Psychological distress among primary school teachers: a comparison with clinical and population samples.

OBJECTIVES: This analysis explored the level of psychological distress among primary school teachers in the South West of England as compared with clinical and general population samples. STUDY DESIGN: Secondary analysis of data from the Supporting Teachers and Children in Schools (STARS) trial completed by up to 90 teachers at baseline, 9, 18 and 30 months of follow-up. METHODS: We used the Everyday Feelings Questionnaire (EFQ) as a measure of psychological distress. Baseline data on teachers were compared with a population sample of professionals and a clinical sample of patients attending a depression clinic. RESULTS: Our teacher cohort experienced higher levels of psychological distress than comparable professionals from the general population, which were sustained over 30 months of follow-up. Levels of psychological distress were lower than those found in the clinical sample. Using a cut-point indicative of moderate depression, our data suggest that between 19% and 29% of teachers experienced clinically significant distress at each time-point. CONCLUSIONS: We detected high and sustained levels of psychological distress among primary school teachers, which suggests an urgent need for intervention. Effective support for teachers' mental health is particularly important given the potential impact of poor teacher mental health on pupil well-being, pupil attainment and teacher-pupil relationships.

Trypanosomatids are common and diverse parasites of Drosophila.

Drosophila melanogaster is an important model system of immunity and parasite resistance, yet most studies use parasites that do not naturally infect this organism. We have studied trypanosomatids in natural populations to assess the prevalence and diversity of these gut parasites. We collected several species of Drosophila from Europe and surveyed them for trypanosomatids using conserved primers for two genes. We have used the conserved GAPDH sequence to construct a phylogenetic tree and the highly variable spliced leader RNA to assay genetic diversity. All 5 of the species that we examined were infected, and the average prevalence ranged from 1 to 6%. There are several different groups of trypanosomatids, related to other monoxenous Trypanosomatidae. These may represent new trypanosomatid species and were found in different species of European Drosophila from different geographical locations. The detection of a little studied natural pathogen in D. melanogaster and related species provides new opportunities for research into both the Drosophila immune response and the evolution of hosts and parasites.
