ObjectiveWe aimed to investigate reliability and validity of the Turkish version of the Simplified Nutritional Appetite Questionnaire (SNAQ) in geriatric outpatients.Design/SettingA cross-sectional study was designed through 2013-2016 years. At first, translation and back translation processes of the SNAQ from English to Turkish languages were done consecutively. Then construct validity was performed.ParticipantsThey were recruited among the outpatients aged >=60 years that were consecutively admitted to the geriatric outpatient clinic of the Istanbul University hospital.MeasurementsDemographic data was recorded. SNAQ, Mini Nutritional Assessment (MNA), six-item Katz activities of daily living (ADL) and eight-item Lawton instrumental activities of daily living (IADL) scales were applied.Results442 participants consisted of 305 women and 137 men with a mean age of 77.1 ± 6.8 years. The SNAQ identified 21.5% (n=95) of the participants with poor appetite. Reliability analysis showed good inter-rater reliability (r= 0.693, p< 0.05) and test-retest stability (r= 0.654, p< 0.05). Cronbach's alpha coefficient was 0.522. In terms of construct validity of SNAQ, Cohen's kappa analysis showed fair to moderate agreement between SNAQ and MNA (κ=0,355, p<0.001). Female gender, being illiterate, functional dependency in IADL were significantly associated with poor appetite. The SNAQ score was weakly correlated with scores of MNA-SF and MNA-LF (r=0.392 and r=0.380, respectively, p<0.0001 for both). There was statistically significantbut negligible correlation between the SNAQ and Katz ADL index, Lawton IADL index, and age.ConclusionTurkish version of the SNAQ is a simple measurement with sufficient reliability and validity to screen poor appetite in community-dwelling older adults.
