There is a need to assess whether the resources invested in building trauma competence in services actually lead to higher levels of competence. For this purpose, we have developed an instrument called the Trauma and Development Education Monitor (TANDEM). The present article presents the process behind developing the instrument and an initial study of its psychometric properties. The tested version consisted of 59 items distributed across the domains of readiness, agency, reflexivity, knowledge, practice and culture at work. Based on responses from 415 professionals in relevant services, concept and criterion validity was examined through reliability analyses, factor analyses and regression analyses. Based on the analyses, the tested version was reduced to 54 items in the final version, distributed across the same six domains. As dimensions, the domains generally showed good scale reliability, and for the final version factor analyses confirmed a one-dimensional model for all domains. The instrument discriminated between respondents who reported more versus less previously received trauma competence building and showed specificity as a measure of trauma versus more general competence. The results indicate that TANDEM has the potential to become a useful tool in endeavours to implement trauma competence in services, as well as in research activities in this field.

Neuroticism Scale

The present aim was to construct and validate the Factorial Arabic Neuroticism Scale. Based on the scales developed by Eysenck, Cattell, and Guilford, the item pool consisted of 226 nonrepeated items. Five Ph.D. referees shortened the pool to 84 items. Then, the item-remainder correlation, the exclusion of the items with significant correlation with scores on Extraversion, and several cycles of factor analyses yielded 20 items representing the final version. The principal components analysis yielded two high-loaded factors of General Neuroticism and Sleep problems and tension. Reliability coefficients alpha ranged from .89 to .94 and between .81 and .91 for test-retest, indicating good internal consistency and temporal stability, respectively. Criterion-related validity ranged between .75 and .79 against scores on the Neuroticism subscale of the NEO-PI–R. Females obtained significantly higher mean scores than males for three of six comparisons (by age) among school and university students ( N = 2,783). An English version is available. The scale may be recommended for use in research, especially on cross-cultural comparisons and for assessing the efficacy of cognitive behavior therapy.

Aim. Health-related quality of life in patients with arterial hypertension (HTN) is still determined by only generic patient-reported outcome measures (PROMs), although disease-specific ones are more reliable and highly valid. Previously, we reported the results of development and item-selection process of the new Russian HTN-specific PROM. The purpose of this last stage was to confirm validity, reliability, responsiveness and sensitivity of the scale and to present its final version.Material and methods. Analysis was done using data from a mass survey of patients with Grades 1-3 HTN (n=359, aged 25 to 91 y. o.) and healthy volunteers (n=48, aged 23 to 65 y.o), 407 returned questionnaires. We conducted two exploratory factor analyses (EFA) with the intermediate version of the PROM (80 questions, 20 of them HTN-specific). The Cattel’s scree test was used to select the optimal number of factors. After removing the items with a low factor loadings, a confirmatory factor analysis (CFA) was performed to assess the model’s fitindexes adequacy. The core indexes to be measured were SRMR, RMSEA, CFI. Finally, the PROM’s reliability (Cronbach’s α and McDonald’s ω) and criterion validity (responsiveness) were evaluated.Results. Both EFA with oblique and varimax rotation showed 35 questions have factor loadings ≥0,5 and assigned to one of 5 factors. The basic structure of the PROM was retained for further CFA. Most of indices of fit measured met the requirements: SRMR was 0,08, RMSEA was 0,07 (90% CI (0,07-0,08)) and CFI was 0,08, which confirms the construct validity. Both Cronbach’s α and MacDonald’s ω of each of the domains were ≥0,80 and the whole scale was 0,89 confirming satisfactory reliability. Scores of the questionnaire were positively correlated with the severity of HTN (p<0,001 for Grades 1-3 HTN) and between HTN and non-HTN patients (p=0,01 and 0,04 in psychologic and social domains respectively).Conclusion. Sequentially addressing of exploratory and confirmatory factor analyses and assessment of reliability and responsiveness allowed to form the final version of the patient-reported outcome measure for arterial hypertension. The new Russian-language questionnaire is a useful and feasible tool for routine practice and clinical trials.

 ABSTRACT  The strategies to reduce overweight and obesity have not had the expected impact. It is necessary to develop greater knowledge regard food estimation and intake frequency. Therefore, the purpose of this study was to examine the psychometric properties of an instrument aimed at the evaluation of meals (EM) and its intake frequency (IFR) in children. A total of 1,090 9-year-old boys and girls from the South region of Jalisco (Mexico) answered the Scale of Estimation of Food and Beverage Intake for Children (EFBI-C), which consists of two sections: EM and IFR. The exploratory factor analysis carried out with 545 participants derived three factors for each section, which were subsequently corroborated based on two confirmatory factor analyses, one per section, performed with the second half of the sample (n = 545). Both models registered some goodness of fit indexes. The final version of the EFBI-C, with 23 items, showed appropriate internal consistency in its both sections: EM (α = .86) and IFR (α = .84). The need to extend the analysis of the psychometric properties of the EFBI-C in children from other regions of the country is discussed. RESUMEN Las estrategias para disminuir el sobrepeso y la obesidad no han tenido el impacto esperado. Se requiere desarrollar mayor conocimiento sobre las variables estimación del alimento y frecuencia de consumo. Por lo tanto, el propósito de este estudio fue examinar las propiedades psicométricas de un instrumento dirigido a evaluar la estimación de alimentos (EAL) y su frecuencia de consumo (FRC) en niños. Participaron 1,090 niños y niñas de 9 años de edad de la región Sur de Jalisco (México), quienes completaron la Escala de Estimación del Consumo de Alimentos y Bebidas para Niños (ECA-N), que consta de dos secciones: EAL y FC. El análisis factorial exploratorio realizado con 545 de los participantes derivó tres factores para cada sección, mismos que posteriormente fueron corroborados con base a dos análisis factoriales confirmatorios, uno por sección, practicados con la segunda mitad de la muestra (n = 545). Ambos modelos registraron adecuados índices de bondad de ajuste. La versión final de la ECA-N, con 23 ítems, mostró poseer adecuada consistencia interna en sus dos secciones: EAL (α = .86) y FRC (α = .84). Se discute sobre la necesidad de extender el análisis de las propiedades psicométricas de la ECA-N en niños de otras regiones del país.

Using immune electron microscopy Feinstone et. al. demonstrated the presence of a 27 nm virus-like particle in acute-phase stools of patients with viral hepatitis, type A, These hepatitis A antigen (HA Ag) particles were aggregated by convalescent serum from patients with type A hepatitis but not by pre-infection serum. Subsequently Dienstag et. al. and Maynard et. al. produced acute hepatitis in chimpanzees by inoculation with human stool containing HA Ag. During the early acute disease, virus like particles antigenically, morphologically and biophysically identical to the human HA Ag particle were found in chimpanzee stool. Recently Hilleman et. al. have described similar particles in liver and serum of marmosets infected with hepatitis A virus (HAV). We have investigated liver, bile and stool from chimpanzees and marmosets experimentally infected with HAV. In an initial study, a chimpanzee (no.785) inoculated with HA Ag-containing stool developed elevated liver enzymes 21 days after exposure.

Dimensional Reconstruction

Structurally-oriented biologists examine cells, tissues, organelles and macromolecules in order to gain insight into cellular and molecular physiology by relating structure to function. The understanding of these structures can be greatly enhanced by the use of techniques for the visualization and quantitative analysis of three-dimensional structure. Three projects from current research activities will be presented in order to illustrate both the present capabilities of computer aided techniques as well as their limitations and future possibilities.The first project concerns the three-dimensional reconstruction of the neuritic plaques found in the brains of patients with Alzheimer's disease. We have developed a software package “Synu” for investigation of 3D data sets which has been used in conjunction with laser confocal light microscopy to study the structure of the neuritic plaque. Tissue sections of autopsy samples from patients with Alzheimer's disease were double-labeled for tau, a cytoskeletal marker for abnormal neurites, and synaptophysin, a marker of presynaptic terminals.
