The caregivers and patients included in the research were also supposed to have sixth grade education at the minimum and be in a position to read and comprehend English. They should also attain a score of at least seven in the Short Portable Mental Status Questionnaire (SPMSQ) as well as at least 40 in the Palliative Performance Scale (PPS). Since the study concentrated on management of pain, constipation and dyspnea, the patients included in the research had to be experiencing two of them.
A sample of 329 home care patients suffering from cancer and family caregivers were selected and randomly grouped into three categories. One control group comprised of 109 people received standard care, another group with the same number received standard care and friendly visits while the third group comprised of 111 people received standard care and COPE intervention. This method of sampling is known as cluster sampling in which case naturally occurring groups would be selected and be included in a sample. In this method, the population would be divided into groups or samples. In some cases, rather than collecting data from every group, a sub-sample would be used.
Economical- expenditure is one of the major concerns in any sampling method. However, since the research will be carried out on clusters, the expenditure is tremendously reduced due to the fewer listing efforts incorporated (William, 2007).
Feasibility- cluster sampling method is also more feasible when carrying out research on large populations (William, 2007). Given that the population in the large hospice is in excess of 300, carrying out comprehensive research may not be very feasible and therefore, clustering the samples would make it more feasible.
In carrying out any form of research, the vulnerability of the variables used in the samples is taken into consideration (William, 2007). In essence, the patients and caregivers used in the research are quite vulnerable given the
