Methodologic issues in palliative care psychosocial research.

B R Cassileth, E J Lusk

    Journal of Palliative Care
    |December 1, 1989
    PubMed
    Summary

    Conducting psychosocial research in palliative care is challenging due to patient fragility. Methodologically sound studies are possible by avoiding inappropriate approaches and focusing on rigorous techniques for reliable palliative care evidence.

    Area of Science:

    • Palliative Care Research
    • Psychosocial Studies
    • Clinical Research Methodology

    Background:

    • Palliative care research faces significant challenges due to patient physical and cognitive limitations.
    • Randomization, a key experimental design element, is often not feasible or ethical in palliative care settings.
    • Existing research methods must be adapted to accommodate the unique vulnerabilities of palliative care patients and staff.

    Purpose of the Study:

    • To outline methodologically sound research approaches for palliative care.
    • To identify and advocate for appropriate research techniques in this specialized field.
    • To ensure the scientific validity of studies informing palliative care practices.

    Main Methods:

    • Focusing on well-defined research questions and hypotheses.
    • Ensuring adequate sample sizes for statistical power.
    • Developing appropriate comparison groups to strengthen study validity.
    • Carefully selecting and evaluating interview guides or questionnaires.
    • Implementing strategies to mitigate interviewing bias.

    Main Results:

    • Methodologically acceptable studies are achievable despite limitations in randomization.
    • Anecdotal case reports and single-group studies are insufficient for generalizable findings.
    • Specific techniques, such as using comparison groups and validated instruments, enhance study rigor.
    • Careful planning and execution can overcome practical barriers in palliative care research.

    Conclusions:

    • Rigorous psychosocial research in palliative care is essential for advancing the field.
    • Adopting appropriate methodologies ensures the scientific integrity of palliative care evidence.
    • Valid research findings are crucial for effective communication between palliative care professionals and other healthcare providers.
