Description
At baseline, participants will complete a 2.5-hours study session. In the study session, psychophysical assessments of thermal and pressure stimuli will be performed and sex hormone levels will be analyzed. In addition, demographic, social, pubertal maturation, behavioral and psychological factors will be collected via questionnaires.
In the optional follow-up portion, participants can complete short surveys every 3 months and/or return for study visits after 6 months and/or after every year depending on the participant’s availability. The study visits will include the same procedures as the baseline study visit. Additional surveys regarding new symptoms of pain will be completed. In some cases, participants will meet a pediatric physician who will determine if they meet the criteria for any pain syndrome (for research purposes only).
