Intolerance of Uncertainty and Eating Disorder Symptoms Over the Course of Intensive Treatment

Development and Validation of a Broad and Fear-Adaptable Measure of Fear Approach and Application to Common Eating Disorder Fears

Fear approach is a theorized mechanism of exposure treatment for anxiety-based disorders. However, there are no empirically established self-report instruments measuring the tendency to approach feared stimuli. Because clinical fears are heterogeneous, it is important to create a measure that is adaptable to person- or disorder-specific fears. The current study (N = 455) tests the development, factor structure, and psychometric properties of a self-report instrument of fear approach broadly and the adaptability of this measure to specific eating disorder fears (i.e., food, weight gain). Factor analyses identified a unidimensional, nine-item factor structure as the best fitting model. This measure had good convergent, divergent, and incremental validity and good internal consistency. The eating disorder adaptations retained good fit and strong psychometric properties. These results suggest that this measure is a valid, reliable, and adaptable measure of fear approach, which can be used in research and exposure therapy treatment for anxiety-based disorders.

Relationship between Fear of COVID-19, Intolerance of Uncertainty, and Coping Strategies on University Students' Mental Health

BACKGROUND

the mental health of students was particularly affected by the COVID-19 pandemic. The present study therefore examined the relationships between anxiety and depressive symptoms, eating-related problems, coping, fear of COVID-19, and intolerance of uncertainty.

METHODS

2139 French students of 54 universities were recruited in the different regions of France during a French lockdown (between 21 April and 3 May 2021). Six variables were measured: fear of COVID-19, intolerance of uncertainty, coping, anxiety and depressive symptoms, and eating-related problems. To explore the directions of the relationships between our variables of interest, we calculated a directed acyclic graph.

RESULTS

our data highlighted the central roles of intolerance of uncertainty in students' anxiety and depressive symptoms, and the direct role of prospective intolerance of uncertainty on eating-related problems.

CONCLUSIONS

these findings indicate that intolerance of uncertainty should be targeted by interventions designed to help students with high levels of anxiety, depressive symptoms, and/or eating-related problems.

Broad and Narrow Transdiagnostic Risk Factors in Eating Disorders: A Preliminary Study on an Italian Clinical Sample

Eating disorders are multifaceted psychopathologies and the transdiagnostic approach is currently considered a useful framework to understand their complexity. This preliminary study aimed to investigate both broad (i.e., intolerance of uncertainty and emotion dysregulation) and narrow (i.e., extreme body dissatisfaction) transdiagnostic risk factors underlying eating disorders. 50 Italian female patients seeking treatment for an eating disorder were involved (M_age = 31.6 years ± 12.8, 18–65). They completed self-report measures assessing emotion regulation difficulties, intolerance of uncertainty, extreme body dissatisfaction, general psychological distress, and eating disorder symptomatology. To explore whether the abovementioned transdiagnostic factors predicted patients’ psychological distress and eating disorder symptoms, two linear regressions were performed. Emotion dysregulation emerged as the only significant predictor of distress, while extreme body dissatisfaction was the only significant predictor of overall eating disorder symptomatology. Then, to analyze the differences between patients with anorexia nervosa and bulimia nervosa in intolerance of uncertainty and emotion regulation problems, t-tests were conducted. The two groups differed significantly in intolerance of uncertainty levels only, with higher scores obtained by patients with anorexia nervosa. Overall, our findings suggest that emotion dysregulation and extreme body dissatisfaction may be relevant constructs in eating disorders in general, while intolerance of uncertainty may be more involved in restrictive eating disorders. The clinical implications of such results are discussed.

Psychosocial correlates of body esteem and disordered eating among sexual minority adolescent girls

The present study examined whether body esteem mediates the associations between psychosocial factors, including peer victimization and parent-adolescent relationship quality, and multiple categories of disordered eating (DE) within a diverse sample of adolescent sexual minority (SM) girls. Participants were 528 girls, aged 14-18 years, recruited as part of a larger online study on LGBTQ + adolescent health. Participants anonymously completed self-report measures of parent-adolescent relationship quality, sexual orientation-based victimization, body esteem, and DE behaviors, including binge eating, purging, and caloric restriction. Parent-adolescent relationship quality was positively associated with SM adolescent girls' body esteem, and some aspects of body esteem subsequently mediated the associations between parent-adolescent relationship quality and DE behaviors. Experiences of sexual orientation-related victimization were also positively related to endorsement of caloric restriction. However, no significant indirect effects were observed between sexual orientation-related victimization and DE via body esteem. These results suggest parents could influence their SM daughters' DE behaviors via body esteem, and SM girls may be engaging in caloric restriction if they experience victimization, regardless of their body esteem.
