Objectives:
to evaluate the effect of persuasive communication in the modulation of the behavioral intention of reducing the consumption of salt in heart failure patients.
Methods:
pilot quasi-experimental study with one group, before and after the application of audiovisual persuasive communication, as guided by the Theory of Planned Behavior. This study used a form built and validated to measure behavioral variables (Beliefs, Attitude, Subjective Norm, and Perceived Behavioral Control). Wilcoxon's test and Spearman's correlation were applied.
Results:
82 heart failure patients who were being monitored in outpatient clinics participated. The medians of the behavioral variables increased significantly after the exposition to persuasive communication, showing a high level of intention to execute the behavior.
Conclusions:
persuasive communication positively contributed to influence the behavioral intention of reducing the consumption of salt in people with cardiac insufficiency.
