Treatment of Depression Using a Mobile Application in the Dominican Republic
Depression MildDepression ModerateThe overall objective of this study is to develop a feasible and acceptable mental health app which delivers Cognitive Behavioral Therapy (CBT) for depressed patients in the Dominican Republic. This proposal meets the research objectives of NIMH in delivering mental health care to populations with low literacy, and supporting health care systems in monitoring and improving the quality of mental health. In the proposed study, the investigators will upgrade, implement, and evaluate a depression treatment app and assess trained facilitators' capacity in managing participants' depression symptoms using the app. The investigators will conduct a randomized controlled trial (RCT) among 120 participants who screen positive for mild to moderate depression or anxiety on the Patient Health Questionnaire (PHQ-9) or GAD- 7 via a university-based Covid mental health hotline. The app, El Buen Consejo Móvil (EBCM), will be downloaded to the participants' own Android phone. Participants will be randomized to receive the EBCM app with the functionality to connect individuals to one another via a facilitator-guided chat room (ECBM-G; n= 60) or to receive the same contents as an individualized facilitator-guided CBT program without the group functionality (ECBM-I; n=60). Recruitment and mixed-methods data collection will be conducted by phone, given current circumstances surrounding the Covid-19 pandemic. Process outcomes will be evaluated for the trained facilitators. The primary outcomes for app users will be acceptability of the app and perceptions of social interactivity for those randomized to the group condition. Validated questionnaires will be administered to measure perceived emotional support, loneliness, and interactivity. Level of adherence and effectiveness, the secondary outcomes, will be assessed by frequency of interaction with the app, completion of treatment for either treatment modality, and change in depressive symptoms. The investigators hypothesize that the use of the app for guided self-help can be enhanced through group interaction. EBCM can result in increased access to care in low-income community settings where patients are not currently receiving treatment due to logistical barriers and the stigma of seeking care in a mental health care setting.

Effects of Low Dose Ketamine Given at Induction of Anesthesia on Postoperative Mood in Patients...
DepressionMajor Depressive DisorderKetamine has been shown to have an antidepressant effect when given intravenously in doses of 2mg/kg. Ketamine is used as a standard induction drug during general anesthesia. It is known in this instance to decrease postoperative pain. No one has studied whether or not ketamine when given in doses used during general anesthesia (0.5mg/kg intravenous) has an antidepressant effect on surgical patients who suffer from depression. The study is designed to determine whether or not a small dose of ketamine when given at the induction of anesthesia could have an antidepressant effect on surgical patients with depression.

Adjunctive Use of Celecoxib in the Treatment of Bipolar Postpartum Depression
Bipolar DisorderPostpartum DepressionThe investigators will conduct a 6-week, randomized, double-blind, placebo-controlled trial of celecoxib as an add-on treatment to the mood stabilizer among women with bipolar I or II postpartum depression. Women who are taking a mood stabilizer for treatment of bipolar disorder in the postpartum treatment will receive either a placebo or celecoxib add-on treatment. Patients will be monitored regularly to assess psychiatric symptoms and side effects. The investigators aim to evaluate the potential antidepressant effect of celecoxib in bipolar postpartum depression.

Group Treatment for Adolescents With Depression
DepressionYouth with depressive symptoms are at risk for a range of problems later in life. This includes problematic interpersonal relationships, occupational stress, and the occurrence of adult mental disorders. The main purpose of this study is to test how effective two types of group therapy are at reducing depressive symptoms in youth. A focus on group therapy is important because group therapy allows for many youth to be treated in a short amount of time. Group therapy is also helpful because youth can get social support and feel less alone in their symptoms when they participate in group. This study compares two groups, one that targets skills for managing difficult emotional experiences (dialectical behavior therapy skills group) and another group focuses on psychoeducation and is based on a publicly available treatment manual from the Services for Teens At Risk (STAR) Center at the University of Pittsburgh. The results of this study will provide insights regarding the comparative efficacy of these two treatments, and regarding predictors of treatment response.

Short-term Cognitive Training in Late-life Depression
DepressionThe purpose of this study is to examine the effects of the alternative uses training (AUT) and word association training (WAT) on cognitive functions and mood symptoms in late-life depression (LLD). The hypotheses are: post-training cognitive performance will be superior to pre-training cognitive performance post-training depressive symptomatology will be less severe as compared with pre-training clinical severity and AUT group will show better post-training cognitive performance and improved mood symptoms when compared with the WAT group.
