The aim of this study was to establish a typology of employee well-being, together with its psychosocial antecedents and consequences. Results obtained with a sample of 786 full-time employees from different occupational sectors show four types of employee well-being: 9-to-5 or relaxed, work engaged or enthusiastic, workaholic or tense, and burned-out or fatigued, each having different relationships with job and personal characteristics. This study provides evidence of a parsimonious, theory-based classification of employee well-being and contributes to the existing literature about work investment because meaningful relations were found between various types of employee well-being, and heavy and soft work investors.

Purpose: To check for changes in sleep in three temporary times: before COVID-19 lockdown in university students, and also twenty days and forty days afterwards, as well as to see how it has influenced in their daily activities. Materials and Methods: A longitudinal study was conducted with a sample of 75 participants from different Spanish universities. The Pittsburgh Sleep Quality Index and the Adapted Interest List were administered to evaluate the main variables of the study. Results: About 70.7% of the sample showed worse sleep quality at 20 days, almost twice as much as before confinement (37.3%), there were more problems falling asleep (F(2, 75) = −3.14, p = 0.002), and more difficulty getting back to sleep when waking up at night (F(2.75) = 2.08, p = 0.037) at 40 days of lockdown. In addition, as confinement time went on, students showed less activities. Factors such as working, in addition to studying, and relaxing activities (reading, listening to music) were associated with better sleep quality. Conclusion: Sleep quality worsened during lockdown in university students, as well as both 20 and 40 days later. Staying busy during the day (not only studying but also working) and spending free time on relaxing activities are related to better sleep quality.

This study tests the relationship among workaholism (i.e. working excessively and compulsively), sleep problems and cardiovascular risk in 537 hospital employees. Four types of workers (i.e. workaholics, positive, compulsive and hard workers) were distinguished, comparing the health indicators. The results show that workaholics experience significantly more sleep problems (i.e. morning tiredness, sleeping while driving and sleeping fewer hours both on weekdays and at weekends, with poorer quality), have higher relative risk scores, and consume more caffeine and alcohol than the other patterns of workers (positive, compulsive and hard workers). Further analyses revealed that sleep problems fully mediated the relationship between workaholism (i.e. working excessively and compulsively) and cardiovascular risk. The present study emphasises the fact that being a workaholic might be a significant risk factor for having sleep problems and cardiovascular disease.

Taking the Resources-Experiences-Demands Model (RED Model)by Salanova and colleagues as our starting point, we tested how work self-efficacy relates positively to negative (i.e., work overload and work-family conflict) and positive outcomes (i.e., job satisfaction and organizational commitment), through the mediating role of workaholism (health impairment process) and work engagement (motivational process). In a sample of 386 administrative staff from a Spanish University (65% women), Structural Equation Modeling provided full evidence for the research model. In addition, Multivariate Analyses of Variance showed that self-efficacy was only related positively to one of the two dimensions of workaholism, namely, working excessively. Finally, we discuss the theoretical and practical contributions in terms of the RED Model. Keywords: self-efficacy, workaholism, work engagement.Tomando como base teórica el Modelo de Recursos-Experiencias-Demandas (Modelo RED) de Salanova y colegas, analizamos cómo la autoeficacia laboral se relaciona positivamente con resultados negativos (i.e., sobrecarga cuantitativa y conflicto trabajo-familia) y con resultados positivos (i.e., satisfacción laboral y compromiso organizacional), a través del rol mediador de la adicción al trabajo (proceso de erosión) y el engagement o vinculación laboral (proceso motivacional). En una muestra de 386 trabajadores PAS (Personal de Administración y Servicios) de una Universidad Española (65% mujeres), utilizando Ecuaciones Estructurales obtuvimos evidencia total para el modelo de investigación propuesto. Además, diversos Análisis Multivariados de Varianza mostraron que la autoeficacia se relacionaba positivamente solo con una de las dos dimensiones de la adicción al trabajo, esto es, trabajar excesivamente. Finalmente, discutimos las contribuciones teóricas y prácticas del estudio basándonos en el Modelo RED. Palabras clave: autoeficacia, adicción al trabajo, vinculación laboral.

Mindfulness-based interventions (MBI) are a recognized effective psychological practice characterized by attention control, awareness, acceptance, non-reactivity, and non-judgmental thinking obtained through the practice of meditation. They have been shown to be useful in reducing stress and enhancing well-being in different contexts. In this research, the effectiveness of an MBI was evaluated on variables that can promote successful job performance such as mindfulness trait, positive and negative affect, forgiveness, personality strengths and satisfaction with life. The intervention was carried out through a smartphone application called “Aire Fresco” (Fresh Air) during 14 days in the middle of the quarantine produced by the Covid-19 pandemic. The study sample was composed of 164 Spanish people who were distributed in two groups: control group and experimental group, which were evaluated before and after the intervention. The MANCOVA performed showed an overall positive effect of the intervention on the variables evaluated. The different ANCOVAs carried out showed that the intervention was beneficial in increasing mindfulness trait, reducing negative affect or increasing life satisfaction, among others. Our study is, as far as we know, the first to demonstrate the effectiveness of a brief intervention in mindfulness conducted using a smartphone application in Spanish.
