The Simplified Nutritional Appetite Questionnaire (SNAQ) is an established screening tool. This study aimed to investigate reliability, validity, and feasibility of its telephone administration (T\u2010SNAQ) in German community\u2010dwelling older adults.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This cross\u2010sectional single\u2010centre study recruited participants from April 2021 to September 2021. First, the SNAQ was translated into German according to an established methodology. After translation, reliability, construct validity, and feasibility of the T\u2010SNAQ were analysed. A convenience sample of community\u2010dwelling older adults aged \u226570\u00a0years was recruited. The following measurements were applied to all participants: T\u2010SNAQ, Mini Nutritional Assessment \u2013 Short Form (MNA\u2010SF), six\u2010item Katz index of independence in activities of daily living (ADL), eight\u2010item Lawton instrumental activities of daily living (IADL), telephone Montreal Cognitive Assessment (T\u2010MoCA); FRAIL scale, Geriatric Depression Scale (GDS\u201015) and Charlson co\u2010morbidity index as well as daily caloric and protein intake.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred twenty participants (59.2% female) with a mean age of 78.0\u00a0\u00b1\u00a05.8\u00a0years were included in the present study. The percentage of participants identified with poor appetite based on T\u2010SNAQ was 20.8% (<jats:italic>n<\/jats:italic>\u00a0=\u00a025). T\u2010SNAQ showed a good internal reliability with a Cronbach's alpha coefficient of 0.64 and a good test\u2013retest reliability [intraclass coefficient of 0.95 (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05)]. Regarding construct validity, T\u2010SNAQ was significantly positively correlated with MNA\u2010SF (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.213), T\u2010MoCA (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.225), daily energy (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.222) and protein intake (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.252) (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05).
