Watch out! A path from anxiety to anorexia nervosa through biased attention?

OBJECTIVE: Evidence points towards heightened anxiety and attention biases (AB) towards disorder-specific (threatening) stimuli in patients with anorexia nervosa (AN). To date, it is unclear how anxiety and AB interact in eating disorders (ED). The present study tests the causal role of anxiety by inducing anxiety before a dot-probe task with either ED-specific stimuli or unspecific negative (threat-related) information. We expected that anxiety would elicit AB for ED-specific, but not for unspecific threat-related stimuli. METHODS: Adolescents with AN (AN, n = 32) or depression (DEP, n = 27) and healthy controls (HC, n = 29) underwent an anxiety induction or a low anxiety control task before a pictorial dot-probe task with either under-/overweight body-related pictures or non-disorder-related threatening pictures (angry faces). BMI, level of ED symptoms, anxiety, stress, and depression were assessed at baseline. RESULTS: The anxiety induction did not affect the observed attention pattern. AN showed an AB towards underweight body pictures compared to HC, whereas no disorder-unspecific threat-related AB emerged. Regression analyses revealed that only anxiety predicted the AB towards underweight body pictures. DISCUSSION: Further experimental research may integrate eye tracking as an additional tool, or collect information on body dissatisfaction to obtain a better understanding of how anxiety biases attention.

I C U but I don't care: Callous-unemotional traits and approach-avoidance behaviour in conduct disorder.

BACKGROUND AND OBJECTIVES: Conduct disorder (CD) is associated with deficits in social-emotional behaviour, such as increased levels of aggression. Callous-unemotional (CU-) traits foster those deficits and contribute to severe rates of instrumental aggression in CD. Previous studies of that increase in aggression have mainly focused on intentional aspects of behaviour. Unintentional behaviour, such as automatic approach and avoidance, has not been taken into account despite being highly relevant for behaviour. Therefore, the relevance of CU-traits for automatic actions and the feasibility of an approach-avoidance-task to measure those actions in CD-patients were investigated in a study series. METHODS: Study 1 22 CD-patients executed an approach-avoidance task, where participants pushed or pulled pictures of emotional faces using a joystick. CU-traits were assessed via parent-report. Study 2 28 CD-patients and 19 typically developing children (TD) executed the AAT. Again, CU-traits were assessed via parent-report. RESULTS: The AAT was a feasible instrument to measure automatic action tendencies and revealed that, while TD-children showed an avoidance bias towards angry faces, CD-patients showed a lack of automatic avoidance of anger. Across the whole sample (TD and CD combined), CU-traits predicted less threat avoidance. LIMITATIONS: The small sample size may have limited the power to detect smaller approach-avoidance tendencies towards other emotions. CONCLUSIONS: The findings suggest that CD is associated with a lack of automatic avoidance of social threat and that CU-traits predict that lack of avoidance. Divergent automatic threat responding might underlie the extreme levels of instrumentally aggressive behaviour observed in CD-patients with distinctive CU-traits.

The Mediating Effect of Specific Social Anxiety Facets on Body Checking and Avoidance.

Objective: Body checking (BC) and avoidance (BA) form the behavioral component of body image disturbance. High levels of BC/BA have often been documented to hold a positive and potentially reinforcing relationship with eating pathology. While some researchers hypothesize, that patients engage in BC/BA to prevent or reduce levels of anxiety, little is known about the mediating factors. Considering the great comorbidity between eating disorders (ED) and in particular social anxieties, the present study investigated whether socially relevant types of anxiety mediate the relationship between eating pathology and BC/BA. Methods: 83 participants reporting an eating disorder and 323 healthy participants (14-25 years) took part in an online survey. Eating pathology was measured with the Eating Disorder Examination Questionnaire and Body Checking and Avoidance Questionnaire. Trait and social anxiety were assessed by means of the State Trait Anxiety Inventory (STAI-T), the Fear of Negative Evaluation (FNE) and the Social Appearance and Anxiety Scale (SAAS). Separate mediation analyses were carried out with eating pathology as independent variable, BC/BA as dependent variable and STAI, FNE, and SAAS as mediating variables. Results: Anxieties correlated highly positive with eating pathology in both groups. SAAS mediated the relationship between ED pathology and BC/BA in participants with ED and mediated the relationship between ED pathology and BA in healthy participants. FNE mediated the relationship between eating pathology and BA for participants with eating pathology. Discussion: SAAS mediated the relationship between eating pathology and BC/BA. Being afraid of bodily evaluations may represent a particular relevant fear that triggers safety behaviors.
