Purpose:
To construct a questionnaire for measuring knowledge of a diabetic diet and validate its contents.
Methods:
This study was carried out in three stages: (a) generation of items, (b) apparent and content validation, (c) cognitive pilot test.
Findings:
An 88-item questionnaire was obtained with a content validity index and a representativeness index of 0.87. The experts modified the items that did not reach the preset values. The cognitive test was shown to be feasible, with good exploratory values of reliability and concurrent validity.
Conclusions:
The CoNOCidiet-Diabetes questionnaire was obtained from the NOC outcome "Knowledge: Prescribed Diet" and its contents were validated.
Implications For Nursing Practice:
This research shows the usefulness of the NOC for generating tools to measure health outcomes sensitive to nursing interventions.
