Predictors and Moderators of Time to Remission of Major Depression with Interpersonal Psychotherapy and SSRI Pharmacotherapy Ellen Frank, PhD Distinguished Professor of Psychiatry University of Pittsburgh School of Medicine OVERVIEW • Rationale and Aims of the Depression Phenotypes Study • The Spectrum Psychopathology Concept • Early Studies of Spectrum Psychopathology as Predictors of Treatment Response • Depression Phenotypes Study Design and Outcomes Rationale and Aims of the Depression Phenotypes Study Depression: The Search for Treatment Relevant Phenotypes - Study Rationale and Aims • To define a set of indicators and corresponding assessment instruments that show a strong, consistent and clinically significant association with depression treatment outcome with pharmacotherapy vs. psychotherapy • Potential indicators studied: 1) type and number of mood spectrum features 2) type and number of anxiety spectrum features 3) treatment exposure – to both SSRI and IPT 4) demographic and clinical characteristics The Spectrum Psychopathology Concept THE PISA-PITTSBURGH SPECTRUM CONCEPT EVOLVED FROM CASSANO’S SEMINAL OBSERVATIONS Patients who meet criteria for a DSM disorder often manifest a spectrum of related symptoms, behavioral tendencies and temperament traits, not included in the diagnostic criteria. Recognition of these clinically significant features can improve the doctor-patient relationship, identify clinically meaningful subtypes, and guide treatment decisions. Cassano GB, et. al. AJP 1997; 154(suppl 6):27-38 THE PISA-PITTSBURGH SPECTRUM CONCEPT We assume that spectrum features may be present over the course of the lifetime, often as isolated phenomena even in those who do not currently meet or have never met the full criteria for the related syndrome. Associated features Typical Symptoms “Atypical “ Symptoms (i.e. not included in diagnostic Criteria) Behavioral Tendencies Features of Interpersonal Relationships SAB Clinical Observations of patients meeting criteria for a DSM IV Disorder www.spectrum-project.org • General description of spectrum concept • Downloadable copies of all instruments • Bibliography through 2006 ILLUSTRATING THE SPECTRUM APPROACH: PANIC-AGORAPHOBIC SPECTRUM • How an instrument was developed • Confirmation of reliability and validity • Establishing clinical significance PANIC-AGORAPHOBIC SPECTRUM 114 symptoms and related behavioral tendencies and temperament traits DOMAINS Separation sensitivity Panic-like symptoms Stress sensitivity Anxious expectation Medication/substance sensitivity Agoraphobic symptoms Illness phobia/hypochondriasis reassurance orientation Percentage of subjects DISTRIBUTION OF SCI-PAS SCORES IN PATIENTS WITH DSM IV PANIC DISORDER 30% 25% 20% 15% 10% 5% 0% 0-20 21 30 31 40 41 50 51 60 61 70 Total SCI-PAS Score 71 -80 81 90 91 100 Percentage of subjects 60% DISTRIBUTION OF SCI-PAS SCORES IN PATIENTS WITHOUT DSM IV PANIC DISORDER 50% 40% 30% 20% 10% 0% 0-20 21 - 30 31 - 40 41 - 50 51 - 60 61 - 70 71 -80 81 - 90 Total SCI-PAS Score 91 100 Early Studies of Spectrum Psychopathology as Predictors of Treatment Response POTENTIAL UTILITIES OF THE SPECTRUM APPROACH • improvement of the clinician-patient relationship • identification of clinically meaningful subtypes • treatment selection • monitoring course of illness or treatment • measurement of outcome • prevention RELATIONSHIP OF PANIC SPECTRUM TO RESPONSE TO ACUTE TREATMENT OF A MOOD DISORDER H1: The presence of panic-agoraphobic spectrum symptomatology is associated with significantly longer times to remission of acute mood episodes.

Summary • The MOODS and PAS factors provided good prediction of time to remission for both IPT and SSRI treatment. • A only one MOODS and one PAS factor moderated treatment response both study sites. • A monotherapy-followed-by-combination-fornon-remitters sequence leads to a high remission rate among outpatients with unipolar depression regardless of whether the sequence is begun with medication or psychotherapy. .
