简要总结
The goal of this study is to investigate the role of physical pain in the link between childhood adversity and later psychopathology. Children who are participating in a larger longitudinal study will be asked to submerge their hand in cold water and hold it in the cold water as long as possible. Participants will do this twice, once alone and once holding the hand of their parent, to examine the role of parental support in pain development. The study will examine self-report of pain and salivary cortisol response to pain. It is hypothesized that children who have been exposed to more adversity will experience increased pain response and increased psychopathology symptoms. It is expected that higher social support in the family will decrease this relationship.
详细描述
This study will initiate a program of prospective research, linking early life adversity to both pain and psychopathology symptoms in the pre-adolescent period. This study will examine these links using an existing longitudinal sample of 6.5-9.5 year-old children experiencing familial stress. The project will examine the relationship between dysregulation and pain sensitivity from the behavioral perspective, but also through HPA axis dysregulation. Finally, the project will probe parental support as a moderator on the relationship between dysregulation and pain and psychopathology symptoms. The project will use a novel adaptation of the cold pressor test to examine experimental pain sensitivity as a function of parental support by including a condition in which the child holds the hand of their parent during the task. The project will also examine the neural basis of social support through parent-child brain synchronization. Support for the proposed model may indicate that interventions that increase parental support might decrease both pain and psychopathology.

研究组 & 干预措施
Pain Assessment
Children will submerge their hand in cold water and be asked to hold it in as long as possible. They will do this both alone and holding the hand of a parent (counterbalanced).
干预措施: Parental Support Cold Pressor Task (Behavioral)
结局指标
主要结局
Pain Tolerance
时间窗: 0-120 seconds
Time hand is held in cold water
Pain Sensitivity
时间窗: 0-60 seconds after experiencing stimulus
Self-reported score on the Visual Analogue Scale for Pain. Participants use a physical sliding scale to indicate how much pain they experienced \[ higher numbers are equal to more pain; (no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm)\]
