Validation de l'adaptation française de l'échelle de dépendance à l'exercice physique : l'EDS-R

The research purpose is to examine the internal consistency, test–retest reliability and factorial validity of the Exercise Dependence Scale-Revised (EDS-R), translate into French language. Three studies, containing 965 persons, are undertaken to accomplish these purpose. Participants have completed the EDS-R. Adequate internal consistency and test–retest reliability for the scale are evidenced in the two first studies. Confirmatory analysis (Lisrel) in study 3 supported a correlated seven-factor model, the model fit are acceptable (TLI = 0,93; CFI = 0,94; RMSEA = 0,062; SRMR = 0,06). These studies provide evidence for the reliability and validity of the EDS-R into French. Language. This instrument can be thus used in the clinical and studies framework on the exercise dependence.     

Using Personality Item Characteristics to Predict Single‐Item Internal Reliability,Retest Reliability,and Self–Other Agreement

The use of reliability estimates is increasingly scrutinized as scholars become more aware that test–retest stability and self–other agreement provide a better approximation of the theoretical and practical usefulness of an instrument than its internal reliability. In this study, we investigate item characteristics that potentially impact single‐item internal reliability, retest reliability, and self–other agreement. Across two large samples (N = 6690 and N = 4396), two countries (Estonia and The Netherlands), and two personality inventories (the NEO PI‐3 and the HEXACO‐PI‐R), results show that (i) item variance is a strong predictor of self–other agreement and retest reliability but not of single‐item internal reliability; (ii) item variance mediates the relations between evaluativeness and self–other agreement; and (iii) self–other agreement is predicted by observability and item domain. On the whole, weak relations between item length, negations, and item position (indicating effects of questionnaire length) on the one hand, and single‐item internal reliability, retest reliability, and self–other agreement on the other, were observed. In order to increase the predictive validity of personality scales, our findings suggest that during the construction of questionnaire items, researchers are advised to pay close attention especially to item variance, but also to evaluativeness and observability.

Psychometric properties of the French version of Brief Sensation Seeking Scale (B-SSS)

IntroductionA French version of the Briefing-Sensation Seeking Scale (B-SSS) (Hoyle et al., 2002) was developed according to a process of double reverse translation.ObjectiveTwo studies were then led to validate the psychometrics properties (validity and the reliability) of this French version of the B-SSS.MethodsIn the first study, 97 participants (14–24 years old) answered the original version (in English) and the translated version (in French). In the second study, 124 participants (14–24 years) answered the French version at two times measurement. Psychometrics analyses brings together reliability indices (Cronbach's alpha and temporal stability) and concurrent validity indices.ResultsFor both studies, Cronbach alphas were used to assess internal consistency, while intraclass coefficients (ICC) demonstrated temporal stability. In the second study, Pearson correlations between the French version and the ImpSS supported concurrent validity. Reliability is acceptable in the first study (α = .601 in, 674; ICC = .550–.895) and satisfactory in the second study (α = .734–.755; ICC = .650–.948). Pearson's correlation of the French version of the B-SSS and the ImpSS varies between .658 and .754.ConclusionPsychometrics properties of the French version of the B-SSS show that this scale can be used to measure sensation seeking with teenagers and for young adults.     

HEXACO personality and Schwartz's personal values: A facet-level analysis

This study systematically examined the correlates of Schwartz’s basic values with the broad and narrow traits of the HEXACO model of personality. A sample of 1244 adults (53% male; M age = 44, SD = 12) completed the 200-item HEXACO-PI-R and the Portrait Values Questionnaire measuring Schwartz’s 10 basic personal values. Regression models predicting each of the ten basic values from personality revealed mean-adjusted multiple correlations of .39 for HEXACO factors without honesty-humility, .45 for all HEXACO factors, and .53 for HEXACO facets. The facet-level multiple correlations were particularly large (>.60) for power, universalism, and cooperation. Results suggest that individual differences in personality and values overlap to a greater extent than implied by past literature.     

On the assessment of the test–retest of Riding’s CSA: A commentary on Peterson,Deary, and Austin

Peterson, Deary, and Austin (2003) considered the reliability of the Cognitive Styles Analysis (CSA) (Riding, 1991). The CSA seeks to assess an individual’s position on each of two fundamental style dimensions – the Wholist-Analytic and the Verbal-Imagery dimensions. It presents a series of simple cognitive tasks, which the subjects may choose to process according to their preferred style. Performance on these test items is in terms of response times. The CSA comprises 40 items to assess the Wholist-Analytic and 48 for the Verbal-Imagery and typically takes 15–20 min to complete. It is intended to be suitable for a wide age and ability range, and applicable to a variety of contexts and cultures.The most important characteristic of any test of cognitive style is its temporal stability. Studies which attempt to establish test validity without definitive evidence of test reliability are lacking a basic foundation. Riding has not published any statistical data on the test–retest reliability of the CSA.Peterson et al. (2003) and Peterson (2003) claim to have carried out the primary evaluation of the CSA’s reliability. However we were the first to publish accurate test–retest reliability data on Riding’s CSA (Redmond, Mullally, & Parkinson, 2002).This brief report addresses the issue as to who initially established the unreliability of the CSA in the first place and why Peterson, Deary and Austin’s claims are misleading and unsubstantiated.     

Personality and substance use in Japanese adolescents: The Japanese version of Substance Use Risk Profile Scale

Substance Use Risk Profile Scale (SURPS; Conrod & Woicik, 2002) measures four risk personality dimensions related to substance use; anxiety sensitivity (AS), hopelessness (H), sensation seeking (SS), impulsivity (IMP). The aim of this study is to develop the Japanese version of Substance Use Risk Profile Scale (SURPS-J) and to probe the reliability and validity of this scale to the Japanese context. This study consists of the test of the factor analysis (Study 1; N = 462), the reliability (Study 2; N = 64), and the validity (Study 3; N = 182). Our findings are as below; Study 1 showed the conformed factorial structure of SURPS-J and Study 2 revealed the good test–retest reliability. Additionally, Study 3 demonstrated the adequate validity of SURPS-J and its sensitivity in identifying risky drinking motivations and lifetime tobacco and alcohol use. Results showed that high H individuals are likely to experience smoking under the personal and collective situations, while high SS and IMP individuals are prone to drink alcohol under the collective situation. Additionally, high AS individuals are prone to drink by virtue of negative reinforcement motives and high SS and IMP drink by reason of all drinking reinforcement motives.     

Development and initial assessment of a short measure for adult playfulness: The SMAP

This study reports an initial evaluation of a new short measure for adult playfulness (SMAP). In data from a construction (N = 266), and two replication samples (N = 147 students, N = 215 adults), a one-dimensional solution showed the best fit for the data and satisfactory internal consistency (.80–.89) was found (test–retest correlation = .74; 12–16 weeks). Younger adults scored higher in playfulness than older ones. The SMAP demonstrated robust correlations with measures for adult playfulness and the need for play. Cheerfulness and culture along with low seriousness and low conscientiousness were its best predictors. In ratings of an unordered work-space and a surrealistic painting, playful adults expressed higher liking for and lower disapproval of these compared to non-playful adults. Overall, the new scale yielded good psychometric properties and first evidence on its validity was encouraging. The SMAP has been developed for an economic, global assessment of adult playfulness, which is still an understudied topic in personality research.     

Development and validation of the Body and Appearance Self-Conscious Emotions Scale (BASES)

The purpose of these studies was to develop a psychometrically sound measure of shame, guilt, authentic pride, and hubristic pride for use in body and appearance contexts. In Study 1, 41 potential items were developed and assessed for item quality and comprehension. In Study 2, a panel of experts (N = 8; M = 11, SD = 6.5 years of experience) reviewed the scale and items for evidence of content validity. Participants in Study 3 (n = 135 males, n = 300 females) completed the BASES and various body image, personality, and emotion scales. A separate sample (n = 155; 35.5% male) in Study 3 completed the BASES twice using a two-week time interval. The BASES subscale scores demonstrated evidence for internal consistency, item-total correlations, concurrent, convergent, incremental, and discriminant validity, and 2-week test–retest reliability. The 4-factor solution was a good fit in confirmatory factor analysis, reflecting body-related shame, guilt, authentic and hubristic pride subscales of the BASES. The development and validation of the BASES may help advance body image and self-conscious emotion research by providing a foundation to examine the unique antecedents and outcomes of these specific emotional experiences.     

Children’s social desirability: Effects of test assessment mode

This study examined a recently developed short version of the Children’s Social Desirability (CSD-S) scale with 157 fourth-grade children. Of interest was (a) whether one-month test–retest reliability would vary as a function of test assessment mode (interview or classroom), gender, race, SES, and BMI percentile, and (b) whether the degree of social desirability would vary as a function of these same variables. The CSD-S scale showed good test–retest reliability for both interview and classroom assessment modes (.85 and .83, respectively). Internal consistency also was good (first interview administration = .84; first classroom administration = .81). Reliability was good and did not vary significantly over assessment mode or any child subgroup variables, suggesting that the CSD-S scale is appropriate for general use. The interview mode elicited significantly more socially desirable answers than did the classroom mode. Social desirability did not differ across child subgroups. Some of these findings were examined, and replicated, on another sample. Thus, the CSD-S scale may be used with diverse groups of children to (a) reliably assess a social desirability bias that may systematically bias other self-reports of interest to researchers and (b) examine individual differences in degree of social desirability.     

A comparison of self-other agreement in personal values versus the Big Five personality traits

Can we judge other people’s values accurately, or are values too subjective to assess? We compared self-other agreement in personal values with agreement in the Big Five personality traits. Self-other agreement in four higher-order values (median r = .47) and in six culture-specific value factors (median r = .50) was substantial and similar to that for the Big Five personality traits (median r = .51). When corrected for attenuation due to measurement error self-other agreement was high for all three scales (median rs > .65). The results suggest that people can assess values of others whom they know well with remarkable accuracy. Therefore, other-ratings of personal values can be used to validate and complement self-report value measures.     

Individual differences in neural regions functionally related to real and imagined stuttering

Recent brain imaging investigations of developmental stuttering show considerable disagreement regarding which regions are related to stuttering. These divergent findings have been mainly derived from group studies. To investigate functional neurophysiology with improved precision, an individual-participant approach (N = 4) using event-related functional magnetic resonance imaging and test–retest reliability measures was performed while participants produced fluent and stuttered single words during two separate occasions. A parallel investigation required participants to imagine stuttering or not stuttering on single words. The overt and covert production tasks produced considerable within-subject agreement of activated voxels across occasions, but little within-subject agreement between overt and covert task activations. However, across-subject agreement for regions activated by the overt and covert tasks was minimal. These results suggest that reliable effects of stuttering are participant-specific, an implication that might correspond to individual differences in stuttering severity and functional compensation due to related structural abnormalities.     

Body Shape Questionnaire: Psychometric properties of the short version (BSQ-8C) and norms from the general Swedish population

There is a need for brief, sensitive, and reliable instruments for contextual assessment of body dissatisfaction. Suitable selection and optimal use of psychological assessment instruments requires appropriate psychometric as well as normative data. Two studies were conducted to investigate the psychometric properties and collect general population norms for a short, eight item version of the Body Shape Questionnaire (BSQ-8C). In the first study, a sample of undergraduate students (N = 182) was recruited to investigate the psychometric properties of the BSQ-8C, while in the second study a sample from the general population of Swedish women aged 18–30 years (N = 747) was used to collect norms. The test–retest reliability, internal consistency, and convergent validity for BSQ-8C were high. Given the questionnaire's briefness and good psychometric properties, particularly when used in conjunction with norms, the BSQ-8C is considered a valuable instrument for measuring body shape dissatisfaction among young adult women.     

Trait anxiety and trait anger measured by ecological momentary assessment and their correspondence with traditional trait questionnaires

Ecological momentary assessments (EMA) of anxiety and anger/hostility were obtained every 25–30 min over two 24-h periods, separated by a median of 6 months, from 165 employees at a university in the Northeast. We used a multilevel trait-state-error structural equation model to estimate: (1) the proportion of variance in EMA anxiety and anger/hostility attributable to stable trait-like individual differences; (2) the correspondence between these trait-like components of EMA anxiety and anger/hostility and traditional questionnaire measures of each construct; and (3) the test–retest correlation between two 24-h averages obtained several months apart. After adjustment for measurement error, more than half the total variance in EMA reports of anxiety and anger/hostility is attributable to stable trait-like individual differences; however, the trait-like component of each construct is only modestly correlated with questionnaire measures of that construct. The 6-month “test–retest” correlations of latent variables representing the true 24-h EMA average anxiety and average anger are quite high (r ? 0.83). This study represents the longest follow-up period over which EMA-based estimates of traits have been examined. The results suggest that although the trait component (individual differences) of EMA momentary ratings of anxiety and anger is larger than the state component, traditional self-report questionnaires of trait anxiety and anger correspond only weakly with EMA-defined traits.     

Comparison of fetal and maternal heart rate measures using electrocardiographic and cardiotocographic methods

PurposeTo determine the reliability at term of: (1) two methods of measuring fetal heart rate (HR), electrocardiographic (ECG, the ‘gold standard’) and cardiotocographic (CTG) and (2) two ECG methods of measuring maternal HR variability over relatively brief periods of time (s–min).MethodsDuring 20 min of rest (N = 39) and during 2 min of auditory stimulation (mother's recorded voice, n = 19), fetal HR data were collected using an ECG (Monica AN24) and a Hewlett-Packard Model 1351A CTG. Simultaneously, maternal HR data (n = 37) were collected using the same ECG device (Monica AN24) and a second stand-alone cardiac monitor (Spacelab 514T cardiac monitor with a QRS detector).ResultsDuring 20 min of maternal rest, correlations of individual fetal CTG with ECG measures of HR at each second were moderate to high (r = .57–.97) for 77% of fetuses. Correlations of HR averaged over fetuses and over each of the 20 min were high (r = .93–.97); fetal HR averaged over 20 min varied between devices from 0.0 to 0.8 bpm. During 2 min of maternal voice presentation, correlations of fetal HR over each second were moderate to high (r = .54–.99) for 95% of fetuses and high (all rs = .99) when averaged across fetuses in 30 s or 2 min epochs. Average fetal HR between devices over the 2 min voice varied from 0.0 to 0.6 bpm. Correlations and/or % agreement between the two ECG methods of measuring maternal HR were high. Average maternal HR over 10 min showed 81% of pairs with a difference of ≤1 bpm; correlations for HR variability measures varied from r = .89 to .97.ConclusionsGood reliability was demonstrated between individual spontaneous and auditory induced fetal CTG and ECG with high correlations when HR data were averaged over fetuses or in 30–120 s epochs. High reliability of maternal HR measures was obtained using two ECG devices.     

Mesure de la balance décisionnelle en vue de pratiquer une activité physique régulière (BDAP) : adaptation et validation francophone de l’échelle Decisional Balance for Exercise

ObjectiveThe purpose of this study was to validate a French version of the Decisional Balance Scale for Exercise (BDAP) and to examine its psychometric properties as well as its relationship with the three other components of Transtheoritical Model (TTM).Participants and methodFour hundred and six subjects (270 women), aged between 16 to 65 years old, fulfilled BDAP and other questionnaires measuring the three other components of TTM (Stages of Change of Exercise Behavior Scale, Exercise Processes of Change Questionnaire, Exercise Confidence Survey).ResultsConfirmatory factor analyses supported the two-factor model of BDAP (pros, α = 0.85 and cons, α = 0.73) assumed in the MTT. A good test–retest reliability was observed. BDAP was associated with the three other components of TTM.ConclusionThe French version of the BDAP shows good structural and psychometric properties. BDAP may be used as a valid tool in French-speaking populations.     

The style of planning action (STOP) questionnaire in OCD spectrum disorders

This article describes the exploratory and confirmatory validation of an everyday style of planning (STOP) questionnaire in a tic disorder (n = 88), Tourette syndrome (n = 76), body-focused repetitive behaviour group (n = 121), obsessive compulsive disorder (n = 251) and a non-clinical control group (n = 127).Exploratory factor analysis was performed on half of the sample and confirmatory analysis on the other half. A three factor solution accounted for 38% of the variance. The factors were labelled respectively: overcomplication, overpreparation, and overactivity. The internal consistency for the overcomplication score and total score was high and for the other two scales, satisfactory. Test–retest was satisfactory and the subscales discriminated amongst clinical groups, and clinical groups from controls. All subscales became significantly less pathological following cognitive behavioural treatment. Convergent validity showed strong correlations with depression, anxiety and perfectionism but not impulsivity. The study confirms style of action as an important characteristic of obsessive compulsive spectrum disorders. Further analysis of the structure of each factor is warranted.     

Étude exploratoire de la stabilité à long terme des indices standard du WISC-IV

By a Test–Retest procedure, this study explores the long-term stability of the French WISC-IV index scores. The average Test–Retest interval was 2.33 years. The sample consisted of 96 non-clinical children aged between 8 and 12 years. Mean difference between the two testings was not statistically significant for VCI, PRI, WMI, GAI and FSIQ. Test–Retest reliability correlations between the two assessments are high for VCI, GAI and FSIQ (ranging from .81 to .82). An analysis of the performance differences between two assessments indicates intra-individual stability for WMI and GAI. In sum, only GAI demonstrates reliable long-term stability at an inter-and intra-individual level.     

Morningness–Eveningness Scale for Children (MESC): Spanish normative data and factorial invariance according to sex and age

The purpose of the current study was to test the psychometric properties of the Morningness–Eveningness Scale for Children (MESC) to establish normative data, determine cut-off scores for differentiating between morning, intermediate and evening types, and test factorial invariance according to sex and age in a Spanish adolescent population. Additionally, self-reported sleep habits were related to morningness–eveningness (M–E) to study their convergent validity. A sample of 5387 Spanish youth aged 10–16 years old (50% girls) were included in this study. The results revealed that the MESC has acceptable reliability (α = .70), good fit to empirical data with a one-dimensional factorial structure, and metric invariance according to sex and age. M–E scores decreased with age, and boys scored higher in M–E compared to girls. Age and sex size effects were moderate and slight, respectively. The relationship between M–E and sleep habits indicated a delayed pattern of sleep–wake habits in evening types compared to morning types. The Spanish version of the MESC possesses good psychometric properties regarding reliability, metric factorial invariance and convergent validity with self-reported sleep habits.     

French validation of the Twenty-Item Value Inventory

IntroductionPersonal values are important for understanding psychological phenomena by serving as predictors of individuals’ attitudes and behavior. The Twenty-Item Value Inventory (TwIVI, Sandy et al., 2017) was developed to assess values with items from the Portrait Values Questionnaire (PVQ, Schwartz et al., 2001).ObjectiveThe goal of this study was to assess the reliability and validity of the French version of the TwIVI.MethodTwo French-Canadian samples of adults (N1 = 825; N2 = 429) were recruited in order to test the reliability and validity of the TwIVI.ResultsResults revealed that the French version of the TwIVI showed satisfying temporal stability, convergence validity with the PVQ, and concurrent validity with personality traits. Some issues were observed for internal consistency and structural validity, assessed with both multidimensional scaling and exploratory structural equation modeling.ConclusionOverall, these findings partially support the psychometric qualities of the French version of the TwIVI. Implications for theory and research on values are discussed.
