A cross-sectional study based on the Comprehensive Model of Information seeking: which factors influence health information-seeking behavior in patients with periodontitis.

Background: To investigate the current status of health information-seeking behavior (HISB) of periodontitis patients, and to identity its main influencing factors using the Comprehensive Model of Information Seeking (CMIS).

Methods: In total, 274 periodontitis patients were recruited from a specialized dental hospital in Hangzhou by purposive sampling method for a cross-sectional study. Demographics, direct experience, salience, beliefs, characteristics and utility were 6 variables of CMIS. Data were collected from the patients by using the general information questionnaire, the Health Information Seeking Behavior Scale, the Self-Efficacy Scale for Self-care (SESS) for measuring belief, the Short Form of Health Literacy Dental Scale (HeLD⁃14) for measuring direct experience, and the Brief Illness Perception Questionnaire (BIPQ) for measuring salience. Univariate analysis and regression analysis were utilized to determine the factors influencing the HISB.

Results: The HISB score of periodontitis patients in this study was 3.68 ± 0.40. The low level of HISB was negatively associated with multiple factors, including age of 40 ~ 59 (odds ratio [OR] 0.041, 95% confidence interval [CI] 0.006-0.299), age of 18 ~ 39 (OR 0.053, 95%CI 0.008-0.364), low level of understandability of information (characteristic) [OR 0.317, 95%CI 0.119-0.840] and low level of satisfaction of information (utility) [OR 0.027, 95%CI 0.008-0.089]. However, low level of HISB was positively correlated with medium self-efficacy level [OR 3.112, 95% CI 1.463-6.747] and low self-efficacy level [OR 8.061, 95% CI 1.981-32.807].

Conclusions: According to the CMIS model, we identified several factors influencing health-seeking behaviors (HISB). Lower levels of HISB are closely associated with older age and lower level of understandability and satisfaction of information. Conversely, higher self-efficacy may encourage patients to seek health information more actively. Therefore, it is essential to focus on elderly patients and assess their information expectations and needs in a timely manner, while also working to enhance their self-efficacy to promote more effective access to health information.
