title: A Lens Model Approach to the Communication of Pain.
abstract: Two studies examined the expression and detection of suppressed, genuine, and exaggerated pain. In Study 1, videotaped participants underwent an acute laboratory pain stressor and completed pain ratings. In Study 2, the lens model examined the cues encoders displayed while in pain (facial expressions of pain and viewers' global impressions), the cues decoders used to infer pain in the videotaped encoders, and decoders' accuracy in making judgments of pain. Results revealed expression differences between the suppressed, genuine, and exaggerated pain such that exaggerated expressions contained more tightened facial expressions while genuine expressions of pain contained more open facial expressions of pain. Decoders were accurate at detecting pain only in the exaggerated pain expressions. These results highlight the need for improving providers' accuracy in detecting pain intensity for suppressed, genuine, and exaggerated pain displays. Trainings should focus on teaching providers that patients who appear more agitated and less composed may be suppressing pain, while patients who appear more tense and determined may be exaggerating pain. Finally, patients who seem to not be in that much pain because they are not showing tightened facial expressions may actually be experiencing higher intensities of genuine pain.
