Are Rates of Depression Overestimated?

An analysis recently published in the Canadian Medical Association Journal suggests using self-report screening questionnaires rather than diagnostic interviews to diagnose depression – a common practice – results in an overestimation of depression prevalence.

According to researchers from the Lady Davis Institute of the Jewish General Hospital and McGill University, both in Montreal, self-report questionnaires can be used as an initial assessment tool, but additional evaluations are necessary for a definitive diagnosis. While the questionnaires can help identify people who are struggling with mental health issues, a depression diagnosis requires a more thorough evaluation, which is time-consuming and can be expensive to administer.
