Theories and conceptual frameworks in nursing
A working guide to Orem, Roy, Pender, Watson and other widely used frameworks: what each one says, what it can guide in a study, and an example study design for each.
Theory, model, framework: what is the difference?
The terms overlap in practice, so state clearly what you mean in your paper. A concept is a labelled idea, a theory proposes relationships between concepts, a model shows those relationships in a diagram, and a conceptual framework is the structure you build for your study from one or more theories.
Which framework fits my topic?
This is a starting point. Choose the framework whose concepts you can actually measure or explore in your data.
Four widely used theories
Open each one for the key ideas, what it can guide, and an illustrative study design. The example studies are typical designs, not citations of particular papers.
Dorothea Orem: Self-Care Deficit TheoryNursing helps when people cannot meet their own self-care needs.
Core ideas
The theory has three linked parts. Self-care is what people do for themselves to maintain health and well-being. Self-care deficit arises when demand for self-care exceeds a person's ability (self-care agency). Nursing systems describe how the nurse helps: wholly compensatory, partly compensatory, or supportive-educative.
Best suited to
Chronic disease self-management, rehabilitation, patient education, and caregiving.
Example study
Question: Does a supportive-educative programme improve self-care in adults with type 2 diabetes?
Design: Quasi-experimental, intervention and control groups measured before and after. Self-care agency measured with a tool such as the Appraisal of Self-Care Agency scale, plus clinical outcomes such as HbA1c.
How the theory helps: It defines the intervention (supportive-educative system) and the outcome (self-care agency).
Callista Roy: Adaptation ModelPeople are adaptive systems responding to stimuli.
Core ideas
A person receives stimuli (focal, contextual and residual) and responds through coping processes called the regulator and cognator. Responses appear in four adaptive modes: physiological, self-concept, role function and interdependence. The nurse's role is to promote adaptation by managing stimuli.
Best suited to
Adjustment to illness, surgery, disability, or life transitions, and caregiver strain.
Example study
Question: How do family caregivers adapt in the first six months after a relative's stroke?
Design: Descriptive cross-sectional survey or mixed-methods study. Interview guides and questionnaire sections are organised by the four adaptive modes; a coping measure such as the Coping and Adaptation Processing Scale can be used.
How the theory helps: The four modes give you ready-made themes and scale subdomains.
Nola Pender: Health Promotion ModelHealth behaviour is shaped by personal factors, beliefs and feelings, and the situation.
Core ideas
Individual characteristics and prior behaviour influence behaviour-specific cognitions and affect: perceived benefits, perceived barriers, self-efficacy, activity-related feelings, interpersonal influences and situational influences. These lead to a commitment to a plan of action and, with competing demands taken into account, to the health-promoting behaviour.
Best suited to
Prevention and lifestyle research: physical activity, nutrition, screening, vaccination, and school or community programmes.
Example study
Question: Which factors predict regular physical activity in adolescents?
Design: Correlational survey with regression. Independent variables come from the model (perceived barriers, self-efficacy, peer and family support). Health-promoting behaviour can be measured with the Health-Promoting Lifestyle Profile II.
How the theory helps: It supplies the variables and the hypothesised paths.
Jean Watson: Theory of Human CaringCaring is the core of nursing and works through a transpersonal relationship.
Core ideas
Nursing is a human science of caring. Watson's original ten carative factors were later refined into clinical caritas processes, which include practising loving-kindness, being authentically present, nurturing trusting relationships, and creating a healing environment. The transpersonal caring relationship connects nurse and patient.
Best suited to
Patient experience, compassionate care, nurse well-being, palliative care and qualitative research on meaning.
Example study
Question: How do patients experience nurse caring in a surgical ward, and is it related to satisfaction?
Design: Cross-sectional survey using a caring measure such as the Caring Behaviors Inventory alongside a satisfaction scale. A phenomenological interview study is a suitable qualitative alternative.
How the theory helps: It defines caring behaviours to measure or explore.
Other frameworks you will meet
Florence Nightingale: Environmental theoryA clean, ventilated, quiet environment supports recovery.
Example study
Does reducing ward noise at night improve patient sleep quality? Nightingale's emphasis on environment frames noise, light and air as modifiable variables.
Hildegard Peplau: Interpersonal RelationsNursing is a therapeutic relationship that moves through phases.
Core ideas
Orientation, identification, exploitation (working) and resolution.
Example study
A qualitative study of how nurses and patients with depression build rapport across the phases of the relationship.
Betty Neuman: Systems ModelStressors act on a system with lines of defence and resistance.
Core ideas
Interventions are organised as primary (prevent exposure), secondary (early detection and treatment) and tertiary (rehabilitation) prevention.
Example study
A study of occupational stressors among ICU nurses with a stress-reduction programme mapped to the three prevention levels.
Imogene King: Goal Attainment TheoryNurse and patient set goals together through interaction and transaction.
Example study
Does mutual goal setting during discharge planning improve adherence and reduce readmission?
Madeleine Leininger: Culture Care TheoryCare must fit cultural values, beliefs and practices.
Example study
An ethnonursing study of postpartum care practices in a specific community, used to design culturally congruent care.
Patricia Benner: From Novice to ExpertClinical skill develops through five stages with experience.
Core ideas
Novice, advanced beginner, competent, proficient and expert.
Example study
Interviews with new graduate nurses about the transition from novice to competent practice, used to plan a preceptorship programme.
Katharine Kolcaba: Comfort TheoryComfort in physical, psychospiritual, environmental and sociocultural contexts improves outcomes.
Example study
Randomised trial of comfort-focused interventions for patients after surgery, with comfort and pain as outcomes.

Using a framework in your study
- Start from the research question, then choose the theory. Do not pick a famous theory and force the question to fit.
- Define its concepts in your own study terms and show the diagram of your conceptual framework with the variables you will measure.
- Link every objective to a concept, and every concept to an instrument or interview question.
- Use it again in the discussion. Say whether your results support the theory and where they do not.
- Read the primary source. Use the theorist's own books or recent editions, not just summaries, and cite them.
- You may combine theories, for example a nursing model to structure the intervention and a borrowed theory such as self-efficacy to explain the mechanism. Justify the combination.
