L'insatisfaction corporelle, définie comme la différence entre le corps perçu et le corps idéal (Cash, 2002), a été mise en évidence comme facteur de risque de nombreux troubles et symptômes psychopathologiques. Ainsi, l’une des priorités de la recherche sur l’insatisfaction corporelle est d’identifier les processus psychologiques impliqués dans le développement et le maintien de l’insatisfaction corporelle. L'analyse de la littérature sur l’insatisfaction corporelle, la rumination, le perfectionnisme et l’autorégulation a révélé plusieurs résultats intéressants ainsi qu’un manque d’information dans ce domaine. La plupart des recherches sur le rôle de ces processus dans l'insatisfaction corporelle sont transversales. Ainsi, il a été avancé que davantage de recherche était nécessaire pour examiner les facteurs de risque causaux impliqués dans l'insatisfaction corporelle (Watson et al., 2016). Les objectifs de cette recherche étaient de développer et tester plusieurs instruments de mesure (questionnaire, tâches implicites et comportementales) et protocoles (conception longitudinale, inductions expérimentales) afin d'explorer les relations causales entre perfectionnisme, rumination, autorégulation et insatisfaction corporelle en tenant compte des différences entre hommes et femmes. Les résultats suggèrent des cercles vicieux entre insatisfaction corporelle, rumination et perfectionnisme, ainsi que des différences entre hommes et femmes sur les relations entre ces processus et l'insatisfaction corporelle. De plus, nos résultats concernant les outils de mesure implicites et comportementaux du perfectionnisme comme alternatives aux mesures classiques d’auto-évaluation sont encourageants. Un modèle présentant la manière dont ces cercles vicieux pourraient contribuer à l'insatisfaction corporelle est proposé et des orientations futures sont explorées dans la discussion générale. / Body dissatisfaction, defined as the difference between the perceived and the desired body (Cash, 2002), has been highlighted as a risk factor of numerous psychopathological disorders and symptoms. Thus, one of the priorities in body dissatisfaction research is to identify psychological processes involved in the development and maintenance of body dissatisfaction. The overview of the literature about body dissatisfaction, rumination, perfectionism, and self-regulation revealed several interesting results and also a lack of information in this field. Most of the research on the role of these processes in body dissatisfaction is cross-sectional. Thus, it has been brought forward that more research is needed to examine the causal risk factors involved in body dissatisfaction (Watson et al., 2016). The objectives of this research were to develop and test several measurement instruments (i.e., questionnaire, implicit and behavioural tasks) and protocols (i.e., longitudinal design, experimental inductions) to explore the causal relationships between perfectionism, rumination, self-regulation and body dissatisfaction, while taking into account gender differences. The results suggest vicious circles between body dissatisfaction, rumination, and perfectionism, and differences between men and women on the relationships between those processes and body dissatisfaction. More, our results about implicit and behavioural measurement instruments of perfectionism as alternative to the classical self-report measures are encouraging. A model presenting how all these vicious circles could contribute to body dissatisfaction is proposed and futures directions are explored in the general discussion.

abstract: ABSTRACT Perfectionism has been conceptualized as a relatively stable, independent, multidimensional personality construct in research during the last two decades. Despite general agreement that perfectionism is dimensional in nature, analyses using these instruments vacillate between a dimensional approach and a categorical approach (Broman-Fulks, Hill, & Green, 2008; Stoeber & Otto, 2006). The goal of the current study was two-fold. One aim was to examine the structural nature of two commonly used measures of perfectionism, the APS-R and the HFMPS. Latent class and factor analyses were conducted to determine the dimensions and categories that underlie the items of these two instruments. A second aim was to determine whether perfectionism classes or perfectionism factors better predicted 4 criterion variables of career indecision. Results lent evidence to the claim that both the APS-R and HFMPS are best used as dimensional, rather than categorical instruments. From a substantive perspective, results indicated that both positive and negative aspects of perfectionism successfully predicted career indecision factors. The study concludes with a discussion of limitations, and implications for future research and counseling individuals with career indecision concerns. / Dissertation/Thesis / Ph.D. Counseling Psychology 2013

Music Performance Anxiety is something that has affected a number of musicians and numerous studies have been conducted on performance anxiety in adult musicians. However, research on performance anxiety in children and adolescence is still lacking when compared to literature on adult and music performance anxiety. This study examined the signs and symptoms that children (ages 8-12) and teenagers (ages 13-17) feel and the levels of performance anxiety they perceive. In addition, this study also examined levels of perfectionism, self-efficacy and gender as predictors of anxiety and compared these with levels of anxiety. Sixty-five participants completed three questionnaires and a demographic survey. Results suggest a tentative increasing relationship between music performance anxiety and age while no relationship between gender and anxiety was found. Strong relationships between perfectionism and self-efficacy with anxiety indicate that students with high levels of perfectionism and low levels of self-efficacy are more likely to have high levels of performance anxiety. Just as previous studies with adults have found, our findings in children and adolescents suggest that perfectionism may render people vulnerable to performance anxiety while self-efficacy may be an important buffer against this anxiety.
