The Behavioral System Model proposed by Dorothy E. Johnson represents an essential facet of modern nursing theory, focusing on the interplay between various behavioral systems and their impact on patient health. This model places a premium on understanding the organized and dynamic nature of behaviors that each individual exhibits. The following sections will elucidate the concept definition of behavioral systems and outline the critical behavioral system model components essential for nursing practice.
Definition of Behavioral Systems
Behavioral systems refer to structured patterns of behavior that coexist within individuals, influenced by biological, psychological, and social factors. Through the lens of nursing theory, these systems emphasize the interaction and interdependence of behaviors, asserting that health outcomes are significantly influenced by how these behaviors are organized. Johnson’s model articulates that understanding these systems is critical for effective nursing care, as they help healthcare professionals identify areas where patients may be experiencing imbalance and require support.
Components of the Johnson Behavioral System Model

Within the Johnson Behavioral System Model, several components emerge that serve to categorize human behavior into distinct subsystems. Johnson identified seven behavioral system model components:
- Attachment
- Achievement
- Aggressive
- Dependence
- Sexual
- Ingestive
- Eliminative
Each of these subsystems possesses three functional requirements necessary for maintaining balance: protection from harmful influences, nurturing through appropriate environmental input, and stimulation for growth. Johnson’s insights into the behavioral system model components illuminate how these subsystems can interact and influence each other, essential for restoring equilibrium when disruptions occur. This holistic understanding is pivotal in nursing practices, where diverse factors converge to shape patient h

This holistic understanding is pivotal in nursing practices, where diverse factors converge to shape patient health and wellbeing.
The Role of the Nurse in the Model
Johnson’s Behavioral System Model positions nursing as a fundamental component of behavioral science, highlighting its critical role in understanding patient behavior and influencing health outcomes. The model suggests that to fulfill their nursing responsibilities effectively, nurses must engage with the various behavioral subsystems that govern patients’ actions. This requires a nuanced approach that balances scientific knowledge with compassionate care, enabling nurses to address both physical and emotional dimensions of health.
Nursing as a Behavioral Science
The integration of nursing with behavioral science enables practitioners to observe and respond to patient needs more effectively. Nurses analyze behaviors that may indicate underlying health issues, applying research-based knowledge to foster a supportive environment conducive to healing. In this context, the nursing role encompasses not only the assessment of patients but also the creation of individualized care plans that promote optimal functioning across the identified subsystems. By focusing on holistic assessments, nurses can pinpoint interconnected problems and facilitate improved health outcomes for their patients.
Responsibilities of the Nurse Practitioner
Nurse practitioners carry substantial responsibilities in executing the principles outlined in Johnson’s model. Primarily, they evaluate the balance within a patient’s behavioral system, identifying any disruptions that could stem from internal stressors such as anxiety or external factors like environmental influences. Continuous assessment is vital as it allows for flexibility in care plans, ensuring they evolve alongside the patient’s needs. Additionally, nurse practitioner roles include the collaboration with interdisciplinary teams, which enhances the effectiveness of interventions aimed at restoring stability and promoting holistic well-being. This commitment to addressing both medical and behavioral challenges underscores the critical nature of nursing practice in achieving healthy patient outcomes.
Johnson Behavioral System Model: Seven Subsystems Explained
Dorothy Johnson viewed each person as a behavioral system made up of seven interconnected subsystems. Think of these subsystems as seven essential parts of a person that work together to maintain balance and health. When one subsystem is affected, it impacts the others—much like how a mobile hanging above a baby’s crib will tilt completely if just one piece is moved.
Before we dive into each subsystem, remember that:
- Each subsystem has a purpose (what it aims to accomplish)
- Each has functional requirements (what it needs to work properly)
- Each displays behaviors (observable actions)
- Each requires nursing care when imbalanced
1. Attachment and Affiliative Subsystem: Building Meaningful Connections
What It Is
This subsystem governs how we form social bonds and maintain relationships with others. It’s about our need to belong and connect.
Real-World Example
Meet Mrs. Chen: An 82-year-old widow hospitalized for pneumonia. She rarely has visitors and appears withdrawn. Nurses notice she brightens significantly when they spend extra time talking with her during medication administration.
Functional Assessment
- Healthy Function: Mrs. Chen maintained close relationships with her church group before hospitalization
- Dysfunction: Isolation in hospital has disrupted her attachment patterns
Nursing Application
- Personalized Care: The nurse assigns the same staff to Mrs. Chen when possible
- Environmental Adjustment: Places Mrs. Chen in a semi-private room with a compatible roommate
- Family Involvement: Coordinates video calls with her church friends
- Therapeutic Communication: Schedules brief but meaningful daily conversations
Result
Mrs. Chen develops a trusting relationship with her care team, participates more actively in recovery, and experiences reduced anxiety—demonstrating how supporting the attachment subsystem promotes healing.
2. Dependency Subsystem: Balancing Help and Self-Reliance
What It Is
This subsystem controls behaviors related to caretaking, assistance, and the balance between dependence and independence.
Real-World Example
Meet James: A 45-year-old man recovering from a stroke who is frustrated by his new limitations. He refuses help with activities he cannot safely perform alone, saying “I don’t need anyone’s help!”
Functional Assessment
- Healthy Function: Before his stroke, James appropriately sought help for complex tasks while maintaining independence
- Dysfunction: Now alternates between refusing necessary assistance and becoming frustrated when tasks are difficult
Nursing Application
- Gradual Independence: The nurse creates a schedule where James does more for himself each day
- Reframing Assistance: Explains how accepting help now leads to greater independence later
- Partnership Approach: “Let’s work on this together” instead of “Let me do this for you”
- Celebrating Milestones: Acknowledges each new skill James masters
Result
James begins to accept necessary help while working toward independence, showing how properly supporting the dependency subsystem creates a healthy balance between assistance and autonomy.
3. Ingestive Subsystem: Nourishing the Body and Mind
What It Is
This subsystem manages behaviors related to eating, drinking, and taking in nourishment—both what and how we consume.
Real-World Example
Meet Sophia: A 16-year-old with newly diagnosed diabetes who is struggling with dietary restrictions. She secretly eats forbidden foods and then lies about her blood sugar readings.

This subsystem regulates behaviors related to bodily excretion—how we eliminate waste biologically, socially, and psychologically.
Real-World Example
Meet Mr. Rodriguez: A 70-year-old man hospitalized after prostate surgery who is now incontinent. He refuses to leave his room or see visitors due to embarrassment.
Functional Assessment
- Healthy Function: Previously had normal elimination patterns and no social limitations
- Dysfunction: Now experiencing incontinence and social withdrawal due to shame
Nursing Application
- Preserving Dignity: The nurse ensures privacy during care and uses discreet incontinence products
- Scheduled Voiding: Implements a timed toileting program
- Environmental Control: Places his room near the bathroom and creates clear access
- Normalization: Explains that temporary incontinence is common after his procedure
Result
Mr. Rodriguez regains confidence to participate in physical therapy and accept visitors, showing how addressing both physical and psychological aspects of the eliminative subsystem preserves dignity and promotes recovery.
5. Sexual Subsystem: Acknowledging Identity and Intimacy Needs
What It Is
This subsystem encompasses behaviors related to gender identity, sexual expression, and reproduction.
Real-World Example
Meet Maria: A 35-year-old woman recovering from a mastectomy who expresses concerns about her relationship with her husband and her self-image.
Functional Assessment
- Healthy Function: Previously had positive body image and satisfying intimate relationship
- Dysfunction: Now experiencing altered body image and anxiety about intimacy
Nursing Application
- Open Communication: The nurse creates opportunities to discuss concerns about intimacy and relationship changes
- Body Image Support: Teaches Maria how to care for her surgical site while acknowledging emotional responses

- Partner Inclusion: With Maria’s permission, includes her husband in discussions about adjustment
Result
Maria begins to adapt to body changes and communicates more openly with her husband, demonstrating how supporting the sexual subsystem addresses both physical adjustments and relational aspects of health.
6. Aggressive/Protective Subsystem: Safeguarding Self and Values
What It Is
This subsystem manages behaviors related to self-protection, setting boundaries, and responding to threats—both real and perceived.
Real-World Example
Meet Devon: A 19-year-old admitted after a car accident who becomes verbally aggressive when healthcare decisions are made without his input.
Functional Assessment
- Healthy Function: Previously used appropriate assertiveness to protect his interests
- Dysfunction: Now displaying excessive aggression due to feeling threatened and powerless
Nursing Application
- Control Restoration: The nurse involves Devon in care planning: “What time would you prefer to take your medication?”
- Boundary Education: Teaches the difference between assertiveness and aggression
- Predictability: Explains procedures before they happen to reduce threat perception
- Validation: Acknowledges his right to have opinions about his care
Result
Devon’s aggressive outbursts decrease as he gains appropriate control over his care, showing how supporting healthy protective behaviors while redirecting unhelpful aggression balances this subsystem.
7. Achievement Subsystem: Mastering Skills and Environment
What It Is
This subsystem directs behaviors related to accomplishment, intellectual mastery, and skill development.
Real-World Example
Meet Aisha: A 50-year-old teacher who has had a stroke affecting her language abilities. She becomes depressed when unable to read or communicate effectively.
Functional Assessment

How These Subsystems Work Together: A Holistic View
Interconnected Nature
Consider how these subsystems overlap and influence each other:
Case Study: Mr. Jackson Mr. Jackson, a 60-year-old with newly diagnosed heart failure, shows how disturbance in one subsystem affects others:
- Ingestive subsystem is affected by sodium restrictions
- This impacts his achievement subsystem as he can no longer cook favorite family recipes
- His attachment subsystem is strained as social gatherings revolved around these meals
- His aggressive/protective subsystem activates as he feels his identity threatened
- His dependency subsystem struggles with new reliance on medications
- His eliminative subsystem is affected by diuretics
- His sexual subsystem faces challenges due to medication side effects and fatigue
Nursing Application to Multiple Subsystems
Effective nursing care addresses these connections:
- Holistic Assessment: Evaluate all subsystems, not just the most obvious one
- Prioritization: Address the most critical subsystem first while planning for others
- Ripple Effect Planning: Anticipate how interventions in one area will affect others
- Patient Perspective: Ask which subsystem disruption matters most to the patient
Practical Application for Nursing Students
Assessment Questions for Each Subsystem
Attachment:
- “Who are the important people in your life?”
- “How has your illness affected your relationships?”
Dependency:
- “What activities do you need help with now?”
- “How do you feel about asking for assistance?”
Ingestive:
- “Describe your typical eating patterns.”
- “Have you noticed any changes in appetite or enjoyment of food?”
Eliminative:
- “Have you experienced any changes in your bowel or bladder habits?”
- “Are you comfortable using the bathroom facilities here?”
Sexual:
- “Has your condition affected how you see yourself?”
- “Do you have concerns about how this condition might affect intimate relationships?”
Aggressive/Protective:
- “What helps you feel safe and in control?”
- “How do you typically respond when you feel threatened?”
Achievement:
- “What activities give you a sense of accomplishment?”
- “How has your condition affected your ability to do things that matter to you?”
Creating Nursing Care Plans Using Johnson’s Model
- Step 1: Identify which subsystems are imbalanced
- Step 2: Determine what each subsystem needs (protection, nurturance, stimulation)
- Step 3: Plan interventions that specifically address those needs
- Step 4: Evaluate effectiveness by observing behavioral changes
Example: For Mr. Jackson (heart failure patient mentioned earlier):
- Priority Subsystem: Ingestive
- Need: Knowledge about heart-healthy eating while preserving enjoyment
- Intervention: Work with dietitian to modify favorite recipes to be heart-healthy
- Evaluation: Mr. Jackson demonstrates understanding by creating a meal plan that follows restrictions while maintaining satisfaction
Dorothy Johnson’s Behavioral System Model offers a structured way to understand the whole person—not just their medical diagnosis. By recognizing how these seven subsystems interact, nurses can:
- Provide truly holistic care that addresses all aspects of human functioning
- Anticipate problems before they develop by noticing early subsystem imbalances
- Create interventions that promote balance rather than just treating symptoms
- Recognize that behavior has meaning and serves a purpose in maintaining balance
Remember that each patient’s behavioral system is unique, shaped by their culture, experiences, and values. The art of nursing using Johnson’s model lies in understanding each patient’s individual patterns and supporting their return to their optimal balance.
Furthermore, Johnson Behavioral System Model can be effectively juxtaposed against other nursing theories, including Orem’s Self-Care Deficit Theory. While Orem emphasizes the importance of individual self-care abilities, Johnson’s framework places a greater emphasis on the nurse’s role in achieving behavioral equilibrium for their patients. This Johnson model comparison allows for deeper insights into varying approaches to nursing care, reinforcing the necessity for adaptable strategies that meet diverse patient needs. The exploration of these nursing theories further solidifies the importance of acknowledging both self-care capabilities and the facilitative role of nursing in managing patient behaviors and health outcomes.
