Adaptación al español del Inventario Multidimensional de Fatiga al entorno laboral / Adaptation into Spanish of the Multidimensional Fatigue Inventory in Work Environment

La necesidad de evaluar la fatiga al entorno laboral es esencial para poder desarrollar programas de prevención e intervención. El principal objetivo de este trabajo fue adaptar del inglés al español el Inventario Multidimensional de Fatiga. Se analizaron la estructura interna y la fiabilidad, y se aportaron evidencias de validez convergente. La aplicación de la escala se realizó a una muestra multiocupacional compuesta por 414 empleados. También se utilizaron varios correlatos externos y dos escalas de contraste. Se aplicó el análisis factorial tanto exploratorio como confirmatorio. Los resultados indican que la versión española está conformada por 19 ítems y tres factores denominados Fatiga General, Fatiga Física y Concentración/Motivación. Los coeficientes de fiabilidad obtenidos fueron adecuados y, además, se obtuvieron evidencias de validez con cuatro correlatos externos y dos escalas de fatiga. La presente escala adaptada al español muestra unas propiedades psicométricas idóneas y puede resultar adecuada para identificar de manera apropiada la fatiga en entornos laborales. Futuras investigaciones podrían utilizarla como una herramienta de screening en combinación con otros instrumentos.

Evaluation of fatigue in work environment is crucial in order to draw up prevention and intervention programmes. The main objective of this study is to adapt the Multidimensional Fatigue Inventory from English into Spanish. I analysed the internal structure and reliability and evidence was found of convergent validity. The scale was applied to a multi-occupational simple made up of 414 employees. Various external correlates and two contrast scales were also used. An exploratory as well as a confirmatory factor analysis were undertaken. The findings indicate that the Spanish version which we have presented is made up of nineteen items and three factors, namely Gendoieral Fatigue, Physical Fatigue and Concentration/Motivation. The resulting reliability coefficients were adequate and, what's more, evidence of validity was found for four external correlates and two fatigue scales. The present scale, adapted into Spanish displays ideal psychometric properties and may prove ideal for adequately identifying fatigue in work environments. The scale could be used in future research as a screening tool in combination with other instruments.

Diseño de un instrumento psicométrico para el estudio de deseos y defensas con el enfoque del algoritmo David Liberman (ADL) / Psychometric instrument design for the study of wishes and defenses, using the Daivd Liberman Algorithm (DLA) approach

Presentamos el diseño de un nuevo instrumento psicométrico que integraría el arsenal de herramientas del Algoritmo David Liberman (ADL) para la investigación de los deseos y las defensas (y su estado) en los evaluados. El instrumento tiene un carácter mixto, ya que la primera parte está constituida por un cuestionario autoadministrable de 168 ítems, que el entrevistado deberá responder según los valores de una escala likert especialmente diseñada, y la otra, complementaria, consiste en dos consignas en las cuales se le solicita al evaluado que relate dos episodios, uno de la infancia y otro de la vida reciente.

Liberalismo / conservadorismo sexual: proposta de uma medida multi-fatorial / Sexual liberalism / conservatism: proposal of a multi-factorial measurement

Este estudo objetiva apresentar uma medida multi-fatorial de liberalismo / conservadorismo sexual. Partiu-se do Questionário de Atitudes Sexuais, sendo acrescentados novos itens. Para tanto, foram realizados dois estudos. No primeiro, os participantes responderam o Questionário de Atitudes Sexuais, dividido em duas sub-escalas (Self e Other), e questões demográficas. Os resultados das análises fatoriais exploratórias evidenciaram um fator geral de liberalismo / conservadorismo sexual. No segundo estudo os participantes responderam o Questionário de Liberalismo / Conservadorismo Sexual (QLCS), a Escala de Conservadorismo Moral, a Escala de Tradicionalismo Moral e questões demográficas. Mediante uma análise fatorial confirmatória, comprovou-se a estrutura multi-fatorial do QLCS, que revelou índices aceitáveis de bondade de ajuste. Os Alfas de Cronbach encontrados para os fatores de segunda ordem foram 0,88 (Self) e 0,90 (Other). Todos os fatores do liberalismo se correlacionaram entre si e com as escalas de conservadorismo e tradicionalismo moral, comprovando a validade convergente do instrumento psicométrico, que se mostrou adequado para utilização no contexto brasileiro.

This study aims at presenting a multi-factorial measurement of sexual liberalism/conservatism. New items were added to the Sexual Attitudes Questionnaire and two studies were developed. During the first study, the participants answered the Sexual Attitudes Questionnaire, divided in two sub-scales (Self and Other), and demographic questions. The results of the exploratory factor analysis showed a general factor of sexual liberalism/conservatism. In the second study, the participants answered the Sexual Liberalism/Conservatism Questionnaire (SLCQ), the Moral Conservatism Scale, the Moral Traditionalism Scale and demographic questions. By means of a confirmatory factorial analysis, the multi-factorial structure of the SLCQ was confirmed, revealing acceptable indexes of goodness-of-fit. The Cronbach's Alpha found to the second order factors were .88 (Self) and .90 (Other). All factors of liberalism correlated themselves with each other and with the conservatism and traditionalism scales, corroborating the convergent validity of the psychometric instrument, wich proved its adequacy for use in the Brazilian context.
