Using SMART Experimental Design to Personalize Treatment for Child Depression

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is: To conduct a pilot SMART (Sequential, Multiple Assignment, Randomized) study with the long-term goal of developing a personalized treatment for child depression. To collect pilot data on ways to personalize treatment for child depression using cognitive behavioral therapy (CBT), caregiver-child treatment, or both.

Detailed Description
-----------------
Child depression is among the most prevalent and impairing pediatric conditions and constitutes a major public health concern. Unfortunately, treatment benefits are relatively modest and short-lived with sizeable percentages of children who maintain depressive symptoms following treatment. This problem may be addressed in part by personalizing treatment, including determining which children will benefit from CBT, which children will benefit from caregiver-child treatment, and which children will benefit from both. The goal of the current study is to pilot test an innovative experimental design called Sequential, Multiple Assignment, Randomized Trial (SMART), which is used for development of personalized treatments, collect pilot data, and assess the acceptability and feasibility of using this design, in preparation for a full-scale SMART in a larger clinical trial and for the development of personalized treatment.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cognitive Behavioral Therapy (CBT)<br>Type of talk therapy that focuses on individual behavioral and cognitive skills. | Behavioral: Cognitive Behavioral Therapy (CBT)<br>* Children will first be randomized into Stage 1 of CBT or Caregiver-Child Treatment. Stage 1 will include six sessions. After Stage 1, child's response to treatment will be evaluated. Responders will be re-randomized into Stage 2 of no treatment or continuation of CBT. If randomized to no treatment, termination session will be completed. If randomized to continuation of CBT, the treatment will include six sessions and a termination session. Insufficient responders will be re-randomized into Stage 2 of continuation of CBT or Caregiver-Child Treatment. Stage 2 will include six sessions and a termination session.<br>|
| Experimental: Caregiver-Child Treatment<br>Type of talk therapy that involves the child and the caregiver and focuses on behavioral and cognitive skills. | Behavioral: Caregiver-Child Treatment<br>* Children will first be randomized into Stage 1 of CBT or Caregiver-Child Treatment. Stage 1 will include six sessions. After Stage 1, child's response to treatment will be evaluated. Responders will be re-randomized into Stage 2 of no treatment or continuation of Caregiver-Child Treatment. If randomized to no treatment, termination session will be completed. If randomized to continuation of Caregiver-Child Treatment, the treatment will include six sessions and a termination session. Insufficient responders will be re-randomized into Stage 2 of continuation of Caregiver-Child Treatment or CBT. Stage 2 will include six sessions and a termination session.<br>|
