Abstract
Background and aims: A decline in appetite is associated with poor health in older adults (≥65 years). Subjective methods of appetite assessment used in older adults living in the community have not previously been fully documented and their validity and reliability have not been evaluated and described. The aims of this scoping review were to identify methods used to assess self-reported/subjective appetite as a primary outcome in studies in older adults living in the community and community settings, and to establish which, and how methods were evaluated for validity and/or reliability. Methods: A scoping review of three online databases: CINAHL, PubMed and Embase was undertaken. Results: One-hundred and one articles were included, with 30 different types of appetite assessment methods identified and categorized into three groups: Likert-scales, visual analogue scales (VAS) and question-based methods. Likert-scales were used most frequently (61 %), followed by VAS (23 %) and question-based methods. Twenty-two studies evaluated the validity and/or reliability of 11 types of appetite assessment methods (Likert-scales, n = 10, VAS, n = 1). Thirty comparators were used to evaluate validity and reliability, with predictive validity and internal consistency reliability evaluated most frequently. Likert-scales were predominantly reported to predict health risks; however, have not been validated for appetite per se. In contrast, albeit limited, VAS have been validated against ad libitum test meal energy intake. Conclusions: Agreement on best practice when evaluating the validity and reliability of assessment methods is required. Given the current evidence, a recommended method will likely depend on the context and goals of assessment.
