Retrospective assessment of adverse childhood experiences is widely used in research, although there are concerns about its validity. In particular, recall bias is assumed to produce significant artifacts. Data from a longitudinal cohort (the British National Child Development Study; N = 7,710) and the retrospective Mainz Adverse Childhood Experiences Study ( N = 1,062, Germany) were compared on 10 adverse childhood experiences and psychological adjustment at age 42 yr. Between the two methods, no significant differences in risk effects were detected. Results held for bivariate analyses on all 10 childhood adversities and a multivariate model; the later comprises the childhood adversities which show significant long-term sequelae (not always with natural parent, chronically ill parent, financial hardship, and being firstborn) and three covariates. In conclusion, the present data did not show any bias in the retrospective assessment.

Control of human African trypanosomiasis (HAT) in the Democratic Republic of Congo is based on mass population screening by mobile teams; a costly and labor-intensive approach. We hypothesized that blood samples collected on filter paper by village health workers and processed in a central laboratory might be a cost-effective alternative. We estimated sensitivity and specificity of micro-card agglutination test for trypanosomiasis (micro-CATT) and enzyme-linked immunosorbent assay (ELISA)/T.b. gambiense on filter paper samples compared with parasitology-based case classification and used the results in a Monte Carlo simulation of a lot quality assurance sampling (LQAS) approach. Micro-CATT and ELISA/T.b. gambiense showed acceptable sensitivity (92.7% [95% CI 87.4-98.0%] and 82.2% [95% CI 75.3-90.4%]) and very high specificity (99.4% [95% CI 99.0-99.9%] and 99.8% [95% CI 99.5-100%]), respectively. Conditional on high sample size per lot (> or = 60%), both tests could reliably distinguish a 2% from a zero prevalence at village level. Alternatively, these tests could be used to identify individual HAT suspects for subsequent confirmation.
