This study investigated how self-rated health and socioeconomic status are associated with behaviour ofcancer survivors regarding desire for information. For this association, we compared survivors who did notseek information about cancer with those who did. We examined how sociodemographic, socioeconomic, cancerrelated,and health information factors are associated with self-rated health (SRH) by health information seeking/avoiding behavior in a survey of 502 post-treatment cancer patients. In the information seeking group, all fourfactors exhibited significant relationships with SRH. SRH values were significantly high for women (p<0.05),non-Hispanic White (p<0.05), and educated (p<0.01) participants, and for those who had high self-efficacy to usehealth information by themselves (p<0.01). Furthermore, in the information avoiding group, not only were thereno significant relationships between socioeconomic status (SES) and SRH, but there were negative associationsbetween their attitude/capacity and the SRH. In terms of communication equity, the promotion of informationseeking behavior can be an effective way to reduce health disparities that are caused by social inequalities.Information avoiding behavior, however, does not exhibit a negative contribution toward the relationship betweenSRH and SES. Information seeking behavior was positively associated with SRH, but avoiding behavior wasnot negatively associated. We thus need to eliminate communication inequalities using health intervention tosupport information seeking behavior, while simultaneously providing support for avoiders.
