Clinical Studies for Depression

Many people who suffer from depression consider becoming involved in a research study. First you must understand the different types of research studies available to people who decide to volunteer.

Clinical studies are broadly classified as clinical trials and observational studies. If you know the difference, you’ll be more informed and more capable of making a decision.

Clinical trials

Clinical trials, also known as interventional studies, are created with the goal of providing specific interventions to the participants of the study. These interventions follow a rigorous protocol created by the research team and may include drugs, medical devices, procedures like MRI, or lifestyle adjustments (diet change, fitness plans, etc.). Clinical trials may also be designed to compare a new therapy with the current standard, or to a dummy pill. The purpose of these studies is to find if new methods of intervention that are helpful and safe.

For example, a new drug for depression may be given to participants who suffer from depression to determine whether or not it works, it’s safe, and how effective it is when compared with an older anti-depressant. Clinical trials designed for drug development run over several years, and are described in phases (i.e. Phases I, II, III trials). It takes roughly seven years for a potentially beneficial drug to undergo clinical testing. Many drugs don’t complete all three phases of the trails, and even if they do FDA does not approve them because they fail to meet certain standards. A Phase IV is sometimes conducted for drugs that had already been approved and is available on the market, to better understand how that drug works, or to be compared with other meds.


In case you are not eligible to participate in a clinical trial, you still may have access to new, experimental drugs outside of a clinical trial through the ‘Expanded Access Program’.

Observational Studies

As the name implies, an observational study will evaluate the outcomes in a group of subjects according to a protocol or research plan. If it is designed for individuals with depression, participants may receive interventions as part of the medical care, but they will not receive interventions as part of the study (as it happens in clinical trials).

For example, the participants will continue to follow treatment for depression as usual, but the researchers will observe and monitor your symptoms to learn how diet, fitness routine or other lifestyle factors influence your symptoms of depression.

Many people who consider participating first time in a study will chose an observational study, because they can learn about lifestyle changes that prove to be beneficial, while not having to risk taking a new drug that has not been approved by the FDA.
