Two studies of assault victims examined the roles of (a) disorganized trauma memories in the development of posttraumatic stress disorder (PTSD), (b) peritraumatic cognitive processing in the development of problematic memories and PTSD, and (c) ongoing dissociation and negative appraisals of memories in maintaining symptomatology. In the cross-sectional(More)
BACKGROUND We have previously reported higher and more variable salivary morning cortisol in 13-year-old adolescents whose mothers were depressed in the postnatal period, compared with control group adolescents whose mothers did not develop postnatal depression (PND). This observation suggested a biological mechanism by which intrafamilial risk for(More)
OBJECTIVE There were two aims to this study: first to examine whether emotional abuse and neglect are significant predictors of psychological and somatic symptoms, and lifetime trauma exposure in women presenting to a primary care practice, and second to examine the strength of these relationships after controlling for the effects of other types of(More)
Recent studies have shown that rumination is a powerful predictor of persistent posttraumatic stress disorder (PTSD). However, to date, the mechanisms by which rumination maintains PTSD symptoms are little understood. Two studies of assault survivors, a cross-sectional (N = 81) and a 6-month prospective longitudinal study (N = 73), examined several facets(More)
Among the adverse mental health consequences of childhood trauma is the risk related to the development of posttraumatic stress disorder (PTSD) in adulthood. Other risk factors for PTSD. including parental trauma exposure and parental PTSD, can also contribute to the experience of child trauma. We examined associations between childhood trauma and PTSD in(More)
BACKGROUND Because alterations in cortisol negative feedback inhibition associated with aging are generally opposite of those observed in posttraumatic stress disorder (PTSD), we examined the cortisol and glucocorticoid receptor (GR) response to dexamethasone (DEX) in older trauma survivors. METHODS Twenty-three Holocaust survivors (9 men, 14 women), 27(More)
BACKGROUND Maternal postnatal depression (PND) has been associated with adverse outcomes in young children, but an association with longer-term psychiatric disorder has not been demonstrated. We present the preliminary findings of a 13-year longitudinal study. METHODS In the course of a prospective longitudinal study, we examined DSM-IV Axis I disorders(More)
OBJECTIVE The aim of this study was to determine the developmental risk pathway to depression by 16 years in offspring of postnatally depressed mothers. METHOD This was a prospective longitudinal study of offspring of postnatally depressed and nondepressed mothers; child and family assessments were made from infancy to 16 years. A total of 702 mothers(More)
Memory deficits are implicated in the development of posttraumatic stress disorder (PTSD). Intentional recall of trauma memories is frequently disorganised or incomplete, whilst involuntary memory fragments are easily triggered by perceptual cues. Ehlers and Clark (Behaviour Research and Therapy 38 (2000) 319-345) propose that a predominance of data-driven(More)
OBJECTIVE Enhanced negative feedback and reduced adrenal output are two different models that have been put forth to explain the paradoxical observations of increased release of corticotropin-releasing factor in the face of low cortisol levels in posttraumatic stress disorder (PTSD). To discriminate between these models, the authors measured levels of(More)
