Meet our team

DEPRESSD is an international collaborative project involving experts in health policy, psychiatry and statistics as well as investigators who have collected depression screening data. Our mission is to synthesize the global depression screening data in order to develop and apply rigourous methods on assessing depression screening tool accuracy that minimize bias and provide evidence to inform research and policy to improve mental health care. The project builds a database for shared usage and also provides a unique platform for trainee development, including skills in evidence synthesis and statistical modelling. 

 
 

Congratulations to Dr. Zelalem Negeri and the DEPRESSD Team on their publication in The BMJ!

We are happy to share that the DEPRESSD Team's updated IPDMA on the accuracy of the PHQ-9 screening tool has been published in the BMJ. The project, led by Dr. Zelalem Negeri, combined individual participant data from 100 studies (>44,000 participants) to evaluate the screening accuracy of the PHQ-9. The combined sensitivity and specificity of the PHQ-9 were maximized at a cut-off of >=10. Specificity was similar across reference standards, but sensitivity in studies with semi-structured interviews was higher than with fully structured reference standards and with the MINI. Moreover, specificity was higher for men and older participants. The full article can be accessed here. Researchers and clinicians can use our results to determine outcomes, such as the total number of positive screens and false-positive screens, at different PHQ-9 cut-offs for different clinical settings as described in our knowledge translation tool here.

Yesterday, 35 collaborators attended the first DEPRESSD webinar - Addressing overestimation of prevalence based on self-report questionnaires: Are there cost-effective alternatives. For those of you who couldn’t make it to the meeting, you can watch the recording here [LINK]. The DEPREESSD team is planning to have more webinars later in the fall. We will keep you all posted. Thanks to all of you for your collaboration!

DEPRESSD Team published a new IPDMA protocol - Equivalence of the Accuracy of 9 and 10 item Versions of the Edinburgh Postnatal Depression Scale for Screening to Detect Major Depression among Pregnant and Postpartum Women on OSF

2021/06/16

Dr. Xia Qiu, a visiting PhD Student, and the DEPRESSD team published their protocol on OSF. The objectives of the study are (1) to evaluate the equivalence of continuous EPDS-9 and full EPDS scores for assessing depressive symptom severity; and (2) to assess the equivalence of the accuracy of the EPDS-9 and full EPDS across relevant cut-offs for screening to detect major depression.
