Background: Research on the mental health of homicidally bereaved children and young people is scarce. Despite the importance of timely referral of those at risk of developing severe mental health problems, few convincing risk factors have been identified. The effectiveness of current treatment models is unclear.

Background: Childhood maltreatment is a risk factor for developing multiple forms of psychopathology, including depression, posttraumatic stress disorder (PTSD), and anxiety. Yet, the mechanisms linking childhood maltreatment and these psychopathologies remain less clear.

Objective: Here we examined whether self-stigma, the internalization of negative stereotypes about one's experiences, mediates the relationship between childhood maltreatment and symptom severity of depression, PTSD, and anxiety.

Background: Losing a family member during childhood is a potentially traumatic event and increases the risk of mental health difficulties. Adolescents have the right to express their views in research of relevance to them, but few studies have involved bereaved adolescents as collaborators (i.e. Patient and Public Involvement (PPI)). Furthermore, to ensure meaningful and non-tokenistic involvement, bereaved adolescents’ levels of participation and experiences of taking part in research need to be evaluated.

Objective: Asylum seekers often experience ethnic discrimination on the flight or in the host country, which may be associated with chronic stress and impaired mental health. Dysregulation of the hypothalamic–pituitary–adrenal axis, a known physiological correlate of chronic stress, can be assessed using hair cortisol concentrations (HCC). The present study aimed to investigate how different forms of perceived ethnic discrimination are associated with mental health outcomes, HCC, and protective factors in asylum seekers living in Germany.
