BACKGROUND Very little is known about the prevalence of neurological morbidity in Africa. Much of this is due to the difficulty in performing epidemiological surveys in these settings. A screening instrument to measure neurological disease in resource-poor settings was designed by the World Health Organization in 1981, but several problems with it have subsequently been recognized. METHODS We...

Research conducted with adult samples suggests that anxiety sensitivity is positively related to depression (Otto et al., 1995, Journal of Anxiety Disorders, 10, 117-123). The Childhood Anxiety Sensitivity Index (CASI, Silverman et al., 1991, Journal of Clinical Child Psychology, 20 162-168) was used in this study to provide an examination of the relation between anxiety, anxiety sensitivity, a...

This study examined the factor structure, reliability, and validity of the German translation of the Childhood Anxiety Sensitivity Index (CASI). A total of 1292 adolescents participated in the study. Analyses using the Schmid-Leiman solution showed the CASI to have one higher order factor and three orthogonal lower order factors. CASI scores correlated significantly with anxiety symptoms and wi...

Measurements of the sound velocities in a single crystal of MnSi were performed in the temperature range 4-150 K. Elastic constants, controlling propagation of longitudinal waves, reveal significant softening at a temperature of about 29.6 K and small discontinuities at ∼28.8 K, which corresponds to the magnetic phase transition in MnSi. In contrast, the shear elastic moduli do not show any sof...

BACKGROUND Interviewer-administered surveys are an important method of collecting population-level epidemiological data, but suffer from declining response rates and increasing costs. Web surveys offer more rapid data collection and lower costs. There are concerns, however, about data quality from web surveys. Previous research has largely focused on selection biases, and few have explored meas...
