In this era of increasing accountability in health care there is a need for an easily administered reliable instrument to assess the outcome of patients treated for psychiatric illness. This need has been reviewed comprehensively by Andrews et al [1]. One of the several instruments they recommended was the Health of the Nation Outcome Scale instrument (HoNOS) [2,3]. This paper describes the introduction of the HoNOS in a private hospital setting.

Important Activity

Background: Pretesting a questionnaire is an important activity before the start of the main epidemiological study.Aim: The study tested the reliability (internal consistency) of the modified ATS-DLD-78 adult respiratory diseases questionnaire developed by the British Medical Research Council.Results: The questionnaire was found to be reliable and admissible with an overall Cronbach’s alpha coefficient of α = 0.74.Conclusion: The questionnaire is a reliable instrument for data collection and can be a useful tool for collecting data in a developing country. The questionnaire will be used to study the association between respiratory and cardiovascular diseases among older people and community’s proximity to mine dumps

This article addresses the process of designing and validating a questionnaire on the New Water Culture, which aims to collect information on various issues related to water, such as its management, savings, and consumption. The questionnaire was subjected to a double validation process: an evaluation by a panel of experts, including members of the New Water Culture Foundation, and a pilot study, which allowed us to estimate the validation of the content as well as the corresponding internal consistency of the questionnaire. The construction and validation process resulted in a questionnaire consisting of 27 items with a total of 71 variables distributed in four sections: the first is related to scarcity, quantity, and distribution of water; the second collects questions about the different dimensions of water; the third analyses the different ways of carrying out water management; and the fourth and last section is related to personal actions associated with water. The reliability study showed a Cronbach alpha of 0.913, which demonstrates the development of a robust and reliable instrument allowing the identification of the most problematic issues associated with the New Water Culture.

El objetivo de este estudio fue diseñar y validar un instrumento para analizar las decisiones de programación de los contenidos del entrenamiento en balonmano. El proceso de construcción y validación siguió cuatro fases: diseño del instrumento por un grupo de discusión, validación del contenido por 11 expertos (Método Delphi), validación de comprensión por 23 entrenadores y estudio piloto con 30 entrenadores para evaluar la consistencia interna (alfa de Cronbach) y la validez de constructo (asociación entre las decisiones de programación y el número de años de experiencia como entrenador sénior). La validación por expertos permitió definir un instrumento con 52 cuestiones, con un nivel de comprensión adecuado. El alfa de Cronbach fue superior a 0.95 en todas las dimensiones del cuestionario, superando el valor “aceptable”. Se encontró una correlación estadísticamente significativa (p < .05) entre el número de años de experiencia como entrenador sénior y el 45.8% de las decisiones de programación; los entrenadores con más años de experiencia sénior empleaban con una frecuencia mayor las diferentes decisiones de programación. Como conclusión, este instrumento puede considerarse válido y fiable para conocer las decisiones de programación de los contenidos del entrenamiento en balonmano.Abstract: The aim of this study was to design and approve a survey to analyze decisions regarding the contents of a program for Handball training. The development and validity processes consisted of four phases: design of the instrument by a focus group, validation of the content by a panel consisting of 11 experts (Delphi technique), comprehension validation with 23 coaches, and a pilot study with 30 coaches to evaluate the internal consistency (Cronbach's alpha) and construct validity (link between programming decisions and years of experience as senior coaches). The validation by experts led to define an instrument with 52 questions with an adequate level of comprehension. Cronbach's alpha was higher than 0.95 in all questionnaire’s dimensions, exceeding the “acceptable” level. A statistically significant correlation (p < .05) was found between years of experience as senior coaches and 45.8% of the training program decisions; coaches with more years of senior experience relied on different programming decisions more often. In conclusion, this can be considered a valid and reliable instrument to deduce what decisions are adopted with regard to the contents of any Handball training program.

Leonardo da Vinci in the 16th century, used injection replica techniques to study internal surfaces of the cerebral ventricles. Developments in replicating media have made it possible for modern morphologists to examine injection replicas of lung and kidney with the scanning electron microscope (SEM). Deeply concave surfaces and interrelationships to tubular structures are difficult to examine with the SEM. Injection replicas convert concavities to convexities and tubes to rods, overcoming these difficulties.Batson's plastic was injected into the renal artery of a horse kidney. Latex was injected into the pulmonary artery and cementex in the trachea of a cat. Following polymerization the tissues were removed by digestion in concentrated HCl. Slices of dog kidney were aldehyde fixed by immersion. Rat lung was aldehyde fixed by perfusion via the trachea at 30 cm H2O. Pieces of tissue 10 x 10 x 2 mm were critical point dried using CO2. Selected areas of replicas and tissues were coated with silver and gold and examined with the SEM.

Purpose This pilot study explored the effectiveness of an early storybook reading (ESR) intervention for parents with babies with hearing loss (HL) for improving (a) parents' book selection skills, (b) parent–child eye contact, and (c) parent–child turn-taking. Advancing research into ESR, this study examined whether the benefits from an ESR intervention reported for babies without HL were also observed in babies with HL. Method Four mother–baby dyads participated in a multiple baseline single-case experimental design across behaviors. Treatment effects for parents' book selection skills, parent–child eye contact, and parent–child turn-taking were examined using visual analysis and Tau-U analysis. Results Statistically significant increases, with large to very large effect sizes, were observed for all 4 participants for parent–child eye contact and parent–child turn-taking. Limited improvements with ceiling effects were observed for parents' book selection skills. Conclusion The findings provide preliminary evidence for the effectiveness of an ESR intervention for babies with HL for promoting parent–child interactions through eye contact and turn-taking.
