RESUMO
Our aim was to assess personality traits associated with substance use during pregnancy in a population-based, multicentre study of 1804 pregnant women. On day 2-3 postpartum, participants completed a semi-structured interview, including self-reported drug use (alcohol, tobacco, caffeine, cannabis, cocaine, opioids) during pregnancy, and socio-demographic, reproductive and obstetric variables, personal and family psychiatric history, social support, and the Eysenck personality questionnaire, short version (EPQ-RS). Logistic regression models were conducted. Fifty per cent of women reported substance use during pregnancy: 40% caffeine, 21% tobacco, 3.5% alcohol, and 0.3 % cannabis. Mean T-scores (SD) for personality dimensions were 51.1 (9.6) for extraversion, 48 (8.9) for psychoticism, and 43.6 (8.5) for neuroticism. Extroversion (p = .029) and psychoticism (p = .009) were identified as risk factors after adjustment by age, level of education, employment status during pregnancy, low social support, and previous psychiatric history. For each increment of 10 units in their scores, the odds of substance use increased by 12% and 16% respectively. Low education, being on leave during pregnancy, and previous psychiatric history were independent factors (p < .05) associated with substance use during pregnancy. Primiparity was a protective factor (p = .001). The final models showed a good fit (p = .26). The screening of substance use during pregnancy should include personality dimensions apart from psychosocial variables and history of psychiatric disorders. It is important to identify the associated risk factors for substance use during pregnancy to prevent and improve foetal/neonatal and maternal health during perinatal period.
Este estudio evalúa los patrones de consumo de substancias durante el embarazo y las dimensiones de personalidad asociadas, en una muestra multicéntrica de 1804 mujeres de población general. En el 2-3 día posparto, completaron una entrevista auto-administrada sobre el consumo de alcohol, tabaco, cafeína, cannabis, cocaína, opiáceos, drogas de diseño, además de variables socio-demográficas, obstétricas/reproductivas, historia psiquiátrica previa, apoyo social durante el embarazo y el cuestionario de personalidad de Eysenck (EPQ-RS). Se generaron modelos de regresión logística múltiple. La prevalencia del consumo fue del 50% (N=909): 40% cafeína, 21% tabaco, 3,5% alcohol, y 0,3 cannabis. Las puntuaciones T medias (DE) de personalidad fueron: extraversión 51,1 (9,6), psicoticismo 48 (8,9) y neuroticismo 43,6 (8,5). Las dimensiones de extraversión (p=0,029) y psicoticismo (p=0,009), fueron identificadas como factores de riesgo tras ajustar por edad, nivel educación, estatus laboral durante el embarazo, bajo apoyo social, e historia psiquiátrica previa. Para cada incremento de 10 unidades en sus puntuaciones, el odds de consumo de substancias durante el embarazo se incrementó un 12% y un 16% respectivamente. Menor educación, estar de baja, y antecedentes psiquiátricos fueron también factores independientes (p<0,05) asociados al consumo. Ser primípara fue factor protector (p=0,001). El modelo final mostró un ajuste satisfactorio (p=0,26). El cribaje de las mujeres con riesgo de consumo de substancias durante el embarazo debería incluir la personalidad además de variables psicosociales y antecedentes psiquiátricos. Identificar los factores de riesgo asociados es importante para prevenir y mejorar la salud materna y fetal/neonatal durante el embarazo y posparto.
RESUMO
BACKGROUND AND OBJECTIVES: To validate four instruments to detect domestic violence in health-care settings against external criteria -Index of Spouse Abuse (ISA), Psychological Maltreatment of Women Inventory short form (PMWI-SF), Woman Abuse Screening Tool (WAST), Partner Violence Screen (PVS)- and to assess the concordance and compare the diagnostic accuracy. SUBJECTS AND METHOD: This was a case-control study. The study sample was recruited from primary care and domestic violence centers. The ISA, PMWI-SF, WAST and PVS were administered to 223 controls and 182 intimate partner violence cases. Received Operating Characteristic (ROC) curve analysis was carried out. Measures were compared in terms of ROC curves and overall agreement. RESULTS: The areas under the curve (AUC) were: ISA 0.99 (IC 95%, 0.98-0.99), PMWI-SF 0.98 (IC 95% 0.97-0.99), WAST 0.95 (IC 95% 0.93-0.97), PVS 0.91 (IC 95% 0.87-0.94). The overall agreement between the four tools was excellent (Fleiss Kappa=0.82). The ISA and the PMWI-SF performed slightly better than WAST, and these three instruments performed better than PVS for detecting domestic violence. The PVS had lower concordance values with the other instruments. CONCLUSIONS: The four instruments demonstrated adequate diagnostic accuracy and overall agreement for detect domestic violence. Some overestimation of sensitivity may occur due to different source of cases.
