Multidimensional self reports as a measure of characteristics in people with eating disorders.
This study used multidimensional self report assessments to measure perfectionism, impulsivity and obsessive compulsive characteristics in females with anorexia nervosa (AN), bulimia nervosa (BN) and in matched healthy controls (HC). The Frost Multidimensional Perfectionism Scale (FMPS), Barrett Impulsivity Scale (BIS) and Obsessive Compulsive Inventory-Revised (OCI-R) scale were completed by 107 participants (AN=30, BN=26, HC=51), in parallel with clinical measures. Results show that people with AN have the highest scores on the dimensions of the FMPS as well as on the overall score; the AN and BN groups have the highest scores on the dimensions and on the overall score of the OCI-R; on the BIS, the AN and BN groups have the highest scores on the attention subscale, but there are no group differences on the overall BIS scores. In relation to the FMPS, the global score, and the subscales 'concern over mistakes' and 'doubts about actions' are all highly correlated with both eating pathology (Eating Disorder Examination Questionnaire, EDE-Q) and low global functioning (Structured Clinical Interview for DSM IV, SCID). The subscale 'obsessing' on the OCI-R shows a strong correlation with eating pathology. The overall score and also the subscales of the BIS do not show strong correlations with eating pathology or poor global functioning. In conclusion, therapies should seek to address these specific areas which are highly correlated with eating disorder pathology.
