Purpose: An increasing number of individuals in the UK develop end-stage renal failure and receive dialysis to prolong their lives. Dialysis-users report elevated levels of psychological morbidity which are associated with poorer quality of life, adjustment to illness and increased mortality. Circumscribed evidence has also identified body-image (BI) changes occurring in dialysis-users which are already known to be associated with psychological morbidity in other chronically ill populations. This study aimed to identify the prevalence of body-image disturbance (BID) in a dialysis population, correlation with psychological distress, and to identify any variables associated with increased BID and psychological morbidity. Particular attention was given to cognitive models of emotion which postulate a key role for self-consciousness and appearance-related beliefs.
Method: Between May and August 2007, 97 adult haemodialysis and peritoneal dialysis patients from a UK regional specialist centre responded to a questionnaire survey. Outcome measures comprised the Body Image Disturbance Questionnaire, Hospital Anxiety and Depression Scale, Self-consciousness Scale and the Appearance Schemas Inventory-Revised.
Results: Prevalence of anxiety and depression was 24.7% and 18.6%, respectively, with levels of BID significantly above community norms for both male and female respondents. Significant associations were found between psychological morbidity and BID and with specific aspects of appearance-schematisation and self-focus.
Conclusions: Patients should be educated regarding the likely physical consequences of dialysis-types to aid decision-making and prepare them for impacts once dialysis is commenced. Clinicians may wish to monitor dialysis-users for distress and BI difficulties at follow-up appointments. Interventions that target appearance-related beliefs and BID may be of benefit to this population.
