The definition of terms section of a nursing thesis lists the words a reader could misread, usually every variable plus any technical term, and defines each twice: a conceptual definition taken from a cited source, and an operational definition that says how your study measures or identifies it. It normally sits at the end of Chapter 1.

How is this different from the general definition of terms guide?
The general guide, definition of terms with conceptual and operational examples, uses twelve cross-field terms and a three-question test for deciding which terms to include. This article is for nursing students only. It covers the terms nursing theses actually define, which of them have an official definition you can quote, and how an operational definition changes when your setting is a ward, a health center or a school of nursing.
What goes in the list and what stays out?
Define a term when it is a variable in your title, when it has more than one accepted meaning, or when you are using it in a narrower sense than a reader would assume. Leave out words everyone understands, such as “hospital” or “patient.” For a nursing thesis, the safest list is every variable, every outcome, the respondent group, the setting and any clinical term. Keep the order consistent: alphabetical order or order of appearance in the study are both accepted by most schools, so use the one your research manual prefers.
Which nursing terms have an official conceptual definition you can cite?
Seven terms in this list can be tied to a document you can open and cite: the World Health Organization, the Philippine Nursing Act of 2002, the Universal Health Care Act and the Data Privacy Act. For each one below, check the original page before quoting, since your panel may check too. Operational definitions are illustrative, so adapt them to your own instrument and setting.
| No. | Term | Conceptual definition (source) | Illustrative operational definition |
|---|---|---|---|
| 1 | Health | “A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” (WHO Constitution). | Respondents’ self-rated health on a five-point item, where a higher score means better perceived health. |
| 2 | Nursing practice | A person is practicing nursing when he or she “singly or in collaboration with another, initiates and performs nursing services to individuals, families and communities in any health care setting” (Republic Act No. 9173, Section 28). | Nursing care delivered by licensed staff nurses on the [ward] during the study period, as recorded in the unit’s duty roster. |
| 3 | Patient safety | “The absence of preventable harm to a patient and reduction of risk of unnecessary harm associated with health care to an acceptable minimum” (WHO patient safety fact sheet). | The nurse’s mean score on the patient safety practices subscale of the adapted questionnaire. |
| 4 | Burnout | “A syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed,” characterised by exhaustion, mental distance or cynicism toward one’s job, and reduced professional efficacy (WHO, ICD-11). | The respondent’s total score on the burnout scale, interpreted using the scale’s own cut-offs. |
| 5 | Hypertension | High blood pressure, meaning pressure in the blood vessels of 140/90 mmHg or higher (WHO hypertension fact sheet). | Patients on the health center’s hypertension registry with a documented diagnosis. |
| 6 | Universal health care | The Universal Health Care Act (RA 11223) states, in Section 3, that it seeks to progressively realize universal health care and to ensure equitable access to quality and affordable health care goods and services, with protection against financial risk. | Awareness of the Act’s provisions, measured by the knowledge items of the questionnaire. |
| 7 | Informed consent | The Data Privacy Act (RA 10173) requires that consent be freely given, specific and informed, as defined in its Section 3(b). | The respondent’s signed agreement to participate after reading the study information sheet. |
Which other terms must a nursing thesis define?
The next thirteen terms are the ones nursing theses define most often, but their conceptual definitions depend on your theory or instrument, so the table tells you where to find it rather than inventing a quotation. Operational definitions are illustrative.
| No. | Term | Where to take the conceptual definition | Illustrative operational definition |
|---|---|---|---|
| 8 | Staff nurse | The Philippine Nursing Act of 2002 for licensure, plus your hospital’s job description. | A registered nurse employed full time on the [unit] for at least six months. |
| 9 | Knowledge | The author of your knowledge test or the guideline it is based on. | The respondent’s score out of [total] on the knowledge test, where 75 percent or higher is “adequate.” |
| 10 | Attitude | Your theoretical framework, for example the attitude component of the theory of planned behavior. | The mean of the attitude items on a five-point scale, where higher means more favorable. |
| 11 | Clinical competence | The competency framework your school uses, which should be named and cited. | Self-rated or clinical-instructor-rated score on the competency checklist. |
| 12 | Quality of nursing care | The model or instrument you adopt, such as a patient-perceived quality scale. | The mean patient rating on the care quality scale during the admission period. |
| 13 | Patient satisfaction | The original authors of the satisfaction scale you use. | The patient’s mean score on the satisfaction scale at discharge. |
| 14 | Hand hygiene compliance | The hand hygiene guideline your hospital follows, cited by name and year. | The percentage of observed opportunities in which hand hygiene was performed, over [number] observations. |
| 15 | Nurse-patient communication | The communication scale’s authors or your framework. | The mean score on the communication subscale rated by patients. |
| 16 | Medication adherence | The adherence scale’s authors. | The patient’s score on the adherence scale in the past [period]. |
| 17 | Self-efficacy | Bandura’s 1977 paper in Psychological Review, or the scale developer. | The total score on the self-efficacy scale. |
| 18 | Perceived stress | The author of the stress scale you adopt. | The total stress score, interpreted with the scale’s own categories. |
| 19 | Caring behavior | The caring theory or scale in your framework. | The mean rating on caring behavior items by patients or students. |
| 20 | Clinical exposure | Your school’s clinical education policy. | The number of hours the student has spent in clinical rotation during the semester, from the school’s records. |
For several of these, the real source is your chosen instrument. Where to find and compare instruments for nursing is covered in the nursing patient satisfaction item bank, and where to find local studies that already define these terms is in where to find previous nursing theses and studies.
How do you write a good conceptual definition?
- Find the definition at its source. A WHO document, a law, a theorist’s paper or the instrument’s manual beats a textbook summary of another thesis.
- Quote or paraphrase it, then cite it. A short quotation marks that the wording belongs to the source. If you paraphrase, still cite.
- Keep it to the sense you use. If the source gives a long definition, you may use the part relevant to your study, but do not distort it.
- Use the same term everywhere. If you call it “nurse burnout” in the title, do not call it “job stress” in Chapter 4.
How do you write a good operational definition?
An operational definition answers four questions: what is measured, in whom, with which tool, and how scores are interpreted. A formula you can reuse is: “[Term] refers to [measure] of [population] as determined by [instrument or record] during [period], where [higher or lower] means [interpretation].” Check it with two tests. First, could someone else reading it collect the same data? Second, does the measure match the instrument you describe in Chapter 3? If your Chapter 3 uses a different tool than the definition names, the panel will notice. Worked tables that connect variables, indicators and items are in operationalization of variables table examples and the nursing Chapter 3 consistency matrix.
How does the operational definition change with the setting?
The same term needs a different operational definition depending on where you collect data. Take “patient safety.” In a hospital ward study, it may be the nurse’s mean score on a patient safety practices subscale, as in the table above. In a health center study, it may be the proportion of visits in which the nurse completed a patient identification check, taken from a short observation sheet over a stated number of visits. In a school of nursing study, it may be the student’s score on a medication-safety knowledge test taken before clinical duty. The conceptual definition, the WHO wording, stays the same in all three, but a reader of your thesis can only reproduce the study if the operational version matches the real setting.
The same applies to respondents. “Staff nurse” on a surgical ward and “community health nurse” in a barangay health station do different work, so a definition borrowed from one study can mislead when you study the other. State the unit, the minimum length of service and the employment type, and keep these identical to the inclusion criteria you write in Chapter 3. If the definition says six months of service and your sampling section says one year, the panel will ask which is true.
A sample layout for the section
Here is how two entries look on the page, using the format many Philippine schools accept. The terms are illustrative:
Burnout. Conceptually, a syndrome resulting from chronic workplace stress that has not been successfully managed, characterised by exhaustion, mental distance from one’s job and reduced professional efficacy (World Health Organization, 2019). Operationally, the respondent’s total score on the burnout scale used in this study, where higher scores indicate greater burnout.
Staff nurse. Conceptually, a nurse licensed under Republic Act No. 9173 who provides direct nursing care. Operationally, a registered nurse employed full time on the medical-surgical wards of [hospital] for at least six months at the time of data collection.
Notice that the second entry avoids a conceptual definition it could not quote, and explains the operational criteria in the setting. The same pattern works for every term in your own list. For the other Chapter 1 parts that surround this section, compare your draft with the scope and delimitation and statement of the problem examples on this site, and for a full model, see a BSN nursing thesis sample.
What mistakes get the section returned?
- Defining only the conceptual meaning, so no one knows how the variable was measured.
- Copying definitions from another thesis, including its errors and its outdated sources.
- Giving an operational definition that does not match the instrument in Chapter 3.
- Defining everyday words, and skipping the technical ones.
- Changing a term’s name between chapters.
- Quoting a definition without a citation, or from a source you cannot show to the panel.
Frequently asked questions
Where does the definition of terms go in a nursing thesis?
Usually at the end of Chapter 1, after the scope and delimitation. Some schools place it in Chapter 2, so check your research manual.
How many terms should I define?
Define every variable and every term your readers could understand in more than one way. The number depends on your study, and your adviser may have a preference.
Do I need both a conceptual and an operational definition?
For variables, yes if your school’s format asks for both. Conceptual definitions come from a source, while operational definitions say how your study measures or identifies the term.
Can I use a dictionary definition?
For common words, perhaps, but nursing terms should come from authoritative sources such as WHO, the law, a nursing theorist or the author of your instrument.
Should the terms be alphabetical?
Either alphabetical order or order of appearance in the study is acceptable. Choose one, and keep it consistent.
Is an operational definition the same as the instrument?
No. The operational definition states what you measure and how you interpret it. The instrument is the tool you use to measure it.
Can I copy definitions from a previous thesis?
No. Trace each definition back to its original source, cite that source, and write the operational definition for your own study.
What if two authors define a term differently?
Choose the one that matches your study, cite it, and say in a sentence why you chose it. Do not blend two definitions without saying so.
Keep your terms consistent from Chapter 1 to Chapter 5
Tesify helps you structure Chapter 1, including your definition of terms, so each variable is defined once and used the same way throughout. Over 9,000 students have used Tesify across more than 15,000 chapters, and the thesis stays 100% written by you.
