Expert Panel Recommends Questionnaire to Help Spot Depression
Form could be filled out during visit to family doctor, and patient could be referred for follow-up care
By Dennis Thompson
MONDAY, July 27, 2015 (HealthDay News) -- Part of your next visit to your family doctor's office should be spent filling out a questionnaire to assess whether you're suffering from depression, an influential panel of preventive medicine experts recommends.
What's more, people concerned that they might be depressed could download an appropriate questionnaire online, fill it out ahead of time and hand it over to their doctor for evaluation, the panel added.
In an updated recommendation released Monday, the U.S. Preventive Services Task Force urged that family doctors regularly screen patients for depression, using standardized questionnaires that detect warning signs of the mental disorder.
If a patient shows signs of depression, they would be referred to a specialist for a full-fledged diagnosis and treatment using medication, therapy or a combination of the two, according to the recommendation.
These questionnaires can be self-administered in a matter of minutes, with doctors reviewing the results after patients fill out the forms, said Dr. Kirsten Bibbins-Domingo, vice chair of the task force.
"This could be a checklist that patients fill out in the waiting room, or at home prior to the visit," she said. "The good thing is we have many instruments, measures that have been studied for screening for depression."
About 7 percent of adults in the United States currently suffer from depression, but only half have been diagnosed with the condition, said Bibbins-Domingo, who is a professor of medicine, epidemiology and biostatistics at the University of California, San Francisco.
"We know that depression itself is a source of poor health," she said. "It leads people to miss work, to not function as fully as they might, and we know it is linked and associated with other types of chronic diseases."
It makes sense that family doctors perform front-line screening for depression, since they are more likely than a mental health professional to come across a person with undetected symptoms, said Michael Yapko, a clinical psychologist and internationally recognized depression expert based in Fallbrook, Calif.
"Only about 25 percent of depression sufferers seek out professional help, but more than 90 percent will see a physician and present symptoms and signs that could be diagnosed," said Yapko, who is not on the task force.
The panel has recommended regular depression screening for adults since 2002, but their guidelines currently urge doctors to ask two specific questions that provide a quick evaluation of a person's mood. The questions are, "Over the past two weeks, have you felt down, depressed, or hopeless?" and "Over the past two weeks, have you felt little interest or pleasure in doing things?"
The updated recommendation expands doctors' options for depression screening, adding commonly used questionnaires like the Patient Health Questionnaire, or PHQ-9.
The PHQ-9 is a list of 10 questions that focus on problems that a person might have experienced during the past two weeks, including poor appetite, low energy, sleep problems and a lack of interest in doing things.
"These are not instruments that diagnose depression," Bibbins-Domingo noted. "They give clinicians the first indication of something that should be followed up on."
Yapko said that someone who wanted to could lie on the questionnaires and avoid having their symptoms detected, but he added that in his experience it's not a very likely scenario.
"When you have people who are suffering who genuinely want help, they're happy to give you as accurate a portrayal as they can give you," he said. "Generally speaking, the people seeking help want help and they want to do their best in filling these things out. That's what makes the test worthwhile."
The task force is an independent, volunteer panel of national experts that has been issuing recommendations on preventive medicine since 1984.
Yapko and Bibbins-Domingo said depression screening shouldn't eat into a doctor's time, since patients can fill out and score the questionnaires on their own.
Instead of wasting time reading magazines in the waiting room, patients "could be filling out an inventory that is self-administered, self-scored and wouldn't take any physician time at all," Yapko said.
Patients also could download and fill out a depression questionnaire at home and hand it in when they go to the doctor, but Yapko said patients should make sure they're using the form their doctor prefers.
"Which of the many inventories and questionnaires a doctor might wish to use is a matter of personal and professional judgment," he said. "So, a doctor would need to specify which form to obtain online and the patient would then need to remember to bring it in, not always easy when depression negatively affects your memory. Easier to have the form in the office and have them fill it out in the waiting room."
Yapko added that it's important that doctors who screen for depression follow up by referring patients to a mental health professional, rather than trying to diagnose and treat depression themselves.
"When physicians get a diagnosis of depression, their most immediate thing to do is prescribe an antidepressant," Yapko said, noting that more than 70 percent of antidepressants are prescribed by non-psychiatrists. "Only a minority of people walk out of a doctor's office with a referral to a mental health professional, a fact which drives me a little crazy."
