Design and psychometric testing of the attitude towards the prevention of incontinence-associated dermatitis instrument (APrIAD).

Abstract

Despite the availability of a range of skin care products for the prevention of incontinence-associated dermatitis (IAD), prevalence remains high. Nurses' attitude is an important determinant to take into account in quality improvement projects. This study aimed to design a psychometrically test the attitude towards the prevention of incontinence-associated dermatitis instrument (APrIAD). A prospective psychometric instrument validation study was performed in a convenience sample of 217 Belgian nurses. Construct validity and reliability (internal consistency, stability) were tested. The exploratory factor analysis demonstrated a model consisting of four factors and 14 items: (a) beliefs about the impact of IAD on patients, (b) beliefs about team responsibility to prevent IAD, (c) beliefs about personal responsibility to prevent IAD, and (d) beliefs about the effectiveness of IAD prevention products and procedures. Cronbach's α was 0.72 for factor 1, 0.65 for factor 2, 0.63 for factor 3, and 0.47 for factor 4. The intra-class correlation coefficient was 0.689 (95% confidence interval [CI] 0.477-0.825) for the total instrument, 0.591 (95% CI 0.388-0.764) for factor 1, 0.387 (95% CI 0.080-0.626) for factor 2, 0.640 (95% CI 0.406-0.795) for factor 3, and 0.768 (95% CI 0.597-0.872) for factor 4. Psychometric testing of the APrIAD demonstrated adequate validity and reliability measures.
