May 15, 2019 updated by: Jonathan W Stewart, M.D, New York State Psychiatric Institute

Dichotic Listening as a Predictor of Placebo and Medication Response in Depression

Depressed patients will have hearing tests and then be treated with up to three treatments (i.e., Fluoxetine, Imipramine) until remitted, to see whether test results predict specific outcomes.

Detailed Description

100 depressed patients will be tested with verbal and nonverbal dichotic tests, and then treated sequentially with Fluoxetine and Imipramine until remitted. Preferential hemisphere for auditory processing will be correlated with treatment outcome.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hamilton Depression Scale (HAM-D)
Time Frame: 6 weeks
The HAM-D is a commonly used measure of the severity of depression. While several versions exist consisting of different numbers of items, virtually all include the original 17. Each item is scored from on a 3 or 5 point scale (so, from 0-2 or 0-4), with 0 indicating the item is not present and the highest item score indicating it is present nearly all the time to the severest extent. Item scores are added to obtain a total HAM-D score. Minimum possible score is 0 (indicating none of the 17 items is present), maximal possible score is 52. By convention, scores of <=7 are accepted as indicating "remission" and scores that have decreased >= 50% from pre-treatment indicate positive "response". Higher scores indicate worse depression, while lower scores indicate milder depression or lack of depressive symptoms.
6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Positive Response as Assessed by the Clinical Global Impression -Global Improvement Scale (CGI-I)
Time Frame: 6 weeks.
The CGI consists of two ratings: 1) Global Severity (CGI-S) and 2) Global Improvement (CGI-I), both having seven possible ratings, each from 1-7. Ratings on the CGI-S are: 1="No psychopathology" 2="Minimal psychopathology" 3="Mild psychopathology 4="Moderate psychopathology" 5="Moderately severe psychopathology" 6="Severe psychopathology" 7 "Extreme psychopathology". CGI-I ratings are rated for how the past week's psychopathology compares to the week immediately prior to start of treatment and includes: 1="Very much improved" 2="much improved" 3="minimally improved" 4="Unchanged" 5="minimally worse" 6="much worse" 7="very much worse". Scores on both thus range from 1-7 with lower scores indicating less psychopathology/greater improvement, respectively, and higher scores indicating more psychopathology/less improvement, respectively. We define "response" as a CGI-I of 1 or 2; "nonresponse" is all other ratings (i.e., CGI-I = 3 or higher.
