Development of a revised version of the transdiagnostic skills scale (T2S-R).

Introduction: The transdiagnostic approach has been shown to offer promising prospects in psychopathology, based on the observation that common factors may be involved in different psychiatric disorders. The transdiagnostic skills scale (T2S) was developed recently to assess the skills that are disrupted in these disorders. However, studies have shown that the T2S has lower predictive power for externalizing than internalizing disorders. This may be due to the fact that the skills assessed do not include the control of urges and cravings. The aims of the current study are thus to develop a revised version of the T2S (T2S-R) integrating this dimension, and to assess its factor structure and invariance across employment status (workers vs. students) and the level of psychopathology. Method: We recruited 1,298 French participants online through social media. They completed the revised version of the T2S and the symptomatic transdiagnostic test (S2T), which evaluates 11 clusters of psychiatric symptoms. We assessed the factor structure, internal consistency, invariance, and predictive validity of the revised T2S. Results: We found a good fit for a bifactor exploratory structural equation modeling (B-ESEM) approach including a global skills factor and seven specific factors. The results also indicate that the new dimension (i.e., control of urges and cravings) has good predictive value, especially for externalizing problems. We also found total invariance of the scale across employment status and partial invariance across the level of psychopathology. Conclusion: The revised version of the T2S-R has good psychometric properties. It predicts better externalizing problems than the original version. However, the scale remains more correlated with internalizing than externalizing problems. We discuss the implications of the results on the transdiagnostic conceptualization and the interest of using a mixed approach combining transdiagnostic and diagnostic analyses.

In vitro digestion of two protein-rich dairy products in the ageing gastrointestinal tract.

It is still unclear if changes in protein digestibility and absorption kinetics in old age may affect the anabolic effect of high-protein foods. The objective of this study was to investigate the digestion of two high-protein (10% w/w) dairy products in vitro: a fermented dairy product formulated with a ratio of whey proteins to caseins of 80 to 20% (WBD) and a Skyr containing mainly caseins. The new static in vitro digestion model adapted to the general older adult population (≥65 years) proposed by the INFOGEST international consortium was implemented to investigate the digestion of these products and compared with the standard version of the protocol. Kinetics of proteolysis was compared between both models for each product, in the gastric and intestinal phases of digestion. Protein hydrolysis was studied by the OPA method, SDS-PAGE, and LC-MS/MS, and amino acids were quantified by HPLC. Protein hydrolysis by pepsin was slower with the older adult model than with the young adult model, and consequently, in spite of a longer gastric phase duration, the degree of proteolysis (DH) at the end of the gastric phase was lower. Two different scenarios were observed depending on the type of dairy product studied: -10 and -40% DH for Skyr and WBD, respectively. In the intestinal phase, lower concentrations of free leucine were observed in older adult conditions (approx. -10%), but no significant differences in proteolysis were observed overall between the models. Therefore, the digestion conditions used influenced significantly the rate and extent of proteolysis in the gastric phase but not in the intestinal phase.

A New Gain Spiral at Work: Relationships between Virtuous Organizational Practices, Psychological Capital, and Well-Being of Workers.

Identifying antecedents of well-being at work is an active field of research, focusing notably on organizational practices that promote employees' optimal health. To date, whereas studies have demonstrated that some organizational practices, considered in isolation, are positively associated with indicators of well-being, none tested the joint effect of a bundle of practices on these. Moreover, few studies have examined the psychological mechanisms underlying these relationships. The present study aimed to identify the relationships between virtuous organizational practices, a new psychological integrative construct, and three indicators of workers' hedonic, eudaimonic, and social well-being, namely job satisfaction, thriving at work, and work-life balance, and to test the mediational role of psychological capital in these relationships. The sample comprised 400 French employees working in non-profit, private, and public organizations. Structural equation modeling confirmed the direct effects of virtuous organizational practices on the three indicators of well-being, and a bootstrapping procedure demonstrated that psychological capital partially mediates these relationships. The results of this study have many practical applications because virtuous organizational practices can easily be implemented and optimized in work organizations to develop the individual resources of workers and, in detail, to promote their psychological well-being. Finally, the contributions of this study, avenues for future research, and limitations are discussed.

How Can Students' Entrepreneurial Intention Be Increased? The Role of Psychological Capital, Perceived Learning From an Entrepreneurship Education Program, Emotions and Their Relationships.

Entrepreneurship education has become a major focus of interest for researchers and national policy makers to encourage students to pursue entrepreneurial careers. The research on entrepreneurship education-entrepreneurial intentions (EIs) has yielded mixed results, and indicates the need to focus on antecedents of EI. More precisely, the aim of this paper was to examine antecedents of students' EI in French entrepreneurship education programs. Participants were 460 French university undergraduates. Structural equation modeling results revealed that students' Psychological Capital (PsyCap) had a significant positive relationship with perceived learning from the program and a significant negative relationship with negative emotions related to entrepreneurial actions. They also show that PsyCap indirectly enhanced EI. More precisely, students with high PsyCap learned more from the program in terms of perceived skills and knowledge and in turn had a higher EI. Moreover, students with high PsyCap had less entrepreneurial action-related doubt, fear and aversion, which also increased EI. This decrease in negative emotions can be explained notably by what students perceived they had learned from the program. This article concludes with the implications of these findings for future research and practical applications.

Virtuous Organizational Practices: A New Construct and a New Inventory.

Research on the identification of organizational practices that promote individual and organizational performance is now very extensive. However, several studies have revealed the dark side of these practices on employees' psychological health. Consequently, researchers have called on the scientific community to focus on the well-being of workers and to identify the organizational practices that promote it. Thus, the aim of the present research was to fill this gap by introducing a new conceptualization of organizational practices supporting the psychological health of employees and proposing a new improved measure to assess them. Drawing on the American Psychological Association's model of Psychologically healthy workplace, we first conceptualized the innovative multidimensional construct of virtuous organizational practices. We then conducted four studies (N = 1,407) to develop and validate the Virtuous Organizational Practices inventory. Results of exploratory statistical analyses provide strong evidence of the second-order factor structure of the inventory in different French samples and of the convergent, predictive and incremental validity of this tool. Implications for researchers, organizations and practitioners and avenues for future research are discussed.

An explanatory model of authentic leadership, flourishing and work-family balance of nurses in French hospitals.

PURPOSE: This study aims to investigate the relationship between a positive leadership style [i.e. authentic leadership (AL)] and nurses' psychological health (i.e. nurses' flourishing and satisfaction with work-family balance), including psychological capital (PsyCap) as a mediational variable. DESIGN/METHODOLOGY/APPROACH: A cross-sectional study was conducted with a self-report questionnaire including 1,076 nurses from public and private hospitals in France. FINDINGS: Structural equation modeling results revealed that AL is related to nurses' flourishing and satisfaction with work-family balance and that PsyCap acted as a partial mediator between this leadership style and positive outcomes. PRACTICAL IMPLICATIONS: This research indicated that hospitals can enhance nurses' psychological health not only in their work but also in their lives in general by improving leaders' authentic management style and developing PsyCap (e.g. staffing, training and development). ORIGINALITY/VALUE: An original feature of this paper concerns its focus on the mediating role of PsyCap in the relationship between AL and these positive outcomes. Moreover, this study underlined the influence of leadership style on nurses' psychological health beyond occupational health. The research makes a valuable contribution to the existing AL literature by establishing a new explanatory model of AL and nurses' psychological health in the French context. It also highlights the interest in developing this leadership style in health-care settings.

The Participatory Approach: A Specific French Organizational Model at the Department Level to Serve the Quality of Work Life of Healthcare Providers and the Quality of Care in Pediatric Oncology.

BACKGROUND: Care providers 'psychological health at work is an important issue because it directly affects the quality of patient care. So far, few studies have studied the psychological health at work of care providers in paediatric oncology. The participatory approach (PA) is an innovative organizational model of department specific to France and previously associated with quality of work life (QWL) and job performance. The aim of the present study was to explore the relationships between the participatory approach, care providers' QWL and quality of care of children in pediatric oncology departments in France. METHODS: A multicentre survey was carried out in pediatric cancer units in France. Care providers completed a questionnaire assessing PA, QWL, consequences of QWL, and their perception of quality of care. The children or their parents completed a questionnaire assessing their perception of quality of care. RESULTS: Five hundred and ten healthcare professionals working in French pediatric oncology centres (more than 40% of the healthcare staff in paediatric oncology in France), 142 children and 298 parents responded to the survey. PA was associated with the care providers' QWL (ß = 0.274; p <0.001), work engagement (ß = 0.167; p<0.001), job satisfaction (ß = 0.166; p<0.001) and perception of quality of care (ß = 0.236; p<0.001). PA was also related to patients' perception of quality of care notably regarding quality of communication (ß = 0.161; p<0.001) and information (ß = 0.226; p<0.001). CONCLUSION: PA is an innovative organizational model that appears to play a role in all aspects of healthcare providers' QWL, and in the quality of care perceived by both care providers and patients.

Validation of the French Psychological Capital Questionnaire (F-PCQ-24) and its measurement invariance using bifactor exploratory structural equation modeling framework.

The general purpose of this study was to validate the French Psychological Capital Questionnaire (F-PCQ-24) in a French Air Force sample (N = 3,665). One specific aim was to verify what the best measurement model is for PsyCap, notably by using Bifactor Exploratory Structural Equation Modeling (B-ESEM). Another specific aim was to examine the measurement invariance of the best fitting model for the F-PCQ-24 across gender, rank and tenure. Results supported the superiority of the B-ESEM model of PsyCap with the hope dimension divided into its two components (will-power and way-power). Moreover, multi-group confirmatory factor analyses indicated the measurement invariance of F-PCQ-24 for gender and tenure, while there was a small problem with measurement invariance for rank. Overall, these findings confirm that the F-PCQ-24 is a stable measure of PsyCap and support previous theoretical considerations that PsyCap is a core construct. Implications of these findings, limitations and directions for future research are discussed.

Relationships Between Managerial and Organizational Practices, Psychological Health at Work, and Quality of Care in Pediatric Oncology.

PURPOSE: Psychological health at work for care providers is an important issue, because they are directly involved in quality of patient care. Managerial and organizational determinants have been found to be indicators of psychological health at work. The main objective of this study was to explore the relationships between the psychological health at work of pediatric oncology care workers with managerial and organizational determinants and with quality of care. MATERIALS AND METHODS: We performed regression analysis between psychological health at work (quality of work life [QWL], job satisfaction, and so on), managerial determinants (transformational leadership, perceived autonomy support), organizational determinants (organizational support, organizational justice, and participatory approach), and perceived quality of care. RESULTS: Participants were 510 health care professionals working in French pediatric oncology centers. No significant differences in the psychological health at work of the participants were found based on age, sex, length of employment, or professional discipline. In simple regression, significant associations were found between psychological health at work with all managerial and organizational determinants. In multiple regression, a significant link was found between QWL and perceived organizational support (ß = .21; P < .001), organizational justice (ß = .20, P < .001), and overall participatory approach (ß = .10; P < .02). Job satisfaction was also related to perceived organizational support (ß = .16; P < .01). Finally, perceived quality of care was linked to QWL (ß = .15; P < .01) and job satisfaction (ß = .30; P < .001). CONCLUSION: These results emphasize the importance of the role of managers and the organization in psychological health at work of health care providers and also in the quality of patient care.

On the Value of Considering Specific Facets of Interactional Justice Perceptions.

This research seeks to verify the value of considering specific perceptions of informational and interpersonal justice over and above employees' global perceptions of interactional justice. In Study 1 (Sample 1: n = 592; Sample 2: n = 384), we examined the underlying structure of workers' perceptions of interactional justice by contrasting first-order and bifactor representations of their ratings. To investigate the true added value of specific informational and interpersonal justice perceptions once global interactional justice perceptions are taken into account, we also considered the relations between these global and specific perceptions and various outcomes. Our findings revealed that workers' perceptions of interactional justice simultaneously reflected a global interactional justice factor and two specific facets (interpersonal and informational justice). In Study 2, we identified employees' latent justice profiles based on their global (interactional justice) and specific (interpersonal and informational justice) levels of interactional justice. Five different interactional justice profiles were identified: low interpersonal, high interpersonal/average informational, high informational, normative, and high interpersonal/low informational. Employees' perceptions of transformational leadership are a significant predictor of profile membership. Finally, the five profiles were significantly associated with anxiety and emotional exhaustion.

Better Understanding the Workers' Retirement Decision Attitudes: Development and Validation of a New Measure.

The aim of the present research was to develop a measure that could be used in future research for in-depth study of the psychological management of retirement. We report the results of six studies involving 1,898 French workers designed to develop and assess the psychometric properties of a new instrument named the Workers' Retirement Motivations Inventory (WRMI) using the push pull anti-push anti-pull model. The items were constructed based on a review of the relevant psychological literature and face-to-face interviews with senior workers. A combined method of exploratory structural equations modeling and confirmatory factor analysis (CFA) was employed and provided evidence for validating this structure of the inventory. The WRMI showed consistency of the four-factor structure across different samples, internal consistency, test-retest reliability, and predictive validity of workers' plans for retirement. Implications of these findings and avenues for counseling activities and future research are discussed.

Investigating the longitudinal effects of surface acting on managers' functioning through psychological needs.

This study is based on the premise that managers are expected to regulate their emotions in the form of surface acting. More specifically, drawing on self-determination theory, we explored the role of psychological needs for autonomy, competence, and relatedness in explaining the influence of surface acting on supervisors' job satisfaction and work engagement over time. Data were collected at 2 time points, over a 3-month period, from a sample of 435 French managers working in the health care industry. Results revealed that surface acting negatively predicted managers' job satisfaction and work engagement over time, through the satisfaction of their psychological needs. However, managers' need thwarting did not explain these positive outcomes. Overall, these findings provide insight into the longitudinal adverse effects of managers' surface acting on their functioning and corroborate the distinct role of psychological need satisfaction and thwarting. Theoretical contributions and perspectives, as well as implications for practice are discussed. (PsycINFO Database Record

Antimicrobial Susceptibility among Urban Wastewater and Wild Shellfish Isolates of Non-O1/Non-O139 Vibrio cholerae from La Rance Estuary (Brittany, France).

The early 2000s marked the end of the Golden age of the antibiotics and the beginning of the awareness on the potential threat to human health due to the dissemination of antimicrobial resistance. As a base-line study, we investigated the antimicrobial susceptibility of 99 strains of non-O1/non-O139 Vibrio cholerae isolated from wastewater and shellfish in 2000/2001 within La Rance estuary (Brittany, France). All isolates were susceptible to amoxicillin-clavulanic acid, cefotaxime, imipenem, chloramphenicol, nalidixic acid, ciprofloxacin, norfloxacin, amikacin, gentamicin, tetracycline, doxycycline, trimethoprim-sulfamethoxazole, and erythromycin. The only resistances were to streptomycin, sulfonamides and ampicillin: 54.6% of the isolates had acquired resistance to at least one antimicrobial agent among them and only six isolates from cockles were multidrug resistant. On the basis of the distribution of a limited selection of resistance associated genes, our study shows that V. cholerae can constitute an environmental reservoir for these genes. However, none of our isolates harbored integron. This result casts doubt on the capacity of non-O1/non-O139 V. cholerae to acquire resistance-associated genes in such context, and on its potential role of indicator of the dissemination of antimicrobial resistance in the aquatic environment.

Organizational and Managerial Resources and Quality of Care in French Pediatric Oncology Nursing.

The purpose of this study was to examine the relationships between nurses' organizational and managerial resources (ie, perceived organizational support and transformational leadership) and their quality of patient care, and second, the mediating role of job satisfaction in these relationships. Participants were 510 nurses from 25 out of 29 French pediatric oncology units. Structural equation modeling results revealed that perceived organizational support and transformational leadership were related to nurses' perceived quality of care and that job satisfaction acted as a mediator between these 2 antecedents (ie, organizational and managerial determinants) and this outcome (ie, quality of care). Based on these findings, practical suggestions and directions for future research are discussed.

Isolation and characterization of a psychrotolerant toxin producer, Bacillus weihenstephanensis, in liquid egg products.

A psychrotolerant bacteria of the Bacillus cereus group was found responsible for the spoilage of whole liquid egg products. By sequencing a 16S rRNA region and performing a PCR amplification of specific 16S rRNA and cspA signatures, a Bacillus weihenstephanensis was identified. Characterization of this strain shows its ability to grow in defined medium as well as in whole liquid egg at refrigerated temperatures. The strain isolated possesses genes encoding for hemolysin BL, nonhemolytic enterotoxin, and B. cereus enterotoxins and produces enterotoxins with cytotoxic activity in whole liquid egg, even at refrigerated temperatures. The isolate exhibits a clear ability to stick and form biofilms on stainless steel, the most common material used in egg breaking factories, as well as on model hydrophilic (glass) and hydrophobic (polytetrafluoroethylene) materials. These findings show the necessity to monitor for Bacillus contamination in egg products that are often used in the composition of particularly susceptible finished products such as cream, dessert, dairy, meat, and seafood.
