The Development and Validation of the Colonoscopy Joking Scale

Joking is an important communication behavior that helps people cope with colorectal cancer and colonoscopy screening. However, whether joking serves a beneficial or maladaptive function in the context of colorectal cancer screening remains unknown. The lack of a valid scale impedes our understanding of how joking influences colonoscopy uptake. This study aims to develop and validate the Colonoscopy Joking Scale, a scale of joking behaviors in colonoscopy screening. A sample of Mturk participants aged 50-75 (N = 105) who were not compliant with colonoscopy screening recommendations was recruited to rate items for three joking factors and a measure of colonoscopy screening intentions. Two joking factors (i.e., screening-related and sexual connotation) related to colonoscopy screening and one related to general health were identified in the analysis. The psychometric analysis demonstrated strong convergent, predictive, and discriminant validity. The Colonoscopy Joking Scale will be helpful to understand what joking factor is associated with specific barriers to colonoscopy for different patients so that effective educational and interventional programs can be implemented.
