Abstract

In a clinical sample of 198 female patients with anorexia nervosa (N=83) and bulimia nervosa (N=115), 43% met criteria for major depression using the Structured Clinical Interview for DSMIII-R. This group had a mean score of 30.9±8.7 on the Beck Depression Inventory (BDI) which was significantly higher than the BDI mean score of 20.5±8.9 among the remainder of the sample (p<0.0001). A score of 26 yielded the highest levels of sensitivity and specificity, while five items from the BDI (loss of satisfaction, discouragement, weight loss, suicidal ideation and decision-making) correctly classified approximately 80% of subjects into “depression-positive” or “depression-negative” categories. Detection of co-morbid depression in patients with eating disorders may have practical implications for treatment.

      We used the MINI to assess lifetime suicidal behaviors and to calculate a suicidality score. In order to estimate the number of subjects to be included, and the required proportion of patients with BPD in the confirmatory sample, we initially defined a required sensitivity and specificity over 0.75, as did Kennedy et al. (1994) searching for a relevant instrument to detect major depressive disorder co-morbidity in AN [22]. With an expected prevalence of 19.33% of BPD in patients with AN found in the pilot sample, an α risk of 5%, a 1-β power of 80% and a 1-γ threshold of 25%, we computed that to get an informative PPV [23], 56 patients or more should be included, with a proportion above 25% of patients having BPD.

      It is also noteworthy that few of the included studies account for the potential impact of co-morbid disorders on neuropsychological performance. Especially since AN is commonly associated with other psychiatric disorders, such as anxiety and/or depression (Kaye et al., 2004; Kennedy et al., 1994). In fact, most studies (m = 35) neither assess nor report the number of participants with a co-morbid Axis I diagnosis.

      Furthermore, for assessing depression, not only were the scales diverse among the studies, but also the cut-off scores used were not always reported. The BDI was frequently used: for example Meehan et al. (Meehan et al., 2006) used a score of 13 and above to be indicative of depression, while in 1994, Kennedy et al. questioned the predictive power of the BDI in AN and proposed that a score of 26 produced optimal results in terms of specificity and sensitivity (Kennedy et al., 1994). At this point, different interpretations of the psychological status of the patients are highlighted.
