Purposive sampling is particularly useful in nursing for several reasons:
1. Targeted Expertise: Researchers can select participants who have specific knowledge or experience with a health condition or treatment, providing more in-depth and relevant data. 2. Resource Efficiency: This method can be more efficient in terms of time and resources, as it focuses on a smaller, more relevant sample. 3. Rich Data: By selecting participants who are information-rich, researchers can gather detailed and comprehensive data that might not be available through random sampling.
