Cognitive Remediation and Emotion Skills Training (CREST), a brief social cognition intervention, was developed for inpatients with Anorexia Nervosa (AN). CREST was piloted and evaluated in 28 Anorexia Nervosa patients on a specialist eating disorder inpatient unit. Content analysis was employed to qualitatively explore patients' experience of the intervention. Results suggest that patients perceived CREST positively. Main themes identified were that patients' valued education regarding the function of emotions and found learning strategies to manage and express emotions helpful. The clinical and research implications are discussed.

Difficulties in executive functioning and emotional processing are reported in anorexia nervosa (AN). This case study describes the application of cognitive remediation and emotion skills training (CREST), an intervention that has been piloted in an inpatient eating disorders (EDs) unit. CREST is a 10-session treatment package, which primarily addresses emotion processing difficulties, one of the maintaining features of AN. The stages of CREST are described, which includes targeting thinking styles, recognizing emotions in the self and others, strategies to manage emotions, and practice of emotion expression. Clinical and self-report data collected before and after CREST indicate improvements in identifying emotions and using healthier emotion regulation strategies, alongside an increase in body mass index (BMI) and reduction in ED symptomatology. This case study provides preliminary evidence for the acceptability and effectiveness of CREST as a lowintensity intervention before proceeding to more comprehensive therapies, such as cognitive behavior therapy to address the ED more fully.
