Background: Insomnia can harm daily functioning and is strongly associated with depression and anxiety symptoms, especially in women. El Salvador has no scales with adequate psychometric properties for their measurement. In this context, the Athens Insomnia Scale (AIS) is a viable option to measure this symptomatology, given its short length of time, solid theoretical foundation, and relevance in other countries. Objective: To analyze the psychometric properties of AIS in the Salvadoran population, in its complete (AIS-8) and abbreviated (AIS-5) versions. Method: The study consisted of 1479 Salvadoran adults from the 14 departments of the country (mean age = 33.3 years, SD = 11.7) who were screened through a non-probability sampling design. Evidence of reliability, validity based on internal structure, and convergent validity were examined. Results: Both scales showed adequate internal c...

Liu (1996) discute una clase de distribuciones robustas a las que apela como normal/independiente, y que contiene un grupo de distribuciones de colas pesadas. En este artículo desarrollamos una versión asimétrica de tales distribuciones en un escenario multivariado, a las que llamaremos distruciones normales asimétricas independientes multivariadas. Para tales distribuciones derivamos algunas propiedades. La principal virtud de los miembros de esta familia es que son fáciles de simular y se prestan a un algoritmo de tipo EM para realizar estimaciones de máxima verosimilitud de sus parámetros. Para dos modelos multivariados de interés práctico se discute el algoritmo EM con énfasis en las distribuciones t-asimétrica, slash asimétrica y normal asimétrica contaminada. Los resultados obtenidos a partir de simulaciones y de dos conjuntos de datos reales son reportados.

The effects of concentration and temperature on the thermo-physical properties of apple juice were studied, in which density and viscosity were measured at different temperature and concentration conditions, varying from 20°C to 80°C and from 12 to 70° Brix, respectively. Density was determined by the pycnometer method and viscosity by Hooke's falling sphere method, based on Stokes' law. The density results were correlated several times, arriving, by the least squares method, at a multiple linear regression model, of three terms; while the viscosity results proved to be more difficult to correlate, which, by the least squares method, arrived at a multiple linear regression model, of six terms. The experimental mathematical models can be used to obtain the density and viscosity data within the temperature and concentration conditions indicated in the study. Key words: density –...

The aim of this research was to review the psychometric properties of the Frost Multidimensional Perfectionism Scale(FMPS) in a non-clinical sample of 1,242 Mexican adults. The reliability and validity of the scale were assessed usingfactorial analyses, and Cronbach’s alpha (α) and McDonald’s omega (ω) indices were analyzed. The overall reliabilityof the scale was excellent (α = .928, ω = .928), with specific dimensions ranging from acceptable to excellent (concernover mistakes: α = .899, ω = .903; organization: α = .892, ω = .896). Exploratory factor analysis confirmed theadequacy of the data (KMO = .940, p < .001), with the final model fitting with five factors explaining 59.390% of thevariance. Confirmatory factor analysis yielded an RMSEA of .074, CMIN/DF of 7.882, GFI of .849, and CFI of .871,indicating acceptable but not excellent fit. These results suggest that the ...

This study examines the psychometric properties of the Matson Evaluation of Social Skills with Youngsters (Matson, Rotatori & Helsel, 1983), which assesses specific social skills involved in adaptive and non-adaptive behaviors. The factor structure and internal consistency were studied in a sample of children from Cordoba (n = 578) of 7 to 13 years old (M = 9.48, SD = 1.47) of both sexes (52.77% males). An exploratory study of data and variables was conducted; then the factor structure was studied. Results suggest that the structure of five factors was the simplest and theoretically most consistent: Aggressiveness/Antisocial Behavior, Appropriate Social Skills, Friendship, Overconfidence/Jealousy/Pride and Loneliness/ Social Anxiety. The internal consistent coefficients were good or acceptable in most dimensions. Gender differences observed in the dimensions and total score provide e...
