Abstract

Background
Very little research has been conducted on the fear of injection (FOI) in patients on dialysis. However, feedback from hospital practice indicate that FOI is widespread.
Objectives
The aim of this study was to develop and validate a screening instrument to assess FOI in dialysis patients.
Method and Design
A group of patients (n = 86) completed the Dialysis Fear of Injection Questionnaire (DFIQ) and the Hospital Anxiety and Depression Scale (HADS). In semi-structured interviews, these patients were also asked about their FOI, general anxiety and depressive symptoms. Various analyses were used to examine the factor structure, sensitivity, accuracy and cut-off score.
Results
The most optimal set of items consists of 9 items. These items have the sensitivity of 0.88, a specificity of 0.72 and a cut-off value of 3.5. The Cronbach's α is 0.87.
Conclusion
The DFIQ appears to be a good predictor for the presence of FOI.
Application to Practice
Nurses can use this validated screening instrument to detect FOI. The cut-off score provides a good indication for psychological counselling.
