One of the most widely used and studied instruments worldwide to assess the reasons for consuming alcohol is the Drinking Motives Questionnaire (DMQ) based on the Cox & Klinger (1988) model, of which different versions have been made and have shown different factorial structures. However, in Mexico the psychometric properties of the DMQ and its versions have not been studied. Objetive. Due to the need for an instrument to assess the reasons for alcohol consumption, this study set out to adapt and study some psychometric properties of the DMQ-R and its different versions in the Mexican adolescent population. Method. The longest version of the questionnaire (28 items) was administered to 464 adolescents between 13 and 18 years old (M = 16.20; SD = 1.24), in this sample n=179 were female (55.1%). Results. Five different versions of the test were fitted. The only model that obtained an adequate fit was that of the short version of 12 questions, which also showed adequate internal consistency indexes (α = .88 y ω = .94). Conclusion. The short version of the DMQ-R-12 is an instrument that has shown adequate construct validity and reliability to evaluate the reasons for alcohol consumption in Mexican adolescents.

Psychometric properties of the Levenson's Self-Report Psychopathy Scale (LSRP) are evaluated in incarcerated (n = 300) and non-incarcerated (n = 248) samples in the Mexican population. The models that have been reported in previous studies were tested by means of a confirmatory factor analysis (CFA). Brinkley's trifactorial model was the one presenting the best fit, whose indicators were similar to those reported in previous studies. Regarding reliability, a Cronbach's alpha =.766 and McDonald's omega =.761 was obtained for the total scale. The observed results provide theoretical and practical support on the dimensionality of the psychopathy construct. Implications for both research and assessment of psychopathy in correctional facilities and in the general population are discussed. [ABSTRACT FROM AUTHOR]

Procrastination has been defined as an irrational delay in behavior associated with multiple negative consequences, among which the incidence in mental health is prominent. Given the importance of detecting irrational procrastination, this research proposed to adapt and study some psychometric properties of the IPS (Irrational Procrastination Scale) in the Mexican population. The 9-item IPS scale was applied to 960 university students between 18 and 56 years old (M= 21.31, SD= 3.77), with a majority of women (n= 566, 59.0%). The final version of seven items obtained a Cronbach's alpha of 0.803. Through an exploratory factor analysis with half of the sample, it was observed that the scale is unifactorial, explaining 46.07% of the variance. This was corroborated with the other half and by confirmatory factor analysis. It is concluded that IPS is a short and reliable instrument to detect irrational procrastination which can be an effective screening tool for the Mexican population. [ABSTRACT FROM AUTHOR]

The decrease in the ability to enjoy can be considered a risk factor or marker of mental disorders. Therefore, it can be useful to have a scale to quantify gaudiebility in children and adolescents. The objective of the present work was to build and analyze the psychometric properties of the Gaudiebility Scale for Children and Adolescents (GSCA). 1,264 primary, secondary and high school students responded to GSCA, Rosenberg's self-esteem scale, Positive and Negative Affect schedule, Center of Epidemiological Studies of Depression scale. Through a confirmatory factor analysis using WLSMV (Weighted Least Square) estimation with a reparameterization with a value of d = .05 and forcing a non-orthogonal factor structure was observed to 5 factors model (Enjoyment in Company, Selfefficacy versus boredom, Sense of humor, Imagination and Interest) related, results (X2/df = 9.40; CFI = .931; TLI = .946) indicate that the modification indices did not present relevant values, so it would not be pertinent to propose any other alternative model. In addition, an appropriate internal reliability (Cronbach a = .794) was observed in the total scale and in the 5 subscales. Finally, an adequate evidence of validity was observed. It is concluded that GSCA seems appropriate to quantify gaudiebility levels in children and adolescents. [ABSTRACT FROM AUTHOR]

Una de las escalas más utilizadas para evaluar la ansiedad es el BAI (Beck Anxiety Inventory) que ha mostrado adecuadas propiedades psicométricas; sin embargo, no hay consenso sobre su estructura interna. Este trabajo tuvo como objetivo estudiar la estructura interna del BAI haciendo uso del Análisis Factorial Confirmatorio (AFC) por primera vez en México, así como la bondad de los ítems que la componen y su consistencia interna. Además, se presentan datos descriptivos de los niveles de ansiedad en población general de Michoacán (México). Se administró la escala BAI al mismo tiempo que se solicitaron datos sociodemográficos (sexo, edad, estado civil y escolaridad) a 1,245 personas adultas. Primero, se realizó un Análisis Factorial Exploratorio (AFE) con la mitad de la muestra; posteriormente, con la segunda mitad de la muestra y a través de un AFC, se pusieron a prueba los modelos factoriales obtenidos en estudios mexicanos previos, la solución unifactorial, así como el modelo obtenido en el AFE. Se observó una elevada consistencia interna de la escala total (α =.911); sin embargo, ningún modelo de los probados en el AFC resultó satisfactorio. Puede concluirse que el BAI, a pesar de mostrar una estructura interna inestable, es adecuado para evaluar la presencia de sintomatología de ansiedad en población general de Michoacán (México). Es importante señalar que hasta un 24.9% de la muestra presentó niveles de ansiedad moderada o severa. One of the most widely used scales to assess anxiety is the BAI (Beck Anxiety Inventory) that has shown adequate psychometric properties; however, there is no consensus on its internal structure. This work aimed to study the internal structure of the BAI using Confirmatory Factor Analysis (AFC) for the first time in Mexico, as well as the goodness of the items that make it up and its internal consistency. In addition, descriptive data of anxiety levels in the general population of Michoacán (Mexico) are presented. The BAI was administered and the sociodemographic data (sex, age, marital status, and education) were requested from 1,245 adults. First, an Exploratory Factor Analysis (EFA) was carried out with half the sample. Using the second half of the sample, the factorial models obtained in previous Mexican studies, the single factor solution and the model obtained in the AFE were tested through a CFA. A high internal consistency of the total scale was observed (α =.911); however, no model of those tested in the CFA was satisfactory. It can be concluded that the BAI, despite showing an unstable internal structure, can adequately assess the presence of anxiety symptoms in the general population of Michoacán (Mexico). It is important to note that up to 24.9% of the sample presented moderate or severe anxiety levels. [ABSTRACT FROM AUTHOR]

Los trastornos de ansiedad actualmente son los trastornos mentales más frecuentes, y suponen un importante problema de salud en México, por ello es importante disponer de instrumentos para su detección. En la presente investigación se estudiaron algunas propiedades psicométricas de la escala Generalized Anxiety Disorder Inventory (GADI) en población universitaria de M orelia (México). Aplicamos la escala GADI junto a escalas que evalúan la presencia de ansiedad, preocupación patológica, sintomatología depresiva y gaudibilidad a una muestra de universitarios. Se aplicó un análisis factorial confirmatorio. Nuestros resultados corroboran la estructura de 3 factores de la versión original y de otros estudios. Se observó una elevada consistencia interna de la escala total (α =.928) y también resultó adecuada para los 3 factores. Respecto a las evidencias de validez concurrente, las correlaciones entre la escala GADI y las otras escalas fueron las esperadas. También se observó una elevada fiabilidad test-retest en un tiempo de 4 semanas. Los datos empíricos indican que la escala GADI presenta una validez y fiabilidad satisfactorias para población universitaria. Asimismo, se ofrecen datos descriptivos en población universitaria de Morelia (México). Anxiety disorders are the most frequent mental disorders and they represent an important health problem in Mexico, so it is important to detect them with the use of valid assessment instruments. The goal of our study is to establish several psychometric properties of the GADI (Generalized Anxiety Disorder Inventory) in college students of Morelia (Mexico). The GADI and other scales were applied to assess the presence of anxiety, pathological worry, depressive symptomatology and gaudiebility in a sample of university students. A confirmatory factor analysis was applied. Our results corroborate the three factor structure of the original version and other studies. We observed a high internal consistency of the total scale (α =.928) and also was adequate for the 3 factors. Regarding the evidence of concurrent validity, the correlations between the GADI scale and the other scales were as expected. High test-retest reliability was also observed in a period of four weeks. the empirical data indicate that the GADI presents satisfactory validity and reliability for college population. Likewise, descriptive data are offered in the university population of Morelia (Mexico). [ABSTRACT FROM AUTHOR]
