Results from the research showed that complicated grief was predisposed by the following factors; female gender ,confidence interval, spouse relationship, parents–children relationship, lack of religious, unavailable family support, and history of mood co-morbidity.
The authors have put enough work on previous literature concerning the research. Cotrrell and McKenzie (40) says people often neglect literature review and its importance of review and most times. As a matter of fact, they blame literature review for delay in starting the research. Literature review helps justify the importance of the research while at the same time put the research in historical perspective.
This research has not indicated a clear hypothesis for the whole study. Nonetheless, the researchers have developed one null hypothesis stating that there is no significant relationship between variables. The other hypothesis states that female gender might be of increased risks for complicated grief compared with male.
The authors have clearly established a relevant theoretical framework for the study. The authors argue that the death of cancer patients leaves their caregivers with complicated grief. The authors explain that this is caused by moments and times shared by the two parties.
The authors develop a theoretical time it takes for an individual to grief the loss of a loved one. The study works with an average period of 8.9 months. This concept helps the study develop a time line for different activities.
The authors have used an experimental approach in the study. The study has set out orderly procedures trying to verify or establish the validity of the hypothesis. Experiment is a better approach when establishing insight on cause-and-effect by demonstrating the consequences of manipulation of a particular factor. Nevertheless, this journal has its uniqueness in that it is one of the few nursing journals that do not have a clear hypothesis. Thus, researchers have
