Depression - Adult #120502
Protocol Release Date
  May 12, 2010 Protocol Name From Source
The Expert Review Panel has not reviewed this measure yet. Description of Protocol
This protocol is divided into two parts. Part I consists of the depression section from the Composite International Diagnostic Interview - Short Form (CIDI-SF), developed for the World Health Organization, and is a screening tool for the general population. Part II consists of the Quick Inventory of Depressive Symptoms (QIDS) that captures the severity of depressive symptoms in the last seven days. Specific Instructions
The screening protocol included in Part I should be completed on all participants. Part II should be completed on participants that screen positively for depression to provide additional specificity about underlying symptoms. The Psychiatric Working Group has recommended that the portions of the Composite International Diagnostic Interview - Short Form (CIDI-SF) be used separately to screen for specific disorders in the PhenX Toolkit. Specifically, the entire instrument is included as the PhenX Measure General Psychiatric Assessment, section A is included as a protocol for the PhenX Measure of Depression, section I is included as a protocol for the PhenX Measure of Obsessive Compulsive Disorders, and sections B, C, D, E and F are included as a protocol Anxiety Disorders. Therefore, selecting the General Psychiatric Assessment measure in combination with Depression, Obsessive Compulsive Disorder and / or Anxiety Disorders will result in selecting the same protocol multiple times. Contained in these instruments are questions about thoughts of suicide. If using these protocols, please inform your Institutional Review Boards of these questions and institute a plan of action for dealing with suicidal thoughts in your respondent. It may be necessary to create a separate protocol for immediate action and/or referral. Protocol

Selection Rationale
The Composite International Diagnostic Interview - Short Form (CIDI-SF) was selected to screen a general populations for the presence of depression because it has been used on thousands of subjects in the US and around the world, is available in multiple formats, is easily administered by trained non-clinician interviewers, is well validated and provides screening criteria consistent with the International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) and Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV). The Quick Inventory of Depressive Symptoms (QIDS) was selected to provide additional specificity about the underlying symptoms of those participants that screen positively for depression. The Quick Inventory of Depressive Symptoms (QIDS) was vetted against several other dimensional measures for depression and ultimately selected because it is free, easily administered as a self-reported instrument for ages 12 and above and captures the general symptoms of depression.

The Composite International Diagnostic Index - Short Form can be used for adults age 18 or older. The Quick Inventory of Depressive Symptoms can be used as a self report for age 12 through adult. Personnel and Training Required
Composite International Diagnostic Index - Short Form: The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews*. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided. * There are multiple modes to administer this question (e.g., pencil and paper and computer-assisted interviews). Quick Inventory of Depressive Symptoms: No training or personnel required for self-administered questionnaire. Equipment Needs
While the source protocol for the Composite International Diagnostic Index - Short Form was developed to be administered by a computer-assisted instrument, the PhenX Psychiatric Working Group acknowledges these questions can be administered in a non-computerized format (i.e. pencil and paper instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire. Quick Inventory of Depressive Symptoms No equipment is necessary for a self-administered questionnaire. Standards
