The aims were to study the validity and test-retest reliability of the Early Trauma Inventory-Self Report (ETI-SR) and its short-form (ETI-SF), which retrospectively assess different childhood trauma, in a sample of Spanish postpartum women. A total of 227 healthy postpartum women completed the ETI-SR and ETI-SF. The longitudinal, expert, all data procedure was used as the external criterion for the assessment of childhood trauma. The ETI-SR and ETI-SF were also administered to a sample of 102 postpartum depressive women (DSM-IV) and the results were compared with those of the healthy postpartum sample. The area under the curve values of the ETI-SR and ETI-SF were 0.77 (95% confidence interval [CI], 0.71-0.84) and 0.78 (95% CI, 0.72-0.85), the internal consistencies of the 2 scales were 0.79 and 0.72, and the intraclass correlation coefficients were 0.92 (95% CI, 0.80-0.97) and 0.91 (95% CI, 0.78-0.96), all respectively. The ETI-SR and ETI-SF had higher test-retest reliability on all subscales. The ETI-SR and ETI-SF are shown to be valid and reliable instruments for assessing childhood trauma in postpartum women.

    ABSTRACT: Childhood abuse is a powerful risk factor for developing postpartum depression in adulthood, and recently it has been associated to thyroid dysfunction in postpartum depressive women. The purpose of this study was to investigated the effects of childhood abuse on thyroid status and depressive symptomatology in two hundred and thirty-six (n=236) postpartum women 24-48h after delivery. The Early-Trauma-Inventory Self-Report was used to assess the presence of childhood abuse and the Edinburgh Postpartum Depression Scale (EPDS) to evaluate depressive symptomatology (EPDS≥11). Free thyroxin (fT4) and thyroid-stimulating hormone (TSH) were measured. Thyroid dysfunction (TD) was defined as altered TSH or TSH and fT4. Socio-demographic, reproductive, and psychopathological variables were also collected. Multivariate analysis shows that childhood physical abuse increases by four times the risk for TD (OR: 3.95, 95% CI: 1.23-12.71) and five times the risk for depressive symptomatology (OR: 5.45, 95% CI: 2.17-13.66) in the earlier postpartum. Our findings suggest that women with history of childhood physical abuse are particularly at-risk for thyroid dysfunction and depressive symptomatology 24-48h after delivery. The assessment of childhood abuse in the perinatal period is important to identify women at-risk for physical and mental health problems in this period.

    ABSTRACT: The aim of this study was to examine the relationship between intimate partner violence (IPV) and personality disorder symptoms controlling for depressive state. Victims of IPV (n = 176) and non-abused women (n = 193) completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), Index of Spouse Abuse (ISA), and Beck Depression Inventory-II (BDI-II). IPV victims scored higher than non-abused women on Intimacy Problems, and scored lower on Rejection traits, after adjustment for depressive symptoms. Severity of the IPV was related to Cognitive Distortion, Suspiciousness, Restricted Expression, and Intimacy Problems, and the length of the IPV was negatively associated with Rejection. The current study suggests only modest differences in personality traits between IPV and non-abused women. The DAPP-BQ traits associated with severity of IPV, in a dose-response manner, would partially reflect the symptoms of complex post-traumatic stress disorder (CPTSD), although this possibility deserves further study.

    ABSTRACT: Previous studies suggest a different regulation of the hypothalamus-pituitary-adrenal axis (HPA-axis) with lower diurnal cortisol levels, especially in the morning, in children with attention-deficit/hyperactivity disorder (ADHD) compared with controls. Since exposure to foetal and childhood psychosocial adversity has been associated with both ADHD and HPA-axis functioning, such exposures may explain these low cortisol levels in ADHD via early programming of the HPA-axis. Thus, our main aim was to retrospectively study foetal and early childhood exposures to psychosocial adversity in children with ADHD and to relate these exposures to cortisol levels. Saliva samples were collected during a regular weekday in children, 6-17 years old, with clinically confirmed ADHD (n = 197) and non-affected comparisons (n = 221) for radioimmunoassay analysis of cortisol. Parental rating scales were used for categorising subtypes of ADHD and degree of exposure to adversity. Children with ADHD had more reports of at least one rated foetal adversity (p = 0.041) and childhood adversity (p < 0.001) than comparisons. The association between low morning cortisol levels and ADHD-symptoms remained when analyses were adjusted for adversities, age, sex, sampling time and symptoms of oppositional defiant disorder. No relation was found between exposures to foetal/childhood adversity and cortisol levels except for a positive relation between childhood adversity and cortisol morning increase in children with ADHD. The hypothesis that early adversity may influence the HPA-axis, leading to lower cortisol levels in children with ADHD, was not supported by our findings.
