Objectives Self-esteem may affect the processing and regulation of emotion. However, it is unclear whether differences in self-esteem are associated with changes in initial emotional appraisal or engagement of emotion regulation. I investigated whether individual differences in self-esteem predicted brain responses to negative emotional stimuli: 1) when they were viewed without intentional regulation; and 2) during downregulation using cognitive reappraisal. Thirdly, I investigated whether self-esteem predicted reappraisal success. Method Twenty-nine healthy adults (age M=47, SD=15; 16 female) performed a cognitive reappraisal emotion regulation task during fMRI scanning. Participants viewed and subsequently reappraised or attended to negative and neutral images. Trait self-esteem (Rosenberg Self-Esteem Scale) was included as a predictor in a whole-brain multiple regression analysis. Analyses were thresholded at p<.005, k>p20, p<.05 family-wise error (FWE)-corrected at cluster-level. The anterior cingulate cortex (ACC; BA32) and the dorsal prefrontal cortex (PFC; BA6) were a priori regions of interest (ROI), since both have previously been reported in fMRI studies of self-esteem and cognitive reappraisal. A post-hoc ROI analysis tested the correspondence of self-esteem-related ACC activation with findings from a meta-analysis of emotion regulation. Ratings of negative emotional intensity following reappraisal trials were subtracted from ratings following attend-negative trials to index reappraisal success. Results Self-esteem was associated with potentiated ACC ROI activation during viewing of negative, compared to neutral, images (MNI x, y, z = -6, 17, 38, k=43, punc=.001 at peak, pFWE=.368 at cluster-level). For reappraisal compared to attended negative images, self-esteem was positively associated with activation in the left posterior insula (MNI x, y, z = -30, -10, 17, k=30, punc<.001 at peak, pFWE=.959 at cluster-level) and negatively associated with activation in the mid cingulate cortex (MNI x, y, z = 3, -34, 35, k=50, punc=.001 at peak, pFWE=.805 at clusterlevel). However, only the post-hoc ACC ROI analysis was significant after multiple comparison correction (MNI x, y, z = -6, 23, 38, k=22, punc=.001 at peak, pFWE=.021 at clusterlevel). For reappraisal, self-esteem was not related to activation in the ACC or dorsal PFC ROIs. Trait self-esteem did not correlate with reappraisal success, r =.16, p =.208. Conclusion Trait self-esteem may affect recruitment of the ACC during initial emotional appraisal. This may reflect successful automatic emotion regulation for high self-esteem, consistent with the demonstrated spatial overlap with a meta-analytic emotion regulation cluster. While selfesteem may affect brain responsivity during cognitive reappraisal, the observed trends must be interpreted carefully, since the findings do not survive correction for multiple comparisons, and emotional outcomes of applying reappraisal do not differ as a function of self-esteem. Taken together, these findings suggest that high trait self-esteem may be advantageous for rapid automatic emotion regulation, but not deliberate cognitive reappraisal.

This thesis explored the relationships between 1) Self-compassion 2) Cognitive Emotion Regulation and 3) Mindfulness Based Stress Reduction (MBSR) and teacher stress in a foreign international school setting. The retrospective, multi-tiered study investigated a total of 177 expatriated teachers working in multiple international schools around the globe; at least 17 of whom indicated that they had completed a MBSR course. A mixed-methods approach was used over three stages utilising the following instruments: 1) an adapted stress impact survey, 2) Teacher Interview Protocol (TIP), 3) the short forms of the Cognitive Emotion Regulation Questionnaire (CERQ-SF), the Self-Compassion Scale (SCS-SF), and the Perceived Stress Scale (PSS-4). Results suggest that teachers’ beliefs about stress correlate with job satisfaction; 82.6% of respondents who reported that stress has ‘hardly any effect’ also reported that they liked their job overall; whereas, 76.9% and 36.4% of respondents that believed stress had affected their teaching ‘some’ or ‘a lot’ reported liking their job, respectively. Results also indicate that higher perceived stress is strongly correlated with both 1) decreased self-compassion (r = -.491, p < .001) and 2) increased use of non-adaptive cognitive emotion regulation strategies, such as Catastrophizing (r= < 0.392, p < .001). All five adaptive cognitive coping strategies were positively correlated with Self-Compassion, four were significant; only Refocus on Planning failed to reach significance at p < .05. The data indicated no statistically significant differences between MBSR and non-MBSR participants, regarding perceptions of stress (PSS-4), self-compassion (SCS-SF), and eight of the nine coping strategies (CERQ-S), with the exception being that MBSR participants experienced reduced Self-Blame (p < 0.007). Conclusions find that policies and practices aimed at supporting the three aspects of self-compassion offer one possible avenue to reducing teacher stress and maladaptive thinking strategies, and thereby increasing job satisfaction, for teachers working in a foreign country.

The purpose of the study was to examine the influences of basic personality traits, cognitive emotion regulation and interpersonal problems on the cognitive aspects of personality disorders. 1298 adult participants (411 males and 887 females) between the ages of 18 and 68 (M = 26.85, sd = 7.95) participated in the study. In the first part of the study, Inventory of Interpersonal Problems was adapted to Turkish, and psychometric properties of the adapted inventory as well as Cognitive Emotion Regulation Questionnaire and Personality Belief Questionnaire were analyzed and were found to have good validity and reliability characteristics. Differences in demographic variables and correlational data for the measures were examined. Direct and mediational models were used to investigate the relationship among basic personality traits, cognitive emotion regulation, interpersonal problems and personality disorder beliefs. The results revealed that openness and neuroticism were associated with positive and negative emotion regulation, respectively. Neuroticism, negative valence and catastrophization were associated with interpersonal problems positively whereas extraversion was associated with them negatively. In terms of personality psychopathology, neuroticism, catastrophization, blaming others, and being cold and domineering in relations were found to be positively associated with personality disorder beliefs. Furthermore, the effect of neuroticism and negative valence on personality disorder beliefs was mediated by interpersonal problems, with the effect of negative valence also being mediated by negative cognitive emotion regulation. The findings and their implications with suggestions for future research and clinical applications, were discussed in the light of relevant literature.

Researchers have not been able to ascertain how survivors of childhood trauma, especially sexual abuse, develop resilience. To explore resilience and what influences its development, this mixed-method study investigated the roles of cognitive emotion regulation and proactive coping by using a critical-realist ontology. The data was collected from eight women (between ages 25 and 56) who considered themselves to be resilient survivors of severe child sexual abuse. Harvey’s (2000) Multidimensional Trauma Recovery and Resiliency Interview (MTRR-I), the Cognitive Emotion Regulation Questionnaire (Garnefski, Kraaij&Spinhoven, 2002) and Greenglass’s (1999) Proactive Coping Inventory were used to gather the data necessary to determine whether resilience is influenced by cognitive emotion regulation strategies and proactive coping and to attempt to define what could be considered as traits of resilience in survivors or child sexual abuse. Through thematic analysis, approximately 50 a-priori codes were generated and grouped into 23 themes using the Atlas.ti program. The objective of this study is to explore the relationship between cognitive emotion regulation, proactive coping and resilience in order to better understand, and develop intervention processes that can provide survivors of child sexual abuse and other trauma with the resources needed to be more resilient. Although causality could not be determined between these variables, it became evident that the more often a participant employs adaptive cognitive emotion regulation strategies and the higher the scores on the Proactive Coping Inventory are, the more resilient the participant tends to be. The participants who displayed higher levels of resilience also verbalised that they felt they had dealt with the abuse and had managed to move on in their lives. Even though all the participants considered themselves to be resilient, half of them were functioning at a noticeably lower rate of resilience than the others. All the participants claimed to rely on spiritual strength in some way and attribute their resilience to their faith in God. The higher the levels of resilience, the more the participants used adaptive cognitive emotion regulation strategies and proactive coping; and the more optimistic their views of the future and the more they considered their lives to be meaningful. Because the study was based on the ecological model of human development (Bronfenbrenner, 1995, 2005,) the interplay of the proximal environment, the individual, the social context and the changes that have taken place over time, were all taken into consideration because resilience, cognitive emotion regulation and proactive coping skills all develop within and between the same systems in which an individual develops. However, Bronfenbrenner (2005) states that the family is no longer taking the responsibility for the upbringing of children as it should and that other settings in society have had to step in to fulfil the role. One aspect of mental health is the ability to develop spiritually and since schools may not include religious instruction because it is the responsibility of the family, it happens that children are not being developed spiritually and this could influence the way in which individuals deal with traumatic childhood experiences. / Thesis (PhD)--University of Pretoria, 2011. / Educational Psychology / unrestricted

Happiness, anger, surprise, irritation… if we note down the emotions that we go through on a given day, the list will most probably be quite long. A surge of studies on the bidirectional interaction between emotion and cognition suggests that we need emotional appraisals in order to lead a successful life and maintain our personal, social and economic integrity (Bechara, 2005; Damasio, 1994; Fox, 2008; Gross &amp;amp; Thompson, 2007; Walter, 2005). And yet, we seldom ‘just’ experience emotions, but often try to influence them to best fit our current goals. Based on the assumption that emotional reactions entail changes on various levels, and that these changes happen in- or outside of our awareness, affective science has adopted emotion regulation as one of its major research topics (Beauregard, Levesque, &amp;amp; Paquette, 2004; Gross, 1999; Ochsner, 2007). In fact, neural (e.g. amygdala activation) and behavioral (e.g. feeling of negativity) correlates of emotional reactions are effectively reduced by top-down processes of explicit and implicit control (Drabant, McRae, Manuck, Hariri, &amp;amp; Gross, 2009; Levesque, et al., 2003; Ochsner, Ray, et al., 2004). Furthermore, evidence from studies investigating voluntary thought control suggests that control strategies may have lasting and paradoxical consequences (Abramowitz, Tolin, &amp;amp; Street, 2001; Wegner, 2009). In a very recent investigation, lasting effects of regulation were also shown after the cognitive control of emotions: the activation timecourse of the amygdala was significantly increased immediately following regulation, and this difference was also related to the activation of the amygdala to the same stimuli a few minutes later (Walter, et al., 2009). Aside from these contextual or qualitative influences, emotional processing also differs between individuals: genetic variation within the serotonergic system for instance is known to affect emotional reactivity both on the behavioral and on the neural level (Hariri, et al., 2005; Hariri, et al., 2002; Lesch, et al., 1996). In the present work, the temporal dynamics of volitional emotion regulation were investigated in three studies. It was hypothesized that both the subjective experience of negativity and the amygdala activation can be attenuated by the detachment from negative emotions, which in turn leads to an immediate neural aftereffect after the offset of regulation. Furthermore, volitional emotion regulation was expected to be capable of reducing or even obliterating genetically mediated amygdala hyperreactivity to negative emotional cues. Similar to previous investigations (Walter, et al., 2009), pictures of aversive or neutral emotional content were presented while participants were instructed to react naturally to half of the pictures, and to regulate their emotional response upon the other half of the stimuli. The first two studies of the present work were designed to further characterize the immediate aftereffect of volitional regulation in the amygdala: Study 1 included behavioral ratings of negativity at picture offset and at fixation offset in order to provide behavioral measures of experiential changes, while in Study 2, participants continued to experience or regulate their emotions during a “maintain” phase after picture offset. The primary goal of Study 3 was to evaluate whether volitional emotion regulation can reduce genetically mediated amygdala hyperreactivity to aversive emotional material in individuals with the short variant of the serotonin transporter genotype (Hariri, et al., 2005; Hariri, et al., 2002), and whether the immediate aftereffect is also influenced by the serotonin transporter genotype. In all three studies, the amygdala was significantly activated by aversive versus neutral stimuli, while cognitive emotion regulation attenuated the activation in the amygdala and increased the activation in a frontal-parietal network of regulatory brain regions. This neural effect was complemented by the behavioral ratings which show that the subjective experience of negativity was also reduced by detachment (Study 1). Also in all three studies, an immediate aftereffect was observed in the amygdala following the end of regulation. Moreover, the preoccupation with the previously seen pictures after the scanning session varied across the experimental conditions (Studies 2 and 3). Volitional regulation proved effective in reducing amygdala activation to negative stimuli even in 5-HTTLPR short allele carriers that show an increased reactivity to this type of cue. At the same time, functional coupling of the ventrolateral and medial orbital prefrontal cortex, the subgenual and the rostral anterior cingulate with the amygdala was higher in the s-group. However, in Study 3 the immediate aftereffect was found only in l/l-homozygote individuals following the regulation of fear. Taken together, the results of the three studies clearly show that volitional regulation is effective in reducing behavioral and neural correlates of the experience of negative emotions (Levesque, et al., 2003; Ochsner, Bunge, Gross, &amp;amp; Gabrieli, 2002; Ochsner, Ray, et al., 2004), even in the case of a genetically mediated hyperreactivity to such materials. Thus, it seems reasonable to assume that conscious will can effectively counteract genetic determinants of emotional behavior. Moreover, the present results suggest that the temporal dynamics of volitional emotion regulation are characterized by a paradoxical rebound in amygdala activation after regulation, and that the immediate aftereffect is a marker of the efficiency of the initial and the sustained effects of emotion regulation (Walter, et al., 2009). In summary, the successful replication of the immediate aftereffect of emotion regulation in all three studies of this dissertation opens up exciting new research perspectives: a comparison of the short- and long-term effects of different regulatory strategies, and the investigation of these effects also in positive emotions would complement the present results, since the neural mechanisms involved in these processes show some characteristic differences (Ochsner, 2007; Staudinger, Erk, Abler, &amp;amp; Walter, 2009). A comprehensive characterization of this neural marker and its implications for emotional experience might also be useful with respect to clinical applications. The detailed examination of the various time scales of emotional regulation might for instance inform the diagnostic and therapeutic interventions in affective disorders that are associated with emotional dysfunctions (Brewin, Andrews, &amp;amp; Rose, 2000; Johnstone, van Reekum, Urry, Kalin, &amp;amp; Davidson, 2007). Ultimately, we might thus come to understand the neural underpinnings of what the feelings we have today have to do with the feelings we had yesterday – and with the feelings with might have tomorrow.

A capacidade de influenciar a experi?ncia e express?o emocional, conhecida como regula??o emocional (RE), pode ser cr?tica ao lidar com n?veis significativos de estresse. Especificamente, a RE atrav?s de cogni??es, ou pensamentos (ou seja, Regula??o Emocional Cognitiva, REC), ajuda os indiv?duos a manter o controle sobre sua experi?ncia emocional durante, ou depois de serem expostos a eventos estressores, ou traum?ticos. O Question?rio de Regula??o Emocional Cognitiva (CERQ), foi desenvolvido para medir nove diferentes estrat?gias de REC que se referem ? maneira consciente e atencional de lidar com eventos de vida amea?adores, ou negativos. Objetivos: Os objetivos gerais desta disserta??o foram desenvolver e investigar as evid?ncias de validade da vers?o brasileira do CERQ (Estudo 1) e investigar a rela??o entre a exposi??o a traumas, estrat?gias cognitivas de RE, afeto e Sintomas de Estresse P?s-Traum?tico (SEPT) atrav?s de um modelo de media??o dupla (Estudo 2). M?todo: Uma amostra de 445 estudantes universit?rios completou um Question?rio S?cio-Demogr?fico, a Life of Events Checklist (LEC-5), a vers?o brasileira do CERQ, a Positive and Negative Affect Schedule (PANAS) e a Posttraumatic Symptoms Checklist (PCL-5) em uma plataforma de pesquisa on-line. Para o Estudo 1, o processo de adapta??o da vers?o brasileira do CERQ incluiu tradu??o, retro-tradu??o, avalia??o de ju?zes e teste em 30 participantes da popula??o-alvo. As evid?ncias de validade de construto foram avaliadas atrav?s de an?lise fatorial confirmat?ria, da consist?ncia interna atrav?s dos alfas de Cronbach e de correla??es com as vari?veis afetivas mensuradas pelo PANAS. Para o Estudo 2 foram realizadas an?lises preliminares de correla??o e de regress?o linear m?ltipla para investigar associa??es entre tipo de trauma, estrat?gias cognitivas de regula??o emocional, afeto e severidade de SEPT. Em seguida, um modelo com rumina??o e afeto negativo como mediadores do efeito da exposi??o ao trauma les?o moral causada por outros sobre os SEPT foi testado usando o macro PROCESS para o SPSS. Resultados: As an?lises de validade mostraram que a estrutura original do CERQ possui boa validade fatorial na amostra e alta confiabilidade, com ? de Cronbach variando entre .71 e .88. An?lises preliminares de associa??o entre tipo de trauma, estrat?gias de regula??o emocional cognitiva, afeto e SEPT mostraram que o tipo de trauma de les?o moral causada por outros, rumina??o e afeto negativo s?o preditores significativos da gravidade de SEPT. Ao testar o modelo de media??o dupla, os resultados sugerem que a rumina??o ? um mediador forte e independente entre o tipo de trauma de les?o moral causada por outros e SEPT, enquanto afeto negativo ? um mediador apenas quando a rumina??o est? presente no modelo. Discuss?o: Nossos resultados indicam que a vers?o brasileira do CERQ ? uma ferramenta v?lida e confi?vel para avaliar as estrat?gias cognitivas de regula??o emocional e que os indiv?duos expostos ao tipo de trauma de les?o moral causada pelos outros utilizam rumina??o como uma estrat?gia de regula??o emocional cognitiva com mais frequ?ncia. O uso aumentado dessa estrat?gia amplifica os n?veis de afeto negativo que acaba levando a n?veis mais elevados de SEPT. Em geral, esses resultados podem influenciar pesquisas e auxiliar no desenvolvimento e melhoria de interven??es cognitivas para indiv?duos expostos a eventos traum?ticos. / Background: Literature suggests that emotional responses are associated to the development and maintenance of Posttraumatic Stress Disorder (PTSD) symptoms. The ability to influence emotional experience and expression, known as emotion regulation (ER), can be critical when dealing with significant levels of stress. Specifically, ER through cognitions, or thoughts (i.e. Cognitive Emotion Regulation; CER), helps individuals to maintain control over their emotional experience during, or after being exposed to stressful, or traumatic events. The Cognitive Emotion Regulation Questionnaire (CERQ) was developed to measure nine different CER strategies that refer to the conscious and attentional way people deal with threatening, or negative life events. Objectives: Therefore, the general purposes of this thesis were to develop and evaluate validity evidences of the Brazilian version of the CERQ (Study 1) and to investigate the relationship between trauma exposure, cognitive emotion regulation strategies, affect and Posttraumatic Stress Symptoms (PTSS) testing for a double mediation model (Study2). Method: A sample of 445 university students completed a Socio-Demographic Questionnaire, the Life of Events Checklist (LEC-5), the Brazilian version of the CERQ, the Positive and Negative Affect Schedule (PANAS) and the Posttraumatic Symptoms Checklist (PCL-5) on an on-line research platform. For Study 1, adaptation process of the Brazilian version of the CERQ included translation, backtranslation, expert committee?s evaluation, and testing on 30 participants from the target population. Validity evidence was assessed through confirmatory factor analysis, internal consistency through the Cronbach?s alpha analysis, and correlations with the affective variables measured by the PANAS. For Study 2, preliminary correlation and multiple linear regression analyses were conducted to investigate associations among trauma type exposure, cognitive emotion regulation strategies, affect and PTSS severity. Next, a model positing rumination and negative affect as double mediators of the effect of trauma type of moral injury by others on PTSS was tested using the PROCESS macro for SPSS. Results: Validity analyses showed that the original structure of the CERQ has good factorial validity in the sample and high reliabilities, with Cronbach?s ? ranging between .71 and .88. Preliminary analyses of the association among trauma type, cognitive emotion regulation strategies, affect and PTSS showed that trauma type of moral injury, rumination and negative affect were significant predictors of PTSS severity. When testing for the double mediation model, results suggested that rumination is a strong and independent mediator between trauma type moral injury by others and PTSS, while negative affect is a mediator only when rumination is also included. Discussion: Our results indicate that the Brazilian version of the CERQ is a valid and reliable tool for assessing cognitive emotion regulation strategies, and that individuals who are exposed to trauma type of moral injury by others engage more frequently in rumination as a cognitive emotion regulation strategy, which in turn amplifies levels of negative effect that ends up leading to higher levels of PTSS. Overall, these results can influence further researches and aid the development and improvement of cognitive treatment interventions for individuals exposed to traumatic events.

L’extirpation compulsive des poils et de la peau, ainsi que le rongement des ongles constituent des gestes destructeurs et non-fonctionnels appartenant à la catégorie des comportements répétitifs centrés sur le corps (CRCC). Dans les dernières années, plusieurs études ont souligné des caractéristiques communes entre les CRCC et les troubles alimentaires (TA). Des modèles théoriques ont notamment mis en lumière l’importance des difficultés de régulation émotionnelle chez ceux atteints de CRCC et de compulsions alimentaires. Plusieurs auteurs ont suggéré que la honte possédait un rôle important dans le déclenchement et le maintien de ces comportements impulsifs. De plus, la honte physique et les conséquences associées à ces comportements contribueraient à la persistance du cycle de la honte. À ce jour, de nombreux processus cognitifs utilisés pour caractériser ces conditions restent inexplorés, incluant les stratégies cognitives de régulation émotionnelle et l'autocritique (i.e., évaluation néfaste et punitive de soi). L’étude de ces processus cognitifs et de la honte contribuera au raffinement des modèles théoriques existants. Par ailleurs, l’étude en parallèle des CRCC et des TA permettra de comparer les processus divergents et convergents entre ces conditions souvent concomitantes. Le premier article de cette thèse porte sur une étude en ligne ayant été effectuée par le biais de questionnaires auto-rapportés auprès d’un échantillon d’adultes provenant de la population générale (n=76). De nature exploratoire, cette étude vise à identifier la relation entre la sévérité des symptômes de CRCC et de TA, l’autocritique, la honte et les stratégies cognitives de régulation émotionnelle inadaptées. Les résultats montrent une corrélation positive entre les symptômes de CRCC et de TA et les processus étudiés. De plus, ces résultats indiquent que la honte et les stratégies de régulation émotionnelle inadaptées expliquent en partie la sévérité des symptômes de CRCC, tandis que l’autocritique explique la sévérité des symptômes de TA. Le deuxième article présenté dans le cadre de cette thèse porte sur une étude expérimentale effectuée auprès de trois groupes de femmes, soit un groupe témoin (n=18), un groupe atteint de CRCC (n=18) et un groupe s’engageant dans des compulsions alimentaires et souffrant d’un TA (n=18). L’objectif principal de cette étude est d’explorer le rôle de la honte dans l’envie de s’engager dans des CRCC et des compulsions alimentaires. Les résultats de cette étude confirment que la honte augmente l’envie de s’engager dans des CRCC, sans toutefois augmenter l’envie de s’engager dans des compulsions alimentaires. Par ailleurs, les résultats mettent en lumière la présence d’un sentiment de honte subséquemment à des épisodes de CRCC et de compulsions alimentaires. Les données obtenues soulignent l’importance de la honte comme facteur précipitant un épisode de CRCC, ainsi que comme facteur de maintien des CRCC et des compulsions alimentaires. Pour conclure, les résultats de cette thèse doctorale appuient le rôle de la honte dans la sévérité des symptômes de CRCC, ainsi que comme facteur déclencheur et de maintien des épisodes de CRCC. En plus de discuter de l’ensemble des résultats de la présente thèse, les principales limites et les forces sont présentées dans la discussion. Les implications théoriques et cliniques, ainsi que des pistes pour orienter les recherches futures sont également proposées. / Compulsive hair-pulling, skin-picking and nail-biting are destructive and non-functional habits that are classified as body-focused repetitive behaviors (BFRBs). Over the past few years, several studies have highlighted common characteristics between BFRBs and eating disorders (EDs). Notably, theoretical models have highlighted the role played by emotional regulation difficulties during BFRB and binge eating episodes. Several authors have suggested that shame plays an important role in the precipitation and maintenance of these impulsive behaviors. Further, the physical shame and the consequences associated with these behaviors contribute to propelling a “cycle of shame”. To this day, many of the cognitive processes used to characterizing these conditions remain unexplored, including cognitive emotion regulation strategies and self-criticism (i.e., harmful and punitive self-assessment). The investigation of these cognitive processes and shame will contribute to refining existing models. Moreover, studying BFRBs and EDs simultaneously allows us to compare the diverging and converging processes between these often-comorbid conditions. The first article presented within the framework of this thesis aims to identify the relationship between BFRB and ED symptom-severity, self-criticism, shame, and maladaptive cognitive emotion regulation strategies. More exploratory in nature, this study was conducted with an online sample of adults from the community using self-reported questionnaires. The results demonstrate a positive correlation between BFRB and ED symptoms, along with the other processes studied. Additionally, shame and maladaptive emotional regulation strategies partly explained BFRB symptom severity, whereas self-criticism explained ED symptom severity. The second article of this thesis aims to evaluate the impact of shame on the urge to engage in episodes of BFRBs and binge eating. This experimental study was carried out with three groups of women, namely a control group (n = 18), a BFRB group (n = 18), and a group of people suffering from an ED involving binge eating behaviors (n = 18). Findings confirmed that shame increases the urge to engage in BFRBs, but not the urge to engage in binge eating. Moreover, results highlighted the persistence of feelings of shame following BFRB and binge eating episodes. Findings from this study underline the importance of shame as a precipitating factor to BFRB episodes, as well as a maintenance factor to BFRBs and binge eating. Compared to the control group, the BFRB and binge eating groups demonstrated increased sensitivity to shame. Overall, the results of the present thesis support the role of shame in BFRB symptoms severity, as well as a trigger and maintenance factor for BFRB episodes. In addition to discussing the results of this thesis, its main limitations and strengths will be presented in the discussion. The theoretical and clinical implications, as well as perspectives for future research will also be discussed.
