Background: A new instrument was designed to measure attitudes towards intellectual disability in the workplace. This tool provides the opportunity to identify underlying cognitive and emotional patterns that may influence people's interaction and performance in such environments. Objective: To construct, validate, and ensure the reliability of a scale measuring attitudes towards intellectual disability, establishing its suitability in labor inclusion programs. Method: A psychometric design was used that incorporated qualitative techniques, such as focus groups and cognitive interviews, in the instrument construction phase. The content validation of the items involved the participation of 15 experts in the field, which resulted in a reduced version with 10 items distributed in two dimensions: Perception and Social Distance. Subsequently, both the validity of the ...

The aim of this study was to assess the psychometric properties of the Comprehensive Quality of Life Scale, Objective Version. Content validity was obtained using Aiken’s V coefficient with the participation of 10 experts and inter-rater reliability was assessed with a sample of 45 participants from 15 families with presence of an intellectual disabled. The results showed insufficient validity in the criteria of clarity, consistency and relevance. The inter-observer reliability was moderate with an overall coefficient of .58. A new version of the scale was obtained for intellectual disabled persons, adapted to the sociocultural characteristics of Lima, Perú.

Se evaluaron las propiedades psicométricas de la Escala Integral de Calidad de Vida: Versión Objetiva. Se obtuvo evidencias de validez por contenido mediante el coeficiente V de Aiken con participación de 10 jueces expertos y análisis de fiabilidad inter-observador en una muestra de 45 personas pertenecientes a 15 familias con presencia de una persona con discapacidad intelectual. Los resultados muestran una insuficiente evidencia de validez de jueces en cuanto a los criterios de claridad, coherencia, relevancia y suficiencia presentados. La fiabilidad inter-observador reporta un coeficiente Krippendorff ’s Alpha total de .58, correspondiente a nivel moderado. Se obtuvo una nueva versión de la Escala Integral de Calidad de Vida: Versión Objetiva para personas con discapacidad intelectual adaptada a las características de la realidad sociocultural de Lima, Perú.

The job satisfaction evaluation allows us to know and explain several behavioral results of a worker such as his job performance. This study analyzes the internal structure of the brief version by Warr, Cook and Wall’s Job Satisfaction Scale (1979), which is designed to unidimensionaly measure the job satisfaction construct with items related to intrinsic and extrinsic satisfaction. The sample was composed by 88 professionals from a rehabilitation institution located in Metropolitan Lima, who were given the full version of the instrument (16 items), to examine the abbreviated version and derive a new one. We performed a confirmatory factor analysis (CFA) to evaluate the factorial structure through the modeling of structural equations. It was found that a latent dimension is valid for the comprehensive instrument, and a new version was obtained with different items, greater explained va...

Stress is a public health disease that is increasing rapidly in the population worldwide, so it is necessary to take measures for detection and evaluation, through short scales. The purpose of the study was to analyze the psychometric properties of the Perceived Stress Scale (PSS) in a sample made up of 752 people with an age range of 18 to 62 years (M = 30.18, DE = 10.175), of whom 44% (331) were women and 56% (421) men, from Lima, Peru. The results, by means of confirmatory factor analysis and the Rasch model, confirmed the global adjustment of a 12-item (PSS-12) version with the presence of two orthogonal factors independent of each other, and also demonstrated the metric equivalence according to gender and adequate internal consistency. These results allow us to recommend the use of the PSS-12 in the Peruvian population for the measurement of stress.

Objetivos: Obtener indicadores de confiabilidad y de validez de constructo del Índice Descriptivo de Trabajo (JDI) mediante el método de análisis factorial. Material y métodos: Estudio de tipo psicométrico. El JDI está compuesto por 72 ítems agrupados en cinco dimensiones: Trabajo en general, Sueldo, Compañeros, Supervisión y Promoción. Además, se cuenta con una escala adicional que mide la satisfacción laboral de manera general. Esta escala se denomina Trabajo en General (JIG) y suele aplicarse junto con el JDI. La muestra estuvo conformada por 166 trabajadores de tres instituciones públicas de salud de Lima. Se realizaron correlaciones inter-ítem, análisis factorial confirmatorio en cada una de las dimensiones y consistencia interna con el coeficiente omega. Resultados: Se encontró que las dimensiones del JDI funcionan adecuadamente, aunque fue necesario eliminar alguno...
