Illness perceptions among cancer survivors.

Area of Science:

• Oncology
• Psychology
• Health Services Research

Background:

• Cancer survivorship presents unique challenges to psychological adaptation.
• Illness perceptions significantly influence how patients cope with and adjust to cancer.

Purpose of the Study:

• To investigate the cross-sectional associations between illness perceptions, physical symptom distress, and dispositional optimism among Hong Kong Chinese cancer survivors.
• To identify factors influencing cancer survivors' adaptation and inform potential interventions.

Main Methods:

• A cohort of 1036 cancer survivors in Hong Kong completed validated questionnaires assessing illness perceptions (Brief Illness Perception Questionnaire), symptom distress (Memorial Symptom Assessment Scale Short-Form), and optimism (Life Orientation Test).
• Stepwise multiple regression analyses were employed to examine adjusted associations between these variables.

Main Results:

• Physical symptom distress was significantly associated with most dimensions of illness perception, excluding control beliefs.
• Dispositional optimism showed positive correlations with perceived control and illness understanding, but negative correlations with other illness perception dimensions.
• Illness perception domains did not significantly differ by cancer type after adjusting for sample characteristics.

Conclusions:

• Greater physical symptom distress and lower optimism levels are linked to more negative illness perceptions in cancer survivors.
• Understanding cancer survivors' illness perceptions is crucial for developing effective interventions to support their adjustment and adaptation.
