Aim:
This study aimed to evaluate the validity and reliability of the Turkish version of the Questionnaire on Best Practices for Short Peripheral Intravenous Catheter Maintenance.
Methods:
A methodological design was employed between February and May 2025, involving a sample of 276 nurses. Participants were drawn from emergency departments, internal medicine units, surgical wards, and intensive care units across hospitals in two provinces in eastern Turkey. Data were collected using two instruments: the Nurses' Information Form and the Questionnaire on Best Practices for Short Peripheral Intravenous Catheter Maintenance. Descriptive statistics, including frequencies, percentages, means, standard deviations, medians, and minimum and maximum values, were used to describe participant characteristics. Content validity was assessed through expert review, and the Content Validity Index was calculated using the Davis technique. Item discrimination and difficulty indices were computed using Microsoft Excel. Reliability analysis involved calculation of the Kuder-Richardson Formula 20 (KR-20) coefficient, alongside item-total score correlation analysis.
Results:
The KR-20 coefficient for the Questionnaire on Best Practices for Short Peripheral Intravenous Catheter Maintenance was 0.974. Analysis of the test mean scores revealed that the items were generally easy but exhibited high discriminatory power.
Conclusion:
The Turkish version of the Questionnaire on Best Practices for Short Peripheral Intravenous Catheter Maintenance demonstrated high reliability, as evidenced by its KR-20 value. The use of this questionnaire enables the identification of knowledge gaps among nursing professionals regarding best practices in short peripheral catheter care.
