Short-term Intervention and Health Trajectories After Mass Trauma

Study Overview
=================
Brief Summary
-----------------
This study has two aims. The first is to understand more of what may be typical health trajectories after mass trauma for children and adults and what predicts these trajectories. The second is to understand what may be effective early interventions to prevent long-term health and psychosocial problems for youth (6-19). Participants are recruited from an outreach program implemented after a landslide killed 11 persons and destroyed 33 houses in Gjerdrum in Norway. One third of the inhabitants were evacuated. All evacuated are contacted and screened for trauma related difficulties. Those who have significant post-trauma reactions are offered trauma focused interventions.

Detailed Description
-----------------
Two short step-wise interventions are developed for this study as an early intervention after mass trauma based on components from TF-CBT to test the relative importance of dosage and the sequencing of components.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: TF-CBT-Skills<br>Step 1: 4-5 sessions with stabilization/skill building Step 2: 4-5 sessions with narrative and cognitive processing | Behavioral: TF-CBT-Short<br>* Participants receive either 4-5 sessions of TF-CBT-Skills or TF-CBT-Narr. If the participant still has significant PTSS they are provided with step two which is the components provided in the arm they did not receive.<br>|
| Active Comparator: TF-CBT-Narr<br>Step 1: 4-5 sessions with narrative and cognitive processing Step 2: 4-5 sessions with stabilization/skill building | Behavioral: TF-CBT-Short<br>* Participants receive either 4-5 sessions of TF-CBT-Skills or TF-CBT-Narr.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| PTSD | Measured with the Child and adolescent trauma screen (CATS). Range 0-60. Higher score means worse outcome. | Pre-treatment | 
| PTSD | Measured with the CATS (after 4-5 sessions) | After 5 weeks | 
| PTSD | Measured with the CATS (for those who continue to Step two) | After 9 weeks | 
| PTSD | Measured with the CATS | After 21 weeks | 
| PTSD | Measured with the CATS | After 33 weeks | 
| PTSD | Measured with the CATS | After 45 weeks | 
| PTSD | Measured with the CATS | After 57 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Depression | Measured with Moods and feelings questionaire (MFQ-short). Range 0-13. Higher scores means worse outcome. | Pre-treatment | 
| Depression | Measured with MFQ-short | After 5 weeks | 
| Depression | Measured with MFQ-short | After 9 weeks | 
| Depression | Measured with MFQ-short | After 21 weeks | 
| Depression | Measured with MFQ-short | After 33 weeks | 
| Depression | Measured with MFQ-short | After 45 weeks |
