Sampling issues using the grounded theory methodology: Applicability to family caregiving research of clients with dementia and intellectual disability

Abstract

Sampling strategies and techniques should be strategically thought-through and carefully written in a research proposal in such a way that when it comes to implementing the project these strategies can be flexibly followed so as to ensure smooth data collection. Ultimately, a well-planned sampling strategy is an important step to ensuring that the project also finishes on time. In undertaking funded grounded theory (GT) qualitative research projects on family caregiving of clients with dementia and intellectual disability, pertinent sampling issues encountered with these client groups have included sampling size, recruitment difficulties, disclosure resistance, social desirability bias, and data saturation. These issues will be discussed in relation to the past decade of published literature that use the GT methodology, together with the sampling challenges we have encountered from our research on family caregivers whose relatives have used community care and residential care home services. Some suggestions to enhance recruitment efforts and sampling techniques in GT research projects will be provided so as to promote more fruitful discussions of the identified issues.
