BackgroundThe DSM-IV symptom criteria for major depressive disorder (MDD) are somewhat lengthy, with many studies showing that treatment providers have difficulty recalling all nine symptoms. Moreover, the criteria include somatic symptoms that are difficult to apply in patients with medical illnesses. In a previous report, we developed a briefer definition of MDD that was composed of the mood and cognitive symptoms of the DSM-IV criteria, and found high levels of agreement between the simplified and full DSM-IV definitions. The goal of the present study was to replicate these findings in another large sample of psychiatric out-patients and to extend the findings to other patient samples.MethodWe interviewed 1100 psychiatric out-patients and 210 pathological gamblers presenting for treatment and 1200 candidates for bariatric surgery. All patients were interviewed by a diagnostic rater who administered a semi-structured interview. We inquired about all symptoms of depression for all patients.ResultsIn all three samples high levels of agreement were found between the DSM-IV and the simpler definition of MDD. Summing across all 2510 patients, the level of agreement between the two definitions was 95.5% and the κ coefficient was 0.87.ConclusionsAfter eliminating the four somatic criteria from the DSM-IV definition of MDD, a high level of concordance was found between this simpler definition and the original DSM-IV classification. This new definition offers two advantages over the current DSM-IV definition – it is briefer and it is easier to apply with medically ill patients because it is free of somatic symptoms.

AbstractMajor depressive disorder (MDD) and migraine are both more common among women than men. Women’s reproductive years are associated with increased susceptibility to recurrence of both conditions, suggesting a potential role of sex hormones in aetiology. We examined associations between comorbid migraine and clinical features of MDD in women, including relationships with lifetime reproductive events such as childbirth. Lifetime clinical characteristics and reproductive events in a well-characterised sample of 222 UK women with recurrent MDD, with (n = 98) and without (n = 124) migraine were compared. Women had all been recruited as part of a UK-based ongoing programme of research into the genetic and non-genetic determinants of mood disorders. Multivariate analysis showed a specific association between the lifetime presence of migraine and postpartum depression (PPD) within 6 weeks of delivery (OR = 2.555; 95% CI: 1.037–6.295, p = 0.041). This association did not extend to a broader definition of PPD with onset up to 6 months postpartum. All other factors included in the analysis were not significantly associated with the presence of migraine: family history of depression, younger age at depression onset, history of suicide attempt and severe premenstrual syndrome symptoms. The finding that women with MDD and comorbid migraine may be particularly sensitive to hormonal changes early in the postpartum period leads to aetiological hypotheses and suggests this group may be useful for future studies attempting to characterise PPD and MDD phenotypes. The refinement of such phenotypes has implications for individualising risk and treatment and for future biological and genetic studies.

BACKGROUND Diagnosing major depressive disorder (MDD) is challenging, with diagnostic manuals failing to capture the wide range of clinical symptoms that are endorsed by individuals with the condition. OBJECTIVE The aim of this study was to provide evidence for an extended definition of MDD symptomatology. METHODS Symptom data were collected via a digital assessment that was developed for the Delta Study [1]. Random forest classification with nested cross-validation was used to distinguish between individuals with MDD and those with subthreshold symptomatology of the disorder using i) disorder-specific symptoms and ii) transdiagnostic symptoms. The diagnostic performance of the Patient Health Questionnaire-9 (PHQ-9) was also examined. RESULTS A depression-specific model demonstrated good predictive performance when distinguishing between individuals with MDD (n = 64) and those with subthreshold depression (n = 140) (AUC = .89; sensitivity = 82.4%; specificity = 81.3%; accuracy = 81.6%). The inclusion of transdiagnostic symptoms of psychopathology, including symptoms of depression, generalized anxiety disorder, insomnia, emotional instability, and panic disorder, improved the model performance (AUC = .95; sensitivity = 86.5%; specificity = 90.8%; accuracy = 89.5%). The PHQ-9 was excellent at identifying MDD but over diagnosed the condition (sensitivity = 92.2%; specificity = 54.3%; accuracy = 66.2%). CONCLUSIONS Our findings are in line with the notion that current diagnostic practices may present an overly narrow conception of mental health. Further, our study provides proof-of-concept support for the clinical utility of a digital assessment to inform clinical decision-making in the evaluation of MDD.
