Abstract
AIM
The present study aimed to develop the Risk Perception Scale of Disease Aggravation for older patients with non-communicable diseases and evaluate its psychometric properties.
DESIGN
Instrument development and cross-sectional validation study were conducted.
METHODS
This study contained four phases. In phase I, a systematic literature review was conducted to identify the conception of disease aggravation and risk perception. In phase II, a draft scale was formulated from face-to-face semi-structured in-depth interviews by Colaizzi's seven-step qualitative analysis method and group discussions among the researchers. In phase III, domains and items of the scale were revised in accordance with the suggestions from Delphi consultation and patient feedback. In phase IV, psychometric properties were evaluated.
FINDINGS
Exploratory and confirmatory factor analyses determined four structural factors. Convergent and discriminant validities were acceptable because the average variance extracted coefficients ranged from .622 to .725, and the square roots of the average variance extracted coefficients for the four domains were larger than those of bivariate correlations between domains. The scale also exhibited excellent internal consistency and test-retest reliability (Cronbach's alpha coefficient = .973, intraclass correlation coefficient = .840).
CONCLUSIONS
Risk Perception Scale of Disease Aggravation is a new instrument that measures the risk perception of disease aggravation for older patients with non-communicable diseases, including possible reason, serious outcome, behaviour control and affection experience. The scale contains 40 items that are scored on a 5-point Likert scale, and it has acceptable validity and reliability.
IMPACT
The scale is applied to identify different levels of risk perception of disease aggravation for older patients with non-communicable diseases. Clinical nurses can provide targeted interventions to improve older patients' risk perception of disease aggravation based on levels of risk perception during hospitalization and the period before discharge.
PATIENT OR PUBLIC CONTRIBUTION
Experts provided suggestions for revising the scale dimensions and items. Older patients participated in the scale revision process to improve the wording of the scale.
