The Simplified Nutritional Appetite Questionnaire (SNAQ) is the short version of the Council of Nutrition Appetite Questionnaire (CNAQ). The validation study of the questionnaires indicated that due to its short nature and reliability, the SNAQ is more recommended for clinical use.
The SNAQ is composed of four items, grouped in a dingle domain. Each question presents five options for answer which are represented by the letters from A to E. The questions are punctuated based on the following scale: A = 1, B = 2, C = 3, D = 4 and E = 5. When summed up, they give the total score of the questionnaire, which may range from 4 to 20. The lower it is, the higher the risk for weight loss. In the original instrument, indices lower or equal to 14 indicate risk for loss of at least 5% of weight in six months.
