Archival Research

16.6K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

Data Reporting and Recording

5.0K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Data Collection by Observations

13.0K
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 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...

Area of Science:

  • * Digital Health
  • * Longitudinal Studies
  • * Adolescent Health

Background:

  • * Intensive longitudinal studies (mDiary) utilize mobile-optimized web apps for data collection.
  • * Youth recruitment and retention present unique challenges in digital health research.

Purpose of the Study:

  • * To analyze recruitment, access, and longitudinal response paradata from a year-long youth study.
  • * To identify factors associated with enrollment and sustained participation in mobile health studies.
  • * To compare compliance patterns between youth requiring single versus multiple invitations to enroll.

Main Methods:

  • * Latent Class Analysis (LCA) to identify distinct longitudinal compliance patterns.
  • * Analysis of recruitment and response paradata from a birth cohort study.
  • * Use of a mobile-optimized web app for bi-weekly diary administration.

Main Results:

  • * A 70% person-survey response rate was achieved with mDiary.
  • * Teens with texting capability were over six times more likely to enroll and completed more diaries.
  • * Youth requiring multiple invitations showed lower enrollment and higher early attrition.
  • * Early attrition was associated with less texting access, home internet, and lower maternal education.

Conclusions:

  • * Mobile-optimized studies can achieve high response rates in adolescents.
  • * Texting capability and streamlined enrollment are crucial for youth engagement.
  • * Socioeconomic and demographic factors influence participation and retention in digital health studies.
