Screen media time usage of 12-16 year-old Spanish school adolescents: Effects of personal and socioeconomic factors, season and type of day.
2007
Abstract This study examined screen media time usage (SMTU) and its association with personal and socioeconomic factors, as well as the effect of season and type of day, in a Spanish sample of 12–16 year-old school adolescents (N = 323). The research design was a cross-sectional survey, in which an interviewer-administered recall questionnaire was used. Statistical analyses included repeated measures analyses of variance, analysis of covariance and structural equation models. Results showed an average of 2.52 h per day of total SMTU and partial times of 1.73 h per day in TV viewing, 0.27 h per day in computer/videogames, and 0.52 h per day in mobile use. Four significant predictors of SMTU …
Depth and breadth of external knowledge search and performance: The mediating role of absorptive capacity
2015
Nowadays it is commonly accepted that exploiting external knowledge sources is important for firms' innovation and performance. However, it is still not clear how this effect takes place and what internal capabilities are involved in the process. We propose to open the black box between external knowledge search strategies, and innovation and performance by proposing absorptive capacity (AC) as the mediating variable. A sample of 102 biotechnology firms from Spain is used to test the proposed theoretical model through structural equation modeling taking the partial least squares approach. Results suggest that AC acts as a full mediator in the relationship between the depth of external knowl…
Job Characteristics, Recovery Experiences and Occupational Well-being: Testing Cross-lagged Relationships across 1 Year
2013
The aim of the present study conducted among 274 Finnish employees was to examine the relationships between job characteristics, recovery experiences and occupational well-being across 1 year. We hypothesized that these relationships would follow normal causation, that is, job characteristics at T1 predict recovery experiences (detachment, relaxation, mastery and control at off-job time) and well-being (fatigue at work and work engagement) at T2, and recovery experiences at T1 predict well-being at T2. The structural equation modelling analyses lent support to the hypothesized normal causation model compared with the reversed causation and reciprocal models. However, only the longitudinal r…
Cross‐national outcomes of stress appraisal
2012
PurposeThe present study aims to analyze the role of the appraisal of stressors as harmful and threatening (distress) and/or as opportunities and challenges (eustress) in inducing negative (burnout) and positive (engagement) effects. It compares appraisal of occupational stressors in Poland and Spain and looks for differences between these countries in the associations between different types of appraisals and their positive and negative outcomes.Design/methodology/approachThe study analyzes the equivalence of relations across cultures by constraining structural equation models to be equivalent across the Spanish (n=603) and Polish (n=147) data sets of social care services employees. Multig…
The Impact of Adolescent Internet Addiction on Sexual Online Victimization: The Mediating Effects of Sexting and Body Self-Esteem
2021
Adolescents’ problematic use of the internet and the risk of sexual online victimization are an increasing concern among families, researchers, professionals and society. This study aimed to analyze the interplay between adolescents’ addiction to social networks and internet, body self-esteem and sexual–erotic risk behavior online: sexting, sextortion and grooming. While sexting refers to the voluntary engagement in texting sexual–erotic messages, sextortion and grooming are means of sexual–erotic victimization through the use of the internet. Participants were 1763 adolescents (51% girls), aged 12 to 16 years (M = 14.56
Transformational leadership and depressive symptoms among employees : mediating factors
2014
Purpose– The purpose of this paper is to examine whether the link between transformational leadership and depressive symptoms among employees is mediated by such personal resources as occupational self-efficacy, perceived meaningfulness of the work, and work-related rumination.Design/methodology/approach– The study was conducted using questionnaires among 557 Finnish municipal employees in various occupations. The statistical analysis was based on structural equation modeling. A multiple mediation model enabled us to investigate the specific indirect effects of each mediator. Model comparison was applied to ascertain whether the mediation should be considered as full or partial.Findings– Re…
Students' Perception of School and Their Smoking and Alcohol Use: A Cross-National Study
2000
The objective of the paper is to study how 15 year old students' perceptions of the psychosocial environment in their schools, defined as student autonomy, teacher support, student support and demands, relate to smoking and alcohol use. Data from 15 year old students in Finland and Norway are included (n=2.816), using structural equation modelling to test theoretical models. The best model fitting the data shows that low student autonomy, low teacher support, student support and inadequate demands are significantly associated with health compromising behaviours directly, and indirectly through students' satisfaction with school. Low student autonomy is the strongest predictor of the four. T…
Executive Functions, Episodic Autobiographical Memory, Problem-Solving Capacity, and Depression Proposal for a Structural Equations Model
2019
The executive functions play an important role in storing and recovering autobiographical memories, especially episodic memories. These types of memories provide information about solutions and experiences from the past that can be utilized as examples in the present when seeking solutions to any problem. In addition, a close relationship between depression and the executive functions has been widely recognized. This study aims to elaborate a structural equations model that empirically supports the relationships among the executive functions, episodic autobiographical memory, and the adaptive capacity to solve problems, taking into account the depressed mood state. In all, 32 healthy elder…
Analyzing heterogeneity on the value, satisfaction, word-of-mouth relationship in retailing
2017
Purpose The literature recognizes the need to study differences in consumer behavior in highly competitive and dynamic markets. In this paper, the authors look at how the heterogeneous evaluation of retailing influences customer satisfaction and loyalty. The purpose of this paper is to analyze unobserved heterogeneity on customer value dimensions perceptions in retail establishments, and their potential effects on positive forms of behavioral outcomes considering customer satisfaction as a mediating variable. Design/methodology/approach On a sample of 820 retail customers, the authors apply a finite mixture structural equation modeling that analyzes unobserved heterogeneity simultaneously.…
Psychosocial Factors and Chronic Illness as Predictors for Anxiety and Depression in Adolescence
2020
Adolescence is a challenging time when emotional difficulties often arise. Self-esteem, good relationships with peers, and emotional competences can buffer the effects of these difficulties. The difficulties can be even greater when coupled with the presence of a chronic physical illness (CD). Our goal is to analyze psychosocial factors and CD as predictors for anxiety and depression. It was compared the results of structural equation models (SEM) with models based on qualitative comparative analysis (QCA) to analyze the possible influence of these variables on levels of anxiety-depression in adolescents with and without CD. The sample consisted of 681 adolescents, between 12 and 16 years o…
