Rapid Induction Analgesia: Audio recordings of hypnosis for induced pain in a student sample

INTERVENTION: Rapid Induction Analgesia is a 20‐minute hypnosis procedure with suggestions for relaxation and pain mediation. The intervention will be given as an audio recording that lasts for 20 minutes. There will be two experimental conditions, one where participants listen to the recording two days, then one day before and during a testing session and one where they just listen during the testing session. In the testing session pain will be induced using capsaicin applied to their forearms. Participants will then listen to the recording, or relaxing music, and then rate pain distress and intensity in response to several mechanical stimuli applied to the forearm. Mechanical stimulation will be applied using an algometer which measures pressure, a temperature simulator that will apply heat of approximately 43C and a Neuropen that will produce a sharp pricking sensation. The testing session will take approximately one hour. CONDITION: Acute Pain PRIMARY OUTCOME: Pain intensity associated with physical stimuli on capsaicin application site in experimental group versus control group as assessed on a scale of 1‐10. Psychological distress associated with physical stimuli on capsaicin application site in experimental group versus control group as assessed on a scale of 1‐10. SECONDARY OUTCOME: Heat intensity will be assessed using a thermal simulator applied to the forearm. Participants will rate heat intensity on a scale from 1‐10 Pressure pain threshold will be measured using an algometer Sharpness, using a neuropen applied to the forearm, with participant ratings of sharpness on a 1‐10 scale INCLUSION CRITERIA: Adults 18 and over Generally good physical and mental health
