Resultados: El modelo mostró ajuste adecuado: c2(362) = 438.59 (p = .01), CFI = .98…
Continuous Glucose Monitoring in Type 1 Diabetes
2016
Background: Continuous glucose monitoring (CGM) patient systems have been shown to improve diabetes self-treatment when used consistently. The meaningful integration of this technology into everyday life, however, can vary greatly among CGM users and not all people with diabetes use CGM to its full potential. To address this issue, the study pursued 2 aims: first, to identify patient characteristics that underlie the acceptance of CGM in people with type 1 diabetes and, second, to examine the effects of different levels of experience with CGM use. Methods: Guided by a model based on the technology acceptance model (TAM), structural equation modeling (SEM) was employed to model the patient c…
Predicting determinants of satisfaction with the life in a sample of elderly students through(a) structural equation model
2015
The goal of this work is to examine the benefits of the Universities of Third Age in Portugal territory on the life of its senior students. It intends to verify if there could be any positive effect on the quality of life of these students, on their vital satisfaction and on their isolation and loneliness. Therefore, it seeks to determine the existence of depressive and anxiety symptoms in subjects. What if the activities offered by the Universities of Third Age promote the decrease of depressive and anxiety symptom. For this study, was collected a sample throughout the Portuguese territory, covering various Universities of the Third Age. The sample was composed only by elderly people who a…
Disability, physical activity, and muscle strength in older women: The women's health and aging study
1999
Abstract Objective: To study associations of motor disability, physical activity, and muscle strength in older women, in particular to investigate whether model of spiraling decrease is expressed in the data. Design: Cross-sectional analysis using data from the base-line measurements of The Women's Health and Aging Study (WHAS). Setting: Participants' homes. Participants: A total of 1,002 disabled women aged 65 years and older living in the community. Outcome Measures: Motor disability was measured by the number of self-reported difficulties in grasping, lifting 101b, walking across a small room, walking 14 mile, climbing 10 steps, and doing heavy housework. Level of physical activity was d…
Influencia del clima motivacional en clase sobre el compromiso escolar de los adolescentes y su logro académico
2017
The scientific literature provides empirical evidence on the relationship between school engagement and numerous important variables of the adolescents’ educational context. The school engagement has been related, among other important constructs, with burnout of both teachers and students, school performance, satisfaction with the school, behavioral disruption, goal orientation and motivational climate in the classroom. Because of it, the aim of this study was to analyze the relationship between perceived motivational class climate and students’ academic achievement, with school engagement acting as a mediator. A sample of 2028 teenagers completed various instruments to measure the percept…
Influence of the motivational climate in physical education on the intention to practice physical activity or sport
2001
This study is based on the achievement goal theory and intended to verify the effects of the motivational climate of the physical education (PE) on students' motivation, interest, and intention to practice physical activity or sport. In order to meet these objectives, 975 participants, from 13 to 18 years of age, completed the following instruments: PECCS, TEOSQ, IMI, Satisfaction Scale, and the Intention to Practice Physical Activity or Sport. The data were analyzed by means of Structural Equation Modeling (SEM). The results confirmed that the mastery dimension of motivational climate has an influence, directly or indirectly, on task orientation, the three dimensions of intrinsic motivatio…
Motivational climate, goal orientation, perceived sport ability, and enjoyment within Finnish junior ice hockey players
2015
The aim of this study was to investigate the relations among situational motivational climate, dispositional approach and avoidance achievement goals, perceived sport ability, and enjoyment in Finnish male junior ice hockey players. The sample comprised 265 junior B-level male players with a mean age of 17.03 years (SD = 0.63). Players filled questionnaires tapping their perceptions of coach motivational climate, achievement goals, perceived sport ability, and enjoyment. For the statistical analysis, players were divided into high and low perceived sport ability groups. Multigroup structural equation modeling (SEM) revealed an indirect path from task-involving motivational climate via task-…
Validez factorial del “cuestionario para la evaluación del síndrome de quemarse por el Trabajo” (CESQT) en una muestra de médicos mexicanos
2010
El objetivo del este estudio fue evaluar la validez factorial y la consistencia interna del “Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo” (CESQT). Se hipotetizó un modelo de cuatro factores, similar al del oringinal. La muestra fueron estuvo formada por 1110 médicos del Instituto Mexicano del Seguro Social. El instrumento está formado por 20 items distribuidos en 4 subescalas: Ilusión por el trabajo (5 items), Desgaste psíquico (4 items), Indolencia (6 items), y Culpa (5 items). El modelo fue evaluado con LISREL 8. Según diferentes índices de ajuste global el modelo presentó un ajuste adecuado: Chi2(164) = 225.06 (p < 0.001), GFI = 0.83, RMSEA = 0.061, NNFI = …

The reasoned action approach applied to health behavior: Role of past behavior and tests of some key moderators using meta-analytic structural equati…
2018
Abstract Rationale The reasoned action approach (RAA) is a social cognitive model that outlines the determinants of intentional behavior. Primary and meta-analytic studies support RAA predictions for multiple health behaviors. However, including past behavior as a predictor in the RAA may attenuate model effects. Direct effects of past behavior on behavior may reflect non-conscious processes whereas indirect effects of past behavior through social cognitive variables may represent reasoned processes. Objective The present study extended a previous meta-analysis of the RAA by including effects of past behavior. The analysis also tested effects of candidate moderators of model predictions: be…
