Satisfaction et confort au travail. L’apport de la démarche implicative

A large body of research has investigated the psycho-organizational variables predicting satisfaction at work, but few studies have so far examined variables in the field of environmental psychology. Our study aims first to identify the impact of variables evaluating comfort at work (satisfaction with the work environment, attachment to the workplace) by comparing them with organizational variables known to be related to job satisfaction, and then to rank the relationships between these variables in a pseudo- implication sequence, based on statistical implicative analysis. The study involved 105 bank employees and confirms our theoretical model, showing that job satisfaction can be explained implicatively by the three other variables [(Comfort/Functionality => Control/privacy) => Workplace attachment] => job satisfaction.     

What matters when children play: Influence of Social Cognitive Theory and perceived environment on levels of physical activity among elementary-aged youth

ObjectivesSocial Cognitive Theory (SCT) has often been used as a guide to predict and modify physical activity (PA) behavior. We assessed the ability of commonly investigated SCT variables and perceived school environment variables to predict PA among elementary students. We also examined differences in influences between Hispanic and non-Hispanic students.DesignThis analysis used baseline data collected from eight schools who participated in a four-year study of a combined school-day curriculum and environmental intervention.MethodsData were collected from 393 students. A 3-step linear regression was used to measure associations between PA level, SCT variables (self-efficacy, social support, enjoyment), and perceived environment variables (schoolyard structures, condition, equipment/supervision). Logistic regression assessed associations between variables and whether students met PA recommendations.ResultsSchool and sex explained 6% of the moderate-to-vigorous PA models' variation. SCT variables explained an additional 15% of the models' variation, with much of the model's predictive ability coming from self-efficacy and social support. Sex was more strongly associated with PA level among Hispanic students, while self-efficacy was more strongly associated among non-Hispanic students. Perceived environment variables contributed little to the models.ConclusionsOur findings add to the literature on the influences of PA among elementary-aged students. The differences seen in the influence of sex and self-efficacy among non-Hispanic and Hispanic students suggests these are areas where PA interventions could be tailored to improve efficacy. Additional research is needed to understand if different measures of perceived environment or perceptions at different ages may better predict PA.     

On-road trust and perceived risk in Level 2 automation

To encourage appropriate use of driving automation, we need to understand and monitor driver’s trust and risk perception. We examined (1) how trust and perceived risk are affected by automation, driving conditions and experience and (2) how well perceived risk can be inferred from behaviour and physiology at three levels: over traffic conditions, aggregated risk events, and individual risk events.30 users with and without automation experience drove a Toyota Corolla with driving support. Safety attitude, subjective ratings, behaviour and physiology were examined.Driving support encouraged a positive safety attitude and active driver involvement. It reduced latent hazards while maintaining saliently perceived risks. Drivers frequently overruled lane centring (3.1 times/minute) and kept their feet on or above the pedals using ACC (65.8% of time). They comfortably used support on curvy motorways and monotonic and congested highways but less in unstable traffic and on roundabouts. They trusted the automation 65.4%, perceived 36.0% risk, acknowledged the need to monitor and would not engage in more secondary tasks than during manual driving.Trust-in situation reduced 2.0% when using automation. It was 8.2% higher than trust-in-automation, presumably due to driver self-confidence. Driving conditions or conflicts between driver and automation did not affect trust-in-automation.At the traffic condition level, physiology showed weak and partially counter-intuitive effects. For aggregated risk events, skin conductance had the clearest response but was discernible from baseline in  < 50%. Pupil dilation and heart rate only increased with strong braking and active lane departure assist. For individual risk events, a CNN classifier could not identify risk events from physiology. We conclude that GSR, heart rate and pupil dilation respond to perceived risk, but lack specificity to monitor it on individual events.     

The interplay of actual and perceived physical fitness in children: Effects on motivation and physical activity

From a sport and exercise psychology perspective, both the actual and perceived physical fitness become important for motivation towards physical activity and persistent physical activity in children no later than middle childhood (Stodden et al., 2008). To date, the effects of actual and perceived physical fitness have been investigated from a variable-centered approach (Jekauc et al., 2017). However, within this approach, the accuracy of the perceived physical fitness remains unconsidered. As actual and perceived physical fitness levels can be divergent, especially in children due to greater egocentricity and hence less comparison processes (Harter, 2006), also the accuracy of perceived physical fitness should be considered.In total, 462 children from 3rd and, approximately nine months later, from 4th grade participated in this study (M_age = 8.79 years). Third-grade students were assessed on their actual physical fitness, perceived physical fitness, and physical activity. In fourth grade, students were asked to fill out questionnaires that assess motivational regulations and physical activity. Polynomial regressions with response surface analyses were conducted to analyze main effects and accuracy effects of actual and perceived physical fitness on motivation and physical activity. Analyses revealed that children with higher actual and perceived physical fitness levels show greater autonomous motivation, higher current physical activity levels and higher physical activity levels nine months later. In addition, children who perceive their physical fitness more accurately show more current physical activity. Results indicate that the interplay between actual and perceived physical fitness does not only have an effect on physical activity but also on autonomous motivation, which is a predictor for long-term physical activity. Therefore, intervention should focus on the promotion of actual and perceived physical fitness. In addition, the ability to accurately assess fitness should be promoted in this age group.     

Personality perceptions and relationship satisfaction in couples

The present study investigates how perceptions of personality are related to relationship satisfaction in an age-heterogeneous sample of romantic couples. Self- and partner-perceptions as well as perceived similarity and self-other agreement were examined separately for the Big Five personality traits. Results of Actor–Partner-Interdependence Models revealed substantial effects of partner-perceived personality in all Big Five traits on both partners’ relationship satisfaction. In contrast, effects of self-perceived personality on relationship satisfaction were small. Over and above self- and partner-rated personality, perceiving one’s partner as similar to oneself made a small unique contribution to relationship satisfaction in couples. These results emphasize the importance of integrating self- and partner-perceptions of personality for relationships outcomes.     

Apoyo social en universitarios españoles de primer año: propiedades psicométricas del Social Support Questionnaire-Short Form y el Social Provisions Scale

Perceived social support is a multifaceted construct conceptualized as one's cognitive appraisal as to the existence of a connection to others, based on trust, on whom one can rely on when necessary. The aim of this paper is to examine the psychometric properties of perceived social support, using the following scales: Social Support Questionnaire-Short Form (SSQ6) and Social Provisions Scale (SPS), on a sample of 855 first year university students – 575 females and 280 males – enrolled in 16 professional degrees at the University of Santiago de Compostela (Spain). The SSQ6 Scale assesses the dimensions of perceived support availability and satisfaction, whilst the SPS Scale assesses its social support functions. The factor analysis conducted confirms the SSQ6 Scale's two-dimensional model and the SPS Scale's six-factor structure. Internal consistency of both scales is satisfactory, as is the evidence of validity obtained from the correlations between the two scales and their subscales. The results reveal that the Spanish version of the SSQ6 and SPS scales are reliable and valid measurements for assessing perceived social support amongst university students.     

Relationships among perceived psychological growth,resilience and burnout in physicians

The purpose of this study was to examine the relationships between perceived growth as a physician (i.e., positive psychological changes experienced as a result of the professional experience) and burnout after controlling for the effects of perceived family support, dispositional resilience, age, and marital status among physicians. Physicians (n = 289) rated perceived support from family and completed the short form of the Posttraumatic Growth Inventory, the Resilience Scale, and Maslach Burnout Inventory. Results of hierarchical regression analyses revealed that the addition of perceived growth significantly improved prediction of resilience and perceived family support for burnout, showing that higher growth, resilience, and family support all were associated with lower levels of burnout. Moreover, the effects of growth on depersonalization, a domain of burnout, were stronger for physicians who perceived a lower level of family support, whereas the effects of growth on personal accomplishment, another domain of burnout, were stronger for physicians who showed a lower level of dispositional resilience. Current results have clinical implications for understanding protective factors for burnout, that is, a sense of personal growth may be a key factor for physicians who may be less resilient or may not perceive strong family support.

How Patient-Perpetrated Workplace Violence Leads to Turnover Intention Among Nurses: The Mediating Mechanism of Occupational Stress and Burnout

This study looked into the impact of patient-perpetrated workplace violence on nurses’ turnover intention by examining the sequential mediation effect of occupational stress and burnout. Results were obtained by analyzing the data collected from 216 nurses working in four public hospitals of central Pakistan. Results provided full support to the research hypotheses, demonstrating that patient-inflicted violence negatively affects nurses’ turnover intention, and that occupational stress and burnout both individually mediate the patient violence–turnover intention relationship. Particularly, the results illustrated that patient violence is related to turnover intention through occupational stress first and then burnout. These results widen the focus of past research by demonstrating that the patient violence–turnover intention link is not as simple as previously believed. Future researchers can use these findings to further develop integrated models that explore the adverse consequences of workplace violence on nursing staff’s personal and professional well-being.     

Stress perçu et santé physique des doctorants dans les universités françaises

Few studies have focused on PhD students in France despite the fact that this population appears to be particularly vulnerable to stress and often faces precariousness. This research investigated associations between socio-demographic factors, health behaviours, perceived stress and physical health in a wide sample of PhD students (n = 1923) in order to have a better understanding of this population's specificities. Our results indicated that stress is a critical issue among PhD candidates. Predictors of perceived stress were: gender, age, satisfaction with supervision, sleep quality and sports practice. Findings from this study confirm the relevance of the transactional model to investigate students’ health issues and suggest that physical activity and stress management should be encouraged through health promotion programs.
