Création et validation d’une version française du questionnaire AttrakDiff pour l’évaluation de l’expérience utilisateur des systèmes interactifs

IntroductionWhile user experience (UX) evaluation is a core concern within the field of human–computer interaction (HCI), there is currently no valid self-administered UX evaluation tool in French. The AttrakDiff 2 scale (Hassenzahl, Burmester, & Koller, 2003) is a UX evaluation tool, which relies on a theoretical model distinguishing pragmatic and hedonic qualities of interactive systems.ObjectiveThis paper describes the translation and validation of the French version of the AttrakDiff 2 scale in order to ease UX assessment in French-speaking users.MethodFollowing the cross-cultural methodology developed by Vallerand (1989), the questionnaire was translated by trilingual researchers before being back-translated and validated by a panel of experts. A pre-test was conducted on 26 participants. The characteristics of the French version of the AttrakDiff 2 scale were then evaluated through a quantitative online study involving a sample of 381 users.ResultsThe results confirm the expected 3 factors structure and a good internal consistency of each subscale. The links between factors are consistent with Hassenzahl's theoretical model (2003) where pragmatic and hedonic perceived attributes combine to form a judgment of attractiveness.ConclusionThe current French version of the AttrakDiff 2 scale is globally reliable with regards to the initial German version and presents satisfactory levels of validity and reliability.     

Preadolescent Decision‐Making Competence Predicts Interpersonal Strengths and Difficulties: A 2‐Year Prospective Study

Recent research has demonstrated that decision‐making competence (DMC), a latent construct reflecting individual differences in rational thought, is predictive of real‐world decision outcomes at various stages of life. This construct has been shown to be associated with concurrent and retrospective accounts of health‐risking behavior, but its predictive validity has yet to be demonstrated. In the present study, we examine this issue using a 2‐year prospective, multiple‐informant design. Specifically, we tested the degree to which preadolescent DMC (PA‐DMC) obtained at ages 10–11 years (Time 1; N = 101) predicted both self‐reports and caregiver reports of emotional, behavioral, and peer‐related difficulties obtained 2 years later (Time 2; N = 76). Holding variables such as numeracy and inhibitory control constant, lower Time 1 PA‐DMC scores predicted greater reported Time 2 psychosocial difficulties (i.e. peer, conduct, emotional, and hyperactivity/inattention problems). Additionally, higher PA‐DMC scores were associated with greater self‐reported prosocial behaviors at Time 2. These results highlight the utility of testing individual differences in rational responding. We discuss the potential for improving children's decision‐making processes.

Coloured Letters and Numbers (CLaN): A reliable factor-analysis based synaesthesia questionnaire

Synaesthesia is a heterogeneous phenomenon, even when considering one particular sub-type. The purpose of this study was to design a reliable and valid questionnaire for grapheme-colour synaesthesia that captures this heterogeneity. By the means of a large sample of 628 synaesthetes and a factor analysis, we created the Coloured Letters and Numbers (CLaN) questionnaire with 16 items loading on 4 different factors (i.e., localisation, automaticity/attention, deliberate use, and longitudinal changes). These factors were externally validated with tests which are widely used in the field of synaesthesia research. The questionnaire showed good test–retest reliability and construct validity (i.e., internally and externally). Our findings are discussed in the light of current theories and new ideas in synaesthesia research. More generally, the questionnaire is a useful tool which can be widely used in synaesthesia research to reveal the influence of individual differences on various performance measures and will be useful in generating new hypotheses.     

Evaluation of the London (Ontario) Community Group Treatment Programme for Children Who Have Witnessed Woman Abuse

Summary

Group intervention for children exposed to woman abuse is increasingly used to respond to the psychological needs of children exposed to woman abuse. This article describes a community group model of intervention for children exposed to woman abuse, and an evaluation approach used to assess the impact of such groups. The collaborative development of questionnaire/interview evaluation instruments for this purpose is described, and the set of instruments is presented in its entirety. The main instrument, entitled Child/Teen Witness to Woman Abuse Questionnaire, was tailored to the content of the groups and covers topics such as definitions and understanding of abuse, safety skills, beliefs and attitudes about abuse, perceived responsibility for abuse, alternatives to violence, non-violent conflict resolution strategies, and help seeking skills. Both closed-ended and open-ended questions are employed. Separate questionnaires assess consumer (mother/caregiver and child) satisfaction and feedback. The results of a study evaluating the groups are described, which showed good changes from pre to post intervention, as well as a high degree of satisfaction among children and mothers with regard to the groups. Feedback from children and mothers as to suggested improvements in the group is also described.     

EPQ信度概化的跨文化比较及其启示

对中国7种主要的心理学杂志,于1998-2008年间发表的与EPQ有关的研究报告或论文做信度概化分析,并与Caruso等人对其他国家的EPQ信度概化分析结果作比较。分析结果表明：中外心理量表使用者都存在严重的“信度引入”的状况;分量表的分数的标准差是信度系数最重要的预测变量;但其他预测变量有所不同。提供的启示是：使用心理量表时一定要报告当前样本的信度系数;不符合心理量表特性要求而增加项目,不一定能提高测验结果的信度。     

Rasch analysis and item reduction of the hypomanic personality scale

The aim of the current study was to reduce the number of items in the 48-item hypomanic personality scale (HPS) and determine whether a unidimensional scale of the hypomanic trait could be derived. Previously collected HPS data from University students (n = 318) were applied to the Rasch model (one-parameter item response theory). Overall scale and individual item fit statistics were used to judge fit to the model and item maps employed to determine coverage of the trait. Cronbach’s Alpha and correlations with other questionnaires pre- and post-item reduction were evaluated. Rasch analysis indicated that the original HPS was not unidimensional, had significant redundancy and differential item functioning by age and gender. An iterative process of item reduction produced a 20-item HPS (HPS-20) that retained the concepts of the original HPS and had excellent fit to the Rasch model (χ² p = 0.27). Unidimensionality of the HPS-20 was confirmed. The traditional psychometric properties of the HPS-20 and coverage of the underlying hypomanic construct were similar to the original. It was possible to derive a unidimensional measure of the hypomanic trait. Further use of the HPS-20 is encouraged as it may increase understanding of the risk factors for affective disorders.     

The Child Food Rejection Scale: Development and validation of a new scale to assess food neophobia and pickiness among 2- to 7-year-old French children

IntroductionThe two strongest obstacles to extend children's consumption of fruit and vegetables are food neophobia and pickiness, assumed to be the main kinds of food rejection in children. Accordingly, psychometric tools that provide a clear assessment of these kinds of food rejections are greatly needed.ObjectiveTo design and validate a new scale for the assessment of food neophobia and pickiness, thus filling a major gap in the psychometric assessment of food rejection by French children.MethodWe concentrated on French children aged 2–7 years, as no such scale exists for this young population, and on the two known dimensions of food rejection, namely food neophobia and pickiness, as the nature of the relationship between them is still unclear. The scale was tested on two samples (N₁ = 168; N₂ = 256) of caregivers who responded for their children. Additionally, a food choice task was administered to 17 children to check the scale's predictive validity.ResultsThe resulting scale, called the Child Food Rejection Scale (CFRS), included six items relating to food neophobia and five items relating to pickiness. A factor analysis confirmed the two-dimensional structure of the scale. Internal consistency, test–retest reliability, and convergent and discriminant validity were all satisfactory. Moreover, results from the food choice task showed that scores on the CFRS accurately predicted children's attitudes toward new and familiar foods.ConclusionTaken together, these findings suggest that the CFRS, a short and easy-to-administer scale, represents a valuable tool for studying food rejection tendencies in French children.     

The time-saving bias, speed choices and driving behavior

When drivers are asked to estimate how much time can be saved by increasing speed, they generally underestimate the time saved when increasing from a relatively low speed and overestimate the time saved when increasing from a relatively high speed. This time-saving bias has been demonstrated to affect drivers’ estimations of driving speed as well as drivers’ personal choice of speed. Specifically, drivers with a high time-saving bias chose unduly high speeds, which sometimes results in speeding, more frequently than drivers with a lower degree of the bias. This study sought to determine whether this relationship would be mediated by individual differences in driving behavior – including drivers’ attitudes, norms and habits regarding speeding behavior as well as their level of aberrant driving behavior (committing aggressive or ordinary violations, errors or lapses in driving, measured by the Driver Behaviour Questionnaire). The results showed that the time-saving bias predicted estimations of required speed better than any of these factors, and also better than drivers’ age, gender, education and income, as well as the number of years they have had a license and their monthly driving kilometrage, their prior speeding violations and crash involvement. In predicting drivers’ personal speed choices, the time-saving bias was second only to the frequency of committing ordinary violations.     

Development of the Cognitive Dysfunction Questionnaire (CDQ) in a population based sample

The study reports on the development of a questionnaire for assessment of adult cognitive dysfunction (CDQ). Participants in a population-based sample (65±15 years, N=370) responded to a 90-item pilot version covering multiple aspects of memory/cognition. Based on exploratory principal components analyses and correlations with criterion measures of cognitive functioning (MMSE, Block Design, semantic/episodic memory), 20 items loading on 6 components were selected for the final version of the questionnaire. Cronbach's α for the total score was 0.90. There was evidence of construct validity as judged by correlations between CDQ scores, objective cognitive measures, and a subjective memory measure (PRMQ). Discriminant validity was demonstrated by a low and non-significant correlation with depressive symptoms. Further evidence of construct validity was provided by correlations with age and educational attainment. In conclusion, the CDQ is promising as a self-rating screening tool for cognitive dysfunction, and will be the subject of further development and validation.     

The general factor of personality: Questions and elaborations

Predictions from Rushton’s theory that a general factor of personality (GFP) has evolved based on effective social participation were examined in two large samples of adult Australian twins (5834 and 3672 individuals) and their relatives (8303 and 2677). General factors based on items and scales were compared to each other, across two different questionnaires, and between adults and adolescents. Behavior-genetic analyses based on the twin samples tested predictions comparing GFPs to scales with the GFP partialled out. Some support was found for Rushton’s theory, but the GFP was only marginally more heritable than the GFP-free scales and was not especially marked by the expected non-additivity of its genetic variance; moreover, the adult and adolescent GFPs showed substantial differences.
