Psychosocial risk factors for suicidality in children and adolescents

Suicidality in childhood and adolescence is of increasing concern. The aim of this paper was to review the published literature identifying key psychosocial risk factors for suicidality in the paediatric population. A systematic two-step search was carried out following the PRISMA statement guidelines, using the terms 'suicidality, suicide, and self-harm' combined with terms 'infant, child, adolescent' according to the US National Library of Medicine and the National Institutes of Health classification of ages. Forty-four studies were included in the qualitative synthesis. The review identified three main factors that appear to increase the risk of suicidality: psychological factors (depression, anxiety, previous suicide attempt, drug and alcohol use, and other comorbid psychiatric disorders); stressful life events (family problems and peer conflicts); and personality traits (such as neuroticism and impulsivity). The evidence highlights the complexity of suicidality and points towards an interaction of factors contributing to suicidal behaviour. More information is needed to understand the complex relationship between risk factors for suicidality. Prospective studies with adequate sample sizes are needed to investigate these multiple variables of risk concurrently and over time

Protocol for assessing feasibility, acceptability and fidelity of screening for antenatal depression (FAFSAD) by midwives in Blantyre District, Malawi

Depression is often underdiagnosed by treating health professionals. This is a situation in Malawi where there is no routine screening of depression at antenatal clinics. Recently, a Screening Protocol for Antenatal Depression (SPADe) that can be used by midwives to screen for antenatal depression was developed in Blantyre District. SPADe proposes multistage screening of antenatal depression by midwives which may enable early detection and treatment of pregnant women with depression. Proper treatment of antenatal depression can assist in achieving Sustainable Development Goals (SDGs). However, utilisation of SPADe in clinical practice to screening for depression in antenatal clinics has not been established yet. Therefore, the primary aim of this study is to assess feasibility of screening for depression by midwives using SPADe in antenatal clinics in Blantyre District. The secondary aim was to assess acceptability and fidelity of screening for depression by midwives using SPADe in antenatal clinics in Blantyre District

Maternal depression and mental health in early childhood: an examination of underlying mechanisms in low-income and middle-income countries.

Studies examining mechanisms underlying associations between maternal depression and adverse child outcomes (including behaviour, socioemotional adjustment, and emotion regulation) indicate that during pregnancy, maternal depression could affect child outcomes through altered placental function, epigenetic changes in the child, and stress reactivity. Infection and dietary deficiencies in the mother and the child, together with the child's genetic vulnerability, might also affect outcome. Postnatally, associations between maternal depression and child outcome are influenced by altered mother-child interactions, sociodemographic or environmental influences, and social support. Knowledge is scarce on mechanisms in low-income and middle-income countries where maternal depression is highly prevalent, and stressful factors that influence the development of perinatal maternal depression and adverse child outcome (eg, food insecurity, perinatal infections, crowded or rural living conditions, and interpersonal violence) are both more intense and more common than in high-income countries. We reviewed evidence and use the biopsychosocial model to illustrate risk factors, mediators and moderators underlying associations between maternal depression and child outcomes in low-income and middle-income countries

Conscious and nonconscious discrimination of facial expressions

Abrupt discontinuities in recognizing categories of emotion are found for the labelling of consciously perceived facial expressions. This has been taken to imply that, at a conscious level, we perceive facial expressions categorically. We investigated whether the abrupt discontinuities found in categorization for conscious recognition would be replaced by a graded transition for subthreshold stimuli. Fifteen volunteers participated in two experiments, in which participants viewed faces morphed from 100% fear to 100% disgust along seven increments. In Experiment A, target faces were presented for 30 ms, in Experiment B for 170 ms. Participants made two-alternative forced-choice decisions between fear and disgust. Results for the 30 ms presentation time indicated a significant linear trend between degree of morphing and classification of the images. Results for 170 ms presentation time followed the higher order function found in studies of categorical perception. These results provide preliminary evidence for separate processes underlying conscious and nonconscious perception of facial expressions of emotion
