- Adolescence has been considered a critical time for the development of body image-related difficulties and disordered eating behaviours, especially in females. Although adherence to eating rules has been linked to disordered eating, literature has not yet explored how the inflexible subscription to those rules impacts on eating psychopathology. Therefore, the aim of the current study was to explore whether inflexible eating impacts on the relationships between weight and body image-related variables, and disordered eating.Participated in this study are 497 female adolescents from the community, aged between 14 and 18 years old, who completed self-report measures.Results revealed that the majority of the participants were dissatisfied with their weight and body shape. Moreover, 6.64 % of the participants demonstrated severe eating psychopathology. A path analysis revealed that BMI, body dissatisfaction and social comparisons based on physical appearance impact on disordered eating behaviours, through the mechanism of inflexible adherence to eating rules. This model explained 52 % of eating psychopathology's variance.Findings highlight the relevance of body image-related difficulties in adolescence and additionally they emphasise the importance of promoting more flexible attitudes towards eating in prevention and intervention programmes with female adolescents.

- Restrictive dieting is an increasing behavior presented by women in modern societies, independently of their weight. There are several known factors that motivate diet, namely a sense of dissatisfaction with one's body and unfavorable social comparisons based on physical appearance. However, dieting seems to have a paradoxical effect and has been considered a risk factor for weight gain and obesity in women and for maladaptive eating. Nevertheless, the study of the emotional regulation processes that explain the adoption of inflexible and rigid eating behaviors still remains little explored. In this line, the present study aims to explore why normal-weight women engage in highly rigid and inflexible diets. We hypothesize that body and weight dissatisfaction and unfavorable social comparisons based on physical appearance explain the adoption of inflexible eating rules, through the mechanisms of body image inflexibility. The current study comprised 508 normal-weight female college students. Path analyses were conducted to explore the study's hypotheses. Results revealed that the model explained 43 % of inflexible eating and revealed excellent fit indices. Furthermore, the unwillingness to experience unwanted events related to body image (body image inflexibility) mediated the impact of body dissatisfaction and unfavorable social comparisons on the adoption of inflexible eating rules. This study highlights the relevance of body image inflexibility to explain rigid eating attitudes, and it seems to be an important avenue for the development of interventions focusing on the promotion of adaptive attitudes towards body image and eating in young women.

- Literature has demonstrated the negative impact of body image dissatisfaction on women's quality of life. Nonetheless, it has been suggested that the relationship between body dissatisfaction and women's well-being is not linear, and that the processes that mediate this association remain unclear. This study aims to clarify the mediator role of self-judgment in the association between negative body image and psychological quality of life, in two groups: normal-weight and overweight women. This cross-sectional study comprised 200 normal-weight and 92 overweight female college students, aged between 18 and 24 years old, that completed self-report instruments of body dissatisfaction, self-judgment, and quality of life. Results showed that women who presented harsher self-judgment about their perceived failures tended to present lower levels in all quality of life domains. Also, results from mediation analyses indicated the relationship between body dissatisfaction and psychological quality of life was significantly mediated by the mechanisms of self-judgment in the two BMI groups (95% CI [-2.41 to -0.04]; 95% CI [-6.35 to -.89]). This mediational model accounted for 28.3% and 40.7% of psychological quality of life in the normal-weight and overweight groups, respectively. These results suggest that a lower ability to deal with one's failures or inadequacies (e.g., negative evaluation of body image) in a kind and accepting manner may significantly increase the negative impact of body dissatisfaction on one's psychological quality of life. In this way, it seems that, the focus of interventions should go beyond body dissatisfaction and also target the development of adaptive attitudes (opposed to self-critical attitudes) to deal with negative body-related experiences.

- The Engaged Living Scale (ELS) is a measure of the process of engaged living, defined by Acceptance and Commitment Therapy as the evaluation and performance of valued life activities. This 16-item measure was recently created and has been validated in middle-aged and chronic pain samples. The aim of the present study was to validate the ELS-16 in a young-adult sample and additionally to develop a shorter ELS. This study was conducted using different samples of Portuguese young-adult college students. The dimensionality of the ELS-16 (which was translated to Portuguese from the original Dutch) was tested through a CFA. The adequacy of the shorter ELS (ELS-9) was also tested through a CFA. The scales' internal reliability and other psychometric qualities were additionally analysed. Results from the CFA suggested that the model benefits from the establishment of correlations between pairs of error terms of items with similar contents. These results led to the decision to shorten the measure by excluding the item of each pair with the lowest communalities. The ELS-9 was then created and its CFA results revealed good to excellent adjustment values and goodness-of-fit indices. Results also showed that the ELS-16 and the ELS-9 present adequate to good psychometric properties. The present study thus shows that these instruments seem to be reliable measures of engaged living and to perform adequately in young-adult college students, with the ELS-9 being a new contribution to health research and allowing faster administrations.

- This study aimed to test the effects of inflammatory bowel disease symptomatology and associated medical complications on physical and psychological quality of life and to explore whether these relationships are mediated by experiential avoidance. A total of 200 inflammatory bowel disease patients reported demographic and medical data and completed self-report instruments. Results revealed that the tested model presented an excellent fit, explaining 51 per cent of physical quality of life and 53 per cent of psychological quality of life. Inflammatory bowel disease-associated complications directly impacted on physical quality of life, and experiential avoidance significantly mediated the relationships between inflammatory bowel disease symptomatology and physical and psychological quality of life. These results highlight the importance of implementing psychological interventions for inflammatory bowel disease patients.
