J E Johnson, D R Lauver, L M Nail

    Journal of Consulting and Clinical Psychology
    |June 1, 1989
    PubMed
    Summary

    Providing men with prostate cancer detailed information about radiation therapy (RT) improved functional coping. This intervention reduced disruption during and after treatment, supporting self-regulation theory in managing illness stress.

    Area of Science:

    • Psychology
    • Oncology
    • Health Services Research

    Background:

    • Patients undergoing radiation therapy (RT) often experience functional disruption and negative mood.
    • Understanding the psychological mechanisms underlying coping with RT is crucial for improving patient outcomes.
    • Self-regulation and emotional-drive theories offer potential frameworks for explaining intervention effects.

    Purpose of the Study:

    • To evaluate self-regulation and emotional-drive theories in explaining the impact of a concrete informational intervention on coping with radiation therapy.
    • To assess the intervention's effect on functional disruption and negative mood in prostate cancer patients undergoing RT.
    • To identify mediators of the intervention's effect on patient outcomes.

    Main Methods:

    • A randomized controlled trial involving 84 men with prostate cancer undergoing RT.
    • An experimental group received an informational intervention describing the RT experience in concrete, objective terms.
    • A comparison group received standard care.
    • Outcomes measured included functional disruption and negative mood during and up to 3 months post-RT.

    Main Results:

    • The informational intervention significantly reduced functional disruption during and for 3 months following RT compared to the control group.
    • The intervention did not significantly affect negative mood.
    • Mediation analysis indicated that similarity between expectations and experience, and degree of understanding, explained the intervention's effect on function, supporting self-regulation theory.
    • Emotional-drive theory was not supported by the findings.

    Conclusions:

    • Concrete, objective information about radiation therapy can improve functional coping in prostate cancer patients.
    • Self-regulation theory provides a valuable framework for understanding how informational interventions enhance coping with physical illness.
    • These findings support information-processing explanations of self-regulation in managing stressful medical experiences, extending previous research with surgical patients.
