Area of Science:

Nutrition science
Public health
Clinical assessment

Background:

Effective dietary screening is crucial for identifying nutritional deficiencies.
Existing methods can be time-consuming and require specialized expertise.
A need exists for a rapid, valid, and reliable dietary assessment tool for clinical settings.

Purpose of the Study:

To develop and evaluate a rapid dietary screening device, the Dietary Intake Form (DIF).
To assess the validity, reliability, and acceptability of the DIF in a clinical population.
To determine the DIF's utility for identifying individuals with inadequate nutrient intake.

Main Methods:

The DIF's validity was assessed by comparing its scores with 8-day weighed food diaries and calculating Nutrient Adequacy Ratios (NAR).
Reliability was tested by repeated administration of the DIF to undergraduate students.
Acceptability was measured by completion time and percentage of incomplete forms among 135 women.

Main Results:

The DIF demonstrated strong positive correlations with weighed food diaries (r=0.83) and high test-retest reliability for various food groups (r=0.78-0.91).
The DIF was completed by 79% of participants within 4-7 minutes, indicating good acceptability.
Dietary patterns were not predictable by demographic factors in this population.

Conclusions:

The Dietary Intake Form (DIF) is a rapid, valid, reliable, and acceptable tool for identifying individuals with poor diets.
The DIF does not require nutritionist expertise for completion or evaluation, enhancing efficiency.
This screening device allows dietitians to optimize time and resources effectively in clinical practice.
