Additionally, no study examined whether spousal levels of optimism and pessimism affect an individual's biological markers of cardiovascular health.
However, the handful of studies focusing on cardiovascular biomarkers show inconsistent effects. El instrumento puede recomendarse para medir optimismo disposicional y pesimismo en investigación epidemiológica y en la práctica clínica.ĭescriptive survey study Factor structure Measurement invariance Optimism Pessimism.Studies have demonstrated the importance of optimism in predicting perceived general health. Conclusiones: El estudio confirma la estructura bidimensional del LOT-R y la invarianza en género y edad. Se proveen valores normativos para el LOT-R. Se encontraron bajos puntajes medios en personas desempleadas, personas con bajos ingresos, fumadores y personas con obesidad. Solamente se encontraron pequeñas diferencias de género en el puntaje total ( M = 16,4 para mujeres y M = 16,1 para hombres). Las pruebas de invarianza para género y edad confirmaron la invarianza métrica. Resultados: El Análisis Factorial Confirmatorio (CFA) sugiere dos factores (correlacionados): Optimismo y Pesimismo. Método: Para ello se entrevistó una muestra comunitaria aleatoriamente seleccionada de la población general alemana, con un rango de edad de 19-80 años ( N = 9.711). Los objetivos de este estudio fueron establecer las propiedades psicométricas del LOT-R, y probar la asociación entre optimismo y varios factores psicológicos, socio-demográficos y conductuales. We can recommend using this instrument for measuring dispositional optimism and pessimism in epidemiological research and clinical practice.Īntecedentes/Objetivo: La versión revisada del Life Orientation Test (LOT-R) se emplea a menudo para evaluar el optimismo disposicional. Conclusions: The study confirmed the bidimensional structure of the LOT-R and invariance across age and gender. Normative scores of the LOT-R are provided. Low optimism mean scores were observed for unemployed people, people with low income, smokers, and obese people. The correlation between the subscales Optimism and Pessimism was strong for young and well educated people. There were only small gender differences in the LOT-R total score ( M = 16.4 for females and M = 16.1 for males). Invariance tests across gender and age groups confirmed metric invariance. Results: The Confirmatory Factor Analysis (CFA) proved two (correlated) factors: Optimism and Pessimism. Method: A randomly selected German general population community sample with an age range of 18-80 years ( N = 9,711) was surveyed. The aims of this study were to test psychometric properties of the LOT-R, to provide normative scores, and to test the association between optimism and several psychological, sociodemographic, and behavioral factors.
Background/Objective: The Life Orientation Test-Revised (LOT-R) is often used to assess dispositional optimism.
