Development and Inter-Rater Reliability of the Mealtime Scan for Long-Term Care

Background and Objectives: Poor food intake is common in long-term care (LTC). The mealtime experience has been identified as influential, yet, research has been limited by lack of quality, standardized measures. The purpose of this study was to develop and test for inter-rater reliability the Mealtime Scan (MTS), an observational measure. Research Design and Methods: MTS was derived from the literature on ambiance, mealtime experience, social interactions at mealtimes, and social models of care. Three scales on person-centered care and physical and social environments are used to summarize key aspects observed with MTS. Two raters assessed MTS for reliability at 30 different meals conducted in 10 dining rooms, within three LTC residences. Intraclass correlation coefficient (ICC) was used to assess reliability. Results: MTS demonstrated good to excellent reliability on the three summative scales (physical ICC = 0.73, social ICC = 0.81, person-centered care ICC = 0.83) and other scalable items had good to excellent reliability (e.g., background noise ICC = 0.65, Mealtime Relational Care checklist: negative interactions ICC = 0.85). Discussion and Implications: MTS is reliable and face valid for assessing mealtime experience. Future work will explore construct validity of this measure. MTS can be used to support improving the mealtime experience for residents living in LTC.
