Brief Summary

Despite carrying the vast majority of the global mental disorder burden, 75% of adults with mental disorders in Low and Middle Income Countries have no access to services. This study will test strategies for integrating first and second line evidence-based depression and trauma-related disorder treatments with primary care services at a large public sector hospital and conduct robust cost and cost-benefit analyses of each treatment to produce a "menu" of cost-benefit options for personalized, integrated mental health care with corresponding effectiveness and implementation values.

Outcome Measures

Primary Outcomes (2)

  • Number of Participants With Major Depression at End of Treatment

    Number of Participants with Major Depression. The Beck Depression Inventory-Second Edition (BDI-II) was used and a score of 19 or greater was defined as positive for major depression. BDI-II score below 19 is defined as negative for major depression. Scores range from 0 to 63 with higher total scores indicating more severe depressive symptoms.

    End of 1st line Treatment (up to month 6) and end of 2nd line Treatment (up to month 12)

  • Number of Participants With PTSD

    Number of Participants with PTSD. The PTSD Checklist for DSM-5 (PCL-5) was used and score of 23 or greater is defined as positive for PTSD. PCL-5 score below 23 is defined as negative for PTSD. Score range from 0 to 80 with higher total scores indicating more severe PTSD symptoms.

    End of 1st line Treatment (up to month 6) and end of 2nd line Treatment (up to month 12)

Study Arms (5)

Interpersonal psychotherapy

ACTIVE COMPARATOR

IPT was developed in the 1980s by Gerald Klerman and Myrna Weissman to address interpersonal issues in depression. IPT is now considered evidence-based, first-line treatment for depression. IPT improves symptoms by addressing problems in social relationships. IPT is traditionally delivered as weekly one-hour sessions over 12 weeks, focused on one interpersonal problem area.

Behavioral: Interpersonal Psychotherapy

fluoxetine

ACTIVE COMPARATOR

Fluoxetine is a selective serotonin reuptake inhibitor that is FDA approved for the treatment of depression. Compared to placebo, fluoxetine is more likely to produce symptom response for MDD. Despite the interim development of many other antidepressants since the development of fluoxetine, it remains a first line treatment for depression.

Drug: Fluoxetine

Fluoxetine after IPT

ACTIVE COMPARATOR

participants who do not remit from MDD and PTSD after treatment with IPT may be randomized to fluoxetine.

Drug: Fluoxetine

IPT after fluoxetine

ACTIVE COMPARATOR

participants who do not remit from MDD and PTSD after treatment with fluoxetine may be randomized to IPT.

Behavioral: Interpersonal Psychotherapy

IPT + fluoxetine

ACTIVE COMPARATOR

participants who do not remit from MDD and PTSD after treatment with fluoxetine may be randomized to IPT + fluoxetine.

Masking Details
participants will be evaluated by an outcomes assessor that is not aware of which treatment the participant is receiving. This will be achieved by keeping the randomization key locked and accessible only to the study coordinator and investigators. Participants who are scheduled for assessments will be reminded not to spontaneously disclose their treatment modality to the outcomes assessor.

NIMH Data Archive The National Institutes of Health (NIH) and NIMH have developed a federation of data repositories called the NIMH Data Archive (NDA) to store the collection of data from participants in research studies related to mental health, regardless of the source of funding. The extensive information collected by these studies, and subsequently stored in the National Database for Autism Research (NDAR), the NIH Pediatric MRI Repository (PedsMRI), the National Database for Clinical Trials Related to Mental Illness (NDCT), and the Research Domain Criteria Database (RDoCdb) provides a rare and valuable scientific resource. The NIH and the NIMH seek to encourage the use of these resources to achieve rapid scientific progress. In order to take full advantage of such resources and maximize their research value, it is important that data be made available, on appropriate terms and conditions, to the largest possible number of qualified investigators in a timely manner.

Shared Documents
STUDY PROTOCOL, CSR
Time Frame
Data will be made available to the NIMH data archive as soon as it is verified as clean and complete, with at least annual updates throughout the duration of the study. Data will be be available indefinitely or for as long as the NIMH repositories supports the electronic data storage.
Access Criteria
The investigative team and our NIMH and GACD partners will review requests for data. Evaluation will include scientific merit of the proposal, overlap versus building upon the study goals.
