The Development of the Inadvertent Perioperative Hypothermia Knowledge Test (IPH-KT).

PURPOSE: This study aimed to develop the inadvertent perioperative hypothermia knowledge test (IPH-KT) for health care professionals and examine its validity and reliability.

DESIGN

The methodological and cross-sectional study design was used.

METHODS

The research was carried out with 326 nursing students in Turkey. Data for the study were collected using a demographic information form and the IPH-KT.

FINDINGS: The item difficulty index and item distinctiveness index of the questions included in the draft form of the 25-item test ranged from 0.03 to 0.81 and from 0.25 to 0.99, respectively. After the analyses, 8 items were excluded from the draft test, and the final version of the test consisted of 17 questions. The item difficulty index of the final test ranged from 0.30 to 0.96, and the item distinctiveness index ranged from 0.33 to 0.81. The reliability of the test was determined using the Kuder-Richardson formula 20 and found to be 0.72, indicating high internal consistency. Therefore, the IPH-KT was accepted as a reliable test.

CONCLUSIONS

The study revealed that the questions in the IPH-KT had varying difficulty levels and a high ability to discriminate between individuals with knowledge of IPH and those without. The results demonstrated that the test had good content and face validity and showed high reliability for measuring the IPH knowledge of nursing students.
