Validation of clinical symptom IRT scores for diagnosis and severity assessment of common mental disorders

Abstract

INS-D and INS-G are short reliable, valid, and responsive measures that can be used for diagnostic and severity assessment of mood and anxiety disorders in outpatient care.

Testing the PROMIS ® Depression measures for monitoring depression in a clinical sample outside the US

“…This study was conducted as part of the Inventory of Depression and Anxiety Symptoms (INSAyD) project (Olariu et al, 2014), a prospective study designed to provide brief and easy-to-use tools for diagnosing and assessing severity of mood and anxiety disorders, based on DSM-IV-TR symptom criteria, in a sample of primary care and specialized mental health patients seeking help for active symptoms of mood or anxiety. Patients were invited to participate from October 2011 to February 2013.…”

“…The study protocol was approved by the Ethics committee of the IMIM (Institut Hospital del Mar d'Investigacions M ediques) and fulfills the mandates of the Declaration of Helsinki. More details are provided elsewhere (Olariu et al, 2014).…”

Change in functioning outcomes as a predictor of the course of depression: a 12-month longitudinal study

“…Patients were considered dropouts if they missed any follow-up appointment and could not be reached by phone after five attempts. Details on the study are provided elsewhere [33]…”

“…The sample was part of the Inventory of Depression and Anxiety Symptoms (INSAyD), [32,33]), project for studying tools for diagnosis and communication among healthcare professionals. INSAyD was an observational, prospective study (baseline, 1-, 3-and 12-month assessments) in a cohort of patients seeking help for affective distress recruited in three care levels: primary care, outpatient mental health centers, and acute psychiatric inpatient hospitals.…”

“…More recently, some research has proposed propose simpler one-item numerical rating scales of functioning, similar to those used in pain 6 assessment [30]. PRO scales have shown good reliability and concurrence with experts' ratings [31], as well as sensitivity to the course of symptoms [32,33]. Given its straightforwardness, PROs methodology might be more suitable for rapid assessment of functioning in nonpsychiatric services.…”
