Identifying feeding problems in mentally retarded persons: development and reliability of the screening tool of feeding problems (STEP)

Abstract

Feeding problems are extremely common among individuals with mental retardation. Palmer, Thompson, and Linscheid (1975) estimate that 33% of persons with mental retardation have severe feeding difficulties or problems. Furthermore, the consequences of untreated feeding problems can be severe if not fatal. Despite these numbers, little has been done to systematically identify these problems. The Screening Tool of Feeding Problems (STEP) was developed as a means to identify feeding problems presented by persons with mental retardation, and thus facilitate the process of identifying who would benefit from some type of behavioral or medical intervention. Items included in the STEP target feeding problems identified in the literature, in the areas of risk of aspiration, food selectivity, feeding skills deficits, food refusal and associated behavior problems, and nutrition related behavior problems. The current study describes the construction of this scale, provides psychometric data including test-retest and cross rater reliability, and factor analysis data.
