Validation française de l’échelle de mesure de l’orthorexie ORTO-15 et étude des liens avec les troubles des conduites alimentaires et l’image du corps

IntroductionAlthough orthorexia is described as a pathological obsession over healthy food, its nature remains unclear. The results of the majority of studies, mainly using the ORTO-15 measurement scale, remain limited to certain countries and cannot be generalized to every culture. Furthermore, recent studies suggest that body image should be included in the orthorexia research, in addition to eating disorders.ObjectiveThe aim of this study was to propose a French adaptation of the ORTO-15 measurement scale using the Vallerand's transcultural validation procedure, explore its psychometric properties and the links between orthorexic behvaiour, symptoms of eating disorders and body image.MethodFour hundred and nine young adults (89% female), aged 18 to 25 years, completed the online version of the following scales: ORTO-15, Dunn et al. criteria (2016), the Eating-Attitudes Test (EAT-26), Binge Eating Scale (BES) and the Multidimensional Body Self Relations Questionnaire-Appearance Scale (MBSRQ-AS). Exploratory and confirmatory factor analysis (EFA and CFA, respectively) were carried out on two randomly split samples and links between different variables were explored using Spearman correlation coefficients.ResultsThe EFA yielded a single-factor 11-items structure explaining 24% of variance. The adjustment indices from the CFA were excellent. The stability of the scale was satisfactory (ICC = 0.71), despite a questionable internal consistency (α = .50). Links with other scales indicated good structural validity.ConclusionORTO-11-Fr presented satisfactory psychometric properties. Further studies are needed for identifying predictors of orthorexia as well as improving its definition and assessment.

Validation d’une échelle d’auto-efficacité émotionnelle à transmettre du feedback en contexte de feedback positif et de feedback correctif

Emotional self-efficacy (ESE) is a key construct to understand individual in emotionally charged situations, such as providing performance feedback. However, the existing scale opts for a general vision of the construct. This study therefore aims to validate a specific ESE scale to give feedback in contexts of positive (ESEF+) and corrective (ESEF−) feedback. The data (n = 311) were collected by online questionnaire from a convenience sample. The results of confirmatory factor analyzes show that the two constructs do not have the same structure. For the ESEF−, a seven-factor structure is corroborated, that is, the ESE to perceive, understand and manage one's emotions and those of others, as well as the ESE to use emotions. For the ESEF+, this same structure could not be confirmed. The implications are discussed.     

Belief in luck and luckiness: Conceptual clarification and new measure validation

Research on the dimensionality and measurement of luck beliefs has yet to produce a clear conceptual and metrical consensus. This research theorizes a bidimensional model of luck beliefs that is tested through a series of studies (total n = 1205) validating the new Belief in Luck and Luckiness Scale. Unlike existing conceptualizations and measures, this new model is applicable to both believers and non-believers in luck, and reveals belief in luck and personal luckiness to be discrete, uncorrelated, and respectively unidimensional constructs.     

The development and initial validation of the Fatigue Sensitivity Questionnaire

ABSTRACT

Currently, there is poor understanding of fatigue and the possible psychological conditions that may underlie chronic fatigue. Although substantial work has been directed to better clinically address fatigue, no work has explored individual differences in expectations or perceptions of the negative consequences associated with fatigue-related symptoms. The goals of this study were to (a) develop and (b) validate a measure of expectations or perceptions of the negative consequences associated with fatigue-related symptoms (e.g. fatigue sensitivity) across two independent samples (N = 1,827; 73.1% female; M_age = 21.68; SD = 4.54) of young adults. Results supported a 10-item measure of fatigue sensitivity, entitled the Fatigue Sensitivity Questionnaire (FSQ). The FSQ demonstrated unidimensionality, excellent internal consistency, and strong convergent and discriminant validity. Overall, the 10-item scale offers a single score that can be employed to measure fatigue sensitivity. Clinically, the FSQ may be a brief, informative, and easily disseminated measure in better understanding and capturing expectations or perceptions about the negative consequences of fatigue. As a research tool, the use of the FSQ may provide broader understanding of vulnerability factors that may influence fatigue-related health outcomes. Future research is needed to test the validity of the FSQ in other samples.     

Dyadic coping in Latino couples: validity of the Spanish version of the Dyadic Coping Inventory

Abstract

This study seeks to validate the Spanish version of the Dyadic Coping Inventory (DCI) in a Latino population with data from 113 heterosexual couples. Results for both partners confirm the factorial structure for the Spanish version (Subscales: Stress Communication, Emotion- and Problem-Focused Supportive, Delegated, and Negative Dyadic Coping, Emotion- and Problem-Focused Common Dyadic Coping, and Evaluation of Dyadic Coping; Aggregated Scales: Dyadic Coping by Oneself and by Partner) and support the discriminant validity of its subscales and the concurrent, and criterion validity of the subscales and aggregated scales. These results do not only indicate that the Spanish version of the DCI can be used reliably as a measure of coping in Spanish-speaking Latino couples, but they also suggest that this group relies on dyadic coping frequently and that this type of coping is associated with positive relationship functioning and individual coping. Limitations and implications are discussed.     

Validation francophone de l’inventaire des facilitateurs de l’apprentissage organisationnel (IFAO) : étude comparative de l’apprentissage perçu au niveau des individus,des groupes et de l’organisation

IntroductionThe Inventory of Organizational Learning Facilitator (IOLF) developed by Barrette, Lemyre, Corneil, and Beauregard (2012) is a self-report inventory assessing the presence of certain facilitators of organizational learning within an organizational environment. However, this scale is in English, limiting its applications with francophone populations.ObjectiveThe aim of the study was to create a French version of the Inventory of Organizational Learning Facilitators (IOLF). Furthermore, this study also aimed to verify the metrological qualities as well as the construct validity of the French version of the instrument.MethodThe instrument was translated and verified by expert translators then administered to two distinct samples (francophone and anglophone) each composed of 476 executive's directors working for the federal government's public service. The respondents also completed a three level of perceived learning measures (i.e. individual, group, and organizational).ResultsAnalyses of the factor structure, internal consistency and the pattern of correlations with external variables indicate that the French version converges with the English one.     

Diagnosing organizational cultures: A conceptual and empirical review of culture effectiveness surveys

This review traces the development of survey research methods within the organizational culture tradition and focuses specifically on those instruments that measure the aspects of culture that are related to organizational effectiveness. Our review suggests that the reliability and validity of most instruments in this category is quite limited. This review outlines the recommended logic for the development and validation of culture effectiveness surveys and identifies three key challenges for future culture researchers to address: (1) the confirmatory testing of nested models, (2) the guidelines for aggregating data to the organizational level, and (3) the establishing of criterion-related validity. Using data from the Denison Organizational Culture Survey, we present an empirical illustration of the three challenges identified above and conclude by considering limitations and opportunities for future research.     

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.     

The dimensionality of the Work Related Flow Inventory (WOLF): a South African study

The objective of this study was to validate and explore the factor structure of the Work-Related Flow Inventory (WOLF) as a measure of flow within the South African work context. The sample consisted of N?=?415 employees from various organisations in South Africa (females?=?56.8%, White?=?67.8%, single?=?46%, English?=?34.6%, 18 to 30?=?76.4% and various types of industries and positions). They completed the Work Related Flow Inventory (WOLF), the Utrecht Work Engagement Scale (UWES) and the Job Satisfaction Scale (JSS). Confirmatory factor analysis (CFA) revealed that the WOLF has three dimensions, consisting of absorption, work enjoyment and intrinsic work motivation that fit the data best. The findings further suggest that absorption and work enjoyment relates to work engagement. Convergent validity evidence indicated work absorption, work enjoyment and intrinsic motivation to correlate with both work engagement and job satisfaction in a South African working context. Work enjoyment had the strongest link with job satisfaction.
