Climate change has become a global emergency, which mental health effects are increasingly being described and understood. Children and adolescents, especially those in low income countries and minority communities, are particularly vulnerable to experience the worst impacts of climate change now and in the coming decades. Our group of early career mental health clinicians and researchers in nine culturally and socioeconomic different countries across three continents initiated a global, online discussion about the effects of climate change on the mental health of children and adolescents, based on literature and our professional experience. We identified a paucity of research and psychiatric education on the topic, and a need to advance global and local efforts in this direction. We also identified three main domains of mental health impact of climate change: direct, indirect, and through physical conditions. Our work offers a preliminary, up-to-date overview of the consequences of climate change on the mental health of children and adolescents, and provides recommendations to advance policies, public health efforts, research, education, and clinical care in the emerging area of 'Climate Psychiatry'.

Attention-Deficit Hyperactivity Disorder (ADHD) is a complex and heterogeneous neurodevelopmental condition for which curative treatments are lacking. Whilst pharmacological treatments are generally effective and safe, there is considerable inter-individual variability among patients regarding treatment response, required dose, and tolerability. Many of the non-pharmacological treatments, which are preferred to drug-treatment by some patients, either lack efficacy for core symptoms or are associated with small effect sizes. No evidence-based decision tools are currently available to allocate pharmacological or psychosocial treatments based on the patient's clinical, environmental, cognitive, genetic, or biological characteristics. We systematically reviewed potential biomarkers that may help in diagnosing ADHD and/or stratifying ADHD into more homogeneous subgroups and/or predict clinical course, treatment response, and long-term outcome across the lifespan. Most work involved exploratory studies with cognitive, actigraphic and EEG diagnostic markers to predict ADHD, along with relatively few studies exploring markers to subtype ADHD and predict response to treatment. There is a critical need for multisite prospective carefully designed experimentally controlled or observational studies to identify biomarkers that index inter-individual variability and/or predict treatment response.

Violence-related post-traumatic stress disorder (PTSD) in the context of war and terrorism has become an increasingly pressing public health issue relevant to refugee children and families. PTSD and related psychopathology in children can adversely affect all domains of development and, in particular, interfere with learning and socialization. When the experience of violent trauma and related loss is shared with the entire family, resulting impairment and distress may prevent caregivers from being psychologically available to process their traumatized children's emotional communication and otherwise meet their children's developmental needs. When children suffer from PTSD, it may be impossible to put their experience and related thoughts and feelings into words, let alone a coherent narrative. The latter difficulty can be even more pronounced when the child displays dissociative symptoms, possibly signaling a dissociative subtype of PTSD. Thus, the narrative within the child's play during psychotherapy becomes all the more important as an indicator of the child's internal world. This case report is an example both of evaluation and of psychotherapy that is both psychodynamic and trauma-informed with a 10-year-old Afghani boy who suffered the violent loss of his father at age of 3 years, leading to his immigration to Switzerland. This paper addresses the question of how the psychotherapist can accompany the child through the elaboration of his trauma and how the therapist can contribute to the co-construction of a coherent narrative of the child's experience and to the restoration of an intersubjective connection between the traumatized child and caregiver.

Sexual minority men (SMM) are at increased risk for mental health problems due to effects of sexual minority stigma (e.g., internalized homonegativity (IH)). Both IH and emotion dysregulation are contributors to sexual compulsivity; however, the role of feelings of sexual shame have not been examined in this association. A sample of 982 HIV-negative SMM completed online surveys (Mage = 42.4, SD = 13.74). Path analyses indicated significant direct effects of IH on sexual shame (β = 0.44, p < .001), emotion dysregulation (β = 0.19, p < .001), and sexual compulsivity (β = 0.22, p < .001). Modeled simultaneously, the association between sexual shame and sexual compulsivity (β = 0.26, p < .001) was significant, as was the association between emotion dysregulation and sexual compulsivity (β = 0.27, p < .001). Finally, an indirect effect of IH on sexual compulsivity through both sexual shame (p < .001) and emotion dysregulation (p < .001) was significant, and the association between IH and sexual compulsivity was reduced to non-significant (β = 0.01, p = .74). Targeting feelings of sexual shame and emotion dysregulation in clinical interventions may help reduce the negative health impact of sexual compulsivity among SMM.
