Study design of 'FRIENDS for Life': process and effect evaluation of an indicated school-based prevention programme for childhood anxiety and depression

Background: Anxiety disorders and depression are highly prevalent in children and affect their current and future functioning. 'FRIENDS for Life' is a cognitive-behavioural programme teaching children skills to cope more effectively with feelings of anxiety and depression. Although 'FRIENDS for Life' is increasingly being implemented at Dutch schools, its effectiveness as a preventive intervention in Dutch schools has never been investigated. The aim of the study is to evaluate the effectiveness of 'FRIENDS for Life' as an indicated school-based prevention programme for children with early or mild signs of anxiety or depression. Methods/Design. This study is a controlled trial with one pre-intervention and three post-intervention measurements (directly after, and 6 and 12 months after the end of the programme). The study sample consists of children aged 10-12 years (grades 6, 7 and 8 of Dutch primary schools), who show symptoms of anxiety or depressive disorder. Data are collected through self-report, teacher report and peer nomination. A process evaluation is conducted to investigate programme integrity (whether the programme has been executed according to protocol) and to evaluate children's and parents' opinions about 'FRIENDS for Life' using online focus groups and interviews. Discussion. The present study will provide insight into the effectiveness of 'FRIENDS for Life' as an indicated school-based prevention programme for children with early or mild signs of anxiety or depression

Search for gravitational waves associated with gamma-ray bursts detected by Fermi and Swift during the LIGO–Virgo run O3b

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC–2020 March 27 17:00 UTC). We conduct two independent searches: a generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence for subthreshold gravitational-wave signals associated with this GRB ensemble either. We use several source types and signal morphologies during the searches, resulting in lower bounds on the estimated distance to each GRB. Finally, we constrain the population of low-luminosity short GRBs using results from the first to the third observing runs of Advanced LIGO and Advanced Virgo. The resulting population is in accordance with the local binary neutron star merger rate

Effect of Antimalarial Drugs on Plasmodia Cell-Free Protein Synthesis

A cell-free system from Plasmodium falciparum able to translate endogenous mRNA was used to determine the effect of artemisinin, chloroquine and primaquine on the protein synthesis mechanism of the parasite. The antimalarial drugs did not inhibit the incorporation of [³H] methionine into parasite proteins even at concentrations higher than the ones found to strongly inhibit the parasite growth. Results clearly indicate that these compounds do not have a direct effect on protein synthesis activity of P. falciparum coded by endogenous mRNA

Using the FRIENDS Programs to Promote Resilience in Cross-Cultural Populations

Childhood and adolescence is a time of rapid biological, psychological, and social growth. Prevalence rates around the world currently estimate approximately one in five adolescents experience mental health difficulties. As factors are increasingly implicated in the etiology of behavioral and emotional difficulties, clinicians and researchers have identified the need for resilience-enhancing prevention programs. The current authors redefine resilience as not only being able to navigate towards and negotiate for resources in the face of adversity, but also to embrace positive life challenges. This chapter discusses protective and risk factors of emotional well-being in youths to provide a framework for the development of resilience-building programs. A brief review of resilience enhancement in youths is provided as well as introduction to the FRIENDS protocol, four socio-emotional skills programs. The FRIENDS programs are robustly supported and the only program endorsed by the World Health Organization for the prevention and treatment of anxiety and depression in children and youth (Prevention of mental disorders: Effective interventions and policy options, Geneva, Switzerland, 2004). Description of the FRIENDS programs, research evaluating intervention outcomes, and strategies to adapt techniques for use in diverse youth populations are also included. Lastly, recent innovations in conceptualization, research, assessment, and treatment of resilience as well as future directions for research are discussed
