5. Was the sample identified in the Monteso-Curto et al. (2014) study in Question 4 representative of the population of patients diagnosed with depression? Providea rationale for your answer. 6. Study excerpt: “The sample consisted of one physician and three nurse practitioners from one medical center who were identified by peers as experts in pain management; four community-dwelling adults with self-identified current or recent pain problems; and 23 older adults with osteoarthritis pain and their five primary care physicians whose ambulatory medical care visits at one practice site were recorded as part of previous research.” McDonald, D.D. (2014). Trialing to pain control: A grounded theory. Research in Nursing & Health, 37(2), 107–116. Excerpt from page 108. Nonprobability, purposive sampling method. The study participants were specifically selected for their experience with pain management. The healthcare providers were identified as experts in pain management, and the other participants were adults experiencing and working to manage their pain. Purposive sampling involves selecting participants
with expertise to provide rich, quality data for a specific study topic (Munhall, 2012).7. Study excerpt: “Healthcare providers in 206 Vaccine for Children (VFC) offices throughout this state [Indiana] were asked to participate in an assessment of their vaccine knowledge. A mailing list of the VFC offices was obtained from a local district health department. The estimated number of medical office personnel and providers who administer and handle immunizations in each office was determined by calling each VFC office. . . .Each office manager coordinated the completion and return of the informed consents and the Immunization Knowledge Assessment Tools.” A total of 713 surveys were randomly distributed in 206 clinics and 344 surveys were returned, for a 48% response rate.

Excerpt from page 163.Probability, cluster sampling method. Strohfus et al. (2013) did not clearly identify their type of sampling method but it is consistent with multilevel cluster sampling. Since the sampling frame for the study could not be identified, the researchers identified study participants using the Vaccine for Children (VFC) offices throughout the state. Within these offices, managers were identified to collect data fromthe healthcare providers managing immunizations.
