A meta-analysis of the health action process approach.
2019
Objective The health action process approach (HAPA) is a social-cognitive model specifying motivational and volitional determinants of health behavior. A meta-analysis of studies applying the HAPA in health behavior contexts was conducted to estimate the size and variability of correlations among model constructs, test model predictions, and test effects of past behavior and moderators (behavior type, sample type, measurement lag, study quality) on model relations. Method A literature search identified 95 studies meeting inclusion criteria with 108 independent samples. Averaged corrected correlations among HAPA constructs and multivariate tests of model predictions were computed using conve…
Method effects associated with negatively and positively worded items on the 12-item General Health Questionnaire (GHQ-12): results from a cross-sect…
2019
This study focused on the examination of the latent structure underlying the responses to the GHQ-12, considering the role of method effects associated with both, PW and NW items, and using two alternative parameterisations of the CFA measurement models. What should first be noted is that the studies that have included method effects in the measurement model of the GHQ-12 have been more the exception than the rule in previous research into the factor structure of this questionnaire. According to the results of the present study, we conclude that the GHQ-12 factor structure is best characterised by introducing latent method factors that capture both the method effects associated with NW and …
Psychometric Properties of the Diener Satisfaction With Life Scale With Five Response Options Applied to the Colombian Population
2022
Introduction: The Satisfaction with Life Scale (SWLS), developed by Diener, Emmons, Larsen, and Griffin in 1985, comprises five items with seven response options in terms of agreement–disagreement. Recently, there has been a suggestion to reduce the response options of the SWLS to optimize its applicability in different cultural contexts.Objective: The study aims to assess the psychometric properties of the SWLS with five response options in the Colombian population. Specifically, we studied the dimensionality, invariance by gender and age (among a group of adolescents and emerging adults under 25 years and a group of adults of intermediate age and established adulthood under 59 years), con…
Confirming the mechanisms behind cognitive-behavioural therapy effectiveness in chronic pain using structural equation modeling in a sample of patien…
2016
Objective To evaluate whether therapeutic mechanisms assumed to explain the effect of cognitive behavioural therapy (CBT) concerning temporomandibular symptoms are confirmed by structural equation modelling. Method Patients were randomly assigned to either an experimental group receiving CBT (N = 41) or a standard therapy control group (N = 31). Subjects were assessed before and after intervention using mediator variables hypothesized according to the CBT model, as well as outcome variables and other socio-demographic and clinical measures. Results The results confirm that the effect of treatment on pain intensity was partially mediated by distress, catastrophizing, perceived control, distr…
Does gender really matter? A structural equation model to explain risky and positive cycling behaviors
2018
Abstract Introduction While the use of bicycles as mean of transport is growing worldwide, the increasing rates of traffic crashes involving cyclists have turned into a relevant scientific, public health, and road safety concern. According to several studies, and despite the fact that some countries are taking part in preventive actions, the data indicate that the problem of cycling injuries implies high costs for the community welfare, for the economy, and for healthcare systems, thus proving a clear need for solutions. In this regard, and considering the available empirical evidence, risky and positive riding behaviors have gained significant weight in terms of explaining, intervening in,…
A confirmatory factor analytic validation of the Tinnitus Handicap Inventory
2015
Abstract Objective Because the postulated three-factor structure of the internationally widely used Tinnitus Handicap Inventory (THI) has not been confirmed yet by a confirmatory factor analytic approach this was the central aim of the current study. Methods From a clinical setting, N = 373 patients with chronic tinnitus completed the THI and further questionnaires assessing tinnitus-related and psychological variables. In order to analyze the psychometric properties of the THI, confirmatory factor analysis (CFA) and correlational analyses were conducted. Results CFA provided a statistically significant support for a better fit of the data to the hypothesized three-factor structure ( RMSEA…
Aligning personal and collective interests in emerging adults during the COVID-19 emergency in Italy
2021
This study investigated the relations of emerging adults' personal (civic competence and interdependent self-construal) and community-based (sense of community and civic engagement) resources as predictors of appraisal of COVID-19 Public Health Emergency Management (PHEM) and attitudes toward preventing contagion in Italy. Participants were 2873 Italian emerging adults (71% females) aged 19-30 years (M = 22.67, SD = 2.82). Structural equation modeling revealed both direct and indirect positive associations among study variables. Civic competence and interdependent self-construal were related to sense of community and civic engagement behavior which, in turn, predicted appraisal of PHEM. App…
Medication adherence in schizophrenia: The role of insight, therapeutic alliance and perceived trauma associated with psychiatric care
2017
Medication non adherence in schizophrenia is a major cause of relapse and hospitalization and remains for clinicians an important challenge. This study investigates the associations between insight, therapeutic alliance, perceived trauma related to psychiatric treatment and medication adherence in patients with schizophrenia. In this multicenter study, 72 patients were assessed regarding symptomatology, self-reported adherence with medication, insight, medication side-effects, therapeutic alliance and perceived trauma related to psychiatric treatment. Structural Equation Modeling (SEM) was used to test predicted paths among these variables. The data fit a model in which medication adherence…
Links between maternal feeding practices and children's eating difficulties. Validation of French tools
2012
Abstract: The main objectives of the study were to validate a measure of young children's eating difficulties and maternal feeding practices in a French sample, and to assess the links between these practices and children's eating difficulties. Mothers of French children aged 20-36 months completed 4 questionnaires that were validated using a Structural Equation Modelling approach. Links between children and maternal components were investigated using a PLS regression. The Children's Eating Difficulties Questionnaire yielded a 4-dimension solution: Neophobia, Pickiness, Low Appetite and Low Enjoyment in food. The Feeding Style Questionnaire assessed 3 dimensions: Authoritarian, Authoritativ…
Relationship between Burnout and Body Mass Index in Senior and Middle Managers from the Mexican Manufacturing Industry
2018
This research relates Burnout Syndrome (BS) with the Body Mass Index (BMI) among middle and senior managers of the Mexican manufacturing industry. Even though BS incidence is high in the Mexican industrial population, few systematic studies have explored BS and its relationship with other health problems, such as obesity. The goal of this research is to determine the relationship between BS and the BMI in employees with normal weight, overweight, and obesity. We present three structural equation models to relate BS and the BMI. The BMI ranges were determined according to the parameters (normal weight, overweight, and obesity) proposed by the World Health Organization (WHO). The sample inclu…
