1Centre for Public Health Nutrition, School of Integrated Health, University of Westminster, London, UK.
Summary
Choosing qualitative data collection and sampling methods for nutrition research can be daunting. This review guides researchers in selecting appropriate techniques to ensure high-quality, relevant findings.
Area of Science:
- Nutrition and Dietetics Research
- Qualitative Research Methodologies
Background:
- Qualitative research offers diverse data collection and sampling options, often lacking a single correct approach.
- Selecting appropriate methods is vital for ensuring the quality and validity of nutrition and dietetics research.
Purpose of the Study:
- To provide an overview of principal data collection and sampling techniques for qualitative nutrition research.
- To describe a framework for selecting appropriate methods aligned with research questions and philosophical underpinnings.
- To highlight the researcher's role and impact in qualitative data collection.
Main Methods:
- Review of principal qualitative data collection techniques.
- Overview of qualitative sampling strategies.
- Discussion of a framework for method selection based on research questions and study design.
Main Results:
- Identification of key qualitative data collection and sampling methods applicable to nutrition and dietetics.
- A process for method selection considering research alignment and philosophical compatibility.
- Emphasis on the researcher's reflexive role in qualitative data gathering.
Conclusions:
- Appropriate selection of qualitative data collection and sampling methods is critical for robust nutrition and dietetics research.
- Researchers should consider research questions, philosophical assumptions, and their own influence when choosing methods.
- This review serves as a guide within a broader series on qualitative research in nutrition and dietetics.

01:30Data Collection I
Data collection gathers information needed to make accurate judgments about a patient's present condition. During a health history interview, subjective data is collected from the patient, their caregivers, or family members, and objective data is collected through observations and physical assessment. Patients are the primary source of subjective data. Thus information gathered from patients through interviews, observations, and physical examination is primary data. Secondary sources of data...
01:29Data Collection II
The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and family,...
01:05Data Collection III
The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the patient.

01:08Data Collection by Observations
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.

01:07Data Collection by Survey
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...
01:13Data Collection by Experiments
Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”
