Adherence to systemic hypertension drug treatment involves oral 'taking antihypertensive' behavior. This action favors adherence, which is considered a challenge for health teams, because it involves psychosocial factors that are not always under the volitional control of individuals, which results in low adherence with consequent cardiovascular complications. Objective: To develop motivational technologies from the identification of psychosocial determinants of behavior to take oral antihypertensives, with methodological theoretical support of the Theory of Planned Behavior. Method: Methodological study. A total of 278 individuals with systemic arterial hypertension participated. Interviews, questionnaires and evaluation scripts were used. Data analysis was performed by content analysis, Content Validity Index (CVI), Cronbach's Alpha, Chi-square, Fisher's Exact Test, Spearman Correlation, and Wald and R2 Nagelkerke logistic regression. The project was approved by the Research Ethics Committee (CAAE: 79671317.3.0000.5182), and the research took place from December 2017 to October 2019. Results: in phase I- a questionnaire with 40 items was prepared. After some experts‟ analysis a version 2 with 36 items was obtained. The instrument obtained CVI = 0.93 for clarity, CVI = 0.90 for pertinence of the items and CVI = 1.00 for coverage of the constructs. The overall Cronbach's alpha of the instrument was 0.82. In phase II: All theory constructs, plus past behavior, were positively associated (p <0.01) in predicting behavioral intention, with correlation strength ranging from weak, moderate to strong. Behavioral beliefs, subjective norm and perceived behavioral control behaved as significant predictors of behavioral intention, with multiple logistic regression model presenting R2 = 33%. In phase III: A video and 29 messages (15 positive and 14 negative) were prepared and validated. The video showed CVI = 0.93 for clarity and CVI = 1.00 for relevance. All messages had CVI ≥0.80 regarding content and illustrations and were 100% comprehensive. In phase IV: The developed prototype has the following items: contacts; medications in use and controls; home screen with persuasive video; positive and negative persuasive messages, addressing arguments related to beliefs about antihypertensive taking. Conclusion: The identification of psychosocial determinants of “taking the prescribed pills to control hypertension” allowed the development of different types of technologies: behavioral intention measuring instrument, persuasive communications and persuasive messages, to be inserted into a smartphone application. . Technological innovations can and should be applied in the context of health, incorporated into educational actions, especially developed by nursing professionals, considering the potential contributions of these resources in motivating self-care and self-management of the health of individuals with chronic diseases and, particularly, hypertension. systemic.
