Data Collection by Survey

9.5K
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...

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 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.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

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...

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...

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.”
An example of the experimental method is a public...

    Area of Science:

    • Public Health
    • Health Informatics
    • Human-Computer Interaction

    Background:

    • Community-based participatory research (CBPR) often requires robust data collection tools.
    • The usability of Android tablet computers for data collection in CBPR settings has not been previously assessed.
    • Low-cost digital solutions are needed to enhance data collection efficiency in community research.

    Purpose of the Study:

    • To evaluate the usability of a bilingual, touchscreen computerized survey system utilizing Android tablets.
    • To assess the feasibility of using Android tablets for needs assessment surveys in a community-based participatory research context.
    • To determine participant satisfaction and system performance with Android tablet-based data collection.

    Main Methods:

    • A needs assessment survey was developed using droidSURVEY software and administered on Android tablets.
    • The study involved 201 community residents in Tampa, Florida, between November 2013 and March 2014.
    • Participants completed usability questionnaires alongside the needs assessment survey.

    Main Results:

    • The Android tablet survey system achieved a high mean usability score of 77.57 ± 17.66.
    • The average survey completion time was 23.11 ± 9.62 minutes for 63 questions.
    • An optimal 100% survey completion rate was observed, with minimal missing data (6.34% per variable).
    • No significant sociodemographic differences were found in the usability scores.

    Conclusions:

    • Android tablets offer a viable and user-friendly platform for data collection in community-based participatory research.
    • The tested system demonstrated high usability and efficiency, supporting its adoption in similar research.
    • These findings encourage the integration of mobile technology in community health research to improve data quality and participant engagement.
