Implementing Johnson’s Behavioral System Model in a Patient With Myocardial Infarction: A Case Study

Background and Aim: Patients with myocardial infarction require a comprehensive nursing care plan due to the chronic and complex nature of the condition. Nursing models can provide a framework and establish goals for the nursing process, enabling more effective and holistic clinical care. Therefore, this study aimed to evaluate the impact of implementing the nursing process based on Johnson’s behavioral system model in patients with myocardial infarction. Materials and Methods: In this case report, we present the nursing process for a patient with a myocardial infarction who was referred to Hajar Hospital in Shahrekord, Iran, in ۲۰۲۵. Data were collected during the assessment phase using the “Johnson behavioral system model survey form,” which involved observation, interviews, and physical examinations. Nursing diagnoses were established, categorizing behaviors as stable or unstable. Care goals were developed to promote and maintain stable behaviors while aiming to reduce or eliminate unstable behaviors. These goals were shared with patients. Nursing interventions were implemented and evaluated to achieve the established goals. Data analysis was presented in tabular format. Results: The results indicated that the client exhibited unstable behaviors in four behavioral subsystems, specifically dysfunction in the aggression and protection, avoidance, reserve, and sexual subsystems. Following the implementation of the designed nursing interventions, these unstable behaviors decreased. Conclusion: Johnson’s behavioral model can effectively modify and address clients’ unstable behaviors. Therefore, this model should be adopted as a nursing care framework.
