumatic stress disorder (PTSD) symptoms. However, not all maltreated children develop PTSD symptoms, suggesting that additional mediating variables explain how certain maltreated children develop PTSD symptoms and others do not. The current study tested three potential mediators of the relationship between child maltreatment and subsequent PTSD symptoms: (a) respiratory sinus arrhythmia reactivity, (b) cortisol reactivity, and (c) experiential avoidance, or the unwillingness to experience painful private events, such as thoughts and memories. Maltreated (n = 51) and nonmaltreated groups (n = 59) completed a stressor paradigm, a measure of experiential avoidance, and a semistructured interview of PTSD symptoms. One year later, participants were readministered the PTSD symptoms interview. Results of a multiple mediator model showed the set of potential mediators mediated the relationship between child maltreatment and subsequent PTSD symptoms. However, experiential avoidance was the only significant, specific indirect effect, demonstrating that maltreated children avoiding painful private events after the abuse were more likely to develop a range of PTSD symptoms 1 year later. These results highlight the importance of experiential avoidance in the development of PTSD symptoms for maltreated children, and implications for secondary prevention and clinical intervention models are discussed.

The impact of sexual abuse on female development: Lessons from a multigenerational, longitudinal research study / Penelope K. TRICKETT in Development and Psychopathology, 23-2 (May 2011)

TRICKETT, Auteur ; Jennie G. NOLL, Auteur ; Frank W. PUTNAM, Auteur Année de publication : 2011 Article en page(s) : p.453-476 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This is a report on the research design and findings of a 23-year longitudinal study of the impact of intrafamilial sexual abuse on female development. The conceptual framework integrated concepts of psychological adjustment with theory regarding how psychobiological factors might impact development. Participants included 6- to 16-year-old females with substantiated sexual abuse and a demographically similar comparison group. A cross-sequential design was used and six assessments have taken place, with participants at median age 11 at the first assessment and median age 25 at the sixth assessment. Mothers of participants took part in the early assessments and offspring took part at the sixth assessment. Results of many analyses, both within circumscribed developmental stages and across development, indicated that sexually abused females (on average) showed deleterious sequelae across a host of biopsychosocial domains including: earlier onsets of puberty, cognitive deficits, depression, dissociative symptoms, maladaptive sexual development, hypothalamic–pituitary–adrenal attenuation, asymmetrical stress responses, high rates of obesity, more major illnesses and healthcare utilization, dropping out of high school, persistent posttraumatic stress disorder, self-mutilation, Diagnostic and Statistical Manual of Mental Disorders diagnoses, physical and sexual revictimization, premature deliveries, teen motherhood, drug and alcohol abuse, and domestic violence. Offspring born to abused mothers were at increased risk for child maltreatment and overall maldevelopment. There was also a pattern of considerable within group variability. Based on this complex network of findings, implications for optimal treatments are elucidated. Translational aspects of extending observational research into clinical practice are discussed in terms that will likely have a sustained impact on several major public health initiatives.
