چکیده

La confiabilidad es entendida como una propiedad métrica de las puntuaciones de un instrumento de medida. Recientemente se viene utilizando el coeficiente omega (ω) para la estimación de la confiabilidad. No obstante, la medición nunca es exacta por la influencia del error aleatorio, por esa razón es necesario calcular y reportar el intervalo de confianza (IC) que permite encontrar en valor verdadero en un rango de medida. En ese contexto, el artículo plantea una forma de estimar el IC mediante el método de bootstrap para facilitar este procedimiento se brindan códigos de R (un software de acceso libre) para que puedan realizarse los cálculos de una forma amigable. Se espera que el artículo sirva de ayuda a los investigadores de ámbito de salud.

Confidence intervals for population reliability coefficients: Evaluation of methods, recommendations, and software for composite measures.

A composite score is the sum of a set of components. For example, a total test score can be defined as the sum of the individual items. The reliability of composite scores is of interest in a wide variety of contexts due to their widespread use and applicability to many disciplines. The psychometric literature has devoted considerable time to discussing how to best estimate the population relia...

Confidence Intervals for Reliability 1 Running head: CONFIDENCE INTERVALS FOR RELIABILITY COEFFICIENTS Estimation of and Confidence Interval Formation for Reliability Coefficients of Homogeneous Measurement Instruments

The reliability of a composite score is a fundamental and important topic in psychology and related disciplines. The most commonly used reliability estimate of a composite score is coefficient alpha. However, under regularity conditions, the population value of coefficient alpha is only a lower bound on the population reliability, unless the items are essentially tau-equivalent, an assumption t...

Robust Coefficients Alpha and Omega and Confidence Intervals With Outlying Observations and Missing Data: Methods and Software

Cronbach’s coefficient alpha is a widely used reliability measure in social, behavioral, and education sciences. It is reported in nearly every study that involves measuring a construct through multiple items. With non-tau-equivalent items, McDonald’s omega has been used as a popular alternative to alpha in the literature. Traditional estimation methods for alpha and omega often implicitly assu...
