Introduction
My reseach projects focus primarily on personality assessment, both normal and pathological, and in the role traits play in psychosocial functioning. I'm also interested in test adapation and translation, and in the study of professionnal practices in vocational counseling.

The three dimensions of psychopathic traits in childhood predict high levels of conduct problems. Theoretical conceptions suggest that, in addition to predicting the onset of conduct problems, traits also contribute to their developmental pathways. However, little is known about the associations between the trajectories of the three dimensions of p...

The use of unproctored Internet-based testing (IBT) for personality assessment is increasingly popular, especially in personnel selection.

The most recent version of the widely used NEO Inventories, the NEO-PI-3, has been translated in several languages worldwide, including Canadian French.

Conference Paper
Studies on the equivalence of Internet and paper-and-pencil tests have shown mixed results (e.g. Aluja e tal., 2007; Joubert & Kriek, 2009 ; Meade e tal. , 2007; Ployhart e tal., 2003).One suggested explanation is that social desirability could be lower in Internet tests (Heerwegh, 2009; Joinson, 1999). In this regard, it was suggested that persona...

Project
Goal: The primary objective of this study is to assess the cross-cultural validity of the FFiCD by examining its measurement invariance across nine countries from four continents: Belgium, Burkina Faso, Canada, France, India, Spain, Switzerland, Togo and the United States. Specifically, we aimed to test whether a) the FFiCD factor structure is equivalent across countries (configural invariance), b) its latent factors are defined by the same items equally across countries (metric invariance), and c) identical test scores for individuals from different cultures indicate equal levels of maladaptive personality traits (scalar invariance). The FFiCD was initially developed in English and has since been translated in several languages including Spanish (Aluja et al., 2021; Sorrel et al., in press), but not French. In fact, to our knowledge, there is currently no instrument available to assess ICD-11 maladaptive personality traits among French-speaking individuals. Therefore, a complementary aim of this study was to produce and validate a French and translation of the FFiCD. We also wished to provide additional validity evidence for the FFiCD by assessing: a) its convergent validity with the Big Five dimensions, and b) its criterion validity in relation to self-reported mental disorder diagnoses and consulting.

With the introduction of the Alternative Model of Personality Disorders in the DSM-5 (APA, 2013), a need for short measures of the level of personality functioning has emerged, both for screening purposes as well as for assessing change during treatment.
