Using Structural Equation Modelling to Explore the Relationship Between Patient-Centered Communication, Human Papilloma (HPV)-related Knowledge, and Perceived Effectiveness of the HPV Vaccine.

BACKGROUND

Patient-centered communication has emerged as a potent strategy for increasing vaccine uptake. Drawing on evidence-based paths established from previous studies, our study examines the relationship between patient-centered communication, HPV knowledge and perceived HPV vaccine effectiveness. We also explored the sociodemographic factors impacting patient-centered communication, HPV knowledge and perceived HPV vaccine effectiveness.

METHODS

We analyzed data from the Health Information National Trends Survey (HINTS) 5, Cycle 1, ran Structural equation modeling (SEM) to test the pathways in our conceptual framework.

RESULTS

Our sample comprised 2522 adults aged 18-79 (mean age 47.98 years) who were predominantly Non-Hispanic White (67.65%), female (53.31%), and heterosexual (95.12%). The model fit statistics for the final structural model indicated a good fit [RMSEA= 0.039, CFI=0.99 TLI= 0.99, and SRMR =0.070]. The path linking patient-centered communication to HPV knowledge (β=0.011, p<0.05), and the knowledge-mediated path linking patient-centered communication to HPV vaccine effectiveness (β=0.007, p<0.05) were found to be statistically significant.

CONCLUSION

HPV researchers must delve deeper into patient-centered communication practices to improve vaccine uptake. Tailoring conversations to individual needs and preferences is key to enhancing HPV knowledge, and ultimately improve perceptions of HPV vaccine effectiveness and increase its acceptability.
