TL;DR: An IRT-based instrument-independent metric for depression severity enables direct comparisons among established measures and simplifies the interpretation of depression assessment by identifying key thresholds for clinical and epidemiologic decision making and facilitates integrative psychometric research across studies, including meta-analysis.

TL;DR: Comparing the validity and clinical utility of current and several new diagnostic proposals of those somatoform disorders that focus on medically unexplained somatic symptoms suggests that, of all current and new diagnostic suggestions, complex somatic symptom disorder and the CISSD definition appear to have advantages regarding validity andclinical utility.

TL;DR: Psychological symptoms enhance predictive validity and clinical utility of DSM-5 Somatic Symptom Disorder compared to DSM-IV somatoform disorders and identifies more psychologically impaired patients than its DSM- IV precursor.

TL;DR: Psychological symptoms appear to be predictively valid diagnostic criteria for the 12-month functional outcome in patients with SSD and mental functioning can be better predicted by the DSM-5 diagnosis than by DSM-IV diagnoses.

TL;DR: The SSEQ appears to be a reliable, valid, and efficient instrument to assess a broad range of psychological and interactional features related to the experience of somatic symptoms.
