CAPI Versus PAPI and The Production of Some Non-Sampling Errors
2009
The study aims at assessing the differential effects of face-to-face paper and computer assisted interviewing in terms of efficacy, efficiency and the production of non-sampling errors. The research ground is constituted by the analysis of the customer satisfaction of a large-scale retail trade group owning many shops in Sicily. The reaction of respondents to paper versus electronic questionnaires is investigated by means of an experimental design in terms of non sampling error amounts.

Discordance between two national health statistics sources (EMH and EESCRI, 1990–2009). Analysis of psychiatric morbidity
2013
Abstract Introduction Two statistical sources provide data on hospital stays and discharges for all Spanish hospitals: Hospital Morbidity Survey (acronym in Spanish: EMH) and Statistics of Health Establishments providing Inpatient Care (acronym in Spanish: EESCRI). Our aim is to contrast these two statistical sources to define their accuracy and relevance in psychiatric epidemiology studies. Material and methodology The analysis is based on two aspects: (1) Compare the number of psychiatric stays and hospital discharges from 1990 to 2009. (2) Analyse and compare how the average stay is provided. Results The differences between the two statistical sources are significant and increase over ti…

VALIDACIÓN DE UNA ESCALA PARA EL ANÁLISIS DE LAS PERCEPCIONES DE LOS RESIDENTES SOBRE EL IMPACTO SOCIAL DE UN CENTRO DEPORTIVO
2019
Resumen La finalidad de este estudio es validar una escala para el análisis de las percepciones de los residentes sobre el impacto social de un centro deportivo. Se recogió una muestra de 406 residentes del municipio de Moncada (Valencia), con un error de muestreo de ±4,82, que contestaron a una encuesta de 31 ítems que recogían posibles impactos sociales derivados de la presencia del centro deportivo en la localidad. La aplicación de análisis factorial exploratorio y confirmatorio redujo la escala a 28 indicadores distribuidos en siete dimensiones de impacto: impacto sociocultural, impacto socioeconómico, impacto en la imagen y la promoción del municipio, impacto en el desarrollo urbano y …

22. Administering Face-To-Face Structured Questionnaires In Tourism Research
2018
Non-sampling errors occur in all social sciences, tourism included. Apart from coverage and non-response, tourism research suffers from noteworthy measurement errors. The limitation and control of non-sampling errors plays a key role to prevent serious biases in research outputs. The entire survey design process could be based on the control and reduction of non-sampling errors. From this point of view, face-to-face interviewing represents an effective response to some common threats to data quality, particularly errors attributable to respondents and non-response.
L’indagine sulla mobilità turistica: strumenti di rilevazione
2010
This paper discusses the features and the structure of the interview forms used within the sample research on tourist mobility carried out in Sicily and Sardinia in years 2009 and 2010. The focus of the paper is on the strategies adopted by the research team in order to control non sampling errors. The limitations of the instruments respect to the secondary purposes of the research will be discussed as well.
