Évaluation de la structure factorielle et des qualités psychométriques de l'Échelle de Fatigue Pandémique parmi la population adulte québécoise: Evaluation of the factorial structure and psychometric qualities of the Pandemic Fatigue Scale among Quebec adult population.

OBJECTIVE: The objective of the study is to evaluate the factorial structure and the psychometric qualities of the Pandemic Fatigue Scale among the Quebec adult population. METHOD: The data analyzed come from a web survey conducted in October 2021 among 10 368 adults residing in Quebec. The scale's factor structure and invariance by gender, age and language used to complete the questionnaire were tested using confirmatory factor analyses. Convergent and divergent validity were also assessed. Finally, the reliability of the scale was estimated from the alpha and omega coefficients. RESULTS: The analyzes suggest the presence of a bidimensional structure in the sample of Quebec adults with informational fatigue and behavioral fatigue. The invariance of the measure is noted for sex, for age subgroups and for the language used for the questionnaire. The results of convergent and divergent validity provide additional evidence for the validity of the scale. Finally, the reliability of the scale scores is excellent. CONCLUSION: The results support the presence of a bidimensional structure as in the initial work of Lilleholt et al. They also confirm that the scale has good psychometric qualities and that it can be used among the adult population of Quebec.

A cross-sectional survey on French psychiatrists' knowledge and perceptions of dissociative identity disorder.

OBJECTIVE: The aim of this study was to determine French psychiatrists' level of general knowledge about dissociative identity disorder and to evaluate their perceptions of this condition. METHODS: In this study, French psychiatrists were invited by e-mail to answer an online survey. The questionnaire asked about their general knowledge and perceptions of dissociative identity disorder. RESULTS: We received 924 answers including 582 complete questionnaires. The survey revealed that almost two-thirds (60.8%) of psychiatrists working in France had never received any training on dissociative disorders and 62% had never managed patients suffering from dissociative identity disorder. Only 19.5% of them claimed to believe unreservedly in the existence of the diagnosis of dissociative identity disorder. The psychiatrists' confidence in diagnosing or treating dissociative identity disorder was low (mean confidence in diagnosis: 3.32 out of 10 (SD 1.89), mean confidence in treatment: 3.1 out of 10 (SD 1.68)). Fifty percent believed that dissociative identity disorder is an entity created by cinema, medias or social networks. Seventy-seven point seven percent thought that confusion with borderline personality disorder is possible, and 41.3% with schizophrenia. CONCLUSION: In France, there is a lack of training and knowledge about dissociative identity disorder, as well as persistent skepticism about the validity of the diagnosis. Specific training seems essential for a better understanding of dissociative identity disorder.

Validation of the French COVID-Related Thoughts and Behavioral Symptoms Questionnaire (Cov-Tabs): A self-report assessment.

OBJECTIVES: The COVID-Related Thoughts and Behavioral Symptoms (Cov-Tabs) is a self-reported questionnaire developed to identify the presence of psychological distress and anxiety-related behavior associated with COVID-19. This scale has been used since the first episodes of mass contamination of COVID-19 disease in the USA without psychometric validation analysis. The objective of this paper is to validate the French version of the Cov-TaBS. METHOD: In this study, we assessed a French translation of Cov-Tabs in 300 subjects from the general population. Moreover, we assessed convergent and discriminant validities using an anxiety and depression scale and a paranoid ideation scale. Statistical analyses consisted of evaluating internal consistency, test-retest reliability, and construct validity as well. RESULTS: The French translation of the Cov-Tabs demonstrated high internal consistency and reliability, as well as good temporal stability over a period of less than 2 weeks. It also showed strong convergent validity with anxiety and depression traits and divergent validity with paranoid ideation. CONCLUSION: Our study indicates that the French version of the Cov-Tabs has robust psychometric properties and is a valid tool for evaluating behavioral symptomatology and thoughts related to COVID-19 disease. Therefore, the French version of the Cov-Tabs is a valid tool that can be used in French-speaking individuals.

[A short history of the concept of bias in epidemiology]. / Une brève histoire du concept de biais en épidémiologie.

BACKGROUND: Bias is a major methodological issue for epidemiology. However, only a few studies have been dedicated to the past and present formulations of the concept of bias. Moreover, the classical definition of bias as systematic deviation from the truth of results or inferences, definition which can be found in dictionaries of epidemiology, does not seem to either match the way epidemiologists use it in practice, or correspond to the different definitions given throughout its history. It is consequently important to elucidate this paradox. METHODS: In this historical and conceptual article, we study the different uses of the word "bias" in epidemiological literature, from classic articles in the 1950's about the link between smoking and lung cancer to the most recent epidemiology textbooks, the objective being to analyze the ways in which epidemiologists have defined, applied and modified this concept over time. RESULTS: We show that D.L. Sackett's article on bias in analytic research, published in 1979, put an end, at least temporarily, to reflection in populational epidemiology that started thirty years before. More precisely, we show that Sackett's definition of bias corresponds more to the needs and goals of clinical epidemiology than to those of populational epidemiology. Concomitantly, populational epidemiologists such as K.J. Rothman redefined bias as a threat to the internal validity of a study, and epidemiological study as an "exercise in measurement of an effect rather than as a criterion-guided process for deciding whether an effect is present or not". CONCLUSION: It is thereby important to draw a distinction between two notions pertaining to bias: an epidemiological concept of bias, viewed as the lack of internal validity of an observational study; and a medical concept of bias, defined as deviation from the truth. The former concerns the design and methodology of epidemiological studies; the latter is more general and impels epidemiologists and physicians to be skeptical, and even critical, towards their own inferences.

Validity of the Measure of Intensive Mothering Ideology (MIMI).

OBJECTIVE: The aim of this study was to test the validity of the Measure of Intensive Mothering Ideology (MIMI), a French scale assessing beliefs about mothering and childcare. METHOD: The MIMI was submitted online to Mothers/mothers-to-be (n=249) and Childless women (n=231). To test structural validity, confirmatory factor analyses were conducted in both groups. Then, to test known-groups validity, means comparisons were conducted according to parity (mothers/mothers-to-be and childless women) and employment status (full-time, part-time and housewives). It was also hypothesized that MIMI scores would be negatively correlated with education. RESULTS: Model fit was satisfactory for Mothers/mothers-to-be (X2/df=2.52, AGFI=.957, NFI=.937 RMR=.087) and, to a lesser extent, for Childless women (X2/df=3.31, AGFI=.948, NFI=.907, RMR=.104). In both groups, most dimensions were moderately correlated (.22-.70). As hypothesized, Mothers/mothers-to-be and Housewives had higher score than Childless women and Employed women. MIMI scores were also negatively and moderately correlated with education. CONCLUSION: The MIMI shows good structural validity and known-groups validity. This scale offers interesting research avenues notably regarding perinatal parental adaptation.

Cognitive emotion regulation questionnaire: Psychometric properties of the Tunisian version.

OBJECTIVES: This study investigated the psychometric properties of the Cognitive Emotion Regulation Questionnaire in a Tunisian Arabic-Speaking population. METHOD: The CERQ original version was translated and back-translated and then administrated to 360 participants. Afterwards, using the explanatory and confirmatory factor analysis, we studied the latent factor structure for CERQ. The internal consistency of the subscales was assessed by Cronbach's alfa coefficients, and the test-retest and interscale reliability were assessed with Pearson correlations. The criterion validity was also examined using correlations between the CERQ subscales and both the Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) scales at first evaluation and at a one year follow-up. RESULTS: The Tunisian version was quite satisfactory with the nine-factor structure, as in the original CERQ. Moreover, all validity and reliability measures were comparable to the original CERQ. CONCLUSION: The present study is the first work devoted to a Tunisian adaptation of the CERQ. Our findings highlight that the Tunisian version is both reliable and valid for the measurement of cognitive emotion regulation strategies.

Cross-Cultural Adaptation and Validation of the Quality of Life Questionnaire for Caregivers of Patients with Schizophrenia (S-CGQoL) in Latin America.

OBJECTIVES: The aim of this study was to adapt and validate the Schizophrenia Caregiver's Quality of Life Questionnaire (S-CGQoL) for use in the Hispanic-American population from the caregiver's perspective. METHODS: A cross-sectional instrumental model was used, with a sample of 253 caregivers of patients suffering of Schizophrenia in Bolivia, Peru and Chile. The psychometric properties of the S-CGQoL were tested through construct validity, reliability and some aspects of external validity. In addition, in order to assess the nature of the different items across the three countries, a Differential Performance Analysis (DPA) was conducted. RESULTS: A confirmatory factor analysis showed that the scale structure was well correlated to the initial structure of the QoL-MDS. The results confirmed the existence of adequate reliability indicators (α>.70 and ω>.80) and the absence of FIDs supporting the invariance of item calibrations among the three Latin American countries. CONCLUSIONS: The adaptation and validation of the S-CGQoL questionnaire demonstrate adequate psychometric properties to assess the quality of life of caregivers in samples of middle-income countries in Latin America.

The My Emotions Questionnaire: A self-report of mothers' emotional responses to infant crying.

The purpose of this article was to examine the psychometrics of the My Emotions Questionnaire, a self-report designed to assess mothers' emotional reactions when their infants cry. Participants were 240 first-time mothers. When infants were 6 months and 1 year old, mothers completed the new questionnaire and measures assessing beliefs and behavioral responses to infant crying, and interview-based measures of mothers' emotional reactions and causal attributions about crying were administered. Maternal sensitivity and negative behaviors were observed when infants were 6 months and 1 and 2 years old. Mothers reported on their discipline practices when children were 2 years old. Five emotion factors emerged based on exploratory factor analysis (EFA) of the 6-month data: Amusement, Anxiety, Frustration, Sympathy, and Protective. The five-factor structure was supported via a confirmatory factor analysis (CFA) of the 1-year data. All scales demonstrated adequate internal consistency reliability and significant stability from 6 months to 1 year. Amusement, Frustration, and Protectiveness demonstrated the best convergent validity with cry cognitions and predictive validity to parenting measures, followed by Anxiety, although effects tended to be small to moderate. Evidence for the validity of Sympathy was less compelling. The potential utility of the questionnaire for basic and applied research is discussed.

El propósito de este ensayo fue examinar la sicometría del Cuestionario Mis Emociones, un auto-reporte diseñado para evaluar las reacciones emocionales de las madres cuando sus infantes lloran. Las participantes fueron 240 madres primerizas. Cuando los infantes tenían 6 meses y 1 año de edad, las madres completaron el nuevo cuestionario y se les administraron medidas para evaluar creencias y la conducta de respuesta al llanto del infante, así como medidas basadas en entrevistas sobre las reacciones emocionales de las madres y atribuciones causales acerca del llanto. Cuando los infantes tenían 6 meses, 1 año y 2 años, se observaron la sensibilidad materna y las conductas negativas. Las madres reportaron acerca de sus prácticas disciplinarias cuando los niños tenían 2 años. Cinco factores de emoción surgieron de la información a los 6 meses, con base en los análisis exploratorios de factores: diversión, ansiedad, frustración, simpatía y actitud de protección. La estructura de cinco factores fue apoyada por medio de un análisis confirmatorio de factores de la información de 1 año. Todas las escalas demostraron una confiabilidad adecuada de consistencia interna y significativa estabilidad desde los 6 meses hasta 1 año. La diversión, la frustración y la actitud de protección demostraron la mejor validez convergente con conocimientos del llanto y validez predictiva hacia las medidas de crianza, y fueron seguidas por la ansiedad, aunque los efectos tendieron a ser entre pequeños y moderados. La evidencia por la validez de la simpatía fue menos convincente. Se discute la posible utilidad del cuestionario para la investigación básica y aplicada.

Le but de cet article était d'examiner la psychométrie du Questionnaire Mes Emotions, une auto-évaluation conçue pour évaluer les réactions émotionnelles des mères lorsque leurs bébés pleurent. Les participantes étaient 240 mères pour la première fois. Lorsque les bébés avaient 6 mois et 1 an, les mères ont rempli le nouveau questionnaire et les mesures évaluant les croyances et les réactions comportementales aux pleurs du bébé et des mesures basées sur des entretiens de réactions émotionnelles des mères et les attributions causales sur les pleurs ont été administrées. La sensibilité maternelle et les comportements négatifs ont été observés lorsque les enfants avaient 6 mois, 1 an, 2 ans. Les mères ont fait état de leurs disciplinaires quand les enfants avaient 2 ans. Cinq facteurs d'émotion ont émergé, basé sur l'analyse des facteurs exploratoires des données de 6 mois : amusement, anxiété, frustration, sympathie et protectrice. La structure de 5 facteurs a été soutenue au travers d'une analyse des facteurs de confirmation des données d'une année. Toutes les échelles ont démontré une fiabilité adéquate de la cohérence interne et une stabilité importante de 6 mois à 1 an. L'amusement, la frustration et la protection ont démontré la meilleure validité convergente avec les cognitions des pleurs et la validité prédictive aux mesures de parentages suivies par de l'anxiété, bien que les effets avaient tendance à être petits à modérés. Les preuves de la validité de la sympathie étaient moins convaincantes. L'utilité potentiel du questionnaire pour les recherches de base et les recherches appliquées sont discutées.

Validity and reliability of methods to microscopically detect and quantify malaria parasitaemia.

OBJECTIVES: The recommended microscopy method by WHO to quantify malaria parasitaemia yields inaccurate results when individual leucocyte (WBC) counts deviate from 8000 leucocytes/µl. A method avoiding WBC count assumptions is the Lambaréné method (LAMBA). Thus, this study compared validity and reliability of the LAMBA and the WHO method. METHODS: Three methods for counting parasitaemia were applied in parallel in a blinded assessment: the LAMBA, the WHO method using a standard factor of 8000 leucocytes/µl ['simple WHO method' (sWHO)] and the WHO method using measured WBC counts ['accurate WHO method' (aWHO)]. Validity was assessed by comparing LAMBA and sWHO to the gold standard measurement of aWHO. Reliability was ascertained by computation of intraclass correlation coefficients (ICCs). RESULTS: 787 malaria-positive thick smears were analysed. Parasitaemia as determined by LAMBA and sWHO increasingly deviated from aWHO the more patients' WBCs diverged from 8000/µl. Equations of linear regression models assessing method deviation in percent from gold standard as function of WBC count were y = -0.00608x (95% CI -0.00693 to -0.00524) + 47.8 for LAMBA and y = -0.0125x (95% CI -0.01253 to -0.01247) + 100.1 for sWHO. Comparison of regression slopes showed that the deviation was twice as high for sWHO as for LAMBA (P < 0.001). ICCs were excellent (>90%) for both methods. CONCLUSIONS: The LAMBA has higher validity than the sWHO and may therefore be preferable in resource-limited settings without access to routine WBC-evaluation.

Psychometric properties of the Resilience Scale - 14 in a sample of college students from France.

INTRODUCTION: In recent years, the integration of resilience in several psychological and medical studies underscores a need for resilience assessment measures with robust psychometric properties. This study aimed to evaluate the underlying structure of the French version of the Resilience Scale (RS-14), a widely used measure to assess resilience both in general and clinical population. METHOD: A sample of 2195 college students from France (18.68% of male; Mean age=20.09 years old (±1.21) completed the RS-14, the Child and Youth Resilience Measure, the Social Support Questionnaire and the Kessler Psychological Distress Scale. EFA with parallel analysis was conducted to assess the factorial structure of the RS-14 while CFA was performed to investigate the goodness-of-fit. Internal consistency, concurrent and convergent validity were evaluated. RESULTS: A one-dimensional-factorial-solution emerged from the EFA, its goodness-of-fit was adequate and it presented good internal consistency. As expected, the RS-14 score correlated positively to the CYRM and SSQ scores and negatively to the psychological distress score, supporting the validity of the scale. CONCLUSION: The one-dimensional-factor corroborates the initial and many languages versions of the RS-14. The results showed that the French version of the RS-14 presents adequate psychometric properties and that is a reliable and valid scale in evaluating resilience.

Psychometric properties of the French version of a scale measuring perceived emotional intelligence : the Trait Meta-Mood Scale (TMMS).

OBJECTIVE: The Trait Meta-Mood Scale (TMMS), a 30-item self-assessment questionnaire, has been developed to measure perceived emotional intelligence (EI) level in 3 dimensions: Attention, Clarity and Repair. This study aimed to explore the psychometric properties of the French version of this instrument. METHOD: The instrument factor structure, normality, internal consistency, stability and concurrent validity were assessed in a sample of 824 young adults (456 female). Besides TMMS, participants completed self-assessment questionnaires for affectivity (Shortened Beck Depression Inventory, State and Trait Anxiety Inventory, Positive and Negative emotion scale), alexithymia (Bermond-Vorst Alexithymia Questionnaire-B) and interpersonal functioning (Empathy Quotient). Discriminant validity was tested in 64 female patients with anorexia nervosa, identified in literature as having difficulties with introspection, expression and emotional regulation. RESULTS: Confirmatory factor analysis results replicate the 3-factor structure. Internal consistency and reliability indices are adequate. Direction and degree of correlation coefficients between TMMS dimensions and other questionnaires support the instrument concurrent validity. TMMS allows to highlight differences in perceived EI levels between men and women (Attention: p < 0.001 ; Clarity: p < 0.05) as well as between patients with anorexia nervosa and control subjects (p < 0.001 for all 3 dimensions). CONCLUSION: This first validation study shows satisfying psychometric properties for TMMS French version.

[How may practitioners interpret the results of clinical trials?] / Comment le praticien doit-il interpréter les résultats d'un essai clinique ?

To correctly interpret the results of a randomised controlled trial (RCT), practitioners have to spot bias and other potential problems present in the trial. Internal as well as external validity of the trial are linked to the presence of such bias. The internal validity is ensured by a clear definition of the objectives of the trial. The number of patients to be included in the trial is calculated on the basis of the main objective of the trial and more precisely on the basis of the primary endpoint selected to assess the efficacy of treatment. This is the best way to ensure that the statistical significance of the result may have a clinical relevance. Internal validity depends also on the process of patients selection, the methods used to ensure comparability of groups and treatments, the criteria employed to assess efficacy, and the methods for the analysis of data. External validity refers to subjects that have been excluded from the trial, limitations of RCTs, as well as the coherence and clinical relevance of the trial. Internal validity has to be fueled by external validity.

[Translation and validation of the Life Balance Inventory: An occupational therapy questionnaire]. / Traduction et validation du questionnaire ergothérapique l'Inventaire de l'équilibre de vie

BACKGROUND: Despite the interest in the concept of life balance, no questionnaire is currently available in French to measure it well. PURPOSE: This study aimed to translate the Life Balance Inventory (Objective 1) and to verify the convergent validity of the French version (Objective 2). METHOD: A cross-cultural validation was first carried out, followed by a cross-sectional descriptive study, with 152 adults ages 40 and over, with and without physical disabilities. Questionnaires were used to measure the following variables, life balance, stress, health, and quality of life. RESULTS: A better life balance is associated with a lower degree of stress (r = -.36; p < .01) as well as higher physical health (r = .42; p = .01), mental health (r = .36; p = .01), and quality of life (r = .54; p < .01). IMPLICATIONS: The French version of the Life Balance Inventory is a valid questionnaire to assist occupational therapists when assessing time use of their clients.

THE SURVEY OF WELL-BEING OF YOUNG CHILDREN: RESULTS OF A FEASIBILITY STUDY WITH AMERICAN INDIAN AND ALASKA NATIVE COMMUNITIES.

This study examined the feasibility of the Survey of Well-Being of Young Children (SWYC), a new screener for socioemotional and developmental problems and family risk in children birth to age 5 years, for use in American Indian and Alaska Native (AIAN) communities. A Community of Learning within the Tribal Early Childhood Research Center, composed of university researchers, tribal early childhood program staff and evaluators, and federal partners, utilized a community-based participatory research approach to guide this qualitative study. Thirty-two focus groups and 20 key informant interviews (N = 199) were conducted with staff from Head Start, Home Visiting, and Child Care programs; pediatricians; behavioral health providers; parents of young children; tribal leaders; and other stakeholders in seven diverse AIAN communities. Three themes emerged: (a) a strong need to screen early for socioemotional and developmental problems and family risk; (b) the importance of a carefully designed process for screening; and (c) the importance of examining the content of the SWYC for cultural fit specific to tribal communities. Findings support two recommendations: (a) the development of guidelines for using the SWYC in tribal early childhood settings and (b) a full-scale validation study to determine appropriate use with and norms for children in tribal communities.

Development and Validation of a Self-Care Ability Measure.

Self-care is an outcome of nursing care that is instrumental for promoting recovery and preventing complications following hospitalization. The Therapeutic Self-Care (TSC) measure was developed to assess self-care ability in acute-care settings. Its content was derived from a conceptualization of selfcare generated from an extensive literature review. Clinical experts considered the 13 items of the TSC measure as relevant, supporting its content validity. Findings of 1 study indicate that the items are internally consistent and loaded on 1 factor. The TSC scores correlate with relevant concepts. The TSC measure quantifies patients' perceived ability for self-care, operationalized in behaviours related to taking medications, recognizing and managing symptoms, carrying out activities of daily living, and managing changes in condition. It can be used to guide and evaluate nursing care.

L'autogestion des soins est un résultat de soins infirmiers déterminant pour le rétablissement du patient et la prévention des complications après une hospitalisation. Dans le but d'évaluer la capacité d'autogestion dans un contexte de soins actifs, nous avons élaboré un instrument de mesure appelé Therapeutic Self-Care (TSC). Son contenu est dérivé d'une conceptualisation de l'autogestion fondée sur une vaste synthèse de la recherche sur le sujet. Des experts cliniques ont confirmé la pertinence de ses 13 items et corroboré la validité de son contenu. Une étude a montré que les items ont une cohérence interne et sont représentés par un seul facteur. Les scores corrèlent avec les concepts pertinents. L'instrument quantifie la capacité d'autogestion des soins telle que perçue par le patient, opérationnalisée notamment dans les comportements touchant la prise des médicaments, la reconnaissance des symptômes et leur gestion, l'exécution des activités de la vie quotidienne et la modification de l'état de santé. Il peut servir à guider la prestation des soins infirmiers et à évaluer celle-ci.

Comparative Analysis of External Validity Reporting in Non-randomized Intervention Studies.

This article describes a comparative analysis of external validity reporting in non-randomized behavioural and public health intervention studies that used and did not use the TREND (Transparent Reporting of Evaluations with Non-randomized Designs) statement. The search resulted in 14 non-randomized intervention studies that were rated based on Green and Glasgow's criteria for external validity reporting. Studies that used the TREND statement demonstrated improved external validity reporting when compared with studies that did not use the TREND statement. The implication is that the TREND statement and Green and Glasgow's criteria can improve external validity reporting of non-randomized behavioural and public health interventions.

Cet article présente une analyse comparative d'établissements de rapports de validité externe dans le cadre d'études d'interventions non aléatoires en matière de comportements et de santé publique faisant usage et ne faisant pas usage de l'énoncé TREND (Transparent Reporting of Evaluations with Non-randomized Designs). La recherche a relevé 14 études d'interventions non aléatoires, lesquelles ont été évaluées selon les critères de Green et Glasgow quant à l'établissement de rapports de validité externe. Les études ayant utilisé l'énoncé TREND ont démontré la présence de rapports de validité externe améliorés, en comparaison avec les études n'ayant pas fait usage de l'énoncé TREND. En conclusion, l'énoncé TREND et les critères de Green et Glasgow peuvent améliorer les rapports de validité externe d'interventions non aléatoires en matière de comportements et de santé publique.

The Canadian Hypoglycemia During Hospitalization Score Is Externally Valid in the Australian Diabetes IN-hospital: Glucose & Outcomes (DINGO) Cohort.

OBJECTIVES: The Hypoglycemia During Hospitalization (HyDHo) score predicts hypoglycemia in a population of Canadian inpatients by assigning various weightings to 5 key clinical criteria known at the time of admission, in particular age, recent presentation to an emergency department, insulin use, use of oral hypoglycemic agents, and chronic kidney disease. Our aim in this study was to externally validate the HyDHo score by applying this risk calculator to an Australian population of inpatients with diabetes. METHODS: This study was a retrospective data analysis of a subset of the Diabetes IN-hospital: Glucose & Outcomes (DINGO) cohort. The HyDHo score was applied based on clinical information known at the time of admission to stratify risk of inpatient hypoglycemia. RESULTS: The HyDHo score was applied to 1,015 patients, generating a receiver-operating characteristic c-statistic of 0.607. A threshold of ≥9, as per the original study, generated a sensitivity of 83% and a specificity of 20%. A threshold of ≥10, to better suit this Australian population, generated a sensitivity of 90% and a specificity of 34%. The HyDHo score has been externally valid in a geographically different population; in fact, it outperformed the original study after accounting for local hypoglycemia rates. CONCLUSIONS: Our findings support the external validity of the HyDHo score in a geographically different population. Application of this simple and accessible tool can serve as an adjunct to predict an inpatient's risk of hypoglycemia and guide more appropriate glucose monitoring and diabetes management.

[Psychometric properties of the French version of the How I Think Questionnaire]. / Étude des qualités psychométriques de la version française du How I Think Questionnaire dans un échantillon d'adolescents français.

UNLABELLED: Certain research has pointed out the relative importance of cognitive distortions in the development of antisocial behavior. Distortions of social cognitions that facilitate aggression and other types of antisocial behavior have been described as self-serving cognitive distortions (Barriga et al., 2001 [2]). Considering the importance of the assessment of delinquent cognitive distortions, an instrument has been validated to measure self-serving cognitive distortions: the How I Think Questionnaire (HIT-Q, Barriga et al., 2001 [2]). Thus, the aim of the present study was to evaluate the convergent, discriminant and concurrent validity of a French version of the HIT-Q and its four dimensions (self-centered, blaming other, minimizing/mislabeling and assuming the worst). METHOD: A sample of 972 French high-school students completed the Youth Psychopathic traits Inventory (YPI ; Andershed et al., 2002 ; Andershed et al., 2007 [26,27]) used to evaluate the convergent validity of the HIT-Q. To investigate discriminant validity, participants also completed the Sociomoral Reflection Measure-Short Form (SMR-SF ; Gibbs et al., 1992 [28]) and the Interpersonal Reactivity Index (IRI ; Davis, 1983 [29]) used to assess cognitive and affective empathy. To measure antisocial behavior, the French versions of the Self-Reported Delinquency Questionnaire (SRDQ ; Le Blanc and Frechette, 1989 [22]), the Antisocial Behavior Scale (ABS ; Schawb-Stone et al., 1996 [23]), the Self-Reported Delinquency Behavior (SRDB ; Elliott and Menard, 1996 [24]) and three items of the Sexual Experiences Survey (SES ; Koss et al., 2007 [25]) were used. Two samples were composed based on the same socio-demographic (age and gender) and socio-economic characteristics and ethnic background. French males scoring in the upper quartile on the antisocial behavior total score were classified in the antisocial group (n=135) and the rest of the sample in the non-antisocial group (n=306). Convergent and discriminant validity was determined using Pearson coefficients of correlation. One-way analyses of variance were used for mean scores comparisons. Regression analysis was used to evaluate the relative contribution of self-serving cognitive distortions to the prediction of antisocial behavior. RESULTS: The French version of the HIT-Q showed acceptable reliability and validity and also a satisfying convergent and discriminant validity. The HIT-Q and its dimensions were positively and highly correlated to psychopathic traits (r=0.50 to r=0.61, p<0.05) ; these findings suggested a good convergent validity. The correlation between self-serving cognitive distortions and social moral reasoning (r=-0.23 to r=-0.28, p<0.05) and empathy (r=-0.13 to r=-0.20, p<0.05) appeared to be negative and low ; this relationship was conclusive and showed a satisfying discriminant validity. Mean comparison showed that participants in the antisocial group reported higher scores of self-serving cognitive distortions and its dimensions than the non-antisocial group. Self-serving cognitive distortions significantly predicted antisocial behavior (ß=0.58, SE=0.02, p<0.001) and explained 34% of the variance. DISCUSSION: The study of the convergent validity of the HIT-Q with the YPI as external criteria showed they were closely linked, which suggests self-serving cognitive distortion may be the cognitive expression of psychopathic traits. The discriminant validity of the HIT-Q with moral reasoning and empathy was satisfying and similar to previous results (Lardén et al., 2006 [20]). In concordance with previous studies, delinquent cognitive distortions appeared to be a significant predictor of antisocial behavior and moreover, participants in the antisocial group reported higher scores of self-serving cognitive distortions (Capuano, 2007 ; Barriga and Gibbs, 1996 ; Nas et al., 2008 [10-12]). CONCLUSION: The present study showed that the French version of the HIT-Q presents good psychometric properties.

Validity and reliability of a portable handheld dynamometer compared to a fixed isokinetic dynamometer to assess forearm torque strength.

To evaluate the effect of treatment on forearm rotation, torque muscle strength can be assessed using an isokinetic device (IKD) or a wrist dynamometer (WD). The aims of this study were 1) to determine concurrent validity and intra- and inter-rater reliability using the WD, and to examine correlations between WD and IKD in different positions; and 2) subsequently, to establish the intermethod reproducibility between WD as a handheld (HHD) or fixed device. We conducted a cross-sectional study in which torque strength was measured in healthy participants by two observers using an IKD and a WD. Study endpoints were concurrent validity (Pearson's r), intra- and inter-rater reliability, intermethod reproducibility (intraclass correlation coefficient: ICC) and measurement error (limits of agreement: LoA). Concurrent validity ranged, in the 2 studies assessing it, from r 0.37 to 0.52 for pronation and from r 0.50 to 0.82 for supination, with wide 95% confidence intervals. ICC for intra-rater reliability for pronation ranged from 0.85 to 0.91 and for supination from 0.91 to 0.95. ICC for inter-rater reliability for pronation ranged from 0.84 to 0.96 and for supination from 0.92 to 0.96. Despite the excellent intra- and inter-rater reliability and intermethod reproducibility for the WD-HHD and fixed WD, validity was low when compared to IKD and wide LoA indicated a high measurement error of approximately 20%. These results suggest that the WD cannot replace the IKD isometric mode for pronation and supination. LEVEL OF EVIDENCE: 2.

Validity and Accuracy of the Tilburg Frailty Indicator Part B for Identification of Frailty in Older Adults Consulting a Rural Geriatric Medicine Clinic.

The Tilburg Frailty Indicator (TFI) is a validated tool for determining frailty in older adults. This study examined the validity and accuracy of the TFI Part B (TFI-B) in a North American context. Seventy-two individuals ≥ 65 years of age recruited from a rural geriatric medicine clinic completed a set of self-reported and performance-based measures, including TFI-B. Frailty level was determined using modified Fried's Frailty Phenotype (FFP). Pearson correlation coefficients (r) assessed the concurrent relationships between the TFI-B and other measures. Accuracy of the TFI-B in classifying frailty level was assessed using assessing area under the curve (AUC). The TFI-B scores showed low correlations (r < 0.4) with gait speed and grip, suggesting that the TFI-B did not consider frailty as merely a physical problem. The AUC of 0.82 indicated that the TFI-B scores accurately classified frail versus non-frail individuals. The score of ≥ 5 on the TFI-B scores showed satisfactory sensitivity/specificity (73%/77%) and excellent negative predictive value (91.95%). This indicates that a TFI-B score of < 5 can be used to rule out frailty.
