ABSTRACT
Resumen La cohesión vecinal podría ser un constructo tanto multidimensional como de un solo factor, según la población que se mida; sin embargo, su operacionalización se ha realizado en culturas individualistas o con economías de altos ingresos. Por lo tanto, los objetivos de este trabajo fueron conocer la estructura factorial de la cohesión vecinal en una población colectivista y comprobar su consistencia interna global y por factor. Se aplicó de manera individual una escala de auto-reporte tipo Likert con 48 reactivos a 513 habitantes de la Ciudad de México con edades entre 15 y 78 años, que residían en colonias de distintos niveles socioeconómicos. Un análisis factorial exploratorio arrojó una estructura organizada en tres factores que explican el 54% de la varianza (α = .91), lo cual se corroboró con un análisis factorial confirmatorio. Se concluye que, en la versión adaptada del Instrumento de Cohesión Vecinal, se valida el modelo de tres factores (sentido de comunidad, atracción al vecindario y relaciones vecinales), y se comprueba una consistencia interna global excelente y buena para sus factores. Se sugiere el uso y baremación de esta escala en México.
Abstract Neighborhood cohesion comprises three elements: Sense of community, neighboring, and attraction to neighborhood. This theoretical structure has not always been found in empirical research and it has only been tested in individualistic cultures or in high economy countries. Therefore, the purpose of this study was to obtain the factorial structure of neighborhood cohesion among a collectivist population. To achieve this, a total sample of 513 residents of Mexico City was obtained; participants lived in neighborhoods with different income levels and had ages from 15 to 78 years old. Participants individually answered a self-report neighborhood cohesion instrument with a Likert scale response format that ranged from one (totally disagree) to five (totally agree). The instrument was previously translated to Spanish from the English original version and then adapted to the intended population. The sample was divided into two randomized sub-samples in order to conduct separated analysis. Exploratory factor analysis was conducted with the first sub-sample (n = 240), and it displayed a three-factor structure of neighborhood cohesion that explained 54% of the total variance with high internal consistency (α = .91). Confirmatory factor analysis was conducted with the second sub-sample (n = 273); a three-factor model showed better fit indexes compared with a one factor model. Also, a modification search was conducted to obtain a model with better fit, resulting in the removal of some items. In conclusion, through the adapted version of the Neighborhood Cohesion Instrument the three-factor model is validated (sense of community, attraction to neighborhood and relations with neighbors) along with an excellent global internal consistency and good for each factor. The use of this scale in Mexico is recommended, as well as obtaining norms for this population.
ABSTRACT
Abstract The objective of the present study was to design, validate and obtain the reliability of the Maternal Self-efficacy Scale for the Prevention of Overweight. From an exploratory research where the role of mothers in childhood obesity was studied, 25 items were written, after an assessment by a panel of judges. The validation was carried out twice with different samples. The first one were 400 mothers (Mage = 33.1, SD = 6.8) of children aged 3-6 years (M = 5.0, SD = 0.6) and 18 items were obtained, divided into four factors: Food, Programming, Solutions, and Prohibition, with a Cronbach's alpha (α) between .62 - .88 and omega (ω) coefficients of .76 - .94. The second validation was with 369 participants, 97% were mothers (Medad = 32.4, DS = 7.9) of children aged 3-6 years (M = 5.0, DS = 0.6) and 3% were grandmothers. The scale was one-dimensional composed by 11 items, with α = .90, ω = .92, and explaining 52% of the variance that evaluates the perceived self-efficacy in the prevention of body weight excess. The proposed scale showed to be suitable and, therefore, its use will promote a greater understanding of childhood obesity.
Resumen El objetivo del presente estudio fue diseñar, validar y obtener la confiabilidad de la Escala de Autoeficacia Materna para la Prevención del Exceso de Peso. A partir de un estudio exploratorio que indagó el papel de las madres en la obesidad infantil, fueron redactados 25 ítems, mismos que fueron evaluados por un panel de jueces. La validación de este instrumento se realizó con diferentes muestras. En la primera participaron 400 madres (Medad = 33.1, DS = 6.8) de hijos de 3 a 6 años (M = 5.0, DS = 0.6), y se obtuvieron 18 ítems, distribuidos en cuatro factores: Alimentación, Programación, Soluciones y Prohibición, con alpha de Cronbach (α) entre .62 y .88, y coeficiente omega (ω) de .76 a .94. En la segunda validación participaron 369 madres (Medad = 32.4, DS = 7.9) de hijos de 3 a 6 años (M = 5.0, DS = 0.6) y el 3% de abuelas. La escala fue unidimensional, compuesta por 11 reactivos con α = .90, ω = .92 y varianza explicada del 52% de la autoeficacia percibida para la prevención del exceso de peso. La escala propuesta mostró ser apta y, por tanto, su uso promoverá un mayor entendimiento de la obesidad infantil.
ABSTRACT
Resumen La investigación sobre las relaciones de noviazgo en la adolescencia se ha visto frenada por diversos factores (Collins, 2003). La mayor parte de estudios sobre el tema se ha realizado con población juvenil y/o anglosajona; además, los cambios en su concepción han generado pocos los instrumentos que sirven para evaluar el fenómeno del noviazgo en adolescentes, y sus diferentes elementos. Por tal motivo, el propósito de este estudio fue analizar psicométricamente el Inventario Multidimensional de Noviazgo para Adolescentes (IMNOV-A). Participaron voluntariamente 503 adolescentes, con una edad entre 12 y 18 años (M = 15.71; D.E. = 1.78), que habían experimentado una relación de noviazgo, por lo menos una vez en la vida. A partir del método propuesto por Reyes Lagunes y García (2008), el inventario quedó constituido por la Subescala de Significado del Noviazgo (53.81% de la varianza total explicada, α = .886), y la Subescala de Motivos del Noviazgo (55.52% de la varianza total explicada, α = .938). Los resultados obtenidos se analizan desde la literatura sobre el desarrollo adolescente y los cambios en sus relaciones interpersonales; entonces, el significado y los motivos del noviazgo obedecen a los objetivos de esta etapa: obtener una identidad (Nahoul & González, 2013) y satisfacer necesidades socio-afectivas (Rice, 2001). Con esto, se plantea una medición más eficaz y eficiente sobre estas dimensiones del noviazgo, lo que da pie a continuar con esta línea de investigación e identificar los factores psicosociales que se relacionan con este fenómeno presente en la vida de esta población.
Abstract Research surrounding dating relationships in adolescents has been delayed because of several factors (Collins, 2003). Most of the research on this topic has been done in young and/or Anglo-Saxon populations; besides, changes in its perception have generated few useful instruments that can assess dating relationships and their inherent elements. Therefore, the purpose of this study was to evaluate the psychometric properties of the Dating Relationships Multidimensional Inventory for Adolescents (DATMI-A). The sample consisted of 503 adolescents that voluntarily agreed to participate, with ages between 12 and 18 (M= 15.71, SD = 1.78), who had been involved in a couple relationship at least once in their life. Following the method proposed by Reyes Lagunes and García (2008), the inventory ended being constituted by two sub-scales: The Dating Relationship Meaning Sub-scale (53.81% explained variance, α = .886), and the Dating Relationships Motives Sub-scale (55.52% explained variance, α = .938). These results are compared to relevant literature regarding adolescent development and changes in their interpersonal relationships. Therefore, both meaning and motives meet the goals for this stage of life: The acquisition of an identity (Nahoul & González, 2013) and the satisfaction of socio-affective needs (Rice, 2001). These findings suggest a more effective and efficient measurement regarding the aforementioned dimensions of dating relationships, which serves as a cornerstone for future research concerning the identification of psychosocial factors surrounding this phenomenon in everyday lives of this population.
ABSTRACT
Resumen: La fatiga es una sensación de cansancio físico con consecuencias adversas en la calidad de vida de las personas, por consiguiente, es importante contar con instrumentos confiables y válidos para medirla. Una de las escalas más utilizadas es la Escala de Impacto de Fatiga, sin embargo, hay versiones con una y tres dimensiones en diversas culturas. Por lo que el propósito de este trabajo fue traducir, adaptar de manera culturalmente relevante y comparar las estructuras de una y tres dimensiones de la Escala de Impacto de Fatiga, para identificar la más adecuada en población general de la Ciudad de México. Se trabajó con tres grupos diferentes de participantes; el primero para la traducción y adaptación conformado por siete jueces expertos en el idioma, el segundo para la validación psicométrica con 205 participantes de población general y, el tercero, para el análisis factorial confirmatorio con 406 habitantes de la Ciudad de México. Se probó la distribución, discriminación, confiabilidad y estructura de la escala, en un análisis exploratorio y confirmatorio, quedando una escala final de 10 reactivos con tres factores: física, mental y psicosocial que explican el 59% de varianza con buen ajuste (X2[21.7] =20,762, p = 0.522; CFI = 1; RMSEA = 0), con una confiabilidad α=0.93.
Abstract: Fatigue is a sensation of physical weariness with adverse consequences on the quality of life of people, therefore, it is important to have reliable and valid instruments to measure it. One of the most widely used is the Fatigue Impact Scale, however, there are one-and three-dimensional versions in several cultures. Therefore, the aim of this work was to translate, culturally relevant and compare the one and three-dimensional structures of the Fatigue Impact Scale to identify the most appropriate in the general population of Mexico City, with three different groups of participants. The first one for translation and adaptation made up with seven expert judges in the language; the second for psychometric validation with 205 participants from the general population, and the third, for confirmatory factor analysis with 406 inhabitants of Mexico City. The distribution, discrimination, reliability and structure of the scale were tested in an exploratory and confirmatory analysis, with a final scale of 10 items with three factors: physical, mental and psychosocial explaining the 59% variance with goodness of fit (X2[21.7] = 20.762, p = 0.522; CFI = 1; RMSEA = 0), with reliability α = 0.93.
