Background
Few experimental studies have been conducted on social determinants of pain tolerance.
Purpose
This study tests a brief, computer-delivered social norm message for increasing pain tolerance.
Methods
Healthy young adults (N = 260; 44 % Caucasian; 27 % Hispanic) were randomly assigned into a 2 (social norm) × 2 (challenge) cold pressor study, stratified by gender. They received standard instructions or standard instructions plus a message that contained artifically elevated information about typical performance of others.
Results
Those receiving a social norm message displayed significantly higher pain tolerance, F(1, 255) = 26.95, p < .001, η
p

= .10 and pain threshold F(1, 244) = 9.81, p = .002, η
p

= .04, but comparable pain intensity, p > .05. There were no interactions between condition and gender on any outcome variables, p > .05.
Conclusions
Social norms can significantly increase pain tolerance, even with a brief verbal message delivered by a video.
