Risk and protective factors for pre- and postnatal bonding

Since disturbances in the mother–child bond increase the risk of negative consequences for child development, it is important to identify risk and protective factors for bonding as well as longitudinal associations. Previous research has used different bonding instruments during pregnancy and the postnatal phase, leading to inconsistent results. In the current study, the same instrument was used during the various phases. In a large, community-based sample (N = 793), general information, feelings of pre- and postnatal bonding (Pre- and Postnatal Bonding Scale), depressive symptoms (Edinburgh Postnatal Depression Scale), and partner support (subscale Tilburg Pregnancy/Postnatal Distress Scale) were measured at both 32 weeks of pregnancy and 8 months postnatally. Partner support was found to be a protective factor for suboptimal pre- and postnatal bonding, as was the engagement with fetal movements for prenatal bonding. High maternal educational level was a risk factor for suboptimal prenatal bonding, as were depressive symptoms for suboptimal postnatal bonding. The associations between most prenatal determinants and postnatal bonding were mediated by prenatal bonding, which underlines the importance of promoting prenatal bonding. Professionals in clinical practice should be aware of partner support, engagement with fetal movements, and postnatal depressive symptoms: All these factors offer opportunities for improving the bonding processes.     

Le comportement de « prise de parole » (voice) : validation de la version française de la mesure de Maynes et Podsakoff

Voice is an essential behaviour that can inhibit or generate processes of innovation and organisational change. To date, few measurement scales adapted to the French context and allowing to analyse this behaviour exists. This article proposes to translate the 4’factors Voice scale from Maynes and Podsakoff (2014). The translation of this scale was tested by 4 studies on different samples of 1275 French workers from various organisational backgrounds. The first studies test the reliability, internal consistency, divergent and convergent validity of the scale. Then, a gender invariance analysis tests the metric properties of the scale. The results obtained present acceptable psychometric qualities that validate the French version.     

Effect of security and trustworthiness for a fuzzy cluster management system in VANETs

Recently, smart cities and Internet of Things (IoT) applications, such as Vehicular Ad-hoc Networks (VANETs) and Opportunistic networks have been deeply investigated. However, these kinds of wireless networks have security problems. Also, the vehicles can be not trustworthy, which brings different communication problems. In this work, we present a Fuzzy Cluster Management System (FCMS) for VANETs. We present and compare two fuzzy-based system models: FCMS1 and FCMS2 for clustering of vehicles in VANETs. For FCMS1, we use three input parameters: Vehicle Relative Speed with Vehicle Cluster (VRSVC), Vehicle Degree of Centrality (VDC) and Vehicle Security (VS). The output parameter is Vehicle Remain or Leave Cluster (VRLC). For FCMS2, we consider four input parameters by adding Vehicle Trustworthiness (VT) as a new parameter. We evaluate both systems by simulations. The simulation results show that vehicles with the same VRSVC and with high VDC, VS and VT values have higher possibility to remain in the cluster. By comparing FCMS1 and FCMS2, we found that the FCMS2 can manage better the vehicles in the cluster than FCMS1.     

The Sociocultural Attitudes Toward Appearance Questionnaire (SATAQ-3): reliability and normative comparisons of eating disordered patients

The Sociocultural Attitudes Toward Appearance Questionnaire-3 (SATAQ-3) is a measure of one’s endorsement of societal appearance ideals. The measure has received extensive evaluation in normative samples, but only minimal evaluation in clinical groups. In this study, 440 patients with eating disorders completed the SATAQ-3. Internal consistencies were excellent for the four SATAQ-3 subscales. Groups did not differ by diagnosis on the Information subscale, however, individuals with bulimia nervosa scored higher than individuals with both subtypes of anorexia nervosa (restricting and binge eating/purging) on levels of Internalization-General and Internalization-Athlete. The findings provide informative normative data, along with preliminary results indicative of the potentially greater role of media messages and images in the formation and/or maintenance of bulimia nervosa than anorexia nervosa.     

Anxiety symptoms in Japanese and in German children

The purpose of this study was to compare the frequency of anxiety symptoms and their association with gender and age in Japanese and German children using the Spence Children's Anxiety Scale (SCAS). A total of 1837 children (862 from Germany and 975 from Japan) between the age of 8 and 12 years were investigated. Results revealed that German children reported significantly higher symptoms of separation anxiety, social phobia, obsessive compulsive disorder, and generalized anxiety disorder than Japanese children. Conversely, Japanese children reported significantly higher scores on symptoms related to physical injury fear. In both countries, girls scored higher than boys on all the scales of the SCAS. Symptoms of separation anxiety and panic decreased with age, whereas social phobia increased with age. The findings underscore the impact of culture on children's anxiety.     

Development and validation of a novel instrument to measure pedestrians’ smartphone use: The Smombie Scale

This study aimed to develop and verify the psychometric properties of the Smombie Scale, a new instrument to measure pedestrians’ smartphone use. The instrument development process comprised two phases: instrument development and psychometric evaluation. Data were collected from September to October 2020 using the “Invite” panel aggregator. The link to the online questionnaire was sent via smartphone text message to 400 young adults aged 18–39 years and yielded 398 valid responses. We randomly selected 200 participants for the exploratory factor analysis; the remaining 198 participants were selected for confirmatory factor analysis. The Smombie Scale comprises 15 items and four factors: (a) perceived risk; (b) stationary smartphone use, always on the smartphone; (c) pending instant message; and (d) smartphone dependency. Model fit was statistically significant (χ²/df = 2.20). The analyses indicated a sufficient goodness-of-fit index of 0.93, a comparative goodness-of-fit index of 0.95, a normed fit index and Tucker–Lewis index of 0.91, and a root mean square error of approximation of 0.07. The scale was also found to have sufficient reliability (Cronbach’s alpha = 0.83). The newly developed Smombie Scale is valid and reliable in measuring pedestrians’ smartphone use among young adults. The Smombie Scale shows evidence of being suitable for evaluating smartphone-distracted pedestrians. Its results can provide data for drafting educational programs to prevent smombie behaviors and deal with potential risks.     

Measuring attachment security via the Security Scale: Latent structure,invariance across mothers and fathers and convergent validity

The Security Scale (SS) is a widely used questionnaire measuring attachment towards mother and father in school-aged children. Whilst existing evidence supports concurrent and discriminant validity of the SS, its factorial structure remains largely underexplored. The current study examined the factorial structure of the SS, explored its measurement invariance across mother and father, and evaluated its convergent validity with the Coping Strategies Questionnaire in a sample of 149 Italian children aged 8–10 years. In statistical analyses, we accounted for the ordinal nature of the data and adopted an ad hoc bootstrap procedure for the estimation of measurement invariance. Results supported the factorial validity of the SS and the structural invariance of its underlying construct across parents. Evidence for convergent validity was also found. Overall, the Italian version of the SS is a promising tool to assess attachment in school-aged children.     

Driver anger in France: The relationships between sex,gender roles,trait and state driving anger and appraisals made while driving

This study aimed to further understand the relationships between sex, gender identity, trait and state driving anger and situational appraisals made while driving, and to validate the 33-item Driving Anger Scale (DAS) in a sample of drivers from France. In total, 378 drivers (males = 38%) aged from 18 to 79 years completed a survey containing the 33-item DAS, the Bem Sex-Role Inventory (BSRI) and eight questions regarding self-reported state anger and appraisals in relation to a recalled recent anger provoking situation experienced while driving. Confirmatory Factor Analysis supported the original six-factor structure of the 33-item DAS. Moreover, Structural Equation Modelling of the factors associated with the recalled anger event showed that trait anger influenced state anger through negative appraisal tendencies, and this was influenced by both sex and gender roles. Females and those reporting more masculine traits tended to have higher levels of trait driving anger. Conversely, drivers with feminine traits had low state anger except if they negatively appraised the situation. This new model could be taken into consideration for developing interventions to reduce anger and “road rage” incidents.     

Measuring decentering as a unidimensional construct: The development and initial validation of the Decentering Scale for Sport

Decentering, the ability to observe one's thoughts and feelings from a detached view, has gained increased attention in recent years. With this renewed interest comes a need for a reliable and valid tool to measure decentering in sport contexts. Therefore, in this multi-study paper we report the development and initial validation of a sport-specific self-report measure of decentering, the Decentering Scale for Sport (DSS). Based on an initial pool of context-specific items with acceptable content validity, a unidimensional decentering construct was confirmed in four independent athletic samples (n = 1255). Satisfactory internal consistency reliability and partial measurement invariance across gender and sport type was demonstrated. Convergent and concurrent validity of the DSS was established by showing positive and medium to large associations with mindfulness, well-being, flow, vitality, enjoyment and positive affect, and negative and medium to large associations with cognitive fusion, experiential avoidance, anxiety and negative affect. Discriminant validity of decentering with mindfulness and self-compassion was also established. Findings suggest that the DSS is a reliable and valid measure of decentering in sport contexts, and can be applied in future research and applied practice to measure decentering.
