El objetivo del presente estudio fue probar la confiabilidad y validez de constructo de la version modificada del CFQ en poblacion mexicana. Previo a la evaluacion de las caracteristicas psicometricas, la escala fue traducida al espanol, usando el metodo de traduccion retraduccion, a partir del cual se hicieron modificaciones a algunos items, para hacerlos culturalmente adecuados y se agregaron tres nuevos items. Participaron un total de 1157 mujeres con hijos de 5 a 12 anos de edad. Se obtuvo una confiabilidad a traves del coeficiente alpha de Cronbach de .858. Se confirmo la validez de constructo, a traves del analisis factorial de componentes principales con rotacion varimax, del cual se obtuvieron ocho factores que explican 59.99% de varianza. Se obtuvo un KMO de .785 y una Chi-cuadrada de 6400.172, p

Adaptation of the BDI–II in Mexico. (Adaptación del IDB-II en México)

The number of Spanish-speaking individuals and immigrants in the United States has risen dramatically and is projected to continue to rise. The availability of appropriately translated and validated measurement instruments, such as the Beck Depression Inventory, is a priority for researchers and clinicians in the U.S. and Mexico, where the first edition of the BDI is still prominently used. The purpose of this study was to pilot a Mexican adaptation of the BDI-II and report initial psychometric characteristics. Two samples were used: students from across Mexico and community adults from Mexico City. Results indicated that the translation was easily understood by most individuals, had adequate internal consistency, and a three-factor structure (negative attitude, performance difficulties, and somatic elements) had the best fit. Implications for use with Mexican-origin Spanish speakers are discussed.

Desarrollo y validación psicométrica de la Escala de Privacidad en la Vivienda

The main objective of this research was to generate a reliable and valid scale that assessed dwelling privacy in Mexico City’s population. A scale was developed specifically for this purpose. The scale included 20 items with five options for answers (Never, few times, sometimes, frequently and always). The scale was applied to a sample of 200 Mexico City’s inhabitants in order to obtain its psychometrical validation. The distribution of the participants was as follow: age between 14 to 75; 110 women and 90 men: diverse occupations and school levels. A proper analysis took place in order to learn about the items discriminative power, reliability and valid factorial structure. The final scale was conformed by 11 items organized by three factors as follow: 1) Information Access Control, 2) Person Access Control and 3) Intimacy it explains 68% of variance and has a reliability of Cronbach Alpha =0.89. Afterwards a Confirmatory Factor Analysis was conducted to verify if the structure obtained from the Principal Component Analysis was correct, and a good fit was achieved (df=39, x2= 48.07, p=.151; CFI= .987; RMSEA= .032).

Preferencias alimentarias y su asociación con alimentos saludables y no saludables en niños preescolares

Childhood obesity is a serious public health problem in Mexico and worldwide. The study of food preferences in young children can help prevent selection of unhealthy food, which in recent years has increased. The goal of the study was to explore the food preferences of a sample of preschoolers and to determine whether they were able to differentiate between healthy and unhealthy food. We sampled 127 preschoolers between 3 and 6 years of age (M = 5.0, SD = .69). Participants were asked to classify 88 types of food into 11 categories. They were also asked to indicate the types of food that they like and that are healthy and unhealthy. Participants indicated that they preferred the sugars (candy, ice cream) and fruits (apples, melon) groups and disliked vegetables. They identified fruits and vegetables as healthy and sugars and fats as unhealthy food.

Escala de felicidad en la pareja: Desarrollo y validación

Human happiness is complex, and in interpersonal terms, particularly in a relationship, there are many elements involved (Argyle, 1987). But there is no scale to measure happiness in the couple, therefore, the objective was to develop and validate a scale of happiness in the couple, culturally appropriated and reliable. The research was conducted in two phases. In the first phase, a scale for happiness in the couple was developed and reliability and validity were obtained; in the second phase, we performed a second-order factor analysis. The results showed a valid and reliable scale that measures the evaluation of happiness in the couple as well as the elements needed for a couple to be happy.

La mémoire des citoyens sur les événements et les personnages du Mexique

L’etude porte sur la memoire collective qu’ont les citoyens mexicains de leur histoire, a travers les personnages et les evenements importants. L’objectif est de determiner les dimensions, qui composent la structure de cette memoire, selon laquelle est interprete le devenir historique. Pour cela, on a constitue un echantillon de 1 477 citoyens de quatre generations de la zone metropolitaine de la ville de Mexico. L’etude a ete realisee en 2009, avant l’annonce des festivites du bicentenaire de l’Independance. Les resultats revelent la presence de deux grands systemes de pensee, l’un statique et l’autre dynamique. Le premier ne montre pas de differences entre les generations, alors que le second accentue les differences existantes et promeut des attitudes distinctes.
