The Source and Credibility of Colorectal Cancer Information on Twitter.

Despite the rapid penetration of social media in modern life, there has been limited research conducted on whether social media serves as a credible source of health information. In this study, we propose to identify colorectal cancer information on Twitter and assess its informational credibility. We collected Twitter messages containing colorectal cancer-related keywords, over a 3-month period.

Validation of the Korean Version of Schedule of Fatigue and Anergia: General Physician Questionnaire.

The Schedule of Fatigue and Anergy/General Physician (SOFA/GP) was developed to screen for prolonged fatigue in the primary care setting.
