A longitudinal study on illness perceptions in hemodialysis patients: changes over time

Area of Science:

• Nephrology
• Psychology
• Self-Regulation Theory

Background:

• Self-regulatory theory links illness perceptions to self-management behaviors.
• Understanding changes in disease perception is crucial for patients with chronic conditions.

Purpose of the Study:

• To investigate the evolution of illness perceptions in hemodialysis patients over a six-year period.
• To assess how long-term treatment affects patients' views on their end-stage renal disease (ESRD).

Main Methods:

• Longitudinal study involving 81 hemodialysis patients initially assessed in 2005 and followed up in 2011.
• Illness perceptions were measured using the Illness Perceptions Questionnaire-Revised (IPQ-R).
• Statistical analysis examined changes in perception components and their association with mortality.

Main Results:

• Patients reported a stronger perception of a chronic disease timeline and increased belief in hemodialysis efficacy.
• Perceptions of disease consequences and emotional response intensity decreased significantly.
• Perceptions of treatment control were a significant predictor of lower mortality risk (HR = 0.13, p = 0.022).

Conclusions:

• Illness perceptions in hemodialysis patients evolve over a long-term follow-up.
• Patients tend to develop more optimistic views regarding their chronic kidney disease and its management.
• Positive illness perceptions, particularly regarding treatment control, may be linked to improved survival in ESRD patients.
