Laboratory-based Hypnosis Intervention on Pain Responsivity in Adolescents With Sickle Cell Disease

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to test the effects of a laboratory-based hypnosis session compared to an attention control condition on peripheral blood flow, autonomic stress responses, and acute pain responses in adolescents (ages 12-21) with sickle cell disease, and examine how perceived disease-related stigma may affect these responses.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in peripheral blood flow before and during the intervention | Peripheral blood flow will be measured using continuous readings of oxygen saturation, pulse rate, and pulse waveform from the thumb and change in blood flow will be assessed by comparing levels of blood flow during the pre-intervention period (15 minutes prior to intervention to a minute before the start of intervention) from blood flow during the intervention period (from the start of the intervention until 30 minutes after the start of the intervention). | Beginning 15 minutes prior to the intervention (hypnosis or attention control) and continuing during 30 minutes of the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in pain threshold temperature | Pain threshold temperature will be determined by when participants report they first feel pain and change in pain threshold temperature will be assessed by comparing pain threshold temperature during the pre-intervention period (12 minutes before the start of the intervention) from pain threshold temperature during the intervention period (15 minutes after the start of the intervention). | 12 minutes before the start of the intervention and 15 minutes after the start of the intervention. | 
| Change in pain tolerance temperature | Pain tolerance temperature will be determined by when participants report they can no longer tolerate the pain and change in pain tolerance temperature will be assessed by comparing pain tolerance temperature during the pre-intervention period (9 minutes before the start of the intervention) from pain tolerance temperature during the intervention period (18 minutes after the start of the intervention). | 9 minutes before the start of the intervention and 18 minutes after the start of the intervention. | 
| Change in heat pulse pain intensity ratings | Heat pulse pain intensity ratings will be determined by participants' self-report of heat pulse pain intensity (rated on a 0-10 scale, with 0 being no pain and 10 being worst pain), and change in heat pulse pain intensity will be assessed by comparing pain tolerance temperature during the pre-intervention period (5 minutes before the start of the intervention) from heat pulse pain intensity during the intervention period (21 minutes after the start of the intervention). | 5 minutes before the start of the intervention and 21 minutes after the start of the intervention. | 
| Change in the effect of the intervention on peripheral blood flow at different levels of disease-related stigma | Stigma will be assessed via a questionnaire completed prior to the start of the laboratory session and will be compared to the change in effect, which is assessed by comparing levels of blood flow during the pre-intervention period (15 minutes prior to intervention to a minute before the start of intervention) from blood flow during the intervention period (from the start of the intervention until 30 minutes after the start of the intervention). | 15 minutes prior to the start of the intervention to a minute before the start of the intervention and from the start of the intervention to 30 minutes after the start of the intervention | 
| Change in the effect of the intervention on pain threshold temperature at different levels of disease-related stigma | Stigma will be assessed via a questionnaire completed prior to the start of the laboratory session and will be compared to the change in effect, which is assessed by comparing pain threshold collected 12 minutes before the start of the intervention and 15 minutes after the start of the intervention. | 12 minutes before the start of the intervention and 15 minutes after the start of the intervention | 
| Change in the effect of the intervention on pain tolerance temperature at different levels of disease-related stigma | Stigma will be assessed via a questionnaire completed prior to the start of the laboratory session and will be compared to the change in effect, which is assessed by comparing pain tolerance collected 9 minutes before the start of the intervention and 18 minutes after the start of the intervention. | 9 minutes before the start of the intervention and 18 minutes after the start of the intervention. | 
| Change in the effect of the intervention on heat pulse pain intensity ratings at different levels of disease-related stigma | Stigma will be assessed via a questionnaire completed prior to the start of the laboratory session and will be compared to the change in effect, which is assessed by comparing pain intensity collected 5 minutes before the start of the intervention and 21 minutes after the start of the intervention. | 5 minutes before the start of the intervention and 21 minutes after the start of the intervention. |
