Sampling rare pediatric populations
Insights
Locating rare pediatric populations for nursing research presents unique challenges. This article offers practical techniques for identifying these groups, including a specific method for surveying chronically ill children.
Area of Science:
- Pediatric Nursing
- Survey Methodology
- Health Services Research
Background:
- General population sampling methods are well-established.
- Pediatric nursing research often targets special or rare populations, requiring specialized recruitment strategies.
- Effective sampling is crucial for generalizability and validity in research.
Purpose of the Study:
- To present techniques for locating rare populations in pediatric nursing research.
- To discuss the development and analysis of a specific sampling technique for a survey of chronically ill school-age children.
- To provide methodological guidance for researchers working with hard-to-reach pediatric groups.
Main Methods:
- Review of existing literature on sampling techniques for rare populations.
- Description of various strategies applicable to pediatric populations.
- Detailed case study of developing a sample frame for a time-use survey of chronically ill children.
Main Results:
- Several techniques are identified for accessing rare pediatric populations.
- The case study demonstrates a feasible approach to sampling chronically ill school-age children.
- The developed technique provides a viable sample frame for time-use research.
Conclusions:
- Specialized sampling techniques are essential for pediatric nursing research involving rare populations.
- The presented methods can enhance the ability to recruit and study these groups.
- Further research into innovative sampling strategies is warranted for pediatric populations.
Abstract:
The sampling of general populations of individuals or households for survey research is well described. However, much of the focus of pediatric nursing research is on special or rare populations. This article presents techniques that may be used to locate rare populations for pediatric nursing research. Additionally, development and analysis of one technique used to locate a sample frame for a survey of time use of chronically ill school-age children is discussed.
