Comprehensive Model of Information Seeking
The Comprehensive Model of Information Seeking, or CMIS, is a theoretical construct designed to predict how people will seek information. It was first developed by J. David Johnson and has been utilized by a variety of disciplines including Library and Information Science and Health Communication.
The CMIS has been empirically tested in health and organizational contexts〔Johnson, J. D., & Meischke, H. (1993). Cancer-related channel selection: An extensionfor a sample of women who have had a mammogram. Women & Health, 20, 31-44.; Johnson, J. D., Donohue, W. A., Atkin, C. K., & Johnson, S. H. (1995). A comprehensive model of information seeking: Tests focusing on a technical organization.
Science Communication, 16, 274-303.〕 The CMIS has inherent strengths for studying how people react to health problems such as cancer.〔Johnson, J. D., Andrews, J. E. & Allard, S. (2001). A Model for Understanding and Affecting Genetics Information Seeking. Library and Information Science Research 23(4): 335-349.〕 The CMIS specifies ''antecedents'' that explain why people become information seekers, ''information carrier characteristics'' that shape how people go about looking for information, and ''information seeking actions'' that reflect the nature of the search itself.

The CMIS has been quantitatively tested and performs well when it comes to health information seeking behaviors (HISB).〔 There are three main schemas in the CMIS. These are: Antecedents, information field, and information seeking actions. The antecedents are those factors that determine how an information consumer will receive the information. Those factors are: Demographics, personal experience, salience, and beliefs. These factors are fluid and can change during the health information seeking process. The second schema is the information fields that consist of characteristics and utilities. This schema is concerned with the channels and carriers of information. A person’s understanding is developed through the information field. The third schema involves the transformational processes and measured by the consumer’s understanding of the messages received through the information field. The final schema involves information seeking actions. This is what the consumer does as a result of the first two schemas through information seeking. There are three major dimensions: the scope, depth, and method of information seeking.〔
