Personnel and Training Required
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.
The PhenX Working Group acknowledges that these questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil 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.
|Average time of greater than 15 minutes in an unaffected individual||No|
|Specialized requirements for biospecimen collection||No|
Mode of Administration
These questions may be part of a self-administered or interviewer-administered questionnaire.
However, several studies have indicated different results between interviewer and self-report administrations within the same samples. Therefore, caution should be used in comparison to previously published samples. It may be advisable, such as in epidemiologic studies, to employ a two-step procedure combining self-report with follow-up interview-based administration.
Answers in bold indicate depression. Score 1 point for each bolded answer. A score greater than 5 points is suggestive of depression and should warrant a follow-up comprehensive assessment. A score greater than or equal to 10 points is almost always indicative of clinically significant depression.
Prorating Scores (What to do if a patient misses a couple items).
If, say, 3 of 15 items are missed, and the total score is 4 on the 12 completed items, add 4/12 of the 3 missing points (i.e., 1 point) to the score. The total score would be 4+1 = 5.
In other words, we are solving the equation 4/12 = X/15, so X = 5.

A self-report questionnaire to assess symptoms of major depressive disorder (MDD).
This measure can be used to rapidly assess depressive symptoms and select cases and non-cases. Depression is a common disorder that demonstrates a familial pattern and is comorbid with other psychiatric disorders, including anxiety disorder, substance use disorders, and eating disorders. Additionally, certain medical conditions-such as diabetes, stroke, and heart disease-can increase the risk of depression. Some individuals who present with major depressive episodes may have a bipolar spectrum disorder.
The Geriatric Depression Scale is a validated, widely distributed, and easy-to-complete questionnaire that can be finished in approximately 5 to 7 minutes.
