Validity and Reliability of Barakat-Johnson Incontinence-Associated Dermatitis Knowledge Tool: A Methodological Study

Area of Science:

• Nursing Research
• Dermatology
• Health Sciences

Background:

• Incontinence-associated dermatitis (IAD) is a prevalent issue in healthcare settings.
• Accurate knowledge of IAD is crucial for effective prevention and management.
• The Barakat-Johnson Incontinence-Associated Dermatitis Knowledge Tool (Know-IAD) assesses this knowledge.

Purpose of the Study:

• To evaluate the validity and reliability of the Turkish translation of the Know-IAD.
• To determine the psychometric properties of the Turkish Know-IAD for use in the Turkish healthcare context.

Main Methods:

• A methodological study involving 128 nurses was conducted.
• Linguistic validity was assessed by an expert panel.
• Data analysis utilized Multidimensional Item Response Theory (mirt) and Generalized Graded Multidimensional Item Response Theory (ggmirt) in R software.

Main Results:

• The stratified alpha coefficient was 0.62, indicating moderate reliability.
• Test-retest stability was high, ranging from 0.92 to 0.94.
• Ten items had negative difficulty coefficients, and specific items were identified as particularly challenging.

Conclusions:

• The Turkish version of the Know-IAD requires further psychometric refinement.
• Adaptation is needed for effective utilization within the Turkish nursing community.
• Future research should focus on revising and validating the tool.
