Exploring relations among mindfulness facets and various meditation practices: Do they work in different ways?
2017
Several meditation practices are associated with mindfulness-based interventions but little is known about their specific effects on the development of different mindfulness facets. This study aimed to assess the relations among different practice variables, types of meditation, and mindfulness facets. The final sample was composed of 185 participants who completed an on-line survey, including information on the frequency and duration of each meditation practice, lifetime practice, and the Five-Facet Mindfulness Questionnaire. A Multiple Indicators Multiple Causes structural model was specified, estimated, and tested. Results showed that the Model's overall fit was adequate: chi(2) (1045) =…
Social Environmental Antecedents of Athletes’ Emotions
2021
The coach-created motivational climate influences variations in athletes’ motivation and emotional experiences. The present study aimed to examine social environmental antecedents of athletes’ emotions. Participants (N = 262, 52% female, M age = 22.75 ± 6.92) completed questionnaires assessing perceptions of coach-created motivational climates, goal orientations, motivation regulations, and emotions. The mediation effects of goal orientations (i.e., task/ego) and motivation regulations (i.e., autonomous/controlled) on the relationship between motivational climate (i.e., empowering/disempowering) and emotions (i.e., happiness, excitement, anxiety, dejection, and anger) were examined. Structu…
How Work Characteristics Are Related to European Workers’ Psychological Well-Being. A Comparison of Two Age Groups
2018
This study aimed to analyze the mechanisms through which work characteristics are related to psychological well-being, exploring the mediational role of work meaningfulness and job satisfaction, and investigating differences in the patterns of relationships between two age groups. The sample was composed of 36,896 workers from the 5th European Working Conditions Survey. Structural equation modeling analyses and multiple group analyses were performed. The results revealed a parallel mediational model, in which work meaningfulness and general job satisfaction mediate the relationships between work characteristics and well-being. Additionally, job satisfaction partially mediates the relationsh…
Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Spanish women
2014
Contains fulltext : 124145.pdf (Publisher’s version ) (Closed access) The Dutch Eating Behavior Questionnaire (DEBQ) was developed to measure eating styles that may contribute to or attenuate the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The main goal of this study is to evaluate the internal structure of the Spanish version of the DEBQ using updated psychometric techniques in a sample of women. A sample of 647 Spanish females answered the questionnaire. Both exploratory structural equation modeling and confirmatory factor analysis were used to evaluate the factor structure of the DEBQ. Reliabilities were estimated with Cron…
An integrated model of condom use in Sub-Saharan African youth: A meta-analysis.
2017
Objective: We tested an integrated social–cognitive model derived from multiple theories of the determinants of young people's condom use in Sub-Saharan Africa. The model comprised seven social–cognitive antecedents of condom use: Attitudes, norms, control, risk perceptions, barriers, intentions, and previous condom use. Method: We conducted a systematic search of studies including effects between at least one model construct and intended or actual condom use in young people from sub-Saharan African countries. Fifty-five studies comprising 72 independent data sets were included and subjected to random-effects meta-analysis. Demographic and methodological variables were coded as moderators. …
Predicting fruit and vegetable consumption in long-haul heavy goods vehicle drivers: Application of a multi-theory, dual-phase model and the contribu…
2017
Fruit and vegetable intake is insufficient in industrialized nations and long-haul heavy goods vehicle (HGV) drivers are considered a particularly at-risk group. The aim of the current study was to test the effectiveness of a multi-theory, dual-phase model to predict fruit and vegetable consumption in Australian long-haul HGV drivers. A secondary aim was to examine the effect of past fruit and vegetable consumption on model paths. A prospective design with two waves of data collection spaced one week apart was adopted. Long-haul HGV drivers (N = 212) completed an initial survey containing theory-based measures of motivation (autonomous motivation, intention), social cognition (attitudes, su…
Stress-related psychosocial factors at work, fatigue, and risky driving behavior in bus rapid transport (BRT) drivers
2016
Abstract Introduction There is consistent scientific evidence that professional drivers constitute an occupational group that is highly exposed to work related stressors. Furthermore, several recent studies associate work stress and fatigue with unsafe and counterproductive work behaviors. This study examines the association between stress-related work conditions of Bus Rapid Transport (BRT) drivers and risky driving behaviors; and examines whether fatigue is a mechanism that mediates the association between the two. Method A sample of 524 male Bus Rapid Transit (BRT) operators were drawn from four transport companies in Bogota, Colombia. The participants answered a survey which included an…
Comparison of prognostic models in patients with advanced Hodgkin disease
2001
Several prognostic systems have been elaborated for patients with Hodgkin disease (HD) over the last 12 years, but early identification of a reasonably large group of both low and high risk, advanced stage patients remains unsatisfactory.Seven well known models were applied to 516 patients with advanced HD, with 315 patients used for the study sample and 201 patients used for the test sample. Individual performances as well as joint performances were analyzed univariately and multivariately in relation to overall survival, recurrence free survival, and time to treatment failure by means of a proportional hazards model.None of the models identified a group containing10% of patients from the …
Idendity development, coping, and adjustment in emerging adults with a chronic illness: the sample case of type 1 diabetes
2008
Abstract Purpose The present study focused on identity development in emerging adults (aged 18–30 years) with type 1 diabetes. The three study aims were to examine the following: (1) whether identity development was affected by having diabetes, as compared with development in a nondiabetic sample; (2) how identity development was related to depressive symptoms, coping with diabetes, and diabetes-related problems in the diabetic sample; and (3) whether the pathways from identity development to problems with diabetes and depressive symptoms were mediated through coping strategies in the diabetic sample. Methods A total of 194 emerging adults with type 1 diabetes and 344 nondiabetic emerging a…

2021
This study analyses the cross-sectional effect of sources of stress during the peak of COVID-19 pandemic on nurses´ psychological distress, focusing on the mediating role of coping strategies, both problem focused and emotion focused and resilience.Cross-sectional and quantitative analyses.Structural equation modelling was performed using survey data obtained during the period between 1 April-25 May 2020 in a sample of 421 nurses from 39 Spanish provinces.Results confirmed that: (a) All the stressors have a significant, direct, and negative relationship with nurses´ psychological distress; (b) Emotion-focused strategies is negatively related to nurses´ psychological distress directly and in…
