HERNANDEZ-GUZMAN, Laura; CONTRERAS-VALDEZ, José Alfredo  and  FREYRE, Miguel-Ángel. Categories or dimensions? Towards a transdiagnostic treatment of eating psychopathology. Rev. Mex. de trastor. aliment [online]. 2019, vol.10, n.2, pp.232-245.  Epub Mar 14, 2022. ISSN 2007-1523.  https://doi.org/10.22201/fesi.20071523e.2019.2.561.

The purpose of this research was to contrast the categorial and dimensional approaches within the eating disorders area. Research on the eating problems categorical model reveals vast evidence against its validity: excessive comorbidity, inadequate coverage, diagnostic migration, residual categories, false positives and negatives, etc. The dimensional conceptualization of the eating psychopathology study would achieve more accurate findings by considering eating problems according to the degree in which they manifest, avoiding diagnostics based on arbitrary cut-off points and facilitating the analysis of eating psychopathology at early age, as well as following symptom evolution throughout development. Based on the dimensional model, transdiagnostic perspective has received empirical support, which endorses the use of the transdiagnostic treatment aimed to underlying psychological mechanisms, such as negative affect and emotional dysregulation.

Keywords : Transdiagnostic; Eating disorders; Diagnostic categories; Comorbidity.
