Neural Changes Associated With a Mindfulness-based Intervention for Young Adults With Childhood Maltreatment

Study Overview
=================
Brief Summary
-----------------
Childhood trauma is remarkably prevalent, and it has long lasting impact on mental health and neural development. This trial aims to see whether the 8-week mindfulness based intervention can reduce stress related psychological symptoms for young adults with childhood maltreatment, and whether it can promote neural plasticity.

Detailed Description
-----------------
This study recruits young adults with childhood adversity; enrolled subjects either receive an 8-week mindfulness based intervention, or wait for 8 weeks before receiving the intervention. MRI and a battery of self report questionnaires will be administered before and after the intervention; subjects on the waiting list will undergo the same research procedures at the same time as subjects in the intervention group. Primary hypotheses include improved hippocampal plasticity, increased mindfulness and reduced stress and related psychological symptoms.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Mindfulness group<br>This arm receives an 8-week mindfulness based behavioral intervention program. | Behavioral: Mindfulness based intervention<br>* The intervention is an 8-week structured mindfulness based behavioral intervention program that teaches mindfulness meditation, mindful yoga and psychological knowledge about stress.<br>|
| Other: Waitlist control group<br>This arm waits while the mindfulness group receives their intervention, and then receives the mindfulness based intervention after their waiting period. | Behavioral: Mindfulness based intervention<br>* The intervention is an 8-week structured mindfulness based behavioral intervention program that teaches mindfulness meditation, mindful yoga and psychological knowledge about stress.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in Subjects' Perceived Stress Level | Changes in the Perceived Stress Scale scores (post- intervention scores minus pre- intervention scores). Relevant time points used in the calculation include baseline scores at enrollment, and post-intervention/waiting period scores after 2 months of intervention or waiting period. Calculations of the change entail post-intervention/waiting period scores minus baseline scores for each individual subject. The Perceived Stress Scale is a 10 item scale (each responded with Likert scale 0-4), the scale score is the sum of all items, thus the full range of PSS scores is 0-40, with higher scores means worse stress. A reduction in PSS scores (i.e., the change scores being negative) indicates subjects have improved after the intervention by becoming less stressed. | After the 8-week intervention program compared to baseline measurement, or the same time as the intervention group for subjects on the waiting list. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes of Mindfulness | Changes in the mindfulness level as measured by the Mindful Attention Awareness Scale (post-intervention scores minus pre-intervention scores). Relevant time points used in the calculation include baseline scores at enrollment, and post-intervention/waiting period scores after 2 months of intervention or waiting period. Calculations of the change entail post-intervention/waiting period scores minus baseline scores for each individual subject. The MAAS is a 15-item scale each responded with Likert scale 1-6; the MAAS score calculated as the mean of all items, thus the full range of the score is 1-6, with higher scores meaning more mindful. An increase in MAAS score (i.e., a positive score change )means the subject has improved after the intervention by becoming more mindful. | After the 8-week intervention program compared to baseline measurement, or the same time as the intervention group for subjects on the waiting list. |
