La mesure du stress en milieu professionnel avec l’échelle de stress perçu (Perceived Stress Scale): pertinence des versions en dix et quatre items

This article presents the psychometric qualities of the Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983) in ten- and four-item version. Our objectives are to verify if we find the main results of the literature as regards the ten-item version and to observe if the psychometric properties of the four-item version are enough good to use this questionnaire. The population of the study consists of 16853 employees working in French large companies. The analyses concern the structure of questionnaires, internal consistency, capacity to discriminate from groups of persons according to gender, age group and professional status, and the convergent validity of both versions. Our results show that 1) we find the main psychometric characteristics of the ten- item version described in the literature and 2) the four-item version presents qualities enough good to be used in an estimation of the perceived stress.     

Optimising retention through multiple study opportunities over days: The benefit of an expanding schedule of repetitions

Few studies have investigated how scheduling repeated studies of the same material over several days influences its subsequent retention. The study-phase retrieval hypothesis predicts that, under these circumstances, expanding intervals between repetitions will promote the greatest likelihood that the participant will be reminded of previous occurrences of the item, thus leading to a benefit for subsequent recall. In the present article, participants studied vocabulary pairs that were repeated according to one of three schedules. In the expanding schedule, pairs were presented on days 1, 2 and 13; in the uniform schedule, on days 1, 7 and 13; and in the contracting schedule, on days 1, 12 and 13. Cued-recall was assessed after a retention interval (RI) of 2, 6 or 13 days. Consistent with predictions, the expanding schedule generally led to better performance than the other schedules. However, further analyses suggested that the benefit of an expanding schedule may be greater when the RI is longer.     

Are smokers interested in genetic testing for smoking addiction? A socio-cognitive approach

Genetic advances have made genetically tailored smoking cessation treatments possible. In this study, we examined whether smokers are interested in undergoing a genetic test to identify their genetic susceptibility to nicotine addiction. In addition, we aimed to identify socio-cognitive determinants of smokers’ intention to undergo genetic testing. Following the protection motivation theory (PMT), we assessed the following constructs using an online survey among 587 smokers: threat appraisal (i.e. susceptibility and severity), fear, coping appraisal (i.e. response efficacy and self-efficacy), response costs and intention. In addition, knowledge, social norms and information-seeking behaviour were measured. Mean intention rates were 2.57 on a 5-point scale. Intention was significantly associated with threat appraisal and coping appraisal, as predicted by the PMT. Fear of the outcome was negatively associated with the intention to undergo genetic testing, but response costs, knowledge and social influence were not. Intention to undergo genetic testing in turn was positively related to seeking information about genetic testing and genetically tailored smoking cessation treatments. Smokers seem ambivalent or ‘on the fence’ with regard to undergoing a genetic test for smoking addiction. Socio-cognitive concepts such as susceptibility, severity, response efficacy and self-efficacy may be used to inform or educate smokers about the value of genetically tailored smoking cessation treatments.     

Increasing compliance with medical examination requests directed to children with autism: effects of a high-probability request procedure

The purpose of this study was to evaluate the effectiveness of a high-probability (high-p) request sequence as a means of increasing compliance with medical examination tasks. Participants were children who had been diagnosed with autism and who exhibited noncompliance during general medical examinations. The inclusion of the high-p request sequence effectively increased compliance with medical examination tasks. In addition, the procedure was efficient, could be implemented by parents and medical professionals, and did not involve aversive procedures.     

For love or money? What motivates people to know the minds of others?

Mood affects social cognition and "theory of mind", such that people in a persistent negative mood (i.e., dysphoria) have enhanced abilities at making subtle judgements about others' mental states. Theorists have argued that this hypersensitivity to subtle social cues may have adaptive significance in terms of solving interpersonal problems and/or minimising social risk. We tested whether increasing the social salience of a theory of mind task would preferentially increase dyspshoric individuals' performance on the task. Forty-four dysphoric and 51 non-dysphoric undergraduate women participated in a theory of mind decoding task following one of three motivational manipulations: (i) social motivation (ii) monetary motivation, or (iii) no motivation. Social motivation was associated with the greatest accuracy of mental state decoding for the dysphoric group, whereas the non-dysphoric group showed the highest accuracy in the monetary motivation condition. These results suggest that dysphoric individuals may be especially, and preferentially, motivated to understand the mental states of others.     

Assessing Private and Public Need for Uniqueness: Validation of French Versions of the Need for Uniqueness (NfU) and Self-Attributed Need for Uniqueness (SANU) Scales

Need for uniqueness represents the need for people to feel different and distinguish themselves from others. Two major scales exist that measure this need: the Need for Uniqueness scale (NfU; Snyder &; Fromkin, 1977 Snyder, C. R., &; Fromkin, H. L. (1977). Abnormality as a positive characteristic: The development and validation of a scale measuring need for uniqueness. Journal of Abnormal Psychology, 86, 518–527. https://doi.org/10.1037/0021-843X.86.5.518[Crossref], [Web of Science ®] , [Google Scholar]) and the Self-Attributed Need for Uniqueness scale (SANU; Lynn &; Harris, 1997b Lynn, M., &; Harris, J. (1997b). Individual differences in the pursuit of self-uniqueness through consumption. Journal of Applied Social Psychology, 27, 1861–1883. https://doi.org/10.1111/j.1559-1816.1997.tb01629.x[Crossref], [Web of Science ®] , [Google Scholar]). We propose here a French version of both scales. Through a dual approach of exploratory and confirmatory factorial analyses, we investigated the scales' structure in student samples from two French-speaking countries (France and Switzerland, N = 1,348) as well as measures of internal and external validity. Both scales presented good psychometric properties in French. Additionally, we investigated differences between the scales, as literature suggests that the NfU relies mostly on public and risky displays of uniqueness, whereas the SANU focuses on private and more socially acceptable means to acquire a feeling of uniqueness. Differences arose in the links with several personality characteristics (emotionality, extraversion, agreeableness, sensation seeking, and self-consciousness), suggesting that the NfU corresponds rather to a need to demonstrate uniqueness through public displays and the SANU to a need to feel unique through more private means. We discuss implications for research and provide advice on choosing by the scale most appropriate to the researcher's aims.     

Students’ Need Satisfaction Profiles: Similarity and Change over the Course of a University Semester

Self-determination theory positions the satisfaction of students’ needs for autonomy, competence, and relatedness as important determinants of various educational outcomes. In this study, we identify subpopulations of students characterized by distinct configurations of need satisfaction in the educational context, and assess the extent to which the nature of these configurations, and students’ individual profiles, remain stable over the course of a university semester. We also examine the role of perfectionism in the prediction of profile membership, and how these profiles relate to a variety of educational outcomes. A total of 521 first-year undergraduate university students completed our measures at the beginning and end of a university semester. We identified five need satisfaction profiles, which remained unchanged over the course of the study. Students characterized by higher levels of self-oriented perfectionism were more likely to be a member of a profile characterized by high levels of relatedness and global needs satisfaction associated with average levels of competence need satisfaction (“Globally Satisfied and Highly Connected” profile) relative to the other ones, and into the “Globally Satisfied” profile relative to the “Globally Dissatisfied, Highly Connected, and Competence Deficient” profile. Finally, the “Globally Dissatisfied, Highly Connected, and Competence Deficient” profile was associated with the least desirable outcomes (the lowest levels of students’ interest toward their studies, satisfaction, and attendance, and the highest levels of dropout intentions).     

Sociodemographic,Cognitive, and Emotional Determinants of Two Health Behaviors during SARS-CoV-2 Outbreak: An Online Study among French-Speaking Belgian Responders during the Spring Lockdown

To contain the SARS-CoV-2 infection rate, health authorities have encouraged the population to enhance protective behaviors such as physical distancing and handwashing. Behavioral sciences emphasize the role of sociocognitive determinants to explain health behaviors, while largely ignoring emotional factors. In a large online study (N > 4000), we investigated the role of sociodemographic, cognitive, emotional, and social factors that can facilitate or hinder handwashing and limitation of social contacts. Data were collected from March 18 until April 19, 2020, which corresponds to the spring lockdown and the first peak of the pandemic in Belgium. Logistic regressions showed that sociodemographic factors (gender, age, level of education) and the dimensions of the Theory of Planned Behavior (intentions, attitudes, perceived behavioral control and subjective norms) had a strong impact on health behaviors, but that emotional factors explained an additional part of the variance. Being more attentive/determined and frightened/anxious, along with scoring higher on health anxiety were related to a higher frequency of handwashing. In contrast, being enthusiastic/happy was related to lower adherence to limiting social contacts. Our results suggest that the type of predictors and the direction of associations depend on the type of health behavior considered. The role of specific emotional factors in addition to more classical predictors is discussed. The study offers new perspectives regarding the factors that are associated with the adherence to behaviors recommended to adopt when faced with a pandemic.     

Effect of marital satisfaction on self-regulation efforts in couples: Value of heart rate variability measurements

This study explored self-regulatory efforts during the viewing of couple interactions and their association with relationship satisfaction. High-frequency heart rate variability (HF-HRV) was measured for each participant during a video recall of a recent couple interaction to quantify the self-regulatory processes governed by parasympathetic activity. Among 30 couples, HF-HRV was measured continuously during three specific periods to explore its change over time using a video-recall procedure: (1) resting state; (2) viewing of couple interactions (expressing daily life situations and conflictual interactions); and (3) recovery. Results of multilevel models revealed a u-shaped pattern of HF-HRV responses for men and women across the three periods with a nadir at the midway through the process. This pattern of physiological change (vagal suppression) reflects a flexible response to a stressful situation. Nevertheless, the pattern of physiological responses varied according to the level of relationship satisfaction. Men who were more satisfied in their couple relationship presented greater vagal suppression than dissatisfied men. In contrast, no significant HF-HRV changes were found in women over the different periods of the video-recall procedure and no moderating effect of relationship satisfaction. We discuss the different patterns of physiological responses observed both for men and women in terms of interindividual variability according to the level of their relationship satisfaction. The present study highlights the important role of relationship satisfaction in regulatory processes.
