A systematic review of randomized controlled trials of interventions designed to decrease child abuse in high-risk families.

Child abuse is a global problem, and parents with histories of childhood abuse are at increased risk of abusing their offspring. The objective of this systematic review is to provide a clear overview of the existing literature of randomized controlled trials evaluating the effectiveness of interventions to prevent child abuse. PubMed, PsychINFO, Web of Science, Sociological Abstracts, and CINAHL were systematically searched and expanded by hand search. This review includes all randomized controlled trials (RCTs) of interventions designed to prevent abuse among mothers identified as high-risk. Of the eight studies identified, only three found statistically significant reductions in abuse by any measure, and only two found reductions in incidents reported to child protective services. While much has been written about child abuse in high-risk families, few RCTs have been performed. Only home visitation has a significant evidence base for reducing child abuse, and the findings vary considerably. Also, data from low- and middle-income countries are limited.

Substance use behaviors of secondary school students in post-conflict Liberia: a pilot study

In this study we sought to determine the prevalence of substance use among students in Monrovia, Liberia, in order to better characterize the extent of the problem and guide future research. We conducted a cross-sectional survey to examine the substance use behaviors of students in 16 secondary schools in greater and central Monrovia, Liberia. The sampling frame included all co-educational secondary schools in central and greater Monrovia. A total of 802 students completed the questionnaire. The mean age was 19±3 years. Alcohol was the most commonly used substance, with 51% (399) of respondents reporting using it. Additionally, 9% of all students reported marijuana consumption. Older respondents were more likely to have ever used marijuana. Men were more likely than women to ever consume marijuana and smoke cigarettes. There were no significant differences in gender or age for other drug use. Research has shown that younger people who consume alcohol are more likely to engage in high-risk behavior, such as unprotected sex, early sex or sex with multiple partners, than others their age. Given that the majority of our respondents reported first consuming alcohol before 18 years of age, drug prevention campaigns need to target younger adolescents.

Trauma and traumatic stress in a sample of pregnant women

OBJECTIVE To examine the construct validity of the 9 item Traumatic Events Questionnaire (TEQ) and to evaluate the extent to which experiences of trauma assessed using the TEQ are associated with symptoms of psychiatric disorders among 3342 pregnant women in Lima, Peru. METHODS Symptoms of depression were assessed using the Patient Health Questionnaire-9 (PHQ-9) and Edinburgh Postnatal Depression Scale (EPDS) while the PTSD Checklist-civilian (PCL-C) and Generalized Anxiety Disorder-7 (GAD-7) were used to assess symptoms of PTSD and generalized anxiety. Hierarchical logistic regression procedures were used to evaluate relations between TEQ and symptoms of psychiatric disorders. RESULTS The majority of participants (87.8%) experienced at least one traumatic event (mean = 2.5 events). The trauma occurrence score was moderately correlated with symptoms of PTSD (PCL-C: rho = 0.38, P-value < 0.0001), depression (EPDS: rho = 0.31, P-value < 0.0001; PHQ-9: rho = 0.20, P-value < 0.0001), and GAD (GAD-7: rho = 0.29, P-value < 0.0001). Stronger correlations were observed between the trauma intensity score with symptoms of psychiatric disorders (PCL-C: rho = 0.49, P-value < 0.0001; EPDS: rho = 0.36, P-value < 0.0001; PHQ-9: rho = 0.31, P-value < 0.0001; GAD-7: rho = 0.39, P-value < 0.0001). CONCLUSION Given the high burden of trauma experiences and the enduring adverse consequences on maternal and child health, there is an urgent need for integrating evidence-based trauma informed care programs in obstetrical practices serving Peruvian patients.

Narratives of Agency and Capability from Two Adolescent Girls in Post-conflict Liberia

Between 1989 and 2003, Liberia experienced a brutal civil war characterized by ethnic killings, sexual violence and the use of child soldiers. Five years after the war ended, half the population of Liberia was under 18 years old. Understanding the needs of these youth is thus essential to the recovery of the nation. This study focuses on the narratives of two female adolescents, selected from 75 in-depth individual interviews with post-conflict Liberian youth conducted in 2012. A narrative analysis approach was employed to examine each interview for multiple layers of meaning. The aim of the study was to elucidate factors that may enable post-conflict youth to reclaim a sense of agency and return to normal developmental tasks. The study explores the ways in which these youth navigate complicated power dynamics in the post-conflict setting and how gender impacts their experiences of their own agency and capability. The dynamics between the participants and the interviewer are explored to further illustrate how power dynamics manifest. These narratives support the involvement of youth in projects that help others as an avenue for promoting agency and resilience for themselves.

Suicide risk assessment: examining transitions in suicidal behaviors among pregnant women in Perú

The goals of this research were to characterize suicidal behavior among a cohort of pregnant Peruvian women and identify risk factors for transitions between behaviors. The World Health Organization Composite International Diagnostic Interview suicide questionnaire was employed to assess suicidal behavior. Discrete-time survival analysis was used to study the cumulative age-of-onset distribution. The hazard function was calculated to assess the risk of onset of each suicidal behavior. Among 2062 participants, suicidal behaviors were endorsed by 22.6% of participants; 22.4% reported a lifetime history of suicidal ideation, 7.2% reported a history of planning, and 6.0% reported attempting suicide. Childhood abuse was most strongly associated with suicidal behavior, accounting for a 2.57-fold increased odds of suicidal ideation, nearly 3-fold increased odds of suicide planning, and 2.43-fold increased odds of suicide attempt. This study identified the highest prevalence of suicidal behavior in a population of pregnant women outside the USA. Diverse populations of pregnant women and their patterns of suicidal behavior transition must be further studied. The association between trauma and suicidal behavior indicates the importance of trauma-informed care for pregnant women.

The psychometric properties of the 16-item version of the Prodromal Questionnaire (PQ-16) as a screening instrument for perinatal psychosis

Psychiatric illness can pose serious risks to pregnant and postpartum women and their infants. There is a need for screening tools that can identify women at risk for postpartum psychosis, the most dangerous perinatal psychiatric illness. This study used exploratory factor analysis (EFA) and Rasch item response theory (IRT) models to evaluate the psychometric properties and construct validity of the Spanish language version of the 16-item Prodromal Questionnaire (PQ-16) as a screening tool for psychosis in a population of pregnant Peruvian women. The EFA yielded a four-factor model, which accounted for 44% of the variance. Factor 1, representing “unstable sense of self,” accounted for 22.1% of the total variance; factor 2, representing “ideas of reference/paranoia,” for 8.4%; factor 3, representing “sensitivity to sensory experiences,” accounted for 7.2%; and factor 4, possibly representing negative symptoms, accounted for 6.3%. Rasch IRT analysis found that all of the items fit the model. These findings support the construct validity of the PQ-16 in this pregnant Peruvian population. Also, further research is needed to establish definitive psychiatric diagnoses to determine the predictive power of the PQ-16 as a screening tool.
