RESUMO
Associations between psychotic experiences and suicidal ideation are not yet fully understood, and the potential role of depressive symptoms in this relationship remains unclear. The current study examined relationships between depressive symptoms (DS), psychotic experiences (PE) and suicidal ideation (SI) using two complementary approaches on cross-sectional data from a community sample of adolescents aged 13-19 years (N = 1,591). First, we investigated the association between the three domains using mediation analysis, showing that depressive symptoms partly mediate the relationship between psychotic experiences and suicidal ideation. Second, we looked at associations between the three domains at item level using network analysis. Specific associations between symptoms of the three domains were found, indicating depressive symptoms of sadness, avolition, pessimism, and self-criticalness/worthlessness as the most central symptoms in the network. Suicidal ideation was associated with the depressive symptoms pessimism and worthlessness, to social anxiety, and to perceptual anomalies. Our results show that the mediating effect of depressive symptoms between psychotic experiences and suicidal ideation may be due to associations between specific aspects of SI, depressive symptoms and psychotic experiences. These findings can contribute to the planning of health services and programs aimed at the timely detection of psychopathology and suicidal risk in young people.
RESUMO
Latinos are the largest growing population and have the highest fertility rates in the US. In response, this study assessed if late initiation of or no prenatal care (PNC) mediated the relationship among adverse birth outcomes and interactions between immigrant and insurance status. This study used cross-sectional data (2002-2004) limited to 109,399 women of Mexican ethnicity who had singleton births in the San Joaquin Valley, California. We conducted hierarchical mediation analyses. US-born Mexican women who used private or public insurance for PNC were more likely to have infants born at low-birth weight and premature compared to Mexican first generation immigrant women. Nonetheless, initiation of late or no PNC positively mediated the relationship between infants born premature to Mexican first generation immigrant women who used public insurance (ab/se(ab) = 2.123, p = .034). Findings from this study support acculturation theory and the need for multilevel approaches to address PNC among women of Mexican ethnicity.
