Measured and Perceived Physical Fitness, Intention, and Self-Reported Physical Activity in Adolescence
2011
Objective: The aim of this study was to investigate the associations among measured physical fitness, perceived fitness, intention towards future physical activity and self-reported physical activity through junior high school years. Methods: Study participants included 122 Finnish students who were 13 years old during Grade 7. The sample was comprised of 80 girls and 42 boys from 3 junior high schools (Grades 7-9). During the autumn semester of Grade 7, students completed fitness tests and a questionnaire analyzing self-perception of their physical fitness. The questionnaire delivered at Grade 8 included intention towards future physical activity. At Grade 9 students’ self-reported physica…
Does Sedentary Behavior Predict Academic Performance in Adolescents or the Other Way Round? A Longitudinal Path Analysis.
2016
This study examined whether adolescents’ time spent on sedentary behaviors (academic, technological-based and social-based activities) was a better predictor of academic performance than the reverse. A cohort of 755 adolescents participated in a three-year period study. Structural Equation Modeling techniques were used to test plausible causal hypotheses. Four competing models were analyzed to determine which model best fitted the data. The Best Model was separately tested by gender. The Best Model showed that academic performance was a better predictor of sedentary behaviors than the other way round. It also indicated that students who obtained excellent academic results were more likely t…
Specifications of model development
2016
Chapter 4 goes into detail with the specifications of the model and model validation. Why Partial Least Squares (PLS), a structural equation modelling approach, is chosen as the method for model testing is explained in section 4.1, while 4.2 describes the survey conducted to collect data for model testing. Section 4.3 goes into detail with the PLS approach, its theoretical background and its application to the research question, before section 4.4 outlines the necessary operationalisation of the constructs introduced in chapter 3.
Evidence of validity and measurement invariance by gender of the Vaccination Attitudes Examination (VAX) scale in Colombian university students
2022
Background: Having a valid tool to assess attitudes toward vaccination and identify the concerns that drive vaccine refusal can facilitate population studies and help guide public health interventions. The objective of this study has been to adapt the Vaccination Attitudes Examination (VAX) scale in Colombian university students and to study its psychometric properties in a non-probabilistic sample of 1074 Colombian university students. Methods: A confirmatory factor analysis was used to study the factorial structure. A structural equation model was tested to study concurrent validity and to check whether the factors predicted having received the coronavirus vaccine. Gender-based measuremen…
Using change trajectories to study the impacts of multi-annual habitat loss on fledgling production in an old forest specialist bird
2017
The loss and subdivision of habitat into smaller and more spatially isolated units due to human actions has been shown to adversely affect species worldwide. We examined how changes in old forest cover during eight years were associated with the cumulative number of fledged offspring at the end of study period in Eurasian treecreepers (Certhia familiaris) in Central Finland. We were specifically interested in whether the initial level of old forest cover moderated this relation. We applied a flexible and powerful approach, latent growth curve modelling in a structural equation modeling (SEM) framework, to create trajectories describing changes in old forest cover through time, and studied h…
What's on TV? The Impact of Brand Image and Celebrity Credibility on Television Consumption from an Ingredient Branding Perspective
2013
Today's multichannel, multimedia marketing environment presents a new layer of challenges. New demands from potential television viewers translate directly into the need of the creation and development of effective marketing strategies for the television (TV) market. This study proposes and validates a research model that analyzes an individual's TV show consumption by testing the impact of brand image and celebrity credibility. Based on the theoretical discussion, hypotheses were derived and tested with structural equation modeling on a basis of 306 consumers. Generally, the article provides evidence that brand image is the driving force in the explanation of a viewer's motivation to consu…
Examining the Performance of Brand-Extended Thematic-Content : The Divergent Impact of Avid- and Skim-Reader Groups
2017
Today, the reading online content is a daily habit for many users. In an online environment, users encounter brands, who hope to attract visitors to their online spheres of influence through brand-extended thematic-content. The purpose of this study is to investigate this phenomenon and assess its impact on both the readers of the content and the brands. To do this, we use structural equation modeling to analyze data from two groups, skim readers and avid readers, who vary in terms of the behaviors they invest in the reading of brand-extended thematic-content. The findings reveal that brand-extended thematic-content affects divergently on the brand attitude formation of these two groups. Sp…
Predicting change in middle school students’ leisure‐time physical activity participation: A prospective test of the trans‐contextual model
2020
We applied the trans-contextual model (TCM) to examine the effects of middle school students’ perceived autonomy support from their physical education (PE) teachers on autonomous motivation toward PE in school and, critically, autonomous motivation toward, and actual participation in, leisure-time physical activity (PA). The research adopted a three-wave prospective design enabling the modeling of change in the TCM constructs over time. Middle school students (N = 248) aged from 12 to 16 years reported their perceived autonomy support, autonomous motivation in PE, autonomous motivation toward leisure-time PA, attitudes, subjective norms, perceived behavioral control (PBC), intentions for PA…
Exploring working conditions as determinants of job satisfaction: an empirical test among Catalonia service workers
2011
Job satisfaction is particularly important in the service industries since it involves direct contact with customers and thus has a direct influence on company performance. This paper analyses the impact of 10 working conditions on job satisfaction by means of structural equation modeling in a representative stratified random sample of 1553 service sector employees in Catalonia, Spain. Significant effects in social aspects (recognition of a job well done and social support) were found, followed by psychological loads (emotional demands and job insecurity) and by task contents (development and meaning, and predictability). These variables explained 50% of the variance in job satisfaction.
